专业综合应用与工程能力实践训练设计说明书装瓶流水线的PLC控制系统设计院、部：电气与信息工程学院学生姓名：黄柏燊指导教师：雷军职称副高专业：自动化班级：1101班完成时间：2014年12月摘要PLC的定义有许多种。国际电工委员会（IEC）对PLC的定义是：可编程控制器是一种数字运算操作的电子系统，专为在工业环境下应用而设计。它采用可编程序的存贮器，用来在其内部存贮执行逻辑运算、顺序控制、定时、计数和算术运算等操作的指令，并通过数字式、模拟式的输入和输出，控制各种类型的机械或生产过程。可编程序控制器及其有关设备，都应按易于与工业控制系统形成一个整体，易于扩充其功能的原则设计。PLC具有通信联网的功能，它使PLC与PLC之间、PLC与上位计算机以及其他智能设备之间能够交换信息，形成一个统一的整体，实现分散集中控制。多数PLC具有RS-232接口，还有一些内置有支持各自通信协议的接口。配料工人收到每天的生产作业表后进行包装。关键词：通信；传送；配料；包装AbstractTherearemanykindsofPLCdefinition.Theinternationalelectrotechnicalcommission(IEC)isdefinedasofPLCprogrammablecontrollerisakindofdigitalcomputingoperations,speciallydesignedfortheelectronicsysteminindustrialenvironmentapplicationanddesign.ItUSESprogrammableCunZhuQi,usedinitsinternalstoragetoperformthelogicoperation,sequencecontrol,timing,countingandarithmeticoperationinstruction,andthroughdigital,analoginputandoutput,thecontrolvarioustypesofmachineryorproductionprocess.Programablecontrollerandrelatedequipment,shouldpresseasyandindustrialcontrolsystemasawhole,easytoextenditsfunctionprincipledesign.PLCwithcommunicationnetworkingfunction,itmakesPLCandPLC,betweenthePLCandthePCandotherintelligentequipmenttoexchangeinformationbetween,formingaunifiedwhole,realizescatteredcentralizedcontrol.MostPLChasRS-232interface,andsomebuilt-inhavetosupporttheircommunicationprotocolinterfaces.Ingredientsworkersreceivedailyproductionscheduling,willinturnforeachfeedstock.Accordingtohowmuchweighingingredients,firstcalculatedtheweightofeachcomponentinvariouscomponents,andthenthematerialbarrelsmaterialtaking,toelectronicsaysonthepackagingweighing.Keywordscommunication；convey；burden；pack目录1PLC简介.............................................................................................................................11.1PLC的概况.............................................................................................................11.2PLC的基本机构和特点.......................................................................................11.3PLC的工作原理....................................................................................................21.4PLC的应用领域....................................................................................................21.5PLC的结构.............................................................................................................32软件介绍............................................................................................................................52.1三菱单片机FX2N系列简介...............................................................................52.1三菱单片机FX2N在装瓶流水线中的作用....................................................53装瓶流水线的PLC控制系统设计...............................................................................63.1设计任务.................................................................................................................63.2硬件选型.................................................................................................................63.3控制内容.................................................................................................................83.4设备选型.................................................................................................................83.5软件设计.................................................................................................................93.6程序表...................................................................................................................133.7梯形图...................................................................................................................134装瓶流水线的PLC三菱GT仿真系统设计.............................................................144.1仿真环境..............................................................................................................144.2装瓶流水线的系统仿真模型建立..................................................................144.3制作工程画面.....................................................................................................154.4图形元件的定义与连接....................................................................................174.5上位监控系统组态设计....................................................................................175系统仿真调试及结果分析..........................................................................................195.1仿真结果..............................................................................................................195.2仿真分析..............................................................................................................22总结.....................................................................................................................................23致谢.....................................................................................................................................24参考文献................................................................................................................................25附录A.........................................................................................
