At present, the temperature measurement pictures of infrared thermometers commonly used at home and abroad all use manual methods for infrared temperature measurement and atlas analysis. However, a large number of input work in the traditional sense seriously occupies the working time of operation and maintenance personnel, and the work efficiency is low., time-consuming and labor-intensive. The purpose of this paper is to provide a substation infrared detection method and system to solve the problems of low work efficiency, time-consuming and labor-intensive, and randomness of the existing substation infrared detection technology, which is not conducive to later analysis and judgment,
