针对中间拖车可自由编组的问题,阐述了基于MVB总线和以太网总线互为冗余的先进技术在加纳内燃动车组网络控制系统的应用研究,主要介绍了系统设计特点、网络拓扑结构、网络冗余技术以及自由编组策略。试验及实际装车表明,该技术稳定可靠,为用户极大地降低了经济成本和调试难度,同时适应用户多样化的运营需求,提高了系统的可靠性,保证列车稳定运行。 In view of the problem that middle trailers can be marshaled freely, this paper describes the application of advanced technology based on MVB bus and Ethernet bus redundancy in Ghana internal combustion EMUs network control system. It mainly introduces the system design features, network topology, network redundancy I technology and free grouping strategy. The test and the actual loading show that the technology is stable and reliable, greatly reducing the economic cost and difficulty of debugging for users, and meeting diversified operation demands of users, improving the reliability of the system and ensuring the stable operation of the train.
