摘要
阐述了一种集GPS导航技术、GPRS/CDMA移动网络通信技术、Internet技术于一体的车载导航系统,对其监控服务的系统结构、功能及其设计方法进行了分析。剖析了现有车载系统的性能特点和存在的不足,提出了基于无线通信技术的车载嵌入式终端的优势;并对车载导航系统的中心服务器(WEB Server)的设计方法及其与车载终端的双向信息传输协议进行了说明。
A vehicle-borne navigation monitor system was presented, which combined GPS navigation with GPRS/CDMA mobile network communication and Internet techniques. The structure and functions of monitor service system and its design method were described. Characteristics of the existing vehicle-borne navigation systems and their disadvantages were analyzed. The advantage of vehicle-borne embedded terminals based on wireless communication technique was pointed out. Finally, the allocation method of web server and the bidirectional information transmission protocol for vehicle terminal were described.
