基于PLC的三层电梯控制系统设计VIP专享VIP免费

I摘要现今社会中，经纪发展迅速，高楼大厦，日益增多，高层建筑中，楼层高的有几十层，仅仅是楼梯已无法达到人们的需求，电梯的出现解决了这一难题，所以，电梯的发展也成为了一种趋势，对于电梯控制越来越高，被人们所青睐，成为了高层建筑中的列班车。人们生活好了，对于安全以及生活舒适度的要求也更高，因而电梯在之后的发展中，也随着这一趋势发展。对于如何达到乘客乘坐电梯时，既安全又舒适这一问题，电梯的控制要求在电机调速、控制精度、以及调速范围等等，在各个方面提出了更加严格的控制要求。随着工业需求发展，PLC也由此诞生，利用PLC控制，为其提供了更为宽广的发展方向。PLC因工业而生，随着其发展，其体积越来越小、功能也越来越完善控制效果更加稳定、能够减小外界干扰对其的影响。具有把机械和电气元器件，集成在一个系统里的功能。因此，PLC对于电梯的发展，也成为了其操作的关键技术。关键词：电梯、PLC、继电器IIIIIABSTRACTInthemodernsociety,therapiddevelopmentofthebrokerage,high-risebuildings,increasingly,high-risebuildings,floorshigh,dozensoflayerisonlystairshavebeenunabletomeetthedemandofpeople,theemergenceoftheelevatorsolvedthisdifficultproblem,therefore,thedevelopmentoftheelevatorhasalsobecomeakindoftrend,forelevatorcontrolmoreandmorehigh,favoredbypeople,becameahigh-risebuildingcolumnsinthebus.Peoplelivingwell,alsototherequirementofsafetyandcomfortoflifeishigher,sotheelevatorinlaterdevelopment,alsowiththedevelopmentofthistrend.Abouthowtoattainthepassengerelevator,safeandcomfortablethisproblem,theelevatorcontrolrequirementsinthemotorspeedandcontrolprecisionandspeedrangeandsoon,putsforwardthemorestrictcontrolrequirementsineachaspect.Alsowasborn,withthedevelopmentofindustrialdemand,PLCcontrolusingPLC,providedthedevelopmentdirectionofwider.PLCforindustry,alongwithitsdevelopment,itsvolumeismoreandmoresmall,functionalsomoreandmoreperfect,thecontroleffectismorestable,canreducetheinfluenceofinterferenceonthe.Withthemechanicalandelectricalcomponents,thefunctionofintegratedinasystem.Therefore,PLCforthedevelopmentoftheelevator,hasbecomethekeytechnologyofitsoperationKeywords:elevator，PLC，relayIV目录前言......................................................................1第一章电梯的概述..........................................................31.1电梯的定义..........................................................31.2电梯的框架..........................................................31.3电器部件............................................................41.4电梯控制系统发展的现状..............................................51.5电梯继电器控制系统的特点及存在问题..................................61.6电梯技术发展趋势....................................................6第二章PLC的概述..........................................................82.1定义................................................................82.2功能................................................................82.3特点................................................................92.4PLC与其他工业控制系统的比较........................................122.5发展历史............................................................142.6PLC的现状及发展趋势................................................14第三章三层电梯的设计......................................................163.1控制系统设计的基本原理..............................................163.2控制系统总体设计方案................................................163.2.1控制要求............................
