摘　　要：控制网络承担着高速列车安全稳定运行的重要责任,开发出拥有自主产权的控制网络成为一种迫切需求。文章介绍了一种理想的列车控制网络——ARCNET网络,分析了ARCNET网络协议的数据传输机制,组帧方式,重点阐述了单节点的硬件构建和软件设计,并根据重庆轻轨列车的结构进行了组网设计,通过捕捉总线上的各种类型的帧解读了数据传输的全过程,同时也说明了网络功能验证成功。该系统日前已在重庆轻轨列车上开始试用。Train communication network is responsible for the safe and stable running of the high-speed train, developing a communication network of our own independent intellectual property rights becomes a kind of urgent need. This paper presents a kind of ideal train communication network—— ARCNET token bus. It gives a presentation of the mechanism of data transmission and the format of data frames, focuses on the building of single-node＇s hardware structure and implementation of software function, builds up the whole network making use of ten single-nodes according to the structure of Chongqing＇s LRV, checks out the whole processes of data communication by capturing the data on the line to prove the success of the whole network＇s function. It has begun the probation of this network on Chongqing＇s LRV.
