Transmission line wildfire satellite monitoring method based on background information

Abstract

The invention provides a transmission line wildfire satellite monitoring method based on background information. The method includes the steps of obtaining recognizing scene original data original monitoring images through preprocessing, wherein the recognizing scene original data original monitoring images are obtained by an MODIS satellite receiving station and include bright temperature values and reflection rates a first channel, a second channel, a third channel, a seventh channel, an eighth channel, a ninth channel, a twenty-first channel and a thirty-first channel; recognizing potential fire points, and endowing the first channel, the second channel and the seventh channel with the blue color, the green color and the red color respectively to generate a three-channel synthesis image; recognizing open fire points, smog points and low-temperature fire points, comparing coordinates of industrial and urban information of the open fire points, the low-temperature fire points and a transmission line geographic information system, removing the open fire points and the low-temperature fire points in industrial areas and urban areas, and obtaining the fire points still influencing a transmission line after removal according to a transmission line graph. By means of the method, the wildfire fire points near the transmission line can be automatically, rapidly and accurately recognized, the high capacity of recognizing the low-temperature fire points is achieved, the false alarm rate of abnormal high-temperature points can be decreased, the wildfire prevention and control work is guided, the tripping operation is avoided, and important guarantees are provided for power grid safety.

Description

technical field

[0001] The invention relates to the technical field of electrical engineering, in particular to a background information-based satellite monitoring method for mountain fires in power transmission lines. Background technique

[0002] In recent years, with global warming, extreme weather has occurred frequently, and the central and southern regions of my country are more and more prone to continuous high temperature and sunny weather during spring plowing and Qingming period. At the same time, due to economic development, traditional dry grass and trees have been replaced by gas in rural areas, coupled with the implementation of the policy of returning farmland to forests, the vegetation in mountainous areas has become more and more intact, so wildfires occur frequently. Since transmission line corridors often pass through mountainous areas and agricultural areas, the number of wildfires near transmission lines is increasing rapidly, and the number of trips due...
