基于PLC的升降横移式立体车库摘要：当前我国经济社会发展迅猛，人们的生活水平日新月异，汽车保有量不停增长，立体车库等特车设施的建设已远落后于汽车数量的上升，造成城市中违法违规停车的现象频发。升降横移式立体车库具有高性能、高空间利用率等特点，可以有效解决这些问题。所以本文以典型升降横移式立体车库为研究对象，通过实现车辆的自动存取，展现PLC控制技术在立体车库方面的应用。本文通过分析国内外现有立体车库的特点，以典型的双层三列五车位升降横移式立体车库为研究方案，主要介绍了升降横移式立体车库的主体结构及工作原理，确定了以PLC为主控单位的控制方案，并对控制系统的工作过程进行了介绍，选用S7-200系列PLC，完成了控制系统的输入、输出分配和PLC选型，设计了控制系统的程序流程图，完成了立体车库控制系统的程序梯形图，完成了立体车库控制系统设计。关键词：PLC；立体车库；升降横移式LiftingandtraversingtypestereogaragebasedonPLCAbstract：Withthedevelopmentofeconomicandsocialprogress,people'slivingstandardscontinuetoimprove,increasingcarownership,parkingfacilities,suchascarconstructionhasfarcouldn'tkeepupwiththenumberofcarsincreases,leadtoparking,parkingproblemisbecomingmoreandmoreserious,suchasthree-dimensionalgarageforliftingandmovingtypecharacteristicsofhighperformance,highspaceutilization,thisarticleresearchobjectfortypicalthree-dimensionalgarageliftingandmovingtype,throughtherealizationofvehicleautomaticaccess,displayofPLCcontroltechnologyintheapplicationofthree-dimensionalgarage.Inthispaper,throughanalyzingthecharacteristicsoftheexistingstereogarageathomeandabroad,putforwardatypicaldoublethreecolumnsfivestereogarageparkingliftmovetransverselytypedesign,mainlyintroducedtheliftingandmovingthemainstructureandworkingprincipleofthree-dimensionalgarage,identifiedinthecontrolschemeofPLCasthemastercontrolunit,andtheworkingprocessofthecontrolsystemareintroduced,chooseS7-200seriesPLC,completestheinput,output,distributionofthecontrolsystemandPLCtypeselection,designtheprogramflowchartofthecontrolsystem,completedthethree-dimensionalgaragecontrolsystemoftheladderdiagramprogram,completedthethree-dimensionalgaragecontrolsystemdesign.Keywords:PLC;cubicgarage;up-downandtranslaion目录1.绪论..................................................................................................................................................................11.1本课题设计的意义和目的.....................................................................................................................11.2国内和国外的研究情况.........................................................................................................................11.3PLC的用途和基本定义.........................................................................................................................21.4PLC的分类和基本结构.........................................................................................................................21.4PLC的工作原理.....................................................................................................................................32.升降横移式立体车库.....................................................................................................................................32.1升降横移式立体车库的主要组成部分.................................................................................................32.2升降横移式立体车库车位结构.....................................................
