Photoelectric target identification bird repeller and bird repelling method

The invention relates to a photoelectric target identification bird repeller and a bird repelling method. The photoelectric target identification bird repeller comprises a machine housing, an optical lens, a photosensitive tube area array, a single chip microcomputer, an ultrasonic transducer, a lighting component and a power supply component, wherein the optical lens is arranged before the photosensitive tube area array; the photosensitive tube area array is connected with the single chip microcomputer; the single chip microcomputer is connected with the ultrasonic transducer and the lighting component; and the power supply component is connected with the photosensitive tube area array and the single chip microcomputer. Compared with the prior art, the photoelectric target identification bird repeller has the following beneficial effects of detecting flying birds entering into a detection zone and effectively repelling the flying birds during the daytime and intermittently excites birds at night so that the birds cannot fall asleep at ease and escape from the periphery of the photoelectric target identification bird repeller. The replaceable optical lens is beneficial to changing the detecting distance and angle on different occasions.

Background

reform and opening up three decades of rapid economic development, rapid development due to high consumption, high pollution makes natural environment has been severely damaged. Deforestation, reclamation orchards, mining coal mining, desertification and urbanization continues to accelerate, so that for the survival of wild birds, living space is reduced, exacerbating some occasions due to birds and humans compete for living space and bring trouble. For example, farmland, orchards, airports and high-voltage transmission lines.

The bird hazard to all farmers have a big problem in recent years, technology pest control has been strengthened greatly increased the farmers' harvests. But to reduce insect and bird damage so the extent of continued deterioration, more and more birds to the fields of fruit as a main source of food. Bird damage seems to have an impact on farmers' income first big harm.

airport bird hazard mainly bird strike event, according to foreign survey, the world's going to happen every year more than ten thousand since the bird strike incidents. With the increase in this number is the route annually, bird strike incident has seriously affected the flight safety of the aviation industry. Once the bird strike accidents, losses tend to be quite large.

With the reduction of the forest, high-voltage wire tower become some of the best nesting place for birds of prey. Windy rains nests it may cause a short circuit between the high-pressure line jump, and once jumped off between the accident, the impact on production and life of not a few of the digital economy that can be explained.

How effective prevention and treatment of human bird damage as a troubled international problems. The traditional scarecrow bird has been eliminated, put bird netting will hurt the birds. A bird repellent spray is a more effective way, bird repellents would cause environmental pollution. Sonic bird because of its environmental pollution, does not hurt the birds, it was gradually extended. Existing acoustic bird, the bird can be divided into audio, high-decibel sound of explosions and ultrasonic bird bird.

audio bird is by playing bird predators or birds chirping whine sound so the birds fear and flee. However, this bird has a great way of regional restrictions, use of effects in different regions hate big difference. Capital International Airport as a "bird king" device, the sound of bird approach works well in the United States, can play over the airport in the capital Shique useless. Because the chip storage are some foreign sound of birds, the birds can not understand China, "foreign language." High-decibel explosion bird, is to use an electronic gun gas gun or produce more than 180 db sound of explosions to scare off birds, but over time the birds can easily adapt.

The ultrasonic bird, is by playing the ultrasonic stimulation of the nervous system of birds to physiological disorders and fled. Since the ultrasonic frequency is higher than the range of the human ear can hear, and thus will not affect human life. Reduced by the constantly changing sound frequencies limiting the impact time, and there is no geographical restriction effect, suitable for mass application. Existing domestic ultrasonic bird control are mainly timed work, regular work undoubtedly greatly accelerate the adaptation of birds ultrasonic speed. Using detection methods can eliminate the impact of this, the existing bird photoelectric detection is the use of pyroelectric infrared detection birds, easily affected by ambient temperature, and the detection distance is short, easy due to environmental factors bird control malfunction.

The main object of the present invention to overcome the prior art photoelectric detection bird control bird ineffective shortcomings, there is provided a photoelectric target identification bird and bird method using an optical lens imaging technology, greatly improve the detection distance and accuracy.

The present invention adopts the following technical solution:

A photoelectric target recognition bird control, including housing, optics, photodiode array surface, single-chip, ultrasonic transducers, lighting components and power components, the optical lens is disposed on the light-sensitive surface sounding tube, the photodiode array surface connecting the microcontroller, the microcontroller is connected to the ultrasonic transducer and the lighting assembly, the power supply module is connected to the photodiode area array and the microcontroller. Ultrasonic transducer signals generated by the microcontroller converts ultrasound.

The optical lens from the tube, diaphragm, panels and lenses. Aperture is used to control exposure to flux photodiode array on the surface. Optical lens focal length of 10~100mm, adjust the aperture so that the illumination photodiode array on said surface of 20~ 401ux (outdoor illumination 1000~15001ux case).

The optical lens to the image plane and the surface of the photodiode array in the same plane.

surface of the photodiode array by the twenty-two series photodiodes arranged in reverse chip components.
