PROBLEM TO BE SOLVED: To provide a train radio system in which it is not necessary to arrange base stations to enable hand-over in the range of a train length, thereby reducing the number of base stations in a route.SOLUTION: A train radio system includes: on-vehicle devices 61a and 61b having train control parts 63a and 63b for performing creation of position information and control of a train speed, and storing on-vehicle databases 650a and 650b, and radio communication parts 62a and 62b for transmitting the position information from the train control parts 63a and 63b from antennas 69a and 69b; radio base stations that communicate with the on-vehicle devices 61a and 61b; and a ground control device for controlling an operation of the train based on the position information received through the radio base stations. The on-vehicle databases 650a and 650b include a train length and the positions of the antennas 69a and 69b. The radio communication parts 62a and 62b switch the radio base stations when the positions of the antennas 69a and 69b are beyond a hand-over point on the on-vehicle databases 650a and 650b.

    【課題】列車長の範囲でハンドオーバー可能なように基地局を配置する必要がなく、路線内の基地局数を削減することができる列車無線システムを得ること。【解決手段】位置情報の生成と列車速度の制御を行い、車上データベース650a,650bを記憶する列車制御部63a,63b及び列車制御部63a,63bからの位置情報をアンテナ69a,69bから送信する無線通信部62a,62bを有する車上装置61a,61bと、車上装置61a,61bと通信する無線基地局と、無線基地局を介して受信した位置情報に基づいて列車の運行を制御する地上制御装置と、を備え、車上データベース650a,650bには列車長とアンテナ69a,69bの位置が含まれ、無線通信部62a,62bは、車上データベース650a,650b上においてアンテナ69a,69bの位置がハンドオーバー点を越えたときに無線基地局を切り替える。【選択図】図2
