Abstract
A system and method for monitoring the operating condition of a wheelset on a railcar comprising a sealed unit mounted on or near a wheelset of the railcar for collecting data from the wheelset and performing AI analyses on the collected data to determine the operational condition and predict failure modes for the wheelset. Results are communicated off-railcar wirelessly via one or more of several different methods.
Claims33
A method for operating a wireless sensor node deployed on a railway asset, comprising:
- receiving, by a processor, vibration sensor data from one or more vibration sensors and bearing temperature data from a temperature sensor;
- performing, by the processor, wheelset health check operations comprising:
- using the vibration sensor data as an input to a machine learning model that is trained to detect vibration patterns predictive of future failures of both a bearing portion of the wheelset and a wheel portion of the wheelset;
- and
- in the case that none of the vibration patterns were detected by the machine learning model, using the bearing temperature data as another input to the machine learning model that is trained to detect a fault or defect in the bearing portion of the wheelset;
- and
- altering, by the processor, a behavior of the wireless sensor node based on a result from performance of the wheelset health check operations.
4 more elements
A wireless sensor node, comprising:
- an enclosure configured to be mounted on a wheelset of a railway asset;
- one or more vibration sensors configured to measure vibrations associated with the wheelset;
- a temperature sensor configured to measure temperatures associated with the wheelset;
- a wireless communication system configured to wirelessly transmit a signal;
- and
- a circuit that is disposed in the enclosure and configured to perform wheelset health check operations comprising:
- using vibration sensor data as an input to a machine learning model that is trained to detect vibration patterns predictive of future failures of both a bearing portion of the wheelset and a wheel portion of the wheelset;
- and
- in the case that none of the vibration patterns were detected by the machine learning model, using bearing temperature data as another input to the machine learning model that is trained to detect a fault or defect in the bearing portion of the wheelset;
- wherein a behavior of one or both of the wireless communication system and the circuit is altered based on a result from performance of the wheelset health check operations.
