摘　　要：介绍了基于GPS、GPRS技术的远程管理终端设备设计方案。采用uC/OS实时操作系统协调各个任务的并行处理;描述了利用LPC系列单片机接收GPS输出定位信息的解析方法;运用CAN总线获取车辆运行和故障信息,并给出了具有抗干扰功能的CAN总线设计电路图;阐述了利用中国移动GPRS公用无线网络,与internet上的服务器进行通讯的实现方法。实践证明,在某型挖掘机上该方案能有效的利用internet远程获取挖掘机的车辆定位信息、运行参数和故障信息,并且采用了多种抗干扰设计,具有更高的可靠性。The software and hardware design of vehicles＇ long-range management and diagnose system was presented based on GPS/GPRS technology. The parallel dealing of various tasks was coordinated using uC/OS real-time operating system. An analytical method was given which used LPC-series MCU（Main Control Unit） to receive the GPS information. The CAN bus was used to acquire the vehicle s＇ running and fault information, and the circuit diagram of CAN bus design with anti-jamming function was given. The realization method that terminal communicated with Intemet server using GPS public lineless network of China Mobile was expounded. The application in some types of digging vehicle show that the positioning information, circulate parameter and fault information could be effectively acquired by using Intemet long-distance network, and this scheme is more reliable due to its manifold anti-jamming designs.
