Embodiment Construction

[0027] Hereinafter, specific embodiments of the present application will be described in detail with reference to the accompanying drawings. According to these detailed descriptions, those skilled in the art can clearly understand the present application and can implement the present application. Without departing from the principle of the present application, the features in different embodiments can be combined to obtain new implementations, or some features in certain embodiments can be replaced to obtain other preferred implementations.

[0028] see Figure 1~4 , the application provides a forest fire early warning method, at first obtain the satellite map of the forest area to be monitored, collect the forest area topographic and landform data, vegetation type and coverage and the temperature over the years (T i ), air humidity (H i ), wind speed (V i ) and other information. According to the obtained information, find out the fire risk areas in the forest area, includ...

Abstract

The invention belongs to the technical field of environmental protection, and particularly relates to a forest fire early warning method. A traditional early warning method is high in adaptation degree to a flat land with a gentle terrain or a slope land with high directivity, but effective fire early warning is difficult to make for the undulating landform of a complex mountain terrain area. The invention provides a forest fire early warning method, and the method comprises the steps: designing an irregular grid according to the landform of a complex mountain terrain region, arranging spherical early warning devices on each vertex of the grid from low to high, and carrying out the control and operation through an early warning center after the arrangement is completed. Each early warning device transmits monitored information such as temperature Ti, air humidity Hi and wind speed Vi to the early warning center at fixed time intervals t, and the early warning nodes transmit information sensed by the nodes mutually. The problem that detection is not easy when a forest fire occurs in a complex mountain terrain area can be effectively solved. Installation is convenient, equipment is convenient, and operation is convenient.

Description

technical field [0001] The application belongs to the technical field of environmental protection, in particular to a forest fire early warning method. Background technique [0002] At present, forest resources are important national resources, and forest fires have burned a huge area of ​​forests, which is one of the important reasons for destroying forest resources. At the same time, forests are part of ecological construction. Effective prevention of forest fires is also out of the need to protect the lives and property of people in forest areas, and is also conducive to promoting national forestry ecological construction. The protection of both primary and re-established forests can provide important support for the protection of forest resources. [0003] Most forests are located in a complex environment with large undulations and large relative height differences. Forest fires in such environments are easily affected by the terrain, spread quickly and are difficult to...
