RADIO DATA COMMUNICATION SYSTEM OF TRAIN AND METHOD THEREOF

摘要

A radio data communication system of a train is provided to enhance user convenience of repairing a breakdown of a train by allowing a control center to check and control every control data of the train in real time. A vehicle radio data communication device(20) is installed in a vehicle and connected with a ground device and a vehicle peripheral device(21) in order to wirelessly exchange information of a vehicle and that of the ground. When a train enters a pre-set sector, a plurality of ground radio data relay devices(30) automatically call the vehicle device(20) so as to be wirelessly connected thereto and relay data between the vehicle and a train radio data transmission central device(50). The ground devices(30) are installed at a railroad line and connected with a synthetic optical transmission path. The central device(50) is connected with every ground device(30) through a network, recognizes and controls a state of the ground devices(30), and tracks and controls a state of every train which has entered the network. A display device displays information on a train transmitted from the vehicle device(20) and various control content at a central operation console.
