Description
Technical field
The present invention relates to technical field of security and protection, particularly a kind of forest fire supervisory system, is more specifically uncooled detector Forest Fire Prevention System.
Background technology
Forest has air purification, fixing of soil and conservation of water, maintain the ecologic equilibrium, the effect of the resources of production is provided.In recent years, China's sandstorm takes place frequently, and desertification constantly aggravates, and this and forest suffer to destroy close contacting.Every year, can there is the forest fire of some in the whole world.The feature that forest fire has is sudden, uncertain, the short time is caused huge breaking-up, large-area forest fire, is caused by unconspicuous hidden fire often.
At first, the mankind adopt Jian sightseeing tower, the mode early warning forest fire of Yong Ren Gong lookout, and this mode, can only find larger forest fires; Afterwards, the forest zone to high forest fire danger class, adopted the early warning of cruising in the air, the cost costliness of cruising in the air, adds that the climate that cruises, the factor impact such as are round the clock larger, can not take on monitoring task for 7 * 24 hours, owing to cruising apart from the distance on earth's surface, be difficult to too find hidden fire or little fire in the air; At present, some large forest zones of China generally adopt satellite monitoring, but satellite is away from earth surface and condition of a fire generation area, and it conventionally only in 1000 square meters left and right, is difficult to find that there is hidden fire and the little fire that may cause forest fire to the resolution of temperature; Adopt conventional warming, the cigarette propagated sensation sensor of urban fire control to carry out early warning forest fires, because space, forest zone is large, environmental facies are to badly, and the cost that meets forest zone condition equipment is high, and this equipment is difficult within the scope of large space, carry out magnanimity deployment, is not suitable for forest fire protection.
In recent years, the video frequency monitoring system based on visible ray has been installed in many forest zones by China, is used for making up artificial loud and clear prestige, cruises in the air, the deficiency of means in forest fires early warning such as satellite monitoring.This system, according to the geographical features in forest zone, is divided into different guarded regions by forest zone, and the high point of part at each guarded region, arranges control point, and a common point can be monitored the forest scope of 90,000 mu of left and right.
This video frequency monitoring system based on visible ray, comprise the visible light camera, the sender unit that are arranged on control point, be arranged on signal receiving device, the video image processing system of Surveillance center, visible light camera is by the real-time forest zone video image photographing, by network, send to the Surveillance center of far-end, Surveillance center is analyzed the feature of the characteristics of image of acquisition and fire image, thereby finds hidden fire and little fire in forest.This video frequency monitoring system based on visible ray, has overcome to a certain extent artificial loud and clear prestige, has cruised in the air, the monitoring means such as satellite monitoring has been in the technological deficiency of finding on hidden fire and little fire.There is following defect in this video frequency monitoring system based on visible ray:
1. this video frequency monitoring system based on visible ray does not possess night vision monitoring function, because this system is based on gathering visible ray design, can only be operated in intensity of illumination good daytime, even the dusk that illuminance is poor and early morning all cannot work, under night condition, more cannot realize monitoring.
2. this video frequency monitoring system based on visible ray does not possess temp sensing function, in illuminance, do not have well this video frequency monitoring system based on visible ray on daytime of cloud and mist to there is good monitoring performance, often there is the cloud and mist of random drift in forest zone but, the feature of cloud and mist and forest fires is very similar, in the situation that there is no temperature as reference point, this video frequency monitoring system based on visible ray is difficult to be contrasted cloud and mist and forest fires are distinguished by characteristics of image.
3. this video frequency monitoring system based on visible ray does not possess temp sensing function, conventionally only has the real-time fire alarm video image information in forest zone, do not have forest zone to relate to the weather information of humidity, temperature, wind direction, the paper map of only having forest zone, there is no electronic chart, do not have these data cannot make forest zone most important fire alarm ranking score Butut, not only unfavorable to forest fires early warning, also unfavorable to the forest fires work of putting out a fire to save life and property.
4. a little less than the fire alarm point location ability of this video frequency monitoring system based on visible ray, this Surveillance center, the function that does not possess video and map interlock, cannot be in time, effectively fire alarm point is accurately located, also cannot accurately know the geographical conditions of fire alarm point, after fire occurs, can not provide faster, the passage of putting out a fire efficiently.
5. this video frequency monitoring system based on visible ray, owing to only visible ray being processed, monitors sighting distance limited, and guarded region is less, need to arrange a large amount of video cameras based on visible ray in the forest zone of large area region, and lower deployment cost is high.
Summary of the invention
In order to overcome prior art when forest fire protection is monitored, need to need to dispose a large amount of video cameras in forest zone, system cost is high, and these video cameras can only be worked in the good situation of light application ratio, cannot be at nights, even in the lower situation of illumination on daytime, work; Image analysis system in Surveillance center, cannot distinguish the morphological feature of the cloud and mist in forest zone and forest fires, conventionally employing is manually identified and early warning, when occurring, fire also cannot determine in time fire alarm point, the technological deficiency of understanding the geographical conditions of fire alarm point, the invention provides uncooled detector Forest Fire Prevention System.
