第一章第一篇sectiongTwo variables u(t) and i(t) are the most basic concepts in an electric circuit, they characterize the various relationships in an electric circuitu(t)和i(t)这两个变量是电路中最基本的两个变量,它们刻划了电路的各种关系。
the charge e on an electron is negative and equal in magnitude to 1.60210×10 19C, while a proton carries a positive charge of the same magnitude as the electron. The presence of equal numbers of protons and electrons leaves an atom neutrally charged. 我们从基础物理得知一切物质是由被称为原子的基本构造部分组成的,并且每个原子是由电子,质子和中子组成的。
我们还知道电子的电量是负的并且在数值上等于 1.602100×10-12C,而质子所带的正电量在数值上与电子相等。
质子和电子数量相同使得原子呈现电中性。
We consider the flow of electric charges. A unique feature offlow of negative charges, as Fig.l-1 illustrates. This convention was introduced by Benjamin Franklin (l706~l790), the American scientist and inventor. Although we now know that current in metallic conductors is due to negatively charged electrons, we will follow the universally accepted conventionthat current is the net flow of positive charges. Thus, Electriccurrent is the time rate of charge, measured in amperes (A).Mathematically, the relationship among current i , charge q , andtime t is 当我们把一根导线连接到某一电池上时(一种电动势源),电荷被外力驱使移动;正电荷朝一个方向移动而负电荷朝相反的方向time in several ways that may be represented by different kindsof mathematical functions 我们通过方程(1-1)定义电流的方式表明电流不必是一个恒值函数,电荷可以不同的方式随时间而变化,这些不同的方式可用各种数学函数表达出来。

电气工程及其自动化专业英语翻译(精选多篇)第一篇:电气工程及其自动化专业英语翻译Electric Power Systems.The modern society depends on the electricity supply more heavily than ever before.It can not be imagined what the world should be if the electricity supply were interrupted all over the world.Electric power systems(or electric energy systems), providing electricity to the modern society, have become indispensable components of the industrial world.The first complete electric power system(comprising a generator, cable, fuse, meter, and loads)was built by Thomas Edison – the historic Pearl Street Station in New York City which began operation in September 1882.This was a DC system consisting of a steam-engine-driven DC generator supplying power to 59 customers within an area roughly 1.5 km in radius.The load, which consisted entirely of incandescent lamps, was supplied at 110 V through an underground cable system..Within a few years similar systems were in operation in most large cities throughout the world.With the development of motors by Frank Sprague in 1884, motor loads were added to such systems.This was the beginning of what would develop into one of the largest industries in the world.In spite of the initial widespread use of DC systems, they were almost completely superseded by AC systems.By 1886, the limitations of DC systems were becoming increasingly apparent.They could deliver power only a short distance from generators.To keep transmission power losses(I 2 R)and voltage drops to acceptable levels, voltage levels had to be high for long-distance power transmission.Such high voltages were not acceptable for generation and consumption of power;therefore, a convenient means for voltage transformationbecame a necessity.The development of the transformer and AC transmission by L.Gaulard and JD Gibbs of Paris, France, led to AC electric power systems.In 1889, the first AC transmission line in North America was put into operation in Oregon between Willamette Falls and Portland.It was a single-phase line transmitting power at 4,000 V over a distance of 21 km.With the development of polyphase systems by Nikola Tesla, the AC system became even more attractive.By 1888, Tesla held several patents on AC motors, generators, transformers, and transmission systems.Westinghouse bought the patents to these early inventions, and they formed the basis of the present-day AC systems.In the 1890s, there was considerable controversy over whether the electric utility industry should be standardized on DC or AC.By the turn of the century, the AC system had won out over the DC system for the following reasons:(1)Voltage levels can be easily transformed in AC systems, thusproviding the flexibility for use of different voltages for generation, transmission, and consumption.(2)AC generators are much simpler than DC generators.(3)AC motors are much simpler and cheaper than DC motors.The first three-phase line in North America went into operation in 1893——a 2,300 V, 12 km line in southern California.In the early period of AC power transmission, frequency was not standardized.This poses a problem for interconnection.Eventually 60 Hz was adopted as standard in North America, although 50 Hz was used in many other countries.The increasing need for transmitting large amounts of power over longer distance created an incentive to use progressively high voltage levels.To avoid the proliferation of anunlimited number of voltages, the industry has standardized voltage levels.In USA, the standards are 115, 138, 161, and 230 kV for the high voltage(HV)class, and 345, 500 and 765 kV for the extra-high voltage(EHV)class.In China, the voltage levels in use are 10, 35, 110 for HV class, and 220, 330(only in Northwest China)and500 kVforEHVclass.Thefirst750kVtransmission line will be built in the near future in Northwest China.With the development of the AC/DC converting equipment, high voltage DC(HVDC)transmission systems have become more attractive and economical in special situations.The HVDC transmission can be used for transmission of large blocks of power over long distance, and providing an asynchronous link between systems where AC interconnection would be impractical because of system stability consideration or because nominal frequencies of the systems are different.The basic requirement to a power system is to provide an uninterrupted energy supply to customers with acceptable voltages and frequency.Because electricity can not be massively stored under a simple and economic way, the production and consumption of electricity must be done simultaneously.A fault or misoperation in any stages of a power system may possibly result in interruption of electricity supply to the customers.Therefore, a normal continuous operation of the power system to provide a reliable power supply to the customers is of paramount importance.Power system stability may be broadly defined as the property of a power system that enables it to remain in a state of operating equilibrium under normal operating conditions and to regain an acceptable state of equilibrium after being subjected to a disturbance..Instability in a power system may be manifested in many different ways depending on the system configurationand operating mode.Traditionally, the stability problem has been one of maintaining synchronous operation.Since power systems rely on synchronous machines for generation of electrical power, a necessary condition for satisfactory system operation is that all synchronous machines remain in synchronism or, colloquially “in step”.This asp ect of stability is influenced by the dynamics of generator rotor angles and power-angle relationships, and then referred to “ rotor angle stability ”译文:电力系统现代社会比以往任何时候更多地依赖于电力供应。

第二章第一篇To say that we live in an age of electronics is an understatement. From the omnipresent integrated circuit to the equally omnipresent digital computer, we encounter electronic devices and systems on a daily basis. In every aspect of our increasingly technological society— whether it is science, engineering, medicine, music, maintenance, or even espionage—the role of electronics is large, and it is growing.谈论关于我们生活在一个电子学时代的论调是一种空泛的论调。
从无处不在的集成电路到同样无处不在的数字计算机,我们在日常活动中总会遇到电子设备和电子系统。
在我们日益发展的科技社会的方方面面——无论是在科学、工程、医药、音乐、维修方面甚至是在谍报方面——电子学的作用是巨大的,而且还将不断增强。
In general, all of the tasks with which we shall be concerned can be classified as "signal-processing“tasks. Let us explore the meaning of this term一般说来,我们将要涉及到的工作被归结为“信号——处理”工作,让我们来探究这个术语的含义吧。
A signal is any physical variable whose magnitude or variation with time contains information. This information might involve speech and music, as in radio broadcasting, a physical quantity such as the temperature of the air in a room, or numerical data, such as the record of stock market transactions. The physical variables that can carry information in an electrical system are voltage and current. When we speak of "signals", therefore, we refer implicitly to voltages or currents. However, most of the concepts we discuss can be applied directly to systems with different information-carrying variables. Thus, the behavior of a mechanical system (in which force and velocity are the variables) or a hydraulic system (in which pressure and flow rate are the variables) can often be modeled or represented by an equivalent electrical system. An understanding of the behavior of electrical systems, therefore, provides a basis for understanding a much broader range of phenomena. 信号就是其与时间有关的量值或变化包含信息的任何物理变量。

外文原文:Unattended substation and substation automation The development of automatic reclosing made the unattended substation practical .Automatic operation ,without the continuous presence of an attendant(operator),was first tried on the synchronous converter substations supplying an interurban electric railway i n 1914.In the early 1920s,the development of automatic reclosing ,protective relays ,and means for automatic control of voltage made it possible for ac substations to be completely automatic .During the period when the substations had to be controlled manually ,it was necessary that they handle enough power to justify the operator`s wages .This dictated large stations ,frequently serving large areas by means of many feeders .The feeders that served the more distant parts of an area had to go a long way before they picked up any load .Furthermore ,as the load on a large substation grows ,transformer capacity has to be added .This increases the short-circuit current on the secondary side sometimes the short-circuit capacity exceeds the interrupting capacity of the circuit breakers already installed .Appropriate remedies include bus sectionalizing ,the installation of reactors or some combination of the two .Such measures are frequently expensive and inconvenient and they constitute an undesirable limitation on operating flexibility.Once the unattended substation became a reality ,the substation could be made smaller .Located nearer the load ,and long feeders were no longer necessary .This new method of distribution had become available since load growth could now be accommodated by installinganother substation that could carry parts of the area loads formerly carried by adjacent substations .Usually ,there is no interconnection between the circuits energized by the various substations .Consequently ,there is no increase in short-circuit severity .however ,at the distribution level ,tie switches are used to switch feeders or feeder sections between transformers in the same station or to adjacent substations for substation transformer load management.Automatic control has been applied to larger and larger substations ,and to many hydroelectric generating stations .It is also used on individual circuits and equipment in many attended stations .For example ,even in many stations where an operator is on duty ,outgoing overhead feeders are controlled by automatic reclosing relays .Under some circumstances ,it may be impractical to make a station completely automatic .These circumstances could exist because of technical ,economic ,or safety considerations .A station need not be attended even though it is not fully automatic ,it is possible to control a station from another location ,such as a larger attended station or the system operating office .This can be done by means of supervisory control(a form of remote control).By means of a SCADA system ,an operator at a dispatch center can cause operations such as the opening and closing of breakers ,the starting and stopping of condensers ,and the changing of the taps on transformers with load tap changer .The operator can receive an indication that the operation has been completed .All of this can be done over a voice-grade communication channel .Itis the use of voice-grade ,two-way communication channels that distinguishes supervisory control from direct-wire remote control ;The latter requires one direct-wire circuit for each control from direct-wire remote control ;The latter requires one direct-wire circuit for each controlled device .SCADA equipment supplements automatic control .All of the protective relays and most of the control relays required for automatic control are also necessary when supervisory control is used .Only the initiating devices may be different or omitted .For example a fully automatic synchronous condenser is started and stopped by an initiating device responsive to voltage or current or both .In addition ,there are many protective and control relays .If the condenser is to be controlled by supervisory control ,all the other devices are still necessary ,and only the initiating devices can be omitted.With the recent revolution in microelectronic performance and costs ,digital automation systems are now being developed for power systems .These automation systems provide an integrated systems concept for protection ,control ,and monitoring functions .The approach utilizes distributed microprocessor-based modules located within the substations and ort on the transmission and distribution system .This provides protection and control decisions out on the system where the data is located .By automatic transmission and distribution systems ,major benefits will be obtained .There include greater utilization of existing facilities ,reduction of communication requirements ,deferral of major system investments ,optimized operations and maintenance ,improved system reliability ,more efficient-systemoperation through lower losses and rapid restoration of service after a fault the functions implemented by using this integrated systems approach include :Transmission automation functions and distribution substation and feeder automation functions.The transformer substation automation and unmanned on duty are the popular topics that the charged barbed wire net adjusts one degree automation realm nowadays, its development power head is just on the up.The abroad has a kind of standpoint to think, the person is subjected toenvironment,motion,personality,disease...etc. many factor influence easily, so oneself be a not dependable factor.Really there aren't a few troubles to being cause by the artificial mistake operation of, seeing from this angle, no man the on duty really can raise to circulate credibility.For example ZHENG4 ZHOU DI4 adjust as early as 1959 to start adopt the remote control technique, more than 30 in the last yearseses never take place a mistake operation;Again if after power supply bureau in Shenzhen carry out a transformer substation no man on duty, mistake operation the trouble rate lowered 60%.The transformer substation automation is at the calculator technique and the network correspondence technical foundation up develop.The abroad has already had the dispersion type transformer substation automation to publish in 80's, taking Siemens(SIEMENS) company as an example, that company the 1st whole dispersion type transformer substation automation LSA678 as early as 1985 circulates in the German Hanover devotion, the transformer substation that go to various electric voltage grade that 1993beginning of years have already had more than 300 systems in Germany and Europe circulate.The transformer substation automation the work start of the our country to compare with night,, about since 90's, the beginning start the stage mainly develops with produce a concentration type of transformer substation automation, example type DISA-1 the [ is one ] , type BJ-1 the [ is 2 ]s, types iES-60ses, A XWJK-1000 types, etc.s FD-97.Start develop dispersion the type transformer substation automation in mid 90's, such as the types DISA-2s, type DISA-3 [ 3, 4 ]s, BJ-F3s, type CSC-2000 the [ is 5 ]s, DCAP3200 typeseses, FDK type etc., compared with the foreign advanced level have a margin about for 10 years.Many high school,research units,the manufactory house and programming design,the seting up with circulate section at study and draw lessons from abroad forerunner technical of in the meantime, is combine the actual circumstance joint effort of the our country to continue to develop to match more our country the transformer substation automation [ of the state of the nation 3, 4, 6-12 ]s.Can anticipate, it will development and expansion from now on of speed would more and more quick, with abroad of the margin will contract gradually.One,the transformer substation categorize:Transformer substation's press the electric voltage grade can is divided into the high pressure,extra high voltage,high pressure and medium low pressure especially is 4.Especially high pressure transformer substation:1 000 KV, 750 kVs;Extra high voltage transformer substation:500 KV, 330 kVs;High pressure transformer substation:220 KV, 110 kVs, 35 kVs;Medium low-pressure transformersubstation:(call to go together with the electricity station again)10 The kV and following electric voltage grade.The transformer substation presses in the position in the charged barbed wire net can is divided into the vital point station,the terminal station with to turn 3 of stand.The vital point stand:In the charged barbed wire net regardless is the net, a structure still a burden levels all are placed in prominent position;The terminal stand:Only the high pressure enters line, locating the circuit bitter end of the charged barbed wire net;Win to turn a station:There are 2 road high pressures to enter line, locate the circuit middle.Transformer substation's press the control method can is divided in to gather to control a station(again call a base a station) and be controled a station.(call son a station again)The former is adjusted one degree center control, and as to it's the surroundings son station take to have already adjusted one degree operation mission;The latter and the terminal station are similar, but be placed in the wreath form charged barbed wire net probably in Two,BE gather to control the station control:The transformer substation presses to circulate mode demarcation to turn on duty for someone:This is the most familiar movement mode currently;Unmanned on duty:Have no fixed movement on duty a personnel, reserve only individual guard personnel, be responsible for station inside of safe security work and the trouble abnormality circumstance of urgent processing;No man value guard:No man of the real meaning station, at some flourishing west nation, if the United States,Canadian etc. is more familiar.Three,concentrate to go together with to hold mode:This kind of mode the application is the most in currently the domestic lately set up the transformer substation, and have already obtained more mature movement experience.The product of the greatly parts of factory house all belongs to this kind, among them applied have types DISA-3s,type BJ-1s,iESs,A XWJK-1000 etc.s morely.That mode and traditional mode compare, the biggest differentiation lie in RTU remote control,signal,measure,electric powercharge,correspondence etc. the function difference set hold, but from 1 or 2 control unit always through a string to go the correspondence with each function unit(hold a cabinet) and the tiny machine protection and break down to record correspondences, such as wave and the place of honor machine...etc..(see figure 3)Its characteristics is control,protect two greatest functions as a whole to consider, two back track designs greatly for simplify. Four,whole dispersion types:That mode the main characteristics take a main equipments,such as switch,transformer,female line etc., as to install unit, control,I/O,shut the unit dispersions, such as lock and protection...etc., install right on the spot on a main equipments(hold a cabinet).The station controls unit(control in the lord indoor) to go and the one for each equipments to hold a cabinet(on the spot) to connect with each other through a string, and adjust one degree center correspondence with the place of honor machine and far-away place.Concrete implement again is divided into 2 kinds of modes:Protect opposite independence, control to unite as one with diagraph, if SIEMENS etc. the product of thecompany;Protect,the control and diagraph unite as one, such as ABB, GE, the MERLIN GERIN etc. the product of the company.The SIEMENS LSA678 systemses are the typical models that the adoptions protect opposite and independent mode, having already had several hundred sets movement experience in the whole world, having already hadn't a few applied solid examples as well in the domestic in the last few years.(for example Suzhou Singapore industrial park,LIU3 ZHOU power supply bureau in Guangxi...etc.)The local factory house also releases whole dispersion type systems successively in recent years, such as the DISA-2, BJ-F3, CSC-2000, DCAP3200 etc.s(see figure 4), this mode the more suitable for request save to cover the area and two situations of electric cables, for example the city(downtown) transformer substation.The part dispersion type:This mode synthesized the characteristics of the concentrated type and dispersion type, adopting dispersion a type of system structure, but control to concentrate to go together with to hold with protection ually go together with concentration to hold to install in the dispersion of the equipmentssmallly.Equipments small at an equipments neighborhood, can establish several equipmentses according to the electric voltage grade and scale of the transformer substation small, manage nearby, economical electric cable.This mode can used for various transformer substation of electric voltage grade, being applicable to the 500 kVs and the large 220 kV station particularly.This kind of product contain DISA-3, FDK, etc.s iES-70.(see figure 5) Five,the development strategy:In the concrete implement process of the transformer substation automation, have a different implement method because of being influence by the existing profession division of labour and management system:A kind of assertion station inside supervise and control to take move(RTU) far as a data to collect with the foundation for control, correspond of the equipments also adjusts a degree by charged barbed wire net to change into foundation automatically, protecting opposite independence;Another a kind of then lay claim to a station inside supervise and control to take protect(tiny machine protection) as a data to collect with the foundation for control, the protection and control,measure to combine together, there is already this product in domestic, if etc.s CSC-2000.The latter is become a kind of development trend and consensus, so design,manufacturing,circulate and manage a section and break professional boundary, carry out integral whole to turn gradually.This is a necessity to the 110 kVs and following transformer substation.Perfectly right, current movement system,personnel from the our country equipment,profession division of labour to see, the former occupies bigger advantage doubtless.Design from the programming regardless,research manufacturing,install to adjust to try and circulate a maintenance etc. everyone's noodles, control and protect two dissimilarity profession for being all independent mutually, so the former matches the our country state of the nation more.And then because of hard provide clearer interface of trouble analysis and processing but still is circulate not easily a section to accept at that time.But install again from the developmenttrend,the technique rationality and the decreaseequipments,simplification maintenance workload etc. the aspect consider, the latter again have it the superiority.The angle flowed from the information see, theprotection(include break down to record an etc.) is with the control,measure of information sources all come from the spot TA, the TV measures exportation two times, just requesting a dissimilarity.The breakdown abnormality appearance information protected to mainly collect an equipments, request TA, the TV measures scope to compare breadth, usually according to 1000% sums settle value consideration, but measure accuracy to have lower request, the error margin is above 3%.But the control and diagraph mainly collect the movement appearance information, requesting TA, the TV measure the scope is more narrow, usually Be measuring a sum settle the value neighborhood motion, have certain request to the diagraph accuracy, measure an error margin a request at 1% in. The control that always control(CPU) unit to receive to come from the place of honor machine(the region) or far-away place directly outputs an order, can act to the protection operation back track directly after the school pit of the necessity, the province goes to controls from a distance exportation and control from a distance a performance etc. link, simplify an equipments, raise credibility.See from no man on duty angle, not only request to simplify a lord to connect the line and main equipments, but also request to simplify two back tracks and equipments, so the protection and control, measure of the integral whole turn to be advantageous tosimplifying an equipments and reduce a daily maintenance workload, to 110 kVs and the following is a 10 kVs to go together with the electricity station particularly, in addition to the voltmeter fee,power always adds etc. have diagraph accuracy to request but the beard connect the measurement TA, TV outside, other measurements make surveillance to circulate the work condition only it use, completely can with protection TA, the TV suitable for use.Can share on area net(LAN) various information of the bureau in addition, control,measure etc. all need not install each from of the data collect hardware.The control of the normal regulations hold,the information hold,imitate to hold etc. cancel may also. The transformer substation automation and no man turn on duty an implement of circulate the mode, being decided by the credibility of the equipments to a large extent.The equipments that points here not only is automate an equipments, more important electricity main equipments.Suggests the supervisor section draws up the relevant equipments manufacturing and connect oscular norm standard according to the characteristics of the transformer substation automation.Automating an equipments a manufacturer should and electricity the main equipments manufacturer strengthen a cooperation, providing a technique to unite as one of product, with convenience design,circulate a section to choose a type.Amount of logarithms the more 10 kVs go together with the electricity station, because of connecting line simple, have lower request towards protect oppositely, in order to simplify an economical investment of equipments, the suggestion is completed the circuit protection and double female line by RTU to cutover(have from hurl) etc. the protection function.Need in the RTU software to increase a protection to circulate judgment function for this, such as back up power supply from hurl function, can pass to carry out towards corresponding female line segment to lose to press to judge with the logic of the related switch appearance signal come.The transformer substation will automate from now on of the movement mode will turn on duty from no man, someone the value guard gradually toward no man a value to guard a transition.So the seeing a warnning technique(fire prevention,guard againsttheft,defend ,the waterproof vapor leak and the far-away place keep watch on etc.) and will emerge with the tide of the times, and get a quick development.Because the calculator and the network correspond by letter a technical development, RTU/LTU inside the station or protection supervision unit will get to the Internet directly, passing the network and the backstage machine(the place of honor machine) and the work station correspondence.Cancel traditional of placed the processing machine link ago, removed the correspondence"bottleneck" phenomenon thus and thoroughlySix,conclusion:a. To the extra high voltage transformer substation and the 220 kVs, the 110 kV vital point station or gather to control a station to say, proper adoption someone on duty of automation mode, still proper adjust a degree by charged barbed wire net to change into foundation automatically, protect opposite independence.But be subjected to the 110 kVs and the following to control a station,theterminal station, especially the 10 kVs go together with an electricity to stand proper doption no man on duty mode, change into foundation automatically in the programming the design the hour can the consideration with the station, then protection and control and measure the integral whole turn of project, the local function can simplify to go to cancel, generation it has a conversation window way function by person's machine of the front-panel.b. Whole dispersion type the transformer substation automations are a new topics, the manufactory house and base that need to program a design,a equipments,two equipmentses and automation equipments set up,install,circulate a section to match with closely, the orchestration arrangement.Because domestic and a manufacturing craft,material,structure of equipments and protection,control,measure unit to descend quakeproof after put,defend interference and use environment, etc. all exists a problem, should give a full value, and open an exhibition expansion work actively and steadily.c. Design the top of the manufacturing should insure to have an equipments to defend mistake operation measure,protective region and the far-away place hurl to slice(soft press plank),modify whole settle a value,return to an au to equip and the region and far-away place control to operate an equipments of ability, and promise the far-away place and control in the region, allow an an among those kinds of mode in same time valid.d.To the transformer substation automation of the whole dispersions types, it is proper to choose to use the LAN method, especially equal network, such as the total line type(lie thequality share) net, each nodes on the net the ability correspond by letter with any and other nodes directly, removing a lord thus and by the root from the bottleneck phenomenon in the way.Go together with to have another a wrong and high anti- voice of the main type CANnet net or LonWorks net and strong and carry many road of a wiretap an interview/the CSMA/CD method collide with, can add power for important information, promise the solid hour of[with] important information, raise the correspondence efficiency.e. Because the transformer substation automate the further expansion that the technical development and no man turn on duty the station movement mode, the profession of[with] protection and automation also Be permeating mutually, combine also gradually close, the original professional division of labour will break, causing a research,design thus,manufacturing,install and circulate a section of professional constitution,personnel equipment up of re- adjust a combination, with orientation protection,control,measure the integral whole turn of transformer substation automation mode.f. Suggest to greatly in particularly college the existing profession constitution do to correspond adjustment, for the convenience of in development since acquaint with to control charged barbed wire net to adjust a technical professional talented person of one degree automation again after the electricity protection.In the research design,make circulate management section and should also avoid a professional division of labour with gearing over thin,lack an orchestration consider of limit.中文译文:无人值班变电站与变电站自动化自动重合闸的研制使无人值班变电站得以实现。

Some employ the split program/data memory of the Harvard architecture, shown in Fig.3-5A-1, others follow the philosophy, widely adapted for general-purpose computers and microprocessors, of making no logical distinction between program and data memory as in the Princeton architecture, shown in Fig.3-5A-2.In general terms a single-chip microcomputer is characterized by the incorporation of all the units of a computer into a single device, as shown in Fig3-5A-3.ProgramInput& memoryOutputCPU unitDatamemoryFig.3-5A-1 A Harvard typeInput&Output CPU memoryunitFig.3-5A-2.

Principal features of a microcomputerRead only memory (ROM).ROM is usually for the permanent,non-volatile storage of an applications program .Many microcomputers and microcontrollers are intended for high-volume applications and hence the economical manufacture of the devices requires that the contents of the program memory be committed permanently during the manufacture of chips . Clearly, this implies a rigorous approach to ROM code development since changes cannot be made after manufacture .This development process may involve emulation using a sophisticated development system with a hardware emulation capability as well as the use of powerful software tools.Some manufacturers provide additional ROM options by including in their range devices with (or intended for use with) user programmablememory. The simplest of these is usually device which can operate in a microprocessor mode by using some of the input/output lines as an address and data bus for accessing external memory. This type of device can behave functionally as the single chip microcomputer from which itis derived albeit with restricted I/O and a modified external circuit. The use of these ROMlessdevices is common even in production circuits where the volume does not justify the development costs of custom on-chip ROM[2];there canstill be a significant saving in I/O and other chips compared to a conventional microprocessor based circuit. More exact replacement for ROM devices can be obtained in the form of variants with 'piggy-back' EPROM(Erasable programmable ROM )sockets or devices with EPROM instead of ROM 。

附件9:本科毕业设计外文文献及译文文献、资料题目:Increasing an individual’s quality of lifevia their intelligent home文献、资料来源:.steam.ualberta.ca文献、资料发表(出版)日期:院(部):专业:班级:姓名:学号:指导教师:翻译日期:外文文献:Increasing an individual’s quality of life via their intelligenthomeThe hypothesis of this project is: can an individual’s quality of life be increased by integrating “intelligent technology” into their home enviro nment. This hypothesis is very broad, and hence the researchers will investigate it with regard to various, potentially over-lapping, sub-sections of the population. In particular, the project will focus on sub-sections with health-care needs, because it is believed that these sub-sections will receive the greatest benefit from this enhanced approach to housing. Two research questions flow from this hypothesis: what are the health-care issues that could be improved via “intelligent housing”, and what are th e technological issues needing to be solved to allow “intelligent housing” to be constructed? While a small number of initiatives exist, outside Canada, which claim to investigate this area, none has the global vision of this area. Work tends to be in small areas with only a limited idea of how the individual pieces contribute towards a greater goal. This project has a very strong sense of what it is trying to attempt, and believes that without this global direction the other initiatives will fail to address the large important issues described within various parts of this proposal, and that with the correct global direction the sum of the parts will produce much greater rewards than the individual components. This new field has many parallels with the field of business process engineering, where many products fail due to only considering a sub-set of the issues, typically the technology subset. Successful projects and implementations only started flow when people started to realize that a holistic approach was essential. This holistic requirement also applies to the field of “smart housing”; if we genuinely want it to have benefit to the community rather than just technological interest. Having said this, much of the work outlined below is extremely important and contains a great deal of novelty within their individual topics.Health-Care and Supportive housing:To date, there has been little coordinated research on how “smart house” technologies can assist frail seniors in remaining at home, and/or reduce the costs experienced by their informal caregivers. Thus, the purpose of the proposed research is to determine the usefulness of a variety of residential technologies in helping seniors maintain their independence and in helping caregivers sustain their caring activities.The overall design of the research is to focus on two groups of seniors. The first is seniors who are being discharged from an acute care setting with the potential for reduced ability to remain independent. An example is seniors who have had hip replacement surgery. This group may benefit from technologies that would help them become adapted to their reduced mobility. The second is seniors who have a chronic health problem such as dementia and who are receiving assistance from an informal caregiver living at a distance. Informal caregivers living at a distance from the cared-for senior are at high risk of caregiver burnout. Monitoring the cared-for senior for health and safety is one of the important tasks done by such caregivers. Devices such as floor sensors (to determine whether the senior has fallen) and access controls to ensure safety from intruders or to indicate elopement by a senior with dementia could reduce caregiver time spent commuting to monitor the senior.For both samples, trials would consist of extended periods of residence within the ‘smart house’. Samples of seniors being disc harged from acute care would be recruited from acute care hospitals. Samples of seniors being cared for by informal caregivers at a distance could be recruited through dementia diagnosis clinics or through request from caregivers for respite.Limited amounts of clinical and health service research has been conducted upon seniors (with complex health problems) in controlled environments such as that represented by the “smart house”. For example, it is known that night vision of the aged is poor but there is very little information regarding the optimum level of lighting after wakening or for night activities. Falling is a major issue for older persons; and it results in injuries, disabilities and additional health carecosts. For those with dementing illnesses, safety is the key issue during performance of the activities of daily living (ADL). It is vital for us to be able to monitor where patients would fall during ADL. Patients and caregivers activities would be monitored and data will be collected in the following conditions.Projects would concentrate on sub-populations, with a view to collecting scientific data about their conditions and the impact of technology upon their life styles. For example:-Persons with stable chronic disability following a stroke and their caregivers: to research optimum models, types and location of various sensors for such patients (these patients may have neglect, hemiplegia, aphasia and judgment problems); to research pattern of movements during the ambulation, use of wheel chairs or canes on various type of floor material; to research caregivers support through e-health technology; to monitor frequencies and location of the falls; to evaluate the value of smart appliances for stroke patients and caregivers; to evaluate information and communication technology set up for Tele-homecare; to evaluate technology interface for Tele-homecare staff and clients; to evaluate the most effective way of lighting the various part of the house; to modify or develop new technology to enhance comfort and convenience of stroke patients and caregivers; to evaluate the value of surveillance systems in assisting caregivers.- Persons with Alzheimer’s disease and their caregivers: to evaluate the effect of smart house (unfamiliar environment) on their ability to conduct self-care with and without prompting; to evaluate their ability to use unfamiliar equipment in the smart house; to evaluate and monitor persons with Alzheimer’s disease movement pattern; to evaluate and monitor falls or wandering; to evaluate the type and model of sensors to monitor patients; to evaluate the effect of wall color for patients and care givers; to evaluate the value of proper lighting.Technology - Ubiquitous Computing:The ubiquitous computing infrastructure is viewed as the backbone of the “intelligence” within the house. In common with all ubiquitous computing systems, the primary components with this system will be: the array of sensors, thecommunication infrastructure and the software control (based upon software agents) infrastructure. Again, it is considered essential that this topic is investigated holistically.Sensor design: The focus of research here will be development of (micro)-sensors and sensor arrays using smart materials, e.g. piezoelectric materials, magneto strictive materials and shape memory alloys (SMAs). In particular, SMAs are a class of smart materials that are attractive candidates for sensing and actuating applications primarily because of their extraordinarily high work output/volume ratio compared to other smart materials. SMAs undergo a solid-solid phase transformation when subjected to an appropriate regime of mechanical and thermal load, resulting in a macroscopic change in dimensions and shape; this change is recoverable by reversing the thermo mechanical loading and is known as a one-way shape memory effect. Due to this material feature, SMAs can be used as both a sensor and an actuator. A very recent development is an effort to incorporate SMAs in micro-electromechanical systems (MEMS) so that these materials can be used as integral parts of micro-sensors and actuators.MEMS are an area of activity where some of the technology is mature enough for possible commercial applications to emerge. Some examples are micro-chemical analyzers, humidity and pressure sensors, MEMS for flow control, synthetic jet actuators and optical MEMS (for the next generation internet). Incorporating SMAs in MEMS is a relatively new effort in the research community; to the best of our knowledge, only one group (Prof. Greg Carman, Mechanical Engineering, University of California, Los Angeles) has successfully demonstrated the dynamic properties of SMA-based MEMS. Here, the focus will be to harness the sensing and actuation capabilities of smart materials to design and fabricate useful and economically viable micro-sensors and actuators.Communications: Construction and use of an “intelligent house” offers extensive opportunities to analyze and verify the operation of wireless and wired home-based communication services. While some of these are already widely explored, many of the issues have received little or no attention. It is proposed to investigate thefollowing issues:-Measurement of channel statistics in a residential environment: knowledge of the indoor wireless channel statistics is critical for enabling the design of efficient transmitters and receivers, as well as determining appropriate levels of signal power, data transfer rates, modulation techniques, and error control codes for the wireless links. Interference, channel distortion, and spectral limitations that arises as a result of equipment for the disabled (wheelchairs, IV stands, monitoring equipment, etc.) is of particular interest.-Design, analysis, and verification of enhanced antennas for indoor wireless communications. Indoor wireless communications present the need for compact and rugged antennas. New antenna designs, optimized for desired data rates, frequency of operation, and spatial requirements, could be considered.-Verification and analysis of operation of indoor wireless networks: wireless networking standards for home automation have recently been commercialized.Integration of one or more of these systems into the smart house would provide the opportunity to verify the operation of these systems, examine their limitations, and determine whether the standards are over-designed to meet typical requirements.-Determination of effective communications wiring plans for “smart homes.”: there exist performance/cost tradeoffs regarding wired and wireless infrastructure. Measurement and analysis of various wireless network configurations will allow for determination of appropriate network designs. -Consideration of coordinating indoor communication systems with larger-scale communication systems: indoor wireless networks are local to the vicinity of the residence. There exist broader-scale networks, such as the cellular telephone network, fixed wireless networks, and satellite-based communication networks. The viability and usefulness of compatibility between these services for the purposes of health-care monitoring, the tracking of dementia patients, etc needs to be considered.Software Agents and their Engineering: An embedded-agent can be considered theequivalent of supplying a friendly expert with a product. Embedded-agents for Intelligent Buildings pose a number of challenges both at the level of the design methodology as well as the resulting detailed implementation. Projects in this area will include:-Architectures for large-scale agent systems for human inhabited environment: successful deployment of agent technology in residential/extended care environments requires the design of new architectures for these systems. A suitable architecture should be simple and flexible to provide efficient agent operation in real time. At the same time, it should be hierarchical and rigid to allow enforcement of rules and restrictions ensuring safety of the inhabitants of the building system. These contradictory requirements have to be resolved by designing a new architecture that will be shared by all agents in the system.-Robust Decision and Control Structures for Learning Agents: to achieve life-long learning abilities, the agents need to be equipped with powerful mechanisms for learning and adaptation. Isolated use of some traditional learning systems is not possible due to high-expected lifespan of these agents. We intend to develop hybrid learning systems combining several learning and representation techniques in an emergent fashion. Such systems will apply different approaches based on their own maturity and on the amount of change necessary to adapt toa new situation or learn new behaviors. To cope with high levels ofnon-determinism (from such sources as interaction with unpredictable human users), robust behaviors will be designed and implemented capable of dealing with different types of uncertainty (e.g. probabilistic and fuzzy uncertainty) using advanced techniques for sensory and data fusion, and inference mechanisms based on techniques of computational intelligence.-Automatic modeling of real-world objects, including individual householders: The problems here are: “the locating and extracting” of information essential for representation of personality and habits of an individual; development of systems that “follow and adopt to” individual’s mood and behavior. Thesolutions, based on data mining and evolutionary techniques, will utilize: (1) clustering methods, classification tress and association discovery techniques for the classification and partition of important relationships among different attributes for various features belonging to an individual, this is an essential element in finding behavioral patterns of an individual; and (2) neuro-fuzzy and rule-based systems with learning and adaptation capabilities used to develop models of an individual’s characteristics, this is essential for estimation and prediction of potential activities and forward planning.-Investigation of framework characteristics for ubiquitous computing: Consider distributed and internet-based systems, which perhaps have the most in common with ubiquitous computing, here again, the largest impact is not from specific software engineering processes, but is from available software frameworks or ‘toolkits’, which allow the rapid construction and deployment of many of the systems in these areas. Hence, it is proposed that the construction of the ubiquitous computing infrastructure for the “smart house” shoul d also be utilized as a software engineering study. Researchers would start by visiting the few genuine ubiquitous computing systems in existence today, to try to build up an initial picture of the functionality of the framework. (This approach has obviously parallels with the approach of Gamma, Helm, Johnson and Vlissides deployed for their groundbreaking work on “design patterns”. Unfortunately, in comparison to their work, the sample size here will be extremely small, and hence, additional work will be required to produce reliable answers.) This initial framework will subsequently be used as the basis of the smart house’s software system. Undoubtedly, this initial framework will substantially evolve during the construction of the system, as the requirements of ubiquitous computing environment unfold. It is believed that such close involvement in the construction of a system is a necessary component in producing a truly useful and reliable artifact. By the end of the construction phase, it is expected to produce a stable framework, which can demonstrate that a large number of essential characteristics (or patterns) have been found for ubiquitouscomputing.-Validation and Verification (V&V) issues for ubiquitous computing: it is hoped that the house will provide a test-bed for investigating validation and verification (V&V) issues for ubiquitous computing. The house will be used as an assessment vehicle to determine which, if any, V&V techniques, tools or approaches are useful within this environment. Further, it is planned to make this trial facility available to researchers worldwide to increase the use of this vehicle. In the long-term, it is expected that the facilities offered by this infrastructure will evolve into an internationally recognized “benchmarking” site for V&V activities in ubiquitous computing.Other technological areas:The project also plans to investigate a number of additional areas, such as lighting systems, security systems, heating, ventilation and air conditioning, etc. For example, with regard to energy efficiency, the project currently anticipates undertaking two studies:-The Determination of the effectiveness of insulating shutters: Exterior insulating shutters over time are not effective because of sealing problems.Interior shutters are superior and could be used to help reduce heat losses.However, their movement and positioning needs appropriate control to prevent window breakage due to thermal shock. The initiation of an opening or closing cycle would be based on measured exterior light levels; current internal heating levels; current and expected use of the house by the current inhabitants, etc. - A comparison of energy generation alternatives: The energy use patterns can easily be monitored by instrumenting each appliance. Natural gas and electricity are natural choices for the main energy supply. The conversion of the chemical energy in the fuel to heat space and warm water can be done by conventional means or by use of a total energy system such as a Volvo Penta system.With this system, the fuel is used to power a small internal combustion engine, which in turn drives a generator for electrical energy production. Waste heat from the coolant and the exhaust are used to heat water for domestic use andspace heating. Excess electricity is fed back into the power grid or stored in batteries. At a future date, it is planned to substitute a fuel cell for the total energy system allowing for a direct comparison of the performance of two advanced systems.中文译文:智能家居能提高个人的生活品质假设这个项目是:个人的生活质量能否因为在家庭环境中运用了智能技术而得到提高呢?这种假设是很广泛的,因此,研究人员将通过调查各种各样的、有潜在研磨意识的、分节的人群来证明这个假设。
