초록

A method and apparatus are disclosed for sensing the temperature of bearings of vehicles traveling along a track, the apparatus including a linear-array infrared detector positioned adjacent to the track. The output from the linear-array infrared detector is scanned at a scanning rate that is regulated according to the vehicle\s velocity, and this output is compared to predetermined thresholds to indicate excessive heat produced by the wheels and/or bearings.
