Embodiment Construction

[0036] Attached below figure 1 The present invention is described in further detail. The present invention is a method for identifying mountain fires in transmission lines based on temperature distribution, and the specific implementation steps are:

[0037] Step 1, mountain fire monitoring image preprocessing;

[0038] For the received infrared images of mountain fire monitoring on transmission lines, the image Fourier transform method is used to realize the image enhancement processing, and the 3×3 median filter method is used to de-dry the image. The relevant processing flow of the above method is the prior art. I won't repeat them here. At the same time, for the above-mentioned processed monitoring image, the image color mode is converted from RGB mode to HIS mode, and the calculation formula is as follows:

[0039]

[0040] Among them, R, G, and B are the red, green, and blue components of the image, respectively, and H, I, and S are the hue, brightness, and saturat...

Abstract

The invention discloses a power transmission line mountain fire identification method based on temperature distribution. The power transmission line mountain fire identification method based on temperature distribution includes the following steps: 1) mountain fire monitoring image preprocessing and color mode conversion; 2) flame primary determination based on color characteristics; 3) mountain fire characteristic extraction based on color characteristic difference; and 4) mountain fire identification based on temperature distribution. The power transmission line mountain fire identification method based on temperature distribution can effectively identify the mountain fire areas in the images and can effectively exclude the interference factors, such as sunlight and car lights by considering the nonuniformity of temperature distribution in the flame areas. The power transmission line mountain fire identification method based on temperature distribution has the advantages of being clear in thinking, being convenient for operation, and being high in practicality, and can be widely applied to the field of power transmission line mountain fire monitoring and alarm.

Description

technical field [0001] The invention belongs to the technical field of electric power engineering, and in particular relates to a method for identifying mountain fires in transmission lines based on temperature distribution. Background technique [0002] With the continuous expansion of UHV lines and cross-regional power grids, more and more transmission lines pass through high mountains and mountains. When encountering continuous dry weather, large-scale wildfires are prone to erupt. In recent years, more than 50,000 wildfires have occurred in my country every year. The large-scale wildfires in the corridors of overhead transmission lines can easily cause multiple lines to trip, and even cause the collapse of large power grids. [0003] At present, the hotspot recognition technology based on infrared images has been widely used in the field of mountain fire monitoring on transmission lines. The mountain fire identification technology based on digital image processing can p...
