Problems solved by technology

[0011] In order to overcome the existing technology in the monitoring of forest fire prevention, a large number of cameras need to be deployed in the forest area, and the system cost is high. These cameras can only work in the case of better light, and cannot work at night or even in the case of low daytime illumination ;In the image analysis system of the monitoring center, it is impossible to distinguish the morphological characteristics of the cloud and fog in the forest area from the forest fire. Usually, manual identification and early warning are used. When a fire occurs, the fire alarm point cannot be determined in time, and the technology of understanding the geographical conditions of the fire alarm point Deficiency, the present invention provides non-refrigerated detector forest fire prevention system

By using the system provided by the invention, forest fire prevention monitoring can be finally handled round the clock through the coordination of all departments in all regions.

Description

technical field [0001] The invention relates to the field of security technology, in particular to a forest fire monitoring system, more specifically a non-cooling detector forest fire prevention system. Background technique [0002] Forests have the functions of air purification, soil consolidation and water conservation, maintenance of ecological balance, and provision of production resources. In recent years, sandstorms have occurred frequently in our country, and desertification has continued to intensify, which is closely related to the destruction of forests. Every year, a certain number of forest fires occur around the world. Forest fires are characterized by suddenness, uncertainty, and huge damage in a short period of time. Large-scale forest fires are often caused by invisible hidden fires. [0003] At first, humans used to build watchtowers to warn forest fires manually. In this way, only large forest fires can be found; later, for forest areas with high forest ...
