嵌入式公交车辆监控系统设计

摘要

To solve the bus safety problem ,an embedded vehicle monitoring terminal system is developed .Taking advantage on the integrated sensor technology ,video acquisition technology , GPS positioning technology ,GSM technology ,the system sends the real‐time acquisition infor‐mation to the bus monitor center via GPRS networks ,and makes the information displayed on the graphical user interface .It will send the vehicle short message when an emergency hap‐pens .It is proved by the experimental test that the system runs stably ,which ,with real‐time data ,meets the needs of the public transport safety .%针对公交车辆的安全问题，设计了公交车辆监控系统。该系统在嵌入式系统的基础上，综合传感器技术、GPRS技术、GPS定位技术、GSM 技术，实时采集公交车信息，通过GPRS网络将信息发送至公交监控中心，并在图形用户界面上进行实时显示，监控中心可将存在的危险通过短信发送至指定车辆。实验测试结果表明，该系统运行稳定，能够实时接收数据，从而满足公交安全的需要。
