Abstract
Official abstract text for this publication.
A test apparatus for testing an IR sensor of train undercarriage temperatures is disclosed. The IR sensor may be used to obtain infrared IR emission data by sensing a wheel or a wheel bearing of a rail vehicle. The test apparatus may comprise a heat emitter for supplying IR emissions at a reference temperature to the IR sensor. A support may support the heat emitter at a position spaced from the passage of the rail vehicle and in an orientation for directing the IR emissions at the IR sensor.
First claim
Opening claim text (preview).
What is claimed is: 1. A test apparatus for an IR sensor of a rail vehicle undercarriage component, the test apparatus comprising: a heat emitter for producing IR emissions at a reference temperature, the heat emitter includes a heat member having a black surface coupled to a resistor; and a support for supporting the heat emitter at a position spaced from the passage of the rail vehicle and in an orientation for directing the IR emissions at the IR sensor. 2. The test apparatus of claim 1 wherein the heat emitter comprises at least one high speed IR LED. 3. The test apparatus of claim 1 wherein the heat emitter comprises a plurality of high speed IR LEDs arranged in an array corresponding to an array of IR sensor elements in the IR sensor. 4. The test apparatus of claim 1 further comprising a plurality of heat emitters. 5. The test apparatus of claim 1 wherein the support is an upright frame spanning a rail track. 6. The test apparatus of claim 1 further comprising a test circuit connecting the heat emitter to a controller. 7. The test apparatus of claim 6 wherein the controller is connected to a wheel sensor.
