The three elements that affect fires

Temperature, humidity, and unit combustible load.

How to discover

Forest fires pose great harm and are difficult to extinguish, so it is particularly important to extinguish them immediately when they are still in their early stages.

Forest fires are often located in deep mountains and forests, making them difficult to detect. Therefore, discovering fires is of great significance for extinguishing them early.

There are still many technologically backward methods in China.

 

1. Built a watchtower

Observation tower monitoring is the process of observing forest fires through observation towers, determining the location of the fire, and reporting the fire situation. Its advantages are large coverage and good effectiveness. Shortcomings: Remote forest areas without living conditions cannot have observation towers; Its observation effect is limited by the terrain and topography, with small coverage, dead corners, and gaps that cannot be observed. It cannot observe large areas of fire, residual fires, and underground fires with heavy smoke; Thunderstorm weather makes it impossible to observe from the tower; Observation is a method that relies on the experience of an observer to observe, with low accuracy and large errors. In addition, the personal safety of the lookout is threatened by lightning, wild animals, forest encephalitis, and other factors.

 

2. Establish a video surveillance system

The current mainstream monitoring method in China.

This is a simple extension of traditional urban monitoring, which collects video images through microwave aggregation and manually completes centralized monitoring;

Manual monitoring can easily cause visual fatigue, making it difficult to detect fires in videos and resulting in missed reports;

There are many video lines in the monitoring center, and manual monitoring cannot monitor them one by one, which can easily lead to missed reports.

So, the biggest drawback of traditional video surveillance is the very high false alarm rate.

Traditional video surveillance is a non digital system that many intelligent applications cannot achieve.

 

3. Establish an intelligent warning system

This is the development direction of forest fire prevention, realizing the intelligence and informatization of forest fire prevention.

By utilizing seamless integration of intelligent image recognition technology, object-oriented 3D GIS technology, large-scale network monitoring technology and other high-tech, and utilizing multiple patented technologies, combined with professional knowledge of forestry management and experience in forestry fire prevention, a forestry fire prevention intelligent monitoring and early warning and emergency command system is established to achieve automatic monitoring of forest videos, accurate identification of fireworks, precise positioning of fire points, deduction of fire spread trends, auxiliary decision-making for firefighting command, post disaster assessment and other functions. A complete business chain for forest fire prevention is established, and various personalized needs of users are targeted to be solved.
