Problems solved by technology

For example: "A method for detecting foreign objects intruding on high-voltage lines" (application number: 2014104849.X), although image processing technology is used to detect foreign objects, it does not distinguish what kind of foreign objects pose threats to transmission lines
"Intelligent video online monitoring and evaluation system for foreign matter intrusion on power transmission lines" (application number: 201610661214.2), although it mentions the type of foreign matter, it lacks specific identification methods and strategies, and lacks certain pertinence

Embodiment Construction

[0025] The technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention.

[0026] see figure 2 One embodiment of the identification method for mountain fire intrusion in the transmission line channel of the present invention includes the following steps:

[0027] Step 1. Extract multiple frames of images from the monitoring video of the transmission line channel; extracting multiple frames of images from the monitoring video mainly considers the frequency of image sampling. For forest fire disasters, the occurrence of mountain fires is mainly concentrated in winter and autumn. The probability of wildfires is small. Therefore, in response to this feature, we carried out a strategy of sampling multiple times a day in an environment with drought and less rain according to the local meteorological conditions. Secondly, according to statistics, most of the mountain fires are cau...

Abstract

The invention provides an identification method for mountain fire invasion in a transmission line channel. The method comprises the steps that first, multiple frames of images are extracted from a monitoring video of the transmission line channel; second, morphological filtering and de-noising processing are performed on the extracted images; third, a motion analysis method among the images is utilized to capture a motion object in the images, and a region of the motion object is extracted from the images; and fourth, characteristic discrimination is performed on the captured motion object, and a mountain fire has several obvious characteristics. According to the method, whether the motion object is a mountain fire is determined through step-by-step extraction of the color, motion characteristics, area change rate, flickering frequency and sharp corner characteristics of the detected motion object, and therefore the accuracy of mountain fire identification is greatly improved.

Description

technical field [0001] The invention relates to the technical field of smart grids, in particular to a method for identifying wildfire intrusion in transmission line channels. Background technique [0002] According to the statistics of State Grid Corporation's operation data over the years, the tripping rate of lines caused by wildfires in overhead transmission line channels remains high, accounting for the main position of power transmission and transformation equipment failures. For a long time, the competent authorities have believed that the operation and maintenance of transmission line channels is mainly a management problem, and usually use manual squatting and crowd protection to deal with it, which consumes a lot of manpower and material resources, and the effect is poor. There are also monitoring equipment such as video and radar installed on the pole tower, and the accuracy and reliability cannot be guaranteed by manually identifying defects, which is not conduci...
