8. A forest fire prevention and extinguishing method using the forest and grassland fire prevention and extinguishing apparatus as claimed in claim 5, characterized by comprising the steps of:
acquiring a thermal imaging image of a monitoring area by a thermal imaging double-spectrum camera;
judging whether a fire disaster exists according to the temperature distribution condition of the thermal imaging image;
if a fire exists, acquiring video image data at the same spatial position as the thermal imaging image;
controlling the horizontal rotating mechanism and the vertical rotating mechanism to drive the water cannon to act and determining an ignition point;
if the ignition point is within the spraying range of the water cannon, starting the water cannon to aim at the ignition point to extinguish the fire;
and if the ignition point is not in the spraying range of the water cannon, starting the water cannon to spray water to form an isolation belt.
9. A forest fire prevention and extinguishing method as claimed in claim 8, further comprising the step of obtaining humidity information of the forest area, and when the humidity information reaches a set threshold value, starting a water cannon to spray water, so as to increase the humidity of the forest area.
10. A forest fire prevention and extinguishing method as claimed in claim 9, further comprising the steps of monitoring a specific area in real time by an ultraviolet sensor, and transmitting a fire signal to the controller and the background after the specific area is found to be on fire;
after receiving a fire signal, the controller and the background send an instruction to the thermal imaging dual-spectrum camera, and the thermal imaging dual-spectrum camera acquires a thermal imaging image of a monitoring area; and meanwhile, the vertical rotating mechanism and the horizontal rotating mechanism are controlled to drive the water cannon to act, signals are fed back to the controller and the background after the ignition point is determined by the horizontal flame sensor and the vertical flame sensor, and the controller and the background control an electromagnetic valve on the water cannon to be opened to spray water.
