基于以太网的列车多网融合技术研究

Research on Multi-Network Convergence Technology of Trains Based on Ethernet

文中研究了基于以太网的列车多网融合技术,通过Vlan划分、优先级调度等方法将维护网、PIS网、走行部内网、列车控制网等多网融合到一条千兆网,并通过MAC帧的分析、传输竞争优先级处理、时效性保障、传输机制、安全保障等措施来保证各承载业务的正常通信,对于多网融合技术的研究和开发具有一定的参考价值。

This paper studies the train multi network integration technology based on Ethernet.By using VLAN division,priority scheduling and other methods,the maintenance network,PIS network,internal network of running gear,train control network and other multi networks are integrated into a gigabit network.Through the MAC frame analysis,transmission competition priority processing,timeliness guarantee,transmission mechanism,security and other measures to ensure the normal communication of each service,it has a certain reference value for the research and development of multi network integration technology.
