Forest, known as the lungs of the earth, is the basis for the sustained, rapid and healthy development of the entire national economy. It has an irreplaceable position and role in the national economic construction. However, these precious resources can be torched by relentless forest fires in an instant. Forest fires have become the greatest threat to the construction of ecological civilization and the safety of forest resources. Forest fire is harmful and difficult to extinguish, so it is particularly important to extinguish it immediately when the fire is still in its infancy.

Forestry resources

Modern forestry urgently needs to establish and improve forest fire prevention early warning and forecasting system and command and dispatch system
With the development of information technology, forest fire prevention work needs to make full use of high-tech forest fire monitoring technology and remote command and dispatch system, establish more advanced forest fire prevention command center, in order to realize forest fire "early prevention, early detection, early rescue" and "early, small, hit".
Forestry fire early warning is not timely and difficult to locate
Because forest fires are often located in old forests in deep mountains, it is difficult to find them. How to find forest fires in time, locate the fire location accurately, and carry out systematic early warning at the first time are the main purposes of forest fire prevention information system construction.
Traditional forest protection has small scope and low efficiency
Traditional artificial forest protection has low efficiency, high coverage and high cost of human resources. It is necessary to enhance the efficiency and results of forest protection by means of information technology.

Forest fire prevention

Through years of investigation and technology accumulation, Yungan Internet of Things and Hubei Forestry Research Institute jointly developed forest fire early warning as the core starting point, based on integrated forest fire prevention geographic information system, using infrared thermal imaging thermal induction technology and intelligent pyrotechnics detection algorithm, automatic monitoring and early warning of forest resources within several kilometers, with the help of intelligent forest fire awareness. Other technologies can monitor, locate and alarm forest fires. Through the assistant decision-making system of forest fire prevention, the whole process of "pre-disaster, mid-disaster and post-disaster" in three-dimensional scene, all-round and integrated dynamic control and decision-making support platform are realized, which provides technical support and scientific basis for decision-making of forest fire risk detection, early warning, forecasting, fire fighting and post-disaster evaluation, and builds an intelligent fire prevention system.
Comprehensive Application of One Graph
The system highly integrates video surveillance, fire warning, three-dimensional fire location, assistant decision-making, command and dispatch systems to realize the efficient integrated management and application of "one map".
Fully automatic fire warning and accurate positioning
Using infrared thermal imaging technology, automatic cruise and early warning of fire points within several kilometers are carried out, and precise location of fire points is realized by combining with three-dimensional GIS geographic information system.
Highly centralized and precise scheduling
The system is highly integrated with command and dispatch functions. Through GIS map, the forest fire control command center can make accurate allocation of fire trucks, firefighters and forest rangers to achieve a comprehensive understanding and unified allocation of the fire fighting force of the whole fire site.
Core front-end equipment
The front-end camera for monitoring and detecting fire hazards is a long-range thermal imaging camera based on the latest 5th generation uncooled infrared technology and continuous zoom infrared optical technology. The uncooled focal plane imaging detector with high sensitivity 336X256 resolution is adopted.

Forestry Bureau of Yangxin County Forest Fire Prevention Monitoring and Early Warning System

The construction project of forest fire prevention monitoring and early warning system of Yangxin County Forestry Bureau under the construction of Yungan Internet of Things takes intelligent forestry as the core theme. According to the construction idea of "less investment, more integration, more practical effect and strong application", in the aspect of forestry fire prevention, auxiliary checkpoints, forest fire monitoring system and general monitoring are constructed to realize 24-hour active management of forest area conditions. When disasters occur, the monitoring center can use intelligent fire prevention monitoring system, GIS rapid fire location, assistant decision-making system and emergency command and dispatch system to minimize disaster losses and comprehensively improve the protection level of Yangxinye.
