摘要
介绍了一种采用GPRS技术的车载定位系统软件设计。阐述了车载定位系统的组成结构和工作原理,并介绍了在ARM嵌入式系统中实现TCP/IP以及PPP等网络协议栈的方法。利用GPRS(General PacketRad io Service)永久在线、通信速率高等优势,系统实现了监控中心与车载终端之间信息的实时交互。而且系统的有效性、稳定性已经在实际应用中得到验证。
This paper discussed a software design of the onboard navigation system, using GPRS tech- nology. The architecture and working theory of this system is introduced in details, focusing on the design of software stacks such as TCP/IP, PPP and etc, on the ARM embedded hardware system. Using GPRS （ General Packet Radio Service） permanent on - line, the correspondence speed higher superiority, the system realized the monitoring center and the vehicle carries between the terminal the information real - time alternately. The validity and stability of the system have been justified in practical applications.
