摘要
提供了笔者在实际工程应用中总结出的一些经验 ,为人们设计实用的、具有广泛推广价值的GPS(全球卫星定位系统 )车辆监控系统提供参考 ;从数字地图、无线通信以及GPS三个部分入手 ,通过总结实际工程应用中遇到的问题和客户反馈的意见 ,探讨了目前车辆监控系统中存在的一些问题以及针对这些问题提出的解决方案 ;多次跑车实验结果和客户长期试用的信息反馈显示 ,笔者提出的方案解决了车辆监控系统中存在问题对系统的影响 ,该方案已应用于实际工程 。
The purpose of this paper was providing some experience and ready reference for people who could design a utile and abroad popular GPS vehicle monitoring system. The author demonstrated some problems existing in the vehicle monitoring system, such as digital map model errors lead to map matching errors; telecommunication system information lag results in vehicle real time position error and global position system multipath error affects vehicle position. The authors had provided some schemes for solving the problems,e.g. GIS/DR protocol for solving telecommunication system information lag,nerve cell for solving global position system multipath. Experiment showed that the solution schemes had eliminated the system errors.The solution schemes had been applied to some projects,and had acquired very good application effect. [
