自动化立体仓库毕设论文

I本科毕业设计（论文）基于PLC的自动化立体仓库设计II摘要自动化立体仓库也称自动化存取系统AS/RS(AutomaticStorage&RetrievalSystem)，是在不直接进行人工参与的情况下自动地存储和取出货物的系统。自动化立体仓库采用高层仓库货架存储货物，用专门的仓储搬运机械设备进行货物出入库作业。用可编程控制器PLC控制的自动化立体仓库实现了物流机械和计算机技术的完美结合，推动了仓储技术的全面自动化。基于PLC的自动化立体仓库系统是根据自动化立体仓库运行的基本原理而设计的。在整个控制系统中，以三菱FX2N系列的PLC作为系统中的核心控制元件，控制面板作为人机接口部件，采用3*3+1的仓库货架来存储货物，由两个步进电机来驱动巷道式堆垛机在水平和竖直方向上的运动，由一个直流电机完成货叉的取放货操作。另外，为了保证整个控制系统运行的稳定性和可靠性，在每一个仓位上设置光电传感器进行货物检测，并采用了限位开关在故障状况下进行断电急停保护。通过理论研究和逻辑推理，表明本论文所研究的自动化立体仓库技术具有一定的先进性和实用性，具备广阔的应用前景。关键词自动化立体仓库；可编程控制器（PLC）；步进电机IIIIIIAbstractAutomatedwarehouse,alsoknownasautomatedretrievalsystemAS/RS(AutomaticStorage&RetrievalSystem),isasystemwhichautomaticallystoreandretrievegoodswithoutdirecthumaninvolvement.Automatedwarehouseuseshigh-levelstorageshelvestostoregoods,andcompletesstorageoperationswithaspecialcargowarehousehandlingmachineryandequipment.AutomatedwarehousewhichisbasedonPLCachievestheperfectcombinationoflogisticsandcomputertechnology,andpromotesthefullyautomationofStorageTechnology.PLC-basedautomatedwarehousesystemisbasedonthebasicprinciplesofautomatedwarehousedesignedtorunon.Inthecontrolsystem,thePLCMitsubishiFX2Nseriesisasthecoreofthesystemcontrolelement,thecontrolpanelmemberisasahumaninterface,a3*3+1warehouseshelvesisforstoringgoods,thesteppermotoristodrivethetworoadwaystackermovementinthehorizontalandverticaldirections,aDCmotorforkstakedeliveryofthegoodstocompletetheoperation.Further,inordertoensurethestabilityandreliabilityoftheoperationofthecontrolsystem,apositiondetectingphotoelectricsensorisprovidedoneachcargo,andthelimitswitchtripisusedintheemergencypower-offprotectionatthefaultconditions.Thisthesiswarehouseautomationtechnologyhascertainlyadvancement、practicabilityandbroadapplicationprospects,throughtheoreticalandlogicalreasoning.Keywordsautomatedwarehouse；programmablelogiccontroller(PLC)；steppermotorIVV目录摘要......................................................................................................................IIAbstract..............................................................................................................III第1章绪论........................................................................................................11.1自动化立体仓库概述...........................................................................11.2国内外研究现状...................................................................................11.2.1国外研究现状................................................................................11.2.2国内研究现状................................................................................21.3课题研究意义.......................................................................................21.3.1社会意义........................................................................................21.3.2科技意义........................................................................................31.4未来发展趋势.......................................................................................3第2章自动化立体仓库设计方案....................................................................52.1仓库系统的结构设计............................................................................52.2仓库系统实现的功能............................................................................62.3仓库系统设计中的核心问题及解决方法...........................................62.4本章小结...............................................................................................7第3章系统硬件设计........................................................................................93.1主要硬件模块介绍...............................................................................93.1.1控制面板.........................................................................................93.1.2仓库货架.........................................................................................93.1.3仓储机械设备...............................................................................103.1.4光电传感器..................................................................................153.1.5电源模块......................................................................................173.2可编程控制器PLC.............................................................................183.2.1PLC的定义及特点.......................................................................183.2.2PLC的工作原理...........................................................................193.2.3PLC的选型...................................................................................203.2.4PLC输入输出I/O口分配...........................................................223.3系统电气原理图设计.........................................................................243.3.1电气原理图设计的基本步骤......................................................24VI3.3.2电气原理图的设计方法..............................................................243.3.3主电路电气原理图......................................................................253.3.4控制电路电气原理图..................................................................273.3.5元器件目录清单..........................................................................293.4系统技术参数的计算与确定......
