Forest resources are one of the most important resources on the earth. They are the basis of biodiversity and one of the indispensable resources for human survival. With the development of the economy, the progress of society and the improvement of people's living standards, people's demands for the environment are getting higher and higher. Air quality and ecological environment directly affect the residents' health and quality of life, and directly affect the sustainable development of urban economy. Forests are playing an important role in purifying air, regulating climate, preventing soil erosion, maintaining species diversity and conserving water resources. Therefore, in order to expand the forest area, the government will devote a large amount of manpower, material and financial resources to afforestation every year. However, as the forest resources develop and grow, they are damaged to varying degrees. This kind of damage mainly comes from two aspects: on the one hand, it is man-made destruction, mainly because of the illegal cutting and illegal cutting by the lawless elements for the immediate interests. The losses caused by them are limited and controllable. On the other hand, natural disasters, such as diseases and insect pests, fires, and so on, cause huge losses, but there is a process of their development and spread, which can be effectively prevented. However, the losses caused by forest fires are huge, destructive and uncontrollable, and the occurrence is also random. To reduce the loss of forest resources to a minimum, disaster must be nipped in the bud.

Core technology -- Intelligent image pyrotechnic recognition algorithm
1. Raw data analysis
The algorithm uses uncompressed raw data to identify the smoke features quickly in the background of the image, so that the whole algorithm system is more than one level of betrayal, which improves the accuracy level of the algorithm and eliminates the missing report.

In addition, intelligent forestry ecological monitoring system and intelligent forestry resources supervision system can be realized. Automated logging, illegal inspection and supervision , Ecological data automatic acquisition, data display and analysis, forestry vegetation information management and other aspects. 1) automated logging, illegal inspection and supervision.
China's forest farms generally have a large area, and traffic and communication are inconvenient. It has increased the difficulty of logging and illegal construction supervision. At present, most of the forest farms are inspecting the forest farms by way of inspection teams. The inspection efficiency is low, the cycle is long, the information feedback is not in time, and the missing rate is high.
The intelligent forestry resource supervision system provides spatio-temporal data comparison technology to conduct regular inspections of forest farms, and makes automatic comparative analysis of remote sensing map data at different times, and automatically analyzes forest deforestation and illegal construction through the results of map differentiation.
2) automatic collection, display and analysis of ecological data in forest farms.
The ecological data of the forest farm are relatively abundant, including meteorological, environmental, soil and water quality. Most forest farms are backward in equipment, and data collection is carried out by means of traditional personnel acquisition. There is no unified platform for exhibition management, not to mention data analysis and utilization.
Ecological data collection
The intelligent forestry ecological monitoring system can automatically collect, centrally manage and analyze all kinds of ecological data in the forest farm by means of sensors such as hydrology, soil, environment and meteorology. It is not only conducive to the daily management and maintenance of forest farms, but also important to the development of forestry ecological information.
3) information management of forestry vegetation.
The division and management of vegetation in the forest farm still stays on the blueprint, which is not intuitive and inaccurate to the management of the forest farm, and can not record all the attribute information of the vegetation. It is not convenient for managers to grasp the overall macro control of Forest Farm vegetation.
The intelligent forestry resource monitoring system realizes the three-dimensional display, query and statistics of vegetation by vegetation information management, and displays all the attribute information of vegetation by clicking on different vegetation layers, and can achieve the statistics of area and quantity.
"The green tree village is close to each other, and the green hills and the Kuo are inclined outward." since ancient times, the beautiful natural environment is people's yearning. People are closely interlinked with nature. Through information technology, we have "dialogue" with every tree and every forest, accurately "perceive" their emotions, and understand their "food, clothing, shelter and shelter", so as to carefully care for every shade. Cloud sensing Internet of things The attempt is just a beginning, dare to innovate, dare to apply the "no man's land" to new technology, accelerate the construction of "intelligent forestry", and ecological forest will usher in unlimited scenery.
