Description

  The present invention relates to a wild animal capturing system, and more particularly, to a wild animal capturing system for capturing a collective wild animal that performs herd behavior.

  Conventionally, crop damage caused by collective wild animals, such as deer and wild boar, that have swarmed has become serious, and various countermeasures have been implemented. Among these various measures, a measure for capturing and exterminating the target wild animals is an effective measure in that it can directly reduce the number of wild animals that cause crop damage.

  For this reason, conventionally, a wild animal capture system for capturing wild animals has been proposed (see, for example, Patent Document 1).

  Patent Document 1 discloses an animal capture device (wild-type) including a cage, a photoelectric sensor that detects that a wild animal has entered the trap area, a door that closes the cage, and a controller that operates the door. Animal capture systems) are disclosed. In this animal capture device, when it is detected by the photoelectric sensor that a wild animal has entered the capture area, the control unit closes the cage by operating the door after a predetermined waiting time has elapsed since the detection by the photoelectric sensor. It is configured as follows. As a result, after the first intrusion is detected by the photoelectric sensor, when a plurality of heads enter the capture region in a predetermined waiting time, it is possible to capture the plurality of heads together.

Japanese Patent Laid-Open No. 2004-321039

  However, in the animal capture device (wild animal capture system) of Patent Document 1 above, a plurality of collective wild animals that take a group action in a predetermined waiting time after the first intrusion is detected by the photoelectric sensor. In case of intrusion into the capture area, it is possible to capture multiple animals at once, while the invasion of the first animal was detected by the photoelectric sensor even in the case of a collective wild animal that was swarming After that, when there is no invasion of other individuals within a predetermined waiting time, or when an individual that has once entered the capturing area is withdrawn from the capturing area at a predetermined waiting time, a sufficient number of heads can be captured in a single capturing operation. Since wild animals may not be captured together, there is a problem that it is difficult to reliably improve the capture efficiency.

  The present invention has been made to solve the above-described problems, and one object of the present invention is to provide a wild wild animal that can reliably improve the capture efficiency of a collective wild animal that takes a herd behavior. It is to provide an animal capture system.

Means for Solving the Problems and Effects of the Invention

  A wild animal capturing system according to one aspect of the present invention is a wild animal capturing system for capturing a collective wild animal that takes a group action, a capturing unit that captures a wild animal in a capturing area, and a capturing area In the case where the number of wild animals in the capture area measured by the measurement section and the number of wild animals in the capture area is greater than or equal to the first expected number of wild animals that can be captured in the capture area, Control that activates the capture unit to capture wild animals in the capture area and sets the waiting time until the capture unit is activated based on the number of wild animals in the capture area measured by the measurement unit A part. In addition, the collective wild animal which takes a herd behavior is a deer, a wild boar, a raccoon, a nutria, a monkey, etc., for example.

  In the wild animal capturing system according to one aspect of the present invention, as described above, the control unit causes the first number of wild animals that can be captured in the capturing region to be captured by the capturing unit. By configuring the capture unit to operate to capture wild animals in the capture area when the number is greater than the expected number of captures, the control unit captures wild animals greater than the first number of potential captures. Since the capture unit is controlled, it is possible to prevent the capture operation from being executed even though there are not enough heads in the capture region. Thereby, the capture efficiency of the collective wild animal which takes herd behavior can be improved reliably. In addition, by configuring the control unit to set a waiting time until the capture unit is activated based on the number of wild animals in the capture region measured by the measurement unit, the wild animals are continuously captured. When invading into the area, since the capture operation is executed after waiting for more wild animals to invade using the waiting time, the number of captured animals can be further increased. Thereby, the capture efficiency of the collective wild animal which takes herd behavior can be improved more.

  In the wild animal capturing system according to the above aspect, preferably, the control unit is equal to or greater than a second expected number of captured animals whose number of wild animals in the capture region measured by the measuring unit is greater than the first estimated number of captured animals. In this case, the waiting time until the capture unit is operated is set to the first waiting time or no waiting time, and the number of wild animals in the capture area measured by the measurement unit is the second expected number of catches. If the number is less than the first expected number of catches, the waiting time until the capturing unit is activated is set to a second waiting time longer than the first waiting time. With this configuration, when the number of wild animals in the capture area is small, the standby time is set longer than when the number of wild animals in the capture area is large. Can be used to allow more wild animals to enter the capture area. On the other hand, if the waiting time becomes too long, there is a possibility that an individual that has entered the capture area will be evacuated from the capture area during the waiting time, so if there are many wild animals in the capture area, It is possible to suppress an increase in the number of individuals evacuated from the capture area with a short standby time or without a standby time. Thereby, since the capture operation can be executed with an appropriate waiting time according to the number of wild animals in the capture area, the capture efficiency of the wild animals can be further improved.

  In this case, preferably, the first expected number of capture animals is the lowest number of expected wild animals that can be captured in the capture area, and the second expected number of capture animals is the maximum number of wild animals that can be captured in the capture area. Expected number of animals. If comprised in this way, since more suitable standby | waiting time can be set according to each of the minimum expected number of capture and the maximum number of expected capture, the capture efficiency of a wild animal can further be improved.

  In the wild animal capturing system according to the above aspect, preferably, the control unit determines a first expected number of wild animals that can be captured in the capture region based on the measurement result by the measurement unit, and the measurement unit measures When the number of wild animals in the captured area is equal to or greater than the first expected number of captured animals, the capture unit is operated to capture the wild animals in the capture area and is measured by the measurement unit. Based on the number of wild animals in the capture area, a waiting time until the capture unit is activated is set. If comprised in this way, based on the measurement result by a measurement part by a control part, while the 1st capture possibility number of heads is determined automatically, and based on the 1st number of expected capture number of animals automatically determined Since the capture unit is activated, it is not necessary for the user to determine the first expected number of captures. Thereby, it can suppress more that a user is burdened, improving the capture efficiency of a wild animal.

  In the wild animal capturing system according to the one aspect described above, preferably, the wild animal capturing system preferably further includes a retreat detecting unit that detects that the wild animal has retreated from the capture region, and the control unit retreats the wild animal from the capture region by the retreat detecting unit. If it is detected that the number of wild animals in the capture area measured by the measurement unit is equal to or greater than the first expected capture number, regardless of the waiting time until the capture unit is activated. , Configured to control to capture wild animals in the capture area. According to this configuration, when the evacuation detection unit detects the evacuation from the capture area, the capture operation is performed without waiting for the elapse of the standby time. Even in the case of (escape), it is possible to suppress an increase in the number of evacuated (escape) heads.

  In the wild animal capture system according to the above aspect, preferably, the capture unit includes a gate unit through which the wild animal can enter and exit the capture region, and a closing unit that closes the gate unit when the capture unit is operated by the control unit. And a presence / absence detection unit that detects whether or not there is a wild animal in the vicinity of the closing part, and the control unit detects that the presence / absence detection unit detects that the wild animal is in the vicinity of the closing part. Is configured to control so that the closing portion does not close the gate portion. If comprised in this way, when closing a gate part by a closed part, it can suppress that the accident which a wild animal will be pinched by the closed part occurs. In addition, if wild animals are caught in the closed part, there is a risk that other individuals may escape from the gaps of the closed part caused by the individual caught, so that wild animals are not caught in the closed part Therefore, such escape can also be suppressed.

  In the wild animal capturing system according to the above aspect, preferably, the control unit sets the waiting time until the capturing unit is activated, and then waits for the set waiting time to elapse. When the number of animals increases, the waiting time until the capture unit is activated is newly set. If configured in this way, even if the waiting time is once set, if there is a new intrusion into the capture area within the waiting time, the waiting time can be extended. When wild animals invade continuously into the capture region, the invading wild animals can be captured more efficiently.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments embodying the present invention will be described below with reference to the drawings.

  First, with reference to FIG. 1, the structure of the wild animal capture system 100 by one Embodiment of this invention is demonstrated.

  The wild animal capturing system 100 according to an embodiment of the present invention is a system for capturing a collective wild animal that takes a herd behavior. In addition, as will be described later, the wild animal capturing system 100 is configured to determine the expected number of animals to be captured in the confirmation mode, and to capture the wild animals to be captured in the capture mode based on the determined estimated number of animals to be captured. Yes. Below, the detail of the wild animal capture system 100 of this embodiment is demonstrated. In addition, the collective wild animal which takes a herd behavior is a deer, a wild boar, a raccoon, a nutria, a monkey, etc., for example. In the present embodiment, a wild animal capturing system 100 for capturing a deer among these collective wild animals will be described. In addition, deer is addictive with respect to daily activities including foraging behavior, and tends to appear to eat at approximately the same time every day.

  As shown in FIG. 1, the wild animal capturing system 100 includes an enclosure trap 1 and a control device 2. The enclosure trap 1 is provided with a release unit 3, a count sensor 4 and a photoelectric sensor 5 which will be described later. Further, in the present embodiment, the control device 2 and the count sensor 4 constitute a prospective number determination device for determining the number of prospective catches. The enclosure trap 1 is an example of the “capture unit” of the present invention, and the count sensor 4 is an example of the “measurement unit” and the “retraction detection unit” of the present invention. The photoelectric sensor 5 is an example of the “presence / absence detection unit” in the present invention.

  As shown in FIG. 1, the enclosure trap 1 is formed by assembling a metal pipe 11 such as aluminum. More specifically, the frame 1 has a skeleton formed by a plurality of metal pipes 11, and a mesh-shaped metal panel 12 is disposed between the metal pipes 11 so as to surround the four sides. By using the metal pipe 11 and the mesh-like metal panel 12 in this way, the configuration of the enclosure trap 1 can be simplified, so that the enclosure trap 1 can be easily installed and disassembled. . When capturing wild animals, the target wild animals may not be able to reach the place where the traps are installed. In such cases, it will be necessary to change the trap location, and the traps will be installed and dismantled. Is required. Further, inside the enclosure trap 1 (within the capture area), food for attracting deer inside the enclosure trap 1 is placed.

  The enclosure trap 1 is provided with one gate portion 13 for allowing deer to enter the inside of the enclosure trap 1 (within the capture region) and a door portion 14 capable of closing the gate portion 13. Yes. The door portion 14 is configured to be slidable up and down along the frame of the gate portion 13. Moreover, the door part 14 is comprised so that the gate part 13 may be open | released in the state lifted up, and the gate part 13 may be obstruct | occluded in the state dropped down. Specifically, the door portion 14 is lifted upward by a tensile force caused by a wire (not shown) when the deer is enclosed in the trap 1. Moreover, the release part 3 which cancels | releases the tension | tensile_strength which lifts the door part 14 is provided in the enclosure trap 1, and the door part 14 falls below by the dead weight of the door part 14 when the release part 3 act | operates. It is configured as follows. That is, when the release portion 3 is operated, the gate portion 13 is closed by the door portion 14. The door portion 14 is an example of the “closing portion” in the present invention.

  The control device 2 includes a power supply unit 21 that supplies power to each unit, a communication unit 22, a storage unit 23, and a control unit 24 that controls the operation of each unit. Further, the control device 2 is configured such that power is supplied from the battery 6 via the power supply unit 21. The control device 2 is connected to the release unit 3, the count sensor 4, and the photoelectric sensor 5 via the communication unit 22 so as to be communicable. Specifically, the control device 2 is configured to be able to transmit a signal for operating the release unit 3 to the release unit 3 via the communication unit 22. The control device 2 is configured to be able to acquire a measurement result from the count sensor 4 via the communication unit 22. The control device 2 is configured to be able to acquire a detection result from the photoelectric sensor 5 via the communication unit 22. The control device 2 is configured to be able to control power supply from the battery 6 to the release unit 3, the count sensor 4, and the photoelectric sensor 5. That is, the control device 2 is configured to be able to switch between a state where power is supplied from the battery 6 and a state where no power is supplied to the release unit 3, the count sensor 4 and the photoelectric sensor 5. With this configuration, power supply to the release unit 3, the count sensor 4, and the photoelectric sensor 5 is stopped in a time zone other than the time zone in which the confirmation mode process and the capture mode process described later are executed.

  The storage unit 23 is composed of a rewritable nonvolatile flash memory. The storage unit 23 stores a count list 231 in which measurement results are accumulated.

  In the confirmation mode, the control unit 24 is configured to determine the number of deer that can be captured in the enclosure trap 1 (capture region) based on the measurement result of the count sensor 4. In addition, the control unit 24 is configured to perform control to execute the capture operation in the capture mode based on the expected number of captures determined in the confirmation mode and the number of deer in the enclosure 1 (in the capture region). Has been. Specifically, the control unit 24 performs control to transmit a signal for operating the release unit 3 based on the expected number of captures and the number of deer in the enclosure 1 (in the capture region). The control unit 24 has a clock function. The processing of the control unit 24 in the confirmation mode and the capture mode will be described in detail in the description of the confirmation / capture processing described later.

  The count sensor 4 is composed of an optical sensor and has a function of counting (measuring) the number of intrusions into the deer enclosure 1 (capture area) and the number of retreats from the enclosure 1 (capture area). ing. Further, the count sensor 4 is configured to be able to measure the number of deer in the enclosure trap 1 (within the capture area) in a non-contact manner from the difference between the number of deer intrusions and the number of retreats.

  The photoelectric sensor 5 is provided to detect whether or not there is a deer below the door portion 14 in a non-contact manner. As will be described later, the control unit 24 determines whether or not to drop the door unit 14 based on the detection result of the photoelectric sensor 5. Thereby, it becomes possible to suppress the occurrence of an accident in which a deer is pinched by the door portion 14. Further, the photoelectric sensor 5 can detect not only deer but also people and objects, and it is possible to prevent people and objects from being accidentally sandwiched between the door portions 14 based on the detection result of the photoelectric sensor 5. Is possible. Moreover, when a deer, a person, an object, etc. are pinched | interposed into the door part 14, there exists a possibility that the deer in a capture area may escape from the clearance gap between the door part 14 and the ground.

  Next, the confirmation / capture process executed by the control unit 24 will be described with reference to FIG.

  First, in step S1, the control unit 24 receives an input of an initial setting value set by a user (capturer). The user needs to set the time zone (start time and end time) for executing the confirmation mode process and the capture mode process, the desired minimum number of captured animals, the maximum number of confirmation days, and the minimum number of confirmation days. At this time, it is preferable to set a time zone in which the deer acts actively as a time zone for executing the process in the confirmation mode and the process in the capture mode in view of the habit of the daily activity. As a result, since the confirmation mode process and the capture mode process are not executed in a time zone other than the time zone during which the deer actively acts, it is possible to reduce the power consumption of each unit during that time. In addition, in the time zone other than the time zone during which the deer is actively acting, the possibility that the deer will enter the enclosure 1 (in the capture area) is low, so the processing in the capture mode is not executed in such a time zone. Even so, it is considered that the capture efficiency does not decrease. In addition, the user needs to set the minimum number of animals that he / she wants to capture as the desired minimum number of animals to be captured from the capture location where the enclosure trap 1 is installed and the capture time (season, etc.). In addition, the user needs to set the maximum number of days for executing the confirmation mode as the maximum number of confirmation days and the minimum number of days for executing the confirmation mode as the minimum number of confirmation days. That is, the user needs to set the maximum number of days and the minimum number of days for measuring the number of deer in the enclosure 1 (capture area) in the confirmation mode as the maximum number of confirmation days and the minimum number of confirmation days, respectively.

  When the acceptance of the initial setting is completed, in step S2, the control unit 24 determines whether or not the current time has passed the start time set in the initial setting, and repeats this determination until the start time is reached. When the current time has passed the start time, the control unit 24 determines in step S3 whether or not it has already shifted to the capture mode. The transition from the confirmation mode to the capture mode is performed after the expected number of captures is determined in the confirmation mode. Thereafter, the control unit 24 executes the process of the confirmation mode in step S4 when the mode is not shifted to the capture mode, and executes the process of the capture mode of step S5 when the mode is already shifted to the capture mode. That is, when the expected number of captures is not determined, the capture mode process is not executed.

  Next, the confirmation mode process in step S4 of FIG. 2 will be described with reference to FIG.

  In step S <b> 41, the control unit 24 acquires from the count sensor 4 the measurement result of the number of deer (number of individuals) in the enclosure 1 (in the capture area). In step S42, the control unit 24 determines whether or not the current time has passed the end time set in the initial setting, and continues to acquire the measurement result by the count sensor 4 until the end time is reached. When the end time has passed, the control unit 24 records the maximum number of heads (maximum number of individuals) of the day in the count list 231 of the storage unit 23 in step S43. In the count list 231, the maximum number of heads measured each day in the confirmation mode process is accumulated.

  Thereafter, in step S44, the control unit 24 determines whether the maximum number of confirmation days set in the initial setting has passed. When the maximum number of confirmation days has not passed, the control unit 24 sets the number of days for which the maximum number of animals accumulated in the count list 231 is equal to or greater than the minimum number of captured animals to be equal to or greater than the minimum confirmation number of days set in the initial setting. If the number of days that is equal to or greater than the minimum number of captured animals is not equal to or greater than the minimum number of confirmation days, the confirmation mode processing for that day is terminated as it is.

  Here, the determination in step S45 will be described with a specific example with reference to FIG. For example, if the maximum confirmation days is set to 10 (days), the minimum confirmation days is set to 3 (days), and the minimum number of captured animals is set to 5 (heads), the minimum confirmation days is 3 (days). In any case of 1 to 3, in the judgment up to the second day, it is determined that the number of days over the minimum number of captured animals is not over the minimum number of confirmed days (the number of days over the minimum number of captured animals is less than the minimum number of confirmed days). And in case 1, since the maximum number of animals is equal to or greater than the minimum number of animals (5 (heads)) on all the days from the first day to the third day, the control unit 24 determines in step S45 on the third day. The number of days over the minimum number of captured animals (5 (heads)) is determined to be greater than the minimum number of confirmed days (3 (days)). Further, in case 2, in the determination of step S45 on the sixth day, the control unit 24 determines that the number of days that is equal to or greater than the minimum number of captured animals (5 (heads)) is equal to or greater than the minimum number of confirmed days (3 (days)). The On the other hand, in the case of case 3, the number of days over the minimum number of captured animals (5 (heads)) is not judged to be more than the minimum number of confirmed days (3 (days)) until the 9th day, and 10 days. In step S44, it is determined that the maximum number of confirmation days (10 (days)) has passed, and the process proceeds to step S46.

  When the maximum number of confirmation days has passed and when the number of days more than the minimum number of captured animals has reached the minimum number of confirmation days, the process proceeds from step S44 and step S45 to step S46, respectively. In step S46, the control unit 24 determines the maximum number of expected captures and the minimum number of expected captures based on the measurement results accumulated in the count list 231. At this time, the control unit 24 determines the highest number of heads out of the maximum number of heads stored in the count list 231 as the maximum number of heads expected to be captured. For example, in case 1 of FIG. 4, 10 (heads) on the second day, which is the maximum of the accumulated three days, is determined as the maximum number of expected catches. Similarly, in cases 2 and 3, 8 (heads) and 7 (heads), which are the maximum of the accumulated days, are determined as the maximum number of expected catches, respectively.

  Moreover, the control part 24 determines the average value for the lowest minimum confirmation days of the highest number of each day accumulate | stored in the count list | wrist 231 as a minimum capture | expected number. For example, in the case of the case 1, the highest ranks for the minimum number of confirmation days (3 (days)) among the maximum number of heads accumulated for each day are 10, 7 and 5 in order from the top. For this reason, in the case of case 1, 7 heads, which is an average value of 10 heads, 7 heads, and 5 heads, are determined as the minimum number of expected heads. In the present embodiment, the average value is calculated by rounding off the first decimal place. In case 2, the highest number of days for the minimum number of confirmation days (3 (days)) is 8, 5 and 5 in order from the top, and the average of these 6 is the lowest capture. Determined as the expected number of animals. In the case of case 3, the top of the minimum number of confirmation days (3 (days)) is 7, 4 and 3 in order from the top, and the average of these 5 is the minimum capture. Determined as the expected number of animals.

  In the present embodiment, as in the above cases 1 and 2, even when the maximum number of confirmation days (10 (days)) has not passed, the number of days over the minimum number of captured animals (5 (heads)) is the minimum number of confirmation days (3 (days )) If this is the case, the control unit 24 determines the maximum number of expected captures and the minimum number of potential captures. Then, after the expected number of catches is determined, the control unit 24 switches the mode from the confirmation mode to the capture mode in step S47, and ends the process of the confirmation mode.

  Next, the capture mode process in step S5 of FIG. 2 will be described with reference to FIG.

  In step S <b> 51, the control unit 24 acquires a measurement result of the number of deer (number of individuals) in the enclosure 1 (capture area) from the count sensor 4. In step S52, the control unit 24 determines whether or not the current time has passed the end time set in the initial setting, and ends the capture mode processing when the end time is reached. If the end time has not passed, the control unit 24 checks whether or not a deer has newly entered based on the measurement result of the count sensor 4 in step S53. If there is a new intrusion, the control unit 24 determines in step S54 whether the number of deer in the enclosure 1 is equal to or greater than the maximum number of expected captures determined in the above confirmation mode process. To do. If the number of deer in the enclosure 1 is equal to or greater than the maximum number of expected catches, the control unit 24 sets a waiting time until the release unit 3 is operated so that the door unit 14 is dropped in step S55. Set to seconds. At this time, if there is a previously set standby time (when counting down), the control unit 24 resets the previously set standby time and newly sets the standby time to 5 seconds. Thereafter, the control unit 24 performs the operation of acquiring the measurement result in step S51 again. That is, when the number of deer in the enclosure 1 is equal to or greater than the maximum number of expected catches, the waiting time is reset every time there is a new intrusion.

  On the other hand, when the number of deer in the enclosure trap 1 is not equal to or greater than the maximum number of expected captures (less than the maximum number of captures), the control unit 24 confirms the number of deer in the enclosure trap 1 in step S56. It is determined whether or not the number is less than the maximum number of expected captures and less than the maximum number of expected captures determined in the mode processing. When the number of deer in the enclosure 1 is equal to or greater than the minimum number of expected captures and less than the maximum number of potential captures, the control unit 24 sets the maximum waiting time until the release unit 3 is activated in step S57. It is set to 30 seconds longer than the case where the number is more than the expected number of animals (in the case of Step S55), and the operation returns to Step S51. At this time, similarly to the operation in step S55, the control unit 24 resets the previously set waiting time and newly waits when there is a previously set waiting time (when the countdown is in progress). Reset the time to 30 seconds. As described above, in the present embodiment, the control unit 24 sets the standby time based on the number of deer in the enclosure 1. If the number of deer in the enclosure 1 is not equal to or less than the minimum expected number of captures (less than the minimum expected number of captures), the control unit 24 returns to the operation of step S51 without setting the standby time.

  In addition, when there is no new deer intrusion, the control unit 24, after step S53, in step S58, the minimum number of expected catches in which the number of deer in the enclosure 1 is determined by the processing in the confirmation mode described above. If it is not more than the minimum expected number of catches (if less than the minimum expected number of catches), the operation returns to step S51. If the number of deer in the enclosure trap 1 is greater than or equal to the minimum expected number of captures, the control unit 24 retreats (escapes) from the enclosure trap 1 based on the measurement result of the count sensor 4 in step S59. Determine whether or not. If there is no deer evacuation, the control unit 24 determines in step S60 whether or not the standby time set in step S55 or S57 has elapsed. If the standby time has not elapsed, the control unit 24 returns to the operation of step S51. . On the other hand, when the standby time has elapsed, the control unit 24 determines whether or not there is a deer below the door unit 14 based on the detection result of the photoelectric sensor 5 in step S61. In step S62, capture is executed. Specifically, in step S <b> 62, the control unit 24 operates the release unit 3 to drop the door unit 14 and close the gate unit 13. If there is a deer below the door part 14, the control part 24 returns to the operation of step S51. Thereby, it is possible to suppress the occurrence of an accident that a deer is pinched by the door portion 14.

  If it is confirmed that the deer has been retracted, in step S63, the control unit 24 determines whether or not the number of deer in the enclosure 1 is equal to or greater than the minimum number of expected capture, and exceeds the minimum number of expected capture. If not (if it is less than the minimum expected number of animals), the process returns to step S51. That is, in the wild animal capture system 100 of the present embodiment, in steps S58 and S63, the control unit 24 determines whether or not the number of deer in the enclosure 1 is equal to or greater than the minimum expected number of captures, and the minimum capture When the number is less than the expected number, control is performed so that the capture operation is not performed. In other words, in this embodiment, the capture operation is executed by the control unit 24 only when the number of deer in the enclosure 1 is equal to or greater than the minimum expected capture number.

  Even after deer evacuation, if the number of deer in the enclosure 1 is equal to or greater than the minimum number of expected catches, the process immediately proceeds to step S61 regardless of the set waiting time. That is, when the number of deer in the enclosure 1 is equal to or greater than the minimum number of expected catches, the control unit 24 proceeds to step S61 without waiting for the waiting time to elapse. As a result, even when multiple deer are evacuating from the enclosure trap 1, they can be captured immediately, increasing the number of deer evacuation from the enclosure trap 1. It is possible to suppress.

  In this embodiment, as described above, the control unit 24 causes the deer population in the enclosure trap 1 (in the capture region) measured by the count sensor 4 to be equal to or greater than the minimum number of deer that can be captured in the capture region. In this case, the release portion 3 of the enclosure trap 1 is operated so as to capture the deer in the capture region. As a result, the release unit 3 is controlled by the control unit 24 so as to capture a deer that is more than the minimum number of expected catches, so that the capture operation is executed even though there are not enough numbers in the capture region. Can be suppressed. Thereby, the capture efficiency of the collective deer which takes a herd action can be improved reliably. Further, the control unit 24 is configured to set a waiting time until the release unit 3 of the enclosure trap 1 is activated based on the number of deer individuals in the capture area measured by the count sensor 4. This makes it possible to increase the number of heads to catch since deer intrudes into the capture area in a row because the capture operation is executed after waiting for more deer to enter using the waiting time. . Thereby, the capture efficiency of the collective deer which takes a herd action can be improved more.

  Further, in this embodiment, when the number of deer individuals in the capture area measured by the count sensor 4 is equal to or greater than the maximum expected number of catches, the waiting time is set to 5 seconds, and the number of deer individuals in the capture area Is less than the maximum expected number of catches and more than the minimum expected number of catches, the control unit 24 is configured to set the waiting time to 30 seconds. With this configuration, when the number of deer individuals in the capture area is small, the standby time is set longer than when the number of deer individuals in the capture area is large. Thus, more deer can enter the capture area. On the other hand, if the waiting time becomes too long, deer once entered the capture area may be withdrawn from the capture area during the waiting time, so if there is a large number of deer individuals in the capture area, It is possible to suppress an increase in the number of deer evacuating from the capture region by shortening the time. Thereby, since the capture operation can be executed with an appropriate waiting time corresponding to the number of deer individuals in the capture area, the capture efficiency of deer can be further improved.

  Further, in the present embodiment, based on the measurement result by the count sensor 4, the minimum number of deer that can be captured in the capture region in the confirmation mode is determined, and the number of deer individuals in the capture region is the minimum number of potential capture. In the above case, the control unit 24 is configured to operate the release unit 3 of the enclosure trap 1 so as to capture the deer in the capture region. If comprised in this way, based on the measurement result by the count sensor 4 by the control part 24, while the minimum capture | expected number of heads is determined automatically, an enclosure trap is based on the automatically determined minimum number of heads of capture. Since 1 release part 3 is operated, it is not necessary to determine the minimum number of expected catches by the user.

  Further, in this embodiment, when it is detected that the deer has been withdrawn from the capture area, if the number of deer in the capture area is equal to or greater than the minimum expected capture number, the capture is performed regardless of the waiting time. The control unit 24 is configured to control to capture deer in the area. With this configuration, when the withdrawal from the capture area is detected by the count sensor 4, the capture operation is executed without waiting for the waiting time to elapse. Even in the case of (escape), it is possible to suppress an increase in the number of evacuated (escape) heads.

  In the present embodiment, the control unit 24 is configured to control the door unit 14 not to close the gate unit 13 when the photoelectric sensor 5 detects that the deer is below the door unit 14. To do. If comprised in this way, when closing the gate part 13 with the door part 14, it can suppress that the accident which a deer gets caught in the door part 14 generate | occur | produces. In addition, if a deer is pinched in the door part 14, there is a risk that another deer may escape from the gap of the door part 14 caused by the pinched deer, so that the deer is not pinched in the door part 14. Therefore, such escape can also be suppressed.

  Moreover, in this embodiment, after the standby time until the control unit 24 operates the release unit 3 of the enclosure trap 1 is set and before the set standby time elapses, the deer in the capture area When the number of individuals increases (when there is a new intrusion), the waiting time is newly set again. If configured in this way, even if the waiting time is once set, if there is a new intrusion into the capture area within the waiting time, the waiting time can be extended. When deer continuously enters the capture area, the deer that enters can be captured more efficiently.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is shown not by the above description of the embodiments but by the scope of claims for patent, and further includes all modifications within the meaning and scope equivalent to the scope of claims for patent.

  For example, in the said embodiment, although the enclosure trap was shown as an example of the capture part of this invention, this invention is not limited to this. In the present invention, for example, it may be a catching part other than a trapping trap such as a trapping net, a trap trap, a box trap, a throwing trap, and the like.

  Moreover, in the said embodiment, although the example of the structure which provides one gate part in the enclosure trap as a capture part was shown, this invention is not limited to this. In this invention, the structure which provides a some gate part in a capture part may be sufficient. In this case, a configuration in which a measurement unit is provided in each gate unit and the number of wild animals in the capture region is measured based on the measurement results of the plurality of measurement units is preferable. Further, when performing the capturing operation, it is preferable to close the plurality of gate portions substantially simultaneously.

  Moreover, although the said embodiment demonstrated the wild animal capture system for capturing especially a deer among the collective wild animals which take a herd action, this invention is not limited to this. In the present invention, wild animals other than deer, such as wild boars, raccoons, nutria, monkeys, and the like, may be used as long as they are collective wild animals that take herd behavior. In this case, it is preferable to use a capture unit having a form suitable for the animal to be captured and a size suitable for the animal to be captured.

  Moreover, although the count sensor which consists of an optical sensor was shown as an example of a measurement part in the said embodiment, this invention is not limited to this. In the present invention, for example, a measurement unit other than the count sensor may be used, such as a measurement unit that measures the number of wild animals in the capture region based on an image captured by the imaging unit.

  Moreover, in the said embodiment, although the example of the structure which determines a capture | capture estimated number of heads by the control part was shown, this invention is not limited to this. In the present invention, a configuration in which the number of expected catches is determined by the user may be employed.

  In the above embodiment, when the number of wild animals in the capture area is equal to or greater than the maximum number of animals expected to be captured (second number of expected animals), the minimum number of animals expected to be captured (first number of animals expected to be captured), and Although an example of a configuration in which the standby time is set to 5 seconds, which is shorter than the case of less than the maximum number of expected catches, the present invention is not limited to this. In the present invention, when the number of wild animals in the capture region is equal to or greater than the maximum number of animals expected to be captured (second number of animals expected to be captured), no waiting time may be set (the waiting time is zero seconds).

  Further, in the above embodiment, when the number of wild animals in the capture region is equal to or greater than the maximum number of expected capture (second capture potential), the minimum number of potential capture (first capture potential), and Although an example of a configuration in which different waiting times are set for each of the cases where the number is less than the maximum number of expected catches is shown, the present invention is not limited to this. In the present invention, based on the number of wild animals in the capture area, a predetermined waiting time may be set uniformly when the number of the first expected number of animals to be captured is exceeded. Thus, a configuration may be used in which different waiting times are set.

  Moreover, although the example of the structure which records the maximum number of heads (maximum number of individuals) of the day in the confirmation mode processing has been described in the above embodiment, the present invention is not limited to this. In the present invention, the maximum number of animals (maximum number of individuals) of the day may be recorded in both the confirmation mode process and the capture mode process.

  Moreover, in the said embodiment, although the process operation | movement of the control part was demonstrated using the flow drive type flowchart which processes in order along a process flow for convenience of explanation, this invention is not limited to this. In the present invention, the processing operation of the control unit may be performed by event-driven (event-driven) processing that executes processing in units of events. In this case, it may be performed by a complete event drive type or a combination of event drive and flow drive.
