Fixed and mobile combined forest fire prevention and control method and system

The invention discloses a fixed-movable combined forest fire prevention and control method and system, and the method comprises the steps: carrying out the fire protection inspection through a large-range multispectral scanning imaging forest fire detection device under a conventional condition, and carrying out the secondary confirmation through an unmanned plane after a fire behavior is found; meteorological information and position information of a fire area are acquired through the meteorological acquisition device and the Beidou/GPS positioning device, and early forest fire is extinguished by using the dry powder fire extinguishing bomb. According to the invention, a large-range multispectral scanning imaging forest fire early detection technology is adopted, and the characteristic of strong maneuverability of the unmanned aerial vehicle is combined, so that the forest fire can be detected and confirmed in time, the forest fire response speed and processing efficiency are improved, and fire loss and casu
