Description

[Technical field]

[0001] The present invention relates to a drug dispersion plan creation support device and method. [Background technology]

[0002] A technology that supports pest control based on the period when pesticide use is prohibited and the planned harvest period of crops is known (Patent Document 1). A technology for spraying pesticides and other chemicals using drones has also been proposed (Patent Document 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2023-84773 A [Patent Document 2] JP 2018-111429 A Summary of the Invention [Problem to be solved by the invention]

[0004] In Patent Document 1, the planned harvest time and the agricultural chemical spraying time are simply matched, and other conditions that should be considered when spraying pesticides, particularly conditions related to the scattering of pesticides, are not taken into consideration at all. Patent Document 2 also does not consider conditions related to the scattering of pesticides at all. However, in reality, the range of scattering of pesticides varies depending on the time of day, wind direction, buildings near the field, and the type of pesticide sprayer used for spraying pesticides. Therefore, it is not appropriate to make a pesticide spraying plan without considering conditions related to the scattering of pesticides.

[0005] Therefore, an object of the present disclosure is to provide a drug dispersion plan creation support device and method that can assist in the creation of an appropriate drug dispersion plan and is easy for users to use. [Means for solving the problem]

[0006] In order to solve the above problems, a pesticide spraying plan creation support device according to one aspect of the present invention is a pesticide spraying plan creation support device that supports the creation of a pesticide spraying plan for spraying pesticide to a field, acquires pesticide information and information on a target field to which the pesticide is to be sprayed, calculates spraying time information including a candidate date and time for spraying the pesticide to the target field based on the acquired target field information, the pesticide information, and predetermined spraying conditions including at least conditions related to pesticide dispersion, transmits the calculated spraying time information to a user terminal, and stores the candidate date and time selected by the user terminal based on the spraying time information in a memory unit as a pesticide spraying plan. Effect of the Invention

[0007] According to the present invention, it is possible to assist in creating a pesticide spray plan that takes into account conditions related to pesticide dispersion. [Brief description of the drawings]

[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The pesticide spraying plan creation support device according to the present disclosure supports efficient creation of plans that thoroughly consider all conditions that should be considered when spraying pesticides in a field. The pesticide spraying plan creation support device creates pesticide spraying plan candidates, provides them to a user terminal, registers pesticide spraying plans approved by the user terminal, and saves the results of their execution. EXAMPLES

[0010] The first embodiment will be described with reference to Figures 1 to 12. Figure 1 is a configuration diagram of a drug dispersion plan creation support system 1 including a drug dispersion plan creation support device 2.

[0011] The pesticide spraying plan creation support system 1 may include, for example, a pesticide spraying plan creation support device 2, an agricultural cooperative terminal 3, a farmer terminal 4, and an external database 5. Each of these devices 2, 3, 4, and 5 is communicatively connected via a communication network CN such as the Internet. The devices 3, 4, and 5 will be described first, and then the pesticide spraying plan creation support device 2 will be described last.

[0012] The agricultural cooperative terminal 3 and the farmer terminal 4 correspond to "user terminals." The agricultural cooperative terminal 3 corresponds to the "first user terminal" used by an agricultural cooperative employee as the "first user." The farmer terminal 4 corresponds to the "second user terminal" used by a farmer as the "second user." The farmer terminal 4 is not necessarily required, and an agricultural cooperative employee may act as an intermediary for the exchange of information between the farmer and the pesticide spraying plan creation support device 2. In the following explanation, the agricultural cooperative terminal 3 and / or the farmer terminal 4 may be referred to as user terminals 3, 4. The agricultural cooperative employee and the farmer may be referred to as users.

[0013] The external database 5 manages, for example, weather information, map information, drug information, etc. The drug dispersion plan creation support device 2 can also acquire weather information, map information, drug information, etc. from the external database 5 to the extent necessary, and store them in the database unit 250 within the drug dispersion plan creation support device 2.

[0014] The drug dispersion plan creation support device 2 is configured as a computer having, for example, a memory unit 21, a calculation unit 22, a communication unit 23, and a user interface unit 24. In the figure, the user interface is abbreviated as "UI." The drug dispersion plan creation support device 2 creates candidates for drug dispersion plans PA and proposes them to user terminals 3 and 4, and registers the drug dispersion plan candidates approved by the user terminals 3 and 4 as drug dispersion plans PA.

[0015] The storage unit 21 includes a main storage device and an auxiliary storage device. The storage unit 21 stores, for example, a chemical spraying time proposing unit 210, a target field determining unit 220, a chemical use determining unit 230, a screen generating unit 240, and a database unit 250.

[0016] The pesticide spraying timing suggestion unit 210 has the function of calculating the time to spray the pesticide (candidate dates and times for pesticide spraying) and providing this to the agricultural cooperative terminal 3, which is a user terminal. The candidate dates and times for pesticide spraying may be sent only from the pesticide spraying plan creation support device 2 to the agricultural cooperative terminal 3, or may also be sent from the agricultural cooperative terminal 3 to the farmer terminal 4. The candidate dates and times for pesticide spraying may be sent from the pesticide spraying plan creation support device 2 to both the agricultural cooperative terminal 3 and the farmer terminal 4. The same applies when other information is sent from the pesticide spraying plan creation support device 2 to the user terminals 3 and 4.

[0017] The pesticide spraying time proposing unit 210 includes, for example, a work amount quantifying unit 2101, a weather determining unit 2102, a time period determining unit 2103, a drift effect determining unit 2104, a harvest time determining unit 2105, a contamination determining unit 2106, and a pesticide sprayer information determining unit 2107. Each of these units 2101 to 2107 will be described later.

[0018] The target field determination unit 220 has a function of determining the field to be sprayed with the agrochemical. The target field determination unit 220 creates candidate fields based on past performance, transmits the created candidate fields to the user terminals 3 and 4, and determines the field that has been corrected or approved by the user terminals 3 and 4 as the target field. Instead of calculating the candidate fields in the target field determination unit 220, the user terminals 3 and 4 may specify the target field and notify the target field determination unit 220.

[0019] The drug to be used determination unit 230 has a function of determining a drug to be used in the target field. The drug to be used determination unit 230 selects a drug candidate based on the drug database 253 described later, transmits the drug candidate to the user terminal 3, 4, and determines the drug to be used as the drug that has been modified or approved by the user terminal 3, 4. Instead of calculating the drug candidate in the drug to be used determination unit 230, the drug may be specified in the user terminal 3, 4 and notified to the drug to be used determination unit 230.

[0020] The screen generation unit 240 has a function of generating screens used to create a pesticide spray plan and providing them to the user terminals 3 and 4. Users such as agricultural cooperative staff and farmers create pesticide spray plans that satisfy various conditions by exchanging information with the pesticide spray plan creation support device 2 via each screen displayed on the user terminals 3 and 4. The screens G1, G2, and G3 created by the screen generation unit 240 will be described later.

[0021] The database unit 250 stores a database used to create a pesticide spraying plan. The database unit 250 stores not only the results of past pesticide spraying plans (performance data), but also data for the current spraying plan (plan data). The database unit 250 stores, for example, a work performance database 251 described later in FIG. 3, a crop information database 252 described later in FIG. 4, a pesticide database 253, and a spraying caution area database 254 described later in FIG. 6.

[0022] The calculation unit 22 executes the computer programs 210 to 240 stored in the storage unit 21 to realize the functions of the drug dispersion plan creation support device 2. The calculation unit 22 is not limited to a CPU (Central Processing Unit) and may include a GPU (Graphics Processing Unit) or an ASIC (Application Specific Integrated Circuit), etc.

[0023] The drug dispersion plan creation support device 2 can be connected to a storage medium MM. The storage medium MM is configured, for example, as a memory device, a hard disk device, an optical disk device, an optical magnetic disk device, a magnetic tape device, etc., and non-temporarily stores computer programs and data. The storage medium MM can transfer computer programs and data to the storage unit 21 and store them. Computer programs and data can also be transferred from the storage unit 21 to the storage medium MM and stored therein. A computer program that realizes the functions of the drug dispersion plan creation support device 2 is stored in the storage medium MM, the storage medium MM is connected to another computer, and the computer program stored in the storage medium MM is installed in the other computer, so that the other computer can function as the drug dispersion plan creation support device 2.

[0024] Figure 2 is an explanatory diagram showing the relationship between farm fields and the pesticides to be sprayed. Figure 2 is a fictitious schematic map for explanatory purposes. The area shown in Figure 2 includes farm fields F1 and F2, as well as facilities such as parks, schools, and hospitals. In this example, field F1 is the target field to which the pesticides will be sprayed.

[0025] A caution spraying range, shown by a dotted line in the figure, is set so that the pesticide sprayed in the target field F1 does not affect other facilities or other fields. A range within a specified radius from the center of the facility or other field to be warned about is set as the caution spraying range. The range over which the sprayed pesticide spreads varies depending on the weather on the day, particularly the wind speed and direction. Furthermore, the range over which the pesticide spreads outside the target field also varies depending on the particle size of the pesticide. The pesticide spraying plan creation support device 2 calculates candidate pesticide spraying plans taking into account the effects of drift.

[0026] 3 is an example of a database for managing work records (pesticide spraying plans). The work record database 251 manages, for example, a field ID 2510, an owner 2511, an area 2512, a pesticide ID 2513, work date and time 2514, a work environment 2515, and other information 2516. The work record database 251 has a similar configuration to the pesticide spraying plan. Pesticide spraying plans that have been created and executed in the past are stored as the work record database 251.

[0027] The field ID 2510 is identification information that uniquely identifies each field managed by the pesticide spraying plan creation support device 2. The owner 2511 is information that identifies the owner (farmer) of the field identified by the field ID 2510. The area 2512 is the area of ​​the field. The pesticide ID 2513 is identification information that identifies the pesticide used in the field. The work date and time 2514 indicates the date and time when the pesticide spraying work was performed and the period. The work environment 2515 is the environment in which the pesticide spraying work was performed, such as the weather, wind speed, wind direction, and type of pesticide sprayer. For example, a small unmanned aerial vehicle, a so-called drone, is used as the pesticide sprayer. If possible, a sprayer other than a drone may be used. Other information, such as remarks, is stored in the other 2516.

[0028] The configuration of the work record database 251 is not limited to that shown in Fig. 3. Other items may be added, or the names of the items may be different. The work record database 251 may be configured by linking multiple databases. This also applies to other databases described later.

[0029] 4 is an example of a database for managing crop information. The crop information database 252 manages, for example, a field ID 2520, a crop variety 2521, a cropping date 2522, a cropping method 2523, a planned harvest time 2524, and other information 2525.

[0030] The field ID 2520 is the same as the field ID 2510 described above. The crop variety 2521 is information for identifying the type of crop being cultivated in the field. The planting date 2522 indicates the date, time and period when the crop was planted. The planting method 2523 indicates the method of planting the crop. The planned harvest time 2524 indicates the time when the crop is planned to be harvested. Other information such as remarks can be stored in the other 2525.

[0031] 5 is an example of a database for managing a chemical to be sprayed in a farm field. The chemical database 253 stores, for example, a chemical ID 2530, a chemical name 2531, a method of use 2532, a particle size 2533, permitted days after spraying 2534, a prohibited range after spraying 2535, and other information 2536.

[0032] The agent ID 2530 is the same as the agent ID 2513 described in FIG. 3. The agent name 2531 is the name of the agent. The type of agent can be identified from the name of the agent. Here, the agent is, for example, a pesticide. Pesticides include, for example, herbicides, insecticides, fungicides, rodenticides, repellents, miticides, and attractants. The usage method 2532 indicates the method of using the agent (spraying method). The particle size 2533 is the particle size of the agent. The possible number of days after spraying 2534 indicates the number of days that should elapse after the agent is sprayed. Continuous spraying of the agent is prohibited. The prohibited range after spraying 2535 indicates the range in which entry is prohibited after the agent is sprayed.

[0033] 6 is an example of a database for managing areas requiring caution when spraying a chemical. The spraying caution area database 254 manages, for example, a facility ID 2540, a facility name 2541, a spraying caution range 2542, a spraying caution time 2543, and other fields 2544.

[0034] The facility ID 2540 is information that uniquely identifies a facility. The facility name 2541 is the name of the facility. The spraying caution range 2542 is a range within a predetermined radius from the center of the facility within which care must be taken to prevent the pesticide from entering. The spraying caution time 2543 is a time period during which care must be taken to prevent the pesticide from entering the spraying caution range 2542. For example, during normal business hours of the facility, care must be taken to prevent the sprayed pesticide from entering.

[0035] The process of supporting the creation of a plan for spraying a drug by the drug spraying plan creation support system 1 will be described with reference to the flowchart of FIG.

[0036] The pesticide spraying plan creation support device 2 acquires data from the work record database 251 from the database unit 250 (S10), and detects the field and pesticide candidates that are the subject of the current pesticide spraying plan (S11). The pesticide spraying plan creation support device 2 generates a first screen G1 that includes the subject field and pesticide candidates, and transmits it to the agricultural cooperative terminal 3 (S12).

[0037] The first screen G1 is transmitted from the agricultural cooperative terminal 3 to the farmer terminal 4. The first screen G1 can be checked and appropriately edited (modified) on the agricultural cooperative terminal 3 or the farmer terminal 4 (user terminal 3, 4). The edited result is transmitted from the user terminal 3, 4 to the drug spraying plan creation support device 2 and stored in the database unit 250 of the drug spraying plan creation support device 2.

[0038] The target field and the pesticide to be used may be specified by the agricultural cooperative terminal 3 or the farmer terminal 4 and transmitted to the pesticide spraying plan creation support device 2. For example, an agricultural cooperative employee may join a gathering of farmers who own each field, determine the target field and the pesticide, and notify the pesticide spraying plan creation support device 2 via the agricultural cooperative terminal 3. Alternatively, each farmer may gather at the agricultural cooperative to determine the target field and the pesticide, and the results may be transmitted from the agricultural cooperative terminal 3 to the pesticide spraying plan creation support device 2. As described in steps S10 to S12, the pesticide spraying plan creation support device 2 may detect candidates for the target field and candidates for the pesticide, and notify the user terminals 3 and 4.

[0039] When the target field and the drug are determined, the drug spraying plan creation support device 2 calculates candidate dates and times for spraying the drug based on predetermined conditions described later in Fig. 8 (S14). The drug spraying plan creation support device 2 generates a second screen G2 including the calculated candidate dates and times for spraying the drug, and transmits it to the agricultural cooperative terminal 3 (S15).

[0040] The agricultural cooperative staff may transfer the second screen from the agricultural cooperative terminal 3 to the farmer terminal 4 (S16). When each farmer who owns the target field views the second screen G2, he or she can request details of the candidate pesticide spray plan from the pesticide spray plan creation support device 2. The pesticide spray plan creation support device 2 generates a third screen G3 showing details of the candidate pesticide spray plan and sends it to the agricultural cooperative terminal 3 (and / or farmer terminal 4) (S17). The third screen G3 showing the detailed information is sent to the user terminal that requested screen G3.

[0041] Each farmer (or agricultural cooperative staff; the same applies below) can confirm the detailed information displayed on the third screen G3 and approve the candidate pesticide spraying plan. Each farmer can also request corrections to the candidate pesticide spraying plan before approving it.

[0042] When approval is obtained from each farmer, the pesticide spraying plan creation support device 2 registers the pesticide spraying plan candidate in the database unit 250 as a pesticide spraying plan (S18).

[0043] Fig. 8 is a flow chart showing details of step S14 in Fig. 7. The process of calculating candidate dates and times for spraying a drug (step S14) calculates candidate drug spraying schedules taking into consideration predetermined conditions S140 to S146.

[0044] The drug dispersion plan creation support device 2 calculates the following seasonal parameters for a certain period in the future (for example, one month). Furthermore, since weather information and the like may be updated daily, the calculation results are updated daily.

[0045] (D1) Recommended spraying date: The recommended spraying date D1 is a day when the conditions, such as weather, are suitable for spraying pesticides and there are no items requiring special attention.

[0046] (D2) Spray warning day: Spray warning day D2 is a day when spraying pesticides should be done with caution, for example, when the weather is bad or there is a high possibility that the pesticide will drift and affect the surrounding area.

[0047] (D3) Spraying prohibition day: Spraying prohibition day D3 is a day on which spraying of pesticides is not possible, for example, because a pesticide sprayer is not available.

[0048] (D4) Harvestable date: The harvestable date D4 is the date on which the crop can be harvested from the field.

[0049] (D5) Harvesting prohibition day: Harvesting prohibition day D5 is a day on which crops cannot be harvested from a field, for example, because it would be against the law.

[0050] The drug dispersion plan creation support device 2 calculates the above-mentioned work days D1 to D5 by performing calculations for the predetermined conditions S140 to S146. Hereinafter, the relationship between the function blocks 2101 to 2107 shown in Fig. 1 and the processes S140 to S146 shown in Fig. 8 will be described.

[0051] (1) Quantification of workload (S140) The workload quantifying unit 2101, which quantifies the workload, assumes that one day's work hours is eight hours and calculates the workload required for spraying pesticides. The workload quantifying unit 2101 quantifies the workload based on, for example, data from the work record database 251, information on the current target field (e.g., area, etc.), and information on the pesticide sprayer to be used for spraying pesticides (e.g., operating time of the pesticide sprayer, available area for spraying, etc.).

[0052] (2) Determining weather information (S141) The weather determination unit 2102 maps the weather forecast for the calculation date (scheduled spraying date) on a map that includes the target field, and determines the following: (2a) If the weather on the scheduled spraying date or the weather on the day after the scheduled spraying date are both sunny or cloudy, the scheduled spraying date is a candidate for the recommended spraying date. (2b) If either the weather on the scheduled spraying date or the weather on the day after the scheduled spraying date is rainy or snowy, the scheduled spraying date is a candidate for the spraying warning date.

[0053] If it rains or snows on the day of or the day after the planned spraying date, the pesticide may be washed away and its effectiveness may be reduced. However, if there is prolonged rain, it may be possible to spray the pesticide after the rain has stopped.

[0054] (3) Determining spraying time period information (S142) The time zone determination unit 2103 determines the following based on the work time zone on the scheduled spraying date. (3a) If the spraying time zone is in the morning or evening, the scheduled spraying date is a candidate for the recommended spraying date. (3b) If the spraying time zone is during the day, the scheduled spraying date is a candidate for the spraying warning date. This is because rising air currents occur during times of high temperature, which can cause the pesticide to drift. In addition, in the summer, this also serves to prevent heatstroke. (3c) If the spraying time zone is during commuting time, the scheduled spraying date is a candidate for the spraying warning date. In this case, a message is displayed on the screen informing commuters or students that they need to be careful of pesticide drift.

[0055] (4) Determining drift effect information (S143) The drift influence determination unit 2104 maps the target field and the spraying caution zone (no-spraying fields (such as organic farming fields) located near the target field and spraying caution ranges (within a specified radius of the facility) centered on the facility) set for each facility (school, park, hospital, etc.). The lift influence determination unit 2104 makes the following determinations depending on the wind speed on the planned spraying day. (4a) If the wind speed on the planned spraying day is below a threshold, the planned spraying day is set as a candidate for the recommended spraying day. (4b) If the wind speed on the planned spraying day is above a threshold, the planned spraying day is set as a candidate for the spraying warning day. For the spraying warning day, a warning message is output to the screen to the effect that all possible measures to prevent spraying must be taken, such as using a spraying nozzle that is less likely to spray or changing to a pesticide that is less likely to spray (pesticide with a large particle size).

[0056] Furthermore, if there is a spraying caution zone near the target field, the drift influence determination unit 2104 makes the following determination: (4c) If the target field is in the spraying caution zone, and the wind direction on the scheduled spraying date is toward the spraying caution zone and is within the spraying caution time, the scheduled spraying date is considered a candidate for the spraying warning date. Caution is particularly required when spraying agrichemicals on the edge of the target field (the side closest to the spraying caution zone).

[0057] (5) Determining harvest information (S144) The harvest time determination unit 2105 determines whether the crop can be harvested based on the number of days before harvest for each drug and each crop, and presents the result to the user. The number of days before harvest is the minimum number of days that must pass between the application of the drug and harvest. For example, if the number of days before harvest is 7 days, the crop can be harvested from the 7th day after the drug is sprayed. (5a) A day on which the number of days before harvest has passed from the scheduled spraying date is considered to be a harvestable day. (5b) A day on which the number of days before harvest has not passed from the scheduled spraying date is considered to be a harvest prohibited day. This is because the Agricultural Chemicals Control Act stipulates that crops cannot be harvested if the number of days before harvest has not passed since the drug was sprayed.

[0058] (6) Determining contamination information (S145) The contamination determination unit 2106 maps areas where spraying of pesticides is prohibited on a map based on the number of possible days after spraying and the prohibited range after spraying that are set for each pesticide, and presents the recommended spraying date and the prohibited spraying date to the user. When a pesticide is sprayed as a pesticide within a certain range (for example, within a 2 km range), if the pesticide is sprayed again without waiting for a certain period of time, there is a possibility that the amount of river pollution specified may be exceeded. Therefore, it is specified that pesticides should not be sprayed within that range unless a certain period of time is left. (6a) If the area is outside the prohibited range after spraying, or if the prohibited range after spraying is within the prohibited range after spraying, the area is set as a candidate for the recommended spraying date. (6b) If the area is within the prohibited range after spraying and the permitted range after spraying has not passed from the scheduled spraying date, the area is set as a prohibited spraying date. Note that if the prohibited range after spraying overlaps with a neighboring field, the longest possible number of days after spraying of the pesticide sprayed within each range is referenced for the judgment.

[0059] (7) Determination of drug sprayer information (S146) When a drone or other pesticide sprayer is used jointly by multiple farmers, the pesticide sprayer information determination unit 2107 makes the following determinations: (7a) Days that are not reserved by other farmers who are using the pesticide sprayer are considered as candidates for recommended spraying days. (7b) Days that are reserved by other farmers who are using the pesticide sprayer are considered as days when spraying is prohibited.

[0060] Based on the above viewpoints, the pesticide spraying plan creation support device 2 calculates days when pesticide may be sprayed in the target farm field, days when pesticide spraying is not permitted, and the like, and provides the results to the user terminals 3 and 4.

[0061] 9 is an example of the first screen G1 including a proposal of a chemical to be used for each target field. The first screen G1 includes, for example, a field map display section GP11 that displays a map of the target field to which the chemical is to be sprayed, a detail display section GP12 that shows details of the target field to be sprayed, and operation buttons GP13 and GP14.

[0062] For example, when a user such as an agricultural cooperative employee or a farmer selects a field on the field map display section GP11, detailed information of the selected field is displayed in the detail display section GP12. Detailed information of all fields, not just the selected field, may be displayed in the detail display section GP12.

[0063] The detailed information displayed in the detail display section GP12 includes, for example, the field ID, the owner's name, and information identifying the chemical to be sprayed. The contents of each item included in the detailed information can be edited. The user can change the contents of a desired item (for example, the ID of the chemical to be sprayed) by operating the edit button GP13.

[0064] When the user approves the target field and the chemical to be sprayed, the user operates the decision button GP14. This causes information on which chemical to be sprayed in which field to be sent to the chemical spraying plan creation support device 2.

[0065] Fig. 10 is an example of the second screen G2. The second screen G2 provides the user with candidate dates and times for spraying the pesticide for each target field. The second screen G2 includes, for example, a target field designation section GP21, a spraying date and time designation section GP22, a spraying time information display section GP23, and a decision button GP24. Fig. 11 shows an enlarged view of the spraying time information display section GP23 in Fig. 10.

[0066] The target field designation unit GP21 designates a target field through a user operation. The spraying date and time designation unit GP22 designates a date and time for spraying a chemical through a user operation. The spraying date and time may span multiple days.

[0067] The spraying time information display unit GP23 displays, for example, recommended spraying dates D1, spraying warning dates D2, and spraying prohibition dates D3 in a calendar format. Although not shown in the figure, it can also display harvestable dates D4 and harvesting prohibition dates D5. Here, three types of dates, recommended spraying dates D1, spraying warning dates D2, and spraying prohibition dates D3, are displayed so that the user can easily understand the appropriate time to spray the drug.

[0068] 11, the spraying time information display section GP23 includes, for example, a calendar GP230, and a recommended spraying date display section GP231, a spraying warning date display section GP232, a spraying prohibition date display section GP233, and a recommended spraying date (sales) display section GP234, which are displayed separately on the calendar 230. When the user selects a specific day on the calendar 230, the screen moves to a third screen G3, which will be described later, and details of the drug spraying plan are displayed.

[0069] The calendar 230 may be displayed, for example, in monthly units, or multiple months may be displayed simultaneously. The recommended spraying date display section GP231 indicates that days on which nothing is written on the calendar 230 are recommended spraying dates. The spraying warning date display section GP232 indicates that days shown in a cross-hatched frame on the calendar 230 are spraying warning dates. The prohibited spraying date display section GP233 indicates that days shown in a diagonal line frame on the calendar 230 are spraying prohibition dates. The recommended spraying date (sales) display section GP234 indicates that days shown in a white frame on the calendar 230 are days on which spraying should be performed from the perspective of crop sales. An embodiment in which the spraying date of the pesticide is determined from the perspective of sales will be described later.

[0070] When the user decides the date and time to spray the medicine, he / she operates the decision button GP24. As a result, information on when the medicine will be sprayed is sent to the medicine spraying plan creation support device 2.

[0071] FIG. 12 is an example of the third screen G3 including details of the drug dispersion plan requested from the user terminal 3, 4, predetermined dispersion conditions, and advice for meeting the predetermined dispersion conditions.

[0072] The third screen G3 shows detailed information about the pesticide spray plan, and includes, for example, a target field display section GP31, a spray date display section GP32, and a detailed information display section GP33. The detailed information display section GP33 displays details about the pesticide spray plan. The details include, for example, precautions and advice for spraying the pesticide. After checking the details of the pesticide spray plan, the user can operate the back button GP24 to return to the second screen G2.

[0073] According to this embodiment configured as described above, it is possible to assist in the efficient creation of a pesticide spraying plan that thoroughly considers all the various conditions that must be taken into account when spraying pesticide in a field.

[0074] According to the pesticide spraying plan creation support device 2 of this embodiment, it is possible to exchange information with users such as farmers or agricultural cooperative staff via multiple screens G1 to G3, while supporting the creation of a pesticide spraying plan that meets specified conditions, thereby improving usability for users.

[0075] In the pesticide spraying plan creation support device 2 of this embodiment, out of the multiple dates (recommended spraying date D1, spraying warning date D2, spraying prohibition date D3, harvestable date D4, harvest prohibition date D5) calculated when creating a pesticide spraying plan, the user is provided with the dates that are most closely related to pesticide spraying (recommended spraying date D1, spraying warning date D2, spraying prohibition date D3), allowing the user to easily grasp the temporal overview of the pesticide spraying plan, improving usability for the user. EXAMPLES

[0076] A second embodiment will be described with reference to the flowchart in Fig. 13. In this embodiment, differences from the first embodiment will be mainly described. Fig. 13 shows a process for calculating a recommended date for spraying a chemical based on consumer demand (sales of crops).

[0077] The pesticide spraying time suggestion unit 210 of the pesticide spraying plan creation support device 2 acquires sales information of sales outlets within a predetermined range from the target field (S200). Sales outlets are facilities that sell crops harvested from the target field, and include, for example, supermarkets, greengrocers, convenience stores, mobile sales trucks, etc.

[0078] The sales outlet is provided with a computer terminal, such as a POS (Point of Sales) register, that can transmit sales information to the medicine dispersion plan creation support device 2. The computer terminal may be a so-called smartphone.

[0079] The pesticide spraying time suggestion unit 210 compiles the sales information acquired from each sales outlet by crop type and day of the week (S201). Based on the compilation results, the pesticide spraying time suggestion unit 210 calculates the day of the week when the crop sales are expected to be the highest as the recommended sales day for that crop (S202). The pesticide spraying time suggestion unit 210 calculates the day when the recommended sales date and the harvest date match, and presents the calculated date to the user as the recommended pesticide spraying date based on sales (S203).

[0080] This embodiment configured in this way also has the same effect as the first embodiment. Furthermore, in this embodiment, the recommended date for spraying the pesticide is calculated so that the sales of the harvested crops will be increased, which brings about financial benefits to the farmer as the user. In addition to the most recent sales information of the sales outlet, sales information over several years may be obtained, and the recommended sales date for increasing sales may be obtained using a so-called machine learning model.

[0081] The present invention is not limited to the above-mentioned embodiment, and various modified examples are included. For example, the above-mentioned embodiment has been described in detail to explain the present invention in an easy-to-understand manner, and is not necessarily limited to those having all the described configurations. In addition, each of the above-mentioned configurations, functions, processing units, processing means, etc. may be realized in hardware by designing a part or all of them as an integrated circuit, for example. In addition, each of the above-mentioned configurations, functions, etc. may be realized in software by a processor interpreting and executing a program that realizes each function. Information such as a program, table, file, etc. that realizes each function can be placed in a memory, a recording device such as a hard disk or SSD (Solid State Drive), or a recording medium such as an IC card, SD card, or DVD.
