摘要
通过研究高速动车组车载信息车地间数据传输的应用环境和性能要求,提出适用于我国高速动车组车地间数据传输的通信协议设计方案。该协议是车载无线传输设备与地面信息采集处理系统之间用于信息交换的应用层协议,包括服务内容、通信环境的假设、通信协议中事件的定义、车地间交换信息的过程规则、车地间传输信息的报文格式等内容。介绍动车组车地间数据传输的内容分类、传输流程,动车组车地间数据传输协议的设计方案。
This paper studied the application environment and performance requirements of data transfer between EMU and stations, proposed a communication protocol which was suitable for data transmission between EMU and stations. This application layer protocol was used to exchange information between wireless transfer device on the CRH trains and the Information System of the stations. The protocol included contents of service, communication environment assumptions, definitions of events of the protocol and the format of the message. This paper introduced classification of data transmission and the process specifically, the design of this protocol.
