Problems solved by technology

[0005] The bird repelling equipment that scares the bird's sense of hearing has a small effective range, produces loud noises to the airport environment, and the birds are prone to adaptability; the method of stimulating birds through the sense of smell, because the airport area is huge, and the stimulating drugs last The time is very short, the species of stimulating birds are limited, etc., so it is not very practical; killing birds may also endanger flight safety, it is not a green and ecological bird repelling method, and it is not applicable under low light conditions at night; ecological bird prevention and Bird detection radar is still immature, and can only reduce the possibility of birds entering the airport, and does not have the effect of direct bird repelling; the traditional visual bird repelling method is single, the means are low in technical content, and the intensity of light used to stimulate birds low, so the effect is not significant
[0006] The problems that bird repellent equipment needs to solve urgently are: to solve the adaptability of birds, to solve the problem of bird repelling under low light and low altitude conditions, to solve the problem of short effective time, large range of action and high cost, so as to make bird repellent move toward artificial intelligence and high-tech bird repellent

Embodiment 1

[0032] Embodiment 1 A green laser beam with a specification of 532nm / 500mw is used. The diameter of the laser scanning beam is kept at 152mm both near and far, and the laser density is uniform. After the laser scanning beam is emitted from the transparent window 21, the angle is always towards the horizontal plane below. Such a laser-scanning beam looks like a big green stick. Birds can't distinguish the reality of this big green stick. Therefore, when the laser scanning beam scans the area where the birds are, the birds think that someone is holding a huge green stick and waving it on the runway and grass. The only choice for birds Just run away. Birds are as frightened by a strafing laser scanning beam as they are by an oncoming car.

[0033]According to statistics, bird strikes that occur under low-light conditions account for 70% of the total number of bird strike accidents, and bird strikes that occur at low altitudes, especially during takeoff and landing, account for ...

Abstract

The invention provides a laser bird dispeller which comprises a box body (10), a rotary tower (20), a laser transmitting unit and a controller, wherein the rotary tower (20) is pivotally arranged on the box body (10) and provided with a transparent window (21); the laser transmitting unit is arranged in the box body (10) and comprises a laser source (61) and an optical conversion unit; the laser source (61) emits a laser beam which is processed by the optical conversion unit to obtain a laser scanning beam, and then the laser scanning beam is emitted out of the transparent window (21) for scanning; and the controller is used for controlling the laser source. The laser bird dispeller provided by the invention fills in the blank of bird dispelling means under low-light and low-altitude conditions, and can effectively dispel birds standing on the runway and / or grassland. Meanwhile, the laser scanning beam scans below the horizontal plane and does not obstruct the sight of pilots, thereby guaranteeing the flying safety.

Description

technical field [0001] The invention relates to the technical field of laser bird repellent, in particular to a laser bird repellent. Background technique [0002] From 1990 to 2010, the direct economic loss caused by bird strikes in China's civil aviation was about 850 million yuan, and the average annual loss was about 40 million yuan, of which the direct economic loss in 2010 was about 140 million yuan. Indirect losses caused by attacks, such as flight delays or cancellations, personnel safety, etc. [0003] The current bird repelling methods are divided into hearing (such as gas cannons, bird repelling vehicles, firecracker launchers, etc.), vision (such as scarecrows, colorful wind wheels, horror eyes, laser bird repelling, etc.), smell (such as bird repellents, ammonia water, etc.) , pesticides, etc.), hunting (such as shotguns, sticky bird nets, etc.), ecology (mowing, insecticide), and bird detection radar systems for early warning and detection of birds.
