Renewable and Sustainable Energy Reviews, 2016, 55: 62-77.原文The research of intelligent lighting control systemForcada NAbstractThe growing shortage of energy and the continuous improvement of the living standards of people, people for indoor lighting system for energy saving, comfort, pursue also more and more intense, the traditional lighting system is hard to meet people's needs. People want new indoor lighting control system installation designed to be simple and beautiful, and can according to the variation of indoor scene, automatically set the corresponding lighting mode. When indoor personnel quantity increasing, for instance, or indoor light dimmed, system automatically enhance indoor illumination brightness; When the researchers focused on the interior of a certain position, the brightness of the lighting system to automatically increase the corresponding position, and at the same time reduce the away from the target location of the brightness of the light; When people are watching TV, the system automatically shut off the corresponding lighting lamps and lanterns or weaken the corresponding the brightness of the lighting, etc.People expected indoor lighting system will automatically according to the change of the indoor scene, automatically switch to get the corresponding lighting model. In this way, not only can satisfy the requirement of people for the comfort of indoor lighting, also can achieve the goal of energy saving lighting.Keywords: intelligent lighting; Control system; photoelectric detection1 IntroductionNew design of indoor lighting control system it should be possible under the condition of the minimum power consumption, meet the needs of people living and working for. And existing traditional household indoor lighting control system, weadopt manual closing or disconnect switches for simple control, the controller of the dispersed, will not be able to realize the centralized control, in addition, now the traditional household lighting control system, for using single mode is also very light, system can't according to different indoor intensity of illumination and the flexibility to make corresponding adjustment, and also can't make different according to different requirements of lighting model of flexible adjustment accordingly. Single way of lighting, already caused the waste of resources, and can not meet the changes on the intensity of illumination automatically adjust the indoor environment, so as to keep the ideal intensity of illumination demand. It is because of these reasons, traditional way of indoor lighting control, now has lagged far behind the modern intelligent household demand for lighting control. In general, the condition of the traditional indoor lighting control system is simple. For traditional lighting control system, it adopts single control on line system more or the double control circuit control mode. In a single control circuit of the system, the control switch will pick up directly in the load circuit, it also can be to implement a simple function of on or off; For the double control circuit of the control system, it can be used two single-pole double switch to implement the system of dual control, but because of the connection between the switch lighting cable, therefore, when multicast integrated control, with the increase in the number of laying cable connection between switch, line installation also become very complex, the difficulty of construction projects.

Today’s intelligent lighting control system is to use a couple more twisted pair as a communication medium, namely cable intelligent lighting control system. In cable intelligent lighting control system, control network composed of twisted-pair cable connect all system control unit, a control signal from the system control unit, via the twisted-pair network spread in the whole control system, system of each control unit from control signal from the twisted pair, according to the communication protocol of the control system, in accordance with the provisions of the command action, the network intelligent control field. This kind of cable intelligent network control system has strong anti-interference ability, good communication effect, and high system stability.2 The kinds of lighting control system2.1 Dynallte intelligent lighting control systemThe control system mainly by the switch module, dimmer module, liquid crystal display touch screen control panel, intelligent sensors, clock manager, programming day, hand-held programmer and PC monitoring machine parts.

Control system of each unit is set only unit address set its function, and software system through the output unit to control the load of each circuit. General principles of the group address and the output and input cell components set up corresponding contact. When system has input, input unit into a C a Bus signal, and then will be broadcast on the C a Bus system Bus, at this point, all the output of the unit in the control system receives the signal and make a judgment, control the corresponding output circuit’s a Bus system control mode generally includes the scene control, infrared sensor control, timing control, centralized switch control, local control and group control, centralized dimming Integrated control, wide-area control and system control, etc.2.3 The EIB intelligent control system installationThe EIB (European Installation Bus) the European electrical wiring device Bus intelligent control system.EIB it is for electrical wiring device of intelligent control system, intelligent lighting system is a part of the system.EIB standard is an open nature of the control system, it can be treated by a variety of chips in a variety of platforms, and expand the space.EIB intelligent control system by the bus, bus power supply, intelligent sensor (fuzzy switch, the light sensor, mobile sensors, time controller), intelligent switch drive and other intelligent components (logical module bus coupler).EIB is a kind of typical fieldbus control system, in the EIB control system, each component is a node, the different nodes are connected in a 2 coretwisted pair of medium on the bus, they both master-slave subordinate relations, can realize the communication between each other, thereby Implement control and be controlled.3 Intelligent lighting system control strategyIntelligent lighting system, usually is to use modern computer technology, network communication technology, automatic control technology, microelectronics technology, such as science and technology, according to environmental changes, objective request, the user condition such as reserve requirements and the various information in the automatic acquisition system, and the information collected in the corresponding logic analysis, reasoning, judgment, the results according to the specific form for storage, display, transmission and feedback control to 迖the best control effect of a kind of intelligent lighting control system. Generally, intelligent lighting control system should be based on the function of the environment in a certain area, in different period of the day, according to the indoor brightness or different USES of the region to automatic control of lighting, lighting control can transition from the traditional ordinary switch control to intelligent switch control. The application of intelligent lighting technology, the purpose is for people's work and provide new life comfortable and efficient lighting environment. Intelligent lighting it is the combination of intelligent technology and conventional lighting technology, from the basic form of its composition; it can be roughly divided into two major categories.Intelligent lighting lamps and lighting system, intelligent control to intelligent control unit and intelligent sensing unit for the system of the core of intelligent switches, intelligent lamps and lanterns, etc., can be single or several of the road lights on or off the control, the control of the bright or dark, delay or simple program control, and close the remote control and induction control, etc.This control system control and sensing unit has small volume, simple structure, small control power, etc.This type of product easy to use, low cost, and thus more be applied in such small space inside the bedroom environment intelligent lighting.

Distributed Intelligent City Street Lamp Monitoring and Control System Based onWireless Communication chip nRF401Yu CHEN, Zhaoyu LIUZhengzhou Institute of Aeronautical Industry ManagementZhengzhou, Chinae-mail: chenyu@Abstract—Traditional street lamp lighting system’s control style has disadvantage of low efficient, high cost and difficult to monitor, etc, so, it has not met modern city requirement. In order to realize distributed long distance city street lamp state automatic control in real time, we introduces a kind of wireless long distance intelligent city street lamp monitoring and control system based on SCM technology, electric power carrier communication, and wireless communication technology, etc. System is composed of upper PC, main controller, and each terminal controller. Upper PC controls main controller SCM MSP430F19, and transmits control instruction to field controller, MSP430F149 controls corresponding lighting lamp switch’s state changing by wireless transceiver nRF401. Upper PC can effectively complete wireless long distance lighting equipment control in real time. Through experiments, transmission distance can reach 1000m in maximum. In addition, we design illumination monitor equipment, which can assure lamp shut down automatically when communication network failure.Keywords-street lamp monitoring and control; MSP430F149; nRF401; wireless communication; AT89C51; electric power carrier communicationI.I NTRODUCTIONStreet lamp lighting is city part of infrastructure, which plays important position at traffic safety, society security, people living, city appearance style and feature, as well as making a city strength and mature degree. Traditional street lamp controlling adopts time-controller or transformer (distribution box) to realize decentralized control, which has disadvantages of bad centralized management, and high failure rate. Due to without long distance data collection and communication function, street lamp management in real time has not been realized, so, lamp working, operation result, etc can not be centralize monitor, record, and static, which usually can not get timely maintenance. This paper introduces a kind of street lamp long distance monitoring and control system through research work principle, realization, and character, etc based on SCM technology, wireless communication technology, etc after analyzing disadvantages of traditional monitoring and control system. This system realizes lighting according to needed, and monitor alarming, which complete long distance street lamp monitoring and control and has stronger feasibility. [1]II.S YSTEM C OMPOSITION AND P RINCIPLE System is composed of each single lamp monitoring-control terminal controller equipment, street lamp monitor central station and upper PC, etc. Each street lamp monitor central station connects with work central station by wireless transmission, and central station links with upper PC through RS232/485 or USB interface by wire style. According to different of geographical distribution situation, each work central station connects with one or multiple work slave station by wireless communication links. Upper PC obtains lighting equipment switch state by communicating with terminal equipment. And work central station can communicate with upper PC by RS232/485 or USB bus interface. Upper PC displays field lighting equipment state in real time.Each single lamp monitor-control terminal controller can realize lighting lamp start or close by upper PC, because city lamp distance is longer, we can make street lamp monitor central station as data collection equipment through electric power carrier line as communication medium. That is to say, after central station connected, then connects with upper PC through interface, which can fit to large scale field needs of city and realize longer distance data transmission. Distributed network structure principle is shown as Figure 1.Figure 1. Distributed lamp monitoring and control system structure.Each monitor terminal lower PC can itself set street lamp work information or download control schema through upper PC, such as clock calendar, open/close time, etc. Upper can each street lamp working state; monitor central station node can transmit instruction to upper PC through wireless jumping communication among each nodes; each street lamp node controls its working information, and realize failure2009 International Conference on Networks Security, Wireless Communications and Trusted Computingalarming through electric power carrier line; if some lamp node failure, beyond this node and communication, as well as feedback this information to control central and upper PC. SCM MSP430F149 acts as monitor central station controller; upper PC connects with work central station by RS232/485 or USB bus and realizes information exchange, which responds whole system monitor and management. Monitor central station controller receiver all kinds of operation control command and setting parameters of upper PC, and each field street lamp controller collects switch analogy and realize long distance lighting lamp control according to control schema. Upper PC connects work central station by RS485 or USB bus interface; gets and storages monitoring data through work slave station uploading monitoring data. As well as downloading control schema and avoid system out of control phenomenon appearance because of network failure. In addition, each single street lamp controller has ability of light-intensity detection module, which can realize automatically on-off according to night or day.III. H ARDWARE C IRCUIT D ESIGNSystem street lamp monitor central station controller adopts America TI .co SCM of MSP430F149; it is a kind of low power mix-signal controller, which has 16 bit RSIC structure, 16 bit register and constant generator of CPU. On running of CPU, if it goes wrong, DCO will automatically start, and assures system work normally. If program error, we can set watch dog to solve it. And on program fleeting, watch dog will appear overflow situation, watch dog will produce reset signal, and make system restart, which can assure system running stability.A. Single Lamp Monitoring EquipmentMain function of single lamp monitor terminal is switch on-off of controlling lamp, collecting lamp working information in real time, and communication with monitor central station controller, its hardware module frameFigure 2. Single lamp monitoring and control system structure.ISL29000 working lighting intensity range is between 1lux and 10000lux, and can transfer it into currency; outputting currency is proportional to receiving lightingintensity of photodiode. Outputting currency is converted into voltage, calculate outer circumstance lighting intensity through A/D conversion, and SCM judges if street on or off. Through lighting intensity monitor module, system can realize to automatically control street lamp on-off to avoid communication failure. Lower PC can get each street lamp terminal address through setting digital port coding, and realize relay driving on-off state, as well as using currency transformer to obtain lamp working state information.Single lamp monitor terminal adopts SCM AT89C51, and realize communication with MSP430F149 through electric power carrier communication. Electric power communication module is composed by electric power carrier communication professional chip SSC P300 and SSC P111. [2]B. Wireless Transceiver Circuit DesignSystem adopts nRF401 wireless transceiver chip of Nordic of Norway as core of wireless communication module [3]. Core architecture of Bluetooth technology, the ability of anti-jamming is very strong of type of modulation FSK. The working frequency is stable and reliable and peripheral components are few. So it is adapt to design portable hand-in products. Owing to its low transmitting frequency, high receiving sensitivity and carrier frequency which value is 433MHz of ISM frequency band. nRF401 satisfies the demands of wireless supervisor and permitting license is unnecessary. nRF401 can convert standby state to common one or transmitting state to receiving one. According to real design demands, the control port PWR_UP, CS, TXEN of nRF401 connects to SCM through pull down resistance. So, when the corresponding port of MSP430F149 is in input state, owing to pull down resistance, the current consumption is nearly zero. [4] Because SCM of MSP430F149 series automatically has serial communication ports, it can be connected to transceiver circuit of nRF401. Level transform is unnecessary. The working frequency band of Radio frequency module is set by the interface CS of serial peripheral equipments of nRF401.In addition, through adjusting bias resistance of RF_PWR port, radiated power can be adjusted. The maximum radiated power can be +10dBm. Also, the chip’s VCO circuit needs external connection of VCO inductance whose value is 22nH and the inductance is very crucial. Q>433MHz, the precision is 2%. The wireless transceiver principle is shown as Figure 3.Figure 3. Wireless communication module.The structure of inspection device is as same as each detection apparatus wireless transceiver unit. The wireless interface is designed to be coil aerial with small bulk and low costs and it can be corroded to PCB board directly. It is very suit to portable and low consumption productions.C.System Anti-jamming DesignTo prevent electromagnetic jamming, this system adopts anti-jamming measure; because electromagnetic jamming frequency segment is 0.1Hz~50MHz, so, system communication adopts frequency 433MHz, which can avoid main electromagnetic interference.Under field circumstance, antenna selection can improve system anti-jamming function, so, inspection touring station selects high-gain omni-directional antenna. To avoid much more terminal station number, antenna tuning of PCB outer, and trouble of circle antenna field tuning, etc. We select low price single whip antenna and fix it on top of suitable position, which can obtain best transceiver effect. nRF401 DC near VDD adopts high character capacity to decouple, nRF401 power has been filtered and let it isolates with digital circuit. In addition, because inspection touring equipment controller connects with central station PC by RS-485 bus, output port is double end balance driver, input port is double different amplifier. So, jamming noise can be cancelled out.Because work slave station single lamp monitoring and control equipment has delay switch action, which producing micro variable voltage du/dt, and micro currency di/dt are all jamming source. Method of reducing jamming source du/dt is parallel capacity, and reducing jamming source di/dt is series inductance or resistance to increase fly wheel diode. In this system, we increase fly wheel diode of delay coil to eliminate jamming of reverse electromotive force when disconnecting coil. But, if only add fly wheel diode will produce time delay, so, we add zener diode to realize action more times in unit time. [5]IV.S YSTEM S OFTWARE D ESIGNSoftware design is anther key to realize system function. To convenient to replant and resource sharing, software system adopts structured process design scheme, which can make system has better modularity and portability. Software design is composed of single lamp monitor-control program, street lamp monitor central station control program, upper PC display-control program, wireless communication program, etc. Key of system software design is street lamp monitor station and wireless communication module design, etc. Single lamp monitor-control slave station software is responsibility to data collection and communication, etc. Wireless communication module is made up of initial program, transmitting and receiving program, etc. Because system any one of nodes can communicate with other nodes at any time. So, each monitor-control node communication program is basic same. Main program of system includes two parts, which one is street lamp monitor central station MSP430F149 receiving upper PC correct instruction, then transmitting corresponding instruction to field lighting lamp. The other part is controlling each single lamp state according to receiving instruction.A.Upper PC CommunicationUpper PC adopts VB language to design friend man-machine interface, which can reach higher control demand, and cost is lower. As well as meet many number control system requirement. We use Microsoft Comm Control communication control file that VB provides, only need compiling little program code, and can realize data transceiver. MSP430F149 SCM adopts IARC430 language to design and complete communication with upper PC. Upper PC monitor software structure flow is shown as Figure 4.Figure 4.

led照明毕业论文中英文资料外文翻译文献Renewable and Sustainable Energy ReviewsHigh-brightness LEDs—Energy efficient lighting sources and their potential in indoor plant cultivation ABSTRACTThe rapid development of optoelectronic technology since mid-1980 has significantly enhanced the brightness and efficiency of light-emitting diodes (LEDs). LEDs have long been proposed as a primary light source for space-based plant research chamber or bioregenerative life support systems. The raising cost of energy also makes the use of LEDs in commercial crop culture imminent. With their energy efficiency, LEDs have opened new perspectives for optimizing the energy conversion and the nutrient supply both on and off Earth. The potentials of LED as an effective light source for indoor agriculturalproduction have been explored to a great extent. There are many researches that use LEDs to support plant growth in controlled environments such as plant tissue culture room and growth chamber. This paper provides a brief development history of LEDs and a broad base review on LED applications in indoor plant cultivation since 1990.Contents1. Introduction2. LED development.3.

IntroductionWith impacts of climate change, issues such as more frequent and seriousdroughts, floods, and storms as well as pest and diseases are becoming more serious threats to agriculture. These threats along with shortage of food supply make people turn to indoor and urban farming (such as vertical farming) for help. With proper lighting, indoor agriculture eliminates weather-related crop failures due to droughts and floods to provide year-round crop production, which assist in supplying food in cities with surging populations and in areas of severe environmental conditions.The use of light-emitting diodes marks great advancements over existing indoor agricultural lighting. LEDs allow the control of spectral composition and the adjustment of light intensity to simulate the changes of sunlight intensity during the day. They have the ability to produce high light levels with low radiant heat output and maintain useful light output for years. LEDs do not contain electrodes and thus do not burn out like incandescent or fluorescent bulbs that must be periodically replaced. Not to mention that incandescent and fluorescent lamps consume a lot of electrical power while generating heat, which must be dispelled from closed environments such as spaceships and space stations.2. LED developmentLED is a unique type of semiconductor diode. It consists of a chip of semiconductor material doped with impurities to create a p–n junction. Current flows easily from the p-side (anode), to the n-side (cathode), but not in the reverse direction.Electrons and holes flow into the junction from electrodes with different voltages. When an electron meets a hole, it falls into a lower energy level, and releases energy in the form of a photon. The color (wavelength) of the light emitted depends on the band gap energy of the materials forming the p–n junction. The materials used for an LED have a direct band gap with energies corresponding to near-infrared, visible or near-ultraviolet light.The key structure of an LED consists of the die (or light-emitting semiconductor material), a lead frame where the die is placed, and the encapsulation which protects the die (Fig. 1).Fig.1LED development began with infrared and red devices made with gallium arsenide. Advances in materials science have made possible the production of devices with ever-shorter wavelengths, producing light in a variety of colors. J.Margolin reported that the first known light-emitting solid state diode was made in 1907 by H. J. Round. No practical use of Round’s diode was made for several decades until the invention of the first practical LED by Nick Holonyak, Jr in 1962. His LEDs became commercially available inlate 1960s. These GaAsP LEDs combine three primary elements: gallium, arsenic and phosphorus to provide a 655nm red light with brightness levels of approximately 1–10 mcd at 20mA. As the luminous intensity was low, these LEDs were only used in a few applications, primarily as indicators. Following GaAsP, GaP (gallium phosphide) red LEDs were developed. These device sex hibit very high quantum efficiencies at low currents. As LED technology progressed through the 1970s, additional colors and wavelengths became available. The most common materials were GaP green and red, GaAsP orange, and high efficiency red and GaAsP yellow. The trend towards more practical applications (such as in calculators, digital watches, and test equipment) also began to develop. As the LED materials technology became more advanced, the light output was increased, and LEDs became bright enough to be used for illumination.In 1980s a new material, GaAlAs (gallium aluminum arsenide) was developed followed by a rapid growth in the use of LEDs. GaAlAs technology provides superiorperformance over previously available LEDs. The voltage requirement is lower, which results in a total power savings. LEDs could be easily pulsed or multiplexed and thus are suitable for variable message and outdoor signs. Along this development period, LEDs were also designed into bar code scanners, fiber optic data transmission systems, and medicalequipment. During this time, the improvements in crystal growth and optics design allow yellow, green and orange LEDs only a minor improvement in brightness and efficiency. The basic structure of the material remained relatively unchanged.As laser diodes with output in the visible spectrum started to commercialize in late 1980s, LED designers used similar techniques to produce high-brightness and high reliability LEDs. This led to the development of InGaAlP (indium gallium aluminum phosphide) visible light LEDs. Via adjusting the energy band gap InGaAlP material can have different color output. Thus, green, yellow, orange and red LEDs could all be produced using the same basic technology. Also, light output degradation of InGaAlP material is significantly improved.Shuji Nakamura at Nichia Chemical Industries of Japan introduced blue LEDs in 1993. Blue LEDs have always been difficult to manufacture because of their high photon energies (>2.5 eV) and relatively low eye sensitivity. Also, the technology to fabricate these LEDs is very different and less advanced than standard LED materials. But blue is one of the primary colors (the other two being red and green). Properly combining the red, green, and blue light is essential to produce white and full-color. This process requires sophisticated software and hardware design to implement. In addition, the brightness level is low and the overall light output of each RGB die being used degrades at a different rate resulting in an eventual color unbalance. The blue LEDs available today consist of GaN (gallium nitride) and SiC (silicon carbide) construction. The blue LED that becomes available in production quantities has result in an entire generation of new applications that include telecommunications products, automotive applications, traffic control devices, and full-color message boards. Even LED TVs can soon become commercially available.Compare to incandescent light’s 1000-h and fluorescent light’s 8000-h life span, LEDs have a very significantly longer life of 100,000 h. In addition to their long life, LEDs have many advantages over conventional light source. These advantages include small size, specific wavelength, low thermal output, adjustable light intensity and quality, as well as high photoelectric conversion efficiency. Such advantages make LEDs perfect for supporting plant growth in controlled environment such as plant tissue culture room and growth chamber. Table 1 is a list of some common types of LEDs as compiled from .The chlorophyll molecules in plants initiate photosynthesis bycapturing light energy and converting it into chemical energy to help transforming water and carbon dioxide into the primary nutrient for living beings. The generalized equation for the photosynthetic process is given as:CO2 + H2O—light—>（CH2O）+ O2where (CH2O) is the chemical energy building block for thesynthesis of plant components.Chlorophyll molecules absorb blue and red wavelengths most efficiently. The green and yellow wavelengths are reflected or transmitted and thus are not as important in the photosyntheticprocess. That means limit the amount of color given to the plants and still have them grow as well as with white light. So, there is no need to devote energy to green light when energy costs are aconcern, which is usually the case in space travel.The LEDs enable researchers to eliminate other wavelengths found within normal white light, thus reducing the amount of energy required to power the plant growth lamps. The plants grow normally and taste the same as those raised in white light.Red and blue light best drive photosynthetic metabolism. These light qualities are particularly efficient in improving the developmental characteristics associated with autotrophic growth habits. Nevertheless, photosynthetically inefficient light qualities also convey important environmental information to a developing plant. For example, far-red light reverses the effect of phytochromes, leading to changes in gene expression, plant architecture, and reproductive responses. In addition, photoperiod (the adjustment of light and dark periods) and light quality (the adjustment of red, blue and far-red light ratio) also have decisive impacts on photomorphogenesis.The superimposed pattern of luminescence spectrum of blue LED (450–470 nm) and that of red LED (650–665 nm) corresponds well to light absorption spectrum of carotenoids and chlorophyll. Various plant cultivation experiments are possible when these twokinds of LED are used with the addition of far-red radiation (730–735 nm) as the light source. Along the line of the LED technology advancement, LEDs become a prominent light source for intensive plant culture systems and photobiological researches. The cultivation experiments which use such light sources are becoming increasingly active. Plant physiology and plant cultivation researches using LEDs started to peak in 1990s and become inevitable in the new millennium. Those researches have confirmed that LEDs are suitable for cultivation of a variety of algae,crop, flower, fruit, and vegetable.Some of the pioneering researches are reviewed in the followings.Bula et al. have shown that growing lettuce with red LEDs in combination with blue tubular fluorescent lamp (TFL) is possible. Hoenecke et al. have verified the necessity of blue photons for lettuce seedlings production by using red LEDs with blue TFL. As the price of both blue and red LEDs have dropped and the brightness increased significantly, the research findings have been able to be applied in commercial production. As reported by Agence France Press, Cosmo Plant Co., in Fukuroi, Japan has developed a red LED-based growth process that uses only 60% of electricity than a fluorescent lighting based one.Tennessen et al. have compared photosynthesis from leaves of kudzu (Pueraria lobata) enclosed in a leaf chamber illuminated by LEDs versus by a xenon arc lamp. The responses of photosynthesis to CO2 are similar under the LED and xenon arc lamps at equal photosynthetic irradiance. There is no statistical significant difference between the white light and red light measurements in high CO2. Some leaves exhibited feedback inhibition of photosynthesis which is equally evident under irradiation of either lamp type. The results suggest that photosynthesis research including electron transport, carbon metabolismand trace gas emission studies should benefit greatly from the increased reliability, repeatability and portability of a photosynthesis lamp based on LEDs.Okamoto et al. have investigated the effects of different ratios of red and blue (red/blue) photosynthetic photon flux density (PPFD) levels on the growth and morphogenesis of lettuce seedlings. They have found that the lettuce stem length decreases significantly with an increase in the blue PPFD. The research has also identified the respective PPFD ratio that (1) accelerates lettuce seedlings’stem elongation, (2) maximizes the whole plant dry weight, (3) accelerates the growth of whole plants, and (4) maximizes the dry weights of roots and stems. Photosynthesis does not need to take place in continuous light. The solid state nature allows LEDs to produce sufficient photon fluxes and can be turned fully on and off rapidly (200 ns), which is not easily achievable with other light sources. This rapid on–off feature has made LEDs an excellent light source for photosynthesis research such as pulsed lighting for the study of photosynthetic electron transport details. The off/dark period means additional energy saving on top of the LEDs’low power consumption.4. LEDs and indoor plant cultivation4.1. Plant tissue culture and growthTissue culture (TC), used widely in plant science and a number of commercial applications, is the growth of plant tissues or cells within a controlled environment, an ideal growth environment that is free from the contamination of microorganisms and other contaminants. A controlled environment for PTC usually means filtered air, steady temperature, stable light sources, and specially formulated growth media (such as broth or agar). Micropropagation, a form of plant tissue culture (PTC), is used widely in forestry and floriculture. It is also used for conserving rare or endangered plant species. Other uses of PTC include:1short-term testing of genetic constructions or regeneration oftrans genic plants,2 cross breeding distantly related species and regeneration of the novel hybrid,3 screening cells for advantageous characters (e.g. herbicidere sistance/tolerance),4embryo rescue (i.e. to cross-pollinate distantly related specie sand then tissue culture there sulting embryo which would normally die),5 large-scale growth of plant cells in liquid culture inside bioreactors as a source of secondary products (like recombinant proteins used as biopharmaceuticals).6production of doubled monoploid plants from haploid cultures to achieve homozygous lines more rapidly in breeding programs (usually by treatment with colchicine which causes doubling of the chromosome number).Tissue culture and growth room industries have long been using artificial light sources for production. These light sources include TFL, high pressure sodium lamp (HPS), metal halide lamp (MHL) and incandescent lamp, etc. Among them, TFL has been the most popular in tissue culture and growth room industries. However, the use of TFL consumes 65% of the total electricity in a tissue culture lab. That is the highest non-labor costs. As a result, these industries continuously seek for more efficient light sources. The development of high-brightness LED has made LED a promising light source for plant growth in controlled environments.Nhut et al. have cultured strawberry plantlets under different blue to red LED ratios as well as irradiation levels and compared its growth to that under plant growth fluorescent. The results suggest that a culture system using LED is advantageous for the micropropagation of strawberry plantlets. The study also demonstrates that the LED light source for in vitro culture of plantlets contributes to an improved growth of the plants in acclimatization.Brown et al. have measured the growth and dry matter partitioning of ‘Hungarian Wax’pepper (Capsicum annuum L.) plants grown under red LEDs compared with similar plants grown under red LEDs with supplemental blue or far-red radiation. Pepper biomass reduces when grown under red LEDs without blue wavelengths compared to plants grown under supplemental blue fluorescent lamps. The addition of far-red radiation results in taller plants with greater stem mass than red LEDs alone. Fewer leaves developed under red or red plus far-red radiation than with lamps producing blue wavelengths. The results of their research indicate that with proper combination of other wavelengths, red LEDs may be suitable for the culture of plants in tightly controlled environments.4.2. Space agricultureBecause re-supply is not an option, plants are the only options to generate enough food, water and oxygen to help make future explorers self-sufficient at space colonies on the moon, Mars or beyond. In order to use plants, there must be a light source. Standard light sources that used in homes and in greenhouses and in growth chambers for controlled agriculture here on Earth are not efficient enough for space travel. While a human expedition outside Earth orbit still might be years away, the space farming efforts are aimed at developing promising artificial light sources. LEDs, because of their safety, small mass and volume, wavelength specificity, and longevity, have long been proposed as a primary light source for space-base plant research chamber or bioregenerative life support systems .Infrared LEDs that are used in remote controls devices have other uses. Johnson et al. have irradiated oat (Avena sativa cv Seger) seedlings with infrared (IR) LED radiation passed through a visible-light-blocking filter. The irradiated seedlings exhibited differences in growth and gravitropic response when compared to seedlings grown in darkness at the same temperature. This suggests that the oat seedlings are able to detect IR LED radiation. These findings also expand the defined range of wavelengths involved in radiation–gravity (light–gravity) interactions to include wavelengths in the IR region of the spectrum.Goins et al. grow wheat under red LEDs and compare them to the wheat grown under (1) white fluorescent lamps and (2) red LEDs supplemented with blue light from blue fluorescent lamps. The results show that wheat grown under red LEDs alone displayed fewer subtillers and a lower seed yield compared to those grown under white light. Wheat grown under red LEDs + 10% BF light had comparable shoot dry matter accumulation and seed yield relative to those grown under white light. These results indicate that wheat can complete its life cycle under red LEDs alone, but larger plants and greater amounts of seed are produced in the presence of red LEDs supplemented with a quantity of blue light.The research of Goins and his team continues in plant growth chambers the size of walk-in refrigerators with blue and red LEDs to grow salad plants such as lettuce and radishes. They hope the plant growth chamber would enable space station staff to grow and harvest salad greens, herbs and vegetables during typical fourmonth tours on the outpost .4.3. AlgacultureAlgaculture, refers to the farming of species of algae, has been a great source for feedstock, bioplastics, pharmaceuticals, algae fuel, pollution control, as well as dyes and colorants. Algaculture also provides hopeful future food sources.Algae can be grown in a photobioreactor (PBR), a bioreactor which incorporates some type of light source. A PBR is a closed system, as opposed to an open tank or pond. All essential nutrients must be introduced into the system to allow algae to grow and be cultivated. A PBR extends the growing season and allows growing more species. The device also allows the chosen species to stay dominant. A PBR can either be operated in ‘‘batch mode’’or ‘‘continuous mode’’in which a continuous stream of sterilized water that contains air, nutrients, and carbon dioxide is introduced. As the algae grows, excess culture overflows and is harvested.When the algae grow and multiply, they become so dense that they block light from reaching deeper into the water. As a result, light only penetrates the top 7–10 cm of the water in most algalcultivation systems. Algae only need about 1/10 the amount of direct sunlight. So, direct sunlight is often too strong for algae. A means of supplying light to algae at the right concentration is to place the light source in the system directly.Matthijs et al. have used LEDs as the sole light source in continuous culture of the green alga (Chlorella pyrenoidosa). The research found the light output of the LED panel in continuous operation sufficient to support maximal growth. Flash operation at 5-ps pulse ‘‘on’’ duration between dark periods of up to 45 ps would stillsustain near maximum growth. While longer dark periods tend to cut the growth rate, the light flux decrease resulting from such operation does not reduce the growth as much as that of the similar flux decrease in continuous operation. Their research concludes that the use of flashing LEDs (which means intermittent light) in indoor algal culture yielded a major gain in energy economy comparing to fluorescent light sources. An additional advantage is that heat waste losses are much smaller. The most interesting discovery of this study may be that adding blue light to the red LED light did not change the growth properties.In order to take advantage of the biotechnological potential of algae, Lee and Palsson have calculated theoretical values of gas mass transfer requirements and light intensity requirements to support high-density algal cultures for the 680 nm monochromatic red light from LED as a light source. They have also designed a prototype PBR based on these calculations. Using on-line ultra filtration to periodically provide fresh medium, these researchers have achieved a cell concentration of more than 2×109cells/ml (more than 6.6%, vol/vol), cell doubling times as low as 12 h, and an oxygen production rate as high as 10 mmol oxygen/l culture/h. This research indicates that the development of a small LED-based algal photobioreactors is economically achievable.Another research of algae via LEDs is conducted by Nedbal et al. Their research is a study of light fluctuation effects on a variety of algae in dilute cultures using arrays of red LEDs to provide intermittent and equivalent continuous light in small-size (30 ml) bioreactors. The results endorse that the algae growth rates in certain calculated intermittent light can be higher than the growth rate in the equivalent continuous light. Yanagi and Okamoto has grown five spinach plants under the red LEDs and another five under 40W plant growth fluorescent lamps at the same light intensity of 125 mmol/m2/s. The dry matter production under the LEDs is slightly less than that under the fluorescent lamps. The plant leaf area under the red LEDs is also smaller than that under the fluorescent lamps. Nevertheless, they reach a conclusion that LEDs can qualify as an artificial light source for plant growth.4.4.Plant disease reductionSchuerger and Brown have used LED arrays with different spectral qualities to determine the effects of light on the development of tomato mosaic virus (ToMV) in peppers and powdery mildew on cucumbers. Their research concludes that spectral quality may alter plant disease development. Latter research regarding bacterial wilt on tomato has confirmed this conclusion and demonstrates that spectral quality may be useful as a component of an integrated pest management program for space-based ecological life support systems. Schuerger et al. have shown that the spectral quality effects on peppers’ anatomical changes in stem and leaf tissues are corr elated to the amount of blue light in primary light source.Miyashita et al. use red LEDs (peak wavelength: 660 nm) and white fluorescent lamps as light sources for potato plantlets growth in vitro. They found that shoot length and chlorophyll concentration of the plantlets increases with increasing 630–690 nm red photon flux (R-PF) while there are no significant differences in dry weight and leaf area of the plantlets with different R-PF levels. This means red lightaffects the morphology rather than the growth rate of potato plantlets in vitro. As a result, they suggest that red LEDs can be used for controlling plantlet morphology in micropropagation.5. Intermittent and photoperiod lighting and energy savingTime constants for photosynthetic processes can be divided into three ranges: primary photochemistry, electron shuttling, and carbon metabolism. These three photosynthetic processes can be uncoupled by providing pulses of light within the appropriate range for each process. At high frequencies, pulsing light treatments can be used to separate the light reactions (light harvesting and charge separation) from the dark reactions (electron shuttling) of photosynthetic electron transport. LEDs’ flexible pulsating ability can be coupled with such characteristics of photosynthesis and lead to additional energy saving.Tennessen et al. use LEDs to study the effects of light pulses (micro- to milli-second) of intact tomato leaves. They found that when the equivalent of 50 mmol photons mp -2s-1 is provided during 1.5 ms pulses of 5000 mmol photons mp -2s-1 followed by 148.5 ms dark periods, photosynthesis is the same as in continuous 50 mmol photons mp -2s-1 . Data support the theory that photons in pulses of 100 ps or shorter are absorbed and stored in the reaction centers to be used in electron transport during the dark period. Pigments of the xanthophyll cycle were not affected by pulsed light treatments. This research suggests that, instead of continuous light, using effectively calculated intermittent light (which means less energy consumption) might not affect the plant production.Jao and Fang have investigated the effects of intermittent light on growth of potato plantlets in vitro. They also use conventional TFLs for the experiment to explore the electrical savings realized by adjusting the frequency and duty ratio of LEDs. TFLs provide continuous fluctuating light at 60 Hz while LEDs provide nonfluctuating light and pulse light of the preset frequency and duty ratio. When the growth rate is the only concern, LEDs at 720 Hz (1.4 ms) and 50% duty ratio with 16-h light/8-h dark photoperiod stimulated plant growth the most. When energy consumption is the major concern, using LEDs at 180 Hz (5.5 ms) and 50% duty ratio with 16-h light/8-h dark photoperiod would not significantly sacrifice plant growth, especially when energy for heat removal is also taken into account.6. ConclusionsThe first sustained work with LEDs as a source of plant lighting occurred in the mid-1980s when a lighting system for plant growth was designed for space shuttles and space stations for it is realized that people cannot go to the Moon, Mars, or beyond without first mastering the art of indoor farming on Earth. As the performance of LED continues to improve, these lighting systems progress from red only LED arrays using the limited components available to high-density, multi-color LED chip-on-board technologies. Today, space age gardeners who have been testing high-efficiency light sources for future space colonists have identified energy efficient LEDs as the major light source not only to grow food but also to generate and purify oxygen and water—key sustainers of human life. The removal of carbon dioxide from a closed environment is another added benefit.LEDs are the first light source to provide the capability of true spectral composition control, allowing wavelengths to match to plant photoreceptors to optimize production as well as to influence plant morphology and composition. They are easily integrated into digital control systems, facilitating complex lighting programs like varying spectral composition over the course of a photoperiod or with plant development stage. LEDs do not contain mercury. They are safer to operate than current lamps since they do not have glass envelopes or high touch temperatures.While the process of photosynthesis does not require continuous light of full spectrum, LEDs can produce sufficient photon fluxes of specific wavelength on and off rapidly. Such mechanism of photosynthesis coupled with the solid state characteristics of LEDs constitute two ways of energy saving (cutting out unnecessary spectrum segment and turning off the light periodically) on top of the LEDs’ low power consumption. These are not easily achievable with other light sources.This paper provides a broad base review on LED applications in horticulture industry since 1990. These researches pave the way for the researches of similar types using different species and lead to comparable conclusion that LEDs are well qualified to replace its more energy demanding counterparts as controlled environment light source for agricultural research such as providing tissue culture lighting as well as supplemental and photoperiod lighting for greenhouses.With the energy it can save, LED’s becoming ec onomically feasible in large-scale indoor farming lighting applications is just around the corner.再生可持续能源评论高亮高效节能LED灯的来源及其在室内植物栽培中的潜力摘要自1980年中期以来，光电子技术的迅猛发展，显著调高了发光二极管（LED）的亮度和效率。

In addition, the intelligent lighting control system for fluorescent lamp dimming control, etc., due to the use of a fluorescent active tunable filter electronic ballast technology and reduce the harmonic content, to improve the power factor and reduce the low-voltage reactive power loss.1.2 to extend the life span of light sourceLight source can not only extend the life savings, but also significantly reduce the workload of lamp replacement, reducing the operating costs of lighting systems, management and maintenance becomes simple.Both the thermal radiation source, or gas discharge light source, voltage fluctuations are a major cause of light damage. Therefore, the effective suppression of the fluctuations in voltage can extend the life of light sources.Intelligent lighting control system can successfully suppress the surge voltage power grid, but also have a voltage limit and the conjugate stream functions of filtering, to avoid over-voltage and under-voltage damage to the light.

智能调光英文文献As lighting accounts for a substantial proportion of energy consumption in buildings, intelligent lighting control systems have been widely used to improve energy efficiency and create a comfortable lighting environment. Among various intelligent lighting control technologies, intelligent dimming control is one of the key components for achieving energy-efficient lighting systems. This article discusses the concept, working principle, and benefits of intelligent dimming control.1. Concept of Intelligent Dimming ControlIntelligent dimming control is a technology that adjusts the brightness levels of lighting fixtures according to the needs of users or the environment. The traditional dimming control methods, such as the triac dimmer, only dim the lighting fixtures to a certain brightness level, regardlessof the actual needs of users or the environment. In contrast, intelligent dimming control technologies, such as PWM (pulse width modulation), DALI (digital addressable lighting interface), and Zigbee, can achieve smooth and accurate dimming control, as well as provide feedback and monitoring functions.2. Working Principle of Intelligent Dimming ControlIntelligent dimming control systems work by sending commands to the lighting fixtures or the dimming devices. The commands can be transmitted wirelessly or through wired connections, such as Ethernet cables, power lines, ortwisted-pair cables. The lighting fixtures or the dimmingdevices receive the commands and adjust the brightness levels accordingly. The feedback and monitoring functions ofintelligent dimming control systems can provide real-timedata on energy consumption, failure status, and occupancy detection, which can help users or managers optimize the lighting environment and reduce energy waste.3. Benefits of Intelligent Dimming ControlIntelligent dimming control can bring many benefits to building owners, users, and the environment:- Energy saving: By adjusting the brightness levels of lighting fixtures according to the actual needs, intelligent dimming control can save up to 60% of lighting energy consumption compared with traditional dimming control methods. - Comfortable lighting environment: Intelligent dimmingcontrol can provide adjustable brightness levels, color temperatures, and color rendering indices, which can create a comfortable and adaptive lighting environment that meets the needs of different users and activities.- Healthy lighting environment: Intelligent dimming control can simulate natural daylight changes, prevent flicker, and reduce glare, which can improve visual comfort, reduce eyestrain, and enhance the circadian rhythm of human beings.- Flexible and customizable lighting scenarios: Intelligent dimming control can create different lighting scenes and modes, such as task lighting, accent lighting, mood lighting, and emergency lighting, which can meet different functional, aesthetic, and safety requirements.- Intelligent management and maintenance: Intelligent dimming control systems can provide real-time data on energy consumption, failure status, and occupancy detection, which can help users or managers optimize the lighting environment,schedule maintenance, and reduce operating costs.In conclusion, intelligent dimming control is a promising technology for achieving energy-efficient, comfortable, and healthy lighting systems. With the development of IoT (Internet of Things) and AI (Artificial Intelligence), intelligent dimming control systems can be further integrated with other building systems, such as HVAC (heating, ventilation, and air conditioning), security, and occupancy, to create smarter and more sustainable buildings.。

Both the thermal radiation source, or gas discharge light source, voltage fluctuations are a major cause of light damage. Therefore, the effective suppression of the fluctuations in voltage can extend the life of light sources. Intelligent lighting control system can successfully suppress the surge voltage power grid, but also have a voltage limit and the conjugate stream functions of filtering, to avoid over-voltage and under-voltage damage to the light. The use of soft-start and soft turn-off technology, to avoid the impact of currentdamage to the light. Through this method, the light source to extend the life span of usually 2 to 4 times.1.3 To improve the working environment improve efficiencyGood working environment is to improve the efficiency of a necessary condition. Good design and reasonable choice of light source, lamps and lighting quality control systems, can improve the quality of lighting. Intelligent lighting control system dimming control panel module to replace the traditional lighting of the level switch control is an effective way to control the overall room illumination value, thereby enhancing the uniformity of illumination. At the same time, this control method used in electrical components have also solved the stroboscopic effect, will not create uncomfortable, confused, feeling eyestrain.1.4 To achieve a variety of lighting effectsA wide range of lighting control, the same building can have a variety of artistic effect, for a lot of construction hyperchromic.

英语原文Intelligent Traffic Light Controlby Marco Wiering The topic I picked for our community project was traffic lights. In a community, people need stop signs and traffic lights to slow down drivers from going too fast. If there were no traffic lights or stop signs, people’s lives would be in danger from drivers going too fast.The urban traffic trends towards the saturation, the rate of increase of the road of big city far lags behind rate of increase of the car.The urban passenger traffic has already become the main part of city traffic day by day and it has used about 80% of the area of road of center district. With the increase of population and industry activity, people's traffic is more and more frequent, which is unavoidable. What means of transportation people adopt produces pressure completely different to city traffic. According to calculating, if it is 1 to adopt the area of road that the public transport needs, bike needs 5-7, car needs 15-25, even to walk is 3 times more than to take public transits. So only by building road can't solve the city traffic problem finally yet. Every large city of the world increases the traffic policy to the first place of the question.For example，according to calculating, when the automobile owning amount of Shanghai reaches 800,000 (outside cars count separately ), if it distributes still as now for example: center district accounts for great proportion, even when several loop-lines and arterial highways have been built up , the traffic cannot be improved more than before and the situation might be even worse. So the traffic policy Shanghai must adopt , or called traffic strategy is that have priority to develop public passenger traffic of city, narrow the scope of using of the bicycle progressively , control the scale of growth of the car traffic in the center district, limit the development of the motorcycle strictly.There are more municipals project under construction in big city. the influence on the traffic is greater.Municipal infrastructure construction is originally a good thing of alleviating the traffic, but in the course of constructing, it unavoidably influence the local traffic. Some road sections are blocked, some change into an one-way lane, thus the vehicle can only take a devious route . The construction makes the road very narrow, forming the bottleneck, which seriously influence the car flow.When having stop signs and traffic lights, people have a tendency to drive slower andlook out for people walking in the middle of streets. To put a traffic light or a stop sign in a community, it takes a lot of work and planning from the community and the city to put one in. It is not cheap to do it either. The community first needs to take a petition around to everyone in the community and have them sign so they can take it to the board when the next city council meeting is. A couple residents will present it to the board, and they will decide weather or not to put it in or not. If not put in a lot of residents might be mad and bad things could happened to that part of the city.When the planning of putting traffic lights and stop signs, you should look at the subdivision plan and figure out where all the buildings and schools are for the protection of students walking and riding home from school. In our plan that we have made, we will need traffic lights next to the school, so people will look out for the students going home. We will need a stop sign next to the park incase kids run out in the street. This will help the protection of the kids having fun. Will need a traffic light separating the mall and the store. This will be the busiest part of the town with people going to the mall and the store. And finally there will need to be a stop sign at the end of the streets so people don’t drive too fast and get in a big accident. If this is down everyone will be safe driving, walking, or riding their bikes.In putting in a traffic light, it takes a lot of planning and money to complete it. A traffic light cost around $40,000 to $125,000 and sometimes more depending on the location. If a business goes in and a traffic light needs to go in, the business or businesses will have to pay some money to pay for it to make sure everyone is safe going from and to that business. Also if there is too many accidents in one particular place in a city, a traffic light will go in to safe people from getting a severe accident and ending their life and maybe someone else’s.The reason I picked this part of our community development report was that traffic is a very important part of a city. If not for traffic lights and stop signs, people’s lives would be in danger every time they walked out their doors. People will be driving extremely fast and people will be hit just trying to have fun with their friends. So having traffic lights and stop signs this will prevent all this from happening.Traffic in a city is very much affected by traffic light controllers. When waiting for a traffic light, the driver looses time and the car uses fuel. Hence, reducing waiting times before traffic lights can save our European society billions of Euros annually. To make traffic light controllers more intelligent, we exploit the emergence of novel technologies such as communication networks and sensor networks, as well as the use of more sophisticated algorithms for setting traffic lights. Intelligent traffic light control does not only mean thattraffic lights are set in order to minimize waiting times of road users, but also that road users receive information about how to drive through a city in order to minimize their waiting times. This means that we are coping with a complex multi-agent system, where communication and coordination play essential roles. Our research has led to a novel system in which traffic light controllers and the behaviour of car drivers are optimized using machine-learning methods.Our idea of setting a traffic light is as follows. Suppose there are a number of cars with their destination address standing before a crossing. All cars communicate to the traffic light their specific place in the queue and their destination address. Now the traffic light has to decide which option (ie, which lanes are to be put on green) is optimal to minimize the long-term average waiting time until all cars have arrived at their destination address. The learning traffic light controllers solve this problem by estimating how long it would take for a car to arrive at its destination address (for which the car may need to pass many different traffic lights) when currently the light would be put on green, and how long it would take if the light would be put on red. The difference between the waiting time for red and the waiting time for green is the gain for the car. Now the traffic light controllers set the lights in such a way to maximize the average gain of all cars standing before the crossing. To estimate the waiting times, we use 'reinforcement learning' which keeps track of the waiting times of individual cars and uses a smart way to compute the long term average waiting times using dynamic programming algorithms. One nice feature is that the system is very fair; it never lets one car wait for a very long time, since then its gain of setting its own light to green becomes very large, and the optimal decision of the traffic light will set his light to green. Furthermore, since we estimate waiting times before traffic lights until the destination of the road user has been reached, the road user can use this information to choose to which next traffic light to go, thereby improving its driving behaviour through a city. Note that we solve the traffic light control problem by using a distributed multi-agent system, where cooperation and coordination are done by communication, learning, and voting mechanisms. To allow for green waves during extremely busy situations, we combine our algorithm with a special bucket algorithm which propagates gains from one traffic light to the next one, inducing stronger voting on the next traffic controller option.We have implemented the 'Green Light District', a traffic simulator in Java in which infrastructures can be edited easily by using the mouse, and different levels of road usage can be simulated. A large number of fixed and learning traffic light controllers have already been tested in the simulator and the resulting average waiting times of cars have been plotted and compared. The results indicate that the learning controllers can reduce average waiting timeswith at least 10% in semi-busy traffic situations, and even much more when high congestion of the traffic occurs.We are currently studying the behaviour of the learning traffic light controllers on many different infrastructures in our simulator. We are also planning to cooperate with other institutes and companies in the Netherlands to apply our system to real world traffic situations. For this, modern technologies such as communicating networks can be brought to use on a very large scale, making the necessary communication between road users and traffic lights possible.中文翻译：智能交通信号灯控制马克·威宁我所选择的社区项目主题是交通灯。

Abstract: In this paper, a brief description of evanescent wave fiber optic methane sensor for the detection of methane gas in the range of 0-10% has been given. The Fiber Bragg grating (FBG) based strain sensor for condition monitoring of steel rope has been described. Laboratory model of both the sensors and their results have been enunciated. Fiber optic, being a dielectric, non-metallic, non-sparking, free from electromagnetic interferences is an intrinsically safe media and is ideally suited for the hazardous environment present in mines.1. INTRODUCTIONIn the recent past, much attention has been given towards the development of fiber optic sensors. The fiber optic technology has emerged as one of the fastest expanding technologies and its application has been realized in almost all the disciplines of transduction. In an underground coal mine, continuous monitoring of methane gas is very important because methane-air-mixture is highly explosive between 5-14.5%. Currently catalytic bead type methane sensors are used for the detection of methane gas in the range of 1-5%. Recently several workers have developed fiber optic methane sensors for mines based on different techniques [1-5]. Steel ropes are used in different hoisting system of mines and degradations are found by virtue of its environmental conditions. Pre-mature failure of wire rope may cause heavy damage of men and machineries both. Therefore, it is essential to have a continuous monitoring system for the wear and tear of steel ropes. Traditionally, the conditions of these steel ropes are monitored by visual inspection or by electromagnetic inspection (non-destructive testing NDT) at certain periodic intervals. To the best of our knowledge there is no system yet available for continuous health monitoring of hoisting system ropes. Recently fiber Bragg grating (FBG) sensors systems have been widely used for strain measurement in several fields such as surveillance of bridges, tunnels and mines [6-8]. The author has also explored the various possible applications of fiber optic sensors in mines [9-12]. In this paper, a brief description of evanescent wave fiber optic methane and FBG based strain sensors has been given. The laboratory model of methane sensor has been designed and developed at ISM, Dhanbad. However, the strain has been designed jointly with ISM, Dhanbad and CSIO, Chandigarh[11].2.EVANESCENT W AVE FIBER OPTIC METHANE SENSORThe experimental set up of evanescent wave fiber optic methane sensor is shown in Fig 1. In this experiment a cylindrical glass tube of 0.6 m length has been typically designed with both ends open. This tube acts as gas cell or gas chamber for the sensor. Two small windows, W1 and W2, have been provided with the tube for gas inlet and outlet near the ends. The plastic clad silica (PCS) fiber of 1 m length with 600 μ m core-diameter has been taken and approximately 50 cm length of plastic cladding has been removed from one side. This fiber has been passed through the tube carefully so that uncladportion of the fiber lies inside the tube. Some workers have used specially designed D-shaped [13, 14] fiber for detecting methane gas at 1.33 μm wavelength. In the present work we have detected the overtone weak peak of methane gas at 1.33μm. Glass tube has been sealed at both the ends. One end of the PCS fiber has been connected with the laser source of 1310 ±20 nm wave length, -10dBm adjustable power and 5 nm spectral widths and another end has been connected with power meter. Methane gas has been passed through the glass tube using aspirator. The output power (Po) for three different concentrations, i.e., 2.5%, 5% and 10% of CH4 gas has been recorded. Figure 2 shows the plot between the methane concentration and 1/PN, where PN (= P0/P) is the normalized transmitted power; P0 and P are the fiber transmittance in the absence and presence of the absorbing gas, respectively. A linear relation has been obtained between them. The curve shown in Fig. 2 can be considered as a calibration curve for methane sensor. Any unknown concentration between。
