Mountain fire image identification method of image monitoring system of electric transmission line tower

Abstract

The invention discloses a mountain fire image identification method of an image monitoring system of an electric transmission line tower. The mountain fire image identification method comprises the following steps that firstly, the forest fire danger rating is evaluated by means of data of a microclimate on-line monitoring system on the electric transmission line tower, and the image collecting frequency of the on-line monitoring system is adjusted according to rating evaluation; secondly, abnormal situations of an image are detected by the image difference principle; thirdly, skyline segmentation is conducted on the image; fourthly, whether the image has a flame region is judged; fifthly, whether the image has a smoke region is judged; sixthly, whether a fire occurs is judged. The mountain fire image identification method has the advantages that remote early warning of mountain fire of an electric transmission line is achieved, and safe and stable operation of the electric transmission line of an electric system is guaranteed.

Description

technical field [0001] The invention relates to an image recognition technology for on-line monitoring of transmission lines, in particular to a mountain fire image recognition method for a power transmission line tower image monitoring system. Background technique [0002] At present, the early warning of wildfires in China mostly uses forestry department personnel to patrol and rent high-altitude aircraft to monitor. There are problems such as limited monitoring scope and time, high cost, and being easily affected by climate conditions, making all-weather monitoring impossible. The Ministry of Forestry rented two satellites from the National Oceanic and Atmospheric Administration of the United States to monitor wildfires in my country in the form of infrared imaging, but they can only scan designated areas 4 times a day, and the early warning of wildfires lacks timeliness. [0003] Domestic companies mostly use smoke sensors to provide early warning of wildfires in the onl...

AI Technical Summary

Problems solved by technology

[0002] At present, the early warning of wildfires in China mostly uses forestry department personnel to patrol, rent high-altitude aircraft monitoring and other means, all of which have the problems of limited monitoring scope and time, high cost, vulnerable to climatic conditions, and unable to carry out all-weather monitoring

The Ministry of Forestry rents two satellites from the National Oceanic and Atmospheric Administration of the United States to monitor wildfires in my country in the form of infrared imaging, but they can only scan the designated area 4 times a day, and the early warning of wildfires is not timely.

[0003] Domestic companies mostly use smoke sensors to provide early warning of wildfires in the online monitoring of wildfires near transmission lines. However, due to the influence of natural factors such as wind force and direction, atmospheric smoke and dust, the correct recognition rate is low

The reliability of the smoke sensor will be reduced if it is exposed to the wild area for a long time
