自动浇水花盆作文英文回答:Self-watering planters are a type of container that allows plants to access water as needed, without the need for manual watering. They typically have a reservoir that holds water, and a wick or other absorbent material that draws water up to the plant's roots. This type of planteris particularly useful for people who are away from homefor extended periods of time, or who have difficulty watering their plants regularly.There are many different types of self-watering planters available, each with its own advantages and disadvantages. Some planters have a built-in reservoir, while others require the use of a separate container. Some planters have a wick or other absorbent material that draws water up to the plant's roots, while others use a capillary action to draw water up through the soil.When choosing a self-watering planter, it is important to consider the size of the plant, the type of soil, and the amount of water the plant needs. It is also important to consider the environment in which the planter will be used, and the amount of maintenance that is required.Self-watering planters can be a great way to keep plants healthy and hydrated, even when you are away from home. They can also be a good way to save water, and to reduce the amount of time you spend watering your plants.中文回答:自动浇水花盆是一种允许植物在需要时获取水分的容器,无需手动浇水。

DRIP IRRIGATION AUTOMATION WITH AWATER LEVEL SENSING SYSTEM IN A GREENHOUSEAutomated control systems in irrigation have in recent years made considerable progress, offering a wide range of new options. In this experiment, drip irrigation system automatically governed irrigation in accordance with a water level sensing system in the mini-pan with the help o f evaporation. Data acquisition was performed by an electronic circuit, which processed data and then sent the data to the microcontroller (Pic16f877). In the system, a closed loop control system based on sensing water level in the mini-pan was used to activate irrigation, thereby the system started irrigation whenever water level in the mini-pan dropped to the set level. The performance of the automated system can be increased as the irrigation timing in the software is adjusted according to plant growth stages.Keywords: automated irrigation; drip irrigation; water level sensor; irrigation controller; mini-pan.INTRODUCTIONPressurized irrigation systems when combining by an automation systems have become more effective in irrigation practices. Nowadays, the current trend has been swithcing from a manual system to automatic operations in a pressurized system and also that automation and electronics in agriculture become more popular all around the world (Josi and Gokhale, 2006). Energy savings, reduced labor cost and control in fertilizer application are among some of the major advantages in adopting auotomated techniques in drip irrigation systems (Yildirim and Demirel, 2011). Automated irrigation systems provide high crop yield, save water usage(Mulas ,1986), facilitate high frequency and low volume irrigation (Abraham et al. 2000), and also reduce human errors (Castanon, 1992). Many methods have been described and sensors developed to manage irrigation systems objectively (Salas and Urrestarazu, 2001). Recent irrigation technologies have used sophisticated equipment to supply water to the root area of plants as they need it. However, the use of these sophisticated methods is not possible for all growers. A simple irrigation system, called the irrigation control tray, was developed by Caceres et al. (2007), which activated the irrigation system with the aid of a level-control relay. Gieling (1995) stated that automation systems should be used both to measure the environmental conditions and to use in irrigation. Irrigation can be performed according to the methods of solar radiation and Class-A pan. Class-A pan has been used succesfully in all over the world to estimate evapotranspiration. Hanan (1990) reported that Class-A pan used in an greenhouse to estimate evapotranspiration has achieved the similar results as musch as the methods of radiation (FAO) and Priestley- Taylor. Jain (1975) and Sharma et al. (1975) stated Class- A pan is not appropriate for farmers to be used in an open field, so that they used a mini-pan(10.5 cm in diameter and 13.5 cm in height) to irrigate wheat and maize in an open field and obtained the correlation coefficient of 0.82 between mini-pan and Class-A pan. Palacios and Quevedo (1996) used a mini-pan consisting of double ring (the inner ring was 27.5 cm in diameter and 7.5 cm in height, the outer ring 55 cm in diameter and 22 cm in height) to schedule the irrigation program in an open field and reported to be used for irrigation. Cemek et al.(2004) observed a strong relationship between mini-pan and Class-A pan.The objective of this study was to test a prototype of a mini-pan and a water level sensor and also to modify the irrigation controller, triggered by the water level sensor in the pan, and thereby develop a simple and economical automated irrigation system appropriate for greenhouse growing of high-value crops. MATERIALS AND METHODSThe experiment was conducted outdoor of a greenhouse from May to August, 2011 at Canakkale Onsekiz Mart University, Turkey. The geographical location of the experimental area is 40°06'32.64'' N latitude, 26°24'45.31'' E longtitude, and has a 5-m elevation (Figure 1).Temperature (o C) and relative humidity (%) at the site were measured 1.5 m above the canopy of the plants by using a HOBO U12 instrument (Figure 2), and measurement range was from -20 0C to 70 0C for temperature, 5% to 95% for humidity.The quality of the irrigation water is given in table 1. A standard soil must have a pH value between 6.5 and 7.2 and electrical conductivity (EC) of less than 4 mS cm-1 (Ayers and Westcot, 1994). According to these values, the salinity level of the substrate was in the normal range. The irrigation water, however, was in the moderately tolerable range; it had already been used for irrigation at the site. Each pot in the experiment was applied with the same amount of fertilizers: triple super phosphate (3 g per pot), potassium sulfate (3 g per pot) and urea (3 g per pot). Urea was applied again at 15 and 20 day intervals respectively after planting at the same dosage.Components of the automated irrigation system: Nurseries planted with peppers (Capsicum annuum L.) were transplanted into pots. The substrate was a mixture of peat (1:4, v/v) and soil (3:4, v/v).), each pot contained 4L of substrate and the layout of the experiment's components is given in figure 3. The irrigation system included the following components; water storage tank (50 L); one of it was to irrigate , another one was to fill the mini-pan, submersible pump operating at 12 vdc(volts direct current) in each storage tank and 2.05A, power supply (12 vdc), pots (250x210 mm, 9 L) having a pan under it to collect water that drains, Ø16 pipes with drippers (4 L/h) at a spacing of 33 cm, with one dripper serving each pot. Valves and connection apparatus were used to integrate all items of the irrigation system.Minipan was consisting of double rings, the height of both was 20 cm, the inner ring diameter of 27 cm and the outer of 32 cm, also there was a notch at the bottom of inner ring providing water movement between them. The sensor determining the amount of allowable water to evaporate was installed inside in the inner ring. The top tube was welded to the upper point of the mini-pan to fill it and water was pumped by the irrigation controller from storage tank, when the allowable amount of water was evaporated from mini-pan. The drainage pipe was removing excess water to fix the top water level in the mini-pan to 13.5 cm after each filling process as seen figure 4.The most important and basic component of the automated irrigation system was the sensor, which detected the water level in the mini-pan. It was made of two steel rods, one rod fixed and screw one was moving up and down to adjust the amount of water allowed to evaporate. The distance between the rods was 2.5 cm. They were placed in a plastic box (width 3x3 cm, height 1 cm), then filled with silicone. At the end of the rods, the cable was connected to provide an electrical communication between the rods and the MCU (Fig. 5).A signal coming from the water level sensor was sent to the Microcontroller unit (MCU-Pic16F877) and then irrigation started and stopped according to the logic embedded in MCU. The circuit included both a buzzer to give a warning voice and an LCD to show some messages such as "1.pump run" or "2.pump run" etc. The MCU unit is a device that has programmable capability, read sensor, and controls the devices such as relays connected to the pumps( fig 3). In this experiment, the MCU was actually a controller, upon receiving a signal from the water level sensor it runs the pumps and shuts down after the procedure. The MCU has a 20 Mhz pic processor with 40-pin Dual In-line package (DIP) and runs at a relatively low voltage value of 5 vdc (Altınbasak, 2004). One pin of the MCU was assigned as an input to monitor the water level in the mini-pan in each second for all day and throughout the entire experiment. Even though circuit has 4 relays, two pins of the MCU were assigned as output pins both to pump water to the root area of the plants and to pump water to fill the mini-pan.Controller software: The irrigation controller program was written using the PicBasic Pro software program and the general strategy for the automated irrigation defined in the logic was loaded into the memory of the MCU. Hence, the logic of the irrigation strategy was defined in the MCU, having a memory of 2K, which then took over and made detailed decisions on when to apply water and how much water to apply. The dosage of water to be applied was determined according to the pumping time of water to refill the root zone as water level in the mini-pan dropped the threshold level. In the system, the feedback and control were done constantly, depending on the feedback from the sensor. Whenever a signal was sent to the MCU, the irrigation actions were carried out during the whole experiment period. Data flow diagram in the software is given in figure 6. The top water level in the mini-pan was 13.5 cm, and a signal was produced whenever the level dropped to 12 cm, thenthe MCU started irrigation and first, ran the irrigation pump for 15 minutes and second, filled the mini-pan. After completing these processes, it checked whether the mini-pan full or not. if yes, it went to back to read the sensor. If not, it sent the message "the system is out of order, please check" on LCD (Fig. 6).Irrigation applications: The irrigation treatments were arranged as follows: the required time (15 minutes) for pumping water to the root area of the plant as 30% of available soil moisture was depleted was the time required to raise moisture content of the substrate up to field capacity (FC) in each irrigation. After each irrigation, all pots were weighed manually, then the water quantities were determined by weight of the pots intended to identify evapotranspiration. Daily evapotranspiration (ET) was estimated by using the water balance method between the two irrigations(Yıldırım and Demirel, 2011).ET= [((Wi-1 -- Wi) + I -- D) / A ] i =1,2,3,…n ( 1)Where: ET is the evapotranspiration (mm), Wi-1 and Wi mass (kg) of the pot at day i-1 and i, respectively, I is the amount of irrigation water (kg), D is the quantity of the drainage water if available (kg), and A is the pot surface area (m2).Plant and fruit development parameters were observed for each plant in the treatment. Weights in gram for stem, leaf, etc. were determined by using a sensitive weighing (0.01g).RESULTS AND DISCUSSIONFruit development and vegetative growth parameters were given in table 2. Even though mean fruit weight was similar to the literature, stem and leaf weight and leaf area of pepper were slightly lower than the values given for these by Yildirim (2010) and Yildirim and Demirel (2011). The action of root zone depletion and the timing of the irrigation events throughout the calendar days are shown in figure 7. The irrigation events were performed successfully between 165 and 184 days of the year as seen in fig 7, since the MCU activated the pumps whenever water level dropped to 12 cm in the mini-pan. The controller unit, however, couldn't activate the pumps on the 185th, 195th, 212nd calendar days, even water level was below 12 cm. The reason of that was an adhesion of a small piece of straw to the adjustable rod, providing a connection between water and rod. That's why, the sensor failed to produce a signal to be sent to the MCU. However, after removing the straw, the system has fulfilled its responsibilities successfully. Therefore, the average pot weights dropped up to 5146 g on the 185th day of the year.Water was applied according to the pre-set strategy by the automated system whenever water level in the mini-pan dropped to 12 cm, and the system met the water demand of plants till 185th day of the year. However, irrigation couldn't be initiated by the system on the 185th day, even though water level in the mini-panfell up to 11 cm and soil moisture level in the substrate dropped up to 5146 g also. By taking the straw away from the mini-pan, the MCU initiated irrigation and brought the pots to the weight of 6200 g and increased the water level to 13.5 cm in the mini-pan. Because of the high evaporation in July, the water in the mini-pan that allowed to evaporate was adjusted from 15 mm to 10 mm by the screw rod and irrigation started when evaporation occurs 10 mm after the calendar day of 188th . Evaporation amounts and days on when irrigation events were activated are given in figure 8. As seen in fig 8, the system performed irrigation activities successfully according to the identified strategy, since the water level in the mini pan was increased to 13.5 cm at regular intervals and this time irrigation was activated when the water level fell to 12.5 cm. The substrate moisture level in the substrate after and before irrigation is given in figure 8. Even though the system run successfully according to the identified strategy, the substrate moisture level in plant roots remained below 6000 g which was caused by the definitions of the fixed run time of the irrigation pump to the MCU, as 15 minutes. The moisture level after and before irrigation seems to parallel to each other in fig 9. It is obvious that the moisture level in the substrate started decreasing in a stepwise manner after the 185 days of the year. Stress development in pepper plants began at this time and reached to the top level on the 199 days of the year due to the lack of water of 200 g. if irrigation timing was increased in a step manner from 15 minutes to 21 minutes after 185 days of the year up to the 199 days of the year, the performance of the system would be very higher than the existing conditionThe relationships between the Class-A pan and mini-pan were given in figure 10. The amounts of evaporation in Class-A pan from June to August were 159.9, 294.1 and 61.5 mm, respectively, but those of that in the mini-pan reduced to 88.8, 127.6 and 27 mm for same months, respectively. Therefore, the correlation coefficient between Class-A pan and mini-pan were r2=0.50, which was lower than the values given in the literature. The main reason of less evaporation in the mini-pan was to place it next to the plants, which caused a reduction in the amount of evaporation by shading the mini-pan.Cemek et al. (2004) identified the correlation coefficient of evaporation occurring Class-A pan and mini-pan as 0.81. Palacios and Quevedo (1996) reported thatmini-pan can be used in irrigation scheduling. Jain (1975) and Sharma et al. (1975) found the correlation coefficient between Class-A pan and mini-pan as 0.82, and they used a mini-pan successfully in corn and wheat irrigation in open field.The prototype of the irrigation controller was tested to determine both the controller unit, sensor and software performances. In this experiment, once the general strategy was defined by the MCU, it took over and made decisions about when to apply water and how much water to apply. Yildirim and Demirel (2011) developed an irrigation controller and reported that the most important points in the automated drip irrigation system are sensor calibration and installation of the soil moisture sensor in the pot. In the experiment, depending on the feedback of thewater level sensor, the irrigation decision was made and actions were carried out throughout the entire experiment. However, plant development parameters were lower than the values given in the literature, since the irrigation timing in the software used in the experiment was simple. Therefore, irrigation timing should be defined into algorithm according to the plant growth period and the location of the mini-pan is so important, since evaporation is greatly affected when it has been under the shadow of pepper plants and doesn't reflect the evapotranspiration. When this system is used in a greenhouse, irrigation timing must be arranged according to the plant growth periods.Acknowledgements: The author is grateful for the financing of the study to Scientific Support Program of Canakkale Onsekiz Mart University in Turkey, Research Project Reference No: BAP (2011-45).

本科毕业设计(外文翻译)题目自动浇花系统的设计姓名刘富强专业自动化学号201042048 指导教师赵明冬郑州科技学院电气工程学院二○一四年五月New Environment Parameters Monitoring AndControl System For Greenhouse Based OnMaster-slave DistributedAbstractAccording to the actual need of monitoring and control of greenhouse environment parameters in rural areas,a master-slave distributed measurement and control system is designed,in which PC is taken as the host. The system consists of PC ,soil moisture measurement and control module,temperature and humidity, and CO2 monitoring and control module. In the system,PC has large amount of data storage which is easy to make use of fuzzy control expert system,configuration software-KingView is used to develop software for PC,by which the development cycle is shorten and a friendly human-computer interaction is provided.Each monitoring and control module consists of STC12 series of microcontrollers,sensors,relays etc.Different modules are select based on the need if system to achieve control greenhouse in partition and block.I INTRODUCTIONTo modern indoor agriculture, the automatic measurement and control of environment parameters is the key to achieve crop yield and quality of greenhouse.In recent years,facilities agriculture develops vigorously in our country,matched with it,the monitoring and control instrument of greenhouse have also made certain development.After nearly 10 years of unremitting hard work,our research team of measurement and control system of agriculture environment parameters,designed an intelligent measurement and control system of distribution combined of greenhouse which can be popularized in the vast rural areas.This system is mainly control of temperature,humidity,CO2 concentration,soil moisture and illumination of greenhouse.OF SCM,as the data storage is small,display interface is single,amount of information is limited,but its capability price ratio is high,so it is used as a front unit of data acquisition and control;and of PC,it has a large amount of data storage,rich software,convenient human-computer interaction,and so on.If we use outdated and low-priced PC,taking the PC as the upper machine,taking the different function control modules composed of multiple microcomputers as the lower machines,then a master-slave distributed and intelligent control system bases on microcomputer is made up,by which both better monitoring and control,display and data collection or management are achieved,but also lower cost of system is get according to the actual need.II SYSTEM STRUCTURE AND PRINCIPLEThe most marked feature of the distribution combined and intelligent control system greenhouse is that of incorporating with data acquisition, control and management as a whole,module combination, simple structure,convenient human-computer interaction,and using technology of intelligent expert fuzzy control,which can adapt to a variety of crop management control in greenhouse.The basic structure of the system is shown in Fig.1.The structure of the distributed system is composed of two layers:the upper and lower.In the top-price PC is taken as the host to make system management and experts fuzzy operation in intelligent,and to provide a friendly human-computer interface,and to realize the united monitoring and management of greenhouse; the lower is composed of a series of modules of different function,and in each module,a single chip of AT89Cis adopted as the lower machine,RS485 is used to communicate PC with all AT89C,and then the collection,processing and control of the greenhouse parameters is achieved.Each function module is completely isolated in electrical,any failure on the nodule does not produce any effect on other modules.The system collects separately ways of environment information through each monitoring and control module,and sends it to host PC through the RS485 interface.And in the PC configuration control system,the acquired parameters are compared with the values of setting,then according to a variety of expert intelligent fuzzy control system of crops at different growth stages,the fuzzy control instructions on the environment temperature,humidity,CO2 concentration,soil water content and the corresponding operation instructions or alarm are given.The system is applied in rural greenhouses in ually at 1/4 near East and West end in a greenhouse,and at the height of 1.5m from the ground in the middle in the northern half (near the wet curtain) and the southern half (near the fan ),a module of air temperature and humidity ,CO2 concentration and a module of soil moisture content are set;a module of soil moisture content will be added in the middle of the greenhouse according to the actual condition;at the height of 1.5m in the main entrance,a water tank is set,of which the solenoid of drip tube should be set based on the need and controlled by module of soil moisture content;and the PC is placed in the main entrance to thegreenhouse.III HARDWARE DESIGNA.The CP and communication systemIn the distributed system of data acquisition and control,as the micro control unit is limited in data storage and slow in calculating of complex functions,so PC is used and the master-slave module is adopted in the system,that is a system of,taking PC as the host and taking the SCM systems located in the scene as slave.In this distributed system,communication is the key to it.Generally,the serial port of PC is standard RS232,of which transmission distance is shorter.But in agriculture control system.its communication distance is of tens of meters or several kilometers, so RS232/RS485 converter is used to achieve communication between the PC and SCM.To reduce investment,both considering the user convenience and friendly human-computer interaction,low-price PC of above 486 and below PIV is adopted;and considering the operation of configuration software,it is required that memory is 64M or above and hard disk is 10Gb or above.B. The control modules of temperature and humidity,illuminance and CO2 concentrationEach control unit consists of SCM,sensors,signal processing circuit,RS485 interface and output circuit.The hardware structure ofmodule of temperature and humidity,CO2 concentration is shown in Fig.2.CO2 concentration is measured by sensor based on NDIR technology,measurement is of 0~2×103mol.Through the sensor,control system,by software of digital filter,linear interpolation and temperature compensation,the CO2 concentration is output as digital adhered to UART protocol,and then is input directly to the SCM.The new intelligent sensor of SHT11 based on CMOSens technology is chosen in the measurement of temperature and humidity.In SHT11,the temperature and humidity sensors,signal amplification,A/D,I2C bus are all integrated in a chip;it has full-scale calibration,second-line digital output,and humidity measuring range of 0~100% RH,temperature measurement range of -40℃~+123.8℃,humidity measurement accuracy of ±3.0% RH,temperature measurement accuracy of ±0.4℃,the response time of <4s.The illuminance sensor of JY1-TBQ-6 of silicon photovoltaicdetection is used Light measuring.Its measurement range is 0~200,000 Lux;spectral range is 400~700(nm) visible light;measurement error is less than 2%; output is 4~20mA or 0~20mV;output signal can be directly send to the A/D of the SCM after being amplified to 0~4V.Modules accept the instructions form the the Upper,and output via the output circuit .The output circuit consists of optical isolation,the signal driver and the output relays.C. The measurement and control modules of soil moistureWater is a polar medium, the dielectric constant of the soil containing water is mainly determined by the water,when water content is different,the wave impedance is different.The soil moisture is measured by standing wave radio method in this system.Based on the theory of Engineering Electromagnetic Field,for lossy medium,the electromagnetic wave impedance as follows:Z0=√μ/ε(1+jλ/(ωε))Where μ is medium permeability,and μ of soil is μ≈μ0 is the vacuum permeabil ity;ε is medium dielectric constant;λ is medium conductivity;ω is electromagnetic wave frequency.In the very low audio(<2000Hz),the loss tangent of dry soil dielectric is λ/ωε≈0.07,if you choose the frequency of the signal source at above 20MHz.then,ε≈ε∞,the imaginary part of the soil wave impedance is neglect,only the real part,which amounts to a pure resistance.Soil moisture sensor consists of 100MHz signal source,a coaxial transmission line and a 4-pin stainless probe.The electromagnetic waves of signal transmit to the probe along the lines.As the probe impedance and line impedance are different,the superimposition of incident waves and reflected waves forms a standing waves.Taking the coaxial transmission line as a lossless uniform line,wave impedance is Z0,Z l is the load impedance.Then the reflected coefficient of voltage wave at the probe is:Γ=(Z L-Z0)/(Z L+Z0)Choosing the length of transmission line is l=λ/4,the maximum and minimum of both ends of the line are U max and U min,Then the standing wave radio in the line can be expressed as:S=U max /U min =(1-|Γ|)/(1+|Γ|)In the way,the soil moisture radio can be measured by measuring the standing wave rate of transmission line.As shown in Fig.3.,soil moisture module consists of sensors and controllers,the sensors are subordinated to controllers,controllers can be omitted without the need of irrigation in greenhouse.To simplify the control,irrigation technology of node-type in partition is adopted in the control soil moisture in this system.To a certain extent,the parameters of upper and lower the ground can be decoupled by adopting this technology.IV CONTROL SYSTEM PROGRAMMINGThe software of PC is developed by KingView 6.51 of Beijing-controlled Asia.This configuration software has high reliability,shorter development cycle,perfect capability of graphical interface generation,and friendly human-computer interaction;and can create dynamic images and charts in accordance with the layout of equipment in the scene;can visually display the changes of parameters,control status,and can give an alarm when over-limited;and can achieve fuzzy control of greenhouse parameters by using the history curve of environment parameters stored in the specific database and adopting the agricultural expert system.The software of SCM of the slave is developed by Keil C51 to achieve real-time collecting,processing,uploading of the parameters and accept the fuzzy control instructions from the host computer and complete local control of the device.A.Program design of the control moduleThe software of the sub-slave machine of soil moisture module,that include the main function,subroutines of data acquisition and processing,interrupt handling and communicating etc,read the value of standing wave voltage through the parallel data port and obtained the value of soil moisture content by function calculating.The software of the slave machine of monitoring and control of soil moisture mainly complete data communication with the sub-slave machine,uploading measurement data and current control state to the host computer,accepting the fuzzy control instructions from the host computer and output the implementation instructions.The software of the slave machine of temperature and humidity,and CO2 mainly complete reading data of CO2 concentrations and temperature and humidity through the I2C concentration,uploading measurement data and current control state to the host computer,accepting the fuzzy control instructions from the host computer and output the implementation instructions.The structure of the main program and interrupt subroutine of temperature and humidity module are shown in Fig.4.The serial interrupt mode 3 is adopted by all slaves to communicate with the host,transmit the digital collecting and receive instructions.B. Program design of PC and fuzzy control system1)The communication settings of KingView 6.51:In order to ensurethe correctness of communication,the upper and lower must follow the same communication protocol,set the communication ually in communication,master-slave mode is adopted in style and responder is adopted in the process.That is ,the master sent a command to the slave first,then et slave give an answer after receiving the command,thus once communication is completed.In KingView ,a scheduled polling method is adopted to do reading and writing between the lower machine by PC.In the project browser of KingView,first,click device →COM1;in the wizard of device configuration,select intelligent modules→SCM→current SCM of HEX→serial port,and then ser parameters for the host computer’s communication.2)The connection of KingView 6.51 and database:Database is the core of the software,that not only contains the definition of variables,real-time parameters and the historical parameters,but also is needed by parameters alarming,fuzzy calculating,reporting ,and displaying.Access2003 desktop database is used as records database of the system,and by using SQL,it is operated by KingView via ODBC.The procedure is :to create data variables in KingView to create a body of records to establish a data source of ODBC to create query screens and make the screen connection.To connected with Microsoft Access2003,the functions of SQLConnect(),SQLSelect(),SQLLast(),SQLNext(),SQLFist(),SQLPrew(),SQLInsrt(),and so on,should be implemented in the command language,and then real-time storage and inquiry of data are completed.3)Software design of PC :For the control system of greenhouse,data storage capacity of the PC is unlimited,so if the existing mature software modules are include into the system,it both be relaxed and can improve the system reliability.The software of software consists of control module and management module.V CONCLUSIONAccording to the economic bearing capacity of farmer in Qinhuangdao ,with the existing technology of monitoring and control of environment parameters of greenhouse,a master-slave distributed automatic control system of greenhouse environment in which PC is taken as the host computer is developed.The system has following characteristics:1)With the large amount of data storage of PC,fuzzy control expert system is easy of data storage,modification and system upgrading.2)By using KingView to develop software of PC,the system reliability is improved,and the development cycle is shorten,and a friendly human-computer interface is get.3)A distributed and modular structure is used in the system,it makes the system maintenance easier and adapts to production needs more. The monitoring and control modules of the slave are connectedto the host through the RS485 bus based on needs,then the control of greenhouse in partition or block can be achieved.基于新的温室环境参数监测和控制系统根据实际在农村地区的温室环境参数的监测和控制,主从分布式测量和控制系统的设计需要,以其中一台计算机作为主机,该系统由PC、土壤水分测量和控制模块,温度、湿度、CO2监测和控制模块组成。

1 introduction
With the social modernization step speeding up, automation has become a development topics in today's world. Flower's growth needs to have certain environmental conditions, these conditions are mainly temperature, moisture, illumination, air composition, composition, physical and mechanical properties of soil and nutrient solution temperature and composition, etc. Flowers can be a good growth is most important of which is the suitability for soil moisture. How to control soil moisture effectively and timely problem has already become the flowers AiHuaZhe most issue of concern. Flower proverbs said: "don't live in the water, long is fat".

Flower's growth needs to have certain environmental conditions, these conditions are mainly temperature, moisture, illumination, air composition, composition, physical and mechanical properties of soil and nutrient solution temperature and composition, etc. Flowers can be a good growth is most important of which is the suitability for soil moisture. How to control soil moisture effectively and timely problem has already become the flowers AiHuaZhe most issue of concern. Flower proverbs said: "don't live in the water, long is fat". Potted flowers and plants due to the volume small, poor water retention performance, large evaporation nor groundwater supply limited by certain conditions, such as the reason, not to drought, water is particularly important. If potted flower water, plant physiological activities will damage in the body, the absorption of potassium, boron, calcium phosphate is weak, and the lack of these elements can lead to poor growing point nearby growth. Potted flower water shortage will cause soil nutrient concentrations are relatively high, also appear the most easily hurt "fat" [. Flowers grow, most come from the soil absorption, keep soil moisture content, appropriate is the normal development of flowers and necessary conditions to obtain higher GuanShangPin qualitative. Common flowers according to the water requirement of habits and the different water environment adaptability, can be divided into aquatic flowers and plants, wet flowers, flowers and xerophytic flowers in four. The amount of water in different we need to water the flowers are not the same as [3]. Different flower water demand is different, the same flower in different growth stage required quantity is also different. Flowers requirement for soil water varies in each growth stage. We according to the growing season and growth periodof flower arrange . To sum up, the reasonable water potted flower is particularly important. With the constant improvement of automation equipment, all kinds of automatic watering the flowers device also from time to time into the society. According to soil moisture sensor design of automatic watering flowers system can according to crops and different growth stages to the specific needs of environmental conditions, adjust to control soil moisture flowers, let the flower can grow well.2 automatic watering technique3.1 based on PC technology research with the development of computer technology with each passing day, the PC can not only used in scientific computing, data processing, etc., are widely used in industrial production of automatic control, automatic watering flowers requires real-time detection of soil moisture. "Real time" refers to the timely response to a random request of external events, and fast enough to complete the processing of external events, real-time control of all equipment and real-time tasks coordinated operation . The main characteristics of the real-time system is real-time and reliability. With the constant improvement of the PC performance and reliability, PC machine widely used in real-time systems, and the current general operating system based on PC (such as WINDOW S systems) do not have good real-time performance, can not satisfy most timing indicator of real-time systems.

It also allows for precise control over the amount of water each plant receives, ensuring that they get just the right amount of moisture they need. Additionally, drip irrigation systems can be automated, saving gardeners time and effort.Another way to improve the watering system is by usinga soaker hose. Similar to drip irrigation, a soaker hose delivers water directly to the base of the plants. It is a cost-effective and efficient way to water plants, as it reduces water runoff and evaporation. Soaker hoses are also easy to install and can be used in various garden settings, from vegetable gardens to flower beds.In addition to these advanced watering systems, there are also simple yet effective ways to improve thetraditional watering methods. For example, using a watering can with a narrow spout allows for precise watering, ensuring that the water reaches the roots of the plants without splashing onto the leaves. This helps to prevent diseases and fungal growth, which can occur when thefoliage remains wet for extended periods.Furthermore, mulching the soil is another effective way to improve the watering system. Mulch helps to retain moisture in the soil, reducing the frequency of watering and preventing water loss through evaporation. It also helps to regulate soil temperature, suppress weeds, and improve the overall health of the plants.By improving the watering system, gardeners can enjoy a range of benefits. Firstly, it saves time and effort, as advanced watering systems can be automated and require less manual labor. This allows gardeners to focus on other aspects of gardening, such as planting, pruning, and harvesting. Secondly, it conserves water, as advanced watering systems are designed to minimize water waste and evaporation. This is not only beneficial for the environment but also helps to reduce water bills for gardeners. Lastly, it promotes healthier plants, as precise watering and soil moisture control contribute to theoverall well-being of the plants.In conclusion, improving the watering system is essential for efficient and effective gardening. Whether it is through the installation of advanced watering systems like drip irrigation and soaker hoses, or through simple yet effective methods like using a watering can with a narrow spout and mulching the soil, there are various ways to enhance the way we water our plants. By doing so, gardeners can save time and effort, conserve water, andpromote healthier plants, ultimately leading to a more successful and enjoyable gardening experience.。

本科毕业设计(外文翻译)题目自动浇花系统的设计姓名刘富强专业自动化学号*********指导教师赵明冬郑州科技学院电气工程学院二○一四年五月New Environment Parameters Monitoring AndControl System For Greenhouse Based OnMaster-slave DistributedAbstractAccording to the actual need of monitoring and control of greenhouse environment parameters in rural areas,a master-slave distributed measurement and control system is designed,in which PC is taken as the host. The system consists of PC ,soil moisture measurement and control module,temperature and humidity, and CO2 monitoring and control module. In the system,PC has large amount of data storage which is easy to make use of fuzzy control expert system,configuration software-KingView is used to develop software for PC,by which the development cycle is shorten and a friendly human-computer interaction is provided.Each monitoring and control module consists of STC12 series of microcontrollers,sensors,relays etc.Different modules are select based on the need if system to achieve control greenhouse in partition and block.I INTRODUCTIONTo modern indoor agriculture, the automatic measurement and control of environment parameters is the key to achieve crop yield and quality of greenhouse.In recent years,facilities agriculture develops vigorously in our country,matched with it,the monitoring and control instrument of greenhouse have also made certain development.After nearly 10 years of unremitting hard work,our research team of measurement and control system of agriculture environment parameters,designed an intelligent measurement and control system of distribution combined of greenhouse which can be popularized in the vast rural areas.This system is mainly control of temperature,humidity,CO2 concentration,soil moisture and illumination of greenhouse.OF SCM,as the data storage is small,display interface is single,amount of information is limited,but its capability price ratio is high,so it is used as a front unit of data acquisition and control;and of PC,it has a large amount of data storage,rich software,convenient human-computer interaction,and so on.If we use outdated and low-priced PC,taking the PC as the upper machine,taking the different function control modules composed of multiple microcomputers as the lower machines,then a master-slave distributed and intelligent control system bases on microcomputer is made up,by which both better monitoring and control,display and data collection or management are achieved,but also lower cost of system is get according to the actual need.II SYSTEM STRUCTURE AND PRINCIPLEThe most marked feature of the distribution combined and intelligent control system greenhouse is that of incorporating with data acquisition, control and management as a whole,module combination, simple structure,convenient human-computer interaction,and using technology of intelligent expert fuzzy control,which can adapt to a variety of crop management control in greenhouse.The basic structure of the system is shown in Fig.1.The structure of the distributed system is composed of two layers:the upper and lower.In the top-price PC is taken as the host to make system management and experts fuzzy operation in intelligent,and to provide a friendly human-computer interface,and torealize the united monitoring and management of greenhouse; the lower is composed of a series of modules of different function,and in each module,a single chip of AT89C is adopted as the lower machine,RS485 is used to communicate PC with all AT89C,and then the collection,processing and control of the greenhouse parameters is achieved.Each function module is completely isolated in electrical,any failure on the nodule does not produce any effect on other modules.The system collects separately ways of environment information through each monitoring and control module,and sends it to host PC through the RS485 interface.And in the PC configuration control system,the acquired parameters are compared with the values of setting,then according to a variety of expert intelligent fuzzy control system of crops at different growth stages,the fuzzy control instructions on the environment temperature,humidity,CO2 concentration,soil water content and the corresponding operation instructions or alarm are given.The system is applied in rural greenhouses in ually at 1/4 near East and West end in a greenhouse,and at the height of 1.5m from the ground in the middle in the northern half (near the wet curtain) and the southern half (near the fan ),a module of air temperature and humidity ,CO2 concentration and a module of soil moisture content are set;a module of soil moisture content will be added in the middle of the greenhouse according to the actual condition;at the height of 1.5m inthe main entrance,a water tank is set,of which the solenoid of drip tube should be set based on the need and controlled by module of soil moisture content;and the PC is placed in the main entrance to the greenhouse.III HARDWARE DESIGNA.The CP and communication systemIn the distributed system of data acquisition and control,as the micro control unit is limited in data storage and slow in calculating of complex functions,so PC is used and the master-slave module is adopted in the system,that is a system of,taking PC as the host and taking the SCM systems located in the scene as slave.In this distributed system,communication is the key to it.Generally,the serial port of PC is standard RS232,of which transmission distance is shorter.But in agriculture control system.its communication distance is of tens of meters or several kilometers, so RS232/RS485 converter is used to achieve communication between the PC and SCM.To reduce investment,both considering the user convenience and friendly human-computer interaction,low-price PC of above 486 and below PIV is adopted;and considering the operation of configuration software,it is required that memory is 64M or above and hard disk is 10Gb or above.B. The control modules of temperature and humidity,illuminanceand CO2 concentrationEach control unit consists ofSCM,sensors,signal processing circuit,RS485 interface and output circuit.The hardware structure of module of temperature and humidity,CO2 concentration is shown in Fig.2.CO2 concentration is measured by sensor based on NDIR technology,measurement is of 0~2×103mol.Through the sensor,controlsystem,by software of digital filter,linear interpolation and temperature compensation,the CO2 concentration is output as digital adhered to UART protocol,and then is input directly to the SCM.The new intelligent sensor of SHT11 based on CMOSens technology is chosen in the measurement of temperature and humidity.In SHT11,the temperature and humidity sensors,signal amplification,A/D,I2C bus are all integrated in a chip;it has full-scale calibration,second-line digital output,and humidity measuring range of 0~100% RH,temperature measurement range of -40℃~+123.8℃,humidity measurement accuracy of ±3.0% RH,temperature measurement accuracy of ±0.4℃,the response time of <4s.The illuminance sensor of JY1-TBQ-6 of silicon photovoltaic detection is used Light measuring.Its measurement range is 0~200,000 Lux;spectral range is 400~700(nm) visible light;measurement error is less than 2%; output is 4~20mA or 0~20mV;output signal can be directly send to the A/D of the SCM after being amplified to 0~4V.Modules accept the instructions form the the Upper,and output via the output circuit .The output circuit consists of optical isolation,the signal driver and the output relays.C. The measurement and control modules of soil moistureWater is a polar medium, the dielectric constant of the soil containing water is mainly determined by the water,when water contentis different,the wave impedance is different.The soil moisture is measured by standing wave radio method in this system.Based on the theory of Engineering Electromagnetic Field,for lossy medium,the electromagnetic wave impedance as follows:Z0=√μ/ε(1+jλ/(ωε))Where μ is medium permeability,and μ of soil is μ≈μ0 is the vacuum permeability;ε is medium dielectric constant;λ is medium conductivity;ωis electromagnetic wave frequency.In the very low audio(<2000Hz),the loss tangent of dry soil dielectric is λ/ωε≈0.07,if you choose the frequency of the signal source at above 20MHz.then,ε≈ε∞,the imaginary part of the soil wave impedance is neglect,only the real part,which amounts to a pure resistance.Soil moisture sensor consists of 100MHz signal source,a coaxial transmission line and a 4-pin stainless probe.The electromagnetic waves of signal transmit to the probe along the lines.As the probe impedance and line impedance are different,the superimposition of incident waves and reflected waves forms a standing waves.Taking the coaxial transmission line as a lossless uniform line,wave impedance is Z0,Z l is the load impedance.Then the reflected coefficient of voltage wave at the probe is:Γ= (Z L-Z0)/(Z L+Z0)Choosing the length of transmission line is l=λ/4,the maximum and minimum of both ends of the line are U max and U min,Then the standingwave radio in the line can be expressed as:S=U max /U min =(1-|Γ|)/(1+|Γ|)In the way,the soil moisture radio can be measured by measuring the standing wave rate of transmission line.As shown in Fig.3.,soil moisture module consists of sensors and controllers,the sensors are subordinated to controllers,controllers can be omitted without the need of irrigation in greenhouse.To simplify the control,irrigation technology of node-type in partition is adopted in the control soil moisture in this system.To a certain extent,the parameters of upper and lower the ground can be decoupled by adopting this technology.IV CONTROL SYSTEM PROGRAMMINGThe software of PC is developed by KingView 6.51 of Beijing-controlled Asia.This configuration software has high reliability,shorter development cycle,perfect capability of graphicalinterface generation,and friendly human-computer interaction;and can create dynamic images and charts in accordance with the layout of equipment in the scene;can visually display the changes of parameters,control status,and can give an alarm when over-limited;and can achieve fuzzy control of greenhouse parameters by using the history curve of environment parameters stored in the specific database and adopting the agricultural expert system.The software of SCM of the slave is developed by Keil C51 to achieve real-time collecting,processing,uploading of the parameters and accept the fuzzy control instructions from the host computer and complete local control of the device.A.Program design of the control moduleThe software of the sub-slave machine of soil moisture module,that include the main function,subroutines of data acquisition and processing,interrupt handling and communicating etc,read the value of standing wave voltage through the parallel data port and obtained the value of soil moisture content by function calculating.The software of the slave machine of monitoring and control of soil moisture mainly complete data communication with the sub-slave machine,uploading measurement data and current control state to the host computer,accepting the fuzzy control instructions from the host computer and output the implementation instructions.The software of the slave machine of temperature and humidity,andCO2 mainly complete reading data of CO2 concentrations and temperature and humidity through the I2C concentration,uploading measurement data and current control state to the host computer,accepting the fuzzy control instructions from the host computer and output the implementation instructions.The structure of the main program and interrupt subroutine of temperature and humidity module are shown in Fig.4.The serial interrupt mode 3 is adopted by all slaves to communicate with the host,transmit the digital collecting and receive instructions.B. Program design of PC and fuzzy control system1)The communication settings of KingView 6.51:In order to ensure the correctness of communication,the upper and lower must follow the same communication protocol,set the communication ually in communication,master-slave mode is adopted in style and responder is adopted in the process.That is ,the master sent a command to the slave first,then et slave give an answer after receiving the command,thus once communication is completed.In KingView ,a scheduled polling method is adopted to do reading and writing between the lower machine by PC.In the project browser of KingView,first,click device →COM1;in the wizard of device configuration,select intelligent modules→SCM→current SCM of HEX→serial port,and then ser parameters for the host computer’s communication.2)The connection of KingView 6.51 and database:Database is the core of the software,that not only contains the definition of variables,real-time parameters and the historical parameters,but also is needed by parameters alarming,fuzzy calculating,reporting ,and displaying.Access2003 desktop database is used as records database of the system,and by using SQL,it is operated by KingView via ODBC.The procedure is :to create data variables in KingView to create a body of records to establish a data source of ODBC to create query screens and make the screen connection.To connected with Microsoft Access2003,the functions of SQLConnect(),SQLSelect(),SQLLast(),SQLNext(),SQLFist(),SQLPrew(),SQLI nsrt(),and so on,should be implemented in the command language,and then real-time storage and inquiry of data are completed.3)Software design of PC :For the control system of greenhouse,data storage capacity of the PC is unlimited,so if the existing mature software modules are include into the system,it both be relaxed and can improve the system reliability.The software of software consists of control module and management module.V CONCLUSIONAccording to the economic bearing capacity of farmer in Qinhuangdao ,with the existing technology of monitoring and control of environment parameters of greenhouse,a master-slave distributedautomatic control system of greenhouse environment in which PC is taken as the host computer is developed.The system has following characteristics:1)With the large amount of data storage of PC,fuzzy control expert system is easy of data storage,modification and system upgrading.2)By using KingView to develop software of PC,the system reliability is improved,and the development cycle is shorten,and a friendly human-computer interface is get.3)A distributed and modular structure is used in the system,it makes the system maintenance easier and adapts to production needs more. The monitoring and control modules of the slave are connected to the host through the RS485 bus based on needs,then the control of greenhouse in partition or block can be achieved.基于新的温室环境参数监测和控制系统根据实际在农村地区的温室环境参数的监测和控制,主从分布式测量和控制系统的设计需要,以其中一台计算机作为主机,该系统由PC、土壤水分测量和控制模块,温度、湿度、CO2监测和控制模块组成。
