Flat wheel detector with multiple sensors

摘要

The present disclosure is directed to a flat wheel detector. The flat wheel detector may have a first sensor configured to be located adjacent a rail of a railroad track. The first sensor may be oriented at a first angle relative to a horizontal plane. The flat wheel detector may also have a second sensor configured to be located adjacent the rail. The second sensor may be oriented at a second angle relative to the horizontal plane. In addition, the flat wheel detector may have a controller in communication with the first and second sensors. The controller may be configured to receive signals from the first and second sensors. The controller may also be configured to detect a flat wheel on a railroad car based on the signals.

1. A flat wheel detector, comprising:
a first sensor configured to be located adjacent a rail of a railroad track, the first sensor being oriented at a first angle relative to a horizontal plane; a second sensor configured to be located adjacent the rail, the second sensor being oriented at a second angle relative to the horizontal plane; a speed detector located adjacent the railroad track and configured to generate a signal indicative of a speed of a railroad car travelling on the railroad track; and a controller in communication with the first sensor, the second sensor, and the speed detector, the controller being configured to:
receive signals from the first sensor, the second sensor, and the speed detector;adjust a threshold for a flat wheel condition based on the signal indicative of the speed; anddetect a flat wheel on the railroad car when a parameter based on at least one of the signals received from the first sensor and the second sensor exceeds the threshold.
