[0009] Hereinafter, embodiments of the present invention will be described with reference to the drawings. For convenience, the same reference numerals are used to designate the same or corresponding components.

[0010] FIG. 1 is a diagram showing an example of the configuration of an animal prevention system 100. The animal prevention system 100 of this embodiment is operated in a target area, a farm field, to prevent agricultural crops being grown in the field from being damaged by animals such as vermin and birds. However, the animal prevention system 100 can also be operated in target areas other than farm fields to prevent damage by animals. The animal prevention system 100 is equipped with a control device 1, multiple operating devices 2, and multiple detection devices 3.

[0011] The control device 1 is a computer or server located in a farm field or outside the farm field, or a computer or server installed in a cloud system. The control device 1 includes a processor 11, a memory 12, a communication device 13, and a user interface (referred to as "UI" in FIG. 1) 14.

[0012] The processor 11 is, for example, a CPU (Central Processing Unit), but may be configured as an arithmetic processing device other than a CPU. The memory 12 is a volatile or non-volatile memory. The memory 12 stores software programs executed by the processor 11. The memory 12 also stores various types of information and data in a readable and writable manner. Instead of the memory 12, other information storage devices may be provided in the control device 1.

[0013] The communication device 13 is a communication interface and input / output device of the control device 1, and has a communication circuit for wireless communication. For example, the communication device 13 is capable of wireless communication using wireless communication standards such as Wi-Fi (Wireless Fidelity, registered trademark), BLE (Bluetooth (registered trademark) Low Energy), LPWA (Low Power, Wide Area), and LPWAN (Low-Power Wide-Area Network) of the IEEE802.11 series. Note that the communication device 13 may also be capable of wireless communication using a mobile phone communication network or a data communication network. The control device 1 communicates wirelessly with multiple actuation devices 2 via the communication device 13. The user interface 14 includes a keyboard, a mouse, a microphone, a speaker, a display device, and the like.

[0014] The multiple actuating devices 2 and the multiple detecting devices 3 are arranged at intervals in at least one of the target area, which is the farm field, and the periphery of the farm field. The arrangement intervals between the actuating devices 2 may be regular or random. The arrangement intervals between the detecting devices 3 may also be regular or random. In this embodiment, the actuating devices 2 and the detecting devices 3 are integrally provided in a one-to-one relationship, but the actuating devices 2 and the detecting devices 3 may be separate entities.

[0015] The actuators 2 generate at least one of sound, light, and mechanical movement to stimulate the animal. The control device 1 controls the plurality of actuators 2 by transmitting operation commands to the plurality of actuators 2. The actuator 2 includes a processor 21, a memory 22, a communication device 23, an output device 24, a battery 25, and a power generation device 26.

[0016] The processor 21 of the actuation device 2 is also a CPU, but may be configured as an arithmetic processing device other than a CPU. The processor 21 is a controller of the actuation device 2. The memory 22 is a volatile or non-volatile memory. Various types of information and data are stored in the memory 22 in a readable and writable manner.

[0017] The communication device 23 is a communication interface and information input / output device of the actuation device 2, and has a communication circuit for wireless communication. The wireless communication standard of the communication device 23 is the same as that of the communication device 13 of the control device 1. The actuation device 2 communicates wirelessly with the control device 1 and other actuation devices 2 via the communication device 23. As another example, the control device 1 and multiple actuation devices 2 may communicate with each other via a wired connection.

[0018] The output device 24 is an output source of the actuation device 2 and includes at least one of a sound output device, a light emitting device, and a movement mechanism. The sound output device includes a memory that stores sound data and a speaker. The light emitting device includes a light source such as a light, an LED, or a laser irradiation device. The movement mechanism includes an actuator.

[0019] For example, if the output device 24 includes a sound output device, based on sound data stored in a memory provided in the sound output device, a speaker outputs intimidating sounds such as the barking of a guard dog, the sound of a guard dog moving, the voice of another animal (for example, an animal larger than a guard dog, or even a human), the sound of another animal moving, a siren, the sound of a gunshot, or the sound of an explosion. This creates the impression that animals are present in the field or around the field, and frightens or intimidates animals (vermin, pest birds, etc.) that appear in the field or around the field. Furthermore, because guard dogs are natural enemies of vermin, it is effective to output the barking and moving sounds of a guard dog.

[0020] Furthermore, if the output device 24 includes a light emitting device, the light source of the light emitting device emits light such as flash light, LED light, or laser beam, thereby creating the illusion of the presence of animals in or around the field, and surprising or intimidating animals that appear in or around the field.

[0021] Furthermore, if the output device 24 includes a motion mechanism, an actuator such as an electric motor, an electric cylinder, or a vibrator provided in the motion mechanism is activated, causing the motion mechanism to move surrounding objects and generate sound.

[0022] More specifically, as shown in FIG. 2, for example, the motion mechanism of the output device 24 may include a stake 24a, an electric motor (actuator) 24b, and a movable member 24c. The stake 24a is erected on the ground. The electric motor 24b is attached to the stake 24a. The movable member 24c is, for example, a whip or a board, and is connected to the rotation shaft of the electric motor 24b via a connecting member 24d. When the electric motor 24b is driven to rotate, the movable member 24c rotates and beats surrounding grass, plants such as crops, or other objects, causing the grass to move and generating sound. Note that instead of the electric motor 24b, other actuators such as an electric cylinder or a vibrator may be used. Furthermore, the position and number of the movable members 24c may be configured to be changeable.

[0023] 3, for example, grass or the like around the movable member 24f provided in the motion mechanism of the output device 24 may be attached to the movable member 24f. The movable member 24f is connected to a vibrator (actuator) 24e via a connecting member 24g. The vibrator 24e is attached to a stake 24a. The grass or the like around the movable member 24f is tied to the movable member 24f. The movable member 24f is held by the movable member 24f or is gripped by the movable member 24f. When the vibrator 24e vibrates, the movable member 24f and the grass around it vibrate (linear motion), causing the grass to move and generate sound. Note that other actuators such as an electric motor or an electric cylinder may be used instead of the vibrator 24e. Also, the position and number of the movable members 24f may be configured to be changeable.

[0024] By configuring the movement mechanism of the output device 24 as described above, it is possible to create the impression that animals are present in the field or around the field, and to startle or intimidate any animals that appear in the field or around the field.

[0025] The above-described configurations of the output device 24 that generate sound, light, and mechanical movement are merely examples, and the present invention is not limited to these configurations. The above-described configurations of the output device 24 that generate sound, light, and movement may be combined as appropriate, or other configurations may be employed in the output device 24. Furthermore, at least one of the above-described configurations of the output device 24 that generate sound, light, and movement may be combined as appropriate with other configurations.

[0026] 1 is a power source. Each part of the actuator 2 is driven by the power stored in the battery 25. The power generation device 26 is, for example, a solar panel. The power generated by the power generation device 26 is stored in the battery 25.

[0027] The detection device 3 is, for example, an infrared sensor or an infrared camera, and detects animals. The installation position, orientation, and detection sensitivity of the detection device 3 may be set so as to detect a specific animal, such as a palm civet. The detection device 3 is powered by power stored in a battery 25. Since multiple detection devices 3 are placed at intervals in the field (target area) and around the field (external area), animals that appear in the field and around the field are detected by the multiple detection devices 3.

[0028] When the detection device 3 detects an animal, it outputs a detection signal indicating the detection result to the integrated actuation device 2. Based on the detection signal output from the integrated detection device 3, the processor 21 of the actuation device 2 generates detection information indicating that the detection device 3 has detected an animal (detection result), and transmits the detection information to the control device 1 via the communication device 23. The control device 1 (processor 11) receives the detection information of the detection device 3 via the communication device 13, and determines that an animal has been detected based on the received detection information.

[0029] The control device 1 also determines the location of the animal based on the detection information of the detection device 3 that detected the animal. Specifically, when generating detection information of the integrated detection device 3, the processor 21 of the actuating device 2 includes the identification information of the actuating device 2 stored in the memory 22 in the detection information. The memory 12 of the control device 1 stores, in association with each other, identification information of the multiple actuating devices 2 and position information indicating the locations of the multiple actuating devices 2 and the detection device 3. When the control device 1 receives detection information of the detection device 3 via the communication device 13, it reads from the memory 12 the position information corresponding to the identification information of the actuating device 2 included in the received detection information, and determines the position indicated by the read position information as the location of the animal. In other words, the control device 1 determines the location of the object from the position information of the detection device 3 that detected the animal.

[0030] The control device 1 (processor 11) transmits operation commands and stop commands to each of the multiple actuation devices 2 via the communication device 13. When the communication device 23 receives an operation command from the control device 1, the processor 21 of the actuation device 2 activates the output device 24. As a result, at least one of sound, light, and mechanical movement is generated from the output device 24. Furthermore, when the communication device 23 receives a stop command from the control device 1, the processor 21 stops the output device 24. As a result, the output device 24 no longer generates sound, light, and mechanical movement.

[0031] The memory 12 of the control device 1 stores position information of a plurality of actuating devices 2. The control device 1 (processor 11) determines, based on the position information of the plurality of actuating devices 2, a plurality of actuating devices 2 to be operated from among the plurality of actuating devices 2 as a plurality of valid actuating devices 2, and operates the plurality of valid actuating devices 2 in a predetermined operation pattern. Furthermore, when an animal is detected by at least one of the plurality of detection devices 3, the control device 1 determines a plurality of valid actuating devices 2 based on the position of the animal and the position information of the plurality of actuating devices 2, and operates the plurality of valid actuating devices 2 in a predetermined operation pattern.

[0032] In addition, area information regarding the target area may be stored in memory 12, and the control device 1 may refer to the area information to determine multiple effective operating devices 2 and operate the multiple effective operating devices 2 in a predetermined operating pattern.

[0033] Fig. 4 is a flowchart showing an example of the operation of the animal prevention system 100 of the first embodiment. Each step in Fig. 4 is executed by the processor 11 of the control device 1 in accordance with a software program stored in the memory 12. (The same applies to each step in other flowcharts described later.) Figs. 5 to 10 are diagrams showing an example of the state of the operating device 2 and the detection device 3 of the first embodiment.

[0034] In the first embodiment, the control device 1 determines multiple valid operating devices 2 based on the position of the animal and the position information of the multiple operating devices 2, and operates the multiple valid operating devices 2 in a first operation pattern that is a predetermined operation pattern for repelling animals. That is, in the first embodiment, the multiple operating devices 2 act as a virtual guard dog (virtual animal) to repel animals from the field, which is the target area to be protected.

[0035] First, as a preparation step, an operator places a plurality of operating devices 2 and detecting devices 3 at intervals around the periphery of the field H, as shown in FIG. 5, for example (installation step). The operating devices 2 and detecting devices 3 may be placed within the field H. In addition, an operator operates the user interface 14 to store area information indicating the position and contours (e.g., coordinates) of the field H and the placement positions of the plurality of operating devices 2 and detecting devices 3 in the memory 12 of the control device 1 (registration step).

[0036] After the operation of the animal prevention system 100 has begun, when the control device 1 detects an animal using one of the multiple detection devices 3 (S1 in FIG. 4), it determines the animal's location Q1 (FIG. 5) based on the detection information of the detection device 3 that detected the animal (S2). At this time, the control device 1 determines the animal's location Q1 based on the detection information of the detection device 3 received by the communication device 13 as described above.

[0037] Then, the control device 1 identifies the operating device 2 that is closest to a position that is a first predetermined distance away from the animal's position Q1, and determines the position of that operating device 2 as the initial position Ps of the virtual guard dog (S3 in FIG. 4, FIG. 5). The control device 1 also identifies the operating device 2 that is closest to the animal's position Q1, and determines the position of that operating device 2 as the target position Pg to which the virtual guard dog should run (move) (S4 in FIG. 4, FIG. 5). At this time, the control device 1 identifies the operating device 2 integrated with the detection device 3 that detected the animal as the closest operating device 2.

[0038] Next, as shown in Fig. 6, for example, the control device 1 connects the initial position Ps and the target position Pg with a straight line J1, and determines the multiple operating devices 2 located inside a boundary R1 (inside the rectangle indicated by the dashed line and the dot-dash line) that is a second predetermined distance away from the straight line J1 outside the field H as the valid operating devices 2A to be activated (S5 in Fig. 4). At this time, the operating device 2 located at the initial position Ps and the operating device 2 located at the target position Pg are also determined as the valid operating devices 2A. Furthermore, the control device 1 creates the shortest travel route L1 of the virtual guard dog that passes through the multiple valid operating devices 2A in order of proximity from the initial position Ps and heads to the target position Pg (S6 in Fig. 4).

[0039] Then, the control device 1 first transmits an operation command to the valid actuation device 2A located at the initial position Ps according to the travel route L1 of the virtual guard dog, and operates the valid actuation device 2A (S7 in FIG. 4). That is, the output device 24 provided in the valid actuation device 2A generates sound, light, and mechanical movement to give the impression of the presence of the virtual guard dog. In particular, the presence of the virtual guard dog is more effectively given by outputting the barking sound of the guard dog from the sound output device included in the output device 24, or by operating a movement mechanism to move surrounding grass and the like to generate sound.

[0040] When a predetermined time has elapsed since the control device 1 sent an operation command to any valid actuation device 2A (S8), the control device 1 checks whether the animal is no longer being detected by the multiple detection devices 3. The predetermined time in step S8 may be set to a time that takes into account the moving speed of the virtual guard dog. If an animal is detected by any of the detection devices 3 (S9: NO), the control device 1 re-determines the animal's position Q1 and identifies the actuation device 2 that is closest to the animal's position Q1. If the placement position of the identified actuation device 2 is the same as the target position Pg, the control device 1 determines that the actuation device 2 that is closest to the animal's position Q1 has not changed (S10: NO).

[0041] Next, the control device 1 checks whether the valid actuated device 2 at the target position Pg has been actuated. At this time, if an actuation command has not been sent to the valid actuated device 2 at the target position Pg, the control device 1 determines that the valid actuated device 2 has not yet actuated (S11: NO). Then, the control device 1 sends an actuation command to the next valid actuated device 2A according to the travel route L1 of the virtual guard dog, actuates the valid actuated device 2A (S7), and executes the subsequent steps S8 and S9.

[0042] In this case, when a predetermined time has elapsed since the control device 1 sent an operation command to one valid activation device 2A, it sends a stop command to that valid activation device 2A and then sends an operation command to the next valid activation device 2A. As a result, the valid activation device 2A that had been operating until then stops at the timing when the next valid activation device 2A starts operating.

[0043] As described above, the control device 1 transmits operation commands to the multiple valid operating devices 2A in sequence via the communication device 13, and operates the multiple valid operating devices 2A in sequence from the initial position Ps to the target position Pg. That is, as shown in Figures 7A to 7C, for example, the control device 1 operates (ON) the multiple valid operating devices 2A in a first operation pattern that operates the multiple valid operating devices 2A in sequence from the valid operating device 2A located far from the animal's position Q1 (initial position Ps) to the valid operating device 2A located close to the animal's position Q1 (target position Pg) ("ON" in Figures 7A to 7C).

[0044] Furthermore, the control device 1 continues to operate the multiple effective operating devices 2A in the first operation pattern until the animal is no longer detected by the detection device 3. This creates an appearance in which the virtual guard dog runs along the running route L1, and an animal that appears around the field H is chased by the virtual guard dog.

[0045] On the other hand, if an animal is detected by any of the detection devices 3 (S9: NO), the control device 1 identifies the actuating device 2 closest to the re-determined animal's position Q1, and then if the position of the identified actuating device 2 differs from the target position Pg, it determines that the actuating device 2 closest to the animal's position Q1 has changed (S10: YES). In this case, the control device 1 repeatedly executes step S4 and subsequent steps.

[0046] As a result, the control device 1 updates the target position Pg, the multiple effective operating devices 2A, and the running route L1 of the virtual guard dog in accordance with the movement of the animal's position Q1, as shown in FIG. 8, and 8, the animal has moved to the vicinity of the actuator 2B, so the target position Pg is updated to the position of the actuator 2B, the actuator 2B is added to the valid actuator 2A, and the running route L1 of the virtual guard dog is extended to the position of the actuator 2B.

[0047] Furthermore, when the control device 1 determines that the actuator 2 located closest to the animal's position Q1 has not changed (S10: NO), and sends an operation command to the valid actuator 2 located at the target position Pg and determines that the valid actuator 2 has operated (S11: YES), it creates a new running route L2 for the virtual guard dog near the target position Pg (S12).

[0048] At this time, the control device 1 identifies a predetermined number of multiple actuating devices 2 in order of proximity to the target position Pg, for example, as shown in Fig. 9, and determines the identified multiple actuating devices 2 and the actuating device 2 at the target position Pg as new multiple valid actuating devices 2A. Then, the control device 1 creates a new running route L2 for the virtual guard dog so as to travel back and forth between the new multiple valid actuating devices 2A.

[0049] 4, the control device 1 operates the valid operating device 2A according to the new virtual guard dog's travel route L2, and repeatedly executes steps S8 and S9. As a result, the target position Pg and the multiple valid operating devices 2 in the vicinity of the target position Pg are repeatedly operated one by one. The virtual guard dog then appears to move back and forth along the travel route L2, and an animal in the vicinity of the target position Pg is cornered by the virtual guard dog.

[0050] As another example, the control device 1 may determine that the valid actuator 2 at the target position Pg has been operated (S11: YES), and determine a predetermined number of actuators 2 in order of proximity to the target position Pg and the actuator 2 at the target position Pg as new valid actuators 2A, and then operate the new valid actuators 2A one by one randomly.

[0051] When the animal leaves the field H and the surrounding area of ​​the field H and is no longer detected by the multiple detection devices 3 (S9: YES in Figure 4), the control device 1 stops the multiple effective operating devices 2 from operating in the first operating pattern (S13) and sets the multiple effective operating devices 2A as normal operating devices 2.

[0052] As another example, the control device 1 may determine an initial position Ps and a target position Pg, then operate the valid actuated device 2A at the initial position Ps, determine the next valid actuated device 2A during this operation, and while the next valid actuated device 2A is operating, determine yet another valid actuated device 2A, repeating this process to gradually extend the running route L1 of the virtual guard dog. In this case, the control device 1 may determine multiple valid actuated devices 2A so that the running route L1 with the shortest distance from the initial position Ps to the target position Pg is created, or may determine multiple valid actuated devices 2A so that a random running route L1 is created taking into account fluctuations, such as swaying in a direction perpendicular to the direction from the initial position Ps to the target position Pg.

[0053] For example, as shown in Fig. 10, the control device 1 connects the position of the active effective operating device 2A (the current position of the virtual guard dog) and the target position Pg (the position closest to the animal) with a straight line J1. Next, the control device 1 sets a semicircular area R2 of a predetermined radius centered on the position of the active effective operating device 2A and extending toward the target position Pg. The chord of the semicircular area R2 is set perpendicular to the straight line J1.

[0054] Next, the control device 1 extracts the actuators 2 that are in the region R2. If there are no actuators 2 that are in the region R2, the control device 1 expands the radius of the region R2, expands the region R2, and extracts the actuators 2 that are in the expanded region R2. At this time, the control device 1 extracts only one actuator. When the actuator 2 is extracted, the actuator 2 is determined as the valid actuator 2A to be operated next.

[0055] Furthermore, when multiple actuators 2 are extracted, the control device 1 weights the multiple actuators 2 based on the distance from the positions of the multiple actuators 2 to the line J1. For example, as shown in Fig. 10, if there are two actuators 2C and 2D in area R2, the control device 1 applies the distances c and d from each actuator 2C and 2D to the line J1 to the following equation to calculate weight values ​​E(c) and E(d) for each actuator 2C and 2D. The weight value is the probability (expected value) of the next operation. E(c)=1 / c÷(1 / c+1 / d) E(d)=1 / d÷(1 / c+1 / d)

[0056] According to the above calculation formula, the weight value E(d) of the actuator 2D located closer to the line J1 is greater than the weight value E(c) of the actuator 2C located farther away than the actuator 2D. Then, the control device 1 determines the valid actuator 2A to be operated next based on the extracted weight values ​​E(c) and E(d) of the multiple actuators 2C and 2D and a predetermined random number.

[0057] For example, if c is 2m and d is 1m, E(c) is 33% and E(d) is 67%. The control device 1 allocates 1 to 19 seconds, which corresponds to the first 33% of the 1 minute (60 seconds) range of the random number, to the time when actuating device 2C should be determined, and allocates 20 to 60 seconds, which corresponds to the remaining 67%, to the time when actuating device 2D should be determined. Then, if the number of seconds of the current time, which is the seed of the random number, falls between 1 and 19 seconds, the control device 1 determines actuating device 2C as the valid actuating device 2A, and if the number of seconds of the current time falls between 20 and 59 seconds, the control device 1 determines actuating device 2D as the valid actuating device 2A.

[0058] As a result of the above, the operating device 2 closest to the straight line J1 is not necessarily determined as the valid operating device 2A, but one of the operating devices 2 located within the region R2 is randomly determined as the valid operating device 2A. In this way, the valid operating device 2A is determined as needed up to the target position Pg, thereby creating a randomly fluctuating travel route L1 (FIG. 10) from the initial position Ps to the target position Pg.

[0059] The above-described formula for calculating the weight value is an example, and the weight value may be calculated using a formula or method other than the above-described formula. Furthermore, the above-described 60 seconds is an example of a random number, and another time (e.g., milliseconds) or a value other than time (e.g., wind speed in the field H measured by a sensor) may be used as the random number. Furthermore, at least one of the formula for calculating the weight value and the random number may be set so that the closer an operating device 2 is to the straight line J1, the more likely it is to be determined as the effective operating device 2A.

[0060] Fig. 11 is a flowchart showing an example of the operation of the animal prevention system 100 of the second embodiment. Figs. 12 to 14 are diagrams showing an example of the state of the actuation device 2 and the detection device 3 of the second embodiment.

[0061] In the second embodiment, the control device 1 determines multiple valid operating devices 2 based on a predetermined position included in the area information and the position information of the multiple operating devices 2, and operates the multiple valid operating devices 2 in a second operation pattern that drives the animal to the predetermined position. That is, in the second embodiment, the multiple operating devices 2 act as a virtual guard dog to guide the animal to the predetermined position.

[0062] First, as a preparation step, an operator places a plurality of operating devices 2 and detecting devices 3 at intervals in and around the field H, as shown in FIG. 12 (installation step). The operating devices 2 and the detection devices 3 may be placed only around the periphery of the field H. Also, the operator operates the user interface 14 to store area information indicating the position, outline, and predetermined positions where traps and the like are placed of the field H, as well as the placement positions of the plurality of operating devices 2 and detection devices 3, in the memory 12 of the control device 1 (registration process).

[0063] After the animal prevention system 100 starts operation, the control device 1 reads out a predetermined position from the area information and determines the predetermined position as the target position Pq to which the animal will be chased (S21 in FIG. 11, FIG. 12). After that, when the control device 1 detects an animal by any of the multiple detection devices 3 (S22 in FIG. 4), it determines the animal's position Q1 based on the detection information of the detection device 3 that detected the animal (S23).

[0064] 13, the control device 1 calculates the distance from the animal's position Q1 to the target position Pq, and calculates an added value (D1+x) by adding a predetermined value x that is shorter than the calculated distance value D1 to the calculated value D1. Next, the control device 1 creates an arc U1 centered at the target position Pq and having the added value (D1+x) as its radius, and an arc U2 having the calculated value D1 as its radius, and determines one or more actuators 2 located between the arcs U1 and U2 as valid actuators 2A (S24 in FIG. 11).

[0065] If there is no actuator 2 between the arcs U1 and U2, the control device 1 increases the predetermined value x, updates the arc U1, and determines one or more actuators 2 between the updated arcs U1 and U2 as the valid actuators 2A.

[0066] Then, the control device 1 transmits an operation command to the valid operation device 2A to operate the valid operation device 2A (S25 in FIG. 11). At this time, if there are multiple valid operation devices 2A, the control device 1 transmits operation commands to the multiple valid operation devices 2A in order, and operates the multiple valid operation devices 2A one by one in order. That is, when a predetermined time has elapsed since the control device 1 transmitted an operation command to one valid operation device 2A, the control device 1 transmits a stop command to that valid operation device 2A and transmits an operation command to the next valid operation device 2A. At this time, the control device 1 may operate the multiple valid operation devices 2A in order of proximity or furthest from the field H, or may operate the multiple valid operation devices 2A randomly.

[0067] When a predetermined time has elapsed since transmitting the operation command to all valid operating devices 2A (S26), the control device 1 checks whether the animal is no longer detected by the multiple detection devices 3. The predetermined time in step S26 may also be set to a time that takes into account the moving speed of the virtual guard dog. If an animal is detected by any of the detection devices 3 (S27: NO), the control device 1 checks whether the animal has reached the target position Pq. That is, at this time, the control device 1 checks whether the animal has been caught in the trap.

[0068] For example, if a detection device 3 arranged near the target position Pq does not detect an animal, but another detection device 3 does, the control device 1 determines that the animal has not reached the target position Pq (S28: NO).The control device 1 then re-determines the animal's position Q1 based on the detection information from the detection device 3 that detected the animal (S23), and repeatedly executes the processes from step S24 onwards.At this time, if the animal's position Q1 has not moved, the control device 1 does not update the valid activation device 2A, and activates the valid activation device 2A again.

[0069] Furthermore, when the animal's position Q1 moves, the control device 1 stops the operation of the determined valid operating device 2A and sets the determined valid operating device 2A as the normal operating device 2. Then, the control device 1 recreates the arcs U1 and U2 using the procedure described above, determines the operating device 2 located on the arcs U1 and U2 as the valid operating device 2A (S24), and operates the valid operating device 2A (S25).

[0070] 14, for example, the control device 1 determines multiple valid operating devices 2A in accordance with the movement of the animal's position Q1, and operates the multiple valid operating devices 2A in order from the valid operating device 2A located far from the target position Pq (predetermined position) to the valid operating device 2A located close to the target position Pq. That is, the control device 1 operates the multiple valid operating devices 2A in a second operation pattern in which the valid operating devices 2A are operated in order from the valid operating device 2A located far from the predetermined position Pq where the trap is located (the position where the animal was first detected) to the valid operating device 2A located close to the trap. This creates the illusion of a virtual guard dog running from a position close to the animal to the predetermined position Pq where the trap is located, and a situation occurs in which an animal that appears around the field H is guided to the trap by the virtual guard dog.

[0071] Then, after a predetermined time has elapsed (S26), if a detection device 3 located near the target position Pq detects an animal (S27: NO), and the other detection devices 3 have not detected an animal, the control device 1 determines that the animal has reached the target position Pq (S28: YES). At this time, the animal is caught in the trap. In this case, the control device 1 stops the operation of the valid operating device 2 in the second operation pattern (S29), and sets the multiple valid operating devices 2A as normal operating devices 2.

[0072] Furthermore, if the animal leaves the field H and its surroundings and is no longer detected by the multiple detection devices 3 (S27: YES), the control device 1 stops the operation of the effective operating device 2 in the second operating pattern and sets the multiple effective operating devices 2A as normal operating devices 2.

[0073] As described above, the control device 1 continues to operate the multiple effective operating devices 2A in the second operation pattern until the animal is located at the target position (predetermined position where the trap is located) Pq or until the animal is no longer detected by the detection device 3.

[0074] Fig. 15 is a flowchart showing an example of the operation of the animal prevention system 100 of the third embodiment. Fig. 16 is a diagram showing an example of the state of the actuation device 2 of the third embodiment.

[0075] In the third embodiment, the control device 1 determines multiple valid operating devices 2 based on area information and position information of the multiple operating devices 2, and when a predetermined operating condition is met, operates the multiple valid operating devices 2 in a third operation pattern as a predetermined operation pattern. That is, in the third embodiment, regardless of whether an animal is detected or not, the multiple operating devices 2 act as a virtual guard dog to keep animals away from the field and its surroundings.

[0076] As described above, after workers or the like carry out the preparation process and the animal prevention system 100 begins operation, the control device 1 determines multiple effective operating devices 2A based on the position information of the multiple operating devices 2 (S31 in Figure 15), and creates a running route L1 for the virtual guard dog so that it passes through the positions where the effective operating devices 2A are located one by one, starting from the effective operating device 2A located at one end and progressing to the effective operating device 2A located at the other end (S32).

[0077] At this time, the control device 1 refers to area information, for example, and determines, from among the multiple operating devices 2 around the field H, which is the target area, the operating devices 2 that are in a specific direction, as multiple valid operating devices 2A, as shown in Fig. 16. In the example shown in Fig. 16, multiple valid operating devices 2A are determined along a part of the field H, but multiple valid operating devices 2A may also be determined to surround the field H.

[0078] Furthermore, the control device 1 may refer to area information, for example, to identify a predetermined location where a trap is located or a predetermined location where animals frequently appear, determine the position of the operating device 2 that is closest to a position that is a predetermined distance away from the predetermined location as the initial position Ps, and determine the position of the operating device 2 that is closest to the predetermined location as the target position Pg. Then, as in the first embodiment, the control device 1 may determine the position of a plurality of operating devices that are located inside a boundary that is set based on a straight line connecting the initial position Ps and the target position Pg. 2 may be determined as the valid actuated device 2A. The control device 1 may also create a travel route L1 of the virtual guard dog that passes through the multiple valid actuated devices 2A in order of proximity from the initial position Ps to the target position Pg.

[0079] Then, the control device 1 operates the multiple valid operating devices 2A one by one in order from the valid operating device 2A at the initial position Ps to the valid operating device 2A at the target position Pg according to the travel route L1 of the virtual guard dog (S33). That is, the control device 1 operates the multiple valid operating devices 2A in the third operation pattern. This creates the appearance of the virtual guard dog traveling along the travel route L1 in the field H.

[0080] Then, the control device 1 operates the valid actuated device 2A located at the target position Pg, and after a predetermined time has elapsed, stops that valid actuated device 2A, and then waits in a stopped state with all valid actuated devices 2A in operation (S34). Note that the predetermined time for operating each valid actuated device 2A may be set to a time that takes into consideration the moving speed of the virtual guard dog (for example, a time calculated from the moving speed of the virtual guard dog and the distance between the valid actuated devices 2A).

[0081] Thereafter, when the preset operation time arrives (S35), the control device 1 repeatedly executes the processes from step S33 onward. That is, the control device 1 again operates the multiple valid operating devices 2A according to the travel route L1 of the virtual guard dog (S33). The operation time may be a fixed time every day, or may be a time that varies depending on the day of the week, or may be a predetermined date and time.

[0082] As another example, the control device 1 may repeatedly execute the processes from step S31 onward at a preset operation time (S35). In this case, the control device 1 changes the multiple valid operation devices 2A (S31), changes the running route L1 of the virtual guard dog (S32), and operates the multiple valid operation devices 2A according to the changed running route L1 of the virtual guard dog (S33). That is, the control device 1 operates the multiple valid operation devices 2A in a third operation pattern based on a different running route L1 each time the operation time arrives. Note that the control device 1 may operate the multiple valid operation devices 2A in the third operation pattern based on an instruction from the user, separate from the operation time.

[0083] The animal prevention system 100 may be configured to be able to implement all of the first, second, and third embodiments described above, or may be configured to be able to implement one or two of them. That is, the control device 1 may be configured to be able to operate the multiple operating devices 2 in all of the first, second, and third operation patterns described above, or may be configured to be able to operate the multiple operating devices 2 in one or two of them.

[0084] Furthermore, when the control device 1 is configured to be able to operate the multiple actuating devices 2 in two or more patterns of the first, second, and third actuating patterns, for example, the control device 1 may be configured to be able to set the conditions for executing each actuating pattern via the user interface 14 or the like, and the set conditions may be associated with area information and stored in the memory 12. Then, when any of the conditions is met, the control device 1 may operate the multiple actuating devices 2 in the corresponding actuating pattern.

[0085] Also, for example, the first embodiment described above may be implemented as a repelling mode, the second embodiment as a driving mode, and the third embodiment as a deterrent mode, and each may be implemented in the animal prevention system 100. The system may be configured so that the user can select at least one of the repelling mode, driving mode, and deterrent mode by using the user interface 14 or the like, and the control device 1 executes the selected mode. Alternatively, the control device 1 may be configured so that the user can select at least one of the repelling mode, driving mode, and deterrent mode by using the user interface 14 or the like, and the control device 1 executes the selected mode. The device 1 may be configured to, when a predetermined condition is met, execute one of the chasing mode, chasing mode, and checkmate mode corresponding to the condition.

[0086] Furthermore, the control device 1 may store information indicating the multiple valid operating devices 2 operated in either the first operation pattern or the second operation pattern in association with information indicating the travel route L1 or the operation order of the multiple valid operating devices 2 as an operation history in the memory 12. Thereafter, when the control device 1 operates the multiple operating devices 2 in the third operation pattern, the control device 1 may read the operation history from the memory 12 and operate the multiple valid operating devices 2 indicated in the operation history along the travel route L1 or in the operation order.

[0087] In the above-described embodiment, the control device 1 transmits operation commands and stop commands to the multiple valid activation devices 2A to activate or stop the multiple valid activation devices 2A, but this configuration is not limited to this. For example, the control device 1 may transmit order information indicating the order in which the multiple valid activation devices 2A will operate or information about travel routes L1, L2 to each of the multiple valid activation devices 2A, and the multiple valid activation devices 2A may operate in order based on the order information or travel routes L1, L2. In this case, for example, based on the order information or travel routes L1, L2, one valid activation device 2A may operate and, when it stops after a predetermined time, stop information indicating that the one valid activation device 2A has stopped may be transmitted to the next valid activation device 2A, and the next valid activation device 2A may operate after receiving the stop information. In this way, the multiple valid activation devices 2A may communicate with each other and operate one after another.

[0088] In the above-described embodiment, an example has been shown in which the control device 1 is configured separately from the multiple actuation devices 2. However, for example, the processor 21 provided in any one of the multiple actuation devices 2 may constitute the control device 1. Or, the processor 21 provided in each of the multiple actuation devices 2 may constitute the control device 1. In this case, the multiple valid actuation devices 2A determined by the multiple actuation devices 2 and the operation order or travel route of the valid actuation devices 2A will be the same. For this reason, for example, based on the operation order or travel route of the multiple valid actuation devices 2A, the multiple valid actuation devices 2A may be configured to communicate with each other and operate one after another, such that when one activated valid actuation device 2A stops, stop information is transmitted to the next valid actuation device 2A, and the next valid actuation device 2A operates after receiving the stop information.

[0089] In the above-described embodiment, an example is shown in which the actuator 2 and the detector 3 are integrated, and the processor 21, the communication device 23, the battery 25, etc. are used for both the actuator 2 and the detector 3, but the actuator 2 and the detector 3 may not be integrated and may be arranged spatially apart.

[0090] Furthermore, a dedicated processor, memory, communication device, battery, and power generation device may be provided for the detection device 3. In this case, when the processor of the detection device 3 transmits detection information of the detection device 3, the detection information may include identification information of the detection device 3 stored in the memory. Furthermore, the memory 12 of the control device 1 may store identification information of multiple detection devices 3 and location information indicating the locations where the multiple detection devices 3 are located, in association with each other. Then, when the control device 1 receives detection information of the detection device 3 via the communication device 13, it may read from the memory 12 the location information corresponding to the identification information of the detection device 3 included in the received detection information, and determine the location indicated by the read location information as the location of the animal.

[0091] Furthermore, the detection devices 3 do not have to be provided in one-to-one correspondence with the actuation devices 2. The number of detection devices 3 installed may be greater than or less than the number of actuation devices 2 installed, or may be the same as the number of actuation devices 2 installed.

[0092] Alternatively, a single detection device 3 made up of, for example, an imaging device may be used to detect animals present in the field H (target area) and around the field H. The imaging device may be, for example, a CCD ( Alternatively, a CCD camera equipped with a Charge Coupled Devices (CCD) image sensor, a CMOS camera equipped with a CMOS (Complementary Metal Oxide Semiconductor) image sensor, or an infrared camera may be used. In this case, an image processing device that processes the data of the image captured by the imaging device may be provided in the control device 1. Then, the processor 11 of the control device 1 may process the image captured by the imaging device using the image processing device to detect the presence or absence of animals in the field H and around the field H and determine the positions of the animals.

[0093] The control device 1 may also process the image captured by the imaging device using an image processing device to determine the size and type of the detected animal.The control device 1 may then determine the multiple valid operating devices 2A, the travel route L1, and the operating time of each valid operating device 2A, taking into account the size and type of the detected animal.Also, artificial intelligence (AI) may be used to detect the position, size, and type of the animal based on the image captured by the imaging device.

[0094] The animal prevention system 100 of this embodiment described above has the configurations described in the following items and provides the effects.

[0095] [Item 1] The animal prevention system 100 comprises a plurality of actuators 2 that generate at least one of sound, light, and mechanical movement, and a control device 1 that determines, based on position information of the plurality of actuators 2, a plurality of actuators 2 that should be operated from among the plurality of actuators 2 as a plurality of effective actuators 2A, and operates the plurality of effective actuators 2A in a predetermined operation pattern.

[0096] With the configuration of the above item 1, the multiple valid operating devices 2A are generated in a predetermined operation pattern, making it difficult for animals such as pests to become accustomed to the operations of the multiple valid operating devices 2A, and it is possible to exterminate animals from the target area H where the multiple operating devices 2 are arranged. This makes it possible to prevent damage caused by animals in the target area H. For example, the damage can be prevented for a long period of time.

[0097] [Item 2] The animal prevention system 100 described in Item 1 above is equipped with a detection device 3 that detects animals present in the target area H and the surroundings of the target area H, and the control device 1 determines the animal's position Q1 from the detection result of the detection device 3, and determines multiple effective operating devices 2A based on the animal's position Q1 and the position information of the multiple operating devices 2, and operates the multiple effective operating devices 2A in a predetermined operating pattern.

[0098] With the configuration of item 2 above, each time an animal is detected, multiple effective operating devices 2A operate in a specific operating pattern according to the animal's position Q1, making it more difficult for animals to become accustomed to the operations of the multiple effective operating devices 2A, and animals can be more effectively exterminated from the target area H.

[0099] [Item 3] In the animal prevention system 100 described in Item 2 above, multiple detection devices 3 are arranged at intervals in at least one of the target area H and the periphery of the target area H, and the control device 1 determines the animal's position Q1 from the position information of the detection device 3 that detected the animal.

[0104] By configuring item 5 above, it is possible to make it appear as if a virtual guard dog, modeled after a guard dog that is a natural enemy of pests, is approaching an animal, thereby effectively driving the animal away from the target area H.

[0105] [Item 6] In the animal prevention system 100 described in item 4 or 5 above, the control device 1 updates the multiple effective operating devices 2A in accordance with the movement of the animal's position Q1, and operates the updated multiple effective operating devices 2A in the first operating pattern.

[0106] The configuration of item 6 above makes it possible to repel animals accurately even if the animals move.

[0107] [Item 7] In the animal prevention system 100 described in any one of items 4 to 6 above, the control device 1 continues to operate the multiple effective operating devices 2A in the first operation pattern until the detection device 3 no longer detects an animal.

[0108] The configuration of item 7 above makes it possible to reliably repel animals from the target area H and its surroundings.

[0109] [Item 8] In the animal prevention system 100 described in Item 2 above, the control device 1 operates the multiple effective operating devices 2A in a second operation pattern that drives the animal into a predetermined position Pq as a predetermined operation pattern.

[0110] The configuration of item 8 above creates the appearance of a virtual guard dog, which can drive animals into a predetermined position Pq where a trap or the like is located, making it possible to prevent damage caused by animals in the target area H for a long period of time.

[0111] [Item 9] In the animal prevention system 100 described in Item 8 above, the second operation pattern is an operation pattern in which the multiple effective operating devices 2A are operated in sequence, starting from the effective operating device 2A that is located close to the animal's position Q1 and far from the specified position Pq, to ​​the effective operating device 2A that is located close to the specified position Pq.

[0112] The configuration of item 9 above allows the virtual guard dog to guide the animal toward the predetermined position Pq, thereby effectively driving the animal into the predetermined position.

[0113] [Item 10] In the animal prevention system 100 described in item 8 or 9 above, the control device 1 continues to operate the multiple effective operating devices 2A in the second operation pattern until the animal is located at the predetermined position Pq.

[0114] The configuration of item 10 above makes it possible to reliably drive the animal into the predetermined position Pq.

[0115] [Item 11] In the animal prevention system 100 described in any one of items 8 to 10 above, the control device 1 continues to operate the multiple effective operating devices 2A in the second operation pattern until the animal is no longer detected by the detection device 3.

[0116] The configuration of item 11 above makes it possible to repel animals from the target area H and its surroundings.

[0117] [Item 12] In the animal prevention system 100 described in Item 1 above, when a predetermined operating condition is met, the control device 1 operates the multiple effective operating devices 2A in a third operating pattern as a predetermined operating pattern.

[0118] The configuration of item 12 above makes it possible to deter animals from approaching the target area H, thereby preventing damage caused by animals in the target area H for a long period of time.

[0119] [Item 13] In the animal prevention system 100 described in any one of items 1 to 13 above, the predetermined operation pattern is a pattern that presents the virtual animal by outputting at least one of the voice and moving sound of the virtual animal from the multiple effective operating devices 2A.

[0120] With the configuration of the above item 13, it is possible to make the barking and moving sounds of a virtual guard dog output from the multiple effective operating devices 2A in response to animals such as pests that appear in the target area H and the surrounding area of ​​the target area H, thereby making it appear as if the virtual guard dog is approaching the animals. This makes it possible to more effectively exterminate animals from the target area H and the surrounding area of ​​the target area H.

[0121] [Item 14] In the animal prevention system 100 described in any one of items 1 to 12 above, the predetermined operation pattern is a pattern in which the multiple effective operating devices 2A are mechanically moved to move objects around the multiple effective operating devices 2A, thereby creating the appearance of a virtual animal.

[0122] The configuration of item 14 above makes it possible to more effectively present virtual animals modeled after guard dogs, natural enemies of vermin. This makes it possible to more effectively exterminate animals from a target area where multiple operating devices 2 are placed. Furthermore, because objects around multiple valid operating devices 2A are used, there is no need to prepare separate objects to move, reducing the burden of preparation work.

[0123] [Item 15] In the animal prevention system 100 described in any one of items 1 to 14 above, the multiple operating devices 2 are arranged at intervals in at least one of a target area, which is one or more fields H where crops are grown, and the periphery of the fields H, and generate at least one of sound, light, and mechanical movement to stimulate animals that harm the crops.

[0124] With the configuration of item 15 above, animals such as vermin can be effectively exterminated from the field H by operating the multiple operating devices 2 in a predetermined operation pattern.

[0125] [Item 16] In the animal prevention system 100 described in Item 3 above, the multiple operating devices 2 are arranged at intervals in at least one of the target area H and the periphery of the target area H.

[0126] With the configuration of item 16 above, animals can be easily removed from the target area H by operating the multiple operating devices 2 in a predetermined operation pattern.

[0127] [Item 17] In the animal prevention system 100 described in any one of items 2 to 16 above, the detection device 3 and the actuation device 2 are integrally configured.

[0128] The configuration of the above item 17 reduces the burden on the worker when placing the detector 3 and the actuator 2, and improves workability. Since the positions of the detection devices 3 and the actuators 2 are the same, the burden on the operator when registering the position information of the detection devices 3 and the actuators 2 in the control device 1 is reduced, and it is possible to reduce the amount of data for the position information of the detection devices 3 and the actuators 2. Furthermore, it is possible to reduce the processing burden when the control device 1 uses the position information of the detection devices 3 and the actuators 2.

[0129] The embodiments disclosed herein should be considered to be illustrative in all respects and not restrictive.
