Abstract
A sensor device includes an audio sensor and a wireless communication module. The audio sensor is configured to be mounted on a railroad vehicle. The audio sensor is configured to (i) monitor sounds emanating from one or more wheels of the railroad vehicle as the railroad vehicle moves along a track and (ii) generate sound data associated with the monitored sounds emanating from the one or more wheels. The wireless communication module is configured to transmit a broken wheel signal responsive to a determination that a portion of the generated sound data is indicative that a first one of the one or more wheels is damaged or broken.
