基于PLC的电梯控制程序设计摘要随着现代城市的发展，高层建筑日益增多，电梯成为人们日常生活必不可少的代步工具。电梯性能的好坏对人们生活的影响越来越显著，因此必须努力提高电梯系统的性能，保证电梯的运行既高效节能又安全可靠。采用PLC对电梯信号系统进行控制，开发出了完整的电梯控制软件，提高了电梯的控制水平，并改善了电梯运行的舒适感，使电梯达到了较为理想的控制效果。该系统具有先进、可靠、经济的特色。该电梯控制系统具有手动和自动的功能，并且具有指层、厅召唤、选层、选向等功能。具有集选控制的特点。关键词：电梯、PLC、梯形图DESIGNONCONTROLSYSTEMOFELEVATORBASEDONPLCAbstractWiththedevelopmentofmoderncities,anincreasingnumberofhigh-risebuilding,elevatorbecomeanindispensablemeansoftransportofdailylife.Thequalityoftheliftperformanceoftheimpactonpeople'slivesbecomingmoreandmoreobvious,itmuststrivetoimprovetheperformanceofelevatorsystems,andensuretheoperationoftheliftissafe,reliableandenergyefficient.TheuseofPLCsignalsontheelevatorcontrolsystem,thedevelopmentofacompleteelevatorcontrolsoftware,toimprovetheleveloftheelevatorcontrolandimprovetheoperationoftheelevatorcomfort,sothatthelifttoreachamoresatisfactorycontroleffect.Thesystemhasadvanced,reliableandeconomiccharacteristics.Theelevatorcontrolsystemhasthedriverstoruntheoperationandnodriversormanualandautomaticfunctions,andhasmeanslayer,calledtheOfficeoftheelectionstory,electiontothefunctions.Withasetoffeaturestocontroltheelection.KEYWORDS:Elevator,PLC,LadderDiagram目录前言·················································································5第1章绪论······································································61.1电梯继电器控制系统的特点及存在问题····························61.1.1电梯继电器控制系统的优点··································61.1.2电梯继电器控制系统存在的问题····························61.2PLC及其在电梯控制中的应用特点·································61.2.1PLC的特点······················································61.2.2PLC控制电梯的优点··········································81.3课题的提出································································81.4课题的主要讨论内容····················································9电梯的功能要求·····························································9第2章电梯设备及电梯发展动态······································
