摘　　要：近年来,我国城市轨道交通行业发展迅猛,国内一些大中型城市将轨道交通作为缓解交通拥堵和引领城市发展的首选方案。地面联调作为整个列车从设计到运营中非常重要的一个环节,能够在装车前将车辆各个系统连接并进行联调测试,有效减少接口、功能问题,提前验证相关设计功能,从而大幅节省列车在实际调试过程中耗费的时间。为了突破地面联调空间限制、降低调试成本,提出一种基于轨道交通多功能车辆总线(Multifunction Vehicle Bus,MVB)的车载网络虚拟云连接系统。该系统由本地接口装置和云管理系统2个部分组成,能够通过基于MVB总线通信的各个子系统实现远程地面联调,无须将各个不同地方的子系统集中安装在某一空间便能实现多个系统的MVB通信,从而打破MVB总线通信距离的限制,构建一个虚拟的远程连接系统。In recent years,China's urban rail transit industry has developed rapidly,and some large and medium-sized cities in China regard rail transit as the first choice to alleviate traffic congestion and lead urban development.As a very important link of the whole train from design to operation,the ground joint debugging can connect all systems of the vehicle for joint debugging test before loading,effectively reducing interface and function problems,and verifying related design functions in advance,thus greatly saving the time spent in the actual debugging process of the train.In order to break through the space limitation of ground joint debugging and reduce the debugging cost,a virtual cloud connection system of vehicle network based on Multifunction Vehicle Bus(MVB)of rail transit is proposed.The system is composed of local interface device and cloud management system,which can realize remote ground joint debugging through various subsystems based on MVB bus communication,and can realize MVB communication of multiple systems without installing subsystems in different places in a certain space,thus breaking the limitation of MVB bus communication distance and constructing a virtual remote connection system.
