Automatic check and early warning method and system based on infrared imaging temperature measurement for electric power equipment

Abstract

The invention discloses an automatic check and early warning method and a system based on infrared imaging temperature measurement for electric power equipment. According to the method, actual measurement temperature, environment temperature, humidity, wind speed, a present visible light video and infrared heat graphs of each detection area of the electric power equipment are acquired, and then trend analysis and prediction on an operation situation of the electric power equipment are carried out through actual measurement temperature threshold value analysis, conversion temperature threshold value analysis, single-phase or interphase temperature difference analysis and largest continuous load heat spot temperature prediction; sound-light early warning is carried out in combination with a warning threshold value according to the prediction values. The method takes intelligent check temperature measurement as the basis, through monitoring on temperature trend change information of the electric power equipment, the operation situation of the electric power equipment for a time segment in future can be predicted, and the early warning effect is realized.

Description

technical field [0001] The invention relates to a power equipment fault inspection and early warning method and system, in particular to an electric power equipment automatic inspection and early warning method and system based on infrared imaging temperature measurement. Background technique [0002] The existing infrared temperature measurement of electric power equipment mainly has the following methods: 1. Using a handheld thermometer; 2. Using an intelligent robot; 3. On-line monitoring. Hand-held thermometers are seriously affected by the professional quality of photographers and environmental conditions, and cannot monitor the operating status of power equipment in real time. The temperature measurement data cannot truly reflect the status of the equipment under specific environmental conditions; the temperature measurement of intelligent robots is not only affected by the environmental climate, but also At the same time, there are also problems in accurately locating...

Problems solved by technology

Hand-held thermometers are seriously affected by the professional quality of photographers and environmental conditions, and cannot monitor the operating status of power equipment in real time. The temperature measurement data cannot truly reflect the status of the equipment under specific environmental conditions; the temperature measurement of intelligent robots is not only affected by the environmental climate, but also At the same time, there are also problems in accurately locating the detection parts of the equipment; in addition, the methods of handheld thermometers and robots cannot achieve the purpose of automatic analysis and diagnosis of power equipment faults, and manual analysis by experts is needed, so faults cannot be found in time
