Description

The present invention relates to a device for repelling relatively large wild vermin represented by wild boar.

In recent years, crop damage caused by large wild animals such as ino and deer has increased rapidly. It is effective to install fences and wire mesh on the farmland as a countermeasure, but the cost of introducing the fences and wire mesh is high, and maintenance and inspection of the fences and wire mesh are required, which takes a lot of time and effort. In addition, depending on the vermin, the effect was weakened by jumping over fences and wire mesh, digging holes and invading agricultural land. Furthermore, in the case of an electric fence, there are cases of accidents in which a person who approaches carelessly gets an electric shock. As a countermeasure, a more effective and safe repellent device for wild vermin is desired.

In the device of Patent Document 1, a device capable of irradiating for a long time from the evening to the next morning when a pest is active by a program timer or a brightness sensor is disclosed, but since it operates from the evening to the next morning, it is during the daytime. No effect is seen on the appearance in, and the area range where the effect is exerted is only the direction in which the device is installed, and there is no repulsion effect in all directions.

The apparatus of Patent Document 2 includes a light emitter having two or more light emitting elements of red, blue, yellow, and white, and blinking control means, and the luminous flux of each light emitting element is 80 lumens or more. The device is disclosed. The area range where this device is effective is only in the direction in which the device is installed, and there is no repulsion effect in all directions.

Further, in the device of Patent Document 3, an example of a rotation mechanism in which the light source unit can be rotated by a device having an infrared sensing sensor for detecting the approach of a vermin and a light source unit having an ultraviolet irradiation LED and a white light irradiation LED is clearly shown. ing. Therefore, the area range that exerts the repulsion effect is omnidirectional, but the equipment becomes complicated due to the rotation mechanism, and it is easy to install and carry, and the weight of the equipment itself becomes heavy, so that the equipment becomes expensive. There were problems such as failure of the rotating mechanism.

Further, the device of Patent Document 4 is a vermin repellent device including a light emitting device that is driven in a monitoring area and intermittently emits a flash with high brightness and a constant projection direction, and a rotating device that rotates the light emitting device. Disclosed is a device in which the rotating device comprises an annular guide rail provided in a monitoring area and a rotating traveling unit that moves along the guide rail. Therefore, although the area range that exerts the repelling effect is wide, the device becomes complicated due to the need for a rotating traveling part and a guide rail, and the handling and the device itself become expensive due to the heavy weight of the device itself. There are challenges.

In addition, infrared sensors are used for the detection of wild vermin in the repellent device, but due to the nature of most of them being pyroelectric elements, an unnecessary detection signal was occasionally output due to sudden noise output. .. In addition, even if there are no animals, light rays such as sunlight and reflected light are incident on the infrared sensor, and further, due to the fluctuation of trees, plants and leaves located between the infrared sensor and the sunlight and reflected light, etc. Unnecessary detection signals were generated due to environmental noise factors such as changes in infrared rays. Due to such sudden noise output and environmental noise, there was also a problem that the repellent device flashed and emitted due to an unnecessary detection signal that was generated even if there were no wild vermin.

In order to solve the above-mentioned problems, the installation cost and maintenance cost are low and it has a repellent effect regardless of daytime or nighttime. It enables the detection of harmful animals and blinking light emission, suppresses the maximum current of the power supply section of the device by the anti-phase generating means, and also has the suddenness of the infrared sensor by the false signal judging means. By preventing blinking light emission due to unnecessary detection signals generated by noise output and environmental noise, and using multiple high-brightness green LEDs or multiple green, red and blue LEDs, blinking light emission of wild beasts The purpose is to provide a repellent device that can prevent accustomed to and maintain the repellent effect.

The present invention aims to solve the above-mentioned problems, and has an infrared sensor for detecting wild beasts and a plurality of high-intensity green LEDs or a plurality of green and red on each side surface of the rectangular housing. It also has a light emitter with a blue LED, a power supply unit that supplies power to the light emitter, and a control unit and a drive unit that control the blinking interval of the light emitter and the duration of blinking. Further, the control unit includes an erroneous signal determination means, an anti-phase generation means, an energization time control means, and a day / night switching means.

Therefore, it is possible to blink and emit light according to the detection of wild pests by the infrared sensor regardless of day and night, and since it has an infrared sensor and a light emitter on each side of the rectangular shape, it can be used in all horizontal directions. It can be detected and blinks in the direction, and the area range that the repulsion effect exerts is possible in all directions. Further, since a plurality of high-luminance green LEDs or a plurality of green, red, and blue LEDs are arranged and blinking and emitting light, it is possible to maintain the repellent effect by glare.

Further, in the light emitters arranged on each side surface of the housing, the timing of blinking light emission of the two adjacent side light emitters or the two side light emitters located at positions in the 180 degree direction are opposite in phase, so that the maximum of the power supply unit is reached. Since it is possible to suppress the current, the maximum output of the power supply unit can be suppressed, and an economical device can be provided.

Further, the detection signal detected by the infrared sensor is monitored every monitoring time Tm seconds, the number of detections within the monitoring time Tm is 3 times or less, and the cumulative detection time S of the detection signal is 0.8 seconds ≦ S ≦. Since it has an erroneous signal determination means that causes the light emitter to blink and emit light only when Tm × 0.95 seconds is satisfied, it is unnecessary due to the factors of sudden noise output and environmental noise generated due to the nature of the infrared sensor. Even if a detection signal is output, unnecessary blinking light can be prevented when there are no wild beasts.

Furthermore, by setting the monitoring time Tm range of the detection signal from 1.2 seconds to 3 seconds, it is effective that the light emitter flashes and emits light when there are no wild vermin due to the factors of sudden noise output and environmental noise. And, it is possible to surely suppress it.

And, as a result of installing this device on private land where wild boars were frequently infested and conducting private experiments, it was possible to confirm the repellent effect against large wild boars such as wild boars for a long period of one year or more. rice field. It also confirmed its repellent effect on deer and other wild vermin.

As mentioned above, the repelling effect is sustained for a long period of time against relatively large wild vermin such as wild boar, and the area range where the repelling effect is exerted without the need for a complicated rotation mechanism or guide rail. It is possible in all directions. Further, it has an effect that it can be provided as an economical device that can prevent a malfunction of blinking light emission due to sudden noise output or environmental noise.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing the entire repelling device according to the embodiment of the present invention, and the repelling device is composed of a rectangular parallelepiped housing 1. Infrared sensors 2a, 2b, 2c, 2d, and light emitters 3a, 3b, 3c, and 3d having a green LED 4a, a red LED 4b, a blue LED 4c, and a reflector 5 are attached to each side surface of the housing 1, respectively. ing. The infrared sensors 2a and 2c are installed at 180 degrees, respectively, and the infrared sensors 2b and 2d are installed at 180 degrees, respectively. Further, the light emitters 3a and 3c are arranged at 180 degrees, respectively, and the light emitters 3b and 3d are also arranged at 180 degrees, respectively.

The upper lid 6 is fixed to the top surface of the housing 1 by the mounting screws 7, and the lower lid (not shown) is attached to the bottom surface and fixed by the mounting screws 8. Therefore, the housing 1 has a rectangular parallelepiped shape in which the upper lid 6 and the lower lid are fixed and can be sealed, and has a structure that is easily dustproof and waterproof and can be installed outdoors such as a field. Further, by forming the mounting portion 9 having the mounting hole 10 in the lower part of the housing 1, the mounting hole 10 can be effectively used to pass the anti-theft chain chain, the anti-theft pile, and the like.

The main SW11 attached to one side surface of the housing 1 turns on / off the power of the entire device. Further, 13 is a day / night switching SW, and 14 is a blinking continuation time switching SW for switching the time for continuing blinking. Reference numeral 15 is an optical sensor, which is composed of cds and whose resistance changes according to the brightness. Sensors SW12a, 12b, 12c, 12d (12c, 12d are not shown) individually turn on / off the infrared sensors 2a, 2b, 2c, and 2d attached to each side surface, and detect wild vermin. The orientation of is arbitrarily selectable.

As described above, since the light emitters 3a, 3b, 3c, and 3d are attached to each side surface of the housing 1 in a form corresponding to the infrared sensors 2a, 2b, 2c, and 2d, they are omnidirectional over 360 degrees in the horizontal direction. It becomes possible to detect wild vermin in the direction. Further, since the light emitters 3a, 3b, 3c, and 3d installed in four directions can be made to blink and emit light, it is possible to repel them in all directions.

FIG. 2 is a diagram showing an LED connection arrangement diagram of a light emitter of the repellent device according to the present invention and a diagram showing the operation of the LED. (A) shows the connection arrangement of the green LED 4a to the light emitters 3a, 3b, 3c and 3d. Since six green LEDs 4a are connected in series and eight are connected in parallel, the light emitters 3a, 3b, 3c, and 3d each have a total of 48 high-brightness green LEDs 4a.

The green LED 4a used has an average luminous flux of 210 lumens at the rated current, and since 48 green LEDs 4a are arranged in one light emitter 3a, 3b, 3c, and 3d, the average luminous flux per light emitter is high. It can have a large average luminous flux of 10080 lumens. Therefore, the light emitters 3a, 3b, 3c, and 3d are repellent devices having a glare that wild vermin dislike due to a strong luminous flux.

V1 is connected to the LED power supply, G is connected to the drive unit, and blinking light is emitted. As shown by the operation of the LED, the blinking light is turned on for 0.15 seconds and turned off for 0.15 seconds repeatedly. If the lighting time and extinguishing time of the blinking light are short, it becomes like continuous irradiation, and if it is long, the passing effect is diminished. Therefore, the lighting time and extinguishing time of the blinking light are in the range of 0.1 to 0.2 seconds. desirable. This time setting is set based on the results confirmed by the demonstration experiment. Further, in (a), 48 green LEDs 4a are connected and arranged, but the three colors of the green LED 4a, the red LED 4b and the blue LED 4c may be divided into 16 equal parts or appropriately changed and arranged.

(B) shows a form in which a green LED 4a, a red LED 4b, and a blue LED 4c are connected and arranged on the light emitters 3a, 3b, 3c, and 3d. Six green LEDs 4a and six blue LEDs 4c are connected in series, and three more are connected in parallel. Since six red LEDs 4b are connected in series and two are connected in parallel, the light emitters 3a, 3b, 3c, and 3d each have a total of 48 connection configurations. And, as shown by the operation of the LED, since the green LED 4a, the red LED 4b and the blue LED 4c are blinking and emitting light in sequence, it is a repellent device having three colors of glare that wild vermin dislike with a strong luminous flux. Therefore, the repellent effect does not diminish. Further, the parallel number of the three colors of the green LED 4a, the red LED 4b and the blue LED 4c may be appropriately changed.

The blinking light of (a) is turned on for 0.15 seconds and turned off for 0.15 seconds, and the blinking light of (b) is turned on for 0.15 seconds and turned off for 0.75 seconds. The time, its cycle, and the ratio of the lighting time to the extinguishing time are not limited to the examples, and can be changed as appropriate. Further, although the green LED 4a, the red LED 4b, and the blue LED 4c are sequentially blinking and emitting light, they may blink and emit light at the same timing.

FIG. 3 is a cross-sectional view taken along the line AA of FIG. 1 for explaining the internal structure of the light emitter according to the embodiment of the present invention. In the figure, the green LED 4a, the red LED 4b, and the blue LED 4c are solder-mounted on the substrate 20 made of an aluminum material. After that, the substrate 20 is fixed to the lower cover 16 with the mounting screws 18. Reference numeral 21 is a protective plate made of transparent acrylic, which is attached to the upper cover 17 by adhesion. On the substrate 20 on which the green LED 4a, the red LED 4b, and the blue LED 4c are solder-mounted, a reflector 5 having a curved reflecting surface 19 formed into a white color by a thermoplastic resin is placed.

After that, the upper cover 17 to which the protective plate 21 is fixed is integrated with the lower cover 16 by the boss portion 22 fixed to the upper cover 17 and the mounting screw 24 to complete the light emitters 3a, 3b, 3c, and 3d. .. After that, the completed light emitters 3a, 3b, 3c, and 3d are attached to the main body case 25 forming the housing 1 by the screw portion 26 of the lower cover 16 and the mounting nut 27.

Since the curved reflective surface 19 of the reflector 5 is shaped so as to be able to diffuse the light of the high-intensity green LED 4a, red LED 4b and blue LED 4c toward the front surface where the wild vermin that repels the light is present, the light that blinks and emits light is emitted. Efficient irradiation is possible because it can be collected without being scattered.

FIG. 4 is a diagram showing a detection area of the infrared sensor of the repellent device according to the present invention, and is a view of the housing 1 as viewed from the top surface side. In the figure, the infrared sensors 2a, 2b, 2c, and 2d are arranged at 90 degree intervals with respect to the center O of the housing 1. Since the detection range of the infrared sensors 2a, 2b, 2c, and 2d of the developed repellent device has 102 degrees in the horizontal direction, a part of the blind spot 30 is generated in the detection area, but in a radius of 4.3 m or more. 360-degree omnidirectional detection is possible, and almost omnidirectional detection is possible without the need for a rotating device or guide rail as in the conventional example.

FIG. 5 is a circuit block configuration diagram of the repellent device according to the present invention. The circuit block is composed of a control unit 32, a power supply unit 33, and drive units 34a, 34b, 34c, and 34d, and is mounted on one control board (not shown). The control unit 32 has an erroneous signal determination means 35, an anti-phase generation means 36, an energization time control means 37, and a day / night switching means 38. Further, the erroneous signal determination means 35, the anti-phase generation means 36, the energization time control means 37, and the day / night switching means 38 are controlled by a microcomputer.

The power supply unit 33 includes an AC-DC converter and a step-down circuit, and supplies drive voltages to the light emitters 3a, 3b, 3c, 3d, the control unit 32, and the infrared sensors 2a, 2b, 2c, and 2d. The day / night switching means 38 uses the output from the optical sensor 15 to switch operation on / off during day / night and enable all-day operation depending on whether the ambient brightness is below or above the set level.

The energization time control means 37 controls the lighting time and the extinguishing time of the blinking light, the cycle thereof, the ratio of the lighting time to the extinguishing time, and the time for continuing the blinking.

When the infrared sensors 2a, 2b, 2c and 2d detect a wild vermin approaching a field or the like, a detection signal is output and input to the control unit 32. Then, the lighting time, the extinguishing time, the ratio thereof, and the blinking duration can be accurately and efficiently controlled by the erroneous signal determining means 35, the antiphase generating means 36, and the energizing time controlling means 37 in the control unit 32.

The blinking duration can be switched between 15 seconds / 23 seconds / 30 seconds, and can be selected by the blinking duration switching SW14 attached to the side surface of the housing 1. The output signal for blinking light emission is output from the control unit 32 to the drive units 34a, 34b, 34c, 34d of the MOSFET or the like to perform blinking light emission of the light emitters 3a, 3b, 3c, and 3d.

FIG. 6 is a waveform diagram showing the detection signal and the operation of the LED when detected by the infrared sensor of the repellent device according to the present invention. The detection signal of (a) is a waveform diagram when the infrared sensors 2a, 2b, 2c, and 2d detect wild vermin. In wild vermin, it was confirmed that the output signal was about 2 to 3 times in terms of the number of pulses. The detection signal of (b) is a waveform diagram due to sudden noise output or the like generated from the nature of the pyroelectric element type infrared sensors 2a, 2b, 2c, and 2d. Further, the detection signal generated by the light rays such as sunlight and reflected light incident on the infrared sensors 2a, 2b, 2c, and 2d even in the absence of wild beasts also appears as such a single pulse. .. According to the empirical experiment, the time width of such a single pulse was mainly in the range of 0.1 seconds to 0.7 seconds. The detection signal of (c) is a waveform when a change in infrared rays caused by fluctuations of trees, plants and leaves located between the infrared sensors 2a, 2b, 2c and 2d and sunlight or reflected light is detected. It is a figure. It has the characteristic that the detection pulse appears continuously.

The erroneous signal determining means 35 monitors the detection signals detected by the infrared sensors 2a, 2b, 2c, and 2d every monitoring time Tm seconds, the number of detections within the monitoring time Tm is 3 times or less, and the detection signal Only when the cumulative detection time S satisfies 0.8 seconds ≦ S ≦ Tm × 0.95 seconds, it is determined that the detection signal is correct, and the light emitters 3a, 3b, 3c, and 3d are made to blink. Specifically, assuming that the monitoring time Tm is 1.5 seconds in the waveform diagram shown in FIG. 5, the number of detections is 3 or less, and the cumulative detection time S of the detection signal is 0.8 seconds ≤ S ≤ 1.425. Only at the time of seconds, the detection signal is determined to be a correct signal, and the light emitters 3a, 3b, 3c, and 3d are blinking and emitting light.

Therefore, when the monitoring time Tm is 1.5 seconds, in the case of (a), the number of detections is 3 and the cumulative detection time S is 0.9 seconds, so that the blinking light is emitted as a correct signal. In the waveform diagram of the LED operation, the error signal determination means 35 determines whether the detection signal is correct or incorrect every Tm seconds of the monitoring time. Therefore, 1.5 seconds after the first rising pulse of the detection signal is the monitoring time Tm. Blinking flashes start. The blinking light emission is repeated for 0.15 seconds and off for 0.15 seconds. In the case of (b), the number of detections is 3 or less, but the cumulative detection time S is 0.4 seconds, so it is determined that this detection signal is not correct and the blinking light is not emitted. In the case of (c), since the number of detections is 4 or more within the monitoring time Tm, it is determined that this detection signal is also incorrect, and the blinking light is not emitted.

Therefore, the erroneous signal determining means 35 monitors the detection signals detected by the infrared sensors 2a, 2b, 2c, and 2d every monitoring time Tm seconds, so that the number of detections within the monitoring time Tm is 3 times or less, and Only when the cumulative detection time S of the detection signal satisfies 0.8 seconds ≦ S ≦ Tm × 0.95 seconds, it is judged that the detection signal is correct, and unnecessary detection signals unrelated to the detection target are removed. Therefore, it is possible to provide a device without unnecessary blinking light emission.

Therefore, since the erroneous signal determination means 35 is provided, an unnecessary detection signal is generated due to the sudden noise output generated due to the nature of the infrared sensors 2a, 2b, 2c, and 2d, and there are no animals. However, light rays such as sunlight and reflected light are incident on the infrared sensors 2a, 2b, 2c, and 2d, and trees located between the infrared sensors 2a, 2b, 2c, and 2d and the sunlight and reflected light. Even if an unnecessary detection signal is generated, it is possible to remove unnecessary detection signals that are not related to the detection target due to environmental noise factors such as detecting changes in infrared rays caused by fluctuations in the wind of plants and leaves. Therefore, the flashing light of the light emitter can be reliably performed only when the detection signal shown in FIG. 6A, that is, the wild vermin is detected by the erroneous signal determining means 35. Further, depending on the installation environment in which unnecessary detection signals such as environmental noise can be ignored, the function of the erroneous signal determination means 35 may be disabled.

FIG. 7 is a waveform diagram showing the timing of the detection signal of the repellent device, the input signal to the drive unit, and the LED drive current according to the present invention. The detection signal and the input signal to the drive unit show the signals at the locations indicated by Sa, Sb, Da, and Db on the block diagram of FIG. The waveforms of the detection signal and the input signal to the drive unit are voltage waveforms, and the horizontal axis is time. The waveform shown by Iled in FIG. 7 is the current waveform of the LED drive current flowing through the light emitters 3a, 3b, 3c, and 3d. Further, in order to facilitate the explanation, in FIG. 7, the function of the erroneous signal determination means 35 will be described as a non-operating state.

FIG. 7A shows an example when the antiphase generating means 36 is not provided. When a wild vermin is detected, Sa, which is the output of the infrared sensor 2a, is input to the control unit 32 and corresponds to the infrared sensor 2a. Da is output to the drive unit 34a, the drive unit 34a performs an on / off operation, the light emitter 3a blinks and emits light, and an LED drive current of i flows through the Iled.

When the infrared sensor 2b detects a wild beast while the light emitter 3a is blinking, Sb, which is the output of the infrared sensor 2b, is input to the control unit 32, and Db is sent to the drive unit 34b corresponding to the infrared sensor 2b. Is output, the drive unit 34b operates on / off, the light emitter 3b also emits blinking light, and the light emitters 3a and 3b simultaneously emit blinking light. Then, when the High portions of Da and Db overlap at this time, the LED is doubled in the range of tw, the LED drive current becomes 2i, and a large LED drive current flows.

FIG. 7B is an example when the antiphase generating means 36 is provided, and when a wild vermin is detected, Sa, which is the output of the infrared sensor 2a, is input to the control unit 32 and corresponds to the infrared sensor 2a. Da is output to the drive unit 34a, the drive unit 34a performs an on / off operation, the light emitter 3a blinks and emits light, and an LED drive current of i flows through the Iled.

When the infrared sensor 2b detects a wild vermin while the light emitter 3a is blinking, Sb, which is the output of the infrared sensor 2b, is input to the control unit 32. When Da is at the Low level at the rise of Sb, which is the output of the infrared sensor 2b, the light emitter 3b blinks and emits light within the time tx from the rise of Sb to the rise of Da, and then Db The anti-phase generating means 36 is provided so as to output in the anti-phase of Da. Therefore, even if the light emitters 3a and 3b simultaneously blink and emit light, the LED drive current does not exceed i because the timings of the blinking light emission of the light emitters 3a and 3b are out of phase.

(C) of FIG. 7 is another example when the antiphase generating means 36 is provided. When a wild vermin is detected, Sa, which is the output of the infrared sensor 2a, is input to the control unit 32 and sent to the infrared sensor 2a. Da is output to the corresponding drive unit 34a, the drive unit 34a performs an on / off operation, the light emitter 3a blinks and emits light, and an LED drive current of i flows through the Iled.

When the infrared sensor 2b detects a wild vermin while the light emitter 3a is blinking, Sb, which is the output of the infrared sensor 2b, is input to the control unit 32. When Da is at the high level at the time of rising of Sb, which is the output of the infrared sensor 2b, the light emitter 3b blinks and emits light after a time ty seconds from the rising of Sb to the falling of Da, and then Db. The anti-phase generating means 36 is provided so as to output in the anti-phase of Da. Therefore, even if the light emitters 3a and 3b simultaneously blink and emit light, the LED drive current does not exceed i because the timings of the blinking light emission of the light emitters 3a and 3b are out of phase.

As described above, since the anti-phase generating means 36 is provided, the LED drive current can suppress the maximum current of the power supply unit 33 even if the light emitters on two adjacent surfaces blink at the same time, so that the power supply unit 33 can be suppressed. It is possible to suppress the maximum output of the LED and provide an economical repellent device. Further, although the timing of the blinking light emission of the two adjacent surfaces is out of phase, the timing of the blinking light of the two surfaces located at the position in the 180 degree direction may be out of phase.

In the present embodiment, the optical sensor 15 is provided on the side surface of the housing 1, but may be installed on the upper lid 6. Further, the repelling device of the present invention is not limited to the above-described embodiment, and can be appropriately changed.
