基于GPS_GPRS车辆监控终端设计与实现

车辆定位监控系统作为高新技术中智能交通系统的一个重要分支，90年代以后得到了很大的发展。定位监控系统的发展主要受到通信网络和地理信息系统发展情况的制约。文中介绍了一种基于GPS（全球定位系统）和GPRS（通用分组无线业务）的车辆定位监控系统，给出了车载终端部分的硬件、软件的设计以及实际测试结果分析。由于采用GPRS网络进行数据传榆，使得此车辆监控系统具有实时性好、实用性好和扩展性好等优点。

Design and Realization of Vehicle Monitoring Terminal Based on GPS/GPRS

As a branch of intelligent transport system, vehicle position monitoring system has achieved large development since 1990s. The development of position monitoring system mainly depends on the progress of communication network and geographical information system. This paper describes a vehicle position monitoring system based on GPS and GPRS, gives the software and hardware design of vehicle terminals and the analysis of actual test results. Due to the use of GPRS network for transmitting positioning data, the vehicle monitoring system has such advantages as good real-time perfomance, good practicability and good scalability.
