PLC控制电梯毕业设计

摘要I基于PLC的电梯控制系统设计专业：铁道电气化学号：20070210010509学生姓名：郭学忠指导老师：潘红英摘要目前电梯控制系统主要有三种控制方式：继电器控制系统、PLC控制系统、微机控制系统。PLC控制系统由于运行可靠性高，使用维修方便，抗干扰性强,设计和调试周期较短等优点，倍受人们重视，已成为目前在电梯控制系统中使用最多的控制方式。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AbstractIIPLC-basedelevatorcontrolsystemdesignAbstractAtpresenttheelevatorcontrolsystemmainlyhasthreecontrolmodes:Followingelectriccircuitcontrolsystem,PLC(ProgrammableLogicController)controlsystem,microcomputercontrolsystem.PLCcontrolsystem,becausemovesthereliabilitytobehigh,theuseserviceisconvenient,anti-jamming,thedesignandthedebuggingcycleisshortandsoonmerits,timeistakenseriouslythepeopleandsoonmerits,havebecomepresentusemostcontrolmodesintheelevatorcontrolsystem.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III目录摘要.................................................................................................................................IAbstract.........................................................................................................................II第一章绪论................................................................................................................11.1电梯的国内外发展状况..................................................错误!未定义书签。1.2课题的研究背景及意义...................................................................................21.3PLC在电梯控制中的应用以及发展前景......................................................31.4课题研究的内容...............................................................................................5第二章电梯的综述....................................................................................................62.1电梯的结构及组成部件...................................................................................62.2电梯的种类.......................................................................................................72.3电梯的主要参数及性能指标...........................................................................7第三章运行方案设计..................................................................................................93.1总体方案的确定..........................................................................................103.2PLC控制系统方案设计................................................................................103.3电梯曳引方案..............................................................................................11第四章硬件选型、设计及计算..............................................................................124.1四层电梯曳引电机及门电机电路图............................................................124.2可编程控制器(PLC)的选择..........................................................................124.2.1可编程控制器(PLC)的特点................................................................124.2.2轿厢楼层位置检测方法....................................................................134.2.3PLC的选型.......................................................................................144.3变频器的选择................................................................................................154.3.1变频器的原理......................................................................................164.3.2变频器的选择....................................................................................174.3.3VS-616G5型变频器的特点.............................................................174.3.4VS-616G5型变频器的结构及参数设置.........................................174.3.5变频器自学习功能的应用方法......................................................194.3.6变频器容量及制动电阻参数的计算................................................19第五章软件设计........................................................................................................225.1电梯控制系统的主流程图..........................................................................225.2梯形图............................................................................................................235.2.1外召唤信号登记及消除.......................................................................235.2.2内指令信号登记及消除.......................................................................245.2.3电梯的平层信号处理...................................................................
