Forest fire behavior monitoring system and method

Abstract

The invention relates to a forest fire behavior 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, the multiple auxiliary unmanned aerial vehicles are controlled to the calibration area, the multiple auxiliary unmanned aerial vehicles and the main unmanned aerial vehicle form a polygonal array to fly and jointly fly at a second height, and the second height is lower than the first height; a plurality of continuous second images acquiredby the main unmanned aerial vehicle and the auxiliary unmanned aerial vehicles at a second height are acquired, wherein the second images acquired by the adjacent unmanned aerial vehicles at least partially coincide; and change trend information of an on-fire area and a fire center according to all the second images is determined. According to the technical scheme, reasonable and targeted forestfire extinguishing and disaster relief work can be conveniently carried out in time, so that corresponding losses are reduced.

Description

technical field [0001] The invention relates to the technical field of application of the Internet of Things, in particular to a forest area fire monitoring system and method. Background technique [0002] As the main body of renewable natural resources and terrestrial ecosystems, forests play an irreplaceable role in the survival and development of human beings. In order to protect the forest, on the one hand, it is necessary to carry out afforestation work to increase the forest coverage, and on the other hand, protective measures such as fire prevention and insect protection must be carried out for the existing forest. [0003] Forest fire is the enemy that endangers the forest. A fire can turn a large area of ​​forest into ashes overnight, causing serious losses. affect agricultural production. Therefore, fire monitoring in forest areas is required. [0004] If the forest area is large, the existing fire monitoring method in the forest area is mainly manual inspection...

AI Technical Summary

Problems solved by technology

[0004] If the forest area is large, the existing fire monitoring method in the forest area is mainly manual inspection on the watchtower. Although the fire can be found most of the time, if the wind is too strong, the smoke is too thick, etc., it will not be possible to further monitor the fire in time. Accurately obtaining fire information may delay the deployment of effective fire fighting and disaster relief work.
