Research on Health Assessment Method of Train Communication Network

Train communication network is a data communication network that transmits information to all kinds of intelligent on-board equipment on the train. It is the basis for the whole train to realize information sharing, control function, monitoring and diagnosis. If the train communication network fails, it will pose a serious threat to the safe operation of the train. Therefore, it is of great significance to carry out the research on the online monitoring system of the health status of the train communication network, so as to grasp the health status information of the train communication network online, which will improve the safety and reliability of the train operation and realize the condition maintenance. In this paper, based on the research of online monitoring system for the health status of train communication network and the research status of PHM technology and health assessment of train communication network, an online assessment method for the health status of MVB network is proposed.
