Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the field of agricultural and forestry technology for protecting agricultural and forestry crops from harmful animals such as boars and deer that feed on agricultural crops such as rice and vegetables and forestry crops of saplings, cypress and other planted trees. is there.

[0002]

2. Description of the Related Art Conventionally, as a method of keeping pests away from the vicinity of agricultural and forestry crops to be protected, it has been said that the pests are surprised and moved away by direct means such as shooting by hunting, or by explosive sound of gunpowder or acetylene gas. Was common. However, the former cannot be applied during the hunting season, and since the area where private houses are built is changing into the hunting zone in recent years, future use will be further restricted. Also, the latter cannot be implemented all the time, and its effect is limited.

Another method is to surround the agricultural and forestry crops to be protected with a protective fence. However, this method entails a large amount of money because it encloses a vast area. If the fence on the slope of the mountain is not set too high, the deer can easily get over the fence, and the trouble is that the boar prey on earthworms nesting in dead leaves that gather under the fence.
Dig up the soil under the fence. Then, the deer will pass through this gap and so on. Especially,
Deer not only eat cedar and cypress saplings, but also rice and vegetables.Because people come and go in such farmland so much that it obstructs passage, it is not possible to stretch the fence entirely. , There are difficulties.

As a method other than the above, one that is in the range of practical use is to spray a repellent agent that gives off an odor that harmful animals dislike. Since it has relatively low toxicity, it can be sprayed near a water source, but it is expensive at around 5000 yen per kg,
In addition, it usually works only for 6 months, and if rain or the like continues, the effective period becomes short and the maintenance cost is high.

[0005]

DISCLOSURE OF THE INVENTION As described above, the method for exterminating a pest is for a short period of time such as shooting and blasting by hunting.
The sporadic method has no continuity of effect, so the method must be continuous in effect. In addition, it is necessary to use an inexpensive thing such as a fence, which is not expensive and does not restrict human behavior. Also, the effect should not be diminished with time like repellents, but the effect must be durable.

The present invention has been made in order to solve the above problems, and a pest-repelling voice should be emitted from a loudspeaker unit arranged around an agricultural and forestry crop to be protected to protect the pest. The purpose is to provide a method for exterminating agricultural and forestry crops from the surrounding area.

[0007]

[Means for Solving the Problem] The gist of the present invention is that a voice recorded by a pest that has been recorded in advance is repelled from a loudspeaker unit disposed around an agricultural and forestry crop to be protected. Further, the approaching pest is detected by the sensor unit, and a sound that the pest avoids is played from the loudspeaker unit by the detection signal. In addition, a sensor unit that detects an approaching pest and a loudspeaker unit are placed around the agricultural and forestry crops to be protected, and the detection signal from the sensor unit that detects the approaching pest causes the approach Sounds that the pest avoids are played in order from the loudspeaker unit that is close to the pest.

[0008]

Embodiments of the present invention will be described below. 1 and 2 show an example of the sensor unit 1 and the loudspeaker unit 2 used in the present invention. Since the sensor unit 1 and the loudspeaker unit 2 are frequently arranged in a mountain area away from a remote place, a solar unit 3 using a solar battery is used as a power source. This solar unit 3 is not much different from those already on the market. In the solar unit 3 of the embodiment, nine amorphous solar cells (output: 1.5V, 400mA) are connected in series, and the power is charged to the battery through a battery protection device so as not to overcharge or overdischarge.

The sensor unit 1 is operated by this power source. A pyroelectric infrared sensor 4 was used as the sensor unit 1. This is most suitable for use in the present invention because it operates when a person or animal that emits infrared rays moves within the sensing range of the sensor (radius about 7 mm). However, almost the same purpose can be achieved by using an optical sensor or an ultrasonic sensor.

Each sensor unit 1 is given a unique number. The loudspeaker unit 2 is also given a number corresponding to the unique number of the sensor unit. By giving the sensor unit and the loudspeaker unit unique numbers corresponding to each other, the pest recorded in advance from the loudspeaker unit that is close to the number of the sensor unit that detected the approach of the pest is avoided Can play voice.

When the infrared sensor 4 of the sensor unit operates, the number of that sensor unit is changed through the amplifier 5.
The signal is transmitted from the transmitting antenna 6 as a signal for wireless output for a fixed time. The radio may be a weak radio wave type or a specific low power radio station type.

On the other hand, the loudspeaker unit 2 shown in FIG. 2 has a receiving antenna 7, and the loudspeaker unit 2 having a number corresponding to the sensor unit number receives a sensor operation signal from the receiving antenna 7 (sensor unit signal). number)
Receive. This signal is randomly selected from a voice synthesis IC in which several types of voices that pests avoid are recorded in advance through an amplifier 8 through a control device, and the voices are output from a speaker 9 through a power amplifier. Shed. Like the sensor unit 1, the loudspeaker unit 2 also receives power from the solar unit 3. The sound that the pest avoids is not limited to the bark of a hound or a predator, but may be an artificial sound that the pest avoids.

Further, since the infrared sensor 4 does not have a wide sensing range, an approaching harmful animal may pass through the mesh of the sensor unit. Therefore, the loudspeaker unit 2 has a built-in timer for every predetermined time. In addition, one kind of voice randomly selected from the voice synthesis IC is played from the speaker 9. In this way, pests that have passed through the mesh of the sensor unit are prevented from entering the area of agricultural and forestry crops to be protected.

FIG. 3 shows an image of the arrangement when the sensor unit 1 and the loudspeaker unit 2 are arranged in Yamano. That is, the sensor unit 1 and the loudspeaker unit 2 are arranged so as to surround the area 10 of agricultural and forestry crops to be protected,
For example, when an approaching pest is detected by the A sensor unit 1, B and C that are closer to the A sensor unit 1 first are detected.
The voice is output from the loudspeaker unit 2 of No. 1 and then the voice of the loudspeaker unit 2 of D, E, and F. In this way, pests are prevented from entering the area 10 of agricultural and forestry crops to be protected.

The sensor unit may be appropriately arranged so as to surround the area of agricultural and forestry crops to be protected, but in the terrain of the mountains, there is a beast road or a road where deer may pass, so it should be arranged near it. It is effective.

[0016] In recent years, the number of deer has increased, and the damage has been heard in various places. Therefore, in order to protect the agricultural and forestry crops from the deer, the sensor unit 1 and the loudspeaker unit 2 are arranged as shown in FIG. 3, and the bark of the hound that the deer avoids is made to flow from the loudspeaker unit 2. Deer are sensitive to the barking of hounds, so even if they can be heard in the distance, they are shy and do not approach. Therefore, even if the barking voice of the hound is made to flow at regular intervals by the timer, there is a sufficient effect of destroying the deer. Furthermore, when a deer approaches the sensor unit 1, it is detected, and the bark of the hunting dog is caused to flow from the loudspeaker unit 2 in conjunction with this, so that the effect of exterminating the deer is doubled. Also, as for voices, one kind of voice is randomly selected from the voice synthesis IC in which several kinds of voices that the pests avoid are previously recorded, so that the problem of pest familiarity does not easily occur.

FIG. 4 is an external view of the sensor unit and the loudspeaker unit, and shows an example in which the sensor unit and the loudspeaker unit have the same shape. The unit is a solar unit 3,
Housing 12 that houses the sensor unit or loudspeaker unit
And a pole 13 that supports the solar unit 3 and the housing 12.
Composed of and, the unit is erected on the ground by pole 13. The solar unit 3 has a solar cell 11 on the surface.
And transmitting / receiving antennas 6 and 7 are provided on the upper part. In the case of a sensor unit, the sensor unit is housed in the housing, and the infrared sensor 4 is arranged on the side surface of the housing 12. In the case of the loudspeaker unit, the loudspeaker unit is housed in the housing, and the speaker 9 is arranged on the side surface of the housing 12.

[0018]

As is apparent from the above description,
According to the present invention, it is possible to exterminate pests simply by arranging the sensor unit and the loudspeaker unit around the agricultural and forestry crops to be protected. Therefore, it is cheaper than the fences and the human behavior is reduced. Nothing is constrained, and the effect of destroying pests is continuous.
