Background

Forest fires continue to emerge endlessly. According to the website information of the emergency administration, 1153 forest fires occur in 2020 all the year around, wherein 7 forest fires are significant, and 8526 hectares of damaged forest areas are generated. Because the forest environment provides a lot of combustible materials, and is located outdoors, the wind helps the fire, so the forest fire is characterized by fast development speed and great difficulty in fighting fire. In the past, after an isolation zone is established, a fire truck often puts out a fire from a distance, or an unmanned aerial vehicle is adopted to carry a fire extinguishing bomb to extinguish a fire from the upside. However, such a fire extinguishing method is time-consuming and expensive, and the advantage of extinguishing the fire when the fire is not developed at the initial stage of the fire cannot be understood. Therefore, many industry people have made relevant researches on intelligent fire monitoring and timely fire extinguishing.

Application number CN 202010533485.6's patent has proposed a forest fire prevention that can intelligent control fire hydrant carries out the scope and has put out a fire is with isolation barrier, carries out the condition of a fire monitoring through smoke transducer and the temperature sensor that dress inlayed, controls the fire hydrant shower nozzle and carries out the scope after judging the condition of a fire takes place and put out a fire. However, the accuracy of sensor monitoring is only a temporary matter, and the sensor monitoring cannot judge the development trend and the size of the fire. Meanwhile, the range fire extinguishing may also occur due to insufficient water power, which may result in the failure of effective fire extinguishing. Patent application No. CN201910740987.3 proposes an intelligent forest fire prevention system. This system has a plurality of sub-monitoring ends, and its built-in a plurality of sensors of accessible, image module and positioner know fire situation position and image information etc. put out a fire the aspect and be the fire control monitoring end that has the staff to hold and send the instruction, go out to move unmanned aerial vehicle and put out a fire. In addition to this, a personal terminal is provided to notify nearby residents. But the system needs to be controlled by the staff to give an alarm by the fire-fighting unmanned aerial vehicle. Meanwhile, the patent mentions that the information of the sub-monitoring end is comprehensively evaluated by the main monitoring end and then transmitted to the fire-fighting monitoring end, but how to process the information is not clear. Patent application No. CN201910775457.2 proposes a GIS-based forest fire prevention command and dispatch system, which mainly aims at finding fire and dispatching fire extinguishing force. This system sets up a plurality of monitor points in the forest, shoots the image through visible light camera and infrared camera, is furnished with multiple sensor simultaneously, judges whether the condition of a fire appears in many respects. In the aspect of rescue force scheduling, however, the staff still needs to coordinate according to the feedback information.

Therefore, the following technical defects exist in the forest fire prevention aspect at present:

in the aspect of forest fire recognition, the prior art mostly relies on sensors such as temperature and smoke for recognition, images are generally only used as references, the images are less reprocessed and utilized, only two-dimensional information of a fire scene can be obtained, and insufficient judgment of the fire condition and the fire behavior is easily caused.

At present, in the field of forest fire fighting, fire extinguishing equipment mainly improves a fire truck and an unmanned aerial vehicle, and the research on an automatic fire extinguishing device based on visual control is less; meanwhile, the fire condition is accurately identified by combining with the accurate control of fire-fighting water flow, so that the fire-fighting water power is fully utilized, and more effective fire extinguishment is realized.
