METHOD OF IDENTIFICATION OF RAIL RUNNING OBJECTS Russian patent published in 2006 - IPC B61L25/02 

FIELD: railway transport.

SUBSTANCE: proposed method comes to recording signals from two wheel pickups when they are intersected by wheelsets of train. Wheel pickups are arranged at preset fixed distance relative to each other whose value is less than minimum possible interaxle distance. At distance. At moment of intersection of first wheel pickup, passive receivers-transponders installed on train running units are irradiated by SHF signal, and pulse is formed to start master timer referring time counting system to running train. Data on structure of interaxle distances of wheelsets corresponding to definite types of running units and data on running units corresponding to codes recorded in memory of passive receivers-transponders are preliminarily recorded in memory of measuring device. Algorithms for determining in time location of passive receiver-transponder and speed and direction of train running are provided. Periodicity of recorded signals is restored in case of skip in recording of signal from wheel pickups and/or presence of false information. Train is identified basing of data from wheel pickups and passive receivers-transducers.

EFFECT: improved reliability of identification of running objects.
