METHOD OF CONTROLLING TRACK STATE Russian patent published in 2013 - IPC B61L23/16 

FIELD: transport.

SUBSTANCE: invention relates to railway equipment, namely, to railroad ACS and telemetry hardware and be used for traffic control. Proposed method comprises feeding variable voltage to track line input to be compared with threshold magnitudes of occupation and disengagement. First receiver is used to control current voltage of the first supply source at track line input end. In case it drops below threshold track occupancy is registered. Simultaneously, second receiver at circuit input end to register threshold clearing magnitude and to control current voltage of second power supply. In case current voltage of threshold magnitude exceeds clearing threshold, track clearing is registered. To register integrity of track lines, smooth change in voltage from second power supply is controlled. Besides, synchronism of operation of second receiver microelectronic units is controlled.

EFFECT: higher reliability of track state control.
