Forest fire monitoring and early warning system and method, storage medium and computer equipment

Abstract

The invention belongs to the technical field of forest fire monitoring and early warning, and discloses a forest fire monitoring and early warning system and method, a storage medium and computer equipment. The method comprises steps of using L1-level data information of a scanning radiometer carried by a wind cloud meteorological satellite; extracting fire points at different moments by using a fixed threshold method; dynamically tracking and monitoring a fire process by using a visual discrimination method to realize the positioning of an ignition point; normalizing vegetation index data byusing a scanning radiometer carried by a wind cloud meteorological satellite, correcting a forest fire risk index formula, making a forest fire risk weather grade relative to the first three days of afire hazard by combining local meteorological data, and analyzing a corresponding relationship between the fire risk weather grade and the forest fire hazard. The forest fire hazard early warning system has great significance in forest fire hazard monitoring and forest fire hazard early warning, effective information is provided for forest fire extinguishing command decision making, and scientific reference is provided for related decision making or service departments.

Description

technical field [0001] The invention belongs to the technical field of forest fire monitoring and early warning, and in particular relates to a forest fire monitoring and early warning system, method, storage medium and computer equipment. Background technique [0002] At present, as one of the important components of the earth's ecosystem, the forest is an important ecological guarantee for the survival and development of human beings and various organisms. Forests not only provide material resources for human survival and development, but also play an important role in maintaining ecological processes and ecological balance, especially in protecting fresh water resources, conserving water sources, and purifying water quality. However, forest fires will bring serious harm to the forest. Forest fires not only destroy the vegetation coverage in the forest, but also cause water and soil erosion. At the same time, they will also destroy the carbon reserves in the forest and cha...

AI Technical Summary

Problems solved by technology

[0005] Most of the forest resources on the earth are distributed in remote and remote mountainous areas with few people. When a fire breaks out, it is difficult to detect and fight fires.

Traditional monitoring methods include watchtower monitoring, manual patrol monitoring and aircraft patrol monitoring, etc., but these methods have great limitations, and the monitoring consumes huge manpower, material and financial resources, and is also affected by various natural factors; when forest fires When the smoke generated is relatively large, it is difficult for the watchtower in the forest area to confirm, so conventional monitoring methods cannot guarantee timely detection of fires
