[Modes for carrying out the invention]

[0007] The following describes embodiments for carrying out the invention. In this specification and each figure, elements similar to those already described are denoted by the same reference numerals, and detailed descriptions are omitted as appropriate.

[0008] (First Embodiment) First observation unit, first output unit Figure 1 is a schematic diagram representing a wildlife intrusion prevention system according to the first embodiment. Figure 2 is a schematic diagram representing the configuration of the wildlife intrusion prevention system according to the first embodiment. The wildlife intrusion prevention system 100 includes a first observation unit 101, a first output unit 111, a detection unit 103, and an output control unit 104. The detection unit 103 includes a repellent target detection unit 130 and a wildlife detection unit 131. Each component of the wildlife intrusion prevention system 100 is capable of transmitting and receiving information, and the communication network formed by these components may be connected by wire or wireless.

[0009] The first observation unit 101 is used to monitor the approach or entry of birds, animals, or objects to be avoided. Examples of target birds and animals include bears, deer, wild boars, monkeys, and crows. In this embodiment, "objects to be avoided" refers to things that birds and animals dislike and avoid, and examples of objects to be avoided include people, dogs, drones, robots, and cars. In the case of farmland, this would include workers performing agricultural work; in the case of a mega solar power plant, this would include workers entering for maintenance, inspection, etc., vehicles driven by workers, robots patrolling for inspection, and drones. The first observation unit 101 includes a camera, infrared sensor, ultrasonic sensor, and wireless device, which are connected to the first observation unit 101 by antennas for transmitting and receiving electromagnetic waves, and multiple units of these may be used in combination. In this case, the signals and data sensed and transmitted by the first observation unit 101 are input to the detection unit 103, and based on this input, the detection unit 103 detects the approach or entry of birds, animals, or objects to be avoided. For example, two standard radio transceivers could communicate with each other, and the intrusion of birds or animals could be detected between these transceivers by measuring the received power of the received signals. Examples of such transceivers include those compliant with Wi-Fi in the 5GHz or 2.4GHz band, Bluetooth in the 2.4GHz band, Wi-SUN, Zigbee, or Wi-Fi HaLow in the 920MHz band. Alternatively, radar using millimeter waves in higher frequency bands could be used.

[0010] The first observation unit 101 is installed near the boundary of an area where farmland or a mega solar power plant is located, and is installed in a manner that allows it to monitor the area near the outer boundary of these areas. Here, we will explain using the example of installing one first observation unit 101, but multiple observation units may be provided as the first observation unit 101. For example, when detecting approaching or intruding birds and animals in a large area such as a mega solar power plant, farmland, forest, or railway, multiple cameras may be installed and these may be used as the first observation unit 101.

[0011] For detecting undesirable objects, the undesirable object detection unit 130 (described later) detects them based on input from the first observation unit 101. For example, if the first observation unit 101 is a camera, the video captured by this camera is input to the undesirable object detection unit 130, and the undesirable object detection unit 130 detects the approach or intrusion of undesirable objects based on this video.

[0012] The detection unit 103 includes a repellent target detection unit 130 and a bird / animal detection unit 131.

[0013] The object to be avoided detection unit 130 determines whether an object to be avoided is approaching or entering based on the input from the first observation unit 101, and notifies the output control unit 104 of the result. For example, if the first observation unit 101 is a camera, the object to be avoided is detected based on the video information input to the first observation unit 101. One method of detection performed by the object to be avoided detection unit 130 is to use AI.

[0014] The wildlife detection unit 131 determines whether or not a wildlife to be prevented from entering is approaching based on the input from the first observation unit 101, and notifies the output control unit 104 of the result. For example, if the first observation unit 101 is a camera, wildlife is detected based on the video information input to the first observation unit 101. One method of detection performed by the wildlife detection unit 131 is to use AI. The system can be trained in advance using machine learning, for example, by using a large number of images of the target species of wildlife, and based on this, it can determine from the captured images whether the target wildlife has entered or approached. The training can be performed before the system is installed, or for a certain period after the system is installed. Alternatively, the wildlife detection unit 131 may identify these species and individuals based on the input from the first observation unit 101 and detect only the species and individuals to be prevented from entering.

[0015] The bird / animal detection unit 131 also notifies the output control unit 104 that the bird / animal has learned the first output 120 (that the bird / animal will continue to be detected in the designated area even if the first output 120 is output).

[0016] When the output control unit 104 receives a notification indicating that a repellent target has been detected from the repellent target detection unit 130, or receives a notification indicating that a bird or animal has been detected from the bird / animal detection unit 131, it issues an instruction to output a medium or substance expected to have a repellent effect (the first output 120 and the second output 220) or an instruction to stop outputting the same to the first output unit 111. The output control unit 104 also stores the contents (instructions) of the first output 120 and the second output 220 for the first output unit 111. Furthermore, when the bird / animal detection unit 131 detects the bird or animal, the output control unit 104 instructs the first output unit 111 to perform the same output that it instructed the first output unit 111 to perform when the repellent target detection unit 130 detected a repellent target in the past. In addition, the output control unit 104 may also be intentionally instructed by a human to issue an output instruction to the first output unit 111, or for example, may issue an output instruction to the first output unit 111 upon detecting that a worker has entered a predetermined area.

[0017] In addition, the output control unit 104 also determines whether to terminate the system. If it is determined that the system is to be terminated, it stops the output of the first output 120 and the second output 220, and terminates the system.

[0018] Furthermore, when the bird / animal detection unit 131 detects a bird or animal, the output control unit 104 instructs the first output unit 111 to perform the same output that it instructed the first output unit 111 to perform when the repellent target detection unit 130 detected a repellent target in the past.

[0019] The first output unit 111, when the bird / animal detection unit 131 detects a bird or animal, outputs, as the first output 120, a medium 120-1 or a substance 120-2 that causes a medium change or a substance change to at least a part of the surrounding environment of a predetermined area based on an input from the output control unit 104. In other words, when a bird or animal is detected, the first output 120 is output. Here, the predetermined area refers to an area where it is desired to prevent the approach and invasion of birds and animals, and examples include the vicinity of the boundary of an agricultural land or an area where a mega-solar power station is installed. The medium 120-1 or the substance 120-2 suppresses the invasion of birds and animals into the predetermined area. The first output 120 refers to the medium 120-1 or the substance 120-2 that has a repellent effect on birds and animals.

[0020] Furthermore, when the repellent target detection unit 130 detects a repellent target, the first output unit 111 outputs a medium 220-1 or substance 220-2 as a second output 220, based on the input of the output control unit 104, which causes a change in the medium or substance of the surrounding environment of a predetermined area. In other words, when a repellent target is detected, the second output 220 is output. The second output 220 refers to the medium 220-1 or substance 220-2 that informs birds and animals that a repellent target is actually present. The first output unit 111 may be, for example, a speaker or lighting fixture, and multiple units may be installed, or multiple types may be used in combination. The first output 120 or the second output 220 may be a gas or liquid such as water, sound waves, ultrasound, light, firecrackers, or bear repellent spray, and multiple types may be provided for one of these. The first output 120 is selected from multiple types by the output control unit 104. The second output 121 is selected from multiple types by the output control unit 104. The first output unit 111 is installed, for example, near the boundary of farmland or a mega solar power plant, so that the output reaches outside these areas. Multiple first output units 111 may be installed. In cases where the goal is to prevent birds and animals from entering vast areas such as mega solar power plants, farmland, or railway facilities, it is possible to install a large number of first output units 111.

[0021] Furthermore, even if the bird / animal detection unit 131 does not observe birds or animals, and the repellent target detection unit 130 detects a repellent target, the second output 220 may still be output around the first output unit 111. For example, when outputting sound, even if the bird / animal detection unit 131 does not detect birds or animals, there is a possibility that birds or animals are nearby. Therefore, by outputting the second output 220, the presence of a repellent target can be made known, which may improve the repellent effect.

[0022] Figure 3 is a block diagram showing an example of the hardware configuration of a bird and animal intrusion prevention system according to the first embodiment.

[0023] The output control unit 104 includes, for example, a central processing unit (CPU) 21, storage 22, a communication device 23, and random access memory (RAM) 24. The CPU 21, storage 22, communication device 23, and RAM 24 may be connected, for example, via a bus 20.

[0024] The CPU 21 is, for example, at least one processor. The CPU 21 controls the operation of various components within the output control unit 104.

[0025] Storage 22 is a storage device that includes non-volatile memory. Storage 22 can be implemented, for example, as a solid-state drive (SSD) or a hard disk drive (HDD).

[0026] The communication device 23 is a device configured to perform wired or wireless communication. The communication device 23 includes a transmitting unit that transmits signals (i.e., data and information) and a receiving unit that receives signals. The communication device is configured to communicate with the detection unit 103 and the first output unit 111, respectively, by complying with any communication method such as a wired local area network (LAN), wireless LAN, mobile communication, or Bluetooth®.

[0027] RAM24 is volatile memory. RAM24 can be implemented, for example, as dynamic random access memory (DRAM) or static random access memory (SRAM). The memory area of ​​RAM24 is allocated, for example, as storage area for the operating system (OS), drivers, and various application programs. Application programs include, for example, a wildlife damage prevention program 241.

[0028] The wildlife damage prevention program 241 is a program that uses sensor information received from the detection unit 103 to control the outputs of the first output 120 and the second output 220 from the first output unit 111. The wildlife damage prevention program 241 is loaded from storage 22 to RAM 24 at runtime, for example.

[0029] Furthermore, the memory area of ​​RAM24 may be allocated as a storage area for the medium management table 242 and the wildlife-medium management table 243. The medium management table 242 is data for managing the output contents of the first output 120 and the second output 220 output from the first output unit 111. The wildlife-medium management table 243 is data for managing the correspondence between wildlife and the output contents of the first output 120 and the second output 220 used for that wildlife. The medium management table 242 and the wildlife-medium management table 243 are loaded from storage 22 into RAM24, for example, when the wildlife damage prevention program 241 is executed.

[0030] Referring to Figures 4 and 5, the configurations of the medium management table 242 and the bird / animal-medium management table 243 will be explained.

[0031] Figure 4 shows an example of the configuration of a medium management table used in the bird and animal intrusion prevention system according to the first embodiment. The medium management table 242 includes multiple entries corresponding to multiple output contents for the first output 120 and the second output 220, respectively. Each of the multiple entries includes, for example, an output ID field, a type field, a pattern field, a wavelength field, and a frequency field.

[0032] In an entry corresponding to a particular output, the Output ID field indicates a unique identifier (Output ID) that identifies that output. In other words, the Output ID field is set to the Output ID assigned to the corresponding output.

[0033] The type field indicates the type of first output 120 and second output 220 (i.e., medium 120-1, substance 120-2, medium 220-1, substance 220-2) used in the corresponding output content. The type field may be set to a single medium or substance, such as "sound wave" or "light". Alternatively, the type field may be set to a combination of multiple media or substances, such as "sound wave / light".

[0034] The pattern field indicates the pattern used for the corresponding output content. For example, if sound waves are used as the medium, the pattern field will be set to the time-series output pattern (time waveform data) of the sound waves. Similarly, if light is used as the medium, the pattern field will be set to the time-series output pattern (emission pattern) of the light.

[0035] The wavelength field indicates the wavelength of light used in the corresponding output. Specifically, when light is used as the medium, the wavelength field is set to the wavelength of that light. If light is not used as the medium, no value is set in the wavelength field.

[0036] The frequency field indicates the frequency of the sound wave used in the corresponding output. Specifically, when a sound wave is used as the medium, the frequency of that sound wave is set in the sound wave field. If a sound wave is not used as the medium, no value is set in the wavelength field. The pattern field may also be set to the frequency pattern used in the corresponding output.

[0037] In the example shown in Figure 4, the output content corresponding to output ID "000" is specified as outputting a sound wave with frequency F1 using output pattern A. The output content corresponding to output ID "001" is specified as outputting a sound wave with frequency F2 using output pattern B. The output content corresponding to output ID "002" is specified as outputting a sound wave with frequency F2 using output pattern A, and also outputting light with wavelength W1 using emission pattern A. Furthermore, the output content corresponding to output ID "035" is specified as outputting light with wavelength W1 using emission pattern B.

[0038] With the configuration of the medium management table 242 described above, the bird and animal intrusion prevention system 100 (more specifically, the output control unit 104) can manage the output content of various media or substances. Note that the configuration of the medium management table 242 shown in Figure 3, and the output content of the media or substances managed by the medium management table 242, are just examples. The medium management table 242 can be any format of information capable of managing the output content of various media or substances that are expected to have a repellent effect on birds and animals.

[0039] For example, each entry in the medium management table 242 may include an output unit ID field. The output unit ID field indicates identification information (output unit ID) that can identify one or more first output units 111 that should output the medium, from among a plurality of first output units 111, each located in a different position. This allows the first output unit 111 that should output the medium or substance to be specified as the output content of the medium or substance.

[0040] Figure 5 shows an example of the configuration of a bird / animal-medium management table used in a bird / animal intrusion prevention system according to the first embodiment. The bird / animal-medium management table 243 contains n entries corresponding to n birds (or n heads, n birds). The n birds / animals may be n different species of birds / animals, or n individuals. Each of the n entries contains a bird / animal ID field, an output ID field, and m medium history fields. n is, for example, any integer greater than or equal to 1. m is, for example, any integer greater than or equal to 1.

[0041] In an entry corresponding to a bird or animal, the Bird / Animal ID field indicates unique identification information (Bird / Animal ID) that can identify that bird or animal. Specifically, the Bird / Animal ID field may be set to the Bird / Animal ID assigned to the corresponding bird or animal species (e.g., deer). Alternatively, the Bird / Animal ID field may be set to the Bird / Animal ID assigned to an individual of the corresponding bird or animal (e.g., a specific deer).

[0042] The Output ID field indicates unique identification information (Output ID) that can identify the output content of the medium or substance used for the corresponding bird or animal. As previously mentioned with reference to the medium management table 242 in Figure 4, the Output ID is associated with information that indicates the specific output content of the medium or substance, for example.

[0043] Each of the m medium history fields indicates an output ID (i.e., an output ID previously set in the output ID field) that shows the output content of the medium or substance previously used against the corresponding bird or animal. The m medium history fields include, for example, a first medium history field, a second medium history field, ..., and the mth medium history field. The first medium history field, the second medium history field, ..., and the mth medium history field may have output IDs set in order from the most recent to the most recent, as set in the output ID field. The output content of the medium or substance corresponding to the output ID set in the medium history field is assumed to have been used against the corresponding bird or animal before and to have a low repellent effect. Therefore, the output ID set in the medium history field is not set in the output ID field corresponding to that bird or animal, for example.

[0044] In the example shown in Figure 5, for example, it is specified that the output content of a medium or substance with output ID "152" should be used for a bird or animal with bird / animal ID "001". It is also shown that the output content of a medium or substance with output ID "078" and the output content of a medium or substance with output ID "138" have been used in the past for the bird or animal with bird / animal ID "001".

[0045] For example, for birds and animals with bird / animal ID "002", it is specified that the output content of a medium or substance with output ID "035" should be used. The output content of this medium or substance with output ID "035" is to output light of wavelength W1 in emission pattern B, as defined in the medium management table 222 shown in Figure 4.

[0046] With the configuration of the above-described wildlife-medium management table 243, the wildlife intrusion prevention system 100 can manage the output content of the medium or substance used for each wildlife. Specifically, the wildlife intrusion prevention system 100 can manage, for each wildlife, the output content of the medium or substance that should be used now, and the output content of the medium or substance that has been used in the past and whose repellent effect has decreased.

[0047] Next, we will describe an example of the operation of the wildlife intrusion prevention system configured as described above. Figure 6 is a flowchart showing an example of the operation of the wildlife intrusion prevention system according to the first embodiment. We will describe an example of the operation of the wildlife intrusion prevention system 100 with reference to Figure 6. Furthermore, all of the following operations may be performed in the output control unit 104.

[0048] When the wildlife intrusion prevention system 100 starts operating, it begins monitoring for the intrusion of birds, animals, and other objects to be avoided.

[0049] (Step S100) Set the initial value for the first output, 120.

[0050] (Step S102) The wildlife detection unit 131 determines whether or not it has detected wildlife. If the wildlife detection unit 131 does not detect wildlife in step S102, the process in step S102 is repeated.

[0051] (Step S104) If the animal detection unit 131 detects an animal in step S102, the output control unit 104 determines the first output 120 and outputs the first output 120 from the first output unit 111.

[0052] (Step S106) When the first output 120 is output from the first output unit 111 in step S104, the wildlife detection unit 131 determines whether or not the wildlife has learned (become accustomed to) the first output 120. In this embodiment, learning means that the wildlife becomes accustomed to the first output 120, resulting in a loss of sufficient repellent effect. If the wildlife has learned the first output 120, it is not possible to prevent the wildlife from entering the predetermined area. To determine whether or not the wildlife has learned the first output 120 or the second output 220, data such as the stopping time, number of individuals, frequency, and heart rate of wildlife within a predetermined area in the wildlife damage prevention program of Patent Document 2 can be used. If the wildlife has not learned the first output 120, the process in step S102 is repeated. Also, if the wildlife detection unit 131 does not detect any wildlife, the output of the first output 120 stops.

[0053] (Step S107) If the bird or animal has learned the first output 120 in step S106, the output control unit 104 is notified that the bird or animal has learned the first output 120 (that the bird or animal will continue to be detected in the designated area even if the first output 120 is output). The bird or animal detection unit 131 also notifies the output control unit 104 to stop outputting the first output 120.

[0054] (Step S108) The output control unit 104 stores the contents (instructions) of the first output 120 for the first output unit 111.

[0055] (Step S110) The system determines whether the object detection unit 130 has detected an object to be avoided (i.e., whether an object to be avoided, such as a drone or robot, has been intentionally activated). If the object detection unit 130 does not detect an object to be avoided in step S110, the process in step S110 is repeated.

[0056] (Step S112) If the object to be avoided detection unit 130 detects (activates) an object to be avoided in step S110, the output control unit 104 determines the second output 220 and outputs the second output 220 from the first output unit 111. Here, in steps S104 to S112, the first output 120 and the second output 220 are different.

[0057] (Step S114) When the second output 220 is output from the first output unit 111 in step S112, a determination is made as to whether or not the bird or animal has learned the second output 220 (become accustomed to the second output 220).

[0058] (Step S116) If the bird or animal has learned the second output 220 in step S114, the output control unit 104 stops outputting the second output 220 and stores the content (instruction) of the second output 220 to the first output unit 111. The output control unit 104 also determines a new second output 220 and repeats the process in step S112.

[0059] (Step S118) If the bird or animal has not learned the second output 220 in step S114, a decision is made as to whether or not to terminate the system. If the system is not terminated in step S118, the process in step S102 is repeated. In this case, if the system is not terminated in step S118 and the process in step S102 is repeated, the second output 220 is output as the first output 120.

[0060] In the operation described above, the output of the first output unit 111 makes it possible to reduce the intrusion of birds and animals. This is because, when the medium 120-1 or substance 120-2 of the first output 120 is the same as the medium 120-1 or substance 120-2 of the second output 220, birds and animals with high learning ability are more likely to recognize the association between the second output 220 and the repellent and flee. As a result, the repellent effect of the bird and animal intrusion prevention system on birds and animals can be further enhanced and maintained for a longer period, making it possible to more effectively deter the intrusion of birds and animals into areas such as solar power plants, wind power plants, railway facilities, airports, and farmlands. In addition, when the approach or intrusion of birds and animals is detected, the repellent does not need to go to the site each time to deter intrusion, making it possible to deter the intrusion of birds and animals at a lower cost. As a result, it is possible to prevent damage to the equipment of these facilities by birds and animals and minimize economic losses.

[0061] (Second Embodiment) First observation unit, first output unit, second output unit Figure 7 is a schematic diagram representing the bird and animal intrusion prevention system according to the second embodiment. Figure 8 is a schematic diagram representing the configuration of the bird and animal intrusion prevention system according to the second embodiment. The bird and animal intrusion prevention system 200 includes a first observation unit 101, a first output unit 111, a second output unit 212, a detection unit 103, and an output control unit 104. The detection unit 103 includes a repellent target detection unit 130 and a bird and animal detection unit 131. The second embodiment differs from the first embodiment in that the first output unit 111 is installed near birds and animals, and the second output unit 212 is installed near repellent targets.

[0062] The second output unit 212 is installed near a repellent object that is expected to have a repellent effect on birds and animals. When the repellent object detection unit 130 detects a repellent object, it outputs a medium 120-1 or substance 120-2 that causes a change in the medium or substance of the surrounding environment of a predetermined area as the second output 220, based on the input to the output control unit 104.

[0063] The second output unit 212 outputs a medium 120-1 or a substance 120-2. Examples include speakers that emit sound waves or ultrasound, and lighting that emits light. Multiple units may be installed, and multiple types may be used in combination. For example, workers performing tasks at mega solar power plants, farmlands, railway tracks, etc., may carry smartphones and emit sound from these smartphones during their work to alert birds and animals to the presence of people who are repelled. Alternatively, dogs released into farmland or drones may be equipped with output devices that emit sound waves or light to alert birds and animals to their presence. Furthermore, the second output unit 212 may communicate with the output control unit by wire or wireless connection.

[0064] (Modified version of the second embodiment) First observation unit, first output unit, second output unit, third output unit Figure 9 is a schematic diagram showing the configuration of a modified version of the second embodiment of the animal intrusion prevention system. As shown in Figure 9, the deterrent may include a third output unit 213 in addition to the second output unit 212. The third output unit 213 may, for example, have a drone or robot spray liquid such as water, set off firecrackers, spray smoke, spray bear repellent spray, or emit laser light. The output of the third output unit 213 is controlled by the output control unit 104. Such operations may be performed only when the drone or robot detects an animal. This prevents the deterrent effect from decreasing as the animal learns that it is not in danger and that even drones and robots are safe, even if they repeatedly encounter them.

[0065] In the operation described above, the output of the first output unit 111 makes it possible to reduce the intrusion of birds and animals. This is because, when the medium 120-1 or substance 120-2 of the first output 120 is the same as the medium 120-1 or substance 120-2 of the second output 220, birds and animals with high learning ability are more likely to recognize the association between the second output 220 and the repellent object and flee. In particular, when the repellent object activates the third output unit 213, the repellent effect of the repellent object is further enhanced, which in turn enhances the repellent effect of the output of the second output unit 212, and consequently enhances the repellent effect of the output of the first output unit 111.

[0066] Furthermore, a second observation unit can be installed separately from the first observation unit 101. In this case, the first observation unit 101 may detect birds and animals, while the second observation unit may detect objects to be avoided, with each observation unit detecting a different object. The first observation unit 101, the second observation unit, the first output unit 111, and the second output unit 212 can be combined, and at least the first observation unit 101 and the first output unit 111 are required.

[0067] While several embodiments of the present invention have been described, these embodiments are presented as examples only and are not intended to limit the scope of the invention. These embodiments can be carried out in a variety of other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their variations are included in the scope and spirit of the invention, as well as in the claims and their equivalents. [Explanation of Symbols]
