列车以太网通信技术应用

Train Ethernet Communication Technology Application

随着通信技术的迅速发展,以太网通信技术已经成熟,但列车以太网通信技术却刚刚兴起。介绍的6辆编组列车为2动4拖,拖车可以自由摘挂运行,此列车以太网通信技术采用拓扑发现协议和实时数据协议,遵循IEC 61375-2-3—2015和IEC 61375-2-5—2014标准,介绍了列车网络拓扑,终端设备与ETBN数据的交互,以太网服务质量的保证,列车固定网络的IP地址和ComId,并对采集的数据进行统计分析。

The Ethernet technology had been mature along with the rise of the communication, but the train Ethernet just started. This paper introduced a 6-car train with 2 motor cars and 4 trailers, and the trailer can be coupling and uncoupling freely. The train Ethernet used Train Topology Discovery Protocol （TTDP） and Train Real-time Data Protocol （TRDP）, which complied IEC 61375-2.-3-2015 and IEC 61375-2-5-2014. It introduced the train topology, data exchange between end device and ETBN, Ethernet Quality of Service, consist network IP address and Communication Identifier （ComId）, and statistic the data.
