He Lv · Railway Computer Application · 2011
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.
