METHOD OF RECEIVING SIGNALS FROM INDUCTIVE COMMUNICATION LINE WITH COMPENSATION FOR INTERFERENCE FROM POWER EQUIPMENT OF ELECTRIC ROLLING STOCK Russian patent published in 2024 - IPC B61L3/12 

FIELD: electricity.

SUBSTANCE: invention relates to methods of receiving signals from an inductive communication line with interference compensation. In the method, the electromagnetic field is continuously measured by an inductive method and/or using the Hall effect near the location area of at least one current receiving sensor, located above the left-hand running rail, using at least one current measuring sensor; electromagnetic field is measured by an inductive method and/or using the Hall effect near the area of arrangement of at least one current receiving sensor located above the right-hand running rail, using at least one current measuring sensor; measuring the interference level at one or more frequencies different from the frequency band of the useful signal induced in at least one current receiving sensor located above the left-hand running rail; measuring the interference level at one or more frequencies different from the frequency band of the useful signal induced in at least one current receiving sensor located above the right-hand running rail; determining transmission coefficients for one or more interference frequencies for each of the current receiving sensors; determining the level of interference for one or more interference frequencies in each of the current measuring sensors; continuously generating for each of the current receiving sensors, taking into account the calculated transmission coefficient and the signal transmission delay, the compensation voltage for one or more interference frequencies; compensation voltages for each of the receiving current sensors are summed up and the obtained sum is subtracted from the sum of the resultant voltages of the useful signal and interference voltages obtained for the receiving current sensors.

EFFECT: reduced interference level at locomotive receiver input related to operation of electric rolling stock power equipment.
