As growth conditions, FIGS. 3A to 3E show the plant height (vegetation index) of the crop as an example, and FIG. 3F shows the amount of shirata rice contained in the harvested rice as an example. is not limited.

As shown in FIG. 3A, the growth prediction unit 12 shows the transition W1 of the plant height when tilling is performed during the period from 4/10 to 4/19, and the period from 3/29 to 4/10. and the transition W3 of the plant height when tilling is performed after 4/20. In this case, the plan creation unit 13 selects, for example, the transition W1 in which the plant height is the longest as the best transition (pattern) of the plant height, and tills during the period from 4/10 to 4/19 corresponding to the transition W1. set that.

As shown in FIG. 3B, the growth prediction unit 12 predicted the transition W4 of plant height when puddling was performed during the period from April 10 to 19, and the transition W5 of plant height when puddling was not performed. and In this case, the plan creating unit 13 selects the transition W4 as the best transition of plant height, and sets that puddling is to be performed during the period from 4/20 to 4/30 corresponding to the transition W4.

As shown in FIG. 3C, the growth prediction unit 12 shows the transition W6 of the plant height when basal fertilizer (fertilizer application) was performed during the period from April 25 to May 5, and the plant height when basal fertilizer (fertilizer application) was not performed. Suppose that the plant height transition W7 is predicted. In this case, the plan creating unit 13 selects transition W6 as the best transition of plant height, and sets basal fertilizer (fertilizer application) to be performed during the period from April 25 to May 5 corresponding to the transition W6.

As shown in FIG. 3D, the growth prediction unit 12 indicates the transition W8 of the plant height when rice was planted during the period from May 1 to May 9, and the tillage during the period from May 10 to May 19. and a plant height transition W10 when plowing is performed after 5/20. In this case, the plan creation unit 13 selects the transition W8 as the best transition of the plant height, and sets the rice planting to be performed during the period from May 1 to May 9 corresponding to the transition W8.

As shown in FIG. 3E, the growth prediction unit 12 changes the plant height W11 when agricultural chemicals were sprayed during the period from June 15 to June 30, and tilled during the period from July 1 to July 9. It is assumed that the transition W12 of the plant height in the case of 7/10 and the transition W13 of the plant height in the case of tilling after 7/10 are predicted. In this case, the plan creation unit 13 selects the transition W11 as the best transition of the plant height, and sets the agricultural chemical spraying to be performed during the period from June 15 to June 30 corresponding to the transition W11.

In the above example, the plan creation unit 13 selects the best plant height transition as the best plant height transition, but it is not limited to this. For example, the plan creation unit 13 may select another plant height transition state, such as the transition in which the plant height is the least elongated or the transition in which the plant height is increased by a predetermined length, as the best transition of the plant height.

As shown in FIG. 3F, the growth prediction unit 12 predicts the change W14 of the amount of shirata rice when harvesting is performed from 9/1 to 9/15, and It is assumed that a transition W15 of the amount of shirata rice when harvesting is performed and a transition W16 of the amount of shirata rice when harvesting is performed after 10/11 are predicted. In this case, the plan creation unit 13 selects the transition W15 with the smallest amount of shirata rice as the best pattern, and sets harvesting to be performed during the period from 9/16 to 10/10 corresponding to the transition W15.

FIG. 4 shows an example of a farm work plan created by the plan creation unit 13. FIG. The plan creation unit 13 selects the optimum time for carrying out farm work based on the growth conditions of the crops predicted by the growth prediction unit 12, and creates a farm work plan for carrying out the farm work as shown in FIG. .

Further, when the farm worker or administrator performs a predetermined operation on the external terminal 20, the external terminal 20 acquires the plan information from the management device 10, and displays the farm work plan on the display unit 21 based on the plan information. to display.

<Sharing>
<Registration of agricultural machinery, etc.>
The agricultural support system 100 supports sharing of agricultural machines such as a tractor 31, a rice transplanter 32, and a combine 33 (see FIG. 2) used in farm work. The management device 10 registers a plurality of lendable agricultural machines by receiving information on lendable agricultural machines, and shares agricultural machines necessary for farm work among farm workers in a predetermined area. Assist.

For example, the management device 10 includes a registration unit 14 and a machine storage unit 15. The registration unit 14 is configured by an electrical/electronic circuit or program provided in the management device 10 . The registration unit 14 registers in the management device 10 information about agricultural machines and the like used in farm work. The machine storage unit 15 is composed of a non-volatile memory and stores information regarding a plurality of agricultural machines.

When an external terminal 20 such as a smartphone, tablet, notebook computer, or personal computer is connected to the management device 10 and a predetermined operation is performed on the external terminal 20, the registration unit 14 registers the agricultural machine as shown in FIG. and a screen (registration screen) M1 for registering the owner is displayed on the external terminal 20 . On the registration screen M1, owner information of the agricultural machine (for example, name, address, email address, telephone number, etc.) and agricultural machine information on the agricultural machine (for example, type of agricultural machine (tractor, combine, rice transplanter, (sprayer, lawn mower, etc.), agricultural machine manufacturer, model number, appearance picture, etc.) can be input.

After the farm worker performs a predetermined operation on the external terminal 20 and inputs the owner information and the agricultural machine information in the predetermined input fields of the registration screen M1, the input contents are determined ("OK" in the registration screen M1). key). Then, the registration unit 14 causes the machine storage unit 15 to store (register) the owner information and the machine information input on the registration screen M1 in association with each other. By repeatedly executing this information registration procedure, registration information including a plurality of pieces of agricultural machine information and owner information associated with each piece of agricultural machine information as shown in FIG. stored as

In the registration screen M1 of FIG. 5, a predetermined area (city, town, village, union, etc.) for farming is defined as one community (community), and only farmers who belong to the community can register agricultural machine information and owner information. Alternatively, any farmer may be allowed to register agricultural machinery information and owner information regardless of community.

<Requirements for Agricultural Machinery>
The external terminal 20 ( FIG. 1 ) has a display section 21 and a machine request section 22 . The display unit 21 can display various information, and is composed of a liquid crystal panel, organic EL, or the like. As shown in FIG. 4 , the display unit 21 can display a farm work plan (farm work plan) created by the plan creation unit 13 . The farm worker refers to the farm work plan and decides the agricultural machine to be used in the field H1 and the date and time to use the agricultural machine. If the number of agricultural machines required for farm work is insufficient, or if the farm worker does not own the agricultural machines required for farm work, the farm worker operates the external terminal 20 to make a borrowing request for agricultural machines ( request for borrowing) to the management device 10 .

The machine request unit 22 is composed of an electric/electronic circuit or program provided in the external terminal 20. The machine requesting unit 22 selects a used machine, which is an agricultural machine used for farm work, from among a plurality of agricultural machines stored in the machine storage unit 15 of the management device 10 and the borrowing time (borrowing request) of the used machine days).

For example, when a farm worker or the like who wants to rent an agricultural machine performs a predetermined operation on the external terminal 20, the machine requesting unit 22 causes the display unit 21 to display the input screen M2 shown in FIG. The input screen M2 is a screen for inputting borrowing information for borrowing a working machine, which is an agricultural machine that a farm worker or the like wants to use in farm work. The borrowing information includes personal information Q1 and desired information Q2. The personal information Q1 includes the name, address, e-mail address, and telephone number of the farm worker. The desired information Q2 includes the type of machine to be used, the number of machines, and the rental time. Input fields for inputting these pieces of information are respectively provided on the input screen M2. Among them, in the input field for borrowing time, any one of the time, time period, date, and period for which the agricultural machine is to be borrowed can be entered. Note that the debit information is not limited to the above information.

After the farm worker performs a predetermined operation on the external terminal 20 to input the personal information Q1 and the desired information Q2 on the input screen M2, the input contents are determined (select the "OK" key in the input screen M2). do. Then, the machine requesting unit 22 transmits the personal information Q1 and the desired information Q2 input on the input screen M2 to the management device 10 .

It is preferable that the borrowing request for the machine to be used by the external terminal 20 as described above can be made only at a predetermined time or more (for example, one week before) before the time at which the machine is to be borrowed. In addition, a deadline for requesting the borrowing of a machine to be used may be set for each agricultural work indicated in the agricultural work plan created by the plan creating unit 13 of the management device 10, and the borrowing request by the external terminal 20 may be restricted. good.

<Adjuster>
The management device 10 has an adjustment unit 18 . The adjustment unit 18 is composed of an electric/electronic circuit, a program, or the like provided in the management device 10 . When the management device 10 receives the borrowing request for the used machine transmitted from the machine requesting unit 22 of the external terminal 20, the adjusting unit 18 stores the borrowing request in the machine storage unit 15, and based on the borrowing request. Organize the machine sharing situation. Further, the adjustment unit 18 causes the data storage unit 11 provided in the management device 10 or other storage units to store the sharing information indicating the sharing status of the organized agricultural machines.

After that, when the farm worker or the like performs a predetermined operation on the external terminal 20, the external terminal 20 acquires (receives) the sharing information indicating the sharing status of the agricultural machines organized by the adjustment unit 18 from the management device 10. do. Based on the sharing information, the external terminal 20 causes the display unit 21 to display a confirmation screen M3 showing the sharing status of the agricultural machine as shown in FIG.

The confirmation screen M3 displays the type and number of agricultural machines stored (registered) in the machine storage unit 15 of the management device 10, that is, the agricultural machines owned by the community. In addition, among the agricultural machines, the borrowing request status (a list showing the number of borrowing requests for each date and each applicant) of the machines to be used for which borrowing requests have been made during a predetermined period is also displayed on the confirmation screen M3. Specifically, in the example shown in FIG. 8, in the agricultural work plan created by the plan creation unit 13 of the management device 10, the desired number of tractors to be borrowed during the period of tillage work (April 10 to April 19) is A list is displayed for each date and for each farm worker A to G.

By performing a predetermined operation on the external terminal 20 and selecting one of the numbers indicating the number of machines to be borrowed on the confirmation screen M3, the debit information (personal information Q1 and desired information Q2 in FIG. 6) corresponding to the number is selected. ) is displayed on the display unit 21 . At this time, as shown in FIG. 6, the display unit 21 may display a screen showing only the debit information column in the input screen M2. As a result, the personal information Q1 of the person who wishes to borrow the machine to be used corresponding to the selected number and the desired borrowing information Q2 including the borrowing time can be visually recognized on the display unit 21 .

The adjustment unit 18 adjusts at least one of the used machine, the borrowed time, and the farm work plan when the borrowed machine cannot be rented during the borrowed time.

In the example shown in FIG. 8, while the number of tractors owned by the community is 10, the number of tractors requested to borrow is The total exceeds the number of vehicles owned. In such a case, the adjustment unit 18 determines that the number of machines to be borrowed is greater than the number of machines that can be rented on 4/12, 4/14, and 4/16, which are the borrowing times (desired borrowing dates). It is determined that some of the machines used cannot be rented during the borrowed time.

As described above, if the adjustment unit 18 determines that some of the machines cannot be rented during the borrowing hours of 4/12, 4/14, and 4/16, the tilling work period indicated in the farm work plan From April 10th to April 19th, we will change the borrowing time of some machines. Specifically, first, the adjusting unit 18 focuses on the total number of borrowed machines for each day of the tillage work period. Then, the adjustment unit 18 shifts the desired number of borrowed machines for which the borrowing time is on a day when the total number of machines desired to be borrowed is greater than the number of machines owned, to a day when the total number of machines desired to be borrowed is less than the number of machines owned. Change the borrowing time of some of the machines used.

Specifically, for example, the adjustment unit 18 transfers the three tractors that the farm worker A wishes to borrow on April 16th as shown in FIG. 8 to April 15th as shown in FIG. Change the borrowing time of 3 tractors. In addition, the adjustment unit 18 transfers the one tractor that the farm worker B has requested to borrow on April 12th as shown in FIG. 8 to April 13th as shown in FIG. Change the borrowing time. Furthermore, the adjustment unit 18 shifts the two tractors that the farm worker E requested to borrow on April 14 as shown in FIG. 8 to April 15 as shown in FIG. Change the borrowing time.

When the borrowing time of the machine used is changed as described above, the adjustment unit 18 stores the sharing information indicating the sharing situation reflecting the change in the data storage unit 11 of the management device 10 or another storage unit. After that, the external terminal 20 acquires the sharing information from the management device 10 by performing a predetermined operation on the external terminal 20 by a farm worker or the like, and based on the sharing information, an agricultural system as shown in FIG. The display unit 21 is caused to display a confirmation screen M3 showing the sharing status after the borrowing time of the machine is changed.

In addition, when the borrowing time of the machine to be used is changed as described above, the adjustment unit 18 notifies the person who wishes to borrow the machine to be used (such as a farm worker) of the details of the change. More specifically, for example, the adjustment unit 18 can be controlled by the external terminal 20 owned by the applicant for borrowing, the external terminal 20 operated by the applicant for the borrowing machine at the time of the borrowing request (the external terminal 20 that has sent the borrowing request). , or to the e-mail address (see FIG. 5) of the borrower who wishes to borrow, notifies (sends) borrowing change information indicating the content of the change in the borrowing time of the machine to be used.

Specifically, in the example shown in FIGS. 8 and 9, the coordinator 18 sends the external terminal 20 owned by the farm worker A, etc., the desired borrowing dates of the three machines on 4/16 to 4/16. 15 is notified.
