停车场智能收费管理系统的设计与实现摘要：随着我国经济增长和城市化进程的加快，汽车进入家家户户，停车正在成为全球性的难题。传统停车收费的方式依靠人力计时和收费，非常的费时费力且计时计价不精确。停车场作为交通设施的一部分，需求量也日益增大，人们也对其管理领域的要求也越来越高，便捷、实用、安全已经是其基本要求。本课题以STC89C52单片机为控制核心，综合射频识别技术、红外车位检测技术等研发出一款用于停车场管理的系统。采用射频识别模块识别车辆进门时候的车牌号ID号，启动单片机记录车辆进入停车库的时间，实现自动计时开始。当车辆进入车库时，车位检测器检测到停车位自动减一，并显示剩余车位当车辆离开车库时，射频识别模块自动识别车辆信息，并自动进入计费结算界面，根据停车时间、单价自动计算停车费用后通过液晶屏实时更新剩余车位。当车辆开出后车位数释放并显示出来。本系统能够有效的解决传统人工停车收费管理的很多问题，因此，具有非常大的应用价值。关键词：智能停车场、射频识别、单片机、车位检测DesignandImplementationofParkingChargeManagementSystemAbstract：WiththeaccelerationofChina'seconomicgrowthandurbanization,carshaveenteredhouseholds,andparkingisbecomingaworldwideproblem.Thetraditionalwayofparkingchargesdependsonmanpowertimingandcharging,whichisverytimeconsumingandlaboriousandthetimingisnotaccurate.Aspartofthetransportationfacilities,theparkinglotisalsoincreasingindemand,andpeopleareincreasinglydemandingtheirmanagementdirection.Itisconvenient,fast,practicalandsafetobecomethebasicrequirementoftheparkinglot.ThisprojectdevelopsasystemforparkinglotmanagementwithSTC89C52single-chipmicrocomputerasthecontrolcore,integratedradiofrequencyidentificationtechnologyandinfraredparkingspacedetectiontechnology.TheradiofrequencyidentificationmoduleisusedtoidentifythelicenseplatenumberIDnumberwhenthevehicleentersthedoor,andthesingle-chipmicrocomputerisstartedtorecordthetimewhenthevehicleenterstheparkinggaragetorealizetheautomatictimingstart.Whenthevehicleentersthegarage,theparkingspacedetectordetectsthattheparkingspaceisautomaticallyreducedbyoneanddisplaystheremainingparkingspaces.Whenthevehicleleavesthegarage,theRFIDmoduleautomaticallyrecognizesthevehicleinformationandautomaticallyentersthebillingsettlementinterface.Theparkingfeeisautomaticallycalculatedaccordingtotheparkingtimeandtheunitprice,andtheremainingparkingspacesareupdatedinrealtimethroughtheLCDscreen.Whenthevehicleisopened,thenumberofcarsisreleasedanddisplayed.Thesystemcaneffectivelysolvemanyproblemsoftraditionalmanualparkingchargemanagement,andthereforehasgreatapplicationvalue.Keywords:Intelligentparkinglot;radiofrequencyidentification;singlechipmicrocomputer;parkingspacedetection目录第一章绪论....................................................................31.1课题研究的背景.........................................................31.2课题研究的目的.........................................................31.3课题的主要的内容.......................................................4第二章系统设计与方案论证......................................................52.1设计思路...............................................................52.2方案论证...............................................................52.2.1主控模块的方案和选择.............................................52.2.2车辆识别模块的方案和选择.........................................62.2.3车位检测模块的方案和选择.........................................62.3系统总体方案................................
