Description

[Detailed Description of the Invention] Industrial Application Field The present invention applies speech recognition computers to
This invention relates to a pest prevention device for preventing harmful birds in factories, airports, etc.

Conventional technology Traditionally, methods for preventing bird damage caused by harmful birds during paddy rice cultivation, cultivation of fields, or harvesting of orchards, etc., have been carried out by using bamboo grass, simple structures such as hanging claws of various shapes, or carbide orchards. There was a bomber using LP gas. There was also a method of using pre-recorded tapes to play the voices of the birds' natural enemies in order to drive away pigeons in factories and pests in airfield grasslands.

The conventional technology described above had the effect of temporarily preventing harmful birds from flying into the city, but if installed continuously over a long period of time, the harmful birds may see through the problem or become used to it, resulting in a drastic reduction in effectiveness. was there. In addition, when a bomber using Carby Toya LP gas is installed in an area close to a residential area, it produces an abnormal and continuous high-pitched sound from early morning until evening, causing complaints from private houses. The current situation is that still,
The method of playing natural enemy sounds on tape in factories and airfield grasslands had the disadvantage that if the same sounds were repeated all day long, the birds would get used to it and become less wary, making it impossible to expect long-lasting effects. Try to solve it! One of the causes of the drawbacks of the above-mentioned prior art is that the same pattern repeats over a long period of time without any change, so the harmful birds' keen instincts lead them to believe that the installations and devices are fake. This is thought to be due to the fact that it can be seen through.

The purpose of this invention is to prevent harmful birds from becoming accustomed to devices by analyzing the above-mentioned instincts of harmful birds and eliminating the same pattern of continuous movement.

A means to solve a problem.

The configuration of the present invention for achieving the above object will be explained based on FIG. 2) is sent to the audio output circuit (3), the signal from the audio output circuit (3) is sent to the speaker (4), and the audio recognition circuit [2] and the audio output circuit (31 are both power supply circuits (5). ).This is a pest prevention device having the above structure.

Function When using the pest prevention device of the present invention, in the situation where it is installed, in addition to the sounds of pest birds, that is, their calls, there are often car noises, human voices, and many other noises. Various sounds are collected by the microphone (1) and input manually to the voice recognition circuit (2), which is recognized by the built-in voice recognition computer. The output circuit (3) is activated and, for example, a pre-recorded alarm sound of a specific pest bird or a similar synthesized sound is transmitted to the required range through the speaker (4) for a certain period of time in an internal tape recorder. By hearing the unique warning calls of the released harmful birds, the harmful birds that have flown by are startled and flee elsewhere.

Embodiment To explain one embodiment of the present invention, the present device is housed in a single container, and several microphones and speakers are placed inside the container facing in a desired direction.

For example, when using the present device to expel sparrows, the device is first fixed at a predetermined position in a rice field at a constant height. In that case, the direction of the microphone and speaker should be set to cover the entire area of the rice field. Next, to explain the operating state of this device, various sounds such as wind noise, aircraft noise, and loud voices of automobiles are mixed together in rice fields as noise. However, the voice recognition computer installed in the voice recognition circuit (2) excludes sounds other than those of sparrows that have been stored in advance, and the voice output circuit does not operate. However, when a sparrow flies in and makes a sound, , the sparrow's voice enters the microphone along with the noise, the voice recognition computer detects the sparrow's voice, and the voice output circuit (3
), the audio output circuit that receives the activation signal rotates the built-in tape recorder, and plays pre-recorded sparrow-specific warning calls and the voices of natural enemies over a speaker for a certain period of time. The setting of the release time can be controlled by the length of the activation signal from the computer, or the tape recorder can be controlled by a separately installed timer.

Effects of the Invention Since the present invention has the above configuration, it has the following effects.

(a1) At the installation location of the device of the present invention, a warning sound is emitted for a certain period of time only when a harmful bird flies in to drive away the harmful bird, and it is dormant when the harmful bird is not present, so it prevents the harmful bird from getting used to it. , so the effect can be maintained for a long period of time.

[BL Since the sound emitted is a copy of natural bird calls,
There is little risk of causing noise pollution to workers and nearby residents.

(CL) It can be used safely even in noisy places because it can only identify and react to the sounds of harmful birds and the flapping of their wings in the noise of cars, airplanes, and human voices.

(By replacing the dl recording tape, etc., there is no need to change the device itself, and by combining various voices, the effect can be maintained for a long time, and even if the target animal changes, it can be reliably adapted.) The pest prevention device of the present invention eliminates the drawbacks of the conventional technology, goes beyond the wisdom of pest birds to prevent habituation, effectively maintains the effect of pest prevention for a long period of time, and uses soft sound emission. This is a new and safe device that can be used in a variety of environments, reducing the risk of pollution.
