DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar reflected light irradiating apparatus which is installed at an airport where bird strikes are a problem and which repels birds by reflected light of sunlight.

[0002]

2. Description of the Related Art In recent years, birds have become increasingly involved in aircraft, so-called bird strikes. Not only in the aviation industry, but also electric power companies suffering from blackouts (70% of the total) caused by crows nesting in stations, condominiums, warehouses, factories and towers suffering from harm.

[0003] Next, the correspondence of each field will be described.

In the aviation industry, in order to prevent accidents caused by bird strikes, black and white are written on the protrusions (spinners) of the center axis of the engine on ANA, and three-colored eye patterns are written on the wings on Nikko, and red on the wings. A device that emits white or white strobe light was installed, but it became ineffective if the birds got used to it.In addition, the Ministry of Transport and the local government that manages the airport outsourced to local hunting associations etc. to capture birds around the airport They do threatening shots and bombers to get rid of them, but they also have no noticeable effect, saying that "birds get used to it quickly."

For the first time in the nation, a bird damage prevention robot is 1992
This infrared sensor-based bird harm prevention robot was installed in the summer of this year.
It is 1.6 cm, 27.7 cm deep and 32.6 cm high. Originally used for high-voltage power poles, it senses when birds fly nearby by infrared light and emits a sound that combines the sound of seagulls and crows. He also played enka on smoke tubes and sound amplifiers.

In response to other industries, bird strikes include birds, gulls, crows, and pigeons. Other industries suffering from the harm caused by these birds are taking various measures. For example, a sliding bird arrester developed by the Electric Power Center is a countermeasure against crows that build nests on power transmission towers.
When the crow approaches the tower, the sensor reacts and the model crow pops out. This makes use of the crow's territory habits and gives up nesting, making it seem like another crow's territory. In addition, a system has been developed to remove wild birds (starlings and bulbuls) that damage the orchard, analyzing the frequencies of the calls of starlings and bulbuls to detect the most characteristic frequencies. Uses random noise with a large amount of low-frequency components that show a particularly vigilant response to the intimidating noise.It is more efficient than the conventional periodic intimidating noise, and is limited to birds rather than sensors that respond to objects moving with infrared rays. It is effective. A solar cell is used for the power supply of the system.

[0007] There is another example using a biomagnet. A bird harm prevention device that repels birds using a biological magnet that is said to be on the head of birds is in the spotlight. This is based on the theory that birds have biological magnets on their heads, and the magnets read the delicately changing geomagnetism to determine the flight direction, and pigeons and migratory birds return home.

Moreover, these prices range from 85,500 yen to 2
It is for general household use at a relatively low price of 28,800 yen. The installation location is suitable for places where people are relatively dense and need to operate effectively in a relatively small area, such as stations, factories, farms, and warehouses, in addition to homes.

However, in recent airports, under the theme of coexistence of nature and high technology, 40% of artificial islands are being greened, and plans are being made to plant trees around runways, roads, and terminal buildings, and to plant lawns. Yes, but I don't want birds coming in and disturbing the flight.

[0010] Therefore, we are looking for a tree that does not produce berries and has no insects, that is strong against sea breeze, that is not stained with fallen leaves, and that does not require much work. So far, black pine is almost certain.

[0011]

In the techniques cited in these examples, a robot or a permanent magnet installed in a place where it comes in and shows its effectiveness in a relatively narrow range regardless of sound.
It is difficult to cover the area where bird strikes occur, 10km long and 300m high.

As the above countermeasure, the present invention employs a method of stimulating the bird's eyes by light, and a means using laser light is also conceivable. However, since the range of the object is large, a device for emitting laser light becomes large and the like. There is. Therefore, it is an object of the present invention to provide a solar reflected light irradiating device that is relatively small and can be actively controlled by using reflected light of sunlight.

[0013]

According to the present invention, there is provided a solar reflected light irradiating apparatus, comprising: a photosensor for following and detecting the position of the sun; a bird position detecting function for detecting a flight position of a flying bird; Mirror device that collects and irradiates the reflected light of the disk and determines the projection direction of the mirror device that projects the reflected light toward the bird according to the bird position detection function and the command from the photo sensor. And a function.

[0014]

According to the solar reflected light irradiation apparatus of the present invention, the position of the sun is tracked and detected, the flying position of the flying bird is detected, the reflected light of the sun is accumulated and irradiated on the bird, and the position of the bird is detected. The light projection direction of the mirror device that projects reflected light toward the bird is determined according to the function and a command from the photo sensor.

[0015]

Next, an embodiment of the present invention will be described. 1 to 3, reference numeral 4 denotes a photo sensor that detects and tracks the position of a running sun; 12, a bird position detecting function that detects the flight position of a flying bird; A mirror device 1a, which is opened at a substantially central portion of the mirror device 1 and through which light from the sun passes, 13a

Is a first arm rotation axis on which the photo sensor 4 is mounted and the vertical rotation of the photo sensor 4 is freely adjusted by a photo vertical signal from the photo sensor 4, and the state of the photo sensor 4 for recognizing sunlight and the state of the main body. The system consists of two axes that determine the position of the mirror, two axes that determine the position of the mirror, and an axis that rotates the camera (or sensor) that knows the position of the bird.

FIG. 2 is a block diagram of the embodiment. The position of the sun is controlled by a photo sensor 4 having a main body that is actively controlled.
Thus, the position of the bird can be known by rotating the television camera, the angle of the mirror is determined based on the two pieces of information, and the bird is exposed to the reflected light of sunlight. The whole is in the shape of an arm having five joints. As shown in FIG. 3, a through hole 19 through which sunlight passes through the photosensor 4 is provided in the center of the mirror device 1.

A mirror vertical rotation axis 1 and a mirror horizontal rotation axis 2 in FIG. 1 are joints for adjusting the position of the mirror. The sunlight entering through the passage hole 1a in FIG.
The position is adjusted by the second arm rotating shaft 5, but the approximate position is given in advance by data and can be corrected by an optical sensor. Thus, the first arm 6 is directed toward the sun. The photosensor rotation shaft 5 is a joint for rotating the bird detection camera at a high speed, and detects a fast-moving image from the images captured thereby. The mirror horizontal rotation axis 3 and the photo sensor rotation axis 5 are parallel, and the position in the parallel direction is adjusted by the rotation axis 3 and the vertical direction is adjusted by the mirror vertical rotation axis 2.
