Description

  The present invention relates to a biological exclusion device that excludes animals to be excluded (hereinafter referred to as “exclusion target organisms”), and more particularly to a biological exclusion device that uses sound.

  2. Description of the Related Art Conventionally, biological exclusion devices for the purpose of eliminating harmful animals (for example, organisms to be excluded such as cockroaches, rats, birds (crows, starlings, pigeons)) have been disclosed. As one of the conventional biological exclusion devices, a device that includes an electroacoustic transducer (speaker) that periodically changes signals in different ultrasonic bands and radiates them in the air is disclosed. . In the following description, “exclusion” includes “disinfection”, “aversion”, and “avoidance”.

  As such, “a plurality of ultrasonic transmitters each having a different frequency band and a drive circuit for driving each ultrasonic transmitter are provided, and one of a plurality of predetermined drive modes is selected. And selecting a drive mode, and controlling the drive circuit based on the drive mode, and each mode includes at least one ultrasonic transmitter from the plurality of ultrasonic transmitters. A harmful animal extermination device using ultrasonic waves, characterized in that a random band that randomly selects and randomly controls the drive frequency and drive time of the drive circuit has been proposed (for example, Patent Document 1).

  In the harmful animal extermination device described in Patent Document 1, an ultrasonic signal is radiated to a storage device such as an IC mounted on a product equipped with a radiator according to a preprogrammed time and period. Therefore, signal processing is performed to prevent the object to which sound radiation is applied from getting used to the sound.

  In addition, as an example of harmful animals, “birds” can be cited as ones that are frequently excluded from various industries. In recent years, crows, starlings, and pigeons have been targeted as “birds”. Of these, it is well known that crows have the highest intelligence among "birds", and specialized research results show that crows are also good at communication between birds.

  In the conventional biological exclusion device, the crow's voice is emitted from the speaker at a high sound pressure level by directly emitting the crow's voice to the crow. There was also a thing (for example, refer patent document 2).

Japanese Patent Laid-Open No. 7-107893 (for example, pages 2 and 3) Japanese Patent No. 5135507 (for example, Example 1)

Since there are many animals that can be heard up to the frequency of the ultrasonic band, in the technique described in Patent Document 1, for animals that have the ability to hear the ultrasonic band among the organisms to be excluded, The effect of a certain period can be exhibited.
However, there are problems such as not using the ultrasonic band and not having a great influence on the organisms to be excluded such as crows having relatively high communication. In other words, the crow has an audible frequency band that is substantially equivalent to that of a human being, and has a low hearing ability with respect to the frequency of the ultrasonic band, and as a result, does not hear the ultrasonic wave (not heard). For this reason, there is a case where the elimination effect cannot be obtained at all by simply applying the frequency in the ultrasonic band to the crow.

In addition, even if the oscillation frequency of the ultrasonic signal is changed, it does not change that it changes at a constant rhythm, so that a certain amount of time gives the organisms to be excluded a “habituation” to the sound itself. In other words, there was a problem that the effect disappeared at an early stage.
For this reason, the technique described in Patent Document 1 cannot reliably exclude the organism to be excluded.

  In the technique described in Patent Document 2, it is important to make an elimination target organism hear an acoustic signal necessary for exclusion or the like. Therefore, it is necessary to radiate an acoustic signal at a sound pressure level equal to or higher than the sound of the organism to be excluded. For this reason, sound having a sound pressure level equal to or higher than the sound of the organism to be excluded is radiated at a high volume from a speaker for emitting sound regardless of the night. Therefore, since the sound signal necessary for the exclusion of the organisms to be excluded is emitted around the environment where the organism exclusion device is installed, it is equally given to the surrounding residents, and the "noise" caused by the installation environment Was causing the problem.

  Embodiments of the present invention will be described below with reference to the drawings. In addition, in the following drawings including FIG. 1, the relationship of the size of each component may be different from the actual one. Further, in the following drawings including FIG. 1, the same reference numerals denote the same or equivalent parts, and this is common throughout the entire specification. Furthermore, the forms of the constituent elements shown in the entire specification are merely examples, and are not limited to these descriptions.

Embodiment 1 FIG.
FIG. 1 is a basic block conceptual diagram showing a basic configuration of a biological exclusion apparatus 1A according to Embodiment 1 of the present invention. Hereinafter, the biological exclusion apparatus 1A will be described with reference to FIG. The organism exclusion device 1A is configured to give “light” to the organism to be excluded as a sound superimposed on the ultrasonic wave and as a means other than the audio. In the following description, “grant” includes “give”, “present”, and “exposure”.

The organism exclusion apparatus 1A includes at least an audio transmission unit 60 and a light emitting unit 70.
The sound transmission means 60 transmits from a sound radiation means (reproducing means 40) capable of oscillating a single ultrasonic frequency, to an amplitude-modulated or frequency-modulated ultrasonic band signal having a predetermined frequency width (for example, 40 kHz ± 2 kHz).
The light emitting means 70 is configured to give “light” as the giving means other than the sound.

<Audio transmission means 60>
The audio transmission unit 60 includes an ultrasonic signal creation unit 10, an exclusion signal unit 12, a processing circuit unit 25, an addition unit 30, a control unit 50, an amplifier 35, and a reproduction unit 40.
The amplifier 35 is not an essential configuration.
In addition, without adding the ultrasonic signal creation unit 10 to the addition unit 30, the signal from the exclusion signal unit can be transmitted to the control unit 50 as it is, and a configuration that can perform software signal processing is also provided. As a result, it is possible to output only the sound necessary for exclusion without being superposed on the ultrasonic signal, and it is possible to eliminate even with the conventional speaker means (speaker 130 shown in FIG. 1) without using special reproduction means. It is possible to reproduce / radiate the sound necessary for the recording.

  The ultrasonic signal creation unit 10 functions as a transmission circuit unit that creates a signal in an ultrasonic band of 43 kHz or higher. The signal frequency created by the ultrasonic signal creation unit 10 is used as a carrier signal.

The exclusion signal unit 12 is configured as an aggregate of the transmission circuit unit A20 and the transmission circuit unit B22.
In the transmission circuit unit A20, a raw original voice signal of the organism to be excluded (audio signal for the organism to be excluded) is stored, and a sound corresponding to the organism to be excluded is input.
The transmission circuit unit B22 uses white noise based on the sound signal for the organism to be excluded stored in the transmission circuit unit A20, and the original sound of the organism to be excluded, which is characteristic of the live sound, and the characteristic of the original sound. This is a storage area portion of pseudo sound (pseudo sound signal) created so as to be reproduced using acoustic characteristics.

  The processing circuit unit 25 creates a frequency characteristic of a voice pattern (first voice pattern) that promotes typical exclusion and a frequency characteristic of a plurality of pseudo voice patterns (second voice pattern) that are excluded from warning. By saving, random combination output with live audio is output at random. That is, the processing circuit unit 25 selects a second voice pattern to be combined with the first voice pattern, automatically performs a combination process on the selected second voice pattern and the first voice pattern, and outputs a random output. Yes.

  The adder 30 functions as a part that couples the sound of the rejection signal unit 12 and the ultrasonic signal generator 10, and amplitude-modulates or frequency-modulates the signals output from each to give a predetermined frequency width. The signal is an ultrasonic band signal (for example, 40 kHz ± 2 kHz).

The control unit 50 includes at least a CPU unit 51, a provision function control unit 52, and a speaker drive function control unit 53.
The CPU unit 51 has a function of controlling the operations of the reproducing unit 40 and the light emitting unit 70 based on the signal created by the adding unit 30.
The assignment function control unit 52 has a function of providing the CPU unit 51 with information for controlling the operation of the light emitting unit 70. The assignment function control means 52 stores information on the timing (time and time) of light emission and the light emission frequency in advance. These pieces of information are preferably rewritable.
The speaker drive function control unit 53 has a function of providing the CPU unit 51 with information for controlling the operation of the playback unit 40. The speaker drive function control means 53 stores in advance information related to the sound reproduction time (including the disclosure time and start time) and the peak value of the sound. These pieces of information are preferably rewritable.

The amplifier 35 amplifies the sound pressure level of the signal amplitude-modulated by the adding unit 30.
The reproduction means 40 reproduces the signal amplified by the amplifier 35 as sound or the like and transmits it to a remote place. The reproducing means 40 can oscillate a single ultrasonic frequency (for example, 40 kHz). Note that it is desirable that the reproducing means 40 emit a high sound pressure level in order to perform the same function as a known parametric speaker.

<Light emitting means 70>
The light emitting means 70 includes a light emitting source.
The luminescence source may be selected according to the organism to be excluded. As the light source, for example, a lamp, an LED that emits ultraviolet light, a blue LED, an LED that emits white or red light, or the like can be used.

[Exclusion of organisms to be excluded]
<Exclusion by voice>
Here, a case where a crow as an organism to be excluded is excluded using sound will be described.
In the case of animals that use voice communication or animals that perform collective behavior, it is known that voice communication is used to guide friends.
A crow has a developed brain and a vocal organ, and is known to perform high-level voice communication between friends using a plurality of calls. In addition, crows are roughly classified into two types of crows and crows, and the frequency bands of the voices used by each are different.

FIG. 2 is an explanatory diagram for explaining examples of time waveforms of voices of two types of crows, and is an example of analysis of a cry generated when a crow contends with a raptor. FIG. 2A shows an example of a time waveform of a voice of a crow crow, and FIG. 2B shows an example of a time waveform of a voice of a crow crow. In FIG. 2, the vertical axis represents frequency (kHz) and the horizontal axis represents time (SEC). The characteristics shown in FIG. 2 are merely examples of two types of crow sounds, and have several tens of types of frequency characteristics depending on the action content of the crow.
As shown in FIG. 2, the sound pressure level tends to be high in the Hashiboso crow band in the 1 kHz to 7 kHz band and the Hashibuto crow band in the 0.5 kHz to 6 kHz band.

  From FIG. 2, it can be seen that the frequency band output as speech differs depending on the type of crow.

In the biological exclusion device 1A, the crow's original sound, which is assumed to be an organism to be excluded, is either (single unit) or any combination of voices emitted during "fighting with raptors" and "during fear (disease)" The voice pattern that is emitted at the time of use is used. From FIG. 2, it can be seen that the frequency band of the generated voice is different depending on the type of crow. Therefore, by using “live” speech based on these speech patterns, the meaning of the speech is certain for the crow, and by using this speech, it is possible to surely perform the behavior of eliminating the crow.
In an actual environment, two types of crows may be mixed. Therefore, in the biological exclusion apparatus 1A, if both types of “live” audio are stored and randomly reproduced at appropriate time intervals, the effect can be exerted on both types.

  Figure 2 is a recording of the cry that crows make when fighting against the natural enemy, the raptor. When such a sound is played toward a group of crows, the crow rubs a cocoon on the tree, turns around the sky, and so on. When creating such a situation, it is possible to urge escape of the crow by irradiating the group of crows with “light” or “air pressure (described in the second embodiment)”.

  FIG. 3 is an explanatory diagram for explaining a pseudo sound example of a cry generated when a crow contends with a bird of prey. FIG. 3A is an example of a pseudo-voice of a crow crow, and FIG. 3B is an example of a pseudo-voice of a crow crow. In FIG. 3, the vertical axis represents frequency (kHz) and the horizontal axis represents time (SEC).

When the voice characteristic of FIG. 2 is analyzed, a characteristic frequency is extracted, and voice is created according to the type of crow, the result is as follows.
That is, the sound reproduced toward the crow may be an artificial sound having the characteristics in addition to the cry generated when the crow contends with the raptor.

<In the case of pseudo-voice when competing with a raptor of a sand-crowned crow>
One band is composed of 800 Hz to 1.5 kHz, 2.2 kHz to 3.8 kHz, 5.5 kHz to 6.2 kHz as one voice reproduction width, and one voice reproduction time width as 0.05 seconds.
The silence range between the bands is 0.01 seconds, and the band is reproduced four times and within 0.2 seconds.

<In the case of pseudo-voice when competing with a crow raptor>
One band is composed of 400 Hz to 1.8 kHz and 2.2 kHz to 3.0 kHz as one voice reproduction width and one voice reproduction time width as 0.05 seconds.
The silence range between the bands is 0.01 seconds, and the band is reproduced four times and within 0.2 seconds.

The crying voices of the Raven and Raven raptors are non-repetitive voices that are mixed with noise, but the same voices with different frequencies and accents are emitted at intervals of about 0.5-5 seconds. Have.
The pseudo sound shown in FIG. 3 is created by analyzing the sound of the original crow. Compared with the original sound, the case where the sound pressure level is higher in the relatively low frequency band is the seed of the mustard crow and the higher frequency band. It is the seeds of the Hashiboso crow that are playing up to 2 and the voices of the two crows are played in different frequency bands.

  In the case of a crow or the like having an advanced voice pattern, since there are a plurality of voice patterns for performing the avoidance action, it is difficult to create and save all the voices. Therefore, the biological exclusion apparatus 1A solves the problem of “familiarity” by creating and storing a plurality of pseudo sounds using the original sound.

As described above, the biological exclusion apparatus 1A uses the processing circuit unit 25 to perform the frequency characteristic of the voice pattern (first voice pattern) when competing with a typical bird of prey, and the pseudo voice pattern (the first voice pattern) that performs warning or the like. (2 voice patterns) and the free combination output of the live voice can be randomly output.
Note that in the biological exclusion device 1A, the maximum length of each voice pattern stored in the transmitting circuit unit A20 and the transmitting circuit unit B22 is 5 seconds or less, and the familiarity of the sound by letting it sound for a long time. It also prevents.

In addition, as shown in FIG. 2, in the frequency characteristic of the sound in the case of a crow, the part where the sound pressure is high is a middle band from 500 Hz to 3 kHz, and is included in the human audible frequency band. It is a recognizable level.
Therefore, if the crow voice pattern shown in the example is simply reproduced, it will be heard by humans.
Moreover, the sound pressure level of the crow's voice (scream) in nature is, for example, 70 dB to 80 dB even when the distance between the crow and the measuring instrument is 10 m, and has a very high sound pressure level. Yes.

  The output level (voice level) of the voice pattern of the exclusion signal unit 12 also needs to be radiated at a sound pressure level equal to or higher than that of the voice that actually generates crows in order to perform reliable avoidance action.

Therefore, the biological exclusion apparatus 1A superimposes a sound in an ultrasonic band by a modulated wave having a predetermined frequency width on a single ultrasonic frequency.
The sound pressure level that can be radiated by the reproducing means 40 is at least 124 dB at the time of measurement in proximity.

A single ultrasonic signal radiated from the reproducing means 40 that can radiate as a strong sound pressure level and a modulated ultrasonic signal are spatially propagated as a non-linear signal waveform under the influence of fluctuation due to friction with air. .
Therefore, unlike an acoustic signal that linearly propagates in space, a linear sound pressure level attenuation characteristic cannot be obtained, the sound pressure level is hardly attenuated, and is not affected by air pressure. The ultrasonic signal can be propagated linearly on the top.

The waveform of the ultrasonic signal that travels nonlinearly in the space can stop the propagation in the air when it collides with something. For this reason, a sum difference of the modulated ultrasonic waveforms is generated at the location of the collision, and sound in a frequency band having a width of (40 kHz ± 3 kHz) −40 kHz = 3 kHz is generated (demodulated) at the collision point.
As a result, no sound can be heard while propagating in space.

The reason why the modulation band is set to 3 kHz is that the crow's voice band extends to 3 kHz, and the crow's voice needs to be reliably reproduced, so that the 3 kHz modulation band is aimed.
In addition, the sound pressure level of the transmitted ultrasonic wave is 100 dB or more, and the audibility as a sound cannot be obtained, but the sensation as the pressure sensation can be imparted to the crow. For this reason, it is possible to impart a sense that cannot be obtained in nature to the crow.

As a reproduction system using ultrasonic waves as a carrier signal, there is a parametric speaker means, which is also known. Known parametric loudspeakers are aimed at providing noise-free sound for human subjects. For this reason, known parametric loudspeakers are reproduced by solving the problem of amplitude modulation by digital signal processing.
In the biological exclusion apparatus 1A, reproduction is performed together with a crow voice by utilizing the problem of amplitude modulation.
The problem is pulse noise caused by external noise.

  In amplitude modulation, a beat phenomenon occurs at the time of demodulation, and there are cases where two signals of ultrasonic and voice are generated “in a beat”. When sound and two ultrasonic waves generated as “beat” are reproduced from the reproduction means 40 and collide with a transmission destination crow, the sound is demodulated and the sound portion is given to the crow. In addition to voice, ultrasound with a high sound pressure level, which will be described later, will also be applied, so for crows, ultrasound that has never been bathed in nature other than audible speech that has been bathed in nature. A high sound pressure level is also given.

It is well known that ultrasound with a high sound pressure level is also used in medicine, and feels as a physical vibration. In other words, ultrasonic waves with high sound pressure levels have an unpleasant effect on crows by receiving ultrasonic pressure fluctuations that crows have never experienced, in addition to voices that urge crows to eliminate. Become.
Further, the pulse-like noise due to the external noise is directly given to the crow as an impact signal having a high sound pressure level.

  In addition, although the sound at the time of the battle with the crow's raptor has been described by adding the signal with the ultrasonic signal generating unit 10 and reproducing, as shown in FIG. 1, without adding the ultrasonic signal, A configuration may be adopted in which software signal processing can be performed in which the signal from the exclusion signal unit can be transmitted to the control unit 50 as it is. In this way, it is possible to output only the sound necessary for exclusion without being superimposed on the ultrasonic signal, and even without using special reproduction means, the conventional speaker means (speaker 130 shown in FIG. 1) The sound necessary for exclusion can be reproduced / radiated. This means that if there are no human beings in the surroundings that need to be excluded, the voice will be heard without undue caution against crows gathered in remote power facilities such as Noyama and related facilities. Since it may be possible to radiate, reproduction according to such a situation shall be possible.

<Exclusion by light emission>
Here, a case where a crow as an organism to be excluded is excluded using non-stationary (random) light emission will be described.
Unlike humans, crows are known to be able to recognize wavelengths in the ultraviolet band.
Therefore, the biological exclusion device 1A uses the visual characteristics of the crow to give the crow light emission irregularly or discontinuously regardless of day or night.

Since crows can see ultraviolet rays, LEDs that emit ultraviolet rays and blue LEDs are effective as the light source used for the light emitting means 70. If these are used, since a wavelength different from that of sunlight can be emitted, it can be effectively applied to the crow even in the daytime. For example, the light imparted to the crow may be light including a wavelength of 300 nm to 500 nm that is considered to be highly sensitive to the crow.
For birds and animals other than crows, white or red LEDs may be used as the light source of the light emitting means 70. Moreover, it becomes possible to cope with a large number of harmful birds and beasts by using an LED whose emission frequency can be varied.
By using light, it effectively acts on an organism to be excluded that is inferior to voice communication, such as pigeons and squirrels.

  FIG. 4 is an explanatory diagram for explaining an example of a timing pattern of light emission provided by the organism exclusion apparatus 1A. Based on FIG. 4, an example of a timing pattern for providing light emission will be described.

In the biological exclusion apparatus 1A, the light emitting means 70 emits light unsteadily. In other words, the organism exclusion device 1A is based on changing the light emission time and the stop time randomly in consideration of “threat” to the organisms to be excluded such as crows and other harmful birds and beasts.
Light emission includes single light emission and continuous light emission, light emission time includes predetermined light emission times B1, D1, and F1, and application time includes predetermined time intervals A1, C1, and E1.

First, the biological exclusion apparatus 1A does not emit light from the light emitting means 70 during the predetermined time interval A1.
Then, when the predetermined time interval A1 has passed, the organism exclusion apparatus 1A uses the light emitting means 70 to emit light once in a predetermined light emission time B1.
Thereafter, the organism exclusion apparatus 1A does not emit any light from the light emitting means 70 during the predetermined time interval C1.
When the predetermined time interval C1 has passed, the organism exclusion apparatus 1A uses the light emitting means 70 to continuously emit light at a predetermined light emission time D1 and a predetermined light emission time F1 with a predetermined time interval E1.

In this way, by emitting light randomly, light can be emitted in an almost infinite state, and compared to steady light emission, it is possible to prevent “habituation” and the like, and it is possible to eliminate the target organisms with certainty. It becomes.
Note that the predetermined light emission times B1, D1, and F1 and the predetermined time intervals A1, C1, and E1 shown in FIG. 4 are arbitrary and may be appropriately determined. These may be repeated, but it is preferable to avoid simple repetition because it leads to generation of “habituation” and the like.

<Sound and light emission timing pattern>
FIG. 5 is an explanatory diagram for explaining an example of sound and light emission timing given from the biological exclusion device 1A. Based on FIG. 5, the audio | voice and light emission which are given toward the crow from 1 A of biological exclusion apparatuses are demonstrated.

  As shown in FIG. 5, in the organism exclusion apparatus 1 </ b> A, after the sound is imparted by the reproducing unit 40, the light emitting unit 70 may emit light by continuously emitting light.

  In providing sound by the reproduction means 40, an ultrasonic signal having a single frequency with a strong sound pressure level and an ultrasonic signal with a modulation of about ± 3 kHz are added, and the added signal is, for example, in the audible range. Audio with linear directivity is conveyed by superimposing audio for the purpose of excluding target organisms such as crows.

A pulsed signal sound is generated irregularly in the sound of the continuous signal and is exposed to animals such as crows. For this reason, it is provided as an unpleasant impulse sound for animals that perform advanced communication.
In addition, amplitude modulation can be done with a simple circuit configuration, so that the circuit can be molded at low cost, and when installed outdoors, etc., it has a powerful countermeasure structure, circuit configuration, and circuit for external noise required for digital circuits. There is no need for complicated circuit settings. Therefore, the biological exclusion apparatus 1A has a feature that adopts a configuration that does not require digital processing and has a large cost merit for the circuit.

  As described above, the reproducing means 40 needs to emit a high sound pressure level. This is because when a crow is excluded in a residential area or the like, a crow's voice is given to a resident in the residential area in a reproduction method using a general speaker. In that case, it is just “noise” for the person who heard the crow's voice.

Therefore, in order not to give an unpleasant feeling to human beings, the biological exclusion apparatus 1A is configured to give sound only to crows by ultrasonic conveyance.
However, a known general parametric speaker provides an “acoustic signal” only to a target location, and the parametric method has a characteristic that directivity is very narrow. Further, since the element structure for the parametric speaker is not dedicated, there is a disadvantage that the amplitude of a diaphragm or the like for emitting sound at a high sound pressure level cannot be created. For this reason, conventionally, the sound is provided only at a target location at a sound pressure level that can be heard by humans.

However, when targeting a crow that is an example of an organism to be excluded, the number of individuals gathering in the crow's “roost” or “food ground” is very large. Therefore, it is necessary to radiate sound in a wide range (wide range) and at a large sound pressure level.
In this case, it is advantageous to radiate sound with a general speaker for middle and low range where the directivity is expanded to some extent, but if a sound pressure level equal to or higher than the sound pressure level of crow pronunciation is radiated in a wide range, Naturally, since it is also given to humans, as described above, it will give humans unpleasantness as “noise”.

From the above, to the target location, that is, to the crows that are in a group at a distance, the sound necessary for exclusion is sent as high a sound pressure as an ultrasonic wave carrier, and as wide as possible ( It is important to be able to provide speech with a wide range of directivity.
Therefore, in the biological exclusion apparatus 1A, by arranging a plurality of units (reproducing means 40) that can perform voice conveyance close to each other, it is possible to configure a voice conveyance apparatus that has linear directivity and wide directivity.
In this way, the target voice can be sent to a distant place over a wide range, so the sound (voice) ) Is not given, and noise problems do not occur.
Further, if a plurality of reproducing means 40 are provided, it is possible to ensure a high sound pressure level.

  In other words, the biological exclusion device 1A uses an ultrasonic signal with a strong sound pressure level as a carrier signal, and superimposes a voice (live voice or artificial voice) signal necessary for eliminating birds and beasts on the ultrasonic signal. . And the radiation range of sound radiation is narrowed (narrow directivity) by amplitude-modulating or frequency-modulating the superimposed audio signal. In this way, sound can be emitted while maintaining a strong sound pressure level in an arbitrary direction. As a result, the living organism exclusion apparatus 1A can carry a sound signal necessary for exterminating the organism to be excluded over a long distance while suppressing the deterioration of the sound pressure level accompanying the propagation of the ultrasonic signal over the distance.

When the transport signal reaches the organism to be excluded at the transport destination, the modulation signal is demodulated, and an audio signal such as extermination can be directly applied to the organism to be excluded. Therefore, since an acoustic signal (sound) necessary for exclusion is not given other than the organism to be excluded, general facilities around the building where the organism to be excluded will not be affected by noise or the like. .
In addition, since the necessary frequency of sound and the like is conveyed by ultrasonic waves, it is not necessary to use, for example, a high-performance speaker device for reproducing frequencies other than ultrasonic waves, and the device configuration is performed at low cost. Can do.

  Furthermore, instead of providing sound emission directly to the organism to be excluded, it is given to the organism to be excluded by “demodulating” the sound superimposed on the ultrasonic wave. Therefore, the frequency band such as the audio signal of the organism to be excluded can also cope with several Hz to several hundred kHz or more.

In addition, in the organism exclusion device 1A, light emission is given to the organism to be excluded in addition to sound. For example, as shown in FIG. 5, it is preferable to emit light continuously after giving by voice.
Therefore, according to the biological exclusion device 1A, in addition to the exclusion effect by sound, the exclusion effect by light emission is exhibited.

Specifically, according to the organism exclusion apparatus 1A, a plurality of exclusion means that can have various influences can be given to the organism to be excluded by driving with a combination of sound and light emission. For this reason, it is possible to prevent “acquisition” or the like by a single granting means, and it is possible to reliably exclude the organisms to be excluded.
In addition, according to the organism exclusion apparatus 1A, in order to use sound propagation by ultrasonic conveyance, it can be directly given only to the organism to be excluded. Therefore, an acoustic signal (sound) necessary for exclusion is not given other than the organisms to be excluded, and noise or the like is not exerted on general facilities around the building where the organisms to be excluded fly.

  FIG. 6 is an explanatory diagram for explaining an example of the regeneration means 40 of the organism exclusion apparatus 1A. FIG. 7 is an explanatory diagram for explaining a combination of the aerial ultrasonic oscillator 41 of the regenerating unit 40 of the biological exclusion apparatus 1A. FIG. 8 is a schematic diagram illustrating an arrangement example of the aerial ultrasonic oscillator 41 of the regeneration unit 40 of the biological exclusion apparatus 1A. FIG. 9 is a schematic diagram showing an arrangement example of the aerial ultrasonic oscillator 41 of the regenerating unit 40 of the biological exclusion apparatus 1A. FIG. 10 is an explanatory diagram for explaining an ultrasonic signal radiated from the aerial ultrasonic oscillator 41 of the reproducing means 40 of the biological exclusion apparatus 1A. The reproducing means 40 will be described in detail based on FIGS. 6A is a side view showing a schematic configuration of the aerial ultrasonic oscillator 41, and FIG. 6B is a top view showing a schematic configuration of the aerial ultrasonic oscillator 41.

  As shown in FIG. 6A, in the single structure of the aerial ultrasonic oscillator 41, the basic components of the aerial ultrasonic oscillator 41 are the horn part 42, the PZT part 43 of the piezoelectric element, and the PZT. This is an electrode 45 for supplying a voltage to the pedestal 44 and the PZT unit 43. In the biological exclusion apparatus 1A, in order to emit sound at a high sound pressure level, the resonance frequency of the aerial ultrasonic oscillator 41 is around 40 kHz. In addition, a metal plate 46 that supplies power for providing a piezoelectric effect to the PZT portion 43 is attached to the surface of the PZT portion 43 (the surface on the horn portion 42 side).

  In the single structure of the aerial ultrasonic oscillator 41, there is a vibration mode in which maximum vibration occurs in the central portion of the PZT portion 43. At this time, when a piezoelectric element that resonates at 40 kHz is used as the PZT portion 43, the central portion of the PZT portion 43 has the largest amplitude, and the end portion of the PZT portion 43 hardly vibrates. The horn portion 42 is fixed to the central portion of the most vibrated PZT portion 43. With this structure, the input voltage to the aerial ultrasonic oscillator 41 can be increased, and the displacement amount of the natural vibration of the aerial ultrasonic oscillator 41 can be greatly oscillated.

  For fixing the horn portion 42, it is necessary to use an adhesive having high heat resistance and high moisture resistance and to be installed outdoors. For this reason, the horn part 42 is made of the PZT part 43 (metal plate 46) by using an adhesive material that can withstand direct sunlight and the like as heat resistance at 80 degrees or more and moisture resistance as 100% RH. ). The horn portion 42 can be fixed by spot welding, but in this case, the horn portion 42 needs to be fixed to the metal plate 46 so as not to generate bubbles.

By using ultrasonic waves, there is an advantage that the direction in which the sound travels is linear, and the sound is hardly diffused. On the other hand, for a group of organisms to be excluded, sound emission over a wide range is required.
For this purpose, as shown in FIG. 7, it is preferable to arrange a plurality of aerial ultrasonic oscillators 41 at intervals of one wavelength + 1/4 wavelength. By doing so, the phase of the traveling wave of the sound can be matched, and sound emission over a wide range can be performed.
Also, as shown in FIG. 8, a plurality of aerial ultrasonic oscillators 41 may be arranged vertically and horizontally on an interval of one wavelength + 1/4 wavelength.

  Further, as shown in FIG. 9, a bending plate 80 bent at a predetermined angle θ is used, and a plurality of aerial ultrasonic oscillators 41 are arranged on this bending plate 80 in consideration of an interval of one wavelength + 1/4 wavelength. If it arrange | positions, it will become possible to perform sound radiation to a still wider range (dashed line X shown in FIG. 9). Thereby, sound radiation having directivity characteristics as shown in FIG. 10 can be performed.

Embodiment 2. FIG.
FIG. 11 is a basic block conceptual diagram showing a basic configuration of a biological exclusion device 1B according to Embodiment 2 of the present invention. Hereinafter, the biological exclusion apparatus 1B will be described with reference to FIG. In the second embodiment, the difference from the first embodiment described above will be mainly described, and parts having the same functions as those in the first embodiment will be denoted by the same reference numerals and description thereof will be omitted. And

  The biological exclusion apparatus 1A according to the first embodiment is configured to impart “light” to the organism to be excluded as an imparting means other than sound. “Pressure” is applied as an application means other than sound. The configuration other than the “pressure” application of the biological exclusion device 1B is the same as the configuration of the biological exclusion device 1A according to the first embodiment.

The organism exclusion apparatus 1B includes at least an audio transmission unit 60 and a pressure applying unit (air cannon) 90.
The pressure applying unit 90 applies a “pressure wave” as an applying unit other than the sound. That is, pressure waves are applied by firing air.
The CPU unit 51 has a function of controlling the operations of the reproducing unit 40 and the pressure applying unit 90 based on the signal created by the adding unit 30.
The application function control unit 52 has a function of providing the CPU unit 51 with information for controlling the operation of the pressure application unit 90. The application function control means 52 stores information relating to the timing (time and time) of pressure application and the pressure intensity in advance. These pieces of information are preferably rewritable.

<Pressure applying means 90>
The pressure imparting means 90 imparts a gas such as air to a to-be-excluded organism existing in an arbitrary area (fluid conveyance space Y shown in FIG. 11) in a lump shape (vortex ring (ring shape)). The pressure applying unit 90 includes a driving device 100 and a signal generating device 95. The drive device 100 includes a vibration force generation unit, a vibration unit, and a cabinet 91 that houses them.

  The vibration part includes at least a vibration plate 90g, a frame 92, a large arc damper (second elastic member) 93, and a large arc edge (first elastic member) 94. The vibration force generator includes at least a yoke 90a, a center pole 90b, a magnet 90c, a plate 90d, a voice coil 90e, and a voice coil bobbin 90f. The voice coil bobbin 90f and the diaphragm 90g are connected via an adhesive layer 90h. Note that the vibration unit and the vibration force generation unit constitute a magnetic circuit unit 103.

  The yoke 90a is a plate-like member that constitutes the base of the vibration force generator. The center pole 90b is a columnar member molded at the center of the yoke 90a. The magnet 90c is fixed to the outer peripheral side of the center pole 90b via a predetermined gap. That is, the yoke 90a fixes the center pole 90b and the magnet 90c. Although the shape of the yoke 90a is not particularly limited, for example, a disk-shaped plate member or the like may be used. The magnet 90c is made of, for example, neodymium, samarium cobalt, ferrite, or alnico.

  The plate 90d is a plate-like member fixed to the upper surface of the magnet 90c. The voice coil 90e inputs a signal for driving the driving device 100. The voice coil bobbin 90f is a substantially cylindrical member, and the voice coil 90e is wound around the outer peripheral surface. The winding width of the voice coil 90e (the contact area of the voice coil bobbin 90f of the voice coil 90e) has an area that covers the outer peripheral surface of the voice coil bobbin 90f as much as possible. The voice coil bobbin 90f is attached to the center pole 90b, and performs electromagnetic drive with the magnet 90c by the input signal form and input voltage applied to the voice coil 90e, and the entire voice coil bobbin 90f vibrates.

  The diaphragm 90g is mounted on the end surface of the voice coil bobbin 90f (the end surface opposite to the mounting surface with the center pole 90b) via an adhesive layer 90h. The diaphragm 90g may be a flat plate type, a cone type or a dome type which is a general speaker, but a flat plate type made of resin, metal or the like having high rigidity is desirable as a means for conveying a lump of fluid described later. . Further, since the air in the pressurized space 106 may be high-temperature (100 ° C. or higher) steam, the vibration plate 90g is made of, for example, a heat-resistant polypropylene or an ABS material, and the surface of the base material is silica. It is good to constitute by coating with an erosion resistant material such as.

  The adhesive layer 90h has a viscosity for fixing the diaphragm 90g to a fixed position of the voice coil bobbin 90f. The frame 92 is a member having a substantially donut shape when seen in a plan view. The frame 92 includes a first fixing portion 92a, a second fixing portion 92b, and a tapered portion 92c that connects the first fixing portion 92a and the second fixing portion 92b. The first fixed portion 92 a is fixed to the fixed end 105. The second fixing portion 92b is fixed to the upper surface of the plate 90d. In addition, the 1st fixing | fixed part 92a, the 2nd fixing | fixed part 92b, and the taper part 92c which comprise the flame | frame 92 may be integrally formed, and may be joined by welding joining etc. as a different body, respectively. .

  The large arc damper 93 has a substantially donut shape when viewed from above, and has one end connected to the outer peripheral surface of the voice coil bobbin 90f and the other end connected to the upper surface of the plate 90d. It is a curved member. The large arc damper 93 serves to hold the voice coil bobbin 90f at an arbitrary position on the plate 90d and the frame 92. The large arc edge 94 has a substantially donut shape when viewed in plan, and has one end connected to the upper surface of the first fixing portion 92a of the frame 92 and the other end connected to the upper surface of the outer peripheral portion of the diaphragm 90g. Yes. The large arc edge 94 functions to hold the diaphragm 90g at an arbitrary position of the frame 92.

  In order to discharge the air mass from the pressurization space (corresponding to the pressurization space 106 described later), it is necessary to generate a strong pressure fluctuation inside the pressurization space, and the necessary conveyance distance and the strong pressure fluctuation are generated. Experimental verification has shown that it is necessary to vibrate the diaphragm at least 10 mm or more inside the pressurized space in order to obtain Accordingly, in the driving device 100, the large arc damper 93 and the large arc edge 94 each have a radius of 10 mm or more, and the diaphragm 90g and the voice coil bobbin 90f are brought into their respective stationary states by the action of the large arc damper 93 and the large arc edge 94. In comparison, vibration of 10 mm or more can be performed.

  Therefore, the large arc damper 93 and the large arc edge 94 are formed of a material having excellent elasticity such as synthetic rubber (for example, ethylene-propylene-diene rubber (EPDM)). As a result, the large arc damper 93 and the large arc edge 94 have appropriate elasticity, so that the large arc damper 93 and the large arc edge 94 are prevented from breaking even when the amplitude of the diaphragm 90g is increased. Synthetic rubber is excellent in wear resistance. Furthermore, synthetic rubber is excellent in erosion resistance (specifically, oil resistance, heat resistance, cold resistance, ozone resistance, weather resistance, acid resistance, alkali resistance, etc.). Therefore, even if the fluid has an erodible component, erosion can be suppressed.

  The cabinet 91 includes a rear space 107 that is formed with the diaphragm 90g as a boundary and in which the magnetic circuit unit 103 of the driving device 100 can be installed, and a pressurization space 106 for storing a fluid that is conveyed as a vortex ring. It is a substantially box-shaped member. Further, the fixed end 105 is formed so as to protrude toward the inside at the facing portion of the inner wall of the cabinet 91. The first fixing portion 92a of the frame 92 is fixed to the upper surface of the fixed end 105 by any means (for example, a screw or an adhesive). Note that the fixed end 105 may be configured by fitting a member separate from the cabinet 91 to the inner wall surface of the cabinet 91, or by fixing the member to the inner wall surface of the cabinet 91 with a screw or an adhesive. It may be configured.

  The pressurizing space 106 is a space formed on the front side of the diaphragm 90g (the side that is not the connection side of the voice coil bobbin 90f), and stores air to be conveyed in a necessary direction. The pressurized space 106 has a predetermined volume corresponding to the amount of air for conveying air as a vortex ring.

  On the other hand, the rear space 107 is a space formed on the rear surface side (the connection side of the voice coil bobbin 90f) of the diaphragm 90g, and functions as a housing space in which the magnetic circuit unit 103 is disposed. Therefore, the rear space 107 has a volume enough to provide the magnetic circuit unit 103. However, it is assumed that the pressurization space 106 and the rear space 107 are not in communication and have no air permeability. That is, the pressurizing space 106 and the rear space 107 are partitioned by the fixed end 105 and the frame 92, and there is no air connection.

  The cabinet 91 is formed with a carry-out port 110 having an arbitrary opening diameter that allows the outside and the pressurized space 106 to communicate with each other. Here, a state in which one carry-out port 110 is formed on the wall surface of the cabinet 91 at the position facing the vibration plate 90g (the wall surface on the right side in FIG. 11) is shown as an example. In addition, the number and formation position of the carry-out port 110 are not specifically limited. The opening shape of the carry-out port 110 is not particularly limited, but may be the same shape as the planar shape of the diaphragm 90g, for example, a circle.

  Further, the cabinet 91 is formed with an opening 120 having an arbitrary opening diameter that allows communication between the outside and the rear space 107. By forming the opening 120, the outside and the magnetic circuit unit 103 are communicated with each other, and the movement of the diaphragm 90g is not suppressed. That is, the opening 120 functions to allow the vibration transmitted from the diaphragm 90g to be transmitted to the rear space 107 side to escape to the outside of the cabinet 91. Here, an example is shown in which the opening 120 is formed on the wall surface of the lower mold in FIG. The opening shape of the opening 120 is not particularly limited, but may be, for example, circular. Needless to say, a vibration absorbing member that absorbs vibration may be provided on the inner wall surface of the rear space 107.

  The signal generating device 95 includes at least a drive signal processing unit 95a and an amplifier unit 95b. The drive signal processing unit 95a has a function of generating a signal for driving the voice coil 90e. The amplifier unit 95b is connected to the subsequent stage of the drive signal processing unit 95a, and has a function of amplifying the signal generated by the drive signal processing unit 95a. The drive signal processing unit 95a generates a signal waveform. The generated signal is transmitted to the voice coil 90e via the amplifier unit 95b. Thereby, a magnetic force is generated in the magnetic circuit unit 103, and the diaphragm 90g is driven by the magnetic force.

  The voice coil 90e is connected to the signal generator 95 via a signal line (not shown) so that a current corresponding to the drive signal transmitted from the signal generator 95 flows. In this manner, the voice coil 90e becomes an electromagnet, and the voice coil bobbin 90f wound around the voice coil 90e vibrates due to the force (magnetic force) obtained by interacting with the magnetic field generated by the magnet 90c. Is transmitted to the diaphragm 90g through the adhesive layer 90h. Thus, in the pressure applying means 90, the voice coil bobbin 90f vibrates by the voice coil 90e, and thereby the diaphragm 90g vibrates to form a vortex ring.

[Exclusion of organisms to be excluded]
<Exclusion by pressure>
As a means of learning as a phenomenon that does not exist in nature and is unpleasant for the organism to be excluded, the application of pressure waves can be mentioned.
Therefore, the biological exclusion apparatus 1B includes pressure applying means 90 using a speaker structure of electroacoustic conversion means so that gas (air) can be applied as a lump.
By using the pressure, it effectively acts on an organism to be excluded that is inferior to voice communication, such as pigeons and squirrels.

  FIG. 12 is an explanatory diagram for explaining an example of a timing pattern of pressure applied by the organism exclusion device 1B. Based on FIG. 12, an example of a timing pattern of pressure application will be described.

In the biological exclusion device 1B, the pressure is applied from the pressure applying means 90 in an unsteady manner. In other words, the organism exclusion device 1B is based on changing the pressure application time and the stop time randomly in consideration of “threat” to the organisms to be excluded such as crows and other harmful birds and beasts.
The pressure application includes single application and continuous application, and the application intervals include predetermined application intervals A2, B2, C2, and D2.
Further, the magnitude of the pressure application is represented by peak values E2 to H2 which are driving forces of the means for applying force to the air (that is, the diaphragm 90g).

The signal generator 95 drives the diaphragm 90g with an impulse-type one-wave signal in the plus voltage direction having an arbitrary time width.
The driving waveform of the diaphragm 90g is similar to the waveform of light emitted from the light emitting means 70 described in the first embodiment.

First, the organism exclusion apparatus 1B does not apply any pressure from the pressure applying unit 90 during the predetermined time interval A2.
Then, when the predetermined time interval A2 has passed, the biological exclusion device 1B applies pressure at a predetermined peak value E2 using the pressure applying means 90.
Thereafter, the organism exclusion device 1B does not emit any light from the pressure applying means 90 during the predetermined time interval B2.
When the predetermined time interval B2 has passed, the organism exclusion device 1B uses the pressure applying means 90 to continuously apply the pressure of the predetermined peak value F2 and the predetermined peak value G2 with a predetermined time interval C2.
Then, the biological exclusion apparatus 1B uses the pressure applying unit 90 to continuously apply the pressure of the predetermined peak value G2 and the predetermined peak value H2 with a predetermined time interval D2.

In this way, by applying pressure randomly, it is possible to apply pressure in an almost infinite state, and it is possible to prevent “habituation” etc. compared to applying pressure constantly and reliably exclude it. It becomes possible to eliminate organisms.
Note that the predetermined time intervals A2, B2, C2, and D2 and the predetermined peak values E2, F2, G2, and H2 shown in FIG. 12 are arbitrary and may be determined as appropriate. These may be repeated, but it is preferable to avoid simple repetition because it leads to generation of “habituation” and the like.

In addition, the dimension of the diaphragm 90g can be changed according to the physique dimension of the organism to be excluded.
Further, when applying a pressure wave, a transient sound is generated by inputting an impulse signal having a driving waveform from the diaphragm 90g. This is because an impact sound (explosive sound) is generated according to the natural frequency of the material by forming the material of the diaphragm 90g with a metal material such as aluminum. That is, for example, when the diaphragm 90g is made of a metal-based material such as aluminum, a sound that sounds like a cymbal of a musical instrument is generated from the diaphragm 90g.

Therefore, such impact sounds can be generated at the same time. For the organisms to be excluded, a single shocking sound and a pressure wave resulting from this are applied to the body of the organism to be excluded. Discomfort can be efficiently imparted to the target organism.
Of course, since the material of the diaphragm 90g can be changed in various ways, the diaphragm 90g can be made of a resin-based material when noise becomes a problem such as in urban areas. The diaphragm 90g may be configured with a honeycomb structure. By doing so, the natural frequency of the diaphragm 90g can be shifted to a low frequency, and mixed with the hustle and toe sound, which is generated as a low frequency sound that is difficult for humans to hear.

<Voice and pressure application timing pattern>
FIG. 13 is an explanatory diagram for explaining an example of the timing of sound and pressure applied from the organism exclusion device 1B. Based on FIG. 13, sound and pressure applied from the organism exclusion device 1 </ b> B toward the crow will be described.

As shown in FIG. 13, in the organism exclusion apparatus 1B, it is preferable that the sound application by the reproducing unit 40 and the pressure application by the pressure applying unit 90 are alternately and repeatedly applied.
Therefore, according to the biological exclusion apparatus 1B, in addition to the exclusion effect by sound, the exclusion effect by pressure is exhibited.

  Specifically, according to the organism exclusion apparatus 1B, a plurality of exclusion means that can have various influences can be imparted to the organism to be excluded by being driven by a combination of sound and pressure. For this reason, it is possible to prevent “acquisition” or the like by a single granting means, and it is possible to reliably exclude the organisms to be excluded.

Embodiment 3 FIG.
FIG. 14 is a basic block conceptual diagram showing a basic configuration of a biological exclusion device 1C according to Embodiment 3 of the present invention. Hereinafter, the biological exclusion apparatus 1C will be described with reference to FIG. In the third embodiment, the difference from the first and second embodiments will be mainly described, and the same reference numerals are given to the portions having the same functions as the first and second embodiments. Shall be omitted.

  In the biological exclusion device 1A according to the first embodiment, “voice” + “light emission” is given, and in the biological exclusion device 1B according to the second embodiment, “voice” + “pressure” is given. The organism exclusion device 1C is configured to apply “voice” + “luminescence” + “pressure” to the organism to be excluded.

That is, the biological exclusion apparatus 1C includes at least the sound transmission unit 60, the light emitting unit 70, and the pressure applying unit 90.
The configuration for “light emission” is the same as the configuration of the first embodiment, and the configuration for “pressure” is the same as the configuration of the second embodiment.

<Timing pattern of voice, light emission and pressure>
FIG. 15 is an explanatory diagram for explaining an example of the timing of sound, light emission, and pressure applied from the biological exclusion device 1C. Based on FIG. 15, sound and pressure applied from the organism exclusion device 1 </ b> C toward the crow will be described.

As shown in FIG. 15, in the biological exclusion apparatus 1 </ b> C, after applying sound by the reproducing unit 40 and applying pressure by the pressure applying unit 90 alternately and repeatedly, the light emitting unit 70 emits light continuously to emit light. It is good to give it.
Therefore, according to the biological exclusion apparatus 1C, in addition to the exclusion effect by sound, the exclusion effect by light emission and pressure is exhibited.

  Specifically, according to the organism exclusion apparatus 1C, a plurality of exclusion means that can have various influences can be given to the organism to be excluded by being driven by a combination of sound, light emission, and pressure. . For this reason, it is possible to prevent “acquisition” or the like by a single granting means, and it is possible to reliably exclude the organisms to be excluded.

Embodiment 4 FIG.
FIGS. 16-19 is explanatory drawing for demonstrating the example of installation of the biological exclusion apparatus which concerns on either of Embodiment 1-3. A specific installation example of the biological exclusion device according to any one of the first to third embodiments will be described with reference to FIGS. Here, a case where the biological exclusion device 1A according to Embodiment 1 is installed will be described as an example.

In FIG. 16, the example of installation of the biological exclusion apparatus 1A to the utility pole 150 is shown.
In places where there are steel towers and utility poles that carry power, etc., organisms to be excluded may stop at the steel towers and utility poles themselves, or the power lines themselves. For steel towers and utility poles, when the organisms to be excluded reach the breeding season, nests are created and power outage problems due to short-circuits often occur.

In order to deal with such a problem, as shown in FIG. 16, the biological exclusion device 1 </ b> A may be installed at the root of the utility pole 150 or in the middle of the utility pole 150. By doing so, it becomes possible to efficiently exclude the organism to be excluded from the utility pole 150. In addition, if the biological exclusion device 1A is installed at both ends such as between the power lines over which the utility poles 150 are connected, it is possible to eliminate the stop of the organism to be excluded from the electric wire.
When the organism exclusion device 1A is installed, as shown in FIG. 16, it is installed so that “sound” or the like can be given to a place where the organism to be excluded is supposed to stop.

In FIG. 17, the example of installation of the biological exclusion apparatus 1A to the building 160 is shown.
It is assumed that the organisms to be excluded gather at places away from humans, such as in the interior of a building 160 such as an outdoor house, warehouse, or station. Alternatively, it is assumed that the organisms to be excluded gather in the gap near the roof of the building 160.
In addition, there are cases where nets are used to protect railway users from droppings that fall from above on platforms in stations, etc., but from the viewpoint of maintenance such as wiring on the upper part, the nets are not spread all over. Absent.

In order to cope with such a problem, as shown in FIG. 17, when the organism exclusion devices 1 </ b> A are installed at places where it is assumed that the organisms to be excluded at the upper part of the building 160 gather, at arbitrary intervals. Good. By doing so, it becomes possible to efficiently exclude the organism to be excluded from the building 160.
When the organism exclusion device 1A is installed, as shown in FIG. 17, it is installed so that “voice” or the like can be given to a place where the organism to be excluded is supposed to stop.
It should be noted that light and pressure also work effectively on excluded organisms that are inferior to voice communication, such as pigeons and squirrels.

FIG. 18 shows an installation example of the biological exclusion device 1A on the utility pole 171 installed in the vicinity of the garbage storage place 170.
There is a problem that the garbage 173 is devastated by collecting the organisms to be excluded aiming at the garbage 172 coming out of ordinary houses or apartment houses.

In order to deal with such a problem, as shown in FIG. 18, the biological exclusion device 1 </ b> A may be installed in the upper part of the garbage storage place 170, that is, in the middle of the utility pole 171. For example, while the garbage 172 is placed, “sound” or the like may be radiated from the organism exclusion device 1A toward the garbage 173 by temporal control (for example, from 6 am to 9 am). .
By doing so, the “sound” necessary for exclusion is always output from the garbage 173. Since this “speech” poses a danger to the organism to be excluded, a sound is generated from the garbage 173, so that a fear such as a friend being caught occurs in the organism to be excluded, and the object to be excluded in the garbage storage 170. You can create a state where creatures do not gather.

In addition, by changing the force of pressure to be applied and the wavelength of light, it is possible to affect cats, hakubishin, deer, raccoon dogs, bears, etc., which are also found in recent cities.
18 shows an example in which the biological exclusion device 1A is installed on the utility pole 171. However, the present invention is not limited to this, and the biological exclusion device is provided at a position where “sound” or the like can be given to the garbage 173. What is necessary is just to install 1A.

FIG. 19 shows an installation example of the biological exclusion device 1 </ b> A on the aircraft 180 and the runway 181.
The aircraft 180 has a problem of bird strike in which an organism to be excluded such as a bird collides.

  In order to deal with such a problem, as shown in FIG. 19, it is preferable to install the biological exclusion device 1A on an aircraft 180 or a runway 181 of an airfield. By doing so, it is possible to cope with the bird strike problem. That is, if the biological exclusion device 1A is mounted on the aircraft 180, “voice” or the like can be given in advance from the aircraft 180, and if the biological exclusion device 1A is installed on the runway 181, “sound” is preliminarily provided from the runway 181. And the organisms to be excluded that are swarming in the vicinity of the runway 181 can be effectively excluded before the aircraft enters.

  The biological exclusion device 1A may be installed only on either the aircraft 180 or the runway 181 or on both sides. The organisms to be excluded can be more effectively excluded by installing them on both sides and appropriately adjusting the timing of application.

  Although the biological exclusion device 1A has been described as an example in the fourth embodiment, either the biological exclusion device 1B or the biological exclusion device 1C may be installed. Further, even when a plurality of devices are installed, it is not necessary that all of them are the organism exclusion device 1A, and any one of the organism exclusion device 1A, the organism exclusion device 1B, and the organism exclusion device 1C is used alone or in combination as appropriate. You may do it.

Further, in the fourth embodiment, there is no particular mention of the timing of giving “speech” or the like from the organism exclusion device 1A. However, it may be given all the time, or when the organism to be excluded is detected. Also good. In this case, it is necessary to separately provide an animal detection sensor using infrared rays, ultrasonic waves, visible light, or an imaging device such as a camera.
Furthermore, the grant start time, grant end time, or grant time interval may be determined in advance, and the grant timing may be controlled by time.
