摘要
基于列车以太网的ETB(Ethernet Train Backbone)初运行是新一代列车网络控制技术的关键。概述了列车以太网架构和列车拓扑发现协议TTDP(Train Topology Discovery Protocol),并深入分析了列车初运行的建立过程及相关算法。搭建列车以太网网络试验平台,进行ETB初运行试验,得到ETB初运行结果。最后通过对Wireshark软件抓取的TTDP拓扑帧分析,验证了初运行结果。
The ETB inauguration based on train Ethernet is the basic part of the new generation of train control network technology.This paper summarizes the train Ethernet architecture and the train topology discovery protocol TTDP,and analyzes the establishment process and related algorithms of train ETB inauguration.Build train Ethernet network test platform for ETB inauguration test, get the ETB inauguration results.Finally,through TTDP topology frame grab Wireshark software analysis to verify the inauguration results.
