Classification: CPC B  G | IPC B  G

Claim 6:
7. A system for monitoring wheels of a train as the train moves along a track, the system comprising:
a first sensor device mounted on a first railroad vehicle of the train, the first sensor device including:
a first audio sensor configured to (i) monitor sounds emanating from a first portion of a plurality of wheels of the train as the train moves along the track and (ii) generate a first set of sound data associated with the monitored sounds emanating from the first portion of the plurality of wheels;
a CPU configured to generate based on audio signatures included in the first set of sound data, filtered sound data, wherein portions of the first set of sound data having audio signatures associated with track sounds are removed from the filtered sound data and determine, based on the filtered sound data, if a wheel anomaly sound is present within the first set of sound data;
a first transmitter configured to transmit a first broken wheel signal responsive to a determination that a portion of the first set of sound data is indicative that a first one of the first portion of the plurality of wheels is broken; and

a second sensor device mounted on a second railroad vehicle of the train, the second device including:
a second audio sensor configured to (i) monitor sounds emanating from a second portion of the plurality of wheels of the train as the train moves along the track and (ii) generate a second set of sound data associated with the monitored sounds emanating from the second portion of the plurality of wheels; and
a second transmitter configured to transmit a second broken wheel signal responsive to a determination that a portion of the second set of sound data is indicative that a first one of the second portion of the plurality of wheels is broken.
