Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pseudo-speech generation apparatus used in a bird damage countermeasure system for preventing birds and the like from approaching a GPS antenna facility installed outdoors. When birds approach a GPS antenna facility or the like, it is conceivable that the birds collide with the antenna and cause damage to the antenna facility, or radio interference due to nesting at the antenna facility. In addition, if birds use the antenna as a perch, the alignment of the antenna will be misaligned by itself.
The PS antenna may not be able to receive weak radio waves from satellites. Therefore, there is a need for a technique for keeping birds away from such facilities.

[0002]

2. Description of the Related Art Conventionally, as a measure for preventing birds from approaching an antenna facility or the like, for example, a scarecrow is used,
Methods such as raising balloons that imitate eyeballs and playing warning sounds such as the sound of gun firing were used. These methods generally surprise and drive birds away from the scene by giving them unfamiliar or unpleasant stimuli.

[0003]

By the way, the scarecrow, the balloon, and the warning sound as described above are new stimuli or unpleasant stimuli for birds, but do not themselves have any meaning for birds. Also,
Even if it is a novel stimulus at first, or a very unpleasant stimulus, if you continue to provide a monotonous stimulus for a long time,
Birds become accustomed to the stimulus and lose the effect of getting rid of them.

[0004] On the other hand, birds have a unique "song" for each type, and it is known that the birds communicate to some extent by the "song". Also, this "song" is slightly different for each habitat,
It is also known that there is a "song" that indicates a warning ("Ecology and Environment of Animals", Toshihide Kawachi, Yasuyuki Sakuraya, Kyoritsu Shuppan. "Introduction to Behavior Research", P. Martin, P. Bainson, Tokai University Press).

[0005] While the warning sound itself used in the past to combat bird harm is merely a stimulus that has no meaning for birds, the above-mentioned "song" is used between individuals belonging to each race. Because it is a language, the meaning of a "song" that indicates a warning does not change regardless of repetition. SUMMARY OF THE INVENTION It is an object of the present invention to provide a pseudo sound generation device capable of outputting a warning sound rich in change including a sound that is meaningful for an inhibition target.

[0020]

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 3 shows an embodiment of the pseudo-speech generating apparatus according to claim 1 to which the invention according to claim 4 is applied. In the pseudo sound generation device shown in FIG.
The voice collecting means 121 is equivalent to the voice collecting means 121 described above, and is configured to collect sound from the outside world and to provide the processed sound to the input voice processing unit 202 corresponding to the feature extracting means 122. The function of the voice information input means 111 described in item 1 is realized, and voice information representing the characteristics of bird sounds is input into the pseudo voice generation device.

The processing result obtained by the input voice processing unit 202 is input to a mixer 204 together with a warning voice (which will be described later) obtained from a warning voice generation unit 203. The audio output processing unit 20 forming the audio output means 113 described in 1
5 and a speaker 206.

In the input speech processing section 202 shown in FIG. 3, an analog-to-digital conversion (A / D) section 211
The input voice received via the filter 212 is sampled and converted into digital data, which is subjected to a fast Fourier transform process by a digital signal processor (DSP) 213. In the audio output processing unit 205, a digital signal processor (DS
P) 214 again performs a fast Fourier transform on the output of the mixer 204 to obtain a digital-analog (D / A)
5 and the digital-
The output of the analog converter 215 is transmitted to the speaker 206 via the filter 216.

FIG. 4 shows the bird song.
As shown in (a), it is known that the meaning of "warning" is transmitted by shifting a normal "song" to a higher frequency direction by a predetermined frequency band (6 kHz to 9 kHz) (""Animal Ecology and the Environment", Toshihide Kawachi, Yasuyuki Sakuraya, Kyoritsu Publishing Co., Ltd. "Introduction to Behavioral Research", P. Martin, P. Bainson Tokai University Press).

Therefore, the warning voice generation unit 203 determines the difference (6
(kHz.about.9 kHz) may be generated and transmitted to the mixer 204 as a warning voice. By inputting such a warning voice and the processing result obtained by the input voice processing unit 202 to the mixer 204, as shown in FIG. Song ”(in the figure,
A “song” (shown by a thin line in the figure) to which the meaning of the warning is added can be synthesized based on the thick solid line).

That is, the warning information adding unit 1 described in claim 1 is provided by the warning voice generating unit 203 and the mixer 204.
Twelve functions are realized. Here, birds memorize the singing voice of the parent bird as a template during their growth period, and have the characteristic of singing according to the template when becoming an adult bird and singing by themselves, and with this template, individual birds inhabit It is believed that the dialect and language equivalents of each region have been inherited.

That is, by applying the invention of claim 4 and recording the "songs" of birds inhabiting the area in the area, and adding a meaning of warning to them, the birds that are the object of inhibition are just added. This makes it possible to more effectively synthesize a voice spectrum corresponding to a "song" that conveys the meaning of a warning. The meaning of the “warning” conveyed by the “song” is meaningful information corresponding to a human language, and can be expected to be less likely to be weathered than a mere stimulus.

Therefore, the voice spectrum corresponding to the "song" is converted into a pseudo-alert voice by the voice output processing unit 205 and output through the speaker 206, and a stimulus having a meaning of warning is given to the birds, thereby providing a long stimulus. It is possible to prevent birds from accessing the facility over time.

On the other hand, even a simple stimulus that has no meaning for birds is considered to be difficult for the birds to get used to the stimulus given if the stimulus is given in a variety of ways. In addition, a method of generating a variety of stimuli may be effective. Next, a method of generating a sound that gives a stimulus rich in changes will be described.

FIG. 5 shows an embodiment of a pseudo-speech generation apparatus according to claim 2 to which the inventions of claims 6 to 8 are applied.
The pseudo-sound generating apparatus shown in FIG.
The stimulus sound held in 1 is changed by the articulation processing unit 222 and used for the processing of the sound output processing unit 205.

In FIG. 5, the randomizing control unit 2
The configuration 23 is, for example, configured to generate a random numerical value corresponding to each unit described later, and to transmit the generated numerical value corresponding to each unit as a random control instruction. The above-described stimulus voice holding unit 221 corresponds to the stimulus voice holding unit 125 described in claim 6, and is obtained by sampling, for example, an average warning voice of a bird to be inhibited as a stimulus voice. The speech described in claim 1, wherein the at least one speech spectrum is held, and any one of the speech spectra is transmitted to the articulation processing unit 222 in response to a random control instruction received from the randomization control unit 223. It is configured to fulfill the function of the information input means 111.

Further, the articulation processing unit 222 receives the speech spectrum from the stimulus speech holding unit 221 described above,
According to the random control instruction received from the randomization control unit 223, for example, within the audible range of birds (100 Hz to 100 kHz)
In z), the center frequency of the voice spectrum is changed. In FIG. 5, the amplification processing unit 2
25 amplifies the output of the audio output processing unit 205 by applying an amplification factor that fluctuates within a predetermined range according to the random control instruction received from the randomization control unit 223, and amplifies the output of the audio output processing unit 205 to the speaker 206 via the switch 226. It is configured to send out.

The switch 226 shown in FIG. 5 operates in accordance with an instruction from the switch control section 227,
The switch control unit 227 controls the intermittent operation of the switch 226 in response to the random control instruction received from the randomization control unit 223. The audio output period during which the pseudo audio is output and the audio stop period during which the output is stopped are varied within a predetermined range.

In this case, the stimulus voice holding unit 221 and the articulation processing unit 222 operate according to the random control instruction sent from the randomization control unit 223,
Since the function of the deformation means 114 described in claim 2 is realized, the basic stimulus voice can be selected at random, and the center frequency of the selected stimulus voice can be changed at random. It is possible to generate a false alarm sound.

Further, the amplification processing section 225 and the switch control section 227 respectively operate in response to the random control instruction sent from the randomization control section 223, whereby the volume control means 115 and the volume control means described in claim 7 are operated. 8 realizes the function of the output pattern control means 117 and randomly fluctuates the volume of the above-mentioned warning voice, and also fluctuates the voice output period and the voice stop period related to the output of the warning voice. So you can
The way of giving the false alarm sound can also be changed.

As described above, the variation of the various elements characterizing the pseudo-alarm sound and the variation of the various elements characterizing the method of outputting the pseudo-alarm sound are randomly combined to provide a very complicated and varied program. Since the pseudo warning sound can be generated and output, it is possible to prevent the birds from becoming accustomed to the stimulus, and to maintain the bird repelling effect of the pseudo warning sound semi-permanently.

As a matter of course, it is also possible to apply the above-described process of adding a random variation to a "song" to which a meaning of a warning is added. FIG. 6 shows another embodiment of the pseudo-speech generation device according to claim 2. The pseudo sound generation device shown in FIG. 6 replaces the stimulus sound holding unit 221 shown in FIG. 5 with the microphone 201 and the input sound processing unit 20 shown in FIG.
2. It comprises a warning voice generation unit 203 and a mixer 204,
The pseudo warning sound obtained by the mixer 204 is input to the sound processing unit 222.

In this case, the function of the voice information input means 111 described in claim 2 is performed by the microphone 201, the input voice processing unit 202, the alert voice generation unit 203, and the mixer 204, and the meaning of the warning is given. The pseudo-alert sound representing the added “song” can be randomly changed and output. Therefore, instead of losing the meaning of the warning for birds of the type corresponding to the collected "song", the variation of the "song" is increased as a whole,
It can stimulate the nature of birds trying to defend their territory from other types of birds.

Thus, the vicinity of the facility where the pseudo sound generation device is installed is made to look as if it is a territory of another bird, and an effect of repelling various kinds of birds can be expected. Also, as shown in FIG. 6, by randomly changing the method of outputting the pseudo-alert sound, it becomes possible to output the pseudo-alert sound in a very complicated pattern. It is possible to prevent the birds from being repelled by the quasi-warning sound and to maintain the birds' repelling effect semipermanently.

By the way, since it is considered that a plurality of kinds of birds inhabit in the vicinity of the antenna facility or the like, it is necessary for the pseudo sound generation device to exert a repelling effect on various kinds of birds.

Next, a method of collecting "songs" of various birds and using them as a source of pseudo-alert sound will be described.
FIG. 7 shows an embodiment of the pseudo-speech generation device according to claim 5. In the pseudo sound generation device illustrated in FIG. 7, the sound collection control unit 231 controls the microphone 201 and the input sound processing unit 202 illustrated in FIG. 3 to, for example, periodically collect external sounds. The collection processing unit 232 is configured to store the voice spectrum obtained by the input voice processing unit 202 in the voice storage unit 233 as needed.

In the collection processing unit 232, the matching processing unit 234 calculates the degree of coincidence between each of the voice spectra already stored in the voice storage unit 233 and the newly received voice spectrum. In accordance with the degree of coincidence, it is configured to determine whether or not a new voice spectrum corresponds to a different “song”. When the determination processing unit 235 receives the processing result indicating that the degree of coincidence is low for all the voice spectra stored in the voice storage unit 233, the determination processing unit 235 replaces the newly collected voice spectrum with the existing “song”. May be determined to correspond to a different “song”, and may be provided to the processing of the accumulation processing unit 236.

When the number of voice spectra stored in the voice storage unit 233 is less than n, the storage processing unit 236 adds a new voice spectrum to the existing voice spectrum next to the existing voice spectrum. If a number of voice spectra are stored, a new voice spectrum may be stored instead of the oldest voice spectrum. As described above, the sound collection control unit 231 receives the collected sound information via the microphone 201 and the input sound processing unit 202, and
The function of the voice storage unit 123 described in claim 5 can be realized by the collection processing unit 232 storing appropriate voice information in the voice storage unit 233.

This makes it possible to flexibly cope with the case where the type of birds inhabiting the facility changes due to factors such as the seasons, and to reliably store "songs" corresponding to the birds to be inhibited. can do. In FIG. 7, the selection control unit 237 corresponds to the collected voice selection unit 124 described in claim 5. For example, the selection control unit 237 stores the voice spectrum stored in the voice storage unit 233 at regular intervals. And selectively read out the corresponding audio spectrum via the read-out processing unit 238.
The configuration is such that it is provided for addition processing by the mixer 204.

In this way, a plurality of different “songs” are accumulated and subjected to the processing of generating a pseudo-alert sound, so that various kinds of birds inhabiting the area can be “warned”. Can be conveyed to the meaning of or the territory of other types of birds, so that repellent effects can be expected even in areas with diverse ecosystems.

Also, by randomly selecting any one of the plurality of "songs" stored in the voice storage unit 233, the pseudo warning voice can be used as a stimulus with various changes. It is possible to prevent the user from getting used to the voice and obtain the repellent effect over a long period of time. Also, as shown in FIG. 8, the stimulus voice holding unit 2 shown in FIG.
21 in response to an instruction from the selection control unit 237,
The reading processing unit 238 may be configured to selectively read out the voice spectrum stored in the stimulus voice storage unit 221 or the voice spectrum stored in the voice storage unit 233.

In this case, for example, the stimulus voice holding unit 22
First, if a voice spectrum corresponding to a standard “song” of a plurality of birds is held as a stimulus voice, a stimulus voice created in advance together with the collected voice can be used.
Further, it is possible to generate a pseudo-alert sound having a wide variety of variations. Next, "songs" with the meaning of a warning
A method will be described in which a pseudo-alert sound corresponding to the above is combined with a pseudo-alert sound obtained by randomly varying a stimulus voice.

FIG. 9 shows a third embodiment of the pseudo-speech generating apparatus. In FIG. 9, the pseudo sound generation device adds the articulation processing unit 222 and the randomization control unit 223 shown in FIG. 5 to the pseudo sound generation device shown in FIG. Accordingly, claim 3
The selector 241 corresponding to the selection means 115 described above has a configuration in which either the output of the mixer 204 or the output of the articulation processing unit 222 is selectively transmitted to the audio output processing unit 205.

In this case, a pseudo-alert sound that is rich in change is generated by randomly switching between a “song” that conveys the meaning of a warning to birds and a stimulus sound that is randomly varied. The information contained in the song itself can alert the birds to their alertness, and in some cases, they can stimulate the birds' territorial consciousness with pseudo-alert sounds. As a result, it is possible to exert the repelling effect on various kinds of birds, prevent the birds from becoming a stimulus of a pseudo warning sound, and maintain the repelling effect.

Incidentally, it is useless to output the pseudo warning sound as described above in a state where there are no birds nearby. Therefore, next, a method of effectively applying the pseudo warning sound only when birds are present in the vicinity will be described. FIG. 10 shows an embodiment of the pseudo-speech generating apparatus according to claim 10.

In the pseudo voice generating apparatus shown in FIG.
The power supply control unit 242 operates the alert sound generation unit 203, the mixer 204, the sound output processing unit 205, and the speaker 206 according to the sound information collected by the microphone 201 and the input sound processing unit 202 illustrated in FIG. Is configured to control the power supply for In the power supply control unit 242, the determination processing unit 243 determines whether or not the audio spectrum received from the input audio processing unit 202 is the sound emitted from birds, and outputs a switch signal indicating the determination result to the switch 244. To the power supply unit 2 by controlling the operation of the switch 244.
From 45, the power supply to each unit described above is started or stopped.

As described above, when the result of the determination by the determination processing unit 243 indicates that the sound uttered by the bird has been input, the switch 244 is closed to supply power from the power unit 245 to the above-described units. By doing so, the function of the output control means 135 described in claim 10 is realized, and it becomes possible to output a pseudo-alert sound in response to the approach of birds, and the pseudo-alert sound can be made to work effectively.

Further, in this case, when no birds are present in the vicinity, it is only necessary to supply power to the microphone 201 and the input voice processing unit 202. Therefore, the power consumption of the pseudo voice generator is reduced as a whole. be able to. Further, the microphone 201 and the input audio processing unit 202 shown in FIG. 10 are connected via another switch 246, and the switch 246 outputs the pseudo alarm sound from the audio output processing unit 205. Is received, and the input to the input voice processing unit 202 is cut off.

Thus, the voice output by the pseudo voice generating apparatus itself can be excluded from the determination target by the above-described determination processing unit 243, and only the voice of the birds flying nearby can be used as a trigger of the pseudo warning voice generation process. it can. By the way, it is generally known that birds mainly operate during the day, fly to roost trees in the evening, and rest in the roost at night. When an antenna facility or the like is used as a roost for birds, there is a concern that damage to the facility will be particularly large.

On the other hand, if it is possible to prevent birds from entering during the day, it is considered that there is almost no need to output a pseudo warning sound at night, and it is necessary to maintain a function for generating a pseudo voice at night. Is useless.

Next, a method of effectively applying the pseudo warning sound in consideration of the above-mentioned habits of birds will be described. FIG. 11 shows an embodiment of the pseudo-speech generation device according to claim 9. In the pseudo sound generation device shown in FIG. 11, the power supply unit 251 corresponds to the power supply unit 134 described in claim 9, and shown in FIG. 3 in accordance with an instruction from the time management unit 252. A microphone 201, an input voice processing unit 202, a warning voice generation unit 203, a mixer 204,
The power supply for the operation of the audio output processing unit 205 and the speaker 206 is supplied.

In the time management section 252, the control signal generation section 253 corresponds to the determination section 133, and includes the current date and time obtained by the date and time measurement section 131 formed by the calendar 254 and the clock 255, and the condition information. Condition information storage unit 256 corresponding to storage unit 132
The control signal for controlling the operation of the power supply unit 251 is generated based on the information on the sunrise and sunset times in the area held in the power supply unit.

For example, the control signal generating section 253 refers to the condition information holding section 256 based on the date received from the calendar 254, holds the corresponding sunrise time and sunset time, and receives the time from the clock 255. When the current time reaches the time of sunrise, a control signal for supplying power to the power supply unit 251 may be transmitted and maintained.

Thereafter, when the current time received from the clock 255 becomes the time of sunset, the power supply unit 25
1, a control signal for stopping the supply of power may be transmitted and maintained. In this way, it is possible to supply power for operation to each part of the pseudo-sound generator at the time of day in the area,
When it is not necessary to operate the pseudo sound generation device, such as at night, power supply can be stopped to reduce overall power consumption.

Further, if the power supply is controlled in consideration of the time zone of twilight or dusk, it is possible to reduce the power consumption while completely covering the activity time of birds. When the pseudo sound generation device is installed in a GPS antenna facility, instead of providing an independent calendar 254 and a clock 255 inside the pseudo sound generation device, a GPS
What is necessary is just to receive accurately corrected date information and time information from the antenna facility, and to provide the control signal generation unit 253 with the processing.

On the other hand, it is also possible to combine the technique of controlling the power supply to the pseudo-sound generating apparatus in accordance with the bird's activity time with the technique of operating the pseudo-sound generating apparatus in response to the approach of the birds.
