ETB在列车网络控制系统中的应用研究

Research on application of ETB in train network control system

针对列车网络控制系统中以太列车骨干网络的传输及网络协议特性,文章给出了ETB构成及编组拓扑,从底层初始化、列车拓扑发现协议初始化、协议管理和软件初始化4个方面介绍,模拟了ETB网络的具体流程,实现了ETB网络节点的自动编组。

For the transmission and network protocol characteristics of the Ethernet train backbone network in the Train control system, the paper presents the structure and topology grouping of ETB, from the four aspects of infrastructure initialization, Train Topology Discovery Protocol initialization, protocol management and software initialization. It processes the simulation of ETB network and realizes the automatic grouping of ETB nodes.
