Abstract
A wheel integrity monitoring system for monitoring the integrity of a railcar wheel in an automated manner while the railcar is in operation (i.e., traveling) and comprising a light source that projects light onto the wheel and a light detector that detects the light reflected by the wheel. The wheel integrity monitoring system is configured to analyze the reflected light to determine if the wheel is defective.
Claims17
A railcar wheel integrity monitoring system, comprising:
- a. a light source for projecting a beam of light onto a wheel of a railcar travelling on a rail;
- b. a detector for sensing a reflection of the beam produced when the beam impinges on the wheel while the wheel is in motion on the rail;
- c. a control unit for receiving a signal from the detector conveying beam reflection information, the control unit configured to process the beam reflection information to detect a structural flaw in the wheel.
A railcar wheel integrity monitoring system, comprising:
- a. a light source for projecting a beam of light onto a wheel of a railcar travelling on a rail;
- b. a detector for sensing a reflection of the beam produced when the beam impinges on the wheel while the wheel is in motion on the rail;
- c. the light source and the detector being positioned relative to each other such that a structural flaw on a surface of the wheel scanned by the beam produces a modified reflection by comparison to a reflection produced when the wheel has no structural flaw;
- d. a control unit for receiving a signal from the detector conveying beam reflection information, the control unit configured to detect the modified reflection.
