A track circuit device (1) measures a transmission voltage and a transmission current of an AC signal transmitted to a track bar, calculates an impedance equivalent value on the basis of the amplitudes of the measured transmission voltage and transmission current and the phase difference between the transmission voltage and the transmission current, and determines an AC signal on the basis of the values of the real component and the imaginary component of the calculated impedance equivalent value. And judging whether the track section is occupied by a vehicle.

    轨道电路装置(1)对发送到轨条的交流信号的发送电压和发送电流进行测定,基于测定出的发送电压和发送电流的振幅以及该发送电压与该发送电流的相位差来计算阻抗等效值,基于计算出的阻抗等效值的实数成分和虚数成分的值,判定轨道区段是否有车占用。
