Forest fire monitoring system and method

Abstract

The invention relates to a forest fire monitoring system and method. The system comprises a server, a main unmanned aerial vehicle and auxiliary unmanned aerial vehicles. The server is used for acquiring a first image of a forest calibration area acquired by the main unmanned aerial vehicle, and the main unmanned aerial vehicle flies at a first height; when it is determined that a fire occurs in the calibration area according to the first image, controlling the multiple auxiliary unmanned aerial vehicles to move to the calibration area, arranging the multiple auxiliary unmanned aerial vehiclesaround the main unmanned aerial vehicle to jointly fly at a second height lower than the first height; acquiring a second image acquired by the main unmanned aerial vehicle and a third image acquiredby each auxiliary unmanned aerial vehicle, wherein the second image partially coincides with each third image, and the third images acquired by the adjacent auxiliary unmanned aerial vehicles partially coinciding with each other; and determining change trend information of the fire center according to the second image and the third images. According to the technical scheme, the fire range, the dynamic change of the fire behavior center and other conditions can be accurately determined, and more accurate reference information is provided for fire extinguishing and disaster relief work.

Description

technical field [0001] The invention relates to the technical field of Internet of Things application, in particular to a forest fire monitoring system and method. Background technique [0002] In order to improve the ecological environment, afforestation activities are widely carried out, whether it is a natural reserve forest area or a forest farm, the scale and area have a tendency to gradually expand. Since forest areas or forest farms are threatened by fire, it is necessary to monitor forests in forest areas or forest farms. [0003] At present, the main method of fire monitoring is manual observation of watchtowers, but this will be affected by many factors such as the external environment, and forest fires still occur from time to time. After the fire has occurred, it is necessary to take corresponding measures in a timely manner. However, if the fire spreads rapidly and the smoke is large, it will be impossible to obtain accurate fire information only by relying on ...

[0003] At present, the main method of fire monitoring is manual observation of watchtowers, but this will be affected by many factors such as the external environment, and forest fires still occur from time to time

After the fire has occurred, it is necessary to take corresponding measures in a timely manner. However, if the fire spreads rapidly and the smoke is large, it will be impossible to obtain accurate fire information only by relying on long-distance observation, which will affect the follow-up fire fighting and disaster relief work, and cause extreme disasters. Big ecological and economic loss
