摘  要

 當(dāng)今世界，電梯的生產(chǎn)情況與使用數(shù)量已成為衡量一個國家現(xiàn)代化程度的標(biāo)志之一。特別是隨著城市人口的增加，人們物質(zhì)文化生活水平的提高，建筑迅速發(fā)展，大批的高樓大廈拔地而起，電梯在人們的生產(chǎn)、工作、生活中日益重要。因此對電梯的研究也顯得更加有意義。
 國內(nèi)外對電梯的研究一直沒有停止過。在理論上，電梯控制經(jīng)歷了從繼電器接觸器到PLC控制和微機控制的過程。在我國實際工程設(shè)計中，PLC由于具有可靠性高、抗干擾能力強、功能強大、可擴展性強、成本低等優(yōu)點被廣泛應(yīng)用。
 本文主要研究基于PLC的四層電梯控制，首先分析了電梯的主要結(jié)構(gòu)和控制要求，設(shè)計出電梯控制PLC的輸入輸出電路，繼而編寫梯形圖程序并通過調(diào)試，接著介紹四層電梯模型，經(jīng)過系統(tǒng)通信達到控制四層電梯模型運行的效果，本研究對于電梯行業(yè)的進一步研究有著積極的意義。

Abstract

 Nowadays,the manufacture capability and using quantity of elevator is one of the symbols of national modernization degree.Especially,along with urban population increase and people’s corporeal life quality have been raised greatly,architecture field develop rapidly that a large of high building and large mansions appear as if bamboo shoots in spring come out of ground after raining.The elevator has been playing a key role in our life such as production working and daily life.Therefore,study on elevator is much more significant.
 People never stop study on elevator.On theory,elevator controls system had gone through three phases that from relay-connector control to PLC control and then Computer control.Inactual engineering design in our country,PLC is popular applied in virtue of its advantage such as high-reliability,excellent anti-jamming ability,strong function,wonderful expansibility and low cost etc.
 This paper mainly does a research on elevator control based on PLC, Firstly,the main construction and control requirement of elevator is analyzed;the PLC program is designed.Secondly, the elevator model system is designed by MCGS configuration software. Finally, admiting plc as lower computer meanwhile the configuration system is simulated by PLC。As a result ，we can control the real elevator model in ourlifies。This technique is significant to the more research on elevator control and industry spot monitor.
