PAGE\*MERGEFORMAT1042020年4月19日基于PLC的电梯控制系统文档仅供参考于PLC的电梯控制系统设计摘要随着国民经济的飞速发展，现代化程度日益提高，高层建筑越来越多，电梯也随之增多，电梯产品在人们物资文化生活中的地位得到了提高，成为重要的运输设备之一。国内传统的电梯控制一是由继电器、接触器构成。它不但存在着可靠性差、成本高、故障率高等缺点，而且在层数增加时，配线变化给制造及安装带来诸多不便。若用PLC控制就解决了以上的不足。本文在阐述电梯的结构和可编程控制器的结构和工作原理的基础上，针对4层电梯，使用西门子S7-200可编程控制器，设计了电梯的控制系统，包括轿内指令和厅外召唤信号的登记与消除、电梯的选层和定向、电梯的开关门运行、电梯上下行控制、电梯的指层控制等部分，实现了轿内与各层呼梯指令的记录、电梯运行方向和选层的控制，电梯上下行和自动开关门、电梯的指层控制等功能。同时也使用了组态王6.53完成上位机对PLC控制电梯的仿真。关键词：四层电梯控制系统可编程控制器组态王PLC-basedelevatorcontrolsystemdesignAbstractWiththerapiddevelopmentofthenationaleconomy,theincreasingdegreeofmodernization,moreandmorehigh-risebuildings,elevatorsalsowillbeincreased,Elevatorproductsinpeople′smaterialandculturallifeofthestatushasbeenenhancedtobecomeoneoftheimportanttransportequipment.Traditionaldomesticelevatorcontrolfromthefirstrelay,acontactor.Traditionaldomesticelevatorcontrolfromthefirstrelay,acontactor.Itisnotonlypoorinthereliability,highcost,highfailurerateshortcomings,butalsoinlayersincreases,changestothewiringandinstallationofmanufacturinghasbroughtmanyunchanged,IfthecontrolbyPLCtoaddresstheaboveshortcomings.Thisarticleelaboratedtheelevatorstructure，thestructureandtheworkingprincipleoftheprogrammablelogiccontroller．Aimattheelevatoroffourfloors，thewriterdesignthiselevatorcontrolsystembytheuseofSiemensS7-200programmablelogiccontroller．Thewriterdesigntheelevatorcontrolparts,suchas,thepartofregisterandcanceltheinstructionsfromthecabin,thepartofregisterandcanceltheinstructionsfromthestationhall,thepartofchoosestationanddirection,thepartofdoormovement，thepartofelevatoroperation，thepartofshownlayer，andsoon．Thesepartsachievethefunctions：registeringtheinstructionsfromthecabinandthestationhall,choosingthedirectionandthestationofelevator，elevatorgoupordownanddoorautomatically，fingeringoutthelocationofthecabin,andotherfunctions.Alsousekingview6.53completepctoplccontrolelevatorsimulation.KeyWords：Four-storyElevator;ControlSystem;ProgrammableLogicController;kingview目录TOC\
