Description

  The present invention relates to a bird and animal damage prevention apparatus that uses the sound of each animal that causes various damages by birds and beasts, exterminates and repels birds and animals, and prevents various damages caused by birds and animals without being killed.

There are cases where birds and animals are devastated before harvesting crops that are cultivated with great care, resulting in a reduction in the yield and product value, and a demand for damage reduction by birds that cause damage to the rooftops of apartment buildings.
While listening to the voices of the field, we conducted an experiment on the effects and announced the results for further damage reduction. The damage is spreading to general residential areas other than agricultural land. It is an urgent need to develop a device that will be effective in each usage environment, and we propose this as an aid.
In the past, verification of the effects of devices called bird extermination devices, beast repelling devices, etc., is quite difficult, whether it be light, sound, or reflective tape. The same applies to the use of voice. The words of extermination and repulse are ahead. In the original sense, this equipment has the significance of preventing the damage. The name is bird and animal damage prevention device.
Even if it is used only during the harvest season of the operating environment, the birds and beasts learn by playing audio throughout the year. It is necessary to change the voice regularly. The proposed apparatus can easily exchange voice devices.

The power generation efficiency has a slope that does not significantly decrease in any direction.

GPS is provided by cooperating manufacturers and depends on the basic package specifications.
Development of the integrated management map for the location management is narrowed down by region, prefecture, city, town, and installation area, and on a map where multiple fixed machines (birds and animals damage prevention devices) installed in each region can be grasped. Is displayed. The map shrinks and expands. This also extends the snooping area of the lost device. It is possible to manage all (multi-installed bird and animal damage prevention devices) on a map (on the map) of an integrated database (base unit) PC or mobile / tablet terminal.

In the future, communication devices will be installed in various fixed machines (birds and animals damage prevention devices). Considering data collection, the transfer of small numerical information and compressed image information will be an issue. The applicable interface may be a new communication technology for LPWA (low power wide area IoT). It is low-priced and can be divided and transferred even in poor communication environments that are suitable for collecting numerical information of devices in mountainous areas and areas where communication is difficult. Although the practical period will come first, there are many challenges to be fulfilled as a contribution to the developing society.
We think that this fixed machine (bird and beast damage prevention device) has the potential to grow as a cloud terminal in the future, and can easily collect spot information of regions and mountainous areas. I am convinced that the acquisition of image information, temperature, humidity, water level, sound and other information obtained from fixed sensors at the time of a disaster is always useful.

FIG. 5 shows a speech waveform of a crow's cry, FIG. 5 (A) shows a crow's normal sound, and FIG. 5 (B) shows a crow's warning sound. A normal sound is a utterance sound when preying on food, etc., and a warning sound is a voice when encountering a life crisis in living, a sound of a natural enemy when attacked by a natural enemy, a scream or pain at that time Say the sound.
In FIG. 5, time is shown on the horizontal axis, and amplitude (sound volume) is shown on the vertical axis. FIG. 5A shows a state in which the voice is uttered six times in 2.2 seconds. That is, in FIG. 5A, the waveform changes about 6 times in 2.2 seconds. Note that a section uttered once is referred to as “speech section H”.
On the other hand, FIG. 5B shows a state where the voice is uttered eight times in 5.6 seconds. That is, in FIG. 5B, the waveform changes eight times in 5.6 seconds.

FIG. 8 is a graph in which the horizontal axis of the speech waveform shown in FIG. 5 is combined. FIG. 8A shows a waveform that changes approximately six times in 2.2 seconds, and FIG. The wavelength changes 3 times in 2 seconds.
As shown in the speech waveforms of FIGS. 5 and 8, the length of the utterance interval is different between the normal sound and the warning sound. For example, the length of the normal sound utterance section (reference numeral H1 in FIG. 8A) is shorter than the length of the warning sound utterance section (reference numeral H2 in FIG. 8B). That is, the time of the normal sound is short, and the warning sound is long.
Further, the number of utterances per unit time is different between the normal sound and the warning sound. Specifically, the number of utterances of the normal sound is larger than the number of utterances of the warning sound. For example, in the example of FIG. 8, the normal sound is uttered 6 times in 2.2 seconds (FIG. 8A), and the warning sound is uttered 3 times in 2.2 seconds (FIG. 8B).

6A and 6B are diagrams illustrating an amplitude spectrum of a crow's cry. FIG. 6A illustrates a crow's normal sound, and FIG. 6B illustrates a crow's warning sound. In FIG. 6, time is plotted on the horizontal axis, frequency (pitch) is plotted on the vertical axis, and amplitude (sound volume) is shown by white shading.
That is, FIG. 6 (A) shows a crow's normal sound, and a ghost corresponding to the crow's cry in FIG. 5 (A) appears. FIG. 6B shows a crow warning sound, and a ghost corresponding to the crow bark of FIG. 5B appears.
As shown in FIG. 6, when the ghost of the normal sound and the warning sound are compared, a plurality of differences can be confirmed.
For example, the first difference is the presence or absence of a frequency change in one utterance interval. As shown in FIG. 6A, the frequency of the normal sound changes within the utterance section H1. That is, the frequency of the normal sound is low at the beginning of the utterance section H1, becomes high in the middle of the section H1, and further decreases at the end of the section H1.
On the other hand, as shown in FIG. 6B, the frequency of the warning sound does not change within the utterance section H2.
Next, the second difference is that the frequency is different.
For example, the maximum value P _A of the frequency in the vocal section of normal sound, when the maximum value P _B of the frequency in the vocal section vigilance sounds, since the maximum value PA is smaller than the maximum value P _B, the frequency of the normal sound is The frequency of the warning sound is lower. That is, when these ghosts are compared with each other, the warning sound includes a high tone (high frequency component) throughout a single utterance section with respect to the normal sound.
Further, as a third difference, there is a difference in the appearance of a spectrum ghost. For example, as shown in FIG. 6A, a frequency component with a ghost appears continuously from the beginning to the end of the utterance section in the normal sound. On the other hand, as shown in FIG. 6B, in the warning sound, a frequency component with a ghost appears sporadically in one utterance section.
In addition, as a common point, the point from which the magnitude | size of an amplitude for every frequency differs is mentioned.
For example, the normal sound shown in FIG. 6 (A) and the warning sound shown in FIG. 6 (B) are dark in the low frequency region, and thin in the high frequency region. In common. That is, the amplitude (sound volume) is large in the low frequency region, and the amplitude is small in the high frequency region.

FIG. 7 is a diagram (FFT) obtained by frequency analysis of the speech waveform shown in FIG. In FIG. 7, the horizontal axis represents frequency and the vertical axis represents amplitude. FIG. 7A shows a state of frequency analysis of the voice at time Ta in FIG. 5A, and FIG. 7B shows a state of frequency analysis of the voice at time Tb in FIG. 5B. .
As the frequency shows, it is analysis data extracted from a certain point.
A common point between FIG. 7A showing a normal sound and FIG. 7B showing a warning sound is that the change in amplitude is almost the same. For example, the amplitude ranges from a low frequency region to a critical region (frequency f) with a constant size and a constant width. On the other hand, it attenuates gently after the critical region.
On the other hand, as a difference, the difference in the density of the amplitude (a gap where the waveform changes) is well understood.
For example, the density is low in FIG. 7A and the density is high in FIG. 7B. Specifically, the number of times (4 times) the waveform changes within a certain frequency interval i in FIG. 7A is the number of times the waveform changes (8 times) within the certain frequency interval i in FIG. Less).
