摘要： The present disclosure is directed to a system and method for identifying a hot bearing. A processor may be configured for receiving a plurality of infrared (IR) signals emitted by a bearing as the bearing passes through a view window being monitored by one or more IR sensing elements positioned to receive IR radiation emitted from a target area of the bearing. The processor may extract IR data from IR signals emitted from an area within the target area of the bearing defined by a narrow window extending along a longitudinal axis for a length corresponding to substantially an entire length of the bearing. The processor may also establish a characteristic thermal profile from the extracted IR data, the characteristic thermal profile exhibiting identifiable boundaries of an area of interest on the bearing. The processor may compare temperatures of the bearing within the area of interest to a threshold, and produce an alarm signal if temperatures of the bearing within the area of interest exceed the threshold.

摘要： The present disclosure is directed to a method for detecting a condition associated with a wheel bearing on a train car. The method may include detecting a size and a location of the wheel bearing. The method may also include detecting a temperature associated with the wheel bearing based at least in part on the size and the location of the wheel bearing. The method may further include determining a wheel bearing condition based on the detected temperature.

摘要： A system for detecting a temperature of a railroad train wheel or bearing includes a thermal line scanner and a processor. The thermal line scanner is positioned to capture a plurality of thermal line scans of the wheel or bearing. The processor is configured to analyze each of the plurality of thermal line scans, identify a selected line of the plurality of thermal line scans, and calculate the temperature of the wheel or the bearing based on the selected line. Thus, the system and method disclosed herein reduce the acquired thermal data first to a single line for one or both of the wheel temperature and bearing temperature and then to single values.
