基于PLC的仓库堆垛机控制系统设计摘要摘要：随着社会飞速发展，电子商务交易下，货物的流通量日益增长，使得人工对货物的控制也显得效率不高，劳动强度大；本文以SiemensS7-200系列PLC为控制器，结合上位机组态软件Wincc，设计、模拟了自动仓库货物控制系统上位机与PLC的系统的数据交换采用OPCScout协议技术；系统大概工作过程为货物经检录入仓后，经机器人取货放入主传送带，主传送带一侧的传感器对货物进行分析检测，传感器信号传达至PLC，PLC输出相应命令驱动气动执行机构，进行货物的控制，货物被拣入缓存仓后经机器人取货至出仓，或者分发到立体仓库经堆垛机进行货物的储存；系统体现了现代自动化技术，运行稳定的同时更易于操作员的监控。关键词：PLC控制系统自动化IIABSTRACTABSTRACT：Withtherapiddevelopmentofsociety,underthee-commercetransaction,thecirculationofgoodsisincreasing,makingthecontrolofthegoodstooinefficientandlaborintensive;thisarticleusestheSiemensS7-200seriesPLCasthecontroller,combinedwiththeupperunitWinccsoftware,designedandsimulatedtheautomaticwarehousecargocontrolsystem,thedataexchangebetweenthehostcomputerandthePLCsystemadoptstheOPCScoutprotocoltechnology;thesystemprobablyworksasfollows:afterthegoodsarecheckedintothewarehouse,therobotpicksupthegoodsandputsthemintothemainconveyorbelt.Thesensoronthesideofthemainconveyorbeltanalyzesanddetectsthegoods,thesensorsignalistransmittedtothePLC,andthePLCoutputsthecorrespondingcommandtodrivethepneumaticactuatortocontrolthegoods.Afterthegoodsarepickedupintothebufferwarehouse,therobotpicksupthegoodstothewarehouse,ordistributesthem.Thewarehouseisstoredinathree-dimensionalwarehousethroughastacker;thesystemembodiesmodernautomationtechnology,whichisstableandeasytomonitorbyoperators.Keywords:PLCcontrolsystemautomationIII目录摘要................................................................IABSTRACT...........................................................II目录..............................................................III1绪论..............................................................11.1研究背景及内容..............................................11.2仓库货物控制系统概述........................................11.3堆垛机的概述................................................22仓库堆垛机控制系统总体方案设计....................................42.1控制系统总体设计............................................42.2控制系统设计的基本原则......................................52.3控制系统设计的主要内容......................................52.4堆垛机系统的控制要求........................................73仓库堆垛机控制系统的硬件设计......................................93.1PLC选型.....................................................93.2电机选型...................................................113.3传感器选型.................................................114仓库堆垛机控制系统的软件设计.....................................134.1系统涉及软件...............................................134.2系统主流程图...............................................204.3控制系统子程序.............................................215仓库堆垛机控制系统的组态设计.....................................235.1组态软件...................................................235.2组态设计...................................................246结论.............................................................32致谢.............................................................33参考文献..............................
