Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a harmful animal repellent having a super directional speaker rotated in the direction of a detected sound,

More particularly, the present invention relates to a super directional speaker capable of detecting a sound from a plurality of directional microphones installed in the north, south, east and west directions and capable of rotating in a direction in which a sound is detected, The direction of the sound of the directional microphone in which the loudest sound signal is detected is detected and the rotation angle is adjusted according to the control of the control unit. Directional speaker in the direction of the sound detected by the motor drive and modulates a sound signal for eradicating the harmful animal from the harmful animal suppressor provided with the supergiant animal speaker rotated in the direction of the sensed sound Outputs sound with directivity in specific direction in which harmful animals are put on ultrasonic signal And a super directional loudspeaker rotated in the direction of the sensed sound to reduce the damage of the crops that are driven out of the cultivated land according to the cultivated land.

 It is reported that the damage caused by harmful animals is seriously affected by the TV and various media. Especially, the wild boar or elk came down to the fields of the crop harvest and ruined the crops that have been swollen for a year. . Nationally, the amount of crop damage caused by harmful animals is said to be several hundred billion won.

This damage has not lasted for a long time, but the government and municipal governments have allowed for capturing of wild animals such as wild boar and elk for a certain period from 10 years ago to prevent further damage.

The capturing of harmful animals may reduce the damage to the crop to some extent, but it does not provide a 100% satisfactory effect and there are many ways to reduce crop damage from harmful animals. This method can cause damage to the residents due to the noise. There is a need to replace the harmful animals after a certain period of time. Fence installation is useless. Install a powerful LED warning light that is most effective, low installation cost, and simple to install. The LED warning light has no secondary damage such as noise and can be used safely because it can be used semi-permanently once installed.

The solar LED warning light automatically recognizes the surrounding erection even if the user does not turn on / off the power of the pest. It turns on when it is dark, and automatically turns off when it is bright, so there is no need to manage it separately. Can be used semi-permanently.

FIG. 1 is a conceptual diagram for preventing access to wildlife and algae by light and ultrasonic sounds (animal anxiety).

There are two ways to combat harmful bird wildlife: strong LED fleshing, and ultrasound acoustics that animals dislike. There are also animal pests that prevent access to animals that damage crops such as wildlife and wild birds.

The pest control unit has a solar cell unit for outdoor use that uses sunlight as a power source.

2 is a photograph of a product of an ultrasonic noxious animal repellent machine equipped with a PIR sensor.

This product is Sonic-T's Ultrasonic Pest Control System (Ultrasonic Cat Suppressor). It can be used as a pest suppressor using an ultrasonic wave, a cat eliminator, an organic dog eliminator, an algae eliminator, and a rat suppressor.

Ultrasonic poultry rescue machines equipped with PIR sensors are used to eliminate harmful animals such as cats and birds within 10m detection range when there is no obstacle in the front, by generating powerful ultrasonic waves and flashes.

The product has a temperature range of 65 ° F (18.3 ° C) to 97 ° F (35 ° C) and is suitable for indoor use for normal monitoring within a 10m sensing range using a PIR sensor. If this product is used outdoors or if it is used at a temperature higher than the above temperature, stable measurement may become difficult. In particular, direct sunlight should be avoided.

Human body detection sensors include PIR sensors, ultrasonic sensors, and microwave sensors.

- Use of human body sensor (PIR sensor, HC-SR501 for example)

When a person (or an animal) is detected in an apartment hall or a front door, the sensor turns on the light and turns it off after a certain period of time is called a PIR sensor. The human body has 36.5 degrees of heat, so infrared rays are emitted. PIR sensor is a sensor that detects the infrared ray and sends a signal to illuminate the human body when the movement is detected. Released as a PIR sensor, the HC-SR501 is adjustable in sensitivity and can control the time it takes to send a signal when the human body is detected. The HC-SR501 will send a signal for a certain time even if the infrared detection is completed within a distance of 10m or less. Therefore, when you go through the apartment hall, the light turns on, and when there is no person, it turns off after a while.

For example, as an example of PIR sensor application, LG Electronics 'Whisen Dual Air Conditioner' is equipped with a human body detection camera that detects the number, position, and activity of people in a range of up to 5m and up to 105 ° Smart Dual Custom Cooling ',' Smart Dual Sleep Cooling ', and' Smart Dual Power Cooling 'are provided by automatically determining the wind direction and direction after grasping the indoor situation by finding the shape of a person in real time.

The human body sensor is a sensor that reacts when there is a change in the infrared rays. When the human body sensor is installed outdoors, the human body sensor in the sunlight has many malfunctions because the sunlight includes light in all frequency bands There is no meaning.

As a related art 1, Patent Registration No. 10-1443199 discloses " a harmful animal and pest insect fighting system including a repellent spraying unit ".

As a related art 2, Patent Literature No. 10-1630274 discloses a " illumination device using an infrared sensor and an ultrasonic sensor ".

3 is a configuration diagram of a conventional illumination device using an infrared sensor and an ultrasonic sensor.

An illumination device using an infrared sensor and an ultrasonic sensor includes an LED illumination unit having at least one LED module, an infrared sensor and an ultrasonic sensor disposed inside the LED illumination unit for sensing a moving object, and the sensing range of the infrared sensor is an ultrasound The sensor unit designed to include the sensing range of the sensor and the moving object are moved to the sensing range of the infrared sensor, the LED module is turned on at the first illuminance and the timer is operated to light up to a predetermined time, The LED module is turned up to the second illuminance higher than the first illuminance so as to illuminate, and at the same time, the time of the timer is initialized to continuously maintain the illuminance at the second illuminance , When the moving object moves within the sensing range of the infrared sensor within the sensing range of the ultrasonic sensor And a control unit for controlling the LED module to be down-adjusted from the second illuminance to the first illuminance so as to re-operate the initialized timer and to light up to a preset time.

People do not want to hear the blackboard or glass scraping, rubbing sound, glass scraping, tooth whining, etc., but they get scared when they hear rubbing between smooth and hard materials.

The sound has a tone, for example, a piano 'do' sound or a violin 'do' sound is a sound having the same frequency, but a sound corresponding to a sound wave having the same frequency has a different sound, I feel differently. The tone of the sound is not the sound of a piano, but the sound of a violin or the sound of a violin is not actually a sound wave with a single frequency, but a composite sound with many sounds.

If the shape of the synthetic wave is different, people feel the tone is different. This is because the sound of scratching on the blackboard and the sound of hitting the window are usually the ones people dislike. However, in general, the tone that people feel is achieved through learning, and the feeling can be different for those who judge these sounds well. In other words, some people like piano sounds, but some people do not like piano sounds.

Until the late 1980s, little scientific research on this problem had been made, but most scholars thought that the high frequencies included in this sound were disgusting to listeners. However, in 1986, a psychoacoustic experiment was conducted at a Northwestern University laboratory to confirm that the experiment was incorrect. I recorded the scratching sound on the blackboard, played it through different frequency processing devices, and experimented with it.

Experimental results show that even when the high frequencies are removed from the sound, people are uncomfortable, and even when the volume is changed, no change can be observed. In view of this, it is interpreted that high frequency or volume is not the cause of horror. In the experiment, however, it was found that the scratching on the blackboard was very similar to the sound of a Japanese monkey, a descendant of a primate, in fear. Through this, scholars thought that the ape-like reaction to the scratching on the blackboard could be a primitive reaction that was formed in the evolutionary history of mankind. That is, it may resemble the sound of wild predators threatening mankind, and the early experience of mankind, which had to be sensitive to the sounds of predators, remains to this day. However, this explanation is only a mere guess, and the research and understanding of this problem has not been done yet.

Obtained patent for development of Smart Trap to catch pest, / Visiting promising company that is the future with eco-friendly farming material

Consumers are increasingly concerned with the growing awareness of eco-friendly agricultural products nationwide, and consumers' demand for safer and more healthy foods is constant. In the end, in order to produce such eco-friendly agricultural products, the eco-friendly farming industry is naturally forced to develop. However, the eco - friendly farming industry is also experiencing difficulties for small and medium - sized companies as large companies enter the market. The young farmers in the region have participated and the eco-friendly farming industry has been developed based on their know-how and experience.

Recently, a "rocket trap" has been developed, which can capture a large amount of pests, which are a problem of cultivation of fruit trees and beans, irrespective of kinds. Agricultural corporation VITUM and Rural Development Administration National Institute of Food Science and Technology (KFRI) jointly developed the trap of trapping rocket in October last year and obtained patents after three years of validation.

At present, 'Norinja' in Korea is causing great damage to fruits, beans and beans such as persimmon, apple, citrus, plum, peach, blueberry, and kiwi. However, the rocket traps, which are launched from this month, are expected to contribute to solving the problem of the stray wood because it can best catch the 'depleted wood' and 'brown winged wood', which could not be captured until now. In addition, "top leg ants back" is also evaluated as a general-purpose trap that can capture the best, proved excellence. Founded in November 2011, VITUM is a local agricultural company located in Myeon Suk-myeon, Jinju city. It is a creative farming material for environment-friendly, automation, energy saving, functional and safety essential for smart farming and environment realization through original R & As a venture company that produces and distributes products, there is a pest catcher, ie, smart trap, which captures pests that greatly damage crops, forests, and the environment using solar light. In addition, as shown in FIG. 4, there are producing a harmful wildlife automatic firearm such as a wild boar, and a Wi-Fi CCTV and a motion lamp for real-time confirmation of a real situation of a specific place. In addition, there are growing crops such as blueberries, cherries, and azaleas, which are popular as high-income crops, medicinal crops such as quanmundong, white pine, pineapple, cornerstone, and bellflower, growth soil for growth and production of various leafy vegetables and fruit vegetables, ) It contributes to the enhancement of agricultural competitiveness through development of cultivation methods and production of products. "VITUM is taking the lead in resolving the agriculture hardship technology through the production of functional materials and equipment essential for environmentally and vigorously managing major pests that are obstacles to safe agricultural products. We will do our best to grow into a company with a strong presence. "

In addition, damage to crops is increasing year by year in farmland, and the use of noose or pesticide is illegal, and farmers who can not afford to install hundreds to tens of millions of won high-voltage wire walls are worried. "Blinkers using solar energy Will also help farmers.

"If you put it in a field or a farm where wild animals often appear at intervals of 10 meters, you can anticipate not only damage to crops but also crime prevention effect." In the unused winter season, it can be used again the next year after collection.

Farmer Kim said, "One or two birds fly in the sowing season, and the birds taste the beans at this time. If these birds are left alone, they will fly to 30 ~ 50 within at least one week, and the soybean fields will be destroyed by the end of the year. Later, when we see a field that grows only weeds instead of beans, it only sighs. "

Nevertheless, the amount of damage has been significantly reduced since the use of preventive and countermeasures manufactured directly from last year. A constantly flickering lightning bulb prevents the first wildlife invasion, and a second lane sets out to fire once every five to ten minutes. It can be operated anywhere with electricity.

* Characteristics and harmfulness of harmful algae

1. Characteristics of birds

⊙ Algae (magpies, magpies, water magpies, horses, etc.) are highly visual and auditory, but the olfactory is degenerated and senses the taste with the tongue.

⊙ The bird's vision cell has four distinct cones that distinguish the color, and it can detect light in the ultraviolet region that human can not see, but it can not distinguish well when the light transmission is small because the number of the stem cells is small Driving ability).

⊙ Birds' ears are as good as their hearing, responding to small sounds and being used as a tool for communication among ethnic groups.

⊙ The breeding season has a variety of communication signals, not singing songs for courtship. It has excellent learning ability of sounds to mimic the sounds of natural enemies and other animals, and is used as an important means of survival.

⊙ Crows (magpies, crows, crows, water magpies) birds can use tools, find cognitive abilities to understand play behavior and "other objects have different intentions" It also has excellent spatial memory and is sometimes referred to as a "feathered primate."

⊙ A magpie takes a lot of time to defend a pair with a certain power and defend it and give a "warning sound" throughout the year. In addition, when an individual in the territory dies, the other peripheral entities flow in quickly to form new entities or become a cluster of non-recurring entities.

2. Damage due to harmful algae

⊙ The result of investigation on the damage rate of the bird by apple varieties varies by region and type of bird species, but in 2004, 20.8% of Tsugaru, 36.6% of Hong Kong, 22.5% of Fuji were examined by the horticultural research department of Kangwon Provincial Agricultural Technology Institute.

* problem

⊙ We are focused on one kind of fragmentary business in the eradication of harmful ancestral waters, and have not got comprehensive medicine.

⊙ The net installation method which shows the perfect effect is also a factor that hesitates to install at the farmhouse due to the heavy snow damage, but the more fundamental fact is that the price is expensive, and it is a case that the farmhouse is judged against the river in reality.

⊙ It is possible to relieve farmers by applying for permission to capture harmful birds, but the recognition is low due to lack of publicity.

⊙ Collectively, there are factors of price reduction when installing, but until now, individual installation is being carried out.

Therefore, a comprehensive control system is actively promoted to combat harmful tidal aquaculture, actively coping with the blocking of learning effect and active change of dominant species, minimizing the damage rate of crops and inducing price reduction of harmful animal exterminator by joint installation by district and small- Collective installation is necessary.

In recent years, various electric fence systems have been spreading in Korea to protect wild animals such as wild boar from damage by farmers. The newest electric fence is a concept of eliminating outside intrusion by installing one or more electric wires instead of building piles at regular intervals at the edge of the protection target such as pasture or farmland.

Recently, the electric fence, which is introduced through media reports, is a concern of farmers who can reduce crops and human injury caused by wild animals. But the problem is that there is no farmer who gives a firm view of the importance of electric fencing. In recent years, in relation to the wild boar damage incidents occurring nationwide, it has produced 40,000 years of rice paddies, potatoes, etc. in the fields and fields of 11,000 pyeong in Anheung-myeon, Kangwon-do, Gangwon province, claiming that they can prevent the attack of wild boars by installing electric fences. I visited the farmhouse. Rural leaders of this farmhouse have suffered more than tens of millions of won by wild animals such as wild boar and elk since the last 10 years, and the worst thing is that they have lost memories of young seedlings planted before harvest or a few hours ago.

In order to eradicate harmful animals such as wild boar, Jeon Chairman who installed electric fence on 3,000 pyeong of field and field by Hoengseong-gun auxiliary business according to the harmful tide prevention regulations in 2006 is in a relaxed state. Electric fencing with electric shocks of up to 8 to 9,000 volts should be replaced every three years. The cost of a solar cell generating an impact electricity, such as simply replacing a fuel cell in a control box, is 60,000 won. Currently, electric fences are installed in this area, because electricity is not supplied, so electricity generated by solar heat is used. There are also precautions. In order to generate the maximum electric shock, it is absolutely necessary to remove the foreign matter and to prevent glazing. In order to generate electric shocks of a certain 9,000 volts in the electric wire, it is necessary to minimize electricity escaping by the paste. It is also important to note that when the number of grass is increased, the maximum amount of impact is reduced depending on the amount of grass that has reached the electric wire. However, it is easy to see the sight of the elderly in their 60s and 70s burning tires and plates all over the place in order to eradicate Gorini and wild boar until spring harvest season and fall harvest time. "" It is easy to see the smell of poisonous fumes and toxic gas all over the fields It may seem like a fire, but it is a controversy to minimize the damage. " The wild boar digs in a row in a row with the habit of digging the nose and whip everything and eat it. On the way down, small farms without electrical fences were almost destroyed by wild animals. "After the installation of electric fences, there are no cases of damage to wild boars. Without the electric fence, damage would have occurred all year round. If you plant the cabbage all over the month, it will be eaten in a day and you will get rid of it in one day. If corn is planted in May, it will fall down in July and August when sweet grains will be produced.

However, in a certain period of time to catch the group behavior of wild boar more than 10, to prevent the appearance of wild boar in July 7-8 when corn sweet grapes when the toxic wild boar came down a lot, In June, the mother boar comes down to eat corn together after three to eight months after giving birth to 7-8, which is in harmony with our field farming and cycle. "However, in the case of elk, it is necessary to stand at a certain interval without installing a support stand in front of the steep slope (downhill). "It is not an electric fence if there is no electric fence," he said. "The fence falls easily on a slope, so you can collapse the electric fence when you fall." There are four farmhouses in Hoengseong County with electric fences installed. The electric fence should be emphasized that there must be a wire. If there is no bark, it is not an electric fence. It should be used as a resilient and rustproof material like poly wire.

However, the conventional technique uses an ultrasonic wave breaker for eradicating harmful animals, an LED warning light periodically turned on, a noise suppressor, an odor technique, and an electric fence. In contrast, the harmful animals emerged from fields such as rice fields and fields Directional loudspeaker rotated in the direction of the sensed sound by detecting the direction of the sound and detecting the direction of the sound by rotating the supergain loudspeaker having the directivity in the detected direction and thereby suppressing the harmful animal from the ultrasonic signal from the pest- But it did not provide the ability to drive away the harmful animals that appeared on the cultivated land as they output sound with directivity.

The pest suppressor having the supergain loudspeaker rotated in the direction of the sensed sound according to the present invention includes a plurality of directional microphones periodically installed in the direction of the north, south, south, east, west, And detects the sound of the noxious animal emerging from cultivated fields such as fields and fields equipped with a pest suppressor equipped with a super directional speaker capable of rotating in a direction in which a sound of a predetermined dB or more is detected, Directional loudspeaker is rotated in the direction of the detected sound by detecting the direction of the sound of the directional microphone which is detected by the motor driving according to the control by the control unit of the pest control unit, Sound for eliminating harmful animals from ultrasound signals from a poultry eliminator As modulates a call output sounds carried on the ultrasonic signal with a directivity is to drive out the harmful animals shown in the land reduce the impact of in crops.

Ultrasound is a sound wave whose frequency is above 20,000 Hz, which is the audible frequency (16 Hz to 16,000 Hz or 20 Hz to 20,000 Hz), which is usually heard by people. The frequency is high and the wavelength is short and it is transmitted far, but it is difficult to use it as a speaker if people can not hear it.

The ultrasonic wave usually uses 30 to 300 kHz, and the frequency is higher than that of the sound wave in the audible range. The wavelength and the wavelength are inversely proportional to each other. Directionality is a phenomenon in which sound propagates intensively in one direction, and the intensity of sound varies greatly depending on the direction. Sound waves are not usually propagated straight, but spread widely. In the case of ultrasonic waves, the wavelength is much shorter than the audible frequency, and the degree of spreading is very small.

Generally speaking, a person's voice can not be heard only by the person who wants it because it spreads to the left and right in addition to the direction of speech. This is the same for speakers, but a supergiant speaker has directivity in the desired direction and uses ultrasound to make sounds heard only in the far direction.

The supergiant loudspeaker solved the problem using two ultrasonic speakers. First, the sound for destroying the harmful animal to be transmitted to the harmful animal is modulated and transmitted on the ultrasonic signal. For example, this ultrasonic wave (30-50 kHz) and other ultrasonic waves (40-60 kHz) causing interference are shot together. This allows them to be distant from each other only in the desired direction and to interfere with each other to create a sound that people can hear.

Utilizing sounds, ultrasonic signals and pulsating beats to combat harmful animals.

According to one study, the beat of a wave in a directivity experiment is equal to the frequency difference between the two pulses whose frequency is beat. If the difference in frequency is the beat of two ultrasonic waves, which are audible frequencies, beat pulses will have audible frequencies. If you can hear this beating wave with your ears, the audible frequency that is beaten by the direction of the ultrasonic waves will also be directional.

For reference, supergiant speakers can be used in many ways. It is a way of guiding people with uncomfortable eyesight or letting the viewer see the corresponding artwork to explain the artwork exhibited. It is also possible to deliver the product advertisement displayed on the show window only to the viewer of the show window.

In the embodiment of the present invention, the microphones used in the pest control unit use a unidirectional microphone that receives only the sound of the front of the microphone, a 'omnidirectional speaker' that receives sounds in all directions, and a 'bidirectional speaker 'Is not used. Unidirectional microphones range from 10 to 20 degrees, 30 degrees, 45 degrees.

The supergain speaker (130) includes a modulation circuit (131) for modulating a sound signal (audio signal) for eradicating harmful animals; An ultrasonic wave PWM band signal processing unit 132 for synthesizing an ultrasonic wave band carrier wave in a range of 30 to 300 kHz to synthesize a sound signal for eliminating the harmful animal modulated in the ultrasonic wave signal; An amplifier 133 for amplifying a sound signal for eliminating the harmful animal modulated by the ultrasonic signal; And a piezoelectric speaker 134 for outputting a sound signal for eliminating the amplified modulated harmful animal with a directivity in a specific direction in which the harmful animal appears, and outputting a high frequency sound.

Ultrasound uses 30 ~ 300 kHz ultrasonic waves that can not be heard by human ears. The speed of sound waves in air varies with temperature (pressure, frequency, humidity).

The energy of the ultrasonic wave is larger as the frequency and the amplitude are larger. The piezoelectric speaker 134 has a function of generating a piezoelectric effect or a voltage when the ceramic crystal is compressed or elongated, a crystal or a ceramic crystal When an alternating electric field is applied, it provides a shrinking and stretching effect (negative effect).

In another embodiment, sound, ultrasound signals, and pulsating beats may be used to combat harmful animals to ensure the dirsctivity of the ultrasound waves. A beat is a phenomenon in which the sound of a synthetic wave becomes smaller and smaller by synthesizing two waves having almost the same frequency.

The supergain speaker includes a modulation circuit 131, an ultrasonic wave PWM band signal processor 132, an amplifier 133 and a piezoelectric speaker 134 as one ultrasonic wave in another frequency range which further interferes with one ultrasonic wave circuit, Two circuits can be used. First, the sound for exterminating harmful animals is modulated by putting on the ultrasonic waves, and the harmful animals are emitted into the air by the thickness vibration of the piezoelectric ceramics used in the high frequency wave range of up to 300 kHz in the direction of the detected sound. For example, other ultrasonic waves (40 to 60 kHz) that cause interference with this ultrasonic wave (30 to 50 kHz) can be discharged together into the air. The supergiant is the direction angle and the sound pressure level (SPL)

, P: measured sound pressure, and Pref: reference sound pressure 0 [dB] = 0.0002 [μbar] or 0.0002 [Pa].

Pest control can be made fresh by adding a few more features to what the company wants to develop. In addition, we want to develop it so that it can be used not only in agriculture but also in urban areas.

- Unlike conventional devices that always operate after sunset, microwave sensors or human body detection sensors are used to provide a standby state.

- Charge the used electric power of the pest suppressor with supergiant speaker by using sunlight.

- Use ultrasonic waves and sound, so-called super-directional speakers, not noise and light.

- Pest control equipment with supergiant loudspeakers is not a sound and light control system, so it can be used in urban areas.
