Example Embodiment

[0013] Example 1. Such as figure 1 As shown, it includes an online infrared imaging thermometer, A / D converter and a monitoring computer. The online infrared imaging thermometer is used to take the infrared heat map of the power equipment at the detection point and output the infrared heat containing the temperature measurement value. Figure related infrared thermal image analog signal; A / D converter is used to convert the infrared thermal image analog signal output by the online infrared imaging thermometer into an infrared digital signal and transmit it to the monitoring computer; online infrared imaging thermometer connection A / D converter, the A / D converter is connected to the monitoring computer; the infrared imaging thermometer adopts a panoramic pan-tilt binocular camera, which has a visible light channel and an infrared channel, which can simultaneously shoot infrared heat maps and visible light images of electrical equipment. When measuring, such as figure 2 As show...

Abstract

The invention discloses an online accurate electric power equipment temperature measurement method and a system based on infrared imaging. An online infrared imaging temperature measurer is employed to measure temperature of electric power equipment, the electric power equipment is provided with at least two detection areas for measurement, the different detection areas are respectively provided with measured object radiation rates to correct a temperature measurement error caused by the radiation rate, and a problem of non-high temperature measurement precision caused by using one same radiation rate in a whole frame can be avoided. According to the method, the different detection areas of the electric power equipment are respectively provided with the measured object radiation rates to correct the temperature measurement error caused by the radiation rates, a crude correction mode of using the same radiation rate in the whole frame can be avoided, so precise temperature measurement on crucial parts of the electric power equipment is realized.

Description

technical field [0001] The invention relates to a temperature measurement method and system for electric power equipment, in particular to an infrared imaging-based online accurate temperature measurement method and temperature measurement system for electric power equipment. 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 At the same time, there are also problems in accurately locating the d...
