Description
Technical field
The present invention relates to technical fields, more particularly to a kind of forest fire alarm system based on contact switch.
Background technique
Forest fire not only burns to death, forest of burning, directly reduction area of woods, and seriously destroys forest structure and forest
Environment leads to forest ecosystem disequilibrium, forest biomass decline, and productivity weakens, and beneficial beast beneficial bird is reduced, or even is caused
People and animals' injures and deaths whole world is every year since forest fire causes over thousands of people dead.The factory in forest zone, house, bridge, railway, power transmission line
Road, herding, grain etc. are frequently subjected to the threat of forest fire.Such as: Daxing'an Mountainrange extra big forest fires burn three within 1987
85 ten thousand stere of timber (is burnt) in forestry bureau location, nine forest farms site, four and half timber depots, 67, bridge, railway 9.2km, defeated
Electric line 284km, 6.4 ten thousand square metres of house, 3,250,000 kg of grain, various equipment 2488.Lose very heavy, direct economy
Lose 4.2 hundred million yuans.So the position that forecast forest fire promptly and accurately occurs is just very crucial and necessary.
Current forest fire monitoring system monitoring means is single, and monitoring parameters are single, so that the prediction of fire has one
Fixed limitation can not give a warning after the completion of predicting fire and after fire generation to prompt related personnel to carry out fire in time
Calamity fighting work is unfavorable for putting out in time for fire so that the information of fire has certain retardance.
Large-scale forest farm mostly passes through the generation of the monitoring means monitoring fire such as satellite monitoring, aviation monitoring, such monitoring hand
Section can accurately be monitored point of origin and the intensity of a fire, but the monitor mode equipment cost is high, is not suitable for small-sized forest farm.
