METHOD TO RECORD ROLLING STOCK WHEELSET TRAVEL THROUGH TRACK SECTION Russian patent published in 2017 - IPC B61L1/16 

FIELD: transportation.

SUBSTANCE: invention relates to the field of railway automatics and telemechanics, to record wheel travel. In the method they register variation of output voltages at the outlet of inductive sensors in real time, convert this data relative to distance in the form of voltage functions U1=f1(l), U2=f2(l), … Un=fn(l), then compare this data with a set of identical functions, which were previously entered into the memory of the controller during imitation of passage of the specific flanges of the wheel at some fixed distances from the surface and from the longitudinal axis of symmetry of the wheel travel registration sensor. Besides, using the produced functions, they establish the fact of travel of the wheel flange above inductive sensors and its diameter.

EFFECT: due to the invention, reliability of recorded wheel travel through a track section increases.
