摘　　要：列车控制网络是面向控制的一种连接车载设备的网络通信系统,是分布式列车控制系统的重要组成部分,它能够通过信息的实时交互来实现对列车各种车载设备的通信、管理与控制等。通信协议是网络运行的最基本的保障,协议实现情况的好坏对于网络以及列车的正常运行都有重要的意义。本文对CRH2型车通信网络协议实现情况的分析方法进行了研究,并且设计了协议实现情况的分析工具,分析内容包括协议报文封装的分析,协议工作流程的分析,不同应用报文封装的分析,不同应用工作流程的分析等。Train control network was a control-oriented network communication system which connected different kinds of device in the train. It was also an important part of distributed train control system. It could implement communication, management and control to train device by real-time communication. The protocol was the basic ensure for the network work. The implementation situation of protocol was of significant meaning to the network and the train operation. This paper studied on the analysis method of the implementation for the protocol of CRH2 EMU communication network, designed a tool which helped to achieve this object. The analysis was contained analysis to the packet encapsulation of the protocol, analysis to the work flow of the protocol, the analysis to the application packet encapsulation and the analysis to the work flow of different application.
