Problems solved by technology

However, in the monitoring of mountain fires on power transmission lines, pure infrared monitoring is susceptible to interference from high temperature factors such as solar beams, and it is easy to fail to identify mountain fires because the flames are blocked.
Smoke-based video surveillance is of great significance for early detection of fires, but the recognition of wildfires based solely on smoke is interfered by atmospheric clouds and fog, and the false alarm rate is high

Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with specific embodiments.

[0021] The method for monitoring wildfires on transmission lines combining smoke and infrared recognition in this embodiment includes the following steps:

[0022] (S1) Collect video images of the area to be monitored in real time, and select the next step according to whether the current collection time is day or night, if the current collection time is daytime, go to step (S2), if the current collection time is night, go to step (S3) ;

[0023] (S2) According to the 2 to 3 frames of video images continuously collected in the area to be monitored, a Gaussian mixture model is used to model the video images to obtain a background model, and the collected video images are used to update the background model, and then the background model is used to The subsequent video image is subjected to foreground detection to obtain the pre-detection result of wild fire during the da...

Abstract

The invention discloses a power transmission line mountain fire monitoring method integrating smoke and infrared identification linkage. The method comprises the steps of: collecting a video image ofan area to be monitored in real time, obtaining a daytime mountain fire pre-detection result based on a Gaussian hybrid model or obtaining a night mountain fire pre-detection result based on an adaptive threshold algorithm according to the current collection time, obtaining an infrared fire discrimination result of the area to be monitored according to an collected infrared image of the area to bemonitored, collecting an onsite mountain fire image in the case of fire, and then performing area marking by using an image communication area marking algorithm to obtain an accurate location of a smoke and fire area. By adopting the power transmission line mountain fire monitoring method, the discovery time of the mountain fire can be shortened, and the mountain fire monitoring accuracy can be improved.

Description

Technical field [0001] The invention relates to the technical field of electric power engineering, in particular to a method for monitoring wildfires on transmission lines that integrates smoke and infrared recognition linkage. Background technique [0002] Wildfires on transmission lines are mainly caused by fires of combustibles (including trees, thatchs, structures, flammable and explosive materials, etc.) existing under the lines and in the protection area, which damages or malfunctions the lines. The main forms are mountain fires, house fires, and accumulations (coal, wood, plastic, etc.) fires. Because poor control is easy to spread after a fire occurs, it is easy to cause line tripping, and it is difficult to restore the normal operation of the line in a short time. Current transmission line wildfire monitoring methods are mainly based on infrared monitoring technology, such as the development of ground-based infrared monitoring, airborne infrared forest fire monitoring a...
