Research On The Application Of Infrared Temperature Measurement Technology In Video Surveillance System Of Substation

The technical scheme combined IR detection and video surveillance is designedand developed for realizing remote, real-time and on-line infrared monitoring of thepower equipment's thermal information. Based on infrared theory, the temperaturemeasurement model is constructed, the influence of atmospheric transmittance isanalyzed and its simulation is completed, the temperature modification method isproposed to enhance the precision of temperature measurement. According to the actualdemand of power system, the improved infrared thermameter and the advanced videosurveillance system are adopt. The infrared thermameter has RS-485 serial interface andlaser-aiming system. The infrared temperature measurement function and the videosurvelliance function are effectively combined. By choosing the specific electricalequipement in the surveillance images, its temperature can be measured, stored andanalyzed in remote distance, and the fault information of the equipement can be found intime. This system realizes the remote, real-time, on-line monitoring of the powerequipment's visible images and thermal information.
