Description

Technical Field

[0001] The present invention relates to the technical field of wildfire monitoring, and in particular to a wildfire hotspot identification and positioning system in high altitude areas. Background Art

[0002] The climate in high altitude areas is dry, with relatively little precipitation, low air humidity, and low moisture content in vegetation, which makes vegetation easy to burn. For example, in some high altitude grasslands or alpine forests, long periods of drought can cause a large accumulation of flammable materials such as dead grass and fallen leaves. Once they encounter a fire source, such as sparks caused by lightning, unextinguished cigarette butts or campfire embers from human activities, they can easily cause wildfire hotspots. In addition, high altitude areas are often windy. Strong winds can accelerate air flow, provide sufficient oxygen for wildfires, and help the spread of fires, causing hotspots to expand rapidly and form larger-scale fires.

[0003] Therefore, due to the special geographical environment and climatic conditions in high-altitude areas, once a wildfire occurs, it has the characteristics of rapid fire spread, great difficulty in extinguishing, and serious damage to the ecological environment. Traditional wildfire monitoring methods face many challenges in high-altitude areas, such as limited range of manual observation and monitoring, and great influence of terrain and weather; satellite remote sensing monitoring has problems such as low resolution, low sensitivity to small fire points, and data transmission delay. Therefore, there is an urgent need for a system that can quickly and accurately identify and locate wildfire hotspots in high-altitude areas to improve the efficiency of wildfire monitoring and prevention. Summary of the invention

[0004] 1. Technical issues to be solved

[0005] In view of the shortcomings of the prior art, the high-altitude area wildfire hotspot identification and positioning system of the present invention can carry out comprehensive and accurate wildfire monitoring in high-altitude areas through a combination of a multi-source data acquisition module, a variety of monitoring equipment, infrared thermal imaging equipment, high-definition visible light cameras, positioning sensors and meteorological sensors. The system sets up multiple monitoring equipment on a fixed base station, divides the high-altitude area into multiple grids based on the location and monitoring range of the base station, and measures the distance between each grid and the base station, thereby achieving accurate positioning; the system uses multiple comparative analysis modules to confirm the authenticity and spread trend of suspected wildfire hotspots through comparative analysis of infrared thermal imaging data and high-definition visible light images, ensures real-time data transmission through the data transmission module, and can respond to external commands for system control; at the same time, the alarm module automatically classifies warnings according to the location and environmental sensitivity of the wildfire hotspot and pushes SMS, emails or sound and light alarms and other methods to notify relevant personnel, thereby effectively improving the wildfire prevention and emergency response capabilities in high-altitude areas.
