摘要在计算机技术与微处理技术高速发展的推动下，PLC技术已经成为工业自动化控制领域最为常见一种控制技术。随着高层建筑的出现与快速发展，电梯的应用水平不断提升，成为现代高层建筑不可或缺的重要构成，是用户出入、货物运输的最基本工具，实现了自动化的垂直运输。利用PLC数据处理功能及其特有的输入输出接口调理功能，对电梯的开关信号的输入输出进行处理，通过楼层按钮面板，获取电梯运行的信息，实现对电梯上行下行的自动控制，并且通过软件的调试，能够实时根据电梯运行位置调节电梯运行速度，确定电梯运行状态。使得电梯能够高效、安全地运行。本课题研究具体以PLC为基础，开发设计一套五层电梯控制系统，并对控制系统的具体功能水平进行测试分析。首先分析电梯和PLC的工作原理，了解如何通过可编程控制器来应用于电梯控制系统，然后选择合适的PLC型号即西门子S7-200型号，选择合理的电梯系统的硬件，以及如何接线，确定可编程控制器的I/O分配，确定系统的软件（STEP7—Micro/WIN32）设计并调试，最后用组态王6.55进行结果演示。结果表明，基于PLC运行的自动化控制系统能够满足五层电梯的控制需求，表现出一定的应用价值和发展前景。关键词：电梯控制，组态软件，PLC,I/OABSTRACTDrivenbytherapiddevelopmentofcomputerandmicroprocessingtechnology,PLChasbecomethemostcommoncontroltechnologyinthefieldofindustrialautomationcontrol.Withtheemergenceandrapiddevelopmentofhigh-risebuildings,theapplicationlevelofelevatorsisincreasing,whichhasbecomeanindispensablecomponentofmodernhigh-risebuildings.Itisthemostbasictoolforuseraccessandtransportationofgoods,andhasrealizedtheverticaltransportationofautomation.UsingthepowerfuldataprocessingfunctionofPLCanditsuniqueinputandoutputinterfaceconditioningfunction,theinputandoutputoftheelevatorswitchsignalisprocessed.Theelevatoroperationinformationisobtainedthroughthefloorbuttonpaneltorealizetheautomaticcontroloftheelevatorupanddown,andtheelevatorcanbetransportedaccordingtotheelevatorinrealtimethroughthedebuggingofthesoftparts.Thepositionoftheelevatorisadjustedtodeterminetheoperationstateoftheelevator.Itenablestheelevatortooperateefficientlyandsafely.ThisprojectisbasedonPLC,anddevelopsafivetierelevatorcontrolsystem.Thespecificfunctionallevelofthecontrolsystemistestedandanalyzed.First,weanalyzetheworkingprincipleofelevatorandPLC,understandhowtoapplytheprogrammablecontrollertotheelevatorcontrolsystem,thenselecttheappropriatePLCmodel,theSIEMENSS7-200model,selectthereasonableelevatorsystemhardware,andhowtoconnect,determinetheI/Oallocationoftheprogrammablecontroller,anddeterminethesoftwareofthesystem(STEP7-Micro/WIN32)designanddebug,andfinallyuseKingview6.55todemonstratetheresults.TheresultsshowthattheautomaticcontrolsystembasedonPLCcanfullymeetthecontrolneedsofthefiveelevators,showingfullapplicationvalueanddevelopmentpotential.KEYWORDS:elevatorcontrol，configurationcontrol，programmablecontroller目录摘要...............................................................IABSTRACT...........................................................II目录............................................................III第一章绪论.........................................................11.1选题目的与意义..............................................11.2国内外研究现状..............................................11.3本文工作....................................................3第二章PLC电梯控制系统整体设计.....................................42.1电梯控制系统的概述..........................................42.1.1电梯工作及控制系统原理........................
