In the prior art, when the forest monitoring device is installed, the forest monitoring device is difficult to monitor after the forest is adjusted in a comprehensive angle, so that a detection result generates certain errors, the accuracy is reduced, and the emergency notification to a background system and the timeliness are lacked.

Forest fires are one of eight natural disasters in the world, have strong burst property, great destructiveness, high danger and extremely difficult disposal, seriously endanger the safety of people's lives and properties and forest resources, and even cause ecological disasters. China is a country which is short of forests, green and fragile in ecology as a whole, and is affected by monsoon and has multiple forest fires. Eighteen great parties of the Party bring ecological civilization into five-in-one overall layout of Chinese characteristic social career, clearly put forward to vigorously promote the construction of the ecological civilization, strive to construct beautiful China, and realize the sustainable development of Chinese nationality.

But in general, the forest fire prevention work in China is still at a lower level, and the fire occurrence frequency still keeps a certain state. The causes of forest fires are mainly as follows:

1) combustible materials in the forest: the forest type mostly belongs to secondary forests with large combustible load, forest facies are incomplete, and vegetation mainly comprises pines, Chinese silvergrass and the like. It can be said that the material base condition for forest fire occurrence is completely satisfied. Particularly, in recent years, along with implementation of national ecological public welfare forest construction projects and gradual increase of mountain sealing and forest cultivating strength, the canopy density of forest trees is gradually increased, forest vegetation is rapidly thickened, and combustibles in the forest are rapidly increased.

2) Climate conditions: along with the change of global climate, the extremely severe weather is gradually increased, so that the large-area disaster of forest resources is caused, part of forest land is disastrous, and the combustible substances in the forest are quickly thickened, so that the fire risk level of the forest is high.

3) A field fire source: from regional distribution, the fire sources are more concentrated around cities and towns, along highways, on field sides and other places. Seasonal fires and perennial fires can be distinguished in time. The seasonal fire sources mainly include fire for production, picnic, heating up graves and burning paper, burning incense, putting firecrackers, lighting candles and the like, and are relatively concentrated in the spring and autumn fireproof period; perennial fire sources mainly refer to fire sources for fire in forest areas throughout the year, such as living fire of mountain people living in mountainous areas, catering industry fire in scenic tourism areas, fire species carried by motor vehicles in forest areas, aging of electric wires and the like.
