Device for detecting excessively heated components or locations in moving objects
First Claim
1. A device for detecting the temperature of components of moving rail vehicles, comprising:
- an infrared beam detector and optical devices for directing infrared beams from separate points on said components to the detector, said optical devices including;
a separate lens associated with each of said points for directing beams of infrared radiation from said points to respective separate locations on an image-correcting system; and
a scanning device positioned between the image-correcting system and said detector for periodically scanning said locations and directing the respective beams onto said detector; and
a reflective area located on said image-correcting system for reflecting an infrared reference beam received from said detector back to the detector.

Abstract
In a device for detecting excessively heated components or locations in moving objects, in particular in moving rail vehicles, such as bearings, brakes and/or wheel rims, having at least one infrared beam detector (7) and optical devices for representing the image of the measuring point on the infrared beam detector (7), a separate lens (1, 2) is aimed toward each measuring point, which focuses the image of the measuring point on different points (4, 5) of an image-correcting system (3), and a scanning device (9), which periodically picks up the measuring beams, is disposed between the image-correcting system (3) and the detector (7) and focuses the measuring beams onto the detector (7) which is common to all measuring points.
