1高速公路的通信技术的特点摘要：高速公路是衡一个国家公路交通现代化水平的重要标志之一我国高速公路起步较晚.但发展速度较快.到2016年底我国高速公路通车里程己达到5.3万公里。位居世界前列。所谓移动通信，是指移动体与固定体或另一移动体之间的信息交换，因此他必须采用无线方式。在高速公路的运营管理中，无论是养护管理,路政管理还是交通管理，都离不开移动通信技术，所以建立高速公的专用移动通信系统十分必要。本文就移动通信技术应用的具体方面作出详细的分析，对于现在移动通信技术在高速公路中的不足作出一定思考，希望能够改进现阶段还不太成熟的情况。使它在高速公路日常管理的指挥调度、路政执法、收费稽查、排障抢险等方面都发挥了更大作用，取得了更显著的社会和经济效益。关键词：高速公路：通信；技术2Abstract:highwayisoneoftheimportantsymbolofthelevelofmodernizationofanationalhighwaytrafficbalanceofExpresswayinChinastartedlate.Butthedevelopmentspeedisquick.Bytheendof2016,China'shighwaymileagehasreached53thousandkilometers.Rankingintheworld.Mobilecommunicationreferstotheexchangeofinformationbetweenamobilebodyandafixedbodyoranothermovingbody.Intheoperationandmanagementofhighway,whetheritismaintenancemanagement,roadmanagementortrafficmanagement,cannotbeseparatedfromthemobilecommunicationtechnology,itisnecessarytoestablishahigh-speeddedicatedmobilecommunicationsystem.Makeadetailedanalysisofthespecificaspectsoftheapplicationofmobilecommunicationtechnology,tomakecertainthinkingnowforthelackofmobilecommunicationtechnologyinexpressway,hopetobeabletoimprovethepresentsituationisnotmature.Makeitplayagreaterroleinthedailymanagementofthehighwaycommandandcontrol,highwaylawenforcement,inspectionfees,emergencyrescueandotheraspects,andachievedmoresignificantsocialandeconomicbenefits.Keywords:highway;communication;Technology目录摘要...............................................................................................................................IAbstract........................................................................................................................II引言.............................................................................................................................11关键技术应用.......................................................................................................11.1手机定位技术.............................................................................................11.2无线视频监控技术............................................................................................11.3车载GPS技术.............................................................................................21.4短信通知技术.............................................................................................23方案设计...............................................................................................................33.1系统选型.....................................................................................................33.1.1系统功能.......................................................................................43.1.2呼叫功能........................................................................................43.1.3介入系统特性................................................................................43.1.4系统可靠性特性............................................................................43.2系统设计............................................
