Title:
TRACK CIRCUIT DEVICE AND TRAIN ON-TRACK DETERMINATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/204268
Kind Code:
A1
Abstract:
A track circuit device (1) measures a transmission voltage and a transmission current of an alternating-current signal transmitted to a rail, calculates an impedance equivalent value based on the amplitude and phase difference of the measured transmission voltage and transmission current, and determines that a train is on track on the basis of the values of a real component and an imaginary component of the calculated impedance equivalent value.
