[0011] Hereinafter, embodiments of the present disclosure will be described.

[0012] (Overview of the embodiment) An overview of a system 1 according to an embodiment of the present disclosure will be described with reference to Fig. 1. The system 1 includes a plurality of terminal devices 10, an unmanned aerial vehicle 20, and an information processing device 30. The information processing device 30 is capable of communicating with each of the terminal devices 10 and the unmanned aerial vehicle 20 via a network 40 including, for example, the Internet and a mobile communication network.

[0013] The terminal device 10 is a computer such as a PC (Personal Computer), a smartphone, or a tablet terminal. In this embodiment, the terminal device 10 is used by a farm manager such as an agricultural worker. Each terminal device 10 can be used by, for example, different farm manager. In one example, each farm manager acquires a user account to be used in the system 1 in advance. The terminal device 10 performs a login process in response to an operation by the farm manager, and then can reserve the spraying of pesticides by the unmanned aerial vehicle 20 on a specified farm.

[0014] The unmanned aerial vehicle 20 is any aircraft that does not have a person on board. For example, an aircraft such as a drone or a multicopter can be used as the unmanned aerial vehicle 20. In this embodiment, the unmanned aerial vehicle 20 is used by, for example, an agent that sprays pesticides on behalf of a manager of a farm field. The unmanned aerial vehicle 20 is equipped with a spraying device that sprays pesticides from the sky to the ground, and can perform pesticide spraying on a farm field from the sky either autonomously or by working with an information processing device 30. For example, the unmanned aerial vehicle 20 can automatically perform pesticide spraying at a specified time on a farm field designated as a spraying target according to an operation plan notified by the information processing device 30. Note that preliminary work for pesticide spraying, such as charging the battery equipped in the unmanned aerial vehicle 20 and refilling the spraying device with pesticides, may be performed by the manager of the farm field or an agent for pesticide spraying.

[0015] The information processing device 30 is a computer such as a PC, a smartphone, a tablet terminal, or a server. The information processing device 30 is capable of communicating with each of the terminal device 10 and the unmanned aerial vehicle 20 via a network 40. In this embodiment, the information processing device 30 is used, for example, by an agent for pesticide spraying. In one example, when the information processing device 30 accepts a reservation for spraying pesticides on a field from a manager of the field, it determines an operation plan for the unmanned aerial vehicle 20 according to the reservation contents, and notifies the unmanned aerial vehicle 20 of the operation plan, thereby causing the unmanned aerial vehicle 20 to spray pesticides on the field.

[0016] First, an overview of this embodiment will be described, and details will be described later. The information processing device 30 acquires information about each of a plurality of fields. Then, the information processing device 30 determines the timing of spraying the pesticide on the first field by the unmanned aerial vehicle 20 based on information about another field (hereinafter also referred to as the "second field") located in the vicinity of the field (hereinafter also referred to as the "first field") to which the pesticide is to be sprayed.

[0017] According to this embodiment, the timing of spraying pesticides on the first field by the unmanned aerial vehicle 20 is determined based on information on the second field. For example, if the timing of spraying pesticides on the first field is determined to be, for example, after the harvest of crops in the second field is completed or after the planned harvest time of crops in the second field, the likelihood of the scattered pesticide adhering to crops in the second field is reduced. Therefore, according to this embodiment, even if the pesticide sprayed on the first field by the unmanned aerial vehicle 20 is scattered to the second field, the probability that the scattered pesticide will adversely affect the crops in the second field can be reduced, improving the technology of spraying pesticides on fields using the unmanned aerial vehicle 20.

[0018] Next, the configuration of the information processing device 30 included in the system 1 will be described in detail.

[0019] (Configuration of information processing device) As shown in FIG. 2, the information processing device 30 includes a communication unit 31, a storage unit 32, and a control unit 33.

[0020] The communication unit 31 includes one or more communication interfaces that connect to the network 40. The communication interface corresponds to a mobile communication standard such as 4G (4th Generation) or 5G (5th Generation), a wired LAN (Local Area Network) standard, or a wireless LAN standard, but is not limited to these and may correspond to any communication standard. In this embodiment, the information processing device 30 communicates with each of the terminal device 10 and the unmanned aerial vehicle 20 via the communication unit 31 and the network 40.

[0021] The storage unit 32 includes one or more memories. The memories are, for example, but not limited to, semiconductor memories, magnetic memories, or optical memories. Each memory included in the storage unit 32 may function as, for example, a main storage device, an auxiliary storage device, or a cache memory. The storage unit 32 stores any information used in the operation of the information processing device 30. For example, the storage unit 32 may store a system program, an application program, embedded software, a database, and the like.

[0022] The control unit 33 includes one or more processors, one or more programmable circuits, one or more dedicated circuits, or a combination of these. The processor is, for example, but is not limited to, a general-purpose processor such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit), or a dedicated processor specialized for a specific process. The programmable circuit is, for example, but is not limited to, an FPGA (Field-Programmable Gate Array). The dedicated circuit is, for example, but is not limited to, an ASIC (Application Specific Integrated Circuit). The control unit 33 controls the operation of the entire information processing device 30.

[0023] (Operation flow of information processing device) The operation of information processing device 30 will be described with reference to Fig. 3. In summary, this operation is an operation for determining an operation plan for unmanned aerial vehicle 20 that will spray pesticides in response to a reservation from the manager of the farm field.

[0024] Step S100: The control unit 33 of the information processing device 30 acquires information about each of the multiple farm fields.

[0025] Specifically, the manager of each field inputs information about the field to the terminal device 10. The control unit 33 of the information processing device 30 receives the information about each field from each terminal device 10 via the communication unit 31, and stores the information in the storage unit 32. However, the method for acquiring the information about the field is not limited to this example, and any method can be adopted.

[0026] Here, "information relating to the field" may include, for example, information indicating the user account of the field manager, identification information of the field, the location of the field, whether harvesting of crops in the field has been completed, the planned harvest time, and the crops in the field, but is not limited to these and may include any information related to the field. Note that information indicating "whether harvesting has been completed" may be, for example, but is not limited to, a flag indicating whether harvesting has been completed or not, or information indicating the date and time of harvest completion. Furthermore, "time" may mean a "period" that has a temporal length, or may mean a "point in time" that does not have a temporal length.

[0027] Step S101: Control unit 33 acquires reservation information for unmanned aerial vehicle 20 spraying pesticides on a first field.

[0028] Specifically, a manager of a certain field (first field) inputs reservation information for spraying pesticides on the first field by an unmanned aerial vehicle 20 into the terminal device 10. The terminal device 10 transmits the input reservation information to the information processing device 30. The control unit 33 of the information processing device 30 receives the reservation information from the terminal device 10 via the communication unit 31 and stores it in the memory unit 32. However, the method for acquiring the reservation information is not limited to this example, and any method can be adopted.

[0029] Here, the "reservation information" may include, for example, information indicating the planned time for pesticide spraying, the pesticide to be used, and the standards for using the pesticide, but is not limited to these and may include any information necessary for reserving pesticide spraying in the first field by unmanned aerial vehicle 20. For example, the reservation information may further include information specifying the area in the first field to which the pesticide is to be sprayed. Here, the "standards for using pesticides" include, for example, crops for which pesticides can be used (i.e., crops suitable for using pesticides) and the time (for example, more than 24 hours before harvesting), but are not limited to these. The standards for using pesticides may be determined, for example, by law.

[0030] Step S102: The control unit 33 identifies a second field located in the vicinity of the first field.

[0031] Specifically, the control unit 33 extracts the position of each field from the information about each field stored in the memory unit 32 in step S100, and identifies, for example, another field located within a predetermined distance from the first field as the second field.

[0032] Step S103: Control unit 33 executes a decision process to decide the timing for unmanned aerial vehicle 20 to spray pesticides on the first field, based on the information related to the second field.

[0033] Execution of the determination process determines the timing of pesticide spraying on the first field by unmanned aerial vehicle 20. A specific example of the determination process will be described later, but in summary, even if the pesticide sprayed by unmanned aerial vehicle 20 is blown into the second field, an appropriate execution time is determined so that adverse effects of the blown pesticide on crops in the second field are reduced. For this reason, the execution time determined by the determination process does not necessarily match the planned execution time indicated in the reservation information in step S101.

[0034] Step S104: The control unit 33 determines an operation plan for the unmanned aerial vehicle 20 based on the reservation information in step S101 and the implementation time determined in step S103, and notifies the unmanned aerial vehicle 20.

[0035] Specifically, control unit 33 determines an operation plan for unmanned aerial vehicle 20 so as to spray the pesticide indicated in the reservation information onto the first field at the implementation time determined in step S103, and notifies unmanned aerial vehicle 20 via communication unit 31. Unmanned aerial vehicle 20 then automatically sprays the pesticide onto the first field in accordance with the notified operation plan.

[0036] (First example of decision processing) A first example of the determination process in step S103 described above will be described with reference to Fig. 4. In the first example, the timing of pesticide spraying in the first field is determined to be after the harvest of crops in the second field is completed. In the first example, it is assumed that the reservation information includes information indicating the planned timing of pesticide spraying. Furthermore, the information on each field includes information indicating whether the harvest of crops in the field has been completed.

[0037] Step S200: Control unit 33 identifies the planned time for unmanned aerial vehicle 20 to spray pesticides on the first field, based on the reservation information in step S101 described above.

[0038] Step S201: The control unit 33 determines, from the information about the second field stored in the storage unit 32, whether or not the harvest of crops in the second field has been completed.

[0039] Step S202: The control unit 33 determines whether or not the harvest of the crops in the second field is complete. If it is determined that the harvest is complete (step S202-Yes), the process proceeds to step S203. On the other hand, if it is determined that the harvest is not complete (step S202-No), the process proceeds to step S204.

[0040] Specifically, the control unit 33 determines that the harvest of crops in the second field is complete if the information about the second field includes information indicating that the harvest is complete. On the other hand, the control unit 33 determines that the harvest of crops in the second field is not complete if the information about the second field does not include information indicating that the harvest is complete or if the information about the second field includes information indicating that the harvest is not complete.

[0041] Step S203: If it is determined in step S202 that the harvest is complete (step S202-Yes), control unit 33 determines the planned implementation time as the implementation time for spraying pesticides on the first field by unmanned aerial vehicle 20. Thereafter, the process proceeds to step S104 described above.

[0042] As will be described later, the operation of step S203 may be executed after the scheduled implementation time is postponed in step S207. For this reason, the "scheduled implementation time" in step S203 does not necessarily match the scheduled implementation time indicated in the reservation information in step S101.

[0043] Step S204: If it is determined in step S202 that the harvest is not completed (step S202-No), the control unit 33 sends a message to the manager of the second field requesting him to complete the harvest of the crops in the second field before the scheduled time.

[0044] Specifically, the control unit 33 identifies the user account of the manager of the second field from the information about the second field, and transmits the message to the user account. The manager of the second field can check the message using the terminal device 10.

[0045] Step S205: The control unit 33 determines whether the manager of the second field complies with the request in the message of step S204 (i.e., whether the manager of the second field completes harvesting the crops in the second field before the scheduled time). If it is determined that the manager of the second field complies with the request (step S205-Yes), the process proceeds to step S206. On the other hand, if it is determined that the manager of the second field does not comply with the request (step S205-No), the process proceeds to step S207.

[0046] Specifically, the manager of the second field checks the message in step S204. If the manager of the second field complies with the request in the message, the manager completes the harvest of the crops in the second field before the scheduled time, and inputs information indicating that the harvest has been completed into the terminal device 10. The terminal device 10 returns the input information to the information processing device 30. When the control unit 33 of the information processing device 30 receives the information from the terminal device 10 via the communication unit 31, it determines that the manager of the second field has complied with the request. The control unit 33 also updates the information related to the second field stored in the memory unit 32 to indicate that the harvest has been completed.

[0047] On the other hand, if the manager of the second field does not comply with the request in the message, he / she inputs information indicating that he / she does not comply with the request into the terminal device 10. Here, the manager of the second field may further input the planned harvest time of the crop in the second field into the terminal device 10. The terminal device 10 returns the input information to the information processing device 30. When the control unit 33 of the information processing device 30 receives the information from the terminal device 10 via the communication unit 31, it determines that the manager of the second field did not comply with the request.

[0048] If there is no reply from the terminal device 10 of the manager of the second field by a predetermined deadline before the scheduled implementation time, the control unit 33 may determine that the manager of the second field did not respond to the request.

[0049] Step S206: If it is determined in step S205 that the manager of the second field complies with the message request (step S205-Yes), the control unit 33 grants a reward to the manager of the second field. After that, the process proceeds to step S203.

[0050] Specifically, the control unit 33 gives a reward to the user account of the manager of the second field. Here, the "reward" is, for example, data such as electronic money, cryptocurrency, or an electronic coupon, but is not limited to these.

[0051] Note that the operations of steps S204-S206 may be performed after the scheduled implementation time is postponed in step S207, as described later. For this reason, the "scheduled implementation time" of steps S204-S206 does not necessarily match the scheduled implementation time indicated in the reservation information in step S101. That is, if the scheduled implementation time indicated in the reservation information in step S101 is T1, and the scheduled implementation time when it is determined in step S205 that the manager of the second field has responded to the message request is T2, T2 may be later than T1. Therefore, when the control unit 33 awards a reward to the manager of the second field in step S206, for example, when T1 and T2 are the same, the award may be increased compared to when T2 is later than T1. Alternatively, the control unit 33 may award a smaller reward the greater the difference between T1 and T2. In either case, the manager of the second field can receive the maximum reward by completing the harvest of the crops in the second field by T1, which is the planned implementation time shown in the reservation information (i.e., the planned implementation time of the pesticide spraying desired by the manager of the first field). This increases the probability that the harvest of the crops in the second field will be completed by T1.

[0052] Step S207: If it is determined in step S205 that the manager of the second field has not responded to the message request (step S205-No), the control unit 33 postpones the scheduled implementation time. After that, the process returns to step S204.

[0053] In this way, according to the determination process of the first example, the timing of pesticide spraying on the first field is determined after it is determined in step S202 or step S205 that the harvest of crops in the second field is completed. That is, the timing of pesticide spraying on the first field is determined to be after the harvest of crops in the second field is completed. Therefore, even if the pesticide sprayed on the first field by the unmanned aerial vehicle 20 is scattered to the second field, the likelihood that the scattered pesticide will adhere to the crops in the second field is reduced.

[0054] (Second example of decision processing) A second example of the determination process in step S103 described above will be described with reference to Fig. 5. As a premise, in the second example, unlike the first example described above, the reservation information does not need to include information indicating the planned time for carrying out pesticide spraying. Also, the information on each farm field includes information indicating the planned time for harvesting crops in the farm field.

[0055] Step S300: The control unit 33 identifies a planned harvest time of the crop in the second field from the information about the second field stored in the memory unit 32.

[0056] Step S301: Control unit 33 determines the timing for spraying pesticides on the first field by unmanned aerial vehicle 20 to be after the planned harvest time identified in step S300. The process then proceeds to step S104 described above.

[0057] In this way, according to the determination process of the second example, the timing of pesticide spraying in the first field is determined to be later than the planned harvest time of the crops in the second field. Therefore, since there is a high probability that the harvest of the crops in the second field will be completed before the pesticide spraying in the first field is performed, even if the pesticide sprayed in the first field by the unmanned aerial vehicle 20 is scattered to the second field, the probability that the scattered pesticide will directly come into contact with the crops in the second field is reduced.

[0058] (Third example of decision processing) A third example of the decision process in step S103 described above will be described with reference to Fig. 6. In the third example, the timing of pesticide spraying by unmanned aerial vehicle 20 on the first field varies depending on whether the second field satisfies the use standard of the pesticide to be sprayed on the first field. In the third example, the reservation information includes information indicating the pesticide to be sprayed on the first field and / or the use standard of the pesticide. The information on each field includes information indicating the crop and / or the planned harvest time in the second field.

[0059] Step S400: The control unit 33 identifies the crop and / or the planned harvest time in the second field from the information about the second field stored in the memory unit 32.

[0060] Step S401: The control unit 33 identifies the usage standard of the pesticide to be sprayed in the first field from the reservation information in the above-mentioned step S101.

[0061] Specifically, when the reservation information includes information indicating the use standards of the pesticide, the control unit 33 identifies the use standards of the pesticide from the reservation information. Alternatively, when the reservation information does not include information indicating the use standards of the pesticide, the control unit 33 identifies the pesticide from the reservation information and identifies the use standards of the pesticide by acquiring the use standards of the pesticide from an external server on the network 40 via the communication unit 31. As described above, the use standards of the pesticide are, for example, the crops and the time when the pesticide can be used.

[0062] Step S402: The control unit 33 determines whether the second field meets the pesticide use standard based on the information about the second field. If it is determined that the second field meets the pesticide use standard (step S402-Yes), the process proceeds to step S403. On the other hand, if it is determined that the second field does not meet the pesticide use standard (step S402-No), the process proceeds to step S404.

[0063] Specifically, the control unit 33 may determine that the second field does not meet the pesticide use standards when the crops in the second field are not crops for which pesticides can be used. The control unit 33 may also determine that the second field does not meet the pesticide use standards when the planned time for spraying the pesticide on the first field does not fall within the time when the pesticide can be used on the crops in the second field. On the other hand, the control unit 33 may determine that the second field meets the pesticide use standards when the crops in the second field are crops for which pesticides can be used and the planned time for spraying the pesticide on the first field falls within the time when the pesticide can be used on the crops in the second field.

[0064] Depending on the pesticide, the use standard may specify only the crops and the period when the pesticide can be used. In such a case, the control unit 33 may determine that the second field satisfies the use standard for the pesticide if the crops in the second field correspond to the crops for which the pesticide can be used, or if the planned period for spraying the pesticide in the first field corresponds to the period when the pesticide can be used for the crops in the second field.

[0065] Step S403: If it is determined in step S402 that the second field satisfies the pesticide use standard (step S402-Yes), control unit 33 determines the planned implementation time as the implementation time for spraying the pesticide on the first field by unmanned aerial vehicle 20. After that, the process proceeds to step S104 described above.

[0066] Step S404: If it is determined in step S402 that the second field does not meet the pesticide use standard (step S402-No), control unit 33 determines the timing of pesticide spraying by unmanned aerial vehicle 20 to be after the planned harvest time identified in step S400. The process then proceeds to step S104 described above.

[0067] In this way, according to the determination process of the third example, if it is determined that the second field meets the pesticide use standards, the planned implementation time indicated in the reservation information is determined as the implementation time for the pesticide spraying in the first field. Since the second field meets the pesticide use standards, even if the pesticide sprayed in the first field by the unmanned aerial vehicle 20 before the harvest of the crops in the second field is scattered to the second field, the probability that the pesticide will have an adverse effect on the crops in the second field is low.

[0068] On the other hand, if it is determined that the second field does not meet the standards for the use of pesticides, the timing of the pesticide spraying in the first field is determined to be after the planned harvest time of the crops in the second field. Therefore, since there is a high probability that the harvest of the crops in the second field will be completed before the pesticide spraying in the first field is implemented, even if the pesticide sprayed in the first field by the unmanned aerial vehicle 20 is scattered to the second field, the probability that the scattered pesticide will adhere to the crops in the second field is reduced.

[0069] As described above, the information processing device 30 according to this embodiment acquires information about each of the multiple fields. Then, the information processing device 30 determines the timing of spraying the pesticide on the first field by the unmanned aerial vehicle 20 based on information about the second field located in the vicinity of the first field to be sprayed with the pesticide.

[0070] According to this configuration, the timing of the pesticide spraying to the first field by the unmanned aerial vehicle 20 is determined based on information about the second field. For example, if the timing of the pesticide spraying to the first field is determined to be, for example, after the harvest of the crops in the second field is completed or after the planned harvest time of the crops in the second field, the likelihood of the scattered pesticide adhering to the crops in the second field is reduced. Therefore, according to this embodiment, even if the pesticide sprayed to the first field by the unmanned aerial vehicle 20 is scattered to the second field, the probability that the scattered pesticide will adversely affect the crops in the second field can be reduced, thereby improving the technology of spraying pesticide to a field using the unmanned aerial vehicle 20.

[0071] Although the present disclosure has been described based on the drawings and examples, it should be noted that those skilled in the art may make various modifications and alterations based on the present disclosure. Therefore, it should be noted that these modifications and alterations are included in the scope of the present disclosure. For example, the functions included in each component or step can be rearranged so as not to be logically inconsistent, and multiple components or steps can be combined or divided into one.

[0072] For example, in the above-described embodiment, the configuration and operation of the information processing device 30 may be distributed among a plurality of computers capable of communicating with each other.

[0073] Also, for example, an embodiment is possible in which a general-purpose computer functions as the information processing device 30 according to the above-described embodiment. Specifically, a program describing the processing contents for realizing each function of the information processing device 30 according to the above-described embodiment is stored in the memory of the general-purpose computer, and the program is read and executed by a processor. Therefore, the present disclosure can also be realized as a program executable by a processor, or a non-transitory computer-readable medium that stores the program.

[0074] In the above-described embodiment, the operation of the information processing device 30 that executes the decision process has been specifically described with reference to Examples 1 to 3. However, the information processing device 30 that executes the decision process may execute an appropriate combination of the operations described in Examples 1 to 3.

[0075] For example, if the control unit 33 of the information processing device 30 determines that crop harvesting in the second field has been completed (similar to step S202-Yes in the first example), or if the second field is determined to meet the pesticide use standards (similar to S402-Yes in the third example), it may determine that the planned implementation time indicated in the reservation information is the time to spray the pesticide on the first field (similar to step S203 in the first example or step S403 in the third example). On the other hand, if the control unit 33 determines that the harvest of crops in the second field has not been completed (similar to step S202-No in the first example) and that the second field does not meet the pesticide use standards (similar to S402-No in the third example), it may decide that the unmanned aerial vehicle 20 will spray pesticide on the first field later than the planned harvest time of the second field (similar to step S301 in the second example or step S404 in the third example).

[0076] Some of the embodiments of the present disclosure will be described below as examples. However, it should be noted that the embodiments of the present disclosure are not limited to these examples.
