以太网在地铁列车上的发展与应用

国内地铁列车网络主要采用的MVB总线型架构,该架构由于其传输速率低等局限性,已无法满足列车网络的发展需求.以太网以其通信速率高、灵活性强等特点在各领域得到迅猛发展.文章通过阐述以太网在国内地铁列车上的应用,并结合实际工程案例介绍以太网与MVB双网冗余方案、以太网为主的以太网和MVB双冗余方案、纯以太网控车方案,指出各方...

Development and application of ethernet in metro trains

MVB bus structure is mainly adopted in domestic metro train network in China.Due to its limitations such as transmission rate,it cannot meet needs of train network development.Ethernet has developed rapidly due to the characteristics of high communication rate and high flexibility.This paper explores the application of ethernet in metro trains in China and introduces the dual network redundancy scheme of ethernet and the MVB combined with practical engineering cases"ethernet based"ethernet and MVB dual redundancy scheme and pure ethernet train control scheme,and points out the shortcomings of each scheme,so as to provide reference for TCMS design or technical management of metro trains in the future.
