基于MVB总线的北京地铁八通线国产化网络系统适用性研究

Research on Applicability of the Localized Network System of Beijing Subway Batong Line Based on MVB Bus

针对北京地铁八通线列车总线数据传输信息少的问题,对现有车辆网络系统进行了国产化改造。对网络系统拓扑结构、硬件设备、软件功能等方面进行了优化改进,将基于多功能车辆总线(MVB)技术的国产化列车网络系统(TCMS)应用到现有车辆改造项目中,并归纳分析了国产化过程中遇到的技术难点及实际问题。国产化网络系统各方面性能参数满足现有车辆要求。

Regarding the problem of insufficient data transmission in train bus of Beijing Subway Batong Line,localization reform has been carried out on the existing subway network system.The topology structure,hardware equipment and software functions of the network system have been optimized and improved.The localized train network system(TCMS)based on multi-function vehicle bus(MVB)technology is applied to the existing vehicle renovation project,and the technical difficulties and practical problems encountered in the process of localization are summarized and analyzed.All performance parameters of the localized network system meet the requirements of existing vehicles.
