Research and design of a high performance GPS vehicle monitoring system

According to the defects of the GPS vehicle monitor system in the present market,a high concurrent and real-time GPS vehicle monitoring system is proposed. The entre system is based on a three-layer framework:the terminals,the interim database server,and the monitoring workstation. The monitor workstation is based on the MAPX platform,and the database server communicates with terminals through GPRS network. In order to reduce the communication payload,a reliable UDP protocol is used. By optimizing the database design, the high concurrence is obtained. The high efficiency of the system is proved in the implementation.
