Description

  The present invention relates to a hunting apparatus and method for effectively threatening and hunting out birds and beasts in order to prevent damage from birds and animals.

  Examples of damage to birds and animals are known to be damage to crops, fruit trees, trees, marine products and garbage, etc. by birds, and damage to crops, fruit trees, trees, etc. by wild animals such as wild boars, monkeys, deers and bears. . In addition to this, there are various damages such as damage to animals including humans, damage to the living environment, damage to damage, etc.

Conventionally, various methods for preventing such damage from birds and animals have been proposed. For example,
(1) Enclose the object to be damaged with a net or electric fence so that birds and beasts cannot come close to it,
(2) A method of capturing birds and beasts using traps and traps,
(3) A method of threatening and driving away birds and beasts by emitting light and sound (for example, Patent Documents 1 and 2),
(4) How to hang carcasses and give fear to birds and beasts,
Etc. have been proposed and implemented. Among these methods, in particular, the method (3) that intimidates by emitting light and sound can be easily implemented with an inexpensive device, and has attracted attention, and many proposals have been made.

  For example, the techniques described in Patent Documents 1 and 2 detect a bird and beast when they approach, cause a thundering sound of explosion and intimidation, and generate a flash to intimidate. According to the techniques described in Patent Documents 1 and 2, it is possible to prevent the birds and beasts from learning the threat and reducing the repelling effect while repeating the threat.

Japanese Patent No. 3704111 JP 2006-158372 A

  However, according to the research by the inventors of the present application, as described in Patent Documents 1 and 2, it is effective at first according to a technology that emits light or sound when birds and animals approach, regardless of whether it is daytime or nighttime. However, when threats are repeated over a long period of time, birds and beasts become accustomed to the threats and the repelling effect is greatly reduced. In addition, there is a problem that making a loud sound regardless of whether it is night or day causes great trouble to the surrounding environment.

  Therefore, the inventors of the present application have earnestly studied a method that can be continuously maintained without reducing the repelling effect over a long period of time by closely observing the behavior and habits of wild boars and deers, and as a result, The present invention has been reached.

  That is, an object of the present invention is to provide a novel bird and animal hunting apparatus and method that can be maintained over a long period of time without reducing the repelling effect due to the threatening action and that does not disturb the surrounding environment.

  According to the present invention, the birds and beasts purging device includes a light sensor, a proximity sensor that outputs a signal indicating the approach of the birds and beasts to be repulsed, and at least one flash light emission source, and can generate flash light. And a control means electrically connected to the optical sensor, the proximity sensor and the flash generation means. The control means generates a flash only when the surrounding environment is darker than the first darkness state determined in advance based on the signal from the optical sensor and the bird and beast to be repulsed approaches based on the signal from the proximity sensor. The means is configured to generate a flash.

  Only when the surrounding environment is darker than the predetermined first dark state and the birds and beasts to be repulsed approach by the signal from the light sensor and the signal from the proximity sensor, the flash light is generated from the flash light source.

  The flash generating means includes a single flash light source, and the bird and animal hunting apparatus is configured to generate a flash by applying a driving current to the single flash light source in response to a control signal from the control means. It is more preferable to further include a light source driving circuit.

  The flash light generating means has a plurality of flash light emission sources, and the bird and animal hunting apparatus generates a flash by applying a drive current to some or all of the plurality of flash light emission sources in accordance with a control signal from the control means. It is preferable to further include a light source driving circuit configured so as to be configured. In this case, based on the signal from the photosensor, the control means is the same as or equal to the predetermined second dark state in which the surrounding environment is darker than the first dark state and darker than the first brightness state. When it is determined that the light is brighter, a drive current is applied to all of the plurality of flash light sources to generate flash light. When it is determined that the light is darker than the second dark state, only a part of the plurality of flash light sources is driven. It is more preferable that a flash is generated by applying an electric current. When the ambient environment is darker than the first threshold state and brighter than the second threshold state, all the flash emission sources are driven, and when the surrounding environment is darker than the second threshold state, some flash emission sources are driven. Drive. That is, for example, if some brightness remains after sunset, a flash is emitted from the entire flash emission source to increase the light intensity, and if it becomes completely dark after sunset, a part of the flash emission source flashes. The light intensity is lowered to a certain degree, so that a constant threat is always given to the birds and beasts.

  It is also preferable that the light emission direction of the flash light from the flash light generation unit and the direction of detecting the approach of the birds and beasts to be repulsed by the proximity sensor are substantially the same direction. Thereby, since it can be flashed from the front of the eyes of the birds and beasts, strong light can be irradiated to the pupil.

  More preferably, the flash light generating means includes a plurality of flash light emission sources, and the plurality of flash light emission sources are arranged so that the flash light is incident on the birds and beasts to be repulsed at different angles. Since the flashlight is incident on the birds and beasts from different flash emission sources at different angles, even if the eyes of the birds and beasts are not facing the determined direction, the probability of being exposed to the flash from the front of the eyes increases. As a result, the possibility that the pupil can be irradiated with strong light is also increased.

  It is also preferable that the control means is configured to flash at least one flash emission source a plurality of times with a set delay time. Since the flash is applied after some delay time from the first flash, the shock to the birds and beasts is very large, and the repelling effect is greatly increased.

  The flash emission source is a xenon flash lamp, and the emission source drive circuit has a trigger switch that operates when a trigger pulse is applied to the xenon flash lamp, and the trigger switch is configured to operate according to a control signal from the control means. It is also preferable that According to the xenon flash lamp, a very large light output can be emitted by a short discharge.

  The bird and animal hunting device further includes an electric field generating electrode at a predetermined position in the direction of detecting the approach of the bird and beast to be repelled, and the light source driving circuit is configured to apply a high potential to the electric field generating electrode, It is also preferable that the means is configured to instruct high-potential application from the light source driving circuit to the electric field generating electrode when instructing the flash generation means to generate flash. Since a high potential electric field is generated from the electric field generating electrode simultaneously with the flash emission, the approaching bird and animal receive not only light but also a high electric field, and an extremely large shock can be effectively applied.

  The flash light source is preferably a high-intensity LED (high-intensity light-emitting diode), and the light source driving circuit is preferably a high-intensity LED driving circuit. According to the high-intensity LED, a high voltage generation circuit such as a xenon flash lamp is not required, so that the circuit configuration is simplified and the manufacturing cost can be greatly reduced.

  The bird and animal hunting apparatus further includes a shock voltage drive circuit for applying a voltage for electric shock between a plurality of wires having conductive surfaces, and the control means performs shock when instructing the flash generation means to generate flash. It is also preferable that a voltage application circuit for electric shock is instructed between a plurality of wires from the voltage drive circuit. Since the electric shock voltage is applied to the wires that make up the so-called electric fence at the same time that the flash is generated, not only the light but also the electric shock due to contact with the electric fence is given to the birds and beasts. Can be effectively given to birds and beasts. And since the voltage for an electric shock is not always applied to an electric fence, useless power consumption at the time of standby can be suppressed.

  A plurality of light generation units each having the flash generation means and the proximity sensor described above, and a main unit having a single control means and a single light sensor electrically connected to the plurality of light generation units. It is also preferable.

  According to the present invention, there is further provided a method for driving away birds and beasts that detects that the surrounding environment is darker than a predetermined dark state and generates flash only when the approach of a bird and beast to be repelled is detected.

  It is preferable to apply a high potential to the electric field generating electrode when the flash is generated.

  It is also preferable to generate a flash in substantially the same direction as the direction in which the approach of a bird to be repelled is detected. Thereby, since light can be poured from the front of the birds and beasts eyes, strong light can be irradiated to the pupil.

  It is also preferable that flashes are incident on the birds and beasts to be repelled at different angles. Thereby, even when the eyes of the birds and beasts are not facing the determined direction, the probability of being flashed from the front of the eyes is increased, and as a result, the possibility that the pupil can be irradiated with strong light is also increased.

  Nocturnal birds and wild animals such as wild boars and deer are repelled by surprise when they are exposed to light or sound in a bright environment. End up. On the other hand, as in the present invention, when the surrounding environment is bright, if nothing is done and the flash is applied only when the surrounding environment is dark, strong light is incident on the eye with the pupil wide open. Therefore, it can give a tremendous shock to birds and beasts. This shock is so large that it cannot be easily recovered in a short time, and once repelled by the device of the present invention, the birds and animals will not appear again, and the repelling effect will remain intact over time. Moreover, since it does not generate a loud sound, it does not disturb the surrounding environment at night.

  FIG. 1 schematically shows the overall configuration of the bird and animal hunting apparatus according to the first embodiment of the present invention, and FIG. 2 schematically shows the electrical configuration of the bird and animal hunting apparatus.

  In FIG. 1, 10 is a xenon flash lamp which is a light source for generating flash light, 11 is a reflector for increasing the brightness of the flash light and imparting directivity to the flash light, and 12 is a discharge electrode (anode and cathode) of the xenon flash lamp 10. ) And a trigger driving electrode, and a lamp driving circuit for generating a flash by applying a discharge current to the xenon flash lamp 10, and 13 detects the brightness (or darkness) of the surrounding environment. An optical sensor 14 is a proximity sensor that detects the approach of birds and beasts to be repulsed, and 15 is electrically connected to the lamp driving circuit 12, the optical sensor 13, and the proximity sensor 14, and is detected from the optical sensor 13 and the proximity sensor 14. The control circuit 15 that controls the operation of the lamp driving circuit 12 according to the signal supplies power to the lamp driving circuit 12 and the control circuit 15. It shows a power supply circuit for performing each.

  In this case, it is important that the direction of the flash emitted from the xenon flash lamp 10 is substantially the same as the direction in which the proximity sensor 14 detects the approach of the birds and beasts. If the direction is the same, a flash will be emitted in the direction in which the birds and beasts approach, and the flash will be directed toward the front of the birds and beasts.

  The xenon flash lamp 10 has a small amount of xenon gas sealed in a transparent glass tube, discharge electrodes (anode and cathode) at both ends, and trigger electrodes along the glass tube. It is possible to emit a very large light output. In the present embodiment, a commercially available xenon flash lamp is used as the xenon flash lamp 10.

  In this embodiment, for example, a CdS optical sensor is used as the optical sensor 13. This CdS optical sensor is an optical sensor that uses cadmium sulfide (CdS), which is a compound semiconductor. By applying light, free electrons proportional to the amount of light are generated in the semiconductor, and the current is changed to change the resistance value. Reduce. Based on the difference between light resistance and dark resistance, it is possible to detect that the surrounding environment has become darker than a predetermined dark state, for example, that it has become a low light state after sunset and the dusk has ended. Yes, such CdS optical sensors are commercially available. Instead of the CdS optical sensor, an optical sensor using a CdSe cell, a PbS cell, another photoresistor, a photodiode, a phototransistor, a photo IC, a solar cell, or the like may be used.

  In the present embodiment, the proximity sensor 14 uses, for example, a pyroelectric infrared sensor. This pyroelectric infrared sensor detects slight infrared rays emitted from birds and beasts using the pyroelectric effect of a ferroelectric ceramic, and is commercially available. Instead of a pyroelectric infrared sensor, an infrared proximity sensor that combines a light emitting element that emits infrared light and a light receiving element that receives reflected infrared light, an electrostatic proximity sensor that detects changes in capacitance, and vibration that emits ultrasonic waves An ultrasonic proximity sensor combining an element and an element that receives reflected ultrasonic waves, or a radar proximity sensor using a radar may be used.

  The power supply circuit 16 is configured to be able to supply a direct current voltage to the lamp driving circuit 12 and the control circuit 15, and in the present embodiment, a rechargeable vehicle battery, for example, is used. Instead of the battery, a commercial power source and an AC / DC converter that converts the commercial power source voltage into a DC voltage may be used. Of course, the solar battery panel may be used to charge the battery with sunlight in the daytime.

  As shown in FIG. 2, the lamp driving circuit 12 includes a charging switch 12a, a DC-DC converter 12b that boosts a low battery voltage to a high voltage, a discharge capacitor 12c, and a trigger circuit including a trigger switch 12d. 12e.

  The charging switch 12a may be a mechanical switch configured to operate according to an instruction from the control circuit 15, or may be a transistor or a semiconductor switch such as an SCR that operates according to an instruction from the control circuit 15. Also good.

In this embodiment, the DC-DC converter 12b uses a forward converter that boosts a battery voltage of about 5 to 12V to a high voltage of about 250 to 500V. The converter includes a transistor for the flash H _FE is larger at a large current and saturation, and oscillation transformer commensurate with the power supply voltage to, a diode.

  The discharge capacitor 12c is a high withstand voltage electrolytic capacitor designed for a strobe.

  The trigger circuit 12e is a circuit for applying a trigger voltage of several thousand volts to the xenon flash lamp 10 via the trigger electrode 10a, and includes a high resistance, a trigger capacitor, a trigger transformer, and a trigger switch 12d.

  The trigger switch 12d may be a mechanical switch configured to operate according to an instruction from the control circuit 15, or may be a transistor or a semiconductor switch such as an SCR that operates according to an instruction from the control circuit 15. good.

  In the present embodiment, as shown in FIG. 2, the control circuit 15 receives detection signals from the optical sensor 13 and the proximity sensor 14, and outputs a control signal for controlling the charging switch 12a and the trigger switch 12d. It consists of a computer. This microcomputer has an MPU that performs arithmetic processing, a ROM that stores processing programs and data, a RAM that temporarily stores information and results necessary for processing, and an input / output device that performs input / output with external devices. It is a general one including an output port I / O and the like. Needless to say, the function of the control circuit 15 may be achieved by a hardware circuit such as a comparator or a logic circuit.

  FIG. 3 illustrates the control operation of the control circuit 15 in the first embodiment. In the present embodiment, the processing routine shown in the figure is executed at regular intervals.

  In this processing routine, first, a signal from the optical sensor 13 is detected via the input / output port I / O (step S1).

  Next, it is determined from this detection signal whether the surrounding environment has become darker than a predetermined dark state (step S2). When the optical sensor 13 which is a CdS optical sensor has a comparison function, a binary signal indicating whether the surrounding environment has become darker than a predetermined dark state is input from the optical sensor 13. The signal becomes the discrimination signal as it is. On the other hand, when the optical sensor 13 does not have such a comparison function and outputs a detection signal having a value corresponding to the darkness, the detection signal is A / D converted and then compared with a threshold value. Judgment is made.

  If it is determined that the surrounding environment is not darker than the predetermined dark state (in the case of NO), the process proceeds to step S8, and the charge switch 12a is left in the off state, and this processing routine is ended. On the other hand, when it is determined that the surrounding environment is darker than a predetermined dark state (in the case of YES), a control signal for turning on the charging switch 12a is sent to the charging switch 12a via the input / output port I / O. (Step S3).

  In the lamp driving circuit 12, when the charging switch 12a is turned on, the DC-DC converter 12b operates and the discharge capacitor 12c is charged. At the same time, the trigger capacitor of the trigger circuit 12e is also charged through a high resistance.

  Next, a signal from the proximity sensor 14 is detected via the input / output port I / O (step S4).

  Next, it is determined from this detection signal whether or not a nocturnal bird or a wild animal such as a wild boar, a monkey or a deer has approached (step S5). When the proximity sensor 14 which is a pyroelectric infrared sensor has a comparison function, a binary signal indicating whether or not the proximity sensor 14 is approaching is input from the proximity sensor 14, so that the signal is directly used as a determination signal. On the other hand, when the proximity sensor 14 does not have such a comparison function and outputs a detection signal having a value corresponding to the approach distance, the detection signal is A / D converted and then compared with a threshold value. Judgment is made.

  When it is determined that the birds and beasts are not approaching (in the case of NO), the process returns to step S4, and the processing of this signal detection (step S4) and determination (step S5) is repeated. On the other hand, if it is determined that a bird or animal has approached (in the case of YES), a control signal for turning on the trigger switch 12d is sent to the trigger switch 12d via the input / output port I / O (step S6).

  In the lamp driving circuit 12, when the trigger switch 12d is turned on, the trigger capacitor is discharged and the charge flows through the primary winding of the trigger transformer. Therefore, a pulse voltage of several thousand volts is applied to the secondary winding of the trigger transformer. Will occur. This pulse voltage is applied to the trigger electrode 10a close to the entire tube of the xenon flash lamp 10, and the high-voltage electric field is transmitted into the tube through the tube wall of the lamp to ionize the xenon gas and excite a small discharge. As a result, avalanche occurs, and the electric charge of the discharge capacitor 12c is discharged at once, and arc discharge is started between the discharge electrodes (anode and cathode). When the arc discharge is started, the inside of the tube is almost short-circuited, so that the electric charge of the discharge capacitor 12c is instantaneously discharged and a flash is generated.

  Since this flash has directivity and is directed toward the bird and animal approaching, the bird and animal are exposed to strong light from the front of their eyes. In addition, since the surrounding environment is darker than the predetermined dark state and the target to be repulsed approaches, the flash is applied from the front of the eyes, so that strong light is applied to the birds and beasts with the pupil wide open. The Rukoto.

  Next, a control signal for turning off the trigger switch 12d is sent via the input / output port I / O to turn off the trigger switch 12d (step S7).

  Next, a control signal for turning off the charging switch 12a is sent via the input / output port I / O to turn off the charging switch 12a (step S8), and this processing routine is ended. In addition, when the voltage of the discharge capacitor 12c and the trigger capacitor decreases due to the discharge, the discharge naturally stops, and these capacitors are charged again if the charge switch 12a is on.

  As described above, according to the present embodiment, the control circuit 15 should be repelled by the signal from the optical sensor 13 and the signal from the proximity sensor 14 so that the surrounding environment is darker than the predetermined dark state. A flash is generated from the front only when a bird or beast approaches. Nocturnal birds and wild animals such as wild boars and deer are exposed to light or sound in a bright environment, or repeatedly generate light or sound at regular intervals even in a dark environment. At that point, you will be surprised and repelled, but if you repeat this many times, the repelling effect will fade. On the other hand, in this embodiment, when the surrounding environment is bright, nothing is done and the surrounding environment is darker than a predetermined dark state and only when the birds and beasts are approaching, it is flashed from the front in the approaching direction. In the state where the pupil is wide open, strong light is applied to the eye. As a result, a tremendous shock can be given to birds and beasts. This shock is so large that it cannot be easily recovered in a short time. Once repelled, the birds and beasts will not appear again, and the repelling effect will remain intact for a long time. Moreover, since it does not generate a loud sound, it does not disturb the surrounding environment at night.

  The electrical configuration of the present embodiment described above is merely an example, and it is needless to say that the present embodiment can be configured in various other forms.

  FIG. 4 schematically shows the overall configuration of the bird and animal hunting apparatus according to the second embodiment of the present invention, and FIG. 5 schematically shows the electrical configuration of the bird and animal hunting apparatus.

  As apparent from FIGS. 4 and 5, in the present embodiment, the electric field generating electrode 17 is added to the configuration of the first embodiment, and a lamp driving and electric field generating circuit 42 is provided in place of the lamp driving circuit. And a control circuit 45 is provided in place of the control circuit 15. Other configurations in the second embodiment are substantially the same as those in the first embodiment. Therefore, the same constituent elements are denoted by the same reference numerals.

  As shown in FIGS. 4 and 5, the electric field generating electrode 17 is electrically connected to one discharge electrode (anode) of the xenon flash lamp 10, and is configured by a mesh electrode in the present embodiment. ing. Note that the electric field generating electrode 17 may be replaced with a mesh electrode, and a plurality of single wires may be simply extended. The other discharge electrode (cathode) of the xenon flash lamp 10 is grounded.

  The electric field generating electrode 17 is detected as a predetermined position ahead in the direction of the flash emitted from the xenon flash lamp 10 (the direction in which the proximity sensor 14 detects the approach of the birds and animals), that is, the proximity sensor 14 detects that the birds and animals have approached. It is important that it is installed in position. Thereby, when the birds and beasts approach, the electric field generated simultaneously with the flash can be applied to the birds and beasts.

  The power supply circuit 16 is configured to be able to supply a DC voltage to the lamp driving and electric field generating circuit 42 and the control circuit 45, and in the present embodiment, a rechargeable vehicle battery, for example, is used. Instead of the battery, a commercial power source and an AC / DC converter that converts the commercial power source voltage into a DC voltage may be used. Of course, the solar battery panel may be used to charge the battery with sunlight in the daytime.

  As shown in FIG. 5, the lamp driving and electric field generating circuit 42 includes a charging switch 42a, a DC-DC converter 42b that boosts a low battery voltage to a high voltage, a discharge capacitor 42c, and a trigger switch 42d. A trigger circuit 42e and an electric field generation switch 42f.

  The electric field generation switch 42f may be a mechanical switch configured to operate according to an instruction from the control circuit 45, or may be a transistor or a semiconductor switch such as an SCR that operates according to an instruction from the control circuit 45. Also good.

  In the present embodiment, as shown in FIG. 5, the control circuit 45 receives detection signals from the optical sensor 13 and the proximity sensor 14, and controls the charging switch 42a, the trigger switch 42d, and the electric field generation switch 42f. It consists of a microcomputer that outputs signals. This microcomputer has an MPU that performs arithmetic processing, a ROM that stores processing programs and data, a RAM that temporarily stores information and results necessary for processing, and an input / output device that performs input / output with external devices. It is a general one including an output port I / O and the like. Needless to say, the function of the control circuit 45 may be achieved by a hardware circuit such as a comparator or a logic circuit.

  FIG. 6 illustrates the control operation of the control circuit 45 in the second embodiment. In the present embodiment, the processing routine shown in the figure is executed at regular intervals.

  In this processing routine, first, a signal from the optical sensor 13 is detected via the input / output port I / O (step S11).

  Next, it is determined from this detection signal whether the surrounding environment has become darker than a predetermined dark state (step S12). When the optical sensor 13 which is a CdS optical sensor has a comparison function, a binary signal indicating whether the surrounding environment has become darker than a predetermined dark state is input from the optical sensor 13. The signal becomes the discrimination signal as it is. On the other hand, when the optical sensor 13 does not have such a comparison function and outputs a detection signal having a value corresponding to the darkness, the detection signal is A / D converted and then compared with a threshold value. Judgment is made.

  If it is determined that the surrounding environment is not darker than the predetermined dark state (in the case of NO), the process proceeds to step S19, and the charge switch 42a remains in the OFF state, and this processing routine is ended. On the other hand, when it is determined that the surrounding environment is darker than a predetermined dark state (in the case of YES), a control signal for turning on the charging switch 42a is sent to the charging switch 42a via the input / output port I / O. (Step S13).

  In the lamp driving and electric field generating circuit 42, when the charging switch 42a is turned on, the DC-DC converter 42b operates and the discharge capacitor 42c is charged. At the same time, the trigger capacitor of the trigger circuit 42e is charged through the high resistance.

  Next, a signal from the proximity sensor 14 is detected via the input / output port I / O (step S14).

  Next, it is determined from this detection signal whether or not a nocturnal bird or a wild animal such as a wild boar, a monkey or a deer has approached (step S15). When the proximity sensor 14 which is a pyroelectric infrared sensor has a comparison function, a binary signal indicating whether or not the proximity sensor 14 is approaching is input from the proximity sensor 14, so that the signal is directly used as a determination signal. On the other hand, when the proximity sensor 14 does not have such a comparison function and outputs a detection signal having a value corresponding to the approach distance, the detection signal is A / D converted and then compared with a threshold value. Judgment is made.

  When it is determined that the birds and beasts are not approaching (in the case of NO), the process returns to step S14, and the processing of this signal detection (step S14) and determination (step S15) is repeated. On the other hand, if it is determined that a bird or animal has approached (in the case of YES), a control signal for turning on the trigger switch 42d is sent to the trigger switch 42d via the input / output port I / O (step S16). Almost simultaneously, a control signal for turning on the electric field generating switch 42f is sent to the electric field generating switch 42f via the input / output port I / O (step S17).

  In the lamp driving and electric field generating circuit 42, when the trigger switch 42d is turned on, the trigger capacitor is discharged and the electric charge flows through the primary winding of the trigger transformer. The pulse voltage is generated. This pulse voltage is applied to the trigger electrode 10a close to the entire tube of the xenon flash lamp 10, and the high-voltage electric field is transmitted into the tube through the tube wall of the lamp to ionize the xenon gas and excite a small discharge. As a result, avalanche occurs, and the electric charge of the discharge capacitor 42c is discharged at once, and arc discharge is started between the discharge electrodes (anode and cathode). When the arc discharge starts, the inside of the tube is almost short-circuited, so that the electric charge of the discharge capacitor 42c is instantaneously discharged and a flash is generated.

  Since this flash has directivity and is directed toward the bird and animal approaching, the bird and animal are exposed to strong light from the front of their eyes. In addition, since the surrounding environment is darker than the predetermined dark state and the target to be repulsed approaches, the flash is applied from the front of the eyes, so that strong light is applied to the birds and beasts with the pupil wide open. The Rukoto.

  On the other hand, in the lamp driving and electric field generating circuit 42, when the electric field generating switch 42f is turned on, the high potential of the discharge capacitor 42c is also applied to the electric field generating electrode 17, and a high potential electric field is generated around it. As a result, a high-potential electric field is applied to the birds and beasts, and for example, they are shocked by being stimulated by an electric field induced on the surface of the living body or receiving a physiological action by an electric current induced in the body.

  Thus, according to this embodiment, both the above-described flashlight enters the pupil and a high-potential electric field is applied.

  Next, a control signal for turning off the trigger switch 42d and the electric field generation switch 42f is sent via the input / output port I / O to turn off the trigger switch 42d and the electric field generation switch 42f (step S18).

  Next, a control signal for turning off the charging switch 42a is sent via the input / output port I / O to turn off the charging switch 42a (step S19), and this processing routine is ended. In addition, when the voltage of the discharge capacitor 42c and the trigger capacitor decreases due to the discharge, the discharge naturally stops, and these capacitors are charged again if the charge switch 42a is on.

  As described above, according to the present embodiment, the control circuit 15 should be repelled by the signal from the optical sensor 13 and the signal from the proximity sensor 14 so that the surrounding environment is darker than the predetermined dark state. A flash is generated from the front only when a bird or beast approaches. At the same time, a high potential electric field is applied. Nocturnal birds and wild animals such as wild boars and deer are exposed to light or sound in a bright environment, or repeatedly generate light or sound at regular intervals even in a dark environment. At that point, you will be surprised and repelled, but if you repeat this many times, the repelling effect will fade. On the other hand, in this embodiment, when the surrounding environment is bright, nothing is done and the surrounding environment is darker than a predetermined dark state and only when the birds and beasts are approaching, it is flashed from the front in the approaching direction. In the state where the pupil is wide open, strong light is applied to the eye. At the same time, a high potential electric field is applied. Due to the synergistic effect of flashing an open pupil and applying a high potential electric field, a tremendous shock can be given to birds and beasts. This shock is so large that it cannot be easily recovered in a short time. Once repelled, the birds and beasts will not appear again, and the repelling effect will remain intact for a long time. Moreover, since it does not generate a loud sound, it does not disturb the surrounding environment at night.

  The electrical configuration of the present embodiment described above is merely an example, and it is needless to say that the present embodiment can be configured in various other forms.

  FIG. 7 schematically shows the overall configuration of the bird and animal hunting apparatus according to the third embodiment of the present invention, and FIG. 8 schematically shows the electrical configuration of the bird and animal hunting apparatus.

  As is apparent from FIGS. 7 and 8, the present embodiment is obtained by adding an electric fence drive circuit 18 and an electric fence (not shown) driven by the electric fence drive circuit to the configuration of the first embodiment. Other configurations in the third embodiment are substantially the same as those in the first embodiment, and therefore, the same components are represented by using the same reference numerals.

  As shown in FIGS. 7 and 8, the electric fence drive circuit 18 includes a control circuit 75, an electric fence that is not shown but has a plurality of bare wires well known in the art, and a commercial power source (not shown). In response to a drive instruction from the control circuit 75, an electric shock voltage is applied between the wires of the electric fence. In this embodiment, the voltage for electric shock is generated by converting the commercial power supply voltage into a high voltage in the electric fence drive circuit 18, but the xenon flash lamp 10 is used as in the second embodiment. A high voltage for driving may be used.

  This electric fence is installed to surround the object to be protected, and in particular, a predetermined position ahead in the direction of the flash emitted from the xenon flash lamp 10 (the direction in which the proximity sensor 14 detects the approach of a bird and beast), that is, A part of the proximity sensor 14 is also installed at a position where the proximity sensor 14 detects that the birds and animals are approaching. As a result, when the birds and beasts approach, it is possible to drive the electric fence simultaneously with the flash and apply a greater shock to the birds and beasts.

  The power supply circuit 16 is configured to be able to supply a DC voltage to the lamp driving circuit 12 and the control circuit 75, and in the present embodiment, a rechargeable vehicle battery, for example, is used. Instead of the battery, a commercial power source and an AC / DC converter that converts the commercial power source voltage into a DC voltage may be used. Of course, the solar battery panel may be used to charge the battery with sunlight in the daytime.

  The electric fence drive circuit 18 is configured to receive a control signal for driving the trigger switch 12d from the control circuit 75 and apply a voltage for electric shock to the electric fence.

  In this embodiment, as shown in FIG. 8, the control circuit 75 receives detection signals from the optical sensor 13 and the proximity sensor 14 and controls the charging switch 12a, the trigger switch 12d, and the electric fence driving circuit 18. It consists of a microcomputer that outputs control signals. This microcomputer has an MPU that performs arithmetic processing, a ROM that stores processing programs and data, a RAM that temporarily stores information and results necessary for processing, and an input / output device that performs input / output with external devices. It is a general one including an output port I / O and the like. Needless to say, the function of the control circuit 75 may be achieved by a hardware circuit such as a comparator or a logic circuit.

  FIG. 9 illustrates the control operation of the control circuit 75 in the third embodiment. In the present embodiment, the processing routine shown in the figure is executed at regular intervals.

  In this processing routine, first, a signal from the optical sensor 13 is detected via the input / output port I / O (step S21).

  Next, it is determined from this detection signal whether or not the surrounding environment has become darker than a predetermined dark state (step S22). When the optical sensor 13 which is a CdS optical sensor has a comparison function, a binary signal indicating whether the surrounding environment has become darker than a predetermined dark state is input from the optical sensor 13. The signal becomes the discrimination signal as it is. On the other hand, when the optical sensor 13 does not have such a comparison function and outputs a detection signal having a value corresponding to the darkness, the detection signal is A / D converted and then compared with a threshold value. Judgment is made.

  If it is determined that the surrounding environment is not darker than the predetermined dark state (in the case of NO), the process proceeds to step S29, and the charge switch 12a remains in the OFF state, and this processing routine is ended. On the other hand, when it is determined that the surrounding environment is darker than a predetermined dark state (in the case of YES), a control signal for turning on the charging switch 12a is sent to the charging switch 12a via the input / output port I / O. (Step S23).

  In the lamp driving circuit 12, when the charging switch 12a is turned on, the DC-DC converter 12b operates and the discharge capacitor 12c is charged. At the same time, the trigger capacitor of the trigger circuit 12e is also charged through a high resistance.

  Next, a signal from the proximity sensor 14 is detected via the input / output port I / O (step S24).

  Next, it is determined from this detection signal whether or not a nocturnal bird or a wild animal such as a wild boar, a monkey or a deer has approached (step S25). When the proximity sensor 14 which is a pyroelectric infrared sensor has a comparison function, a binary signal indicating whether or not the proximity sensor 14 is approaching is input from the proximity sensor 14, so that the signal is directly used as a determination signal. On the other hand, if the proximity sensor 14 does not have a comparison function, the detection signal is A / D converted and then compared with a threshold value.

  When it is determined that the birds and beasts are not approaching (in the case of NO), the process returns to step S24, and the processing of this signal detection (step S24) and determination (step S25) is repeated. On the other hand, if it is determined that a bird or animal has approached (YES), a control signal for turning on the trigger switch 12d is sent to the trigger switch 12d via the input / output port I / O (step S26). Almost simultaneously, the same control signal is sent to the electric fence drive circuit 18 via the input / output port I / O (step S27).

  In the lamp driving circuit 12, when the trigger switch 12d is turned on, the trigger capacitor is discharged and the charge flows through the primary winding of the trigger transformer. Therefore, a pulse voltage of several thousand volts is applied to the secondary winding of the trigger transformer. Will occur. This pulse voltage is applied to the trigger electrode 10a close to the entire tube of the xenon flash lamp 10, and the high-voltage electric field is transmitted into the tube through the tube wall of the lamp to ionize the xenon gas and excite a small discharge. As a result, avalanche occurs, and the electric charge of the discharge capacitor 12c is discharged at once, and arc discharge is started between the discharge electrodes (anode and cathode). When the arc discharge is started, the inside of the tube is almost short-circuited, so that the electric charge of the discharge capacitor 12c is instantaneously discharged and a flash is generated.

  Since this flash has directivity and is directed toward the bird and animal approaching, the bird and animal are exposed to strong light from the front of their eyes. In addition, since the surrounding environment is darker than the predetermined dark state and the target to be repulsed approaches, the flash is applied from the front of the eyes, so that strong light is applied to the birds and beasts with the pupil wide open. The Rukoto.

  On the other hand, when the same control signal is sent to the electric fence driving circuit 18, the electric fence driving circuit 18 applies a voltage for electric shock to the electric fence. For this reason, the invading birds and beasts are not only flashed, but also receive an electric shock by touching the electric fence.

  Thus, according to this embodiment, both the flash enters the pupil and receives an electric shock from the electric fence.

  Next, a control signal for turning off the trigger switch 12d and the electric field generating switch 12f is sent via the input / output port I / O to turn off the trigger switch 12d (step S28).

  Next, a control signal for turning off the charging switch 12a is sent via the input / output port I / O to turn off the charging switch 12a (step S29), and this processing routine is ended. In addition, when the voltage of the discharge capacitor 12c and the trigger capacitor decreases due to the discharge, the discharge naturally stops, and these capacitors are charged again if the charge switch 12a is on.

  As described above, according to the present embodiment, the control circuit 75 should repel the surrounding environment darker than the predetermined dark state by the signal from the optical sensor 13 and the signal from the proximity sensor 14. A flash is generated from the front only when a bird or beast approaches. At the same time, a voltage for electric shock is applied to the electric fence. Nocturnal birds and wild animals such as wild boars and deer are exposed to light or sound in a bright environment, or repeatedly generate light or sound at regular intervals even in a dark environment. At that point, you will be surprised and repelled, but if you repeat this many times, the repelling effect will fade. On the other hand, in this embodiment, when the surrounding environment is bright, nothing is done and the surrounding environment is darker than a predetermined dark state and only when the birds and beasts are approaching, it is flashed from the front in the approaching direction. In the state where the pupil is wide open, strong light is applied to the eye. Moreover, since a shock voltage is applied to the electric fence, when the bird touches the electric fence, it receives a large electric shock. Due to the synergistic effect of flash irradiation on the open pupil and electric shock from the electric fence, it is possible to give an extremely large shock to the birds and beasts. This shock is so large that it cannot be easily recovered in a short time. Once repelled, the birds and beasts will not appear again, and the repelling effect will remain intact for a long time. And since the voltage for an electric shock is not always applied to an electric fence, useless power consumption at the time of standby can be suppressed. Moreover, since it does not generate a loud sound, it does not disturb the surrounding environment at night.

  The electrical configuration of the present embodiment described above is merely an example, and it is needless to say that the present embodiment can be configured in various other forms.

  Further, the third embodiment described above may be combined with the second embodiment described with reference to FIGS.

  FIG. 10 schematically shows the entire configuration of the bird and animal hunting apparatus according to the fourth embodiment of the present invention, and FIG. 11 schematically shows the electrical configuration of the bird and animal hunting apparatus.

  As apparent from FIGS. 10 and 11, the present embodiment is configured to have a single xenon flash lamp 10 in the first embodiment, but the two xenon flash lamps 100 and 110 and their flashlights. The control circuit 15 includes two lamp driving circuits 102 and 112 that drive the xenon flash lamps 100 and 110, respectively, and have reflectors 101 and 111 for increasing the luminance and directing the flash light. Instead, a control circuit 105 is provided. Other configurations in the fourth embodiment are substantially the same as those in the first embodiment, and therefore, the same components are represented by using the same reference numerals.

  As shown in FIGS. 10 and 11, the two xenon flash lamps 100 and 110 are arranged so that their irradiation directions are directed forward and in the central direction. As a result, flashlight is incident on the birds and beasts that are to be repulsed from both directions obliquely forward rather than from the front. As described above, since the flashlights are simultaneously incident on the birds and beasts from the two xenon flash lamps 100 and 110 at different angles, the flashlights from the front of the eyes even when the eyes of the birds and beasts are not directed. As a result, the possibility of being able to irradiate the pupil with strong light is also increased.

  The power supply circuit 16 is configured to be able to supply a DC voltage to the two lamp driving circuits 102 and 112 and the control circuit 105, and in the present embodiment, a rechargeable vehicle battery, for example, is used. Instead of the battery, a commercial power source and an AC / DC converter that converts the commercial power source voltage into a DC voltage may be used. Of course, the solar battery panel may be used to charge the battery with sunlight in the daytime.

  The lamp driving circuits 102 and 112 are circuits for driving the xenon flash lamps 100 and 110, respectively. As shown in FIG. 11, the lamp driving circuits 102 and 112 include charging switches 102a and 112a, DC-DC converters 102b and 112b that boost a low battery voltage to a high voltage, discharge capacitors 102c and 112c, , Trigger circuits 102e and 112e provided with trigger switches 102d and 112d, respectively.

  In the present embodiment, as shown in FIG. 11, the control circuit 105 receives detection signals from the optical sensor 13 and the proximity sensor 14, and controls the charging switches 102a and 112a and the trigger switches 102d and 112d. It is comprised from the microcomputer which outputs. This microcomputer has an MPU that performs arithmetic processing, a ROM that stores processing programs and data, a RAM that temporarily stores information and results necessary for processing, and an input / output device that performs input / output with external devices. It is a general one including an output port I / O and the like. Needless to say, the function of the control circuit 105 may be achieved by a hardware circuit such as a comparator or a logic circuit.

  FIG. 12 explains the control operation of the control circuit 105 in the fourth embodiment. In the present embodiment, the processing routine shown in the figure is executed at regular intervals.

  In this processing routine, first, a signal from the optical sensor 13 is detected via the input / output port I / O (step S31).

  Next, it is determined from this detection signal whether or not the surrounding environment has become darker than a predetermined dark state (step S32). When the optical sensor 13 which is a CdS optical sensor has a comparison function, a binary signal indicating whether the surrounding environment has become darker than a predetermined dark state is input from the optical sensor 13. The signal becomes the discrimination signal as it is. On the other hand, when the optical sensor 13 does not have such a comparison function and outputs a detection signal having a value corresponding to the darkness, the detection signal is A / D converted and then compared with a threshold value. Judgment is made.

  When it is determined that the surrounding environment is not darker than the predetermined dark state (in the case of NO), the process proceeds to step S38, and the charge switches 102a and 112a are left in the off state, and this processing routine is ended. On the other hand, when it is determined that the surrounding environment is darker than the predetermined dark state (in the case of YES), a control signal for turning on the charging switches 102a and 112a is sent via the input / output port I / O. And 112a (step S33).

  In the lamp driving circuits 102 and 112, when the charging switches 102a and 112a are turned on, the DC-DC converters 102b and 112b operate to charge the discharge capacitors 102c and 112c, respectively. At the same time, the trigger capacitors of the trigger circuits 102e and 112e are also charged through the high resistance, respectively.

  Next, a signal from the proximity sensor 14 is detected via the input / output port I / O (step S34).

  Next, it is determined from this detection signal whether or not a nocturnal bird or a wild animal such as a wild boar, a monkey or a deer has approached (step S35). When the proximity sensor 14 which is a pyroelectric infrared sensor has a comparison function, a binary signal indicating whether or not the proximity sensor 14 is approaching is input from the proximity sensor 14, so that the signal is directly used as a determination signal. On the other hand, when the proximity sensor 14 does not have such a comparison function and outputs a detection signal having a value corresponding to the approach distance, the detection signal is A / D converted and then compared with a threshold value. Judgment is made.

  When it is determined that the birds and beasts are not approaching (in the case of NO), the process returns to step S34, and the processing of this signal detection (step S34) and determination (step S35) is repeated. On the other hand, when it is determined that the birds and beasts have approached (in the case of YES), a control signal for turning on the trigger switches 102d and 112d is sent to the trigger switches 102d and 112d via the input / output port I / O, respectively (step S36). ).

  In the lamp driving circuits 102 and 112, when the trigger switches 102d and 112d are turned on, the trigger capacitor is discharged and the electric charge flows through the primary winding of the trigger transformer. A pulse voltage of V is generated. This pulse voltage is applied to trigger electrodes 100a and 110a adjacent to the entire tubes of the xenon flash lamps 100 and 110, respectively, and the high-voltage electric field is transmitted into the tube through the tube wall of the lamp to ionize the xenon gas and reduce it. Excites the discharge. As a result, an avalanche occurs, and the electric charges of the discharge capacitors 102c and 112c are discharged at once, and arc discharge starts between the discharge electrodes (anode and cathode), respectively. When the arc discharge starts, the inside of the tube is almost short-circuited, so that the electric charges of the discharge capacitors 102c and 112c are instantaneously discharged, and flashing is simultaneously generated from the xenon flash lamps 100 and 110.

  This flash has directivity and is applied simultaneously from both light beams obliquely forward of the approaching birds and beasts, so even if the eyes of the birds and animals are not facing the determined direction, they flash from the front of the eyes. As a result, the possibility of being able to irradiate the pupil with strong light is also increased.

  Next, a control signal for turning off the trigger switches 102d and 112d is sent via the input / output port I / O to turn off the trigger switches 102d and 112d (step S37).

  Next, a control signal for turning off the charging switches 102a and 112a is sent via the input / output port I / O to turn off the charging switches 102a and 112a (step S38), and this processing routine is finished. Note that when the voltages of the discharge capacitors 102c and 112c and the trigger capacitor drop due to the discharge, the discharge naturally stops, and these capacitors are charged again if the charge switches 102a and 112a are on.

  As described above, according to the present embodiment, the control circuit 105 is darker than the predetermined dark state and should be repulsed by the signal from the optical sensor 13 and the signal from the proximity sensor 14. Only when the birds and beasts approach each other, flashlights are simultaneously generated from the two xenon flash lamps 100 and 110 arranged on both sides obliquely forward. Nocturnal birds and wild animals such as wild boars and deer are exposed to light or sound in a bright environment, or repeatedly generate light or sound at regular intervals even in a dark environment. At that point, you will be surprised and repelled, but if you repeat this many times, the repelling effect will fade. On the other hand, in this embodiment, when the surrounding environment is bright, nothing is done and the surrounding environment is darker than a predetermined dark state and only when the birds and beasts are approaching, the birds and beasts are exposed to light from both sides diagonally forward. Even if it is not facing the front, strong light is reliably applied to the eye with the pupil wide open. As a result, a tremendous shock can be given to birds and beasts. This shock is so large that it cannot be easily recovered in a short time. Once repelled, the birds and beasts will not appear again, and the repelling effect will remain intact for a long time. Moreover, since it does not generate a loud sound, it does not disturb the surrounding environment at night.

  The electrical configuration of the present embodiment described above is merely an example, and it is needless to say that the present embodiment can be configured in various other forms.

  Further, in the fourth embodiment described above, two xenon flash lamps are arranged on both sides obliquely forward, but flashlights are simultaneously incident on the birds and beasts from three or more xenon flash lamps at different angles. You may comprise as follows. Further, the second embodiment described with reference to FIGS. 4 to 6, the third embodiment described with reference to FIGS. 7 to 9, and / or the fourth embodiment described with reference to FIGS. It is good also as a structure combined with the form.

  FIG. 13 schematically shows the overall configuration of the bird and animal hunting apparatus according to the fifth embodiment of the present invention, and FIG. 14 schematically shows the electrical configuration of the bird and animal hunting apparatus.

  As apparent from FIGS. 13 and 14, this embodiment has a configuration having a single xenon flash lamp 10 in the first embodiment, but two xenons in which one or both are selectively driven are used. The flash lamps 130 and 140 and the reflectors 131 and 141 for increasing the brightness of the flash light and giving directivity to the flash light are provided, and two lamp driving circuits for driving the xenon flash lamps 130 and 140, respectively. 132 and 142, a control circuit 135 is provided instead of the control circuit 15, and an optical sensor 133 is provided instead of the optical sensor 13. Other configurations in the fifth embodiment are substantially the same as those in the first embodiment, and therefore, the same constituent elements are represented by using the same reference numerals.

  As shown in FIGS. 13 and 14, the two xenon flash lamps 130 and 140 have the same irradiation direction, and the direction of the flash and the direction in which the proximity sensor 14 detects the approach of the birds and beasts are substantially the same direction. It is comprised so that it may become. If the direction is the same, a flash will be emitted in the direction in which the birds and beasts approach, and the flash will be directed toward the front of the birds and beasts.

  In the present embodiment, the optical sensor 133 uses, for example, a CdS optical sensor. This CdS optical sensor is an optical sensor that uses cadmium sulfide (CdS), which is a compound semiconductor. By applying light, free electrons proportional to the amount of light are generated in the semiconductor, and the current is changed to change the resistance value. Reduce. In the present embodiment, a detection signal having a value corresponding to the brightness is output from the optical sensor 133 in this way. Instead of the CdS optical sensor, an optical sensor using a CdSe cell, a PbS cell, another photoresistor, a photodiode, a phototransistor, a photo IC, a solar cell, or the like may be used.

  The power supply circuit 16 is configured to be able to supply a DC voltage to the two lamp driving circuits 132 and 142 and the control circuit 135. In the present embodiment, for example, a rechargeable vehicle battery is used. Instead of the battery, a commercial power source and an AC / DC converter that converts the commercial power source voltage into a DC voltage may be used. Of course, the solar battery panel may be used to charge the battery with sunlight in the daytime.

  The lamp driving circuits 132 and 142 are circuits for driving the xenon flash lamps 130 and 140, respectively. As shown in FIG. 14, the lamp driving circuits 132 and 142 include charging switches 132a and 142a, DC-DC converters 132b and 142b for boosting a low battery voltage to a high voltage, discharge capacitors 132c and 142c, , Trigger circuits 132e and 142e having trigger switches 132d and 142d, respectively.

  In this embodiment, as shown in FIG. 14, the control circuit 135 receives detection signals from the optical sensor 133 and the proximity sensor 14, and controls the charging switches 132a and 142a and the trigger switches 132d and 142d. It is comprised from the microcomputer which outputs. This microcomputer has an MPU that performs arithmetic processing, a ROM that stores processing programs and data, a RAM that temporarily stores information and results necessary for processing, and an input / output device that performs input / output with external devices. It is a general one including an output port I / O and the like. Needless to say, the function of the control circuit 135 may be achieved by a hardware circuit such as a comparator or a logic circuit.

  FIG. 15 illustrates the control operation of the control circuit 135 in the fifth embodiment. In the present embodiment, the processing routine shown in the figure is executed at regular intervals.

  In this processing routine, first, a signal from the optical sensor 133 is detected via the input / output port I / O (step S41).

  Next, it is determined from this detection signal whether or not the surrounding environment is darker than a predetermined first dark state (step S42). This first dark state is, for example, a low illuminance state after sunset and a dusk state. Since the optical sensor 133 which is a CdS optical sensor outputs a detection signal having a value corresponding to the darkness, the detection signal is A / D converted and then compared with the first threshold corresponding to the first darkness state. Judgment is made.

  When it is determined that the surrounding environment is not darker than the predetermined first dark state (in the case of NO), the process proceeds to step S49, and both the charge switches 132a and 142a of the lamp drive circuits 132 and 142 are turned off. This processing routine is finished as it is. On the other hand, when it is determined that the surrounding environment is darker than the predetermined first dark state (in the case of YES), a control signal for turning on both charging switches 132a and 142a is sent via the input / output port I / O. Are sent to the charging switches 132a and 142a, respectively (step S43).

  In the lamp driving circuits 132 and 142, when the charging switches 132a and 142a are turned on, the DC-DC converters 132b and 142b operate, and the discharge capacitors 132c and 142c are charged, respectively. At the same time, the trigger capacitors of the trigger circuits 132e and 142e are charged through the high resistance, respectively.

  Next, a signal from the proximity sensor 14 is detected via the input / output port I / O (step S44).

  Next, it is determined from this detection signal whether or not a nocturnal bird or a wild animal such as a wild boar, a monkey or a deer has approached (step S45). When the proximity sensor 14 which is a pyroelectric infrared sensor has a comparison function, a binary signal indicating whether or not the proximity sensor 14 is approaching is input from the proximity sensor 14, so that the signal is directly used as a determination signal. On the other hand, when the proximity sensor 14 does not have such a comparison function and outputs a detection signal having a value corresponding to the approach distance, the detection signal is A / D converted and then compared with a threshold value. Judgment is made.

  When it is determined that the birds and beasts are not approaching (in the case of NO), the process returns to step S44, and the processing of this signal detection (step S44) and determination (step S45) is repeated. On the other hand, if it is determined that the birds and beasts have approached (in the case of YES), it is determined from the detection signal of the optical sensor 133 whether or not the surrounding environment has become darker than a predetermined second dark state (step S46). This second dark state is a state that is darker than the first dark state, for example, a state in which the light intensity is considerably low after sunset and after dusk. Since the optical sensor 133 which is a CdS optical sensor outputs a detection signal having a value corresponding to the darkness, the detection signal is A / D converted and then compared with a second threshold value corresponding to the second darkness state. Judgment is made.

  When it is determined that the ambient environment is not darker than the predetermined second darkness state (in the case of NO), the process proceeds to step S47 to control to turn on both trigger switches 132d and 142d of the lamp drive circuits 132 and 142 A signal is sent to the trigger switches 132d and 142d via the input / output port I / O (step S47).

  In the lamp drive circuits 132 and 142, when the trigger switches 132d and 142d are turned on, the trigger capacitor is discharged and the electric charge flows through the primary winding of the trigger transformer. A pulse voltage of V is generated. This pulse voltage is applied to trigger electrodes 130a and 140a adjacent to the entire tubes of the xenon flash lamps 130 and 140, respectively, and the high-voltage electric field is transmitted into the tube through the tube wall of the lamp to ionize the xenon gas and reduce it. Excites the discharge. As a result, an avalanche occurs and the electric charges of the discharge capacitors 132c and 142c are discharged all at once, and arc discharge is started between the discharge electrodes (anode and cathode), respectively. When the arc discharge starts, the inside of the tube is almost short-circuited, so that the electric charges of the discharge capacitors 132c and 142c are instantaneously discharged, and flashes are simultaneously generated from the xenon flash lamps 130 and 140.

  This flash is generated simultaneously from the two xenon flash lamps 130 and 140 directed in the same direction and has directivity, so that a very strong flash is applied to the approaching bird from the front. The Rukoto. For this reason, even if the surrounding environment is not completely dark due to dusk or the like, a strong flash is applied from the front of the eyes of the birds and beasts, and the pupil is irradiated with strong light.

  Next, a control signal for turning off both trigger switches 132d and 142d is sent via the input / output port I / O to turn off the trigger switches 132d and 142d, respectively (step S48).

  Next, a control signal for turning off both charging switches 132a and 142a is sent via the input / output port I / O to turn off the charging switches 132a and 142a (step S49), and the processing routine is ended. Note that when the voltages of the discharge capacitors 132c and 142c and the trigger capacitor drop due to the discharge, the discharge naturally stops, and these capacitors are charged again if the charge switches 132a and 142a are on.

  On the other hand, if it is determined in step S46 that the surrounding environment is darker than the predetermined second dark state (in the case of YES), the process proceeds to step S50, and one trigger switch 132d of only one lamp driving circuit 132 is turned on. A control signal to be turned on is sent to the trigger switch 132d via the input / output port I / O (step S50).

  In the lamp driving circuit 132, when the trigger switch 132d is turned on, the trigger capacitor is discharged and the electric charge flows through the primary winding of the trigger transformer. Therefore, a pulse voltage of several thousand volts is applied to the secondary winding of the trigger transformer. Will occur. This pulse voltage is applied to the trigger electrode 130a adjacent to the entire tube of the xenon flash lamp 130, and the high-voltage electric field is transmitted into the tube through the tube wall of the lamp to ionize the xenon gas and excite a small discharge. As a result, avalanche occurs, and the electric charge of the discharge capacitor 132c is discharged at once, and arc discharge is started between the discharge electrodes (anode and cathode). When the arc discharge starts, the inside of the tube is almost short-circuited, so that the electric charge of the discharge capacitor 132c is instantaneously discharged, and a flash is generated from the xenon flash lamp 130.

  This flash is generated only from one of the xenon flash lamps 130, but since the surrounding environment is very dark, a sufficiently strong flash is applied to the approaching bird from the front. For this reason, a strong flash is applied from the front of the bird's eye, and the pupil is irradiated with strong light.

  Next, a control signal for turning off the trigger switch 132d is sent via the input / output port I / O to turn off the trigger switch 132d (step S51).

  Next, a control signal for turning off both charging switches 132a and 142a is sent via the input / output port I / O to turn off the charging switches 132a and 142a (step S49), and the processing routine is ended. In addition, when the voltage of the discharge capacitor 132c and the trigger capacitor decreases due to the discharge, the discharge naturally stops, and these capacitors are charged again if the charge switch 132a is on.

  As described above, according to the present embodiment, the signal from the optical sensor 133 and the signal from the proximity sensor 14 cause the control circuit 135 to be darker than the first dark state in which the surrounding environment is predetermined. Only when the birds and beasts to be repulsed approach, a flash is generated from both or one of the two xenon flash lamps 130 and 140. Furthermore, in that case, when it is darker than the second dark state, which is darker than the first dark state, a flash is generated only from one xenon flash lamp 130, and when it is equal to or brighter than the second dark state Generates flash from both xenon flash lamps 130 and 140. Nocturnal birds and wild animals such as wild boars and deer are exposed to light or sound in a bright environment, or repeatedly generate light or sound at regular intervals even in a dark environment. At that point, you will be surprised and repelled, but if you repeat this many times, the repelling effect will fade. On the other hand, in this embodiment, when the surrounding environment is bright, nothing is done, and the surrounding environment is darker than the first dark state set in advance and is the same as or brighter than the second dark state, and the birds and beasts are approaching Only two Xenon flash lamps 130 and 140 are flashed at the same time, and only one Xenon flash lamp 130 is flashed only when the surrounding environment is darker than the predetermined second dark state and a bird and beast approach. ing. For this reason, since a flash corresponding to the dark state is applied, the flash is applied to the eyes with the pupils of the birds and beasts wide open. As a result, a tremendous shock can be given to birds and beasts. This shock is so large that it cannot be easily recovered in a short time. Once repelled, the birds and beasts will not appear again, and the repelling effect will remain intact for a long time. Moreover, since it does not generate a loud sound, it does not disturb the surrounding environment at night.

  The electrical configuration of the present embodiment described above is merely an example, and it is needless to say that the present embodiment can be configured in various other forms.

  In the fifth embodiment described above, both or one of the two xenon flash lamps are energized in accordance with the dark state of the surrounding environment to emit a flash. All or part of the xenon flash lamp may be energized according to the darkness of the surrounding environment. Further, the second embodiment described with reference to FIGS. 4 to 6, the third embodiment described with reference to FIGS. 7 to 9, and / or the fourth embodiment described with reference to FIGS. It is good also as a structure combined with the form.

  FIG. 16 schematically shows the overall configuration of a birds and animals hunting apparatus according to a sixth embodiment of the present invention, and FIG. 17 schematically shows the electrical configuration of the birds and animals hunting apparatus.

  As apparent from FIGS. 16 and 17, the first embodiment has a single xenon flash lamp 10, but in this embodiment, two xenon flash lamps that are sequentially driven with a time delay. 160 and 170, and reflectors 161 and 171 for increasing the brightness of the flash and giving directivity to the flash, and two lamp driving circuits 162 and 160 for driving the xenon flash lamps 160 and 170, respectively. 172, a control circuit 165 is provided instead of the control circuit 15, and an optical sensor 163 is provided instead of the optical sensor 13. Other configurations in the sixth embodiment are substantially the same as those in the first embodiment, and therefore, the same constituent elements are represented by using the same reference numerals.

  As shown in FIGS. 16 and 17, the two xenon flash lamps 160 and 170 have the same irradiation direction, and the direction of the flash and the direction in which the proximity sensor 14 detects the approach of the birds and beasts are substantially the same direction. It is comprised so that it may become. If the direction is the same, a flash will be emitted in the direction in which the birds and beasts approach, and the flash will be directed toward the front of the birds and beasts.

  In this embodiment, the optical sensor 163 uses, for example, a CdS optical sensor. This CdS optical sensor is an optical sensor that uses cadmium sulfide (CdS), which is a compound semiconductor. By applying light, free electrons proportional to the amount of light are generated in the semiconductor, and the current is changed to change the resistance value. Reduce. In this embodiment, a detection signal having a value corresponding to the brightness is output from the optical sensor 163 in this way. Instead of the CdS optical sensor, an optical sensor using a CdSe cell, a PbS cell, another photoresistor, a photodiode, a phototransistor, a photo IC, a solar cell, or the like may be used.

  The power supply circuit 16 is configured to be able to supply a DC voltage to the two lamp driving circuits 162 and 172 and the control circuit 165, and in the present embodiment, a rechargeable vehicle battery, for example, is used. Instead of the battery, a commercial power source and an AC / DC converter that converts the commercial power source voltage into a DC voltage may be used. Of course, the solar battery panel may be used to charge the battery with sunlight in the daytime.

  The lamp driving circuits 162 and 172 are circuits for driving the xenon flash lamps 160 and 170, respectively. As shown in FIG. 17, the lamp driving circuits 162 and 172 include charging switches 162a and 172a, DC-DC converters 162b and 172b for boosting a low battery voltage to a high voltage, discharge capacitors 162c and 172c, , Trigger circuits 162e and 172e having trigger switches 162d and 172d, respectively.

  In this embodiment, as shown in FIG. 17, the control circuit 165 receives detection signals from the optical sensor 163 and the proximity sensor 14, and controls the charging switches 162a and 172a and the trigger switches 162d and 172d. It is comprised from the microcomputer which outputs. This microcomputer has an MPU that performs arithmetic processing, a ROM that stores processing programs and data, a RAM that temporarily stores information and results necessary for processing, and an input / output device that performs input / output with external devices. It is a general one including an output port I / O and the like. Needless to say, the function of the control circuit 165 may be achieved by a hardware circuit such as a comparator or a logic circuit.

  FIG. 18 illustrates the control operation of the control circuit 165 in the sixth embodiment. In the present embodiment, the processing routine shown in the figure is executed at regular intervals.

  In this processing routine, first, a signal from the optical sensor 163 is detected via the input / output port I / O (step S61).

  Next, it is determined from this detection signal whether or not the surrounding environment has become darker than a predetermined dark state (step S62). When the optical sensor 163 that is a CdS optical sensor has a comparison function, a binary signal indicating whether the surrounding environment is darker than a predetermined dark state is input from the optical sensor 163. The signal becomes the discrimination signal as it is. On the other hand, when the optical sensor 163 does not have such a comparison function and outputs a detection signal having a value corresponding to the darkness, the detection signal is A / D converted and then compared with a threshold value. Judgment is made.

  If it is determined that the surrounding environment is not darker than the predetermined dark state (in the case of NO), the process proceeds to step S61, and both the charge switches 162a and 172a of the lamp drive circuits 162 and 172 are left in the OFF state. The processing routine ends. On the other hand, when it is determined that the surrounding environment is darker than a predetermined dark state (in the case of YES), control signals for turning on both charging switches 162a and 172a are charged via the input / output port I / O. Each is sent to the switches 162a and 172a (step S63).

  In the lamp driving circuits 162 and 172, when the charging switches 162a and 172a are turned on, the DC-DC converters 162b and 172b operate, and the discharge capacitors 162c and 172c are charged, respectively. At the same time, the trigger capacitors of the trigger circuits 162e and 172e are charged through high resistances, respectively.

  Next, a signal from the proximity sensor 14 is detected via the input / output port I / O (step S64).

  Next, it is determined from this detection signal whether or not a nocturnal bird or a wild animal such as a wild boar, a monkey or a deer has approached (step S65). When the proximity sensor 14 which is a pyroelectric infrared sensor has a comparison function, a binary signal indicating whether or not the proximity sensor 14 is approaching is input from the proximity sensor 14, so that the signal is directly used as a determination signal. On the other hand, when the proximity sensor 14 does not have such a comparison function and outputs a detection signal having a value corresponding to the approach distance, the detection signal is A / D converted and then compared with a threshold value. Judgment is made.

  When it is determined that the birds and beasts are not approaching (in the case of NO), the process returns to step S54, and the processing of this signal detection (step S64) and determination (step S65) is repeated. On the other hand, when it is determined that a bird or beast has approached (in the case of YES), a control signal for turning on the trigger switch 162d of one lamp driving circuit 162 is sent to the trigger switch 162d via the input / output port I / O ( Step S66).

  In the lamp driving circuit 162, when the trigger switch 162d is turned on, the trigger capacitor is discharged and the electric charge flows through the primary winding of the trigger transformer. Therefore, a pulse voltage of several thousand volts is applied to the secondary winding of the trigger transformer. Will occur. This pulse voltage is applied to the trigger electrode 160a close to the entire tube of the xenon flash lamp 160, and the high-voltage electric field is transmitted into the tube through the tube wall of the lamp to ionize the xenon gas and excite a small discharge. As a result, avalanche occurs, and the electric charge of the discharge capacitor 162c is discharged at once, and arc discharge is started between the discharge electrodes (anode and cathode). When the arc discharge starts, the inside of the tube is almost short-circuited, so that the electric charge of the discharge capacitor 162c is instantaneously discharged, and a flash is generated from the xenon flash lamp 160.

  Since this flash has directivity and is directed toward the bird and animal approaching, the bird and animal are exposed to strong light from the front of their eyes. In addition, since the surrounding environment is darker than the predetermined dark state and the target to be repulsed approaches, the flash is applied from the front of the eyes, so that strong light is applied to the birds and beasts with the pupil wide open. The Rukoto.

  Next, a control signal for turning off the one trigger switch 162d is sent via the input / output port I / O to turn off the one trigger switch 162d (step S67).

  Thereafter, it is determined whether or not a predetermined set delay time has elapsed from the one trigger switch 162d being turned on, and hence the flash from one xenon flash lamp 160 (step S68). If the set delay time has elapsed (YES) ) Only, a control signal for turning on the trigger switch 172d of the other lamp driving circuit 172 is sent to the trigger switch 172d via the input / output port I / O (step S69).

  In the lamp driving circuit 172, when the trigger switch 172d is turned on, the trigger capacitor is discharged and the electric charge flows through the primary winding of the trigger transformer. Therefore, a pulse voltage of several thousand volts is applied to the secondary winding of the trigger transformer. Will occur. This pulse voltage is applied to the trigger electrode 170a adjacent to the entire tube of the xenon flash lamp 170, and the high-voltage electric field is transmitted into the tube through the tube wall of the lamp to ionize the xenon gas and excite a small discharge. As a result, an avalanche occurs and the electric charge of the discharge capacitor 172c is discharged at once, and arc discharge starts between the discharge electrodes (anode and cathode). When the arc discharge starts, the inside of the tube is almost short-circuited, so that the electric charge of the discharge capacitor 172c is instantaneously discharged, and flash light is generated from the xenon flash lamp 170.

  Since this flash also has directivity and is directed toward the approaching bird and beast, the bird and animal are exposed to strong light from the front of their eyes. Moreover, since the flash is applied after a certain delay time from the first flash, the shock given to the birds and beasts is very large, and the repelling effect is greatly enhanced.

  Next, a control signal for turning off the other trigger switch 172d is sent via the input / output port I / O to turn off the other trigger switch 172d (step S70).

  Next, a control signal for turning off both charging switches 162a and 172a is sent via the input / output port I / O to turn off the charging switches 162a and 172a (step S71), and this processing routine is ended. Note that when the voltages of the discharge capacitors 162c and 172c and the trigger capacitor drop due to the discharge, the discharge stops spontaneously, and these capacitors are charged again if the charge switches 162a and 172a are on.

  As described above, according to the present embodiment, the control circuit 165 is darker than the predetermined dark state and should be repulsed by the signal from the optical sensor 163 and the signal from the proximity sensor 14. Only when the birds and beasts approach, a flash is first generated from only one xenon flash lamp 160. Further, after the set delay time, a flash is also generated from the other xenon flash lamp 170. Nocturnal birds and wild animals such as wild boars and deer are exposed to light or sound in a bright environment, or repeatedly generate light or sound at regular intervals even in a dark environment. At that point, you will be surprised and repelled, but if you repeat this many times, the repelling effect will fade. On the other hand, in this embodiment, when the surrounding environment is bright, nothing is done, and only when the surrounding environment is darker than the predetermined dark state and the birds and beasts are approaching, it is exposed to two flashes with a certain delay time. Yes. For this reason, a very big shock can be given to birds and beasts. This shock is so large that it cannot be easily recovered in a short time. Once repelled, the birds and beasts will not appear again, and the repelling effect will remain intact for a long time. Moreover, since it does not generate a loud sound, it does not disturb the surrounding environment at night.

  The electrical configuration of the present embodiment described above is merely an example, and it is needless to say that the present embodiment can be configured in various other forms.

  Further, in the sixth embodiment described above, two xenon flash lamps are sequentially energized with a set delay time to emit a flash, but one xenon flash lamp is set. Of course, it may be configured to energize and emit a flash with a delay time, or it may be configured to sequentially activate three or more xenon flash lamps with a set delay time. good. Further, the delay time may be variably set. Furthermore, the second embodiment described with reference to FIGS. 4 to 6, the third embodiment described with reference to FIGS. 7 to 9, and / or the fourth embodiment described with reference to FIGS. It is good also as a structure combined with embodiment.

  FIG. 19 schematically shows the overall configuration of a bird and animal hunting apparatus according to a seventh embodiment of the present invention, and FIG. 20 schematically shows the electrical configuration of the bird and animal hunting apparatus.

  As apparent from FIGS. 19 and 20, in the first to sixth embodiments, the xenon flash lamp, the proximity sensor, the optical sensor, the lamp driving circuit, the power supply circuit, and the control circuit are integrated to form a main body. However, in the present embodiment, the xenon flash lamps 1901 to 1903, the proximity sensors 1941 to 1943, and the first sensors are separated from the main unit including the optical sensor 193, the first lamp driving circuit 1920, the power supply circuit 196, and the control circuit 195. There are a plurality of light generating units comprising two lamp driving circuits 1921 to 1923, and each light generating unit is configured to detect the proximity of a bird and beast and emit light. That is, in this embodiment, a plurality of light generating units respectively disposed at appropriate positions for driving away the birds and beasts are electrically connected to the single main unit and controlled. In the present embodiment, only three light generation units are provided, but it is needless to say that two or more light generation units may be provided.

  The optical sensor 193 is provided in the main body unit. In the present embodiment, for example, a CdS optical sensor is used. This CdS optical sensor is an optical sensor that uses cadmium sulfide (CdS), which is a compound semiconductor. By applying light, free electrons proportional to the amount of light are generated in the semiconductor, and the current is changed to change the resistance value. Reduce. In the present embodiment, a detection signal having a value corresponding to the brightness is output from the optical sensor 193 in this way. Instead of the CdS optical sensor, an optical sensor using a CdSe cell, a PbS cell, another photoresistor, a photodiode, a phototransistor, a photo IC, a solar cell, or the like may be used.

  The power supply circuit 196 is provided in the main unit, and is configured to be able to supply a DC voltage to the first lamp driving circuit 1920 and the control circuit 195. In the present embodiment, for example, a rechargeable vehicle battery Is used. Instead of the battery, a commercial power source and an AC / DC converter that converts the commercial power source voltage into a DC voltage may be used. Of course, the solar battery panel may be used to charge the battery with sunlight in the daytime.

  The first lamp driving circuit 1920 and the second lamp driving circuits 1921 to 1923 are circuits for driving the xenon flash lamps 1901 to 1903, respectively. As shown in FIG. 20, the first lamp driving circuit 1920 includes a charging switch 1920a and a DC-DC converter 1920b that boosts a low battery voltage to a high voltage. Yes.

  The second lamp driving circuits 1921 to 1923 are provided in the light generation units, respectively, and include discharge capacitors 1921c to 1923c and trigger circuits 1921e to 1923e having trigger switches 1921d to 1923d, respectively.

  The control circuit 195 is provided in the main unit, and in this embodiment, as shown in FIG. 20, the detection signal from the optical sensor 193 provided in the main unit and the proximity provided in the light generation unit, respectively. The microcomputer includes a microcomputer that receives detection signals from the sensors 1941 to 1943 and outputs control signals for controlling the charging switch 1920a and the trigger switches 1921d to 1923d. This microcomputer has an MPU that performs arithmetic processing, a ROM that stores processing programs and data, a RAM that temporarily stores information and results necessary for processing, and an input / output device that performs input / output with external devices. It is a general one including an output port I / O and the like. Needless to say, the function of the control circuit 195 may be achieved by a hardware circuit such as a comparator or a logic circuit.

  FIG. 21 illustrates the control operation of the control circuit 195 in the seventh embodiment. In the present embodiment, the processing routine shown in the figure is executed at regular intervals.

  In this processing routine, first, a signal from the optical sensor 193 is detected via the input / output port I / O (step S81).

  Next, it is determined from this detection signal whether or not the surrounding environment has become darker than a predetermined dark state (step S82). When the optical sensor 193, which is a CdS optical sensor, has a comparison function, a binary signal indicating whether the surrounding environment has become darker than a predetermined dark state is input from the optical sensor 193. The signal becomes the discrimination signal as it is. On the other hand, when the optical sensor 193 does not have such a comparison function and outputs a detection signal having a value corresponding to the darkness, the detection signal is A / D converted and then compared with a threshold value. Judgment is made.

  If it is determined that the surrounding environment is not darker than the predetermined dark state (in the case of NO), the process proceeds to step S81, and the charge switch 1920a of the first lamp drive circuit 1920 is left in the OFF state, and this processing routine is performed. finish. On the other hand, when it is determined that the surrounding environment is darker than a predetermined dark state (in the case of YES), a control signal for turning on charging switch 1920a is sent to charging switch 1920a via input / output port I / O. (Step S83).

  In the first lamp driving circuit 1920, when the charging switch 1920a is turned on, the DC-DC converter 1920b operates to charge the discharge capacitors 1921c to 1923c in the second lamp driving circuits 1921 to 1923, respectively. At the same time, the trigger capacitors of the trigger circuits 1921e to 1923e are charged through high resistances.

  Next, signals from the proximity sensors 1941 to 1943 in the second lamp driving circuits 1921 to 1923 of the light generation unit are detected via the input / output port I / O (step S84).

  Next, it is determined from this detection signal whether or not a nocturnal bird or a wild animal such as a wild boar, a monkey or a deer has approached (step S85). When the proximity sensors 1941 to 1943 that are pyroelectric infrared sensors have a comparison function, a binary signal indicating whether or not the proximity sensors 1941 to 1943 are approached is input from one or more of these proximity sensors 1941 to 1943. Therefore, the signal becomes the discrimination signal as it is. On the other hand, when the proximity sensors 1941 to 1943 do not have such a comparison function and output a detection signal having a value corresponding to the approach distance, the detection signal is A / D converted and then compared with a threshold value. Judgment is made.

  When it is determined that the birds and beasts are not approaching (in the case of NO), the process returns to step S84, and the processing of this signal detection (step S84) and determination (step S85) is repeated. On the other hand, when it is determined that a bird or animal has approached (in the case of YES), a control signal for turning on the trigger switch 1921d, 1922d or 1923d of the second lamp driving circuit 1921, 1922 or 1923 in the corresponding light generation unit is input. The data is sent to the corresponding trigger switch 1921d, 1922d or 1923d via the output port I / O (step S86).

  In the second lamp driving circuit 1921, 1922, or 1923, when the trigger switch 1921d, 1922d, or 1923d is turned on, the trigger capacitor is discharged and the charge flows through the primary winding of the trigger transformer. A pulse voltage of several thousand volts is generated in the secondary winding. This pulse voltage is applied to the trigger electrode 1901a, 1902a or 1903a adjacent to the entire tube of the xenon flash lamp 1901, 1902 or 1903, and its high-voltage electric field is transmitted into the tube via the tube wall of the lamp to ionize the xenon gas. And a small discharge is excited. As a result, an avalanche occurs, and the electric charges of the discharge capacitors 1921c, 1922c, or 1923c are discharged all at once, and arc discharge starts between the discharge electrodes (anode and cathode). When the arc discharge starts, the inside of the tube is almost short-circuited, so that the electric charge of the discharge capacitor 1921c, 1922c or 1923c is instantaneously discharged, and flashing is generated from the corresponding xenon flash lamp 1901, 1902 or 1903.

  Since this flash has directivity and is directed toward the bird and animal approaching, the bird and animal are exposed to strong light from the front of their eyes. In addition, since the surrounding environment is darker than the predetermined dark state and the target to be repulsed approaches, the flash is applied from the front of the eyes, so that strong light is applied to the birds and beasts with the pupil wide open. The Rukoto.

  Next, a control signal for turning off the trigger switch 1921d, 1922d, or 1923d is sent via the input / output port I / O to turn off the trigger switch 1921d, 1922d, or 1923d (step S87).

  Thereafter, a control signal for turning off the charge switch 1920a is sent via the input / output port I / O to turn off the charge switch 1920a (step S88), and this processing routine is ended. Note that when the voltage of the discharge capacitors 1921c, 1922c, or 1923c and the trigger capacitor drops due to the discharge, the discharge stops spontaneously, and these capacitors are charged again if the charge switch 1921c, 1922c, or 1923c is on.

  As described above, according to the present embodiment, the control circuit 195 is based on the signal from the optical sensor 193 provided in the main unit and the signals from the proximity sensors 1941 to 1943 provided in the light generation unit. Flash light is generated from the xenon flash lamp 1901, 1902 or 1903 of the corresponding light generation unit only when the surrounding environment is darker than a predetermined dark state and the birds and beasts to be repulsed approach. Nocturnal birds and wild animals such as wild boars and deer are exposed to light or sound in a bright environment, or repeatedly generate light or sound at regular intervals even in a dark environment. At that point, you will be surprised and repelled, but if you repeat this many times, the repelling effect will fade. On the other hand, in the present embodiment, nothing is done when the surrounding environment is bright, and only when the surrounding environment is darker than the predetermined dark state and the birds and beasts are approaching, the flash is applied. For this reason, a very big shock can be given to birds and beasts. This shock is so large that it cannot be easily recovered in a short time. Once repelled, the birds and beasts will not appear again, and the repelling effect will remain intact for a long time. Moreover, since it does not generate a loud sound, it does not disturb the surrounding environment at night.

  The electrical configuration of the present embodiment described above is merely an example, and it is needless to say that the present embodiment can be configured in various other forms.

  4 to 6, the third embodiment described in FIGS. 7 to 9, the fourth embodiment described in FIGS. 10 to 12, and FIGS. 13 to 15. The fifth embodiment described and / or the sixth embodiment described with reference to FIGS. 16 to 18 may be combined with this embodiment.

  FIG. 22 schematically shows the overall configuration of the bird and animal hunting apparatus according to the eighth embodiment of the present invention, and FIG. 23 schematically shows the electrical configuration of the LED drive circuit according to this embodiment.

  In the first to seventh embodiments, a xenon flash lamp is used as a flash light source, but as is apparent from FIG. 22, one or a plurality of high-intensity LEDs 221 are used in this embodiment. Furthermore, in this embodiment, an optical switch 223 in which a switch is combined with an optical sensor is used. For this reason, in this embodiment, the drive circuit of the light source is simplified, and the control is further simplified.

  The high-intensity LED 221 is connected to an LED drive circuit 222, and a proximity sensor 224 is connected to the LED drive circuit 222 so that a detection signal thereof is input. Further, the LED drive circuit 222 is connected to a power supply circuit 226 via an optical switch 223 and is configured to receive power supply.

  In this embodiment, the optical switch 223 uses, for example, a combination of a CdS optical sensor and a switch. This CdS optical sensor is an optical sensor that uses cadmium sulfide (CdS), which is a compound semiconductor. By applying light, free electrons proportional to the amount of light are generated in the semiconductor, and the current is changed to change the resistance value. Reduce. In this embodiment, the switch is turned on / off by the detection signal having a value corresponding to the brightness as described above. Instead of the CdS optical sensor, an optical sensor using a CdSe cell, a PbS cell, another photoresistor, a photodiode, a phototransistor, a photo IC, a solar cell, or the like may be used.

  The power supply circuit 226 is configured to be able to supply a DC voltage to the LED drive circuit 222. In the present embodiment, a rechargeable battery, for example, is used. Instead of the battery, a commercial power source and an AC / DC converter that converts the commercial power source voltage into a DC voltage may be used. Of course, the solar battery panel may be used to charge the battery with sunlight in the daytime.

  The LED drive circuit 222 is a circuit for driving one or a plurality of high-intensity LEDs 221 in a flash manner. As shown in FIG. 23, the LED driving circuit 222 for driving the flash includes, for example, a commercially available constant current type DC-DC converter 222a, an inductor 222b, a Schottky diode 222c, and a capacitor 222d. An inductor 222b, a Schottky diode 222c, and a capacitor 222d are connected in series between the output of the DC converter 222a and the ground, and the proximity sensor 224 turns on and off between the connection point of the inductor 222b and the Schottky diode 222c and the ground. The transistor 222e to be controlled is inserted, and a high brightness LED 221 is connected in parallel to the capacitor 222d. The base of the transistor 222e is configured to be applied with a binary signal indicating whether or not the proximity sensor 224, which is a pyroelectric infrared sensor, has been approached. The transistor 222e is turned on by a signal output from the H.224.

  Hereinafter, the operation of the bird and animal hunting apparatus in the present embodiment will be described.

  The optical switch 223 is turned off when the surrounding environment is not darker than a predetermined dark state, and is turned on when the surrounding environment is darker than the predetermined dark state. Is supplied with power.

  In the LED drive circuit 222, the transistor 222 e is turned on by a signal output from the proximity sensor 224 when the bird is not approaching. For this reason, when power is supplied, the current from the DC-DC converter 222a flows to the inductance 222b. When the proximity sensor 224 detects the approach of a nocturnal bird or a wild beast such as a wild boar, a monkey or a deer, and the transistor 222e is turned off, the energy stored in the inductance 222b is released, and the Schottky diode 222c is discharged. And stored in the capacitor 222d. When the terminal voltage of the capacitor 222d becomes a value sufficient for energizing the high-intensity LED 221, discharge occurs from the capacitor 222d, the high-intensity LED 221 is turned on instantaneously, and flashing occurs.

  Since this flash has directivity and is directed toward the bird and animal approaching, the bird and animal are exposed to strong light from the front of their eyes. In addition, since the surrounding environment is darker than the predetermined dark state and the target to be repulsed approaches, the flash is applied from the front of the eyes, so that strong light is applied to the birds and beasts with the pupil wide open. The Rukoto.

  As described above, according to the present embodiment, the LED drive circuit 222 should be repelled by the operation of the optical switch 223 and the signal from the proximity sensor 224, and the surrounding environment is darker than the predetermined dark state. Only when the birds and beasts approach, the high-intensity LED 221 is flashed to generate a flash. Nocturnal birds and wild animals such as wild boars and deer are exposed to light or sound in a bright environment, or repeatedly generate light or sound at regular intervals even in a dark environment. At that point, you will be surprised and repelled, but if you repeat this many times, the repelling effect will fade. On the other hand, in the present embodiment, nothing is done when the surrounding environment is bright, and only when the surrounding environment is darker than the predetermined dark state and the birds and beasts are approaching, the flash is applied. For this reason, a very big shock can be given to birds and beasts. This shock is so large that it cannot be easily recovered in a short time. Once repelled, the birds and beasts will not appear again, and the repelling effect will remain intact for a long time. Moreover, since it does not generate a loud sound, it does not disturb the surrounding environment at night. In particular, in the present embodiment, since the LED is used as the light source, the driving circuit for the light source can be greatly simplified, and since it is not necessary to generate a high voltage, the driving circuit can be simplified. In addition, since a low-insulation wiring can be used, significant cost reduction can be achieved. In addition, the use of LEDs and the use of optical switches simplify the control, and the wiring from the power supply circuit to the LEDs and the proximity sensor may be a two-wire cable, which also greatly reduces costs. Can be planned.
