METHOD OF CHECKING NON-OCCUPANCY OF TRACK CIRCUIT Russian patent published in 2003 - IPC

Abstract RU 2217336 C2

FIELD: railway transport; railway signaling and communication. SUBSTANCE: according to proposed method, current signal is supplied to track circuit. Level of signals is detected at receiving end and compared with threshold value of receiver. Current on supply end is limited by nonlinear resistor at changing of direction of transmission of said signal every second. EFFECT: improved reliability of track circuit. 1 dwg
