To provide a method by which a train in a specific section is made to stop without using the information of the train location in a train radio system.SOLUTION: A train radio system 1001 comprises a mobile train station 104, plural base stations 103 arranged along a travel track of a train 105 and assigned peculiar base station numbers and a central device 102 communicating with the mobile train stations 104 through a corresponding base station. Each base station 103 notifies own base station number to the mobile train station 104 in a radio communication area 103A. The mobile train station 104 stores the base station number notified by the base station 103 and transmits a protection warning signal including the stored base station number to the central device 102 through the corresponding base station. The central device 102 selects a base station number based on the base station number included in the protection warning signal and transmits a protection receiving signal including the selected base station number to the plural base stations 103.SELECTED DRAWING: Figure 1
【課題】本発明は、列車無線システムにおいて、列車位置情報を使用することなく特定区間の列車を停止することを目的とする。【解決手段】列車無線システム1001は、列車移動局104と、列車105の走行線路に沿って配列され、固有の基地局番号が割り当てられた複数の基地局103と、対応基地局を介して列車移動局104と通信する中央装置102と、を備え、各基地局103は、自身の基地局番号を無線通信エリア103A内の列車移動局104に通知し、列車移動局104は、基地局103から通知された基地局番号を記憶し、記憶した基地局番号を防護発報信号に含めて対応基地局を介して中央装置102に送信し、中央装置102は、防護発報信号が含む基地局番号を基に基地局番号を選択し、選択した基地局番号を防護受信信号に含めて複数の基地局103に送信する。【選択図】図1
