A forest fire monitoring system and method

Abstract

The invention relates to a forest fire monitoring system and method. It includes a server, a main UAV and an auxiliary UAV; the server is used to: obtain the first image of the forest area calibration area collected by the main UAV, and the main UAV flies at the first height; When it is determined that there is a fire in the calibration area, control multiple auxiliary UAVs to the calibration area, so that multiple auxiliary UAVs and the main UAV form a polygonal array to fly, and fly together at the second height, which is lower than the second height. a height; obtain multiple consecutive second images collected by the main UAV and each auxiliary UAV at the second height respectively, and the second images collected by adjacent UAVs at least partially overlap; according to all the second images Determine the trend information of the fire area and the center of the fire. The technical scheme of the present invention can facilitate timely and reasonable and targeted fire-fighting and disaster-relief work in forest areas, so as to reduce corresponding losses.

Description

technical field [0001] The invention relates to the technical field of Internet of Things applications, in particular, to a forest 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, afforestation should be carried out to increase the forest coverage, and on the other hand, the existing forests should be protected from fire and insects. [0003] Forest fires are the enemy that endangers forests. A fire can turn a large area of ​​forest into ashes in the blink of an eye, causing serious losses. At the same time, the forest land loses its forest cover, which is easy to cause soil erosion, and is prone to floods, droughts, and sand disasters. affect agricultural production. Therefore, fire monitoring in forest areas is required. [0004] If the forest area ...

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.
