摘　　要：客车远程监控系统由监控中心、数据传输网络和车载终端3部分组成,采用GPRS和internet作为数据传输中介,实现车载终端与监控中心之间的数据传输。给出系统整体设计后,重点介绍了车载终端的硬件和软件设计方案。车载终端的上位机通过GPRS模块的一个串口发送AT指令控制GPRS模块与监控中心通信,同时使用单片机通过另外一个串口监控GPRS模块的状态,一旦出现异常就将其复位,保证车载终端始终在线。现场运行证明该系统具有良好的性能。Passenger train remote monitor system consists of monitoring centre,data transmission net and termination aboard the car,adopting GPRS and internet as media,data transmission between monitoring centre and termination is implemented.After the design scheme for the whole system is presented,the hardware and software design schemes of the termination are introduced mainly.The front machine of termination controls GPRS model communicating with monitoring centre by sending AT instructions via one serial port,and MCU monitors state of GPRS model via the other serial port of the model,once abnormal state appears,MCU resets the model,then keeps termination on-line all the time.The application shows that this system has good performance.
