For a second passerby detecting device capable of detecting a vermin, a third passerby detecting device capable of detecting a person approaching the passage from the protected area side, and a vermin approaching the passage. It is equipped with a repellent stimulus launcher that launches a repellent stimulus that the vermin dislikes and drives the vermin to the harmful beast habitat side.
The repellent stimulus launcher fires the repellent stimulus when a harmful beast is detected by the second passerby detection device, and when a human is detected by the first passerby detection device, and During the period from when the person is no longer detected until the reference time elapses, the repellent stimulus is not emitted regardless of the detection status of the second passerby detection device, and the third passerby detection device does not emit the repellent stimulus. A harmful beast that does not fire the repellent stimulus when a human is detected and until the reference time elapses after the human is not detected, regardless of the detection status of the second passerby detection device. It is an intrusion prevention system.

It is preferable that the repellent stimulus launching device is configured to launch the repellent stimulus in the vicinity of the passage port in a direction intersecting the inside / outside traffic road. Further, the second passerby detection device is provided so as to be able to determine whether the position of the harmful beast is near or far from the passage port, and the repellent stimulus launching device is a determination result of the second passerby detection device. In response to this, it is preferable that the closer the position of the harmful beast is to the passageway, the stronger the intensity of the repellent stimulus to be emitted.

The electric fence has facing portions having a predetermined length facing each other on both sides of the inner and outer traffic roads, and the space between the pair of ends of the facing portions located on the protected area side serves as the passage port. The second passerby detection device is installed so as to be able to detect the harmful beast that has entered between the facing portions, and the repellent stimulus launching device launches the repellent stimulus toward the harmful beast between the facing portions. It is preferable that the configuration is such that Further, the third passerby detection device is provided so as to be able to detect humans and vermin approaching the passageway from the protected area side, and the repellent stimulus launching device is provided by the third passerby detection device. The repellent stimulus when a human or vermin is detected, and from the time when the human or vermin is no longer detected until the reference time elapses, regardless of the detection status of the second passerby detection device. It is preferable that the configuration does not fire.

Communication means for sharing information on the detection status of the detection device with each other may be provided.

The pest intrusion prevention system of the present invention is a large system that protects a specific area or village including a plurality of fields by surrounding it with one electric fence, so that it is better than installing a plurality of small systems as in the conventional case. , The total cost can be significantly reduced. In addition, it is necessary to provide a passageway for passing inside and outside traffic roads in the middle of the electric fence, but since the gate device with a unique configuration is installed at the passageway, harmful beasts invade the protected area from the passageway. Pedestrians and cars can pass through the entrance smoothly. In addition, even if the gate device becomes inoperable due to a power outage, etc., the passageway will not be blocked by physical obstacles such as open / close doors, so pedestrians and automobiles can pass without hindrance. can.

It is a top view which shows the whole image of one Embodiment of the pest invasion prevention system of this invention. It is a perspective view which shows the appearance of the gate device which the harmful animal intrusion prevention system of this embodiment has. FIG. 2A is a plan view showing the configuration of the first to third passerby detection devices included in the gate device shown in FIG. 2, and FIG. 2B is a plan view showing the configuration of the repellent stimulus launching device. 2A and 2B are plan views showing a modified example of the facing portion of the electric fence shown in FIG. 2.

Hereinafter, an embodiment of the pest intrusion prevention system of the present invention will be described with reference to the drawings. The harmful beast intrusion prevention system 10 of this embodiment is a system installed to protect a village or the like in a mountain from harmful beasts such as wild boar. For example, the village shown in FIG. 1 is inside surrounded by the vermin habitat area YA where the vermin inhabit, and almost the entire area of the village including multiple fields T, housing J, living road SD, etc. becomes the protected area HA. .. In addition, an inside / outside traffic road ND connecting the inside and the outside of the protected area HA crosses this village. The internal / external traffic road ND is a road leading to other neighboring villages, and pedestrians, bicycles, and automobiles (two-wheeled and four-wheeled) pass through it.

The vermin intrusion prevention system 10 is provided with an electric fence 12 that separates the vermin habitat area YA and the protected area HA and prevents the vermin from invading the protected area HA. Then, in order to pass through the inside / outside traffic road ND, two passages in the middle of the electric fence 12 are opened to provide passages 14, and a gate device 16 is installed at each passage 14.

As shown in FIG. 2, the electric fence 12 is provided by erection of two bare electric wires 18 on a large number of columns and attaching electric shock means (not shown). When there are two bare wires 18, it is preferable to install them at heights of about 20 cm and about 40 cm. At this height, harmful animals such as wild boars cannot jump over or pass through, and when harmful animals come into contact with them, they can accurately give an electric shock. The number of bare wires 18 may be increased to 3 or more.

The electric fence 12 has facing portions 12a having a predetermined length facing each other on both sides of the inner / outer traffic road ND. Assuming that the pair of ends of the facing portion 12a on the vermin habitat area YA side is the first end portion 12b (1) and the pair of ends on the protected area HA side is the second end portion 12b (2), 2 The passageway 14 is between the two second end portions 12b (2).

The gate device 16 includes a first passerby detection device 20, a second passerby detection device 22, a third passerby detection device 24, a repellent stimulus launcher 26, and a photovoltaic power generation device 28.

The first passerby detection device 20 can detect a human (pedestrian, a person riding a bicycle, a person driving a car, etc.) approaching the passage 14 from the harmful beast habitat area YA side separately from the harmful beast. It is a device, and is provided by erection of a support column on the side of the inside / outside traffic road ND and attaching a non-contact type sensor 20a to this support column. The sensor 20a is, for example, a distance sensor that irradiates light in the horizontal direction so as to cross the inner and outer roads ND, receives the reflected light from the object, and detects a change in the distance to the object, and has a low profile. It is fixed at a height where pedestrians and automobiles can be detected without being able to detect harmful beasts.

The first passerby detection device 20 determines that "a human being has been detected" when the sensor 22a reacts, that is, when it detects a pedestrian, a bicycle, a person riding a bicycle, or a car driven by a person.

The second passerby detection device 22 is a device capable of detecting harmful beasts approaching the passage 14 from the harmful beast habitat area YA side (harmful beasts entering between the opposite portion 12a from the harmful beast habitat area YA side). Three columns are erected on the outside of the facing portion 12a, the non-contact sensor 22a (1) is installed on the first column, the non-contact 22a (2) is installed on the second column, and the third column is connected. It is provided by attaching each of the non-contact type sensors 22a (3). As shown in FIG. 3A, the sensor 22a (1) is located farthest from the passage 14, the sensor 22a (3) is closest to the passage 14, and the sensor 22a (2) is installed. ) Is the middle position. The sensors 22a (1), 22a (2), and 22a (3) are also distance sensors and the like similar to the above, and are fixed at a height at which low-profile vermin can be detected.

The second passerby detection device 22 "detects a vermin" when at least one of the sensors 22a (1), 22a (2), 22a (3) reacts, that is, when it detects a vermin. ". Also, when a vermin approaches the passageway 14, it always enters the facing portion 12a from the first end portion 12b (1) and proceeds in the direction of the second end portion 12b (2), so which of the three sensors It is possible to determine whether the position of the harmful beast is close to or far from the passage 14 depending on whether the vermin senses the object. Since the sensors 22a (1), 22a (2), and 22a (3) cannot distinguish between a harmful beast and a human, it is determined that "a harmful beast has been detected" even when a human is detected.

The third passerby detection device 24 is a device that can detect a person (pedestrian, a person riding a bicycle, a person driving a car, etc.) approaching the passageway 14 from the protected area HA side, and is a device for ND inside and outside the road. A column is erected on the side, and a non-contact sensor 24a is attached to the column. The sensor 24a is also a distance sensor or the like similar to the above, and is fixed at a height at which it cannot detect low-profile vermin and can detect pedestrians and automobiles.

The third passerby detection device 24 determines that "human beings have been detected" when the sensor 24a detects an object, that is, when it detects a pedestrian, a bicycle, a person riding a bicycle, or a car driven by a person. do.

The repellent stimulus launcher 26 fires a repellent stimulus that the harmful beast dislikes against the harmful beast (the harmful beast between the opposite portions 12a) approaching the passage 14 and drives the harmful beast to the harmful beast habitat area YA side. It is a device and is installed outside the facing portion 12a.

As shown in FIG. 3B, the repellent stimulus launcher 26 includes three launchers 26a (1), 26a (2), 26a (3) that launch different repellent stimuli. The launching portion 26a (1) is arranged between the sensor 22a (2) and the sensor 22a (3) at a position close to the sensor 22a (2), generates a light blinking signal S1 which is a repellent stimulus, and causes an internal / external traffic road. Fire across the ND. The launching portion 26a (2) is arranged between the sensor 22a (2) and the sensor 22a (3) at a position close to the sensor 22a (3), generates a sound signal S2 which is a repellent stimulus, and generates an internal / external traffic road ND. Fire across. The sound signal S2 is preferably emitted through a directional speaker such as a parametric speaker. The launching portion 26a (3) is arranged between the sensor 22a (3) and the passage port 14, and launches the jet liquid S3, which is a repellent stimulus, so as to cross the inside / outside passage road ND. For example, a conductive liquid to which a predetermined high voltage is applied may be used as the injection liquid S3 to give an electric shock to the vermin.

The repellent stimulus launcher 26 fires a repellent stimulus when the vermin is detected by the second passerby detection device 22. Then, the stronger the repellent stimulus to be fired, the stronger the position of the harmful beast is determined to be closer to the passage port 14. However, the repellent stimulus launching device 26 detects a second passerby when a human is detected by the first passerby detection device 20 and until the reference time elapses after the human is not detected. No repellent stimulus is fired regardless of the detection status of the device 22. Similarly, when a human is detected by the third passerby detection device 24, and during the period from when the human is not detected until the reference time elapses, the detection status of the second passerby detection device 22 remains. Does not fire repellent stimuli, regardless. The above reference time is set to be longer than the time required for a human to pass through the passage 14. The specific operation of the repellent stimulus launcher 26 will be described in detail later.

The photovoltaic power generation device 28 is a device for securing an operating power source for each device included in the gate device 16, and is installed on the side of the first passerby detection device 20 here, and each is connected by a cable (not shown). It is connected to the device.

Next, an example of the operation of the harmful animal intrusion prevention system 10 will be described. Assuming that there are no humans or vermin near the passage 14 and the gate device 16, the repellent stimulus launching device 26 of the gate device 16 does not fire the repellent stimulus in the initial state.

First, consider a case where a human (pedestrian, a person riding a bicycle, a person driving a car, etc.) approaches the passage 14 from the vermin habitat area YA side. In this case, the sensor 20a reacts first, and the first passerby detection device 20 determines that "a human being has been detected". After that, when the human advances further, the determination of the first passerby detection device 20 returns to "human is not detected", and this time, the sensor 22a (1), the sensor 22a (2), and the sensor 22a (3) are in order. After reacting, the second passerby detection device 22 determines that "a harmful beast has been detected".

However, the reason why the second passerby detection device 22 determines that "harmful beasts have been detected" is that the reference time has elapsed since the determination of the first passerby detection device 20 returns to "humans are not detected". The repellent stimulus launcher 26 does not fire the repellent stimulus because it is before. Therefore, a human can pass through the passage 14 and enter the protected area HA without receiving a repellent stimulus.

Next, consider a case where a human (pedestrian, a person riding a bicycle, a person driving a car, etc.) approaches the passage 14 from the protected area HA side. In this case, the sensor 24a reacts first, and the third passerby detection device 24 determines that "a human being has been detected". After that, when the human advances further, the determination of the third passerby detection device 24 returns to "human is not detected", and when the person passes through the passage 14 and enters the opposite portion 12a, this time, the sensor 22a (3) , Sensor 22a (2), Sensor 22a (1) react in order, and the second passerby detection device 22 determines that "a harmful beast has been detected".

However, the reason why the second passerby detection device 22 determines that "harmful beasts have been detected" is that the reference time has elapsed since the determination of the third passerby detection device 24 returns to "humans are not detected". The repellent stimulus launcher 26 does not fire the repellent stimulus because it is before. Therefore, humans can pass through the opposing portion 12a and enter the vermin habitat area YA without receiving a repellent stimulus.

Next, consider the case where the vermin approaches the passage 14 from the vermin habitat area YA side. In this case, since the sensor 20a does not react to the harmful beast, the harmful beast enters the facing portion 12a in a state where the determination of the first passerby detection device 20 is held to "human beings are not detected". Then, the sensor 22a (1), the sensor 22a (2), and the sensor 22a (3) react in order, and the second passerby detection device 22 determines that "a harmful beast has been detected".

When the first sensor 22a (1) reacts, the repellent stimulus launching device 26 emits a light blinking signal S1 from the launching unit 26a (1) to alert the harmful beast and slow down the invasion speed of the harmful beast. When the next sensor 22a (2) reacts, the blinking speed of the light blinking signal S1 is increased to warn more strongly, and the sound signal S2 is emitted from the launching unit 26a (2) to strongly threaten the harmful beast. .. Further, when the next sensor 22a (3) reacts, the repellent stimulus launching device 26 raises the volume of the sound signal S2 and further launches the jet liquid S3 from the launching unit 26a (3) to violently inflict harmful beasts. Intimidate. Therefore, the vermin cannot pass through the passage 14 and can be driven away to the vermin habitat area YA.

Since the repellent stimulus launching device 26 launches the repellent stimulus in the direction intersecting the inside and outside traffic road ND, if it is a vermin, it suddenly receives a strong repellent stimulus, which is very surprising. Therefore, a sufficient threatening effect can be obtained, and the vermin cannot easily get used to the repellent stimulus. Further, as the harmful beast approaches the passageway 14, the intensity of the repellent stimulus becomes stronger, so that the harmful beast cannot continue to endure this and almost certainly escapes.

Further, the electric fence 12 has a facing portion 12a having a predetermined length, and when a harmful beast tries to invade, the electric fence 12 always enters the facing portion 12a from the first end portion 12b (1) side and enters the second end portion 12b ( Another major feature is that it is configured to proceed in the direction of 2). Due to the presence of the facing portion 12a, the operation of "increasing the strength of the repellent stimulus as the harmful beast approaches the passage 14" can be performed as a simple operation such as the second passerby detection device 22 and the repellent stimulus launching device 26. It can be realized by the device.

As described above, the vermin intrusion prevention system 10 is a large system that protects a specific area or village including a plurality of fields by surrounding it with one electric fence 12, so that a small system as in the conventional system can be used. The total cost can be significantly reduced compared to installing multiple units. Further, there is a passage 14 for passing the inside / outside passage ND in the middle of the electric fence 12, but since the gate device 16 having a unique configuration is installed in the passage 14, harmful beasts are protected from the passage 14. Pedestrians and automobiles can smoothly pass through the passage 14 without being able to invade the HA. Further, even if the gate device 16 becomes inoperable due to a power failure or the like, the passageway 14 is not blocked by a physical obstacle such as an opening / closing door, so that pedestrians and automobiles can pass without hindrance. be able to.

The harmful animal intrusion prevention system of the present invention is not limited to the above embodiment. For example, the non-contact sensors 20a, 22a (1) to 22a (3), 24a of the passerby detection devices 20, 22, 24 are distance sensors, but for example, an infrared sensor, an ultrasonic sensor, or the like is used. However, the same effect can be obtained.

The above-mentioned second passerby detection device 22 is provided with three sensors 22a (1) to 22a (3), and is configured to be able to determine whether the position of the harmful beast is near or far from the passage 14 in three stages. However, the number of steps can be freely determined, and the number of sensors can be changed accordingly.

The third passerby detection device 24 described above can detect a human approaching the passage 14 from the protected area HA side, so that the sensor 24a cannot detect a low-profile harmful beast and detects a human or a vehicle. Although it is fixed at a height that can be detected, the height of the sensor 24a is set to a height that can detect low-profile harmful animals so that both humans and harmful animals approaching the passage 14 can be detected from the protected area HA side. You may change it. With this change, the third passerby detection device 24 detects the harmful beast that has strayed into the protected area HA, and the repellent stimulus launcher 26 does not fire the repellent stimulus, so that the harmful beast is a repellent stimulus. It is possible to return to the vermin habitat area YA through the passage 14 without receiving.

The above-mentioned repellent stimulus launching device 26 has three launching portions 26a (1) to 26a (3), and launches three types of repellent stimuli (light blinking signal S1, sound signal S2, jet liquid S3) that are different from each other. Although it is configured, the number of launchers and the type of repellent stimulus emitted by each launcher can be freely changed. For example, the number of launching units may be reduced to two, and both may be configured to emit the sound signal S2. Further, the repellent stimulus launching device 26 is configured to change the intensity of the repellent stimulus in three stages according to the position of the vermin, but the number of stages can be freely determined. Alternatively, the intensity of the repellent stimulus may not be changed and may be fixed at a very strong intensity.

The structure of the electric fence is not particularly limited, and in addition to the structure in which a plurality of bare electric wires are erected on the columns as in the electric fence 12, for example, a structure in which a wire mesh is stretched may be used. Further, in the electric fence 12 described above, as shown in FIG. 3A, the two first end portions 12b (1) of the facing portion 12a are open ends of the electric fence 12, but FIG. As shown in a), the layout may be changed so that the first end portion 12b (1) on one side and the second end portion 12b (2) on one side are the open ends of the electric fence 12 or the layout is changed to FIG. As shown in b), the layout may be changed so that the two second end portions 12b (2) are the open ends of the electric fence 12.

Further, the electric fence 12 is provided with the facing portion 12a in that the operation of "increasing the intensity of the repellent stimulus as the harmful beast approaches the passage 14" is performed by the second passerby detection device 22 (sensor 22a (sensor 22a). Since the main purpose is to realize with a simple device such as 1) to 22a (3)) and the repellent stimulus launching device 26 (launching unit 26a (1) to 26a (3)), the length of the facing portion 12a. Can be set freely as long as this purpose can be achieved. When the second passerby detecting means and the repellent stimulus launching device are configured differently from the above (for example, the second passerby detecting means analyzes the image data of the camera to detect the presence and position of the harmful beast. In this case, it is less necessary to provide the facing portion 12a, so that the facing portion 12a may be omitted.

In the above-mentioned harmful animal intrusion prevention system 10, since the width of the inside / outside traffic road ND is relatively narrow, one set of gate devices 16 (three passerby detection devices and one repellent stimulus launching device) is used on one side of the inside / outside traffic road ND. It is installed together in. However, if the width of the inner / outer road ND is wide, the detection capability of each sensor may be insufficient or the threatening effect of the repellent stimulus launcher 26 may be insufficient. It is preferable to install one set at a time. In this case, communication for sharing the detection status information of all the passerby detection devices 20, 22, and 24 with each repellent stimulus launching device 26 so that the two repellent stimulus launching devices 26 can operate in cooperation with each other. It is preferable to provide means. The photovoltaic power generation device 28 may be installed separately on both sides of the internal / external traffic road ND, but only one is installed on one side, and the gate device 16 installed on the opposite side is passed through a cable buried in the ground. It may be configured to supply power.

In addition, the protected area is not limited in size or shape as long as it can be partitioned by an electric fence. Therefore, the vermin intrusion prevention system of the present invention can be installed not only in mountain villages but also in various places and areas.
