【正文】 及時(shí)的監(jiān)視。這不但實(shí)現(xiàn)了電梯的科學(xué)集中管理，而且降低電梯維修費(fèi)用。 電梯控制系統(tǒng) 電梯的控制主要是指對(duì)電梯在運(yùn)行過(guò) 程中的運(yùn)行方向、轎內(nèi)指令、層站召喚、負(fù)載信號(hào)、樓層顯示、安全保護(hù)等指令信息進(jìn)行管理，操縱電梯實(shí)行每個(gè)控制環(huán)節(jié)的方式和手段。 電梯的用途不同，可以有不同的載荷，不同的速度及不同的驅(qū)動(dòng)方式和控制方式。即使相同用途的電梯，也可采用不同的操縱控制方式。但電梯不論使用何種控制方式，所要達(dá)到的目標(biāo)是相同的，即根據(jù)轎廂內(nèi)指令信號(hào)、層站召喚信號(hào)而自動(dòng)進(jìn)行邏輯判定，決定出哪一臺(tái)電梯接受信號(hào)，自動(dòng)定出電梯的運(yùn)行方向，并按照指令要求通過(guò)電氣自動(dòng)控制系統(tǒng)完成預(yù)定的控制目的。 電梯控制系統(tǒng)分類 從控制系統(tǒng)的實(shí)現(xiàn)方法來(lái)看，電梯的控制系 統(tǒng)經(jīng)歷了繼電器電梯控制、可編程序控制器（ PC機(jī)）、單片微機(jī)控制、多微機(jī)控制多種形式，這些控制方式代表了不同時(shí)期電梯控制系統(tǒng)的主流，并且隨著大規(guī)模集成電路和計(jì)算機(jī)技術(shù)的發(fā)展而逐步推陳出新，這些控制系統(tǒng)在目前的在用電梯中都有存在。 PLC 控制系統(tǒng) :PLC 是可編程序控制器的簡(jiǎn)稱，它是一種數(shù)字運(yùn)算操作的電子系統(tǒng)。它采用可編程序的存儲(chǔ)器存儲(chǔ)執(zhí)行邏輯運(yùn)算、順序控制、定時(shí)、計(jì)數(shù)和算術(shù)運(yùn)算等操作指令，并可通過(guò)數(shù)字式或模擬式輸入和輸出。 用 PLC 控制電梯的方法是，將電梯中發(fā)出的指令信號(hào)諸如基站的電源鑰匙、轎內(nèi)選層指令、層站召 喚、各類安全開(kāi)關(guān)、位置信號(hào)等都作為 PLC 的輸入，而將其它的執(zhí)行元件如接觸器、繼電器、轎內(nèi)和層站指示燈、通訊設(shè)施等作為 PLC的輸出部分。 根據(jù)電梯的操縱控制方式，確定程序的編制原則。程序設(shè)計(jì)可以按照繼電器邏輯控制電路的特點(diǎn)來(lái)完成，也可以完全脫離繼電器控制電路重新按電梯的控制功能進(jìn)行分段設(shè)計(jì)。前者程序設(shè)計(jì)簡(jiǎn)單，有現(xiàn)成的控制線路作依據(jù)，易掌握；后者可以使相同功能的程序集中在一起，程序占用量少。 PLC 用于電梯的控制系統(tǒng)具有可靠性高，穩(wěn)定性好；編程簡(jiǎn)單，使用方便；維護(hù)檢修方便等優(yōu)點(diǎn)。 現(xiàn)在 PLC產(chǎn)品，品種齊全，已成 系列化，輸入輸出點(diǎn)數(shù)從 30點(diǎn)一直到 8千多點(diǎn)乃至更多。完全可以滿足不同層高的電梯控制要求。 外文原文 PLC application in the development trend of the elevator Programmable Logic Controller (PLC) is a mon control device which use puter technology as a core, PLC gets a wide range of applications in all walks of life. In the elevator industry, PLC’s role has been fully expressed. This paper introduces the PLCcontrolled model of a fivestory elevator， include it’s position, main function, the I/O interface distribution of the PLC, the PLC’s programming methods and procedures design of the elevator system. With procedures design of the elevator control system can achieve the elevator door’s opening and closing control, and the elevater’s indication under the call, moving from top to bottom, startingup, delay closed, Ping layer, opening the door, making signals in the queue, close to the escalator and alarming control under the mode of the elevator’s operation mode. Through the process of piling software, hardware connection and the conjunction of elevator model and the PLC control system, which makes the elevator control system model intuitive reflected in the course of operation and realized the elevater’s functional control. The 21st century will develop multipurpose, fullfeatured tower building, ultrahigh speed elevator continue to bee the research direction. Traction type superfast elevator research continues to super capacity motor, high performance by the microprocessor, damping technology, new roller guide boots and security clamp, permanent mag synchronous motor, elevator car air pressure relief and noise suppression systems propulsion. Using the linear motor drive there is also a greater research space elevator. Future superfast elevator intimacy will have increased significantly. Elevator iWith economic development, the increasing number of highrise buildings, elevators have bee indispensable in daily life the vertical transport. Better meet user requirements, development of high security, high reliability, high efficiency, low energy consumption, ride fort of the elevator, the elevator is the domestic and foreign enterprises and research institutions the main control system which was developed to achieve these objectives, the most important ways. The rapid development of industrial automation technology for the elevator control system technology update provides the material base. Continue to be the most advanced areas of industrial control technology and products introduced to the elevator control, elevator industry, technology development is the most important and effective article programmable puter controller PCC, the puter technology, munication technology, automatic control technology for the integration of new areas of industrial control industrial control device, used in the lift China s elevator industry, technology status and development trend of the detailed analysis, based on this paper, B amp。 R 2020 PCC as the elevator s main control system, pleted a 12storey station set selective control passenger elevators in the hardware and software control program design , the use of PCC its own has the logic operation and data processing functions, through appropriate increase in input / output point and the preparation of PCC control procedures, so that the system has run for the elevator fault monitoring and diagnosis functions, and further information on the PCC control system Elevator Remote in close connection with the machinery of largescale electrical machinery and electronic products. Mainly by the room, Wells Road, Car, door systems and electrical control system. Acpanied by the development of the construction industry, to provide for the construction of the elevator up and down traffic and transport industries are developing rapidly. Elevator is not only an important link in the production of equipment, but also a life of work and the necessary equipment, can be expected that, with the development of society, elevator products in people39。s material and cultural life and the car will be has
