Abstract：Based on the intellgent development need of urbanrail vehicles，the train intelligent information network system has been studied and designed. This system is built up in the Ethernet architecture centered around the multi-network integration technology and the ring network redundancy technology.By configuring the vehicle-born inteligent data centerunit，the data are uniformly collected，stocked anduploaded/ downloaded，which satisfies the needs of massive information fusion and bearing as well as wireless transmission and solves the problem of the inability to comprehensively bear and remotely upload the vehicleborn operation information of train in the past. The design process fully embodies the characteristics of inteligence，security and informatization，achieving the distributed collection and the data fusion of raw data from various monitoring subsystems. The data are uploaded to the ground operation and maintenance platform through the wireless network channels，realizing functions such as status monitoring，fault warning and health assessment of subsystems and key components and providing the remote diagnosis and the expert technical support for the train operation.
