Abstract:
A vibration monitoring system includes an acoustic device that outputs an analog signal to a fiber cable for calibration and location verification. The acoustic device utilizes GPS or communication from wayside bungalow equipment to verify GPS location or real-time clock information. The wayside bungalow contains communication equipment that interfaces with the acoustic device and relays health information to a sensing processor. The sensing processor is configured to detect the acoustic signal output by the acoustic device at a known location and verifies that the cable and device have not moved location by comparing the signal level received against a threshold stored in memory. When the threshold is exceeded, the sensing processor sends an alert that the fiber optic cable or acoustic device at the location have changed.
