PLC自动升降机控制设计摘要自动升降机作为楼群建筑中垂直运行的交通工具已与人们的日常生活密不可分。实际上自动升降机是根据外部呼叫信号以及自身控制规律等运行的,而呼叫是随机的,自动升降机实际上是一个人机交互式的控制系统,单纯用顺序控制或逻辑控制是不能满足控制要求的,本论文采用可编程控制器(PLC)取代微机实现信号集选控制。PLC可靠性高,程序设计方便灵活,抗干扰能力强、运行稳定、可靠性高等特点,所以现在的自动升降机控制系统广泛采用可编程控制器(PLC)来实现。在自动升降机控制系统中,采用PLC构成的系统,具有可靠性高,故障率低,维修方便等优点。本系统设计就是采用三菱PLC(FX-1s)作为自动升降机模型的控制装置。实验证明,该系统能较直观地描述自动升降机的结构,将自动升降机的机械传动与电气控制有机地结合起来,较全面地演示自动升降机的使用功能;通过修改PLC控制程序,可在该模型上,实现多种自动升降机运行、控制方式,不仅可以作为实验设备,也可为自动升降机的科研提供了一个模拟平台。关键词PLC自动升降机三菱PLCAbstractTheelectricelevatoristhemeansoftransportationdailylifeinterwovennessthattheperpendicularityrunsinbuildinggroupbuildingalreadywithpeople.Thattheelectricelevatoristhatthecallsignwaitstoworkaccordingtotheoutsideaswellasoneselfcontrolslawinfact,butcallforisrandom,theelectricelevatoristhatonepeoplemachineiseachotherdyadicinfactcontrolsystem,theselectionscontrollingthebetobeabletonotbesatisfiedwithcontrollingcallfor's,thisthesisexclusivelywithsequentialcontrolorthelogicadoptprogrammingcontroller(PLC)tosubstitutePCrealizingsignalcollectioncontrols.PLCreliabilityheight,programminggoestothelavatorynimbly,theanti-interferenceabilitystrong,runsstability,theadvancedcharacteristicofreliability,adopttocometocometrueprogrammingcontroller(PLC)thereforeliftcontrolnowsystemisbroad.Inelectricelevatornavar,adoptthesystemthatPLCcomposes,havereliabilityheight,malfunctionrateslow,bemaintainedwaitingformeritconveniently.SystemdesignsthecontroldevicebeingtoadoptMitsubishiPLC(FX-1s)tobetheelectricelevatormodel.Demonstration,thatsystemcandescribetheelectricelevatorstructuremorepenetrating,combineelectricelevatormechanicaldriveelectriccontrolorganicallydemonstratetheelectricelevatorsigmatismfunctionmoreall-round;ByrevisingPLCunderthecontrolofprocedure,mayonthatmodel,realizevariouselectricelevatoroperation,underthecontrolofway,notonlybeingabletobeexperimentequipment,alsomaysimulateplatformfortheelectricelevatorscientificresearchhasprovidedoneKEYWORDPLCElectricelevatorMitsubishiPLC目录第一章绪言.................................................................................................................................................1第二章四层自动升降机模型.......................................................................................................................2第一节自动升降机...............................................................................................................................2第二节四层自动升降机模型...............................................................................................................2第三节系统控制...................................................................................................................................2第四节技术参数...................................................................................................................................3第三章可编程序控制器(PLC)................................................................................................................4第一节PLC...........................................................................................................................................4第二节PLC程序设计步骤...................................................................................................................4第四章四层自动升降机模型PLC控制系统的设计..................................................................................5第一节设计目的...................................................................................................................................5第二节设计要求...................................................................................................................................5第三节I/O分配.....................................................................................................................................6第四节硬件接线图...............................................................................................................................7第五节梯形图程序设计.......................................................................................................................7第六节plc接线图.................................................................................................................................7结束语.............................................................................................................................................................8谢辞.................................................................................................................................................................9参考文献.......................................................................................................................................................10附录一梯形图.............................................................................................................................................11附录二plc接线图.......................................................................................................................................14电子科技大学毕业论文(设计)编程控制器(PLC)电梯控制设计1第一章绪言随着城市建设的不断发展,楼群建筑不断增多,自动升降机在当今社会的生活中有着广泛的应用。自动升降机作为楼群建筑中垂直运行的交通工具已与人们的日常生活密不可分。实际上自动升降机是根据
