Wildlife Invasion Control Device {DEVICE FOR REPELLING ANIMALS}

The present invention relates to a wild animal invasion eradication apparatus, and more particularly, to destroy wild animals that invade farms or orchards and damage crops or orchards so that water is fired toward the wild animals. It relates to a wild animal invasion eradication device.

In general, farms and orchards where various crops or fruit trees grow, and large animals such as wild boars, elk, etc., as well as small animals such as snow hats and pheasants have sprung up to damage crops and fruit trees.

In particular, the wild boar is not a natural enemy at present, the number of population is increasing rapidly, and it is spreading over the mountainous area to the urban area, and the crops are rooted or fruited with a larger size than the damage from eating crops or fruit trees. Damages to crops or fruit trees, which cause secondary damage, such as breaking branches, are often a serious threat to farmers' livelihoods.

Conventionally, active measures such as setting up scarecrows or fences on farms or orchards, installing electric fences along the perimeter, or installing flashing lights at night, etc. Adaptation to countermeasures is ineffective for a moment, so the damage is only increasing without clear measures.

The present invention has been made to solve the above problems, the photographing unit 20 is installed in the farm to shoot the surrounding situation of the farm; An image storage unit 21 connected to the photographing unit 20 to store an image photographed by the photographing unit 20 in units of frames; An image comparator 22 for detecting an invasion point of a wild animal by comparing a frame of a currently photographed image transmitted from the photographing unit 20 with a previous frame stored in the image storing unit 21; A pan / tilt driver 50 mounted on the photographing unit 20 and determining a photographing angle of the photographing unit 20 by changing postures; And a projection angle change which is mounted in the pan / tilt driving unit 50 and is equal to a change in the shooting angle of the photographing unit 20, and is directed toward the corresponding wild animal according to the detection of the wild animal invasion point in the image comparator 22. A projector 60 for projecting water; Characterized in that it comprises a.

Preferably, the projector 60 starts projecting water in a state where the projection angle is adjusted to the center point of the image image captured by the photographing unit 20, and then, by the attitude control of the pan / tilt driving unit 60. The projection angle is changed linearly to the point where the wild animal is detected, characterized in that the linear projection continuously projecting water.

More preferably, the projector 60 starts projecting water in a state where the projection angle is set at the center point of the image image captured by the photographing unit 20 to control the attitude of the pan / tilt driving unit 60. By the U-shaped projection to continuously project water while the projection angle is changed to a curved U-shaped to the point where the wild animal is detected.

More preferably, as the projection angle 60 changes the projection angle to the wildlife detection point by water projection, the photographing unit 20 mounted on the pan / tilt driving unit 50 together with the projector 60 is interlocked. When the center of the photographing angle is changed to the wildlife detection point, and the wild animal is detected again at the photographing angle of the changed photographing unit 20, the projector 60 pans to project water to the escaped position of the detected wild animal again. Tilt drive unit 50 is characterized by a continuous wildlife tracking eradication by the attitude control.

More preferably, the image comparator 22 stops sensing the image while the water is projected.

More preferably, the pan / tilt driving unit 50 is equipped with a speaker 20 that emits sound at the same time as the time of water projection, and the sound emission angle of the speaker 20 when the animal exits the wildlife It is characterized in that the threat sound is emitted toward the wild animal by interlocking with the shooting angle of the projection and the projection angle of the projector (60).

More preferably, liquid naphthalene or garlic oil is added to the water supplied to the projector 60.

Wild animal invasion eradication apparatus according to the present invention is an effect that can be easily eradicated by invading the wild animals by invading the farm or orchard to damage the crops or fruit trees unattended to launch the water toward the wild animals There is.

In addition, by continuously tracking the current location of the wild animals to launch the water has the effect of being able to completely eliminate the wildlife on the farm.

In addition, even if wild animals invade in groups, there is an effect that can be easily combated by U-shaped water projection.

In addition, by continually tracking the current position of the wildlife, it is possible to ensure a clear fight by emitting threat sound with water projection toward the wildlife.

In addition, by adding naphthalene or garlic oil, which the animal does not like, to the water projected toward the wildlife, it is possible to increase the success rate.

Hereinafter, an embodiment according to the present invention will be described with reference to FIGS. 1 and 2.

1 is a block diagram of a wild animal invasion erasing apparatus according to an embodiment of the present invention, Figure 2 is an appearance of a wildlife invasion eradication apparatus according to an embodiment of the present invention.

1 and 2, the wild animal invasion eradication apparatus to which the present invention is applied includes a photographing unit 20, an image storing unit 21, and an image comparing unit 22 for recognizing an invading wild animal. And a projection angle 60 and a pump 61 for projecting water toward the wild animal when the wild animal is recognized, and having the same projection angle as the photographing angle of the photographing unit 20, and the photographing angle of the photographing unit 20. And a pan / tilt driver 50 for equally adjusting the projection angle of the projector 60, and a controller 10 for controlling the above components.

First, the projector 60 has a spout protruding to project water supplied on the pan / tilt driver 50 in the form of a stream of water, and is controlled by the controller 10. When water is supplied from the water, the water is projected as a stream of water. In this case, the pump 61 pumps water supplied from the tap water or the reservoir to the projector 60 through a pipe.

Next, the photographing unit 20 is installed on the pan / tilt driving unit 50 to control the photographing angle by the corresponding pan / tilt driving unit 50 to photograph the current situation of the farm.

Here, the pan / tilt driving unit 50 may operate the pan (left and right posture switching) operation and tilt (under the control of the control unit 10 to change the posture of the projector 60 and the photographing unit 20 installed thereon). Up and down posture switching) to the same operation to the posture switching of the projector 60 and the photographing unit 20. The pan / tilt driving unit 50 is configured to switch the photographing unit 20 repeatedly to repeatedly photograph the predetermined area, for example, the expected invasion path of the wild animal during the routine wildlife detection operation, so that the photographing unit 20 is It is operated to continuously photograph the invasion path of the wildlife.

The image photographed by the photographing unit 20 is stored in the image storage unit 21 in units of frames. At this time, the image storage unit 21 stores the captured image and is deleted by a first-in first-out (FIFO) method.

The image comparison unit 22 compares a frame of an image currently photographed by the photographing unit 20 with a previous frame stored in the image storage unit 21 to recognize the presence of a wild animal. That is, the image comparison unit 22 sets a previous frame stored in the image storage unit 21 as a background image and compares the image frame of the photographing unit 20 which is currently photographed with the corresponding background image to change the value. By detecting the RGB difference value, the moving wild animal can be detected. In this case, the allowable width (RGB difference allowable value) of the change value of the corresponding image comparator 22 may be set to accurately detect only the movement of the wild animal in an outdoor environment with severe environmental changes.

The image comparison unit 22 outputs coordinate information about the image area in which the current change has occurred to the controller 10.

In this case, the photographing angle of the photographing unit 20 and the projection angle of the projector 60 are equally adjusted. That is, since the photographing unit 20 and the projector 60 are installed on the same pan / tilt driver 60, the photographing angle of the photographing unit 20 and the projection angle of the projector 60 are the same. In more detail, the projector 60 may project water in the form of a stem, and the initial projection angle of the water stream of the projector 60 may be adjusted to the center of the image image captured by the photographing unit 20. have.

Therefore, when the image comparison unit 22 transmits left information about the image area where the current change occurs, that is, coordinate information about the area where the current wild animal is detected, to the controller 10, the control unit 10 displays an image. The water is emitted while changing the attitude of the projector 60 whose projection angle is adjusted to the center of the image so that the projection angle is moved to the area where the corresponding wildlife is detected.

That is, the projector 60 starts projecting water in a state where the projection angle is set to the center of the image image and continuously waters the area to which the wildlife is detected by the attitude control of the pan / tilt drive unit 60. Will be projected. This projection function of the projector 60 is referred to as straight projection for convenience in the present invention.

This straight line projection is simply because water is sprayed from the direction the wildlife is approaching to the current location of the wildlife, that is, the water is sprayed from the direction the wildlife is approaching. In addition to allowing them to flee, the water sprayed from the direction they are trying to approach may induce the wildlife to be more frightened, thereby increasing the effectiveness of the wildlife.

In this case, as the projection angle of the projector 60 is changed by the linear projection, the photographing unit 20 installed in the pan / tilt driving unit 50 together with the projector 60 is linked to change the photographing angle. Since the last projection point of the linear projection of the projector 60 is the point where the current wild animal is found, the center of the photographing angle of the photographing unit 20 is automatically moved to the point where the current wild animal is found.

Therefore, when the water escapes and the wild animal escapes, the image comparator 22 immediately finds the location where the wild animal escaped through image comparison, and accordingly, a continuous process of projecting the water to the position where the projector 60 escaped. Through the wild animals will be able to trace and fight to the end.

This will be described in more detail with reference to FIG. 3 as follows.

First, as illustrated in FIG. 3A, when the photographing unit 20 and the projector 60 which are installed in the same pan / tilt driving unit 50 and are switched in posture are operating, the photographed image of the photographing unit 20 is operated. The central zone of and the stream of water projection zone of the projector 60 is an arbitrary point C1.

Here, as shown in FIG. 3B, when a wild animal appears and is found at a specific point C2 of the photographed image, as shown in FIG. 3C, the corresponding pan / tilt driving unit 50 performs a posture change to project the projector 60. ) Directs the stream of water from the point C1 to the point C2, so that the photographed image center region of the photographing unit 20 installed in the same pan / tilt driving unit 50 as shown in FIG. 3D is also C2 at the point C1. Will be moved to the point.

When the watered wild animal escapes and is found again at a specific point C3 of the photographed image as shown in FIG. 3E, the corresponding pan / tilt driving unit 50 also performs a posture shift, as shown in FIG. 3F. As shown in FIG. 3G, the projector 60 projects the water stream straight from the point C2 to the point C3. Accordingly, the center of the shot image of the photographing unit 20 installed in the same pan / tilt driving unit 50 is also illustrated in FIG. 3G. It will be moved from point C2 to point C3.

Therefore, due to the image tracking and continuous water projection of the wild animals found in this way, the wild animals are subjected to water projection until they disappear completely from the shooting angle of the photographing unit 20, that is, completely on the farm. The water streams that follow and track the forests will eventually force the wildlife to leave the farm.

Here, since the water is taken together while the water is projected, the image comparator 22 stops tracking the image while the water is projected, and starts the image tracking after the projection of the water is completed, thereby tracking wild animals due to the water image. Will exclude errors.

As a result, the photographing unit 20, the image storing unit 21, and the image comparing unit 22, which recognizes and tracks a wild animal, need not be expensive image analysis equipment, but simply install a memory and image comparing application. Even if it is, a sufficient configuration is possible.

Here, in the above-described embodiment, the pan / tilt driving unit 50 for shifting the projector 60 and the imaging unit 20 is wild animals at the point C1 currently biased as shown in FIG. Although the projector 60 has been described as performing a linear projection by changing the posture in a linear direction to face the detected point C2, the present invention is not limited thereto, as shown in FIG. U-shaped projection is also possible.

That is, as shown in (b) of FIG. 4, the spot where the wild animal is detected at the point C1 at which the pan / tilt driver 50 for changing the posture of the projector 60 and the photographing unit 20 is currently deflected ( It does not shift in the direction of the shortest straight line toward C2) but shifts to the curved U-shape.

Indeed, wild animals that damage crops often invade large numbers of wild animals in groups rather than invading them individually, so these U-shaped fighters can fit more wild animals into the water and invade them. Favorable for the fight against animals

On the other hand, the speaker 20 is linked to the pan / tilt driver 50, as described above, the photographing unit 20 and the projector 60 is installed in a posture interlocked with the pan / tilt driver 50. Will be installed.

More precisely, the speaker 20 also emits and cuts off the sound at the same time as the projection time of the water from the projector 60 under the control of the controller 10, and the direction of sound emission is also the pan / tilt driver 50. Because it is installed in the area, it is facing the direction in which the wild animal is found at the point where the wild animal is trying to move, which can pose a great threat to sensitive wildlife.

That is, under the control of the controller 10, the sound emission angle of the speaker 30 that generates awkward sound to the animal is the same as the photographing angle of the photographing unit 20 and the projection angle of the projector 60. ) Is installed in the pan / tilt drive unit 50, so that the wildlife is continuously directed toward the animal along with the image tracking and continuous water projection of the found wildlife. Water is projected until it disappears completely from the angle of view, that is, until it disappears completely from the farm, and the acoustic attack eventually leaves the farm.

On the other hand, it is possible to have sufficient effects in combating wild animals by attacking them with water and sound, but by incorporating the animal's dislike scent into the water, it is possible to invade the wild animals such as wild boar herds. It can also be effective to work on.

That is, as shown in FIG. 1, the water (for example, tap water and reservoir) drawn by the pump 61 is mixed in the pump 61 for pumping water provided to the projector 60. ), And a separate chemical tank 62 is installed so that a separate chemical is added to the water drawn by the pump 61.

At this time, the chemical liquid tank 62 is stored in the naphthalene or garlic oil of the liquid disliked by the wild animal is injected into the mixing tank (63).

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited to the drawing.
