Abstract

This application relates to the field of rail transit and to a train wireless communication system, comprising: a train-level network management unit and a vehicle-level network management unit; the vehicle-level network management unit is connected to and communicates with other vehicle-level network management units and / or train-level network management units in the same train formation; the train-level network management unit obtains its own location information through wireless communication; establishes communication with the train-level network management units of the train formation to be networked, sends its own vehicle information and location information to the train-level network management units of the train formation to be networked, and receives the vehicle information and location information of the train-level network management units of the train formation to be networked; generates a train-level network communication node sorting table based on its own and the vehicle information and location information of the train-level network management units to be networked; and implements train-level addressing function according to the train-level network communication node sorting table, thus solving the problem of multi-train communication reconnection using wireless communication technology.
