摘要： A method detects the presence of a vehicle on a railway track using a sensing processor monitoring a sensing system for detecting vibration into ground installed along the railway track. The sensing system includes a detection module for detecting a vehicle on the railway track. The method includes an initialization step which includes the sub-steps of emitting a first signal to be received by the sensing processor through the sensing system, sending a first message to the sensing processor, monitoring the sensing system, and configuring the detection module in function of the received first signal and configuration data received in the first message. The configuration data can include location of the initialization device, intensity/magnitude of the first signal, emission time of the first signal, and/or type of object corresponding to the first signal.

摘要： 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.
