Abstract
A method for inspecting a rail vehicle includes receiving signals representative of temperatures of a wheel of the rail vehicle and generating a sensed wheel temperature profile of the wheel based on the signals. At least a portion of the sensed wheel temperature profile is representative of the temperatures of the wheel. The method also includes identifying waveform attributes in the sensed wheel temperature profile and designating the sensed wheel temperature profile as at least one of a typical wheel profile and an atypical wheel profile based on the waveform attributes in the sensed wheel temperature profile.

A method for inspecting a rail vehicle, the method comprising:
- receiving signals representative of temperatures of a wheel of the rail vehicle,
- generating a sensed wheel temperature profile of the wheel based on the signals, at least a portion of the sensed wheel temperature profile being representative of the temperatures of the wheel;
- identifying waveform attributes in the sensed wheel temperature profile;
- and
- designating the sensed wheel temperature profile as at least one of a typical wheel profile and an atypical wheel profile based on the waveform attributes in the sensed wheel temperature profile.
A rail vehicle inspection system comprising:
- a temperature sensor for sensing temperatures of a wheel of a rail vehicle, the temperature sensor generating signals representative of the temperatures;
- and
- a processor to receive the signals from the temperature sensor, the processor programmed to:
- generate a sensed wheel temperature profile, at least a portion of the sensed wheel temperature profile being based on a portion of the signals that are representative of the temperatures of the wheel,
- identify waveform attributes in the sensed wheel temperature profile, and
- designate the sensed wheel temperature profile as at least one of an atypical wheel profile and a typical wheel profile based on the waveform attributes.
A computer readable storage medium for a rail inspection system having a processor and a temperature sensor configured to sense temperatures of a wheel of a rail vehicle and to generate signals representative of the temperatures, the computer readable storage medium comprising instructions to direct the processor to:
- receive the signals from the temperature sensor;
- generate a sensed wheel temperature profile based on the signals, at least a portion of the sensed wheel temperature profile representative of the temperatures of the wheel;
- identify waveform attributes in the sensed wheel temperature profile;
- and
- designate the sensed wheel temperature profile as at least one of a typical wheel profile and an atypical wheel profile based on the waveform attributes.
A method for inspecting a rail vehicle, the method comprising:
- generating a sensed wheel temperature profile of a wheel of the rail vehicle, wherein the sensed wheel temperature profile comprises a plurality of respective temperatures of the wheel sensed at different locations of the wheel as the wheel passes a sensor during movement of the rail vehicle;
- identifying waveform peaks within the sensed wheel temperature profile, wherein the waveform peaks are identified when the temperatures in the sensed wheel temperature profile increase above a rising edge peak threshold then decrease below a failing edge peak threshold;
- and
- designating the sensed wheel temperature profile as a typical wheel profile if the waveform peaks meet at least one designated criterion and as an atypical wheel profile if the waveform peaks fail to meet the at least one designated criterion.
