基于MVB总线的市域铁路车载设备首尾通信方法OA

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.
