摘要针对中小型皮带运输机的控制系统采用继电器控制，致使生产效率低，生产成本高，企业的竞争能力差，本文利用三菱FX2N系列PLC控制皮带输煤机，有手动控制和自动控制两种控制方式，实现了软件与硬件相结合的控制方法，是皮带运输机自动化控制系统改善和提高的一条有效途径，用四条皮带运输机的传送系统，分别用四台电动机带动，具有较高的应用推广价值。该系统用可编程序控制器（PLC）作为控制核心，结合电动装置、称重传感技术的自动运输。在软件设计中，给出了程序流程图，并设计出梯形图程序，出现故障时可及时发出警报信息。此外，研究了MCGS在皮带运输机控制系统中的应用。利用组态软件MCGS设计了皮带运输机控制系统监控界面，进而为维修和故障诊断提供了多方面的可能性，充分提高了系统的工作效率。关键词：三菱PLC，皮带输送机，自动化AbstractAccordingtothecontrolsystemofsmallandmediumsizedbeltconveyorwithrelaycontrol,resultinginlowproductionefficiency,highproductioncost,theenterprisecompetitionability,thispapermakesuseoftheMITSUBISHIFX2NseriesPLCcontrolofbeltconveyer,amanualcontrolandautomaticcontroltwocontrolmode,controlmethodrealizesthecombinationofsoftwareandhardware,isabeltconveyoraneffectivewaytoimprovetheautomationcontrolsystem,transmissionsystemwithfourbeltconveyer,respectivelywithfourmotordrive,hasahigherapplicationvalue.Thesystemusesprogrammablelogiccontroller(PLC)asthecontrolcore,andcombinespneumatictechnology,sensingtechnologyandpositioncontroltechnologytocontroltheautomatictransportationofproductson-site.Inthesoftwaredesign,theprogramflowchartisgiven,andtheladderdiagramprogramisdesigned.Whenthefailureoccurs,thealarminformationcanbesentoutintime.Inaddition,theapplicationofMCGSinthecontrolsystemofbeltconveyerisstudied.ThemonitoringinterfaceofbeltconveyorcontrolsystemisdesignedbyusingconfigurationsoftwareMCGS,whichprovidesmanypossibilitiesformaintenanceandfaultdiagnosis,andimprovestheworkingefficiencyofthesystem.Keywords:MITSUBISHIPLC,beltconveyor,automation目录1总体方案设计.....................................................................................................................11.1皮带运输机的结构..................................................................................................11.2运输机的工作流程..................................................................................................21.2.1启动...............................................................................................................21.2.2停止...............................................................................................................31.3系统的设计内容......................................................................................................32皮带运输机装置控制系统的硬件设计.............................................................................42.1可编程控制器（PLC）的选型...............................................................................42.2传感器的选择..........................................................................................................52.3电机选择..................................................................................................................52.4通信接口..................................................................................................................52.5触摸屏......................................................................................................................62.6中间继电器....................
