Network Auto-adaptive Reorganization Technology Based on Multifunction Vehicle Bus

在城市轨道交通列车通信网络技术领域,通过WTB(绞线式列车总线)来实现车辆编组变化而进行的网络重组是常用的技术方案。为了实现基于MVB(多功能车辆总线)的网络重组,从网络重组的连接方式、自适应网络系统功能、配置过程、MVB组网控制装置及MVB动态地址分配等方面,详细阐述了多功能车辆总线的网络自适应重组技术方案,并从自适应组网控制单元的功能出发,对网络自适应重组技术方案进行检测验证。检测验证结果表明,基于MVB的网络自适应重组技术方案能较为便利地实现对车辆的组网控制,能解决多单元车辆网络组网的关键问题,灵活地配置列车通信网络系统。

In the technical field of urban rail transit train communication network,network reorganization through WTB(wire train bus)to realize vehicle marshalling change is a commonly adopted technical scheme.In order to realize the network reorganization based on MVB(multifunction vehicle bus),the technical scheme of network auto-adaptive reorganization of MVB is expounded from aspects including connection mode of network reorganization,functionality of auto-adaptive network system,configuration process,MVB networking control device and MVB dynamic address allocation.The technical scheme of network auto-adaptive reorganization is tested and verified from the function of auto-adaptive networking control unit.The test results show that the MVB-based network auto-adaptive reorganization technical scheme can conveniently realize the vehicle networking control,solve the key problems in the networking of multi-unit vehicle networks and configure flexibly the train communication network system.
