Monitoring wheeled transport system; involves filtering out periodic signals from sensor signals, correlating with wheel rotation frequencies and comparing with fault state catalogue

摘要

The method involves detecting and monitoring the noise and vibration caused by the transport system using sound and vibration detectors, filtering out periodic signals, correlating them with the rotation frequencies of the wheels or periodic processes associated with the transport system, comparing the correlations with a catalogue of possible fault states and signaling the detected fault.
