FIG. 6 shows the overall schematic configuration of the present invention. Reference numeral 6 denotes a battery that stores electricity generated from the solar panel 1. The solar panel 1 and the battery 6 are connected via a charging controller 7. .
Furthermore, the AI computer 8 and the control board 9 are connected as appropriate, and the control board 9, the camera 4 and the speaker 5 are provided.

An enclosing frame drawn with a two-dot chain line indicates the housing 2 . That is, part of the camera 4 (lens) and part of the speaker 5 are exposed on one side of the surrounding wall of the housing 2 , but most of them are built in the housing 2 .
The battery 6 , charge controller 7 , AI computer 8 and control board 9 are housed in the internal space of the housing 2 .

A rectangular parallelepiped housing 2 as illustrated in FIG. 1 and a solar panel 1 protruding upward are used as an integrated unit at places where birds are expected to fly, such as temples, stations, parks, fields, and buildings. , is installed. Moreover, as can be seen from FIG. 1, the housing 2 can stand on its own integrally with the solar panel 1, and can be installed in various places without requiring electricity from the outside.
Further, FIG. 2 exemplifies a power transmission tower 10, and a plurality of bird repelling devices E are installed in each part. In particular, install it at a place where crows may fly to build a nest (place where birds are expected to come).

3 and 4 exemplify another embodiment of a bird repelling device E attached to the structural frame member 11 of the steel tower 10 in FIG.
As shown in FIGS. 3 and 4, a mounting pedestal 12 is fixed to the frame member 11, and the pedestal ₁₂ is rotated about a _single vertical axis L12 as shown by an arrow M1. , the housing 2 is mounted on the pedestal 12 via a fixation mechanism G (see FIG. 5(A)) whose direction can be changed and which can be freely fixed.
In addition, in FIGS. 2, 3, and 4, it can be said that the location where birds are predicted to come flying is a part of the power transmission tower 10. FIG. Moreover, it is a site where crows easily nest.

3 and 4 are perspective views seen from substantially the same position. The mounting base 12 includes a mounting plate 12A placed on the component frame member 11, and a mounting plate 12A suspended from the mounting plate 12A. A leg piece 12B provided and another leg piece 12C that can be freely fastened to the leg piece 12B with a bolt and nut connection 12E are provided.
The leg pieces 12B and 12C are tightened by the bolt-nut connection 12E so as to hold the frame member 11, and are firmly fixed to the frame member 11. As shown in FIG.

Then, one embodiment of the fixing mechanism G will be described with reference to FIG. 5(A). A deformed hole 13 having a polygonal shape, a spline shape, or the like is provided through the central region of the bottom wall plate 2B of the housing 2, and the deformed hole is projected from the upper surface of the mounting plate 12A of the mounting pedestal 12. A short shaft portion 14 having a polygonal shape or a spline shape corresponding to the shape of 13 is integrally provided.
The fixing mechanism G is composed of the deformed hole portion 13 and the short shaft portion 14, and when the housing 2 approaches the mounting plate 12A as indicated by the arrow K, the housing ₂ is moved toward the mounting plate 12A as indicated by the arrow M1. can be rotated to set the front wall 20 (containing camera 4 and speaker 5) of housing 2 to the desired (horizontal) orientation.

In this way, it is possible to make settings so that birds such as crows 30, etc., are directed toward predicted flying bird locations, as shown in FIG.
3 and 4, different directions (in the horizontal plane) can thus be set in which the front wall 20 with the camera 4 and the loudspeaker 5 is facing.

Then, the solar panel 1 is attached to the housing ₂ via a fixing mechanism G2 that can be fixed to the housing ₂ in a predetermined rotational direction around the vertical axis L2. is fixed in the direction that receives the sun's rays most efficiently.
An embodiment of the fixing mechanism G2 for the solar panel ₁ will be described with reference to FIGS. 5(B) and 4. FIG. As shown in FIG. 4, the solar panel 1 has a pair of left and right triangular support frames 15, 15, and a support plate 16 to which the bottoms of the left and right support frames 15, 15 are fixed. As shown in FIG. 5(B), the support plate 16 has a hole 17 having a polygonal shape, a spline shape, or other irregular shape in its central region. Further, a short shaft portion 18 having a polygonal shape, a spline shape, or the like corresponding to the shape of the deformed hole portion 17 is integrally provided as a projecting shape from the upper surface of the ceiling wall plate 2C of the housing 2 .

_The fixing mechanism G2 is composed of the deformed hole portion 17 and the short shaft portion 18, and moves the support plate 16 of the solar panel 1 toward the ceiling wall plate 2C of the housing ₂ as indicated by the arrow K2. At this time, the solar panel 1 and the support plate 16 are rotated as indicated by the arrow _M2 to set the light-receiving surface of the solar panel 1 in a desired direction.
As described above, the housing ₂ itself is changed by the fixing mechanism G so that it faces the point where birds are predicted to come flying, as indicated by the arrow M1 in FIG. The solar panel 1 can be changed to the direction of the arrow _M2 in _FIG . 5(B) by another fixing mechanism G2 to be set in the direction in which the sunlight is most likely to be received.

Next, in FIGS. 5(C) and ₄ , a fixing mechanism G2 which can rotate the solar panel ₁ around a vertical single axis L2 (like an arrow _M2 ) and fix it in a predetermined direction. shows another embodiment of In the embodiment shown in FIG. 5(C), the support plate 16 of the solar panel 1 can be rotated around a similar vertical _single axis L2 as indicated by the arrow _M2 by means of the pivot shaft 19. After rotating it to the desired direction, the bolts 21 are passed through the through holes 16A of the support plate 16 and screwed into the screw holes 22 of the ceiling wall plate 2C of the housing 2. FIG.

In this way, the fixing mechanism G2 is formed in the ceiling wall plate _2C of the housing 2 on a large-diameter circular line centered on the axis of the short pivot shaft 19. 22 and at least one through-hole 16A, preferably two to four through-holes 16A formed on the same circular line of large diameter in the support plate 16, and through-holes 16A. It is composed of a bolt 21 screwed into a screw hole 22 .

The bird repellent device according to the present invention comprises detection means for analyzing the image taken by the camera 4 and detecting only the target birds--for example, the crow 30--.
Moreover, the AI computer 8 (see FIG. 6) analyzes the image captured by the camera 4, and only when the crow 30 is detected, the avoidance sound is transmitted from the speaker 5. FIG. As a result, both effects of power saving and continuation of the repelling effect are exhibited.

Further, in the present invention, the detection of birds by the detection means is intermittently performed at predetermined time intervals (rather than continuously). That is, the above detection is performed at the minimum required interval to save power.

_FIG . 7 shows _an image of the crow 30 detected by the camera. The AI computer 8 of FIG. Only 30 characteristic heads H ₁ and H ₂ can be detected by AI deep learning. Moreover, the crow 30 at the lower right position in FIG. 7 is partially hidden by the structural frame member 11 of the steel tower 10, but can be detected by the AI computer 8 (see FIG. 6).

Next, by using a digital zoom method as shown in FIG. 8, it is possible to detect birds in the distance (which look small) as crows. That is, the camera image 25 in which the crow looks small is taken as No. 1, No. 2, No. 3, No. Divide into four like 4. The number divided into four. 1 to No. 4, digital zoom processing D is performed on each image. Enlargement improves the detection rate.

However, No. 1 to No. In each of the four divided images such as No. 4, concretely No. 1 and No. In 2, the whole crow is not shown. In such a case, the cuts of the four divisions are overlapped so that No. 5 to No. Cut as shown at 9 and no. 5 to No. Specifically, if the digital zoom processing D is performed on each image of No. 9, 5 and No. It can be seen that at 7 a magnified global image of the crow is obtained.

In this way, the detection rate can be improved by dividing the camera image 25 shown in FIG. 8 into nine and digitally zooming.
In other words, the (camera) image 25 captured by the camera 4 is divided into a plurality of pieces, and each divided image No. 1 to No. 9 can be digitally zoomed to create an enlarged image of the entire distant bird, and the detection means can identify whether it is the target bird (crow 30) or not.

Next, Fig. 9 shows that the detection rate changes depending on the distance from the camera to the crow, which is short, medium, or long, when AI analysis is used to detect a crow from an image of a bird captured by a camera. (A) is an explanatory diagram of the division of the distance from the camera to the crow, (B) is the detection rate by AI analysis for each short, medium, and long distance of (A) decreases.
FIG. 9B shows that the detection rate is 64.7% to 92.1%, and there are frames in which crows cannot be detected.

In the present invention, a large number of frame detection processes of 4 frames or more and 12 frames or less are performed in one second. Therefore, as shown in FIG. 10, assuming that 8 frames are detected in one second, the blurred crow figure indicates non-detected frames, and no repelling sound is produced.
However, since the blackened crow figure always exists, it is possible to emit the repelling sound V5 (for example) _five times in one second, and there is no practical problem.

Furthermore, it is desirable that the repelling sound V5 from the speaker ₅ is a high-speed pulse with a rapid rising edge. That is, as explained in FIG. 10, it can match multiple transmissions per second, has a high startle effect and has a great ability to control birds (crows), and generates high-speed pulses with a microcomputer program. There is also the advantage that the frequencies are frequently changed to prevent habituation to birds (crows).

In the embodiments described with reference to FIGS. 1, 2 to 4, 10, etc., the configuration is such that the speaker 5 generates the "repellent sound" for birds. Another embodiment will now be described. It is also desirable (not shown) to use a laser beam illuminator to generate a "repellent light" for birds. This laser beam irradiator may be attached to a part of the housing 2 or to a part (such as a frame) of the solar panel 1 (not shown).
It should be noted that both the camera 4 and the laser beam irradiator can be provided so as to generate both a repelling sound and a repelling light for birds.

Next, the operation of the bird repellent device according to the present invention is illustrated in the flow chart of FIG.
When the power is turned on, a detection operation 31 is performed for a short period of time T1, and if _a crow is detected 32, a repelling sound 33 is generated.

The short second T ₁ is, for example, 8 to 15 seconds. In FIG. 11, it is set to 10 seconds.
However, if no crow is detected for the short time period T1, the process proceeds to sleep 34 for _a certain period of time. It is desirable that this fixed time T ₂ is about 2 minutes to 4 minutes. In FIG. 11, T ₂ =3 min.
Next, it discriminates 35 whether it is "daytime" or "nighttime". If it is daytime, return to the detection operation 31 and repeat the above operations.

As described above, the detection (detection) of birds (crows) by the detection means is performed intermittently for a short period of time T1 with the sleep 34 intervening for _a certain period of _time T2. In other words, it can be performed intermittently at predetermined time intervals T ₁ +T ₂ and also contribute to power saving. Since the sleep time T2 is as short as, for example, ₃ minutes, even if birds (crows) are present at the predicted flying location, no actual damage will occur.
In addition, as shown in FIG. 11, in the determination 35 of whether it is daytime or nighttime, in the case of nighttime, shutdown 36 is performed to further reduce power consumption.

By the way, the number and time of detection of birds (crows) by the detection means are stored, for example, in a memory (not shown) attached to the control board 9 in FIG.
There is an advantage that it is possible to determine whether to remove (relocate) the bird repellent device E installed at a predetermined bird flying prediction location or to continue to install it based on the data stored in the memory. .

As described in detail above, the present invention comprises a solar panel 1, a battery 6 for storing electricity generated from the solar panel 1, a speaker 5 for generating a repelling sound against birds using the electricity from the battery 6, and a bird. and a detection means for analyzing the image taken by the camera 4 and detecting the bird as a target, and are configured to be installed at the location where the bird is predicted to come flying, It can be installed and used even in places where electricity for power supply is difficult to obtain. Also, it is certainly possible to detect and repel target (harming) birds only.

Also, the present invention comprises a solar panel 1, a battery 6 for storing electricity generated from the solar panel 1, a laser beam irradiator for generating repelling light against birds using the electricity from the battery 6, and a bird photographing device. It is equipped with a camera 4 and detection means for analyzing the image taken by the camera 4 and detecting birds as targets, and is configured to be installed at a location where birds are predicted to come flying. It can be installed and used even in places where it is difficult to obtain. Also, it is certainly possible to detect and repel target (harming) birds only.

In addition, the present invention attaches the solar panel 1 to the housing 2 in an upwardly protruding shape, houses the battery 6 inside the housing 2, and stores a part of the surrounding wall 2A of the housing 2. Since the speaker 5 and the camera 4 are arranged in the body, the self-supporting type can be securely and easily installed in any place (place). In addition, the solar panel 1 can have a structure that does not easily fall down due to wind or the like, and can be made compact.

In addition, the solar panel 1 is attached to the housing 2 in an upward protruding shape, the battery 6 is housed inside the housing 2, and a part of the housing 2 or a part of the solar panel 1 Since the laser beam irradiator is attached and the camera 4 is arranged on a part of the surrounding wall 2A of the housing 2, it can be securely and easily installed in any place (place) as a self-supporting type. can. In addition, the solar panel 1 can have a structure that does not easily fall down due to wind or the like, and can be made compact.

In addition, it has a mounting pedestal 12 fixed to the structural frame member 11 of the steel tower 10, and through a fixing mechanism G that can be fixed to the pedestal ₁₂ in a predetermined rotational direction around the vertical single axis L12. Since the housing 2 is mounted on the pedestal 12, it can be easily, quickly and firmly attached to the structural frame member 11 of the steel tower 10. As shown in FIG. Moreover, the direction of the camera 4 and the speaker 5 attached to a part of the surrounding wall 2A of the housing 2 can be easily rotated and fixed in a direction in which birds can be easily monitored and detected. In particular, the housing 2 can be fixed safely and reliably to the structural frame member 11 located at an extremely high place of the steel tower 10, and the directions of the camera 4 and the speaker 5 provided on the housing 2 can be adjusted safely. and can be done quickly.

Further, according to the present invention, the analysis of the image taken by the camera 4 is performed by the AI computer 8, and the repelling sound V5 is transmitted from the speaker ₅ only when birds are detected. , the accuracy of detecting only crows (for example) as targets from the image taken by the camera ₄ is high, and the repelling sound V5 is not emitted wastefully. Thereby, power saving can be achieved. Moreover, regardless of whether birds are detected or not, compared to the case where the repelling sound _V5 is continuously emitted repeatedly at predetermined short intervals, the power consumption can be significantly reduced, and the size of the solar panel 1 can be reduced. It also contributes to the improvement of In addition, it is possible to prevent the repellent effect from deteriorating due to the birds becoming accustomed to it (repellent effect is continuously exhibited).

Also, the operation for detecting birds by the detection means is an interval operation through sleep for a certain period of _time T2, so that the detection of objects (birds) can be kept to a minimum and power can be saved. can make a big contribution. For example, in the embodiment shown in FIG. 11, the activation time T1 is ₁₀ seconds for a sufficiently long sleep of T2 ₌ 3 minutes = ₁₈₀ seconds and T1:T2 ₌ 10 seconds: 180 seconds = 1:18 . becomes. It can be seen that the operation time T1 is _{only 1/18} of the constant sleep time T2, which greatly contributes to power saving.

In addition, since a memory is provided for storing the number of times and time of detection of birds by the detection means, it is possible to determine after a predetermined period whether or not the location where the bird repelling device is installed is appropriate for predicting the arrival of birds. It is possible to accurately determine whether the bird repellent device should be continuously installed at that place (location) or removed (whether or not the installation should be continued).

In addition, the above image taken by the camera 4 is divided into a plurality of pieces, and each divided image is subjected to digital zoom processing D to create an overall enlarged image of a bird at a long distance. Since it is constructed so as to distinguish between the two, the detection area can be expanded and the detection rate can be improved. It is also possible to reliably identify whether the object is a bird or not.

In addition, since the above-mentioned bird flying prediction point is a high part of the power transmission tower 10, if a crow nests with a nesting material at a high part of the power transmission tower 10 shown in FIG. occurs. In addition, it is estimated that more than 170,000 birds are removed every year due to nesting damage caused by crows. The time and expense involved in removing nests by nest removal workers is enormous. With the device according to the present invention, it is possible to prevent crows and the like from flying and nesting, thereby reducing the above-described nest removal work and saving the removal cost.

In addition, since the repelling sound V5 from the speaker ₅ is a high-speed pulse with a rapid rise in sound, it has a high startling effect on birds and exerts a great control effect. In addition, if the high-speed pulse of different frequency is used each time, the bird will not become accustomed to it, and the pest control effect will be exhibited over a long period of time.
