METHOD FOR CONTROLLING RAIL LINE STATES WITH END CROSSPIECES Russian patent published in 2018 - IPC B61L23/16 

FIELD: transportation.

SUBSTANCE: invention relates to the field of railway automatics and telemechanics for monitoring the states of a rail chain. In the method, a rail line is used, devices of the supply and receiving ends, a capacitor connected via a transformer to the rail threads, where the serviceability and freedom of the rail line is estimated by the voltage at the input of the receiver, which should exceed the threshold value. Moreover, the ends of the rail line are short-circuited by crosspieces, by means of rail sections, together with capacitors and path transformers, form parallel oscillatory circuits, in which a current resonance arises at the frequency of the signal current, that creates a high resistance between the points of connection of devices to the rail thread, connect the devices of the supply and receiving ends to these points, cyclically instead of the segments of the rails of one rail thread, connect similar segments of another rail thread, control of the release of the track section is carried out after the passage of the train during the interaction of the carload and track inductors.

EFFECT: higher reliability of the rail chain is achieved.
