Patent ID: 8155808

Claim:
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.
