Paper Abstract

This paper presents an optical device for uninterrupted non-contact temperature measurements and detection of overheated bearing of train. The pair of proposed optical devices is suitable to be mounted along the same axis as wheel axle on both railway sides. The optimum position for optical devices mounting is 0.5m above the rail tracks level. The proposed method is based on remote infrared measurement of lid surface of axle bearing. The device consists of three parts: optical part, infrared detector and processing unit. This paper presents characteristics of used lenses and optical filter. The output signal waveforms depend on train speeds. Proposed optical device are shown to have a vital role in: keeping railroad operations safe, preventive maintenance and avoiding of damaging of axle wheel bearing in railway.
