【正文】 f intelligence building has been put different meanings along with the development of early stage intelligence building had been thought that it is equal to the intelligence mansion,but now the intelligence building not only includes the intelligence mansions but also involves intelligence residential districts. This paper mainly disusses one subsystem of intelligence building system:the elebvator control system. In intelligence residential districts the enterprise’s information managing system mainly takes charge of the things which related to the daily life,for example supervising the district equipments,managing vehicles,disposing critical sutuations and so on..The elevator supervising and control system is also necessary to the intelligence residential to make people feel safe,stable and fortable and how to save energy resources and protelct environments and so on are the basic requirements to the elevator control system.Control system PLC is a mon industry control is a special industry control puter which has the perfect function and simple PLC strong ability in interference and so on makes the elevator industry one after another to apply the PLC to the elevator control system,in order to replace the relay being used in traditional elevator control Application of PLC in the elevator control system reduces the breakdown rate and efficiently improves the operating reliability of the elevator with paper mainly discusses the elevator control system’s working principles,the system’s sofeware and hardware realization methods and so on.. The Working Principles of Elevator Control System are stated as follows:The spot control imformation is send into the PLC from the customer input devices firstly,then the PLC control cabinet is required to send out the control signal to drive the equipments according to the system demands. The elevator can the perform the homologous action according to the control are velocity feedback devices in system,which adopt measure velocity generators to provide the elevator velocities and generally are installed in the tail of tow this is a feedback control system,which can improve the system’s control precision. It is not necessary to do interface circuit in the elevator’s PLC control we should do is to send the signals to PLC digital input signals include inside and outside calling signals,floor location inspecting signals,limiting location signals,opening and shutdown the elevator door signals PLCoutput points can be directly used to control transducers for the purpose of electrical motor’s positive turn and reverse,stop and control each segment velocity and so on. Moreover,input and output devices are needed in elevator control system,vesides the PLC,system’s major control device. The control cabinet is the control center,from which we can send out variout control control cabinet often was installed in the elevator electic devices and signal systems,for emample the contactors,relays,tectifiers and transformers etc,are centralized in the control Power of the control cabinert was imported from the chief power of the elevator power was also introduced into control panel fy soft cables and was linked with each control power lines which was derived from control cabinet was delivered to tow electric control lines and signal lines were separately sent to each floor junction. The design includes two part: hardware and hardware design is the base of that the control demands are relativelu plex,we design the programs separately according to the control follow the principle as follows。When the elevator is ascending,the ascending demands are prior to other demands When the elevator isdescending,the descending demands are prior to other demands. he Sequential Function Chart is adopted during the boxes to form elevator’s executive circuitry design. t is a method specially used in industrial sequential SFC method can describe the system’s working procedure in great detail When all SFC are drawn and I/O address lists are presenten,we can convert the SFC to Ladder design trict demands for time and for locked each other,we introduce working bits to remember working should write out the working bits control program,which can link together each step and make the pervious step as the next step restriction the actual outputs are the logic bination of these working steps. The system program has been dubugged pletely at experiment enunciates that the design method is of PLC in the elevator control system is an effective can make the personnel of the industry management center to longdistance monitor and control the elevator in control center,to connect the elevaor system with intelligence building industry management system by Ethemet or specialpurpose network such as Lon elevator,but also can lower the elevator maintenance costs is one of the developing direction of intelligence building elevator control system.譯文PLC在智能建筑電梯控制系統(tǒng)中的應(yīng)用在20世紀(jì)80年代，第一座智能大廈在美國竣工，之后智能建筑引起了全世界的關(guān)注。隨著社會(huì)的發(fā)展，智能建筑有著不同的含義。早期智能建筑被認(rèn)為是等同于智能大廈，但是現(xiàn)在智能建筑不僅涉及智能大廈，而且還涉及智能住宅小區(qū)。本文主要討論了智能建筑系統(tǒng)的一個(gè)子系統(tǒng)：電梯控制系統(tǒng)。智能住宅區(qū)內(nèi)企業(yè)的信息管理系統(tǒng)主要是負(fù)責(zé)涉及到日常生活的事物，例如監(jiān)管住宅區(qū)內(nèi)的設(shè)備，車輛，處理緊急情況等等，電梯的監(jiān)管可控制系統(tǒng)對(duì)智能住宅小區(qū)來說也是必須的。如何使人們感到安全，穩(wěn)定和舒適，以及如何節(jié)約能源資源和保護(hù)環(huán)境等是電梯控制系統(tǒng)的基本要求。Plc可編程控制器是一種常見的工業(yè)控制設(shè)備，是一種特殊的工業(yè)控制計(jì)算機(jī)，具有完善的功能和簡單的框架，plc具有強(qiáng)抗干擾能力等優(yōu)點(diǎn)，使得電梯工業(yè)一次又一次將plc應(yīng)用于電梯控制系統(tǒng)，以取代傳統(tǒng)的使用繼電器控制電梯系統(tǒng)。Plc在電梯控制應(yīng)用，減低了故障率，并有效的提高了電梯運(yùn)行的可靠性與安全性。本文主要論述了電梯控制系統(tǒng)的工作原理，系統(tǒng)軟件和硬件實(shí)現(xiàn)方法等。電梯控制系統(tǒng)工作原理說明如下：首先將使用者現(xiàn)場(chǎng)的輸入信息發(fā)送到plc中，然后plc控制裝置通過系統(tǒng)要求發(fā)出信號(hào)以驅(qū)動(dòng)外圍設(shè)備，然后電梯根據(jù)控制要求執(zhí)行相應(yīng)的動(dòng)作，系統(tǒng)中的速度反饋裝置，采用的是測(cè)速裝置測(cè)出電梯運(yùn)行速度反饋給控制裝置，通常安裝在曳引電動(dòng)機(jī)后面，所以該系統(tǒng)是一個(gè)反饋控制系統(tǒng)，可提高系統(tǒng)的控制精度。電梯的plc控制系統(tǒng)的接口電路不需要設(shè)計(jì)，我們要做是將信號(hào)，包括電梯內(nèi)外召喚信號(hào)，平層監(jiān)測(cè)信號(hào)，開門和關(guān)門信號(hào)等發(fā)送給plc的數(shù)字輸入端口。排列成中的直流電源，提供給指示燈，plc輸出點(diǎn)直接控制傳感器，已達(dá)到電動(dòng)機(jī)正轉(zhuǎn)和反轉(zhuǎn)，停機(jī)的目的。此為，電梯控制系統(tǒng)中除了plc和主要控制裝置外還包括其他輸入和輸出的裝置?？刂乒袷钦麄€(gè)控制系統(tǒng)的核心部分，可以發(fā)送各種控制命令，通常安裝在電梯內(nèi)。電氣設(shè)備和信號(hào)裝置。例如，接觸器，繼電器，電容，電阻，整流器和變壓器等，也都安裝在控制柜內(nèi)，控制柜中的電源是有電梯室內(nèi)的主電源提供。電梯室內(nèi)的主電源還通過由軟電纜做成的導(dǎo)線連接到各個(gè)控制按鈕，電動(dòng)機(jī)也是由它供電，控制線和線號(hào)線分別接至各個(gè)樓層。設(shè)計(jì)包括兩個(gè)部分：硬件和軟件。硬件設(shè)計(jì)是軟件設(shè)計(jì)的基礎(chǔ)?？紤]到控制的要求相對(duì)復(fù)雜，我們按照控制功能將程序分塊。此外電梯還必須遵循以下調(diào)度原則：當(dāng)電梯上行時(shí)，任何反方向即下降的呼叫按鈕呼電梯均無效；當(dāng)電
