TRAIN CONTROL DEVICE

To provide a train control device capable of performing seamless switching between an active system transmitter and a standby system transmitter while increasing a train control area.SOLUTION: In a train control device, a ground device 1 transmits an ATC signal to a plurality of track circuits 1T, 2T, 3T, etc. and an on-vehicle device 3 receives the ATC signal to control the traveling of a train 2. The ground device includes an active system and standby system transmitters 7a, 7b generating a plurality of ATC signals having frequencies different in each track circuit in a time shared manner. When at least one ATC signal generated by the active system transmitter 7a is abnormal, the active system transmitter is switched to the standby system transmitter 7b during a period of outputting normal ATC signals among the plurality of ATC signals to the other track circuit.SELECTED DRAWING: Figure 1 【課題】列車制御領域を拡大しつつ、常用系送信器から予備系送信器へシームレスな切り替えができる列車制御装置を提供する。【解決手段】列車制御装置は、地上装置１から複数の軌道回路１Ｔ，２Ｔ，３Ｔ，...にＡＴＣ信号を送信し、車上装置３で受信して列車２の走行制御を行う。地上装置は、軌道回路毎に周波数が異なる複数のＡＴＣ信号を時分割に発生する常用系と予備系の送信器７ａ，７ｂを備え、常用系の送信器７ａが発生するＡＴＣ信号の少なくとも１つが異常な場合に、複数のＡＴＣ信号のうちの正常なＡＴＣ信号を他の軌道回路へ出力している期間中に予備系の送信器７ｂに切り替える、ことを特徴とする。【選択図】図１
