A recently granted patent (Publication Number: US11873016B2) details a sensor device designed for monitoring sounds emanating from the wheels of a railroad vehicle to detect anomalies. The device includes an audio sensor, a CPU for processing sound data, and a transmitter to send signals indicating wheel anomalies. The system can be expanded to include multiple sensor devices on different railroad vehicles forming a mesh wireless network, all communicating with a master controller in the lead locomotive to issue alerts in case of detected anomalies.
Furthermore, the patent describes a sensor device that can be mounted on a railroad vehicle to monitor sounds from various components, not limited to wheels, to detect anomalies such as broken wheels, damaged axles, or bearings. The device utilizes audio signatures to filter out non-anomaly sounds and compares the data with known sounds to identify anomalies. It includes features like accelerometers, receivers, and timing devices for accurate monitoring and communication of detected anomalies, ensuring timely alerts and maintenance actions to prevent potential failures in the train system.
