Description

{Method for getting rid of harmful insect}

The present invention relates to a pest control method, more specifically, it is possible to determine the type of a pest based on the sound of a natural frequency band in which a pest is generated, thereby effectively eliminating the pest according to the type of the pest, The present invention relates to a pest control method capable of simultaneously eliminating various kinds of pests.

Pests are insects that are harmful to human life directly or indirectly. Pests are classified into three categories: vomiting (mosquitoes and fleas), crossing (bees and mites), and weaning . It is not only dangerous because the insect pays toxins into the human body, or it causes bacteria that cause infectious diseases in the process of sucking the human body's blood. It also causes inconvenience because it causes itching or pain when it is bitten by insect pests.

Especially, in a high temperature and high humidity environment, various kinds of insect pests have been developed and sold in order to increase the number of insect pests by increasing the number of insects. However, pests are small in size, fast in movement, and most of the pests are active at night, so it is difficult to identify the kinds of pests by looking at the human eye.

In the case of insecticides, one of the most basic insect pest control methods, the toxicity of insecticides causes many limitations to be used not only to combat insects but also to harm the human body. Therefore, various methods have been developed and used to exterminate pests without harming the human body. One of them is to use the sound of the frequency band that pests do not like to use to pest insects.

For example, mosquito bites that are generally human beings are known as mosquitoes before the spawning of human blood. The mosquitoes before the spawning are known to avoid the male's warts and particularly fear their natural enemies. Therefore, it is the principle of mosquito repellent using sound that the female mosquito avoids its surroundings by repeatedly generating the sound corresponding to the wing frequency of the male hairdresser or the wing frequency of the female hairdresser. In recent years, a variety of smartphone applications have been developed and used to combat mosquitoes.

Such an application for mosquito eradication operates in such a manner that the sound of the frequency band that the mosquito dislikes is output through the speaker to block the mosquitoes from approaching the user. Since there is not only a mosquito in the pest, it is difficult to eradicate the insect other than the mosquito by using the mosquito repellent application. In addition, there are various kinds of mosquitoes, and it is difficult to effectively combat mosquitoes simply by operating a mosquito repellent application specialized for a specific mosquito.

Furthermore, since it is difficult to discriminate the kind of small insect pests moving in a dark environment, it is difficult to judge the type of insect pests and to use an eradication method corresponding to the type of insect pests judged.

The present invention has been made in view of the fact that insect pests generate sounds in respective frequency bands. The object of the present invention is to first determine the kind of pests based on the sound generated by insects, And to provide a pest control method for pest control.

It is another object of the present invention to provide a pest control method for judging various kinds of pests and simultaneously eliminating various kinds of pests even when various kinds of pests are mixed.

Another object of the present invention is to calculate the increase / decrease in the intensity of the acoustic information of the pests periodically generated per unit time, and thereby, when the urgency of the insect pest approaching to the user is high, The present invention provides a pest control method capable of effectively eliminating pests while reducing the number of pests.

In order to accomplish the object of the present invention, a pest control method according to the present invention includes the steps of acquiring sound of a pest through a microphone and analyzing the acquired sound to generate sound information of the insect, Searching for pest sound information mapped to the sound information by comparing the pest sound information with the pest sound information stored in the sound information storing unit; and detecting an erasure frequency band for eradicating the pest based on the detected pest sound information when the pest sound information mapped to the sound information is searched .

Here, the acoustic information of the insect is characterized by being at least one of formant, intensity, pitch, and duration.

Preferably, the acoustic information of the pests is characterized by being normalized to the same unit value.

The insect pest control method according to the present invention further includes a step of determining the date of obtaining the sound of the pest, wherein the sound of the frequency band for eliminating insects based on the date of obtaining the sound of the insect pest and the searched pest sound information And outputs the sound of the searched frequency band as an erasure sound.

The step of retrieving pest sound information mapped to the sound information in the present invention comprises the steps of retrieving a single pest sound information of a single pest mapped to the sound information and a single pest sound information mapped to the sound information when the single pest sound information is not searched. And searching the combined pest sound information by combining the pest sound information of the pest. Outputting an erasure sound for erasing a single insect mapped to a single insect sound information when single insect sound information is searched, and outputting an erasure sound for eradicating the combined insect mapped to the combined insect sound information when the combined insect sound information is searched And outputs an erasure sound.

The pest control method according to the present invention further includes a step of calculating the increase / decrease in the intensity of the acoustic information of the insect pests cyclically generated per unit time and determining whether the insect is approaching or not based on the increase or decrease in intensity, And outputs an erasure sound.

The pest control method according to the present invention further includes a step of retrieving an additional pest control method for pest control based on searched pest sound information in an pest control database, and further provides a method of pest control to a user.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a pest control method according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a functional block diagram for explaining a pest control device according to the present invention.

Referring to FIG. 1, the sound acquisition unit 110 acquires sound that generates insects. Here, in an example of the sound acquisition unit 110, the microacoustic acquisition unit 110 acquires sound of a natural frequency band in which insects are generated. For example, a pest can generate sound in its natural frequency band due to its wings, or generate a sound in a natural frequency band.

The acoustic information generating unit 120 analyzes the acquired sound and generates sound information specifying the acquired sound. In accordance with the field to which the present invention is applied, formant, intensity, pitch, and duration are used as acoustic information. Various types of acoustic information according to the field to which the present invention is applied Can be used.

If we look at the formant, the vibration source (vibration source) has a peculiar vibration characteristic (or resonance characteristic). When the sound is analyzed by the frequency, it means a graph indicating how much energy exists at a certain frequency. The resonant frequency band is referred to as a first formant 1, a second formant 2, a third formant 3, etc. from a lower frequency side. The intensity refers to the sound intensity in a certain section, and the pitch refers to the natural frequency of the sound felt by the person, which is also called the pitch. Also, the duration refers to a period of negative repetition.

Meanwhile, according to the field to which the present invention is applied, the acoustic information generating unit 120 generates acoustic information on the date when the acoustic information is acquired through the acoustic acquiring unit 110.

 The search unit 140 searches for pest sound information mapped with the generated sound information. The search unit 140 searches the single pest sound information mapped with the sound information by comparing the generated sound information and the single pest sound information of the single pest stored in the database 150. If there is no single pest sound information to be mapped with the sound information, the search unit 140 generates a combined pest sound information by combining the single pest sound information stored in the database 150, To retrieve the combined pest sound information.

Preferably, the pest control apparatus according to the present invention includes a normalization unit 130, which normalizes the acoustic information having a different range to a single range. In this case, the normalized pest sound information is stored in the database 150, and the search unit 140 searches the pest sound information mapped to the normalized sound information.

If the pest sound information mapped with the sound information is searched, the type or the identity of the insect pest is determined based on the pest sound information, the extracted sound spectrum of the frequency band for eliminating the determined insect is extracted from the database 150, Lt; / RTI > Preferably, the database 150 further stores an additional purging method for purging the determined pests other than the purged sound. According to the purging method, the additional purging method may be output through the speaker 161 or output through the display 163 do.

2 is a flowchart for explaining a pest control method according to the present invention.

Referring to FIG. 2, the user obtains a specific sound in which a pest is generated (S110), and analyzes the acquired sound to generate sound information (S120). Acoustic information can be various acoustic analysis programs that generate acoustic information such as formants, pitches, intensities and durations of sounds. In the present invention, Professor Paul Boersma and David Winnik David Weenink (Praat), a professor of computer science. In an embodiment of the present invention, the first formant, the second formant, the third formant, and the pitch, intensity, and duration are used as acoustic information. In the present invention, the date information obtained by acquiring the sound is additionally generated as an example of the sound information.

The sound information such as generated formants, pitches, intensities, and durations is normalized and converted into a single range of values (S130). The range of the value of the formant and the range of the value of the pitch, intensity, and duration are different from each other. Therefore, the range of values of formants, the range of values of pitch, and the range of values of intensity. Normalize the range of values of the duration to values in the same unit range. An example of a method of normalization is shown in Equation (1) below.

[Equation 1]

Herein, the maximum value and the minimum value are respectively the maximum value and the minimum value of the range of values of the acoustic information, and the acoustic information value means the acoustic information value generated from the acquired sound.

The normalized sound information or the pest sound information mapped to the generated date information is retrieved from the database using the normalized sound information or the generated date information at step S140.

When the pest sound information mapped to the normalized sound information or the generated date information is searched, information on the kind of the pest, the number of the pest, and the like are determined based on the searched sound information, Or provides an output to the user in step S150. Here, an additional method of extermination may be used in accordance with the field to which the present invention is applied as a method for exterminating insects other than the extermination sound, such as "remove the smell from the body through a shower"

FIG. 3 is a flowchart for explaining an example of a step of searching for an elimination sound in the pest control method according to the present invention.

More specifically, referring to FIG. 3, it is determined whether a single pest sound information mapped to the normalized sound information is searched based on the normalized sound information (S131). A single pest sound information is stored in the database. A single pest sound information means sound information obtained from a sound of a single kind of pest.

If the single pest sound information mapped to the normalized sound information is searched, an erasure sound for eradicating the pest mapped to the searched single pest sound information is retrieved from the database (S135). However, if single pest sound information mapped to the normalized sound information is not found, the single pest sound information stored in the database is combined to generate combined pest sound information, and the normalized sound information among the combined pest sound information It is determined whether the combined pest sound information to be mapped is searched (S135). When the combined pest sound information is searched, an elimination sound mapped to each single pest sound information based on the single pest sound information constituting the combined pest sound information is searched in the database (S133).

If there is a valid period in the retrieved sound, and if the current date corresponds to the valid period based on the date information, the retrieved sound is extracted and output (S139). In the present invention, when the normalized sound information is mapped to the combined pest sound information, the respective paused sounds mapped to the single pest sound information constituting the combined pest sound information are simultaneously output or periodically output with a time difference.

In the present invention, it is possible to effectively eradicate pests by outputting the erasure sound corresponding to the date information in consideration of the date information. For example, if a single pest sound information mapped to normalized acoustic information is determined to be a female mosquito in the spawning season and based on the date information, if the current date is before or after the spawning season, the female mosquito Instead, it outputs the sound of the nemesis of the bedrock.

In addition, there are cases in which not only a single kind of insect exists, but also a plurality of different kinds of insects are mixed together. The present invention relates to a method for combating single pest sound information and a combined insect pest sound generated from a plurality of different kinds of pests By searching information together, it is possible to judge and eliminate different kinds of pests not only when a single kind of insect exists but also when different kinds of insects exist.

4 is a view for explaining an example of a method of controlling the output of the sound to be eliminated in the pest control method according to the present invention.

The intensity of the normalized acoustic information is measured every periodic unit time, and the increase / decrease slope of the intensity is calculated (S213). It is determined whether the intensity of the sound acquired from the insect is increased based on the calculated increase / decrease slope of the intensity (S215).

If it is determined that the intensity gradually increases, it is determined that the insect pest is close to the person, and output control is performed for the searched sound (S217).

The pest control method according to the present invention has a disadvantage in that power consumption is severe when the pest control method is continuously performed such as sleeping, studying, and outdoor activities. Therefore, only when the insects are judged to be close to each other based on the increasing / decreasing gradient of the intensity of the sound information, the searched sound is output, thereby safely eliminating the insects and reducing the power consumption.

The above-described embodiments of the present invention can be embodied in a general-purpose digital computer that can be embodied as a program that can be executed in a computer and operates the program using a computer-readable recording medium.

The computer-readable recording medium may be an electrically or magnetic storage medium such as a ROM, a floppy disk, a hard disk, etc., an optical reading medium such as a CD-ROM or a DVD and a carrier wave, , Transmission over the Internet).

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
