Abstract
A system for detecting a moving hot bearing or wheel of a rail car is provided. The system includes a first comparator to receive input signals representative of radiation emitted by the moving hot rail car bearing or wheel, and to compare the input signals to a threshold value. The system further includes a counter for counting incidents of the input signals exceeding the threshold value and a second comparator to compare a number of incidents of the input signals exceeding the threshold value to a count threshold as an indication of detection of a hot rail car bearing or wheel.
Claims16
A system for detecting a moving hot bearing or wheel of a rail car comprising:
- a first comparator configured to receive input signals representative of radiation emitted by the moving hot rail car bearing or wheel, and to compare the input signals to a threshold value;
- a counter configured to count incidents of the input signals exceeding the threshold value;
- and
- a second comparator configured to compare a number of incidents of the input signals exceeding the threshold value to a count threshold as an indication of detection of a hot rail car bearing or wheel.
A system for detecting a moving hot bearing or wheel of a rail car comprising:
- sensors disposed adjacent to a rail for detecting the radiation emitted by the moving hot rail bearing or wheel;
- a first comparator configured to receive input signals from the sensors representative of radiation emitted by the moving hot rail car bearing or wheel, and to compare the input signals to a threshold value;
- a counter configured to count incidents of the input signals exceeding the threshold value;
- and
- a second comparator configured to compare a number of incidents of the input signals exceeding the threshold value to a count threshold as an indication of detection of a hot rail car bearing or wheel.
