Abstract
A wheel slide detection system with at least one device, such as a camera, to capture an image of a wheel, and a processor to receive the captured image, identify the wheel, and to analyze the relative position of the wheel to determine whether or not the wheel is rotating. The system can detect rotation, non-rotation or partial rotation of the wheel. The camera(s) can be triggered by sensor-activation or microprocessor-activation. A visible or electronically encoded feature or marker on the wheel can be used as a reference for establishing wheel rotation. A processing algorithm can compare the location of the feature or marker on consecutive images to assess rotation of the wheel by determining an angle of rotation of the wheel.
Claims28
A railway vehicle wheel slide detection system including:
- an image capture means to capture a plurality of images of a wheel;
- and
- a processing means to receive at least two of said captured images, identify said wheel and analyze the at least two images, detect at least one component, feature, or marker on the wheel, whether a part of the wheel or added to the wheel, and compare the relative positions of the at least one component, feature or marker in said at least two images to detect a difference in position of the at least one component, feature or marker to determine whether said wheel is rotating or not rotating.
A method of detecting railway vehicle wheel slide, comprising:
- capturing a plurality of images of a wheel of the vehicle;
- analyzing the at least two images;
- detecting at least one component, feature, or marker on the wheel, whether a part of the wheel or added to the wheel;
- and
- comparing the relative positions of the at least one component, feature or marker in said at least two images to detect a difference in position of the at least one component, feature or maker to determine whether said wheel is or is not rotating.
