System for monitoring track transportation

摘要

A system for monitoring track transportation to determine an abnormal status of a track is disclosed. The system includes at least one sensing module arranged at a predetermined monitoring point of the track, and each sensing module includes at least one force sensing unit and vibration sensing unit. A track status signal processing circuit is electrically connected to the sensing module for receiving the time domain force-related signal and time domain vibration-related signal, and these signals are converted to the digital signals. The digital signals are transferred to a signal calculating and processing unit, which includes a time domain/frequency domain force-related signal converting circuit, a time domain/frequency domain vibration-related signal converting circuit, and a frequency response function calculating unit. The frequency response function calculating unit divides the frequency domain vibration-related signal into frequency domain force-related signal to generate an input-output response frequency spectrum signal for determining an abnormal status of the track.
