GPRS在动车组车载故障信息无线传输过程的应用

摘要

This paper introduced the process of on-board real-time data and fault datagram transmission from train to ground by GPRS in Fault Diagnosis System of EMU. MC55 embedded module was used for GPRS module. GPRS module sent AT instruction through the serial port to transfer datagram between train and ground. It was convenient for the administrators to learn the status and manage the real-time fault of EMU.%本文介绍了动车组故障诊断系统中,车载实时数据和故障报文通过GPRS传输到地面服务器的具体实现过程.GPRS模块采用了西门子MC55模块.GPRS模块通过向串口中发送AT指令,实现向地面服务器传输车载实时报文,为地面管理人员及时了解动车组运行状况并进行故障处理提供方便.
