To provide a track relay for saving the labor of adjustment work by automatically detecting a phase difference between a level of a track input and a local input during installation and for readjusting a train detection threshold by automatically following the train detection threshold to variation of the track input during operation.SOLUTION: A track relay 1 of this invention determines whether a train is in an on-rail state or is not in the on-rail state by comparing a slot average value 5' in a prescribed time interval of a track voltage 5 with a threshold (V) of a set track voltage 5, controls output information on the basis of the determination result, and compares the variation of the track voltage 5 with a result of arithmetic processing for automatically following the threshold (V) to make a determination.SELECTED DRAWING: Figure 2
【課題】設置時において、軌道入力のレベルと局部入力との位相差を自動検出して調整作業を省力化し、運用時には軌道入力の変動に対して列車検知しきい値を自動追従させて再調整する軌道リレーを提供する。【解決手段】本発明の軌道リレー1は、軌道電圧5の所定の時間間隔におけるスロット平均値5´と、設定された軌道電圧5のしきい値(V0)との比較により列車が在線状態か非在線状態かを判定し、この判定結果に基づいて出力情報を制御し、軌道電圧5の変動に対しては、このしきい値(V0)を自動追従させて判定する演算処理の結果と比較する。【選択図】図2
