To provide a track circuit device which makes train detection signals have multifarious information, using relatively simple constitutions.SOLUTION: A track circuit device 1 comprises a transmitter 2 and a receiver 3. The transmitter generates a train detection signal from a commercial AC 4 and can transmit, to a track circuit TC, the train detection signal whose phase deviates from the commercial AC by an amount corresponding to prescribed information. The receiver receives the train detection signal from the track circuit TC, detects if a train T is on the track circuit TC based on the received signal, extracts the prescribed information corresponding to the phase deviation between the received signal and the commercial AC and carries out processing which is based on the detected result about an existence of a train on the track circuit TC and the extracted prescribed information.SELECTED DRAWING: Figure 1

    【課題】比較的簡単な構成により列車検知信号の多情報化を図る軌道回路装置を提供する。【解決手段】軌道回路装置1は、商用交流4から列車検知信号を生成すると共に、商用交流に対して所定情報に対応した位相をずらして列車検知信号を軌道回路TCに送信可能な送信機2と、軌道回路TCから列車検知信号を受信し、受信信号に基づいて軌道回路TC上に列車Tの有無を検知すると共に、受信信号と商用交流との位相のずれに対応した所定情報を抽出し、軌道回路TC上の列車の有無の検知結果及び抽出した所定情報に基づく処理を実行する受信機3と、を含む。【選択図】図1
