Description
Technical field
The present invention relates to laser and drive the bird technical field, in particular to a kind of laser bird-scaring unit.
Background technology
Nineteen ninety to 2010 year; CAAC is about 8.5 hundred million yuan because of bird hits the direct economic loss that aircraft causes; Annual average loss is about 4,000 ten thousand yuan; Wherein direct economic loss in 2010 is about 1.4 hundred million yuan, and this does not comprise because of bird hits the indirect loss that causes, as: airliner delay or cancellation, personnel's life security etc.
The bird method of driving now is divided into the sense of hearing (like coal gas big gun, bird-dispersing car, firecracker ball emitter etc.), vision (driving bird etc. like scarecrow, Colour wind-wheel, terrified eye, laser), sense of smell (like bird repellent, ammoniacal liquor, agricultural chemicals etc.), catches and kills (like shotgun, sticking trammel net etc.), ecological (mowing, desinsection), and the spy bird radar system that is used for birds early warning and detection.
Scarecrow device of the prior art has following shortcoming:
The scarecrow device of the sense of hearing through the threatening birds exists effective range less, to airport environment produce big noise, birds are prone to produce adaptive problem; Through the method for olfactory stimulation birds, because the airport area is very big, the stimulating drug duration is very short, the kind of stimulation birds is limited etc., too many practicality do not possessed; Catch and kill birds and also possibly endanger flight safety, be not the bird mode of driving of green ecological, and night is also inapplicable under the light conditions; Ecological anti-bird with visit the bird radar is that all right ripe, and can only reduce the possibility that birds are entered the airport, do not have the effect of directly driving bird; Traditional vision drives that the bird mode is single, and means are with low content of technology, be used to stimulate the intensity of light of birds lower, so effect is not remarkable.
The present urgent problem of scarecrow device has: solve birds be prone to produce adaptability, solve under the low empty condition of low light drive bird, to solve the big cost of short sphere of action effective time high, lets drive bird and move towards artificial intelligence and drive bird, high-tech drives bird.The vision of birds is the most responsive in all sense organs, and therefore, stimulating the way of birds vision is the most effectively to drive the bird mode.Simultaneously, International Civil Aviation Organization's statistics, 70% bird hits under the light conditions such as occurring in dawn, dusk and night, and 60% bird is hit the low latitude stage in the stage of taking off and landing that occurs in aircraft.
Summary of the invention
