Early warning method and system based on satellite data fusion mountain fire monitoring and fire behavior deduction

Abstract

The invention relates to an early warning method and system based on satellite data fusion mountain fire monitoring and fire behavior deduction. The method comprises the following steps: firstly, acquiring a fire point position in a target area by utilizing processed and analyzed meteorological hot spot data, outputting a forest fire monitoring and early warning file according to a vegetation classification condition at the target position, issuing early warning information, and forming a forest fire risk distribution thermodynamic diagram according to forest fire historical data; meanwhile, inputting the monitored longitude and latitude of the fire point into the fire behavior deduction module, judging the fire behavior development speed and direction comprehensively according to the weather, landform and land cover data of the fire point position, and outputting and publishing the fire behavior development range within the set time. The forest fire condition of the target area can bemonitored in a large-scale and all-weather mode through the satellite remote sensing technology, the neutral period existing in manual on-site observation can be made up, early warning is conducted in the early stage of forest fire development, the forest fire spreading range is deduced and predicted, and first-hand data information is provided for forest fire protection and related departments to take measures.

Description

technical field [0001] The invention relates to the technical field of mountain fire monitoring and fire deduction, in particular to an early warning method and system based on satellite data fusion for mountain fire monitoring and fire deduction. Background technique [0002] Under the trend of global warming, the probability of wildfires is gradually increasing. In addition, my country has a vast territory and complex terrain. It is difficult to achieve the purpose of comprehensive monitoring of wildfires only through manual monitoring. Currently, watchtowers, artificial field observations, and drones are used to monitor wildfires. Carrying out mountain fire monitoring by means of patrolling cannot achieve uninterrupted monitoring of all areas at all times and in all directions. As a result, some mountain fires develop rapidly without any measures being taken, and the development trend of mountain fires cannot be grasped in time. Cause incalculable loss of life and property....

[0002] Under the trend of global warming, the probability of wildfires is gradually increasing. In addition, my country has a vast territory and complex terrain. It is difficult to achieve the purpose of comprehensive monitoring of wildfires only through manual monitoring. Currently, watchtowers, artificial field observations, and drones are used to monitor wildfires. Carrying out mountain fire monitoring through cruises and other methods cannot achieve continuous monitoring of all areas in all directions at all times, resulting in the rapid development of some mountain fires without any measures being taken, and the development trend of mountain fires cannot be grasped in time. Incalculable loss of life and property
