摘要介绍基于AT89S52单片机的一款停车场自动停车收费管理系统,该自动停车收费系统采用比传统停车计费方式更优越的红外线检测计费方式,采用红外线检测计费方式,所需存储容量小,具备了自动开启关闭大门功能、自动计费功能、显示功能(显示停车场状况)、查询功能,而且收费方式可以调节,使系统更具灵活性。该自动停车收费系统操作简单,价格低廉,安装调试方便,很好地解决了临时停车场的管理收费问题。整个自动停车收费管理系统操作简单、价格低廉、安装调试方便,能够满足管理临时停车场的要求。本系统的实际开发使用将大大节省临时停车场的管理费用及人手,提高临时停车场的利用效率。此外,该自动停车收费管理系统还可以方便地实现信息加密和各种功能扩展,通过改进可成为通用型停车场收费管理系统。关键词:单片机;停车场;自动停车收费系统ABSTRACTThemanagementsystemintroducingthatonemoneyparkinglotautomationmotorstoppageofmonolithicmachinechargesowingtoAT89S52,isthesystemparkingvoluntarilycharging'sturntoadopttheplanparkingratiotraditiontowastemoreadvantageouswayinfraredraydetectingplanfeeway,adoptinfraredraytocheckplanfeeway,requiredmemorycapacityhasbeensmall,havehadthefunction(situationdemonstratingparkinglot),inquiryfunctionopeningautomaticallyclosingtheentrancedoorfunction,theautomationmeterfeefunction,showing,andchargewayisnotbadadjust,makeflexibilityhavemoresystematically.Thatautomationmotorstoppagechargessystematicallyhandlingasimplicity,priceischeap,theinstallationdebugginggoestothelavatory,problemhavingresolvedchargeforprovisionalparkinglotadministrationverygood.Chargeforentireautomationmotorstoppagemanagesthesystemoperationsimplicity,priceischeap,assemblesadebuggingtogotothelavatory.Beabletosatisfythecallformanagingprovisionalparkinglot's.Originallysystematicrealitydevelopsadministrationcostandhandbeingputintousewilleconomizeprovisionalparkinglotgreatly,improvesprovisionalparkinglotutilizationratio.Besides,bethemanagementsystemparkingvoluntarilycharging'sturntobeabletorealizeencryptedandvariousinformationfunctionexpansionconveniently,chargeforparkinglotmanagessystembyimprovingbutbecomingthetypebeingappliedoruseduniversally.KeyWords:Monolithicmachine;Parkinglot;Chargeforautomationmotorstoppageissystematic目录1引言.................................................................................................................................12课程任务.........................................................................................................................32.1系统框架...................................................................................................................32.2工作流程...................................................................................................................43主要的功能元器件介绍.................................................................................................53.1元器件介绍...............................................................................................................53.1.174LS138..........................................................................................................53.1.2LM358.............................................................................................................63.2LED显示部分..........................................................................................................73.2.1LED显示器.............................................................................................
