METHOD FOR RECEIVING SIGNALS FROM INDUCTIVE COUPLING LINE WITH COMPENSATION OF INTERFERENCE FROM TRACTION CURRENT AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2022 - IPC B61L25/06 

FIELD: railway automation.

SUBSTANCE: inventions group relates to railway automation and telemechanics, namely to methods and means for receiving signals from an inductive coupling line with compensation for interference from traction current. The method consists in additionally continuously calculating the sum of the EMF induced in each of the sensors from interference; calculate the value of the sum of the interference asymmetry coefficient in the inductive coupling line and the asymmetry coefficient of the geometric position and electrical parameters of the receiving coils and/or Hall sensors as a percentage of the resulting interference EMF to the sum of the EMF induced in each of the sensors from interference; measuring before the first wheelset of the railway rolling stock by induction method and/or using the Hall effect by means of at least one sensor the electromagnetic field near the conductor or conductors of the contact network; determine the EMF level of interference compensation by adjusting the level of EMF interference induced from the conductor or conductors of the contact network, in accordance with the calculated sum of the interference asymmetry coefficient in the inductive communication line and the asymmetry coefficient of the geometric position and electrical parameters of the receiving coils and/or Hall sensors; subtracting from the sum of the resulting interference emf and the useful signal the magnitude of the interference compensation emf; the result is transmitted to the input of the locomotive receiver.

EFFECT: decrease in the number of failures in the operation of on-board equipment of automatic locomotive signaling in the presence of asymmetry in the inductive coupling channel.
