DEVICE FOR CHECKING AUTOMATIC LOCOMOTIVE SIGNALLING TAKING INTO ACCOUNT ASYMMETRY IN INDUCTION COMMUNICATION CHANNEL Russian patent published in 2020 - IPC B61L3/08 

FIELD: physics.

SUBSTANCE: device comprises a first path, including: first and second rails and sleepers, a throttle transformer, adjustable resistances; multichannel signal and interference generator, first and second receiving coils, data input unit, a control unit, a connection unit, a measurement and analysis unit, a display unit and a memory unit, a movable platform and a movable platform drive. Device additionally includes the second path located on one side from the first path and consisting of the first and second rails of the second track and the sleeper of the second path, the throttle-transformer of the second path, the first and the second adjustable resistances of the second path. First and second rails of second path are connected through first and second controlled resistances of second path respectively to corresponding outputs of multichannel signal and interference generator, are inductively connected to first and second receiving coils, for transmitting signal current, second-path throttle-transformer having main and additional windings, is connected by primary winding with first and second rails, and additional winding is connected to corresponding output of multichannel signal and interference generator. Distance between axes of the first and second paths complies with requirements for design and maintenance of track superstructure.

EFFECT: higher level of noise immunity of automatic locomotive signaling due to consideration of asymmetry effect in inductive coupling channel created by traction current in tracks of adjacent tracks.
