Real-time detection of wheel anomalies

摘要

A computer-implemented method includes receiving, by one or more sensors, data for one or more cycles, each of the one or more cycles including one or more slots. The computer-implemented method further includes combining the one or more slots from each of the one or more cycles into a combined slot group. The computer-implemented method further includes converting the combined slot group into a converted slot group. The computer-implemented method further includes monitoring the converted slot group for an anomaly. The computer-implemented method further includes, responsive to the anomaly: Comparing the anomaly to one or more known anomalies to determine a correlation between the anomaly and the one or more known anomalies, and determining the anomaly location. The computer-implemented method further includes reporting a problem condition based on at least one of the correlation and the anomaly location. A corresponding computer system and computer program product are also disclosed.

1. A computer-implemented method comprising:
receiving, by one or more sensors, time domain signal data for one or more cycles, each of said one or more cycles comprising one or more slots; combining said one or more slots from each said one or more cycles into a combined slot group; converting said combined slot group into a converted slot group, wherein converting said combined slot group into said converted slot group comprises transforming said time domain signal data to frequency domain signal data to yield said converted slot group; monitoring said converted slot group for an anomaly; responsive to said anomaly:
comparing said anomaly to one or more known anomalies to determine a correlation between said anomaly and said one or more known anomalies;determining a location of said anomaly; andreporting a problem condition based on at least one of said correlation and said location of said anomaly.
