Device and method for precisely preventing and controlling forest fire in large scale

The invention relates to a device and method for precisely preventing and controlling forest fire in a large scale, and the device comprises a planning module which is used for carrying out the planned burn-off of a forest, an unmanned plane burn-off system which is used for carrying out the planned burn-off of the forest, an unmanned plane control module, and a wireless data transmission module. The unmanned aerial vehicle burning-off system comprises an unmanned aerial vehicle, a burner and a fuel supply mechanism, the unmanned aerial vehicle is remotely controlled through an unmanned aerial vehicle control module, a burning-off plan is installed to conduct burning-off operation on a forest, and a plurality of fireproof isolation belts are generated in the burning-off operation process of the forest. According to the method, large-scale precise fire prevention and control can be carried out on the forest, large-scale precise planned burning-off can be efficiently carried out on the forest, and therefore the
