基于服务器推送技术的WebGIS车辆实时监控系统的设计与实现的中期报告 Abstract Thereal-timemonitoringofvehicleshasbecomeanimportantpartoflogisticsmanagement.WebGIStechnologycanintegratespatialinformationwithbusinessdataandpresentitvisually,whichisverysuitableforvehiclemonitoring.However,toachievereal-timemonitoring,thetraditionalWebGISsystemneedstoconstantlycommunicatewiththeserver,whichconsumesalotofnetworkresourcesandaffectsthesystemperformance.Therefore,thisprojectcombinesthepushtechnologyoftheserverandtheWebGIStechnologytoachievereal-timemonitoringofthevehicle. Introduction Thepurposeofthisprojectistodesignandimplementareal-timemonitoringsystemforvehiclesbasedonWebGIStechnology.Thesystemcandisplaythereal-timepositionofthevehicleandthespeedanddirectionofthevehicleonthemapinreal-time,andprovidealarmremindersforvehicleabnormalsituations.Thesystemcanprovideeffectivehelpforlogisticsmanagementanddispatching. ResearchObjectives -DesignandimplementaWebGIS-basedvehiclemonitoringsystemwithreal-timemonitoringcapabilities. -Researchandimplementserverpushtechnologytoachievereal-timemonitoring. -Provideauser-friendlyinterfaceformonitoring,querying,andmanagingvehicleinformation. ResearchProgress Intheinitialstageoftheproject,weconductedasurveyofexistingvehiclemonitoringsystemsandanalyzedtheiradvantagesanddisadvantages.WealsostudiedWebGIStechnologyandrelateddevelopmenttools.Inthemiddlestage,wecompletedthedesignandimplementationofthesystemarchitecture,anddesignedtheuserinterfaceofthesystem.Atthesametime,wealsostudiedtheserverpushtechnologyandresearchedanddevelopedthecorrespondingserver-sideandclient-sidecode.
