MONITORING SYSTEM OF TREAD SURFACE OF RAILWAY WHEEL PAIR Russian patent published in 2013 - IPC B61K9/12 

FIELD: measurement equipment.

SUBSTANCE: invention refers to measurement equipment and is intended for automatic monitoring of technical state of railway rolling stock during its operation. Monitoring system of tread surface of wheel of railway wheel pair includes two groups of sensors of dynamic loads, sensors of monitoring zone, group of temperature sensors of crushed-stone ballast, an interface unit and a comparison unit. The system also includes direct Fourier transformation units, a calculation unit of average amplitude-frequency characteristics, units of the first correction of amplification coefficients, units of the second correction of amplification coefficients, a correction unit of amplification coefficients of dynamic load sensors, at the point of application of external force to the sensors, and an inverse Fourier transformation unit.

EFFECT: improving reliability of determination of defective wheel pairs.
