FIELD: transportation, physics.
SUBSTANCE: method for detection of braked wheel pairs in rolling equipment in motion is based on recording power of IR (infrared) radiation from wheel elements within limits of strobe pulse of wheel pair pass fixation sensor located in one section with IR radiation receiver inclined at an angle of 90 degrees to road axis and comparing the amplitudes of thermal signals from wheel elements of one axle. Thermal signals minimums are determined within strobe pulses, current values of thermal signals amplitudes are measured in section of these minimums. According to results of these amplitudes comparison against preset value alarm system signal is generated to stop train for checking the condition of brake equipment. This provides identification of rims, disks and hubs overheating occurrences during train service braking in consequence of wheel pairs blocking when brake equipment is faulty.
EFFECT: improvement of brakes technical condition control reliability, reduction of causeless train delays due to control facilities indications of heated wheel elements IR radiation during service braking.
