Embodiment Construction

[0038] As described in the background technology, in the prior art, based on infrared thermal imaging technology to monitor mountain fires on transmission lines, as long as a high temperature area higher than the preset threshold is found, an early warning message will be issued, and ordinary high temperature objects such as industrial or residential fire points will also be issued. The accuracy of triggering an alarm to monitor wildfires on transmission lines is low. The technical solution of the present invention provides a method for early warning of mountain fires in transmission lines, and the method for early warning of mountain fires in transmission lines includes:

[0039] Select any area in the mountains and forests around the transmission line as the current monitoring area;

[0040] Acquiring an infrared thermal image of the current monitoring area;

[0041] Obtaining the high temperature area in the current monitoring area according to the infrared thermal image o...

Abstract

The invention discloses a method and a system for early warning electric transmission line wildfires. The method comprises the following steps of selecting any region in an electric transmission line surrounding mountain forest as a present monitoring region; collecting infrared thermographs in the present monitoring region; according to the infrared thermographs, acquiring a high-temperature region in the present monitoring region; continuously collecting the infrared thermographs with amount-defined frames in the high-temperature region; according to the infrared thermographs with the amount-defined frames, judging whether the temperature of the high-temperature region is changed; and when temperature and area of the high-temperature region are changed, sending out early warning information. According to the method and the system, industrial and resident fire point information are removed based on early performance characteristics of the wildfires, and thus the erroneous judgment probability of predicating the electric transmission line wildfires can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of transmission line monitoring, in particular to a transmission line mountain fire early warning method and system. 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 weather during spring plowing and Qingming. At the same time, due to the development of the economy, the rural fuels are replaced by traditional hay and trees for gas, and the policy of returning farmland to forests is implemented, and the vegetation in mountainous areas is becoming more and more well protected. Therefore, the number of wildfires near transmission lines is increasing rapidly, and the number of trips due to wildfires has also increased significantly. Even UHV lines have experienced tripping accidents due to wildfires, seriously threatening the safe and stable operat...
