摘要
为了解决大规模车队同时利用短消息业务和通用分组无线业务与多个监控中心进行通信的问题 ,研究了基于上述两种通道的车辆监控通信模型 ,详细设计了其中的通信服务器的功能和结构 ,使其能够支持各监控中心自由选择监控车辆、信息广播、特殊信息优先等服务 .为了提高服务器的运行效率 ,在数据结构中充分采用了以空间换时间的方法 ,自行设计了监控接口协议 ,实现时采用了多线程、消息通信和组件技术 .
To support large-scale fleets to communicate with multiple monitoring centers using both short message service and general packet radio service, a communication server was designed based on the careful study of the communication model. The server implemented most critical communication functions such as packet switching, packet broadcasting, protocols and transferring. The thought of sacrificing memory for speed was sufficiently deployed in data structure design, and multithread, message and component technologies were used in realization to improve the efficiency of the server. The test results show that the server works effective and steady in large-scale fleets monitoring systems.
