To provide a new technique for determining a state of an alternating current track circuit.SOLUTION: A track circuit state determination device 100 comprises measuring terminals 200 installed in a section boundary of track circuits and a processing unit 300. The processing unit 300 calculates a transmitting current vector with respect to a transmitting voltage for each track circuit and classifies the calculated current vectors into those in a period when a train is on the track and those in a period when the train is not on the track. And the processing unit determines a state of the track circuit including at least one of a normal state or an abnormal state by comparing loci of the current vectors in the respective periods with reference vector loci based on past current vector loci for the track circuits.SELECTED DRAWING: Figure 1
【課題】交流軌道回路の状態を判定する新たな技術を提供すること。【解決手段】軌道回路状態判定装置100は、軌道回路の区間境界に設置された計測端末200と、処理装置300とを備える。処理装置300は、軌道回路毎に、送信電圧に対する送信電流の電流ベクトルを算出し、算出した電流ベクトルを、列車在線時の期間と列車非在線時の期間とに区分する。そして、各期間の電流ベクトル軌跡を、当該軌道回路についての過去の電流ベクトル軌跡に基づく参照ベクトル軌跡と比較することで、正常状態か異常状態かを少なくとも含む軌道回路の状態を判定する。【選択図】図1
