摘要
介绍了车辆远程监控系统数据传输通道的设计实现。车载机与服务器间的信息传输是车载导航系统研究的重点,通讯通道的设计直接影响导航系统的负荷能力、实时性、稳定性。针对GPRS网络通讯的特点,研究了GPRS网络与Internet的网络套接口对接以及TCP/UDP协议数据传输方式,以较小的流量,实现了车载终端通过GPRS网络相对实时稳定的数据传输。
The design and implementation of a remote vehicle monitoring system＇s data transmission channels are proposed.The data transmission between the terminal equipment and vehicle navigation system is the focus here.The design of the tansmission channels has a direct impact on load capacity,real-time perfermance and the stability of the whole system.Considering the characteristic of GPRS network,the connection between GPRS network socket and the Internet socket,and also the characteristics of both TCP and UDP protocol data transmission are introduced.Finally,the transmission channels achieve a stable and relatively real-time data transmission between the server and terminal equipment with smaller network flow.
