摘要
鉴于目前国内地铁列车网络架构的多样性,不利于行业标准体系的建立以及用户的使用维护,文章分析了标准地铁列车控制与管理系统统型方案的选型,并从冗余性、可靠性等方面对环网方案和链路聚合网方案进行了全面的分析和对比;针对以太网环网架构中数据传输安全方面的要求,介绍了列车以太网通信的安全协议以及如何保证数据传输在全路径中安全有效的手段。
In view of the diversity of current domestic metro train network architecture,it is not conducive to establishment of the industry standard system and the use and maintenance of users.This paper describes the selection of TCMS unified program for standard metro train,and comprehensively analyzes and compares the ring network program and the link aggregation network program in terms of redundancy and reliability.According to the safety requirements of data transmission in the Ethernet ring network architecture,the safety protocol of the train Ethernet communication and how to ensure the safe and effective means of data transmission in the full path are presented.
