System for monitoring track transportation
First Claim
1. A system for monitoring a track transportation, comprising:
- at least one sensing module arranged at a predetermined monitoring point of the track, each sensing module comprising;
at least one force sensing unit for detecting a force signal generated from a vehicle passing through a predetermined monitoring point of the track where the force sensing unit being arranged, and accordingly generating a time domain force-related signal;
at least one vibration sensing unit for detecting a vibration signal generated from a vehicle passing through a predetermined monitoring point of the track where the vibration sensing unit being arranged, and accordingly generating a time domain vibration-related signal;
a track status signal processing circuit electrically connected to the sensing module for receiving the time domain force-related signal detected by the force sensing unit so as to convert to a digital frequency domain force-related signal, and receiving the time domain vibration-related signal detected by the vibration sensing unit so as to convert to a digital frequency domain vibration-related signal; and
a signal calculating and processing unit electrically connected to the track status signal processing circuit for receiving the frequency domain force-related signal detected by the force sensing unit and the frequency domain vibration-related signal detected by the vibration sensing unit so as to convert to an input-output response frequency spectrum signal.

Abstract
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.
