To provide a train detection device capable of shortening time for on-rail detection of each track circuit.SOLUTION: A train detection device is configured to apply a transmission signal TS which includes a plurality of train detection signals TD1-TD5 of different frequencies through filters F1-F5 of different pass bands to each of a plurality of track circuits TC1-TC5, and detect the on-rail state of a train on the basis of a reception signal from each of the track circuits TC1-TC5. In the train detection device, the transmission signal TS is generated by superimposing the train detection signals TD1-TD5.SELECTED DRAWING: Figure 1
【課題】各軌道回路の在線検知に要する時間を短縮することのできる列車検知装置を提供する。【解決手段】列車検知装置は、異なる周波数の複数の列車検知信号TD1〜TD5を含む送信信号TSを通過帯域の異なるフィルタF1〜F5を介して複数の軌道回路TC1〜TC5のそれぞれに印加し、各軌道回路TC1〜TC5からの受信信号に基づいて列車の在線状況を検知するように構成されている。前記列車検知装置において、送信信号TSは、複数の列車検知信号TD1〜TD5が重畳されて形成されている。【選択図】図1
