CRH高速动车组中控制网络总线的应用探究

Study on Control Network Bus of CRH EMU

网络控制系统是高速动车组主要控制系统之一。在对CRH高速动车组网络控制系统中各类通信总线特点进行简要阐述的基础上,以MVB、ARCNET和CAN 3种总线为对象,对其分别构建的列车通信网络的实时响应时间进行了研究;进而分析比较了各类总线的实时响应特性,为高速列车网络控制系统中通信总线的选择、应用和优化提供了理论指导。

Network control system is one of the main control system in high-speed EMU. In this paper, we summarized features of different types of communication bus that used in CRH high-speed EMU network control system. Taking MVB, ARCNET and CAN bus as examples, we researched on the real-time response time of train communication network that based on these three bus and thus made a systematic analysis of real-time response feature of each bus of the three, thereby providing therotical foundation of choosing, optmizing communication bus of high-speed train network control system.
