Description

Bird fighting system

TECHNICAL FIELD The present invention relates to a pest killing technology, and more particularly, to an algae fighting system.

Airfields, farmhouses, and aquaculture farms use a variety of methods to combat harmful organisms such as algae, and auditory, olfactory, visual, and tactile methods have been studied.

Visual elimination methods using natural models or glittering visual stimulants, or olfactory methods using bird repellents, have significant drawbacks, and tactile methods using insect screens and nets have high utilization costs due to high facility installation and maintenance costs. . Thus, an auditory method with a somewhat slower learning effect is mainly used for bird control.

Acoustic algae exterminating device is an apparatus for extinguishing algae in a desired space by using an acoustic signal and is classified into a binge, gunfire, bird evasion / removal / control sound, and an ultrasonic wave. It is mainly adopted because the installation and maintenance cost per unit area is cheaper than the visual eradication device, and can be summarized as shown in [Table 1].

Table 1

Classification		Explanation	Sound pressure level
explosion		Induce algae spawning using a binge	130dB minimum
Gunshot		Induces bird spawning with dread bullets, shotguns, and shotguns	125 dB minimum
Avian	Synthesized sound	Induces bird spawning using voice recording and radio	110 dB minimum
Avian	Natural sound	Records the algae of the bird, causing bird spawning	110 dB minimum
Bird control	Resonance	Causes pain by using sounds that stimulate the bird's auditory organs	130dB minimum
Bird control	Electronic sound	Induce spawning using sound that threatens the bird	130dB minimum
Bird control	language	Record and use the sound of birds that do not approach using the language of the bird	110dB minimum
	Pain	Record sounds of pain on the birds to keep them from being accessible	110 dB minimum
	Bunch	Record the chaotic situation of the flock of birds to keep them out of reach	110 dB minimum
ultrasonic wave		Considering the bird's audible frequency band, humans induce spawning using inaudible ultrasonic sound	120 dB minimum

Acoustic algae control device (explosive device) can be used to set the output interval (40 seconds to 30 minutes) by using the explosion sound control device, control the volume up to 130dB, and adjust the volume up to 100dB by using the volume control. Can be. There is no risk of explosion in the case of solar bomber can be used semi-permanently. However, the explosives appear to have a wide range of effects at the beginning of the installation, but only a temporary effect appears only with loud and repetitive sounds, and there is a problem that the effects are greatly reduced as time passes by learning.

Acoustic bird control devices using guns are mainly used to prevent bird collisions with aircraft at airports and the like. It can be used as a grenade that fires more than 125dB of fire, or shotguns that fly tens of meters and spread rubber debris around a flock of birds. In the early stages of use, you can get a great effect with a single shot of a dread shot, but if you learn that birds do not have direct damage, they have a disadvantage that they do not fly away again. In order to eliminate this learning effect, there is a problem in that, in addition to a shotgun and shotgun, a shotgun must be used to periodically kill birds.

Other acoustic bird killers include evasion sounds (warning sounds, stress sounds, and natural sounds), bird-tolerant sounds (resonant sounds, electronic sounds), bird control sounds (language, pain sounds, herds) There is a system that embeds the sound into the memory chip and radiates it through the speaker so that harmful birds escape from the area. In addition to the ability to select a variety of sounds, the system allows for volume control, sound emission intervals, and arbitrary or continuous adjustment of the sound, making it easier for birds to become familiar with specific sound patterns. However, most products on the market today have a narrow range of applications due to their low acoustic output. In addition, since the foreign products occupy most of the device using the algae control sound, there is a problem that the effect is insignificant because there is little connection with native Korean birds.

On the other hand, the ultrasonic algae extinguishing device is a device that allows the algae to feel the threat and leave the area by radiating a specific threatening ultrasonic frequency signal in consideration of the audible frequency band of the harmful algae. The biggest advantage is that it does not cause noise in humans because it uses ultrasonic waves to escape harmful birds. However, when used for a long time, the resistance to the ultrasound is generated and the effect cannot be guaranteed. In addition, the ultrasonic wave can be used only for near or indoor use because the attenuation by air is severe. Therefore, expensive large-power ultrasonic devices are required to be applied to a wide range of outdoor spaces such as fruit farms and farms.

Another acoustic algae killing device is a long range acoustic algae killing device. The device uses a directional sonic transmitter that concentrates the acoustic signal into a specific area, radiating high-powered sound close to 150 dB. It can be linked with surveillance cameras to determine the type of birds. Recently, unmanned bird control robots combined with unmanned robot technology have been developed. A directional sound wave transmitter is a device that radiates high-power sound to a specific area, but the sound is radiated over a large area, causing damage to ambient noise. In addition, as the sound is radiated from a long distance, the threat is attenuated and the learning effect of the bird is increased. In addition, there is a problem that is difficult to popularize because it is produced at a high price.

On the other hand, the unmanned bird control robot is a device that combines a semi-autonomous mobile robot and a long-range acoustic bird extinguishing device, the mobile robot to close the bird near the bird under the control of the control room radiates a laser beam or the sound of extermination to combat the bird. Since the mobile robot emits a repellent sound suitable for the characteristics of the recognized bird in close proximity to the bird, there is an advantage of reducing the learning effect of the bird, but it is expensive and requires a lot of operating costs. In addition, the learning effect can be slowed down, but not the bird's learning effect on the robot. In addition, there is a problem that causes a large amount of ambient noise because it uses a high-power sound reproduction device.

The present invention has a technical problem to provide a bird fighting system that can suppress the learning effect of algae.

Another technical problem of the present invention is to provide an algae control system capable of minimizing noise and combating harmful organisms in the surroundings.

According to an aspect of the present invention, there is provided a system for combating birds, comprising: a memory in which a plurality of radiation patterns and at least one combat sound are stored; A repellent sound output unit disposed at an outline of the combat plan region divided into unit cells having a specified width and a boundary between the unit cells, and including a plurality of speakers each having an identifier; A speaker manager to manage the plurality of speakers; An extermination command processor for generating an extermination command and reporting it to the controller as the bird appears; A pattern selection unit that selects any one of various radiation sound patterns stored in the memory under the control of the controller, as the erasure command is generated; And a control unit configured to sequentially drive a speaker to output a combat sound according to the selected radiation pattern with reference to the speaker manager, as the radiation pattern is selected.

According to the present invention, in order to effectively use a bird's threat to an object that is approaching, it is possible to maximize a bird's threat by radiating a moving sound approaching the bird, and output a sound in various patterns to improve the learning effect of the bird. Can be suppressed.

In addition, since the sound is emitted toward the bird to combat the impact of the ambient noise can be minimized.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention in more detail.

1 is a block diagram of a bird control system according to an embodiment of the present invention.

Referring to FIG. 1, the bird control system 10 according to an embodiment of the present invention includes a controller 110, a memory 120, an operator interface 130, a speaker manager 140, a combat command processor 150, The pattern selector 160 and the combat sound output unit 170 are included.

The controller 110 controls the overall operation of the bird control system 10, the memory 120 stores various application programs, control data, etc. necessary for the operation of the bird control system 10, and further various radiation patterns And various combat sounds.

The operator interface 130 is configured to allow the operator to access the bird elimination system 10, and output an operation state of the bird elimination system 10, and the like.

The speaker manager 140 manages the plurality of speakers 174 constituting the combat sound output unit 170. An identifier may be assigned to each of the plurality of speakers 174, and the speaker manager 140 manages an operation state, an arrangement position, and the like of each speaker according to the identifier.

The elimination command processing unit 150 generates a elimination command and informs the control unit 110. The extermination command may be directly input by the operator through the operator interface 130 or may be generated directly by the extermination command processor 150 with reference to the recognition result of the surveillance camera 180. In addition, the combat command processor 150 may determine whether or not the combat is successful in association with the monitoring camera 180, and regenerate the combat command when the combat command is not successful.

As the pattern selection unit 160 generates an eradication command by the erasure command processing unit 150, any one of various radioactive sound patterns stored in the memory 120 and various eradication sounds may be controlled by the control unit 110. Select.

In addition, the repellent sound output unit 170 outputs the repellent sound selected according to the radiation pattern selected by the pattern selector 160. The combat sound output unit 170 includes an amplifier 172 and a plurality of speakers 174. In particular, the speaker 174 is installed by wire or wirelessly in the area to be eradicated, and each has a unique identifier. When the speaker 174 is wired, the amplifier 172 may be configured as a multichannel amplifier. On the other hand, when the speaker 174 is installed wirelessly, each speaker 174 may be configured to incorporate an amplifier, each speaker and the control unit 110 is commanded by a near field communication method such as RFID or Zigbee method And control signals can be transmitted and received.

As described above, in the present invention, the speaker 174 is installed in the eradication area, and the erasure area may be divided into unit cells having a predetermined width.

2 to 4 is a layout view of the speaker according to an embodiment of the present invention.

First, FIG. 2 is a layout view 20 when the eradication plan area 210 is divided into a plurality of unit cells 220, and speakers 230-1 to 230-4 having a predetermined interval are installed in each unit cell 220. ).

Each of the speakers 230-1 to 230-4 may be installed such that an output direction thereof faces a center point of the cell 220, and may be configured using a directional speaker.

The unit cell 220 may be divided into, for example, a quadrangle. In this case, the speakers 230-1 to 230-4 may be installed at each vertex of each cell.

3 illustrates a case in which the speaker layout diagram 30 divides the eradication plan area 310 into a plurality of unit cells 320, and the speakers 330-1 to 330-9 are installed at the boundary points of the unit cells 320. Indicates.

In the present embodiment, each speaker 330-1 to 330-9 may be an omnidirectional speaker, but is not limited thereto. In particular, the speaker 330-1, 330-2, 330-3, 330-4, 330-6, 330-7, 330-8, and 330-9 arranged at the outline of the eradication plan area 410 has an output direction. It may be a directional speaker facing the center of the area to be combated.

4 is an aerial radial speaker layout 40. As in FIGS. 2 and 3, the eradication plan area 410 is divided into a plurality of unit cells 420. In addition, air radial speakers 430-1 to 430-9 are provided at the boundary points of the unit cells 420.

This embodiment has a feature that can emit a kill sound toward birds in flight in the air.

In the present invention, as shown in FIGS. 2 to 4, the

eradication plan regions

310, 310, and 410 are divided into a plurality of

unit cells

220, 320, and 420, and a plurality of speakers are provided near the boundary of each unit cell. When the tidal wave appears, the elimination command processor 150 generates an elimination command, and accordingly, the pattern selector 160 selects a radiation pattern and an elimination sound.

The selected eradication sound is radiated to the eradication plan area through the plurality of speakers sequentially driven according to the selected radiation pattern.

This process is described below with reference to FIGS. 5 and 6.

5 is a flow chart for explaining a bird fighting method according to an embodiment of the present invention.

As the algae appear in the eradication scheduled area, the eradication command processing unit 150 generates an eradication command (S101).

Accordingly, the controller 110 operates the pattern selector 160, and the pattern selector 160 selects the radiation pattern with reference to the memory 120 (S103). In this case, the pattern selector 160 may select any one of various eradication sounds stored in the memory 120 in addition to the radiation pattern.

As the radiation pattern is selected, the controller 110 sequentially drives the speaker 174 that will output the radiation pattern with reference to the speaker manager 140 to emit a combat sound (S105).

In the present invention, the radiation pattern may be any of the following.

1. Outputs a traveling sound toward a target area (center or bird cluster) from a speaker arranged outside at least one side of the area to be eradicated, and when the traveling sound reaches the target area, the blow sound is simultaneously or sequentially performed in the target area. Print

2. Proceeds through the target area from the starting speaker arranged outside at least one side of the area to be eliminated and outputs the sound toward the speaker installed at the opposite position of the starting speaker.

3. Output the sound in a whirlwind form from one end of the area to be eradicated toward the target area, and when the sound reaches the target area, the sound is simultaneously or sequentially output from the target area.

4. The speaker arranged at each unit cell of the area to be eradicated outputs a random hitting sound, but controls to move from a far distance from the target area to a position close to the target area.

That is, the present invention has a fast learning effect on a fixed object, while the bird is sensitive to a moving object every moment, and the bird is not sensitive to a distant object and is sensitive to an object in proximity to itself. By using the characteristics and the characteristics that the birds feel close to the movement of the birds as they move close to the speaker as shown in Figures 2 to 4, and the decay sound is moved toward the target area (center or bird cluster) Emits a surround sound pattern in the form of a passing light.

Existing acoustic bird elimination device has a sound source is fixed in one place, the sound is radiated from a long distance there is less threat of birds, and the radiation pattern is simple, the learning effect is fast. On the contrary, the algae extermination system according to the present invention may threaten to radiate the extinguishing sound because the sound source causes an effect of approaching the algae or moving through the algae. Therefore, it is possible to suppress the learning effect of the algae, because the repellent sound is emitted only toward the algae can also reduce the ambient noise.

6 is a flowchart illustrating a method for combating birds according to another embodiment of the present invention, which shows a method for combating the occurrence of birds by a surveillance camera.

As the appearance of the bird is detected by the surveillance camera 180 (S201), the combat command processor 150 generates a combat command (S203).

Accordingly, the controller 110 operates the pattern selector 160 to select the radiation pattern stored in the memory 120 by the pattern selector 160 (S205). In this case, the pattern selector 160 may select any one of various eradication sounds stored in the memory 120 in addition to the radiation pattern.

As the radiation pattern is selected, the controller 110 sequentially drives the speaker 174 to output the radiation pattern with reference to the speaker manager 140 to radiate a repellent sound (S207). The radiation pattern may be any one of the four types described above, but is not limited thereto.

After the extinguishing sound is emitted, it is determined whether the extinction is successful according to whether the bird is captured by the surveillance camera 180 (S209). In addition, when it is determined that the bird extermination is successful, the extermination command processing unit 150 reports that the task is completed to the control unit 110 (S211) and transitions to the standby state. On the other hand, in the case of failure to combat the algae proceeds to the step of selecting a radiation pattern (S205), so that the sound is output in a pattern different from the previous step.

In the present embodiment, when the bird is captured through the surveillance camera 180, it is also possible to determine the type of the bird, in this case, of course, the bird database and the bird discrimination unit should be further provided. In addition, when the type of algae is determined, the pattern selector 160 selects a radiation pattern and a combat sound corresponding to the characteristics of the algae.

If surveillance cameras are not used, the bird clusters visually confirmed by the operator are set as the target area, or a stray sound is emitted to a random or preset target area. However, when the surveillance camera is used, the bird cluster can be systematically checked, so that the algae cluster identified by the surveillance camera is the target area so that the torch is radiated toward the target area or through the target area in a surround form. There is an advantage to control.

As described above, in the present invention, the combat sound can be output in four radiation patterns.

First, FIG. 7 is a diagram for describing a case in which progress sounds sequentially output from a plurality of speakers installed on a path between a designated target region from a unit cell outside at least one side of an area to be eradicated are output in a radiation pattern.

First, (a) of FIG. 7 is a 'shu-wook' sound progressing from the speaker disposed in the unit cell A on the outer side of the region to be eliminated, passing through the cell B to the target area C. After outputting the output sound hitting 'tang' in the target area (C) at the same time or sequentially output.

The traveling sound can be output by sequentially driving the speakers arranged in each unit cell (A, B) from the outer unit cell (A) to the target area (C). In addition, in order to output the hitting sound, all the speakers arranged around the target area C may be driven simultaneously (simultaneous hitting sounds) or the speakers arranged around the target area C may be sequentially driven (sequential hitting sounds).

FIG. 7B shows a traveling sound output from the speakers disposed in the unit cells A1 and A2 on both sides of the planned area to be passed through the next cells B1 and B2 and toward the target area C. FIG. The following shows a case in which the hitting sounds are output simultaneously or sequentially in the target area (C). In addition, (c) of FIG. 7 passes from the unit cells A1, A2, A4, and A4 at the upper and lower edges of the planned eradication area to pass through the next adjacent cells B1 and B2 toward the target area C. After the sound is output, the hitting sound is output simultaneously or sequentially in the target area (C).

Next, FIG. 8 illustrates a pattern of the sound of a sound that is sequentially output from a speaker installed on a path between a designated target area and a unit cell at a position opposite to the starting unit cell from a starting unit cell outside at least one side of the area to be eradicated. This is a view for explaining the case of outputting.

Referring to FIG. 8, the traveling sound is radiated from the first outer cell A1 of the area to be eradicated to cell A2, a target cell C, cells A3, and A4 opposite to A1. At the same time, the traveling sound is emitted toward the cells A4, A3, C, C2 and A1.

Furthermore, it is also possible to simultaneously output the traveling sound toward cells B1, C, and B2 and the traveling sound toward cells B2, C, and B1 so as to perpendicularly intersect the traveling sound to cells A1-A4 passing through the target area C. Do.

FIG. 9 is a view for explaining a case of outputting a sound pattern of sound progressively output from a plurality of speakers installed on a path formed in a whirlwind form from one end of the scheduled to be removed area toward a designated target area.

Referring to FIG. 9, A2-A3-A4-A5-A6-A7-A8-A9-A10-A11... It can be seen that the eradication process proceeds as if the sound is narrowed into the target area (C). In addition, when the whirlwind-formed sound reaches the target area (C), the blow sound is output simultaneously or sequentially in the target area (C) to further increase the threat.

The whirlwind of the whirlwind form is not limited to the above-described form and FIG. 8, and may be variously modified to have a tonal sense of progression narrowed in a whirlwind form from a distant place to a target region.

FIG. 10 is a diagram for describing a radiation pattern that is output while a blow sound is randomly output from a speaker arranged in each unit cell of a region to be eradicated, while the blow sound is moved from a place far from a designated destination area to a position close to the target area; to be.

Referring to FIG. 10, it can be seen that the striking sound starts from a distance far from the target region C, and the striking sound output position is gradually controlled to the target region C (in the order of ① ~ ⑨). Therefore, the birds to be killed can feel the threat to the random blow sound and at the same time the effect that occurs while moving the blow sound and the effect that comes closer to it can increase the bird fighting efficiency.

As such, those skilled in the art will appreciate that the present invention can be implemented in other specific forms without changing the technical spirit or essential features thereof. Therefore, the above-described embodiments are to be understood as illustrative in all respects and not as restrictive. The scope of the present invention is shown by the following claims rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included in the scope of the present invention. do.
