System for detecting sliding of a wheel travelling along a track
First Claim
1. A system for detecting the sliding of a wheel travelling along a track comprising:
- a roller rotatable about a rotation axis, said roller disposed adjacent said track so that a wheel travelling along said track engages said roller and causes the roller to rotate about said rotation axis;
a rotation sensor associated with said roller for providing a rotation signal representative of the degree of rotation of said roller; and
a processor for calculating the degree of rotation of said roller from said rotation signal and comparing said degree of rotation with a pre-determined range of degrees of roller rotations and providing a signal indicative of sliding of said wheel when said degree of rotation of said roller is outside said pre-determined range.

Abstract
A system 10 for detecting sliding of a wheel 12 on a rail 14 includes a roller 16 disposed adjacent the rail 14 so that a wheel 12 travelling along the rail 14 can engage the roller 16, and a tachometer 18 coupled with the roller 16 for providing a rotation signal representative of the degree of rotation of the roller. The system 10 includes a computer 20 which receives the rotation signal from the tachometer 18 and by using an appropriate rotation algorithm calculates the degree of rotation of the roller 16. The computer 20 then compares the degree of rotation with a predetermined range of roller rotations and, if the calculated degree of rotation of the roller is less than predicted by analysis, the apparatus 10 provides a signal indicative of the wheel 12 sliding.

24. A method for detecting the slipping or sliding of a wheel traveling along a track comprising:
-
providing adjacent to the track, a roller rotatable about an axis of rotation, the roller being disposed so that a wheel traveling along the track engages the roller; providing to a processor a rotation signal representative of a degree of rotation of said roller; operating the processor to calculate the degree of rotation of the roller from said rotation signal and comparing the degree of rotation with a pre-determined range of roller rotations to provide a signal indicative of the wheel sliding when the degree of rotation is less than said pre-determined range, and providing a signal indicative of the wheel slipping when said degree of rotation is greater than said pre-determined range.
