基于MVB总线的市域铁路车载设备首尾通信方法

Head-to-tail Communication Method of Urban Railway On-board Equipment Based on MVB Bus

市域铁路是适用于都市圈中心城市城区连接周边城镇组团的轨道交通系统,提供公交化、大运量、快速便捷的交通服务。市域铁路要求列车两端的车载设备首尾通信、传递信息、支持站后自动折返和原地自动换端。详细介绍基于MVB总线的首尾通信方法和技术,已经成功应用于市域铁路车载设备之中。经过实验室测试和检验,提出的首尾通信方法和技术可以实现首尾两端车载设备高安全、高可靠的数据通信,是市域铁路列车实现站后自动折返和原地自动换端的重要基础技术。

The urban railway is a rail transit system that is suitable for connecting the central urban area of the metropolitan area with the surrounding urban clusters,providing public-focused,large volume,fast and convenient transportation services.The urban railway requires that the on-board equipment at both ends of the train be able to perform head-to-tail communication,support automatic turn-back behind the station and automatically change ends in the station.This paper introduces in detail the head-to-tail communication method and technology based on MVB bus,which has been successfully applied to the urban railway on-board equipment.After laboratory testing and inspection,the head-to-tail communication method and technology proposed in this paper can achieve high safety and high reliability in data communication between the on-board equipment at the head and tail of the train,which is an important basic technology for urban railway trains to realize automatic turn-back behind the station and automatic end change in the station.
