毕业设计专业：班级学号：学生姓名：指导教师：二〇一年月高速公路电子不停车收费系统HighwayElectronicTollCollectionSystem专业班级：学生姓名：指导老师：学院：年月摘要高速公路收费站ETC通道：电子不停车收费系统（ElectronicTollCollection），指的是车辆在通过收费站的时候，通过车上安装的设备实现车辆识别、信息读写（入口）并自动从之前就已经绑定好的IC卡或银行帐户上扣掉相应资金（出口），是当今交通部门以及大学研究所一直努力研究开发并推广在道路桥的一种电子收费系统。在使用电子不停车道的时候，车主只需要在车窗上安装电子标签并充值，到达收费站时可不用人工缴费，也不用停车，高速费将自动从卡片扣除。这种收费系统每个车收费过程不到两秒钟，其收费道的通行能力是人工收费通道的4-11倍。ETC指的是智能化交通系统里边的一个重要应用环节。它是由安装在汽车前挡玻璃上的一种电子标签（OBU，也是我们平常简称）并且是和收费站ETC车道上立杆安装的微波天线进行短程的通信，扣费的形式就是利用当今上位机的技术与各个银行后台的协议进行互联计算收费，达到车辆通过道路桥的收费站的时候不用停车就想是路过一个减速带一样很随意的就自动扣除了费用。但总的来说，车辆还是需要以较低速度通过收费车道。通过不停车收费这些新技术，不仅可以加快到路桥的车流量、提高通行情况、车辆运行效率同时也可以降低油耗和车辆损耗、较少污染气体的排放，及环保又节能。是当今交通部门以及大学研究所一直努力研究开发并推广的一种电子收费系统。关键词：高速公路电子不停车收费系统；ETCABSTRACTWithhighwaytollstationETCChannel:tollcollectionsystemmeansthevehiclethroughthetollstation,toachievethevehicleidentificationdevicethroughthecar,informationiswritten(entrance)andautomaticallydeductedfromtheICcardorbankaccountpre-boundfunds(exports),isaninternationallyareworkingtodevelopandpopularizetheelectronictollcollectionsystemforroads,bridgesandtunnels.Usingthissystem,theowneraslongasthewindowisinstalledandstoredproximitycardfees,theydonotpaythroughthetollstationmanually,andwithoutparking,high-speedtollisautomaticallydeductedfromthecard.Althoughabletoachievenoparking,butingeneral,thevehiclestillneedstopassaslowerspeed.Thischargingsystemtakeslessthantwosecondspervehiclefee,thefeechannelcapacityis5-10timesthelaborcostsofthechannel.TollCollectionSystem(ElectronicTollCollection,ETC)istheintelligenttransportationsystemisanimportantapplicationareasandsectors.DedicatedShortRangeCommunicationviamicrowavevehicleelectronictagandthetollstationETClanesinstalledonthevehiclewindshieldontheuseofcomputernetworkingtechnologyandbankingsystembackthesettlementprocess,soastoachievethevehicledoesnotneedtostopbytheroadandbridgetollstationwillbeabletocompletethepassagethepurposeofpaymentoffees.Bymeansoftollcollectiontechnologycanimprovethecapacitytotheroad,thevehicleoperatingefficiencywhenreducingfuelconsumptionandvehiclewearandtear,feweremissions,thatofbesaveenergyandprotectedtheenvironmentplayarole.KeyWords：HighwayElectronicTollCollectionSystem；ETCI目录1绪论......................................................................................................................31.1课题背景..........................................................................................................31.2高速公路的不同收费方式..............................................................................31.3课题研究的目的与意义..................................................................................41.4课题的主要研究内容......................................................................................42高速不停车电子收费系统ETC的研究与设计........................................................52.1设备工作条件..................................................................................................52.2设计目标..........................................................................................................62.3车道设备设计参数..........................................................................................62.4收费系统供电设计参数..................................................................................62.5系统指标..........................................................................................................72.6ETC车道系统实现方式..................................................................................72.7本章小结..........................................................................................................73电子不停车收费车道子系统和车载电路的设计....................................................83.1不停车收费系统（ETC)构成.........................................................................83.1.1车道天线、路侧读写控制器..............................................................83.1.2收费计算机系统..................................................................................83.1.3车道外围设备......................................................................................93.2不停车收费系统（ETC)功能.........................................................................93.3车载单元（OBU）..........................................................................................103.3.1MCU与射频芯片的接口通讯.............................................................103.3.2电源电路的设计................................................................................103.3.3车载唤醒电路的设计.........................................................................103.4本章小结.......................................................................................................114收费车道控制系统的设计与联系..........................................................................124.1ETC微波天线及处理器A/B.........................................................................124.2ETC自动栏杆................................................................................................144.3ETC车道信息屏............................................................................................144.4ETC雨棚信号灯......................................................................................
