Forest fire prevention comprehensive supervision method and system

Abstract

The invention discloses a forest fire prevention comprehensive supervision method and system, and relates to the technical field of forest fire prevention, and the method comprises the steps: building an omnibearing forest fire prevention system through the combination of four modes of video monitoring, key area bayonet monitoring, unmanned aerial vehicle flight and satellite monitoring; meanwhile, technical prevention and civil air defense are combined, four defense lines of forest fire prevention are built, and a new situation of intelligent grid forest fire prevention application is created. According to the invention, the forest fire intelligent identification capability is improved, all-year-round and all-weather efficient intelligent identification early warning is achieved, and the effects of automatic scanning, automatic discovery, automatic analysis, automatic early warning and automatic order sending of the fire behavior in the visible range of the forest fire prevention area are realized.

Description

technical field [0001] The present application relates to the technical field of forest fire prevention, in particular to a comprehensive supervision method and system for forest fire prevention. Background technique [0002] In China, the core points of forest fire prevention business are "prevention" and "fighting". "Prevention" means preventing fires caused by natural factors such as terrain, temperature, temperature, wind, precipitation, and human factors such as production and living fires. "Firefighting" means that the forestry fire prevention department organizes manpower and material resources to extinguish the fire. If the forest fire is too fierce, manpower cannot put it out, and we can only wait for the forest fire to extinguish itself, which often causes immeasurable harm and loss. [0003] But now, traditional forest fire prevention is gradually being replaced by modern forest fire prevention: In traditional forestry, fire prevention is only to reduce economic...

Problems solved by technology

[0004] At present, in addition to traditional manual patrolling, satellite remote sensing is also used for forest fire prevention. However, the advantage of domestic Fengyun meteorological satellite remote sensing technology is that it can accurately detect and report on large areas of excessively high temperature points, and at the same time, it can be almost unaffected. Weather affects data collection, and it is not affected by terrain. It can monitor all-weather and all-time, but there are the following shortcomings: First, due to the limitation of satellite spatial resolution and time resolution, it is impossible to achieve all-weather real-time coverage, especially the area cannot be found. Smaller initial fires cannot be monitored through the clouds in the sky; second, satellite transit monitoring hotspots are usually only monitored once every two or three hours, and most of the monitored hotspots have already formed fires or even formed fires, and the monitoring effect is relatively low. Lag; Third, due to monitoring tasks, the National Fire Administration now only processes images with more than 2 pixels, one pixel is not processed for hotspots in fires or hotspots, and the image processing lags (0.5 to 1 hour), especially for cloudy weather in the south , In the case of many small fires, the effect of forest fire monitoring is reduced
