Description

  The present invention relates to a wildlife detection sensor device, for example, a wildlife detection sensor device that detects and records the behavior of wildlife in order to investigate the ecology of wildlife such as mammals and birds.

  In order to observe the ecology of wildlife such as mammals moving on the animal path and birds flying around in the forest, photographs are often taken using an automatic photography apparatus. Such an automatic photography apparatus is configured to emit a strobe light and automatically release the shutter of the camera when detecting the approach of wildlife at night or the like.

  However, wildlife suddenly exposed to the flash of strobe light, and until then had acted with their pupils open, they would become blind for a while and cause great fear. Moreover, the shutter sound of a camera etc. will give a load to wildlife. When taking a picture using such an automatic photography apparatus, wildlife hate this load and avoids the installation location of the camera due to the learning effect, which may make photography difficult.

Therefore, Japanese Patent Application Laid-Open No. 2002-139775 (Patent Document 1) provides a condition for allowing wildlife to frequently appear at the shooting location by allowing the time for eating food set in advance and the shooting conditions to be set as appropriate. There has been proposed a photography apparatus using an electronic circuit capable of performing the above.
JP 2002-139775 A

  On the other hand, in order to investigate the ecology of wildlife, not just photography of organisms, the frequency of wildlife that travels on the so-called beast road is being investigated, but there are many photos on the beast road etc. Arranging the photographing apparatus is very expensive. Also, taking a picture places a burden on wildlife as described above. In particular, the burden cannot be ignored in long-term continuous surveys.

  In addition, long-term continuous investigation of the effects of climate change and human activities on living organisms is called monitoring, which is also performed to verify the prediction assessment of environmental assessments. Therefore, the introduction of mechanical power for monitoring can contribute to the reduction of the research cost.

  Furthermore, in places where humans and wildlife share such as hiking trails, it is desirable to operate the device avoiding the time zone used by humans.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a wildlife detection sensor device that can detect wildlife and record the frequency of using a beast path or moving in a predetermined space in a forest together with information such as date and time. That is.

  The present invention is a wildlife detection sensor device for detecting and recording wildlife, comprising a sensor unit installed in a wildlife habitat, and an operation display unit that can be connected to and separated from the sensor unit, The sensor unit includes a sensor element that detects the movement of wildlife within a range of at least one of a wide angle and a narrow angle with respect to the front, timer means for measuring the current date and time, and the sensor element that controls the movement of the wildlife. Recording means for recording information indicating that a wildlife has approached together with the current date and time if the current date and time counted by the timer means is permitted in accordance with the detection. The display unit includes an operation unit for setting at least a time zone in the sensor unit, and display means for displaying information recorded in the recording means.

  For example, by setting a night time zone as the permitted time zone, it is possible to record the frequency of wild animals and wild birds using the animal path at night together with the date and time.

  In a preferred embodiment, a plurality of sensor units are provided, and at least one operation display unit is provided, and is configured to be electrically connected to and separated from the plurality of sensor units. If the operation display unit is provided in all of the sensor units, the cost increases. However, providing one operation display unit for a plurality of sensor units can reduce the cost.

  In a specific embodiment, the sensor element includes a first pyroelectric sensor that detects a change in infrared at a short distance at a wide angle, and a second pyroelectric sensor that detects a change in infrared at a long distance at a narrow angle. Including.

  Depending on the type of wildlife, the detection range of wildlife can be limited to an optimum range by combining a wide angle and a narrow angle, or only a wide angle or only a narrow angle.

  According to this invention, the sensor unit is installed in the wildlife habitat, and the change in the infrared rays accompanying the movement of the wildlife in the wide-angle or narrow-angle range with respect to the front is detected and recorded. The frequency of using the animal path can be recorded together with information such as the date and time, and automatic photographing can be minimized to reduce the burden on wildlife.

  FIG. 1 is an external view of a sensor unit 10 of a wildlife detection sensor device according to an embodiment of the present invention, (A) is an external perspective view seen from the front side, and (B) is an external view seen from the back side. It is a perspective view.

  In FIG. 1, the sensor unit 10 is installed in a wildlife habitat. For this purpose, the sensor unit includes a housing 1 having a waterproof structure so that it can withstand outdoor use. On the front surface of the housing 1, a first pyroelectric sensor 2 and a second pyroelectric sensor 3 as sensor elements and a reaction monitor LED (light emitting diode) 4 are arranged. The first pyroelectric sensor 2 is a wide-angle sensor, for example, a relatively wide angle range such as about 38 degrees, and an infrared ray associated with the movement of a wildlife approaching within a short distance, for example, a range of 5 m. The second pyroelectric sensor 3 is a narrow-angle sensor, for example, within a relatively narrow angle range such as about 5 degrees and is located at a long distance, for example, 30 m away. Detect organisms.

  In place of the pyroelectric sensors 2 and 3 that detect infrared fluctuations, an infrared or visible light emitting part and a light receiving part may be provided, and it may be detected that a wild creature blocks between them. Alternatively, a moving object may be detected using an active radar that utilizes the Doppler effect of radio waves or ultrasonic waves.

  In this embodiment, based on the detection signals of the first and second pyroelectric sensors 2 and 3, a mode for detecting only the narrow angle range and a mode for detecting the wide angle and narrow angle ranges in parallel. And can be switched. The reason why the wide angle and the narrow angle can be detected in parallel is that the range detected by the narrow-angle pyroelectric sensor 3 is included in the range detected by the wide-angle pyroelectric sensor 2. This is because, by using the electric sensors 2 and 3 in parallel, it is considered that wildlife can be detected more reliably according to the type of wildlife by limiting the detection range to the optimum range.

  It should be noted that since the detection distance becomes long in the mode only for detecting the narrow angle range, it may be detected unnecessarily far, so a mode for detecting only the wide angle range may be provided.

  The reaction monitor LED 4 is turned on when wildlife or the like is detected, and is provided for confirming the detection operation of the pyroelectric sensors 2 and 3 and confirming the detection range when the sensor unit 10 is installed. It has been.

  On the rear surface of the housing 1, an output monitor LED 5, a camera interface connector 6, a power connector 7, an operation display unit connector 8, an operation switch 9, and a power switch 11 are provided. The output monitor LED 5 is lit to monitor a shutter signal that is output when the pyroelectric sensors 2 and 3 sense wildlife and meet the photographing permission conditions. The camera interface connector 6 outputs a shutter signal for operating the shutter of the camera when the camera is installed in the vicinity of the sensor unit 10 and when the wildlife photography permission condition is satisfied. The power connector 7 is provided so that power can be supplied from an external battery, a solar battery, or the like.

  It should be noted that the present invention can be applied only by detecting and recording wildlife without taking a picture with a camera. In addition, it is possible to reduce the burden on wildlife by limiting the number of times that shooting with a camera is limited to the minimum necessary number. For example, the shutter signal may be output once every time wildlife is detected a plurality of times.

  The operation display unit connector 8 is for electrically connecting and disconnecting the sensor unit 10 and an operation display unit 30 shown in FIG. Note that the connection between the sensor unit 10 and the operation display unit 30 may be wireless communication using light or radio waves instead of using a cable. The operation switch 9 switches between the wide-angle and narrow-angle detection modes and the narrow-angle detection mode based on the detection outputs of the pyroelectric sensors 2 and 3 described above. The power switch 11 is for turning on / off the power supply from the built-in battery.

  An optical finder 12 is detachably provided on the upper surface of the housing 1 via an attachment 13. The optical finder 12 is provided for aiming the direction in which the pyroelectric sensors 2 and 3 face when the sensor unit 10 is installed. That is, the sensor unit 10 is installed in the vicinity of the beast path, etc., and the optical finder 12 is removed after the orientation of the sensor unit 10 is adjusted so that the pyroelectric sensors 2 and 3 are directed in a predetermined direction by looking through the optical finder 12. . This is to reduce the cost when a large number of sensor units 10 are installed in the vicinity of the beast path. For this reason, the optical finder 12 is used in common for the plurality of sensor units 10.

  The optical viewfinder 12 is not necessarily required, and may be provided as necessary. In order to install the sensor unit 10 in the vicinity of the beast path or the like, a metal fitting or the like for attaching to a tripod or a support may be attached to the lower surface of the housing 1.

  FIG. 2 is an external perspective view of the operation display unit 30. The operation display unit 30 shown in FIG. 2 is connected to the sensor unit 10 shown in FIG. 1 to input necessary information or display recorded information. The sensor unit is shown by a cable with a plug (not shown). 10 is connected. The operation display unit 30 includes a housing 31, and a keyboard 32 as an operation unit and a display device 33 as a display unit are provided on the upper surface of the housing 31. The keyboard 32 includes 0 to 9 numeric keys, BS key, ↑ key, ↓ key, ENT key, ESC key, and * key. The keyboard 32 performs setting, recording, and reading mode settings described later, time setting, stop time setting, device recognition number setting, and the like. As the display device 33, a liquid crystal display device for displaying a multi-digit numerical value or a character is used.

  A sensor unit connector 34 and a personal computer connector 35 are provided on the front surface of the housing 31. The sensor unit connector 34 is connected to the operation display unit connector 8 of the sensor unit 10 shown in FIG. 1 by a cable (not shown). The personal computer connector 35 connects the operation display unit 30 to a personal computer (not shown).

  FIG. 3 is a view showing an example in which the sensor unit 10 shown in FIG. 1 is arranged in the vicinity of the animal path. In FIG. 3, sensor units 10 and 10 are arranged at two locations in the vicinity of the animal path 40. First, the sensor unit 10 is installed with a column or the like standing at an appropriate location in the vicinity of the animal path 40. At this time, the direction of the pyroelectric sensors 2 and 3 is set by looking through the optical viewfinder 12 shown in FIG. The optical viewfinder 12 is removed from the sensor unit 10, and the sensor unit 10 is installed in the same manner at the next installation location. Thus, by arranging the sensor units 10 and 10 in the vicinity of the beast tract 40, it is possible to collect information on the behavior of wildlife without threatening the wildlife or giving an excessive load. The number of sensor units 10 is not limited to two, and an arbitrary number may be installed.

  If necessary, the camera 50 may be installed near the sensor unit 10, one end of the release cable may be connected to the camera interface connector 6, and the other end may be connected to the release socket of the camera 50.

  4 is a block diagram of the sensor unit 10 shown in FIG. 1 and the operation display unit 30 shown in FIG. 4, the sensor unit 10 includes pyroelectric sensors 2 and 3, reaction monitor LED 4, output monitor LED 5, camera interface connector 6, power connector 7, and operation display unit connector 8 shown in FIG. In addition to the operation switch 9 and the power switch 11, a level conversion / logic circuit 14, a CPU 15, a weather sensor 16, a gate circuit 17 as a gate means, a camera interface 18, and a real-time clock as a timer means A circuit 19, a backup battery 20, an EEPROM 21 as a recording unit, and a power supply unit 23 are included.

  The pyroelectric sensors 2 and 3 output to the level conversion / logic circuit 14 a signal whose level changes in accordance with the fluctuation of infrared rays accompanying the movement of the wildlife when the wildlife approaches. An operation switch 9 is connected to the level conversion / logic circuit 14, and the operation switch 9 switches between the above-described wide-angle and narrow-angle detection modes and the detection mode for only the narrow angle.

  If the level conversion / logic circuit 14 is switched to the wide-angle and narrow-angle detection modes, the output level of the pyroelectric sensors 2 and 3 is converted to the logic circuit level and output, and the detection mode is limited to the narrow-angle only. If switched, a signal obtained by converting the output level of only the pyroelectric sensor 3 to the level of the logic circuit is output. The output signal of the level conversion / logic circuit 14 is given to one input of the reaction monitor LED 4, the CPU 15, and the gate circuit 17. The reaction monitor LED 4 displays that both the pyroelectric sensors 2 and 3 or only the pyroelectric sensor 3 has reacted to the fluctuation of the infrared rays.

  The level conversion / logic circuit 14 is configured not to accept the signals from the pyroelectric sensors 2 and 3 for a certain time after one of the pyroelectric sensors 2 and 3 reacts and outputs a signal. This is because when a wildlife enters or exits the detection range of the pyroelectric sensors 2 and 3, a signal is output multiple times from the pyroelectric sensors 2 and 3, so one wildlife is counted as a plurality, This is to prevent continuous fire.

  The CPU 15 gives an output permission signal to the other input terminal of the gate circuit 17 when a preset time zone for allowing photographing, for example, a constant night time zone is reached. When the output signal from both the pyroelectric sensors 2 and 3 or only from the pyroelectric sensor 3 is output via the level conversion / logic circuit 14 when the output permission signal is output, the gate circuit 17 outputs an output monitor. The LED 5 is turned on and an output signal is given to the camera interface 18.

  The camera interface 18 outputs a shutter signal, which is a no-voltage on / off signal, to the camera interface connector 6 based on the output signal of the gate circuit 17. By connecting the camera interface connector 6 and the camera 50 shown in FIG. 3 with a release cable (not shown), automatic shooting can be performed.

  The weather sensor 16 is, for example, a sensor that detects temperature and humidity, and is provided to record the temperature and humidity when wildlife is detected. The real-time clock circuit 19 measures the current date and time including the date and time, and is backed up by a backup battery 20 so as to keep measuring time even when the power switch 11 is turned off. The EEPROM 21 stores a program for operating the CPU 15, stores various information input from the operation display unit 30, and stores detection information of the detected wild animals. The weather sensor 16 is not necessarily provided, and may be provided as necessary.

  The power supply unit 23 has a built-in battery, and can supply external power from the power connector 7. A power switch 11 is connected to the power supply unit 23. When the power switch 11 is turned on, a power supply voltage is supplied to each circuit such as the CPU 15. Note that the battery can be charged, and a solar battery or the like may be connected to the power connector 7 as an external power source. In this case, the supply of voltage to each unit can be turned on and off by the power switch 11.

  The operation display unit 30 includes a keyboard 32, a display 33, a sensor unit connector 34, a personal computer connector 35, a serial interface 36, and a GPS (position information detecting means) shown in FIG. A Global Positioning System) receiver 37 is incorporated. The GPS receiver 37 discriminates the position information of the place where the sensor unit 10 is installed by the satellite navigation system and gives it to the CPU 15. Note that the GPS receiver 37 is not necessarily provided, and may be provided in the sensor unit 10 as necessary. The operation display unit connector 8 of the sensor unit 10 and the sensor unit connector 34 of the operation display unit 30 are connected by a cable 38 with a plug.

  Display data is given from the CPU 15 to the display 33 of the operation display unit 30, and time zone information for permitting photographing is given to the CPU 15 from the keyboard 32. A personal computer 60 is connected to the personal computer connector 35 of the operation display unit 30. The serial interface 36 exchanges signals between the CPU 15 and the personal computer 60. The personal computer 60 analyzes the wildlife behavior and the like based on the wildlife detection information stored in the EEOROM 21.

  FIG. 5 is a flowchart for explaining the operation of the wildlife detection sensor device according to the embodiment of the present invention.

  The observer of the wildlife detection sensor device installs the sensor unit 10 at an appropriate location near the animal path 40 as shown in FIG. 3, looks into the optical finder 12 and aims at the pyroelectric sensors 2 and 3. 10 orientations are determined. Then, the display operation unit connector 8 of the sensor unit 10 shown in FIG. 1 and the sensor unit connector 34 of the operation display unit 30 shown in FIG. When the power switch 11 is turned on, the power supply unit 23 supplies a predetermined power supply voltage to the CPU 15 and the like. In response to the power being turned on, the CPU 15 proceeds to the start mode in step (abbreviated as SP in the drawing) SP1.

  In the start-up mode, the CPU 15 waits for, for example, 15 seconds as the time until each circuit stabilizes, and then reads the initial information necessary for the CPU 15 to operate from the EEROM 21 and obtains the current position information where the sensor unit 10 is installed. It is read from the GPS receiver 37 and stored in the EEPROM 21. In step SP2, in response to reading the initial information from the EEPROM 21, the CPU 15 outputs information indicating that the initial setting has been completed to the display device 33 of the operation display unit 30 for display.

  Viewing the display, the observer depresses the ESC key on the keyboard 32 for 4 seconds or more, for example. 4 seconds is an arbitrary time, and may be shorter or longer. In step SP3, it is determined whether or not the ESC key has been pressed, and it is determined in step SP4 that the ESC key has not been pressed after a predetermined time of 4 seconds or more, for example, 10 seconds. The process proceeds to step SP3.

  If the CPU 15 determines in step SP3 that the ESC key has been pressed, the CPU 15 allows setting of the setting mode, the recording mode, and the reading mode. For this purpose, in step SP5, “mode can be set” is displayed on the display 33. To set each mode, for example, press the ↑ key to enter the setting mode, press the ↓ key to enter the reading mode, and enter the recording mode if neither the ↑ key nor the ↓ key is pressed within the specified time. It is predetermined to become.

  The mode setting by this key operation is arbitrary. For example, each time the ↑ key is pressed, the setting, recording, and reading modes may be set.

  The mode name is displayed on the display 33 each time each mode is set. In this embodiment, when the observer presses the ↑ key and then presses the ENT key, the setting mode is determined. When the CPU 15 determines in step SP6 that the ↑ key has been pressed, the CPU 15 displays the setting mode on the display 33 as “setting mode” in step SP7.

  When the ENT key is depressed to select the setting mode, in step SP8, the CPU 15 determines that the ENT key has been depressed, and determines the setting mode. If the ENT key is not depressed, the process waits. In the setting mode, the observer inputs the start time and end time of the time zone during which photographing is permitted from the numeric keypad, inputs information such as the device number of the sensor unit 10 and the characteristics of the installation location, and then presses the ENT key. Manipulate. In step SP9, the CPU 15 determines whether or not various types of information have been input. If it is determined that the information has been input, in step SP10, the start time and end time of the time zone in which the input photographing is permitted, the device number, etc. Various information is stored in the EEPROM 21.

  In step SP11, it is determined whether or not the ESC key has been pressed for 4 seconds. If it is determined in step SP12 that the ESC key has not been pressed until a predetermined time, the process returns to step SP9 to set in the setting mode. Wait for input. If the ESC key is not depressed by the predetermined time, the display 33 is displayed in step SP13 to indicate that the recording mode is set.

  Since the operation display unit 30 is unnecessary in the recording mode, the observer removes it from the sensor unit 10. However, the recording mode may be executed with the operation display unit 30 mounted on the sensor unit 10. If the camera 50 is installed in the vicinity of the sensor unit 10 as shown in FIG. 3 and the camera 50 and the camera interface connector 6 are connected by a release cable, the pyroelectric sensors 2 and 3 are wild. Each time a living organism is detected and a shutter signal is output, automatic shooting by the camera 50 becomes possible. When the observer is set to the recording mode, the observer leaves the installation location of the sensor unit 10.

  When the recording mode is set, the CPU 15 reads the current date and time counted by the real-time clock circuit 19, and determines whether or not it is a time zone for allowing photographing stored in the EEPROM 21 in step SP14. To do. If it is within the time zone, an output permission signal is output at step SP15, and if it is not within the time zone, the output permission signal is stopped at step SP16.

  At this time, the pyroelectric sensors 2 and 3 move the wildlife within the detection range, and change the output signal if there is a change in the infrared light accompanying the movement. If the mode is switched to the mode for detecting only the pyroelectric sensor 3, the output signal from the pyroelectric sensor 3 is taken into the level conversion / logic circuit 14 and switched to the mode for detecting the wide angle and the narrow angle in parallel. Then, the outputs of the pyroelectric sensors 2 and 3 are taken into the level conversion / logic circuit 14.

  That is, the level conversion / logic circuit 14 determines whether the wide-angle and narrow-angle detection mode or the narrow-angle mode is set by the operation switch 9, and the detection output of the pyroelectric sensors 2 and 3 in each mode. A signal whose level is converted in accordance with is output. This signal is given to the CPU 15 and one input of the gate circuit 17 and to the reaction monitor LED 4 so that the reaction monitor LED 4 is lit.

  In step SP15, when one gate of the gate circuit 17 is opened by the output permission signal, the level-converted sensor output signal is output, the output monitor LED 5 is turned on, and the shutter signal is sent from the camera interface 18 to the camera interface. Output to connector 6. Thereby, automatic photographing by the camera 50 is performed. Since the CPU 15 is in a time zone during which photographing is permitted, the sensor output is captured in step SP17.

  In step SP18, the CPU 15 reads the output signal of the level conversion / logic circuit 14 and records it in the EEPROM 21 as detection information in order to record that wildlife has been detected. And the current temperature and humidity are read from the weather sensor 16 and stored in the EEPROM 21 corresponding to the wildlife detection information. In step SP19, it is determined whether or not the ESC key has been pressed for 4 seconds.

  Unless the observer presses the ESC key, the operation in the recording mode is executed, and the wildlife passing through the animal path is detected during that time, and the detection information is stored in the EEPROM 21 together with the detection date and time, the detection temperature and the humidity. It is also possible to take pictures of wildlife detected by the camera.

  When the output permission signal is stopped in step SP16, the process proceeds to step SP19 without recording the detection information. However, as indicated by the dotted line in FIG. 5, the sensor output is captured in step SP17, and the process proceeds to step SP18. The detection information may be recorded.

  When ending the observation, the observer depresses the ESC key for 4 seconds. If the CPU 15 determines in step SP19 that the ESC key has been depressed, the CPU 15 proceeds to step SP5 and displays on the display 33 that the mode can be set. When reading the recorded information, the observer depresses the ↓ key and then depresses the ENT key. If it is not possible to determine in step SP6 that the ↑ key has been depressed, and if it is determined in step SP20 that the ↓ key has been depressed, “reading mode” is displayed on the display 33 in step SP21. . When it is determined that the ↓ key has not been depressed within a certain time, the process returns to step SP6.

  In step SP22, it is determined whether or not the ENT key has been depressed. If it has been depressed, the stored detection information is read from the EEPROM 21 and displayed on the display 33 in step SP23, and the detection information is also displayed. Are output to the personal computer 60 via the serial interface 36. Thus, necessary editing can be performed on the screen of the personal computer 60, and data can be printed by a printer or the like.

  In step SP24, it is determined whether or not the ESC key has been pressed. If it is determined in step SP25 that the predetermined time has not elapsed and the key has not been pressed, the process returns to step SP13 and shifts to the recording mode. When ending the observation, for example, the BS key is operated to end the process, and the power switch 11 is turned off.

  As described above, according to the embodiment of the present invention, the wide-angle pyroelectric sensor 2 and the narrow-angle pyroelectric sensor 3 built in the sensor unit 10 are used. Because the detection information of wildlife can be continuously recorded in the EEPROM 21 together with the date and time based on the change in the infrared rays accompanying the movement of the wildlife detected in 3, for example, at night, the animal can move in the beast road without an observer. It will be possible to record the ecology of wildlife such as mammals and birds flying around in the forest.

  In addition, corresponding to wildlife detection information, weather information such as time and temperature and humidity can be recorded at the same time, which can be useful for observing the wildlife ecology.

  Furthermore, it is possible to identify wildlife by installing the camera 50 in the vicinity of the sensor unit 10 and limiting the number of shootings to a minimum so as not to give a load to the wildlife.

  (5) The sensor unit includes gate means for prohibiting the output of the detection signal within a certain period in response to the detection of the movement of the wildlife by the sensor element.

  As mentioned above, although embodiment of this invention was described with reference to drawings, this invention is not limited to the thing of embodiment shown in figure. Various modifications and variations can be made to the illustrated embodiment within the same range or equivalent range as the present invention.

  The wildlife detection sensor device of the present invention can be used for recording and investigating the ecology of wildlife moving in the beast path and birds flying in forests.
