摘要:
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 autoadaptive 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.
