  • Statistical and trend analysis of railroad bearing temperatures
    Patent number: 6813581
    Abstract: A system is provided for tracking the wheel bearing temperatures of a train and selecting those that are statistically determined to be abnormally high, while eliminating from consideration, or otherwise categorizing those high temperature readings which are the result of other anomalous and non-anomalous conditions. The system determines the overall distribution of the bearing temperatures for both sides of a train at each wayside location. The bearing temperatures are ranked for comparison with the overall train distribution. Outliers are detected and characterized based on temperature patterns and previous history.
