摘　　要：设计一种基于GPS/GPRS的客车远程监控系统,能够远程监控客车实载人数、速度、位置等信息,有效地提高了客车、特别是校车的行驶安全;系统由车载终端和上位机监控两部分组成;车载终端运用STM32F103单片机采集处理GPS经纬度、车载人数、速度、紧急报警等信息,并由GPRS芯片SIM908根据TCP/UDP协议发送到指定的Internet网络服务器;上位机监控软件由VS2008和QT4联合开发而成,并加载SQL数据库,能够实现读取Internet服务器信息并显示和保存,同时根据读取的GPS经纬度信息调用google地图,直观地显示客车位置,用户还可以调用数据库查看数据历史记录;经过多次实验,系统运行稳定,定位准确,测量人数准确度达到99%。The remote monitoring system for bus based on GPS and GPRS is proposed, which can supervise the speed, location ot a bus, and the actual number of passengers on it remotely. It consists of a vehicle terminal and a monitoring software of upper computer. The vehi- cle terminal uses STM32F103 MCU for acquisition and processing of the vehicle passenger number, the emergency alarm information, the latitude and longitude data from GPS, and uses GPRS chip, SIM908, sending the informations to the specified Internet server based on TCP/ UDP protocal. PC monitoring software was developed by VS2008 and QT4 jointly. It loads the SQL database, reads informations from Inter net server, displays and saves them. At the same time, it calls Google Maps according to the latitude and longitude information from GPS, shows bus location intuitively. And users can also call database to view the data record. Validated by many experiments, the system run stably and has accurate positioning, that the measuring accuracy of the number of passengers up to 99%.
