Description

Technical Field

[0001] The present invention relates to an agricultural support method and an agricultural support program.

Background Art

[0002] When cultivating crops in a field, the mechanical working direction (the direction in which the ridges extend) affects the quantity of crops that can be cultivated. For example, in a rectangular field, when the mechanical working direction is the long side direction, the area to be secured for turning is represented by, for example, "the length of the short side × the distance required for turning × 2". When the mechanical working direction is the short side direction, the area to be secured for turning is represented by, for example, "the length of the long side × the distance required for turning × 2". In this case, when the mechanical working direction is the long side direction, the field can be utilized more efficiently, so the quantity of crops that can be cultivated tends to increase.

[0003] On the other hand, recently, a technique for calculating the maximum number of seedlings for lands of various shapes, not limited to rectangular fields, is known (see, for example, Patent Document 1).

[0011] The following describes in detail one embodiment of the agricultural support system based on Figures 1 to 9. Figure 1 schematically shows the configuration of the agricultural support system 100 according to one embodiment. Farmers and other agricultural workers (hereinafter referred to as "producers") need to determine the direction of machine work (direction of the ridges) in the field when planting crops (vegetables, onions, etc.) that are planted by making ridges. The agricultural support system 100 of this embodiment is a system that provides producers with the necessary information when they determine the direction of machine work and supports producers in determining the direction of machine work. Machine work includes tasks such as planting seedlings and sowing seeds, and the direction of machine work includes the direction in which seedlings are planted (direction in which seedlings are lined up) and the direction in which seeds are sown.

[0012] As shown in Figure 1, the agricultural support system 100 comprises a server 10 as an agricultural support device and user terminals 70. The user terminals 70 are devices such as PCs (Personal Computers), tablet devices, and smartphones used by producers. The server 10 and user terminals 70 are connected to a network 80 such as the internet, enabling information exchange between the devices.

[0013] The user terminal 70 transmits the information entered by the producer to the server 10. Figure 2(a) shows the hardware configuration of the user terminal 70. As shown in Figure 2(a), the user terminal 70 includes a CPU (Central Processing Unit) 190, ROM (Read Only Memory) 192, RAM (Random Access Memory) 194, storage (here, an SSD (Solid State Drive) or HDD (Hard Disk Drive)) 196, a network interface 197, a display unit 193, an input unit 195, and a portable storage medium drive 199 capable of reading portable storage media 191. Each of these components of the user terminal 70 is connected to a bus 198. The display unit 193 includes a liquid crystal display, and the input unit 195 includes a keyboard, mouse, touch panel, etc.

[0014] Server 10 is a device that acquires information from user terminals 70, generates information useful for determining the machine work direction based on the acquired information, and outputs this information to user terminals 70 used by producers.

[0015] Figure 2(b) shows the hardware configuration of server 10. As shown in Figure 2(b), server 10 includes a CPU 90, a ROM 92, a RAM 94, a storage (here, SSD or HDD) 96, a network interface 97, a drive 99 for portable storage media, etc. Each component of the configuration of server 10 is connected to a bus 98. In server 10, the CPU 90 executes a program (including an agricultural support program) stored in the ROM 92 or HDD 96, or a program (including an agricultural support program) read by the drive 99 for portable storage media from the portable storage media 91, whereby the functions of each part shown in Figure 3 are realized. Note that the functions of each part in Figure 3 may be realized by an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

[0016] Figure 3 shows a functional block diagram of server 10. In server 10, when the CPU 90 executes a program, as shown in Figure 3, it functions as a calculation condition acquisition unit 20, a field information acquisition unit 21, a mechanical operation direction acquisition unit 22, a furrow arrangement identification unit 23, a crop quantity calculation unit 24, a working time calculation unit 25, and an output unit 26. Note that Figure 3 also shows a calculation condition storage unit 40 and a calculation result storage unit 42 stored in the storage 96 etc. of server 10.

[0017] The calculation condition acquisition unit 20 acquires the calculation conditions input to the input / output screen (input / output screen (2) in Figure 4(b)) displayed on the user terminal 70 and stores them in the calculation condition storage unit 40.

[0018] The field information acquisition unit 21 acquires the information (shape and size information) of the field specified in the input / output screen (input / output screen (1) in Figure 4(a)) displayed on the user terminal 70 and transmits it to the furrow arrangement identification unit 23.

[0019] The machine work direction acquisition unit 22 acquires the machine work direction specified on the input / output screen (input / output screen (1) in Figure 4(a)) displayed on the user terminal 70 and transmits it to the furrow arrangement identification unit 23.

[0020] The furrow arrangement identification unit 23 identifies the furrow arrangement within the field based on field information received from the field information acquisition unit 21, machine work direction information received from the machine work direction acquisition unit 22, and calculation conditions stored in the calculation condition storage unit 40.

[0021] The crop quantity calculation unit 24 calculates the number of seedlings planted (transplanted) in the field based on the furrow arrangement identified by the furrow arrangement identification unit 23 and the calculation conditions stored in the calculation condition storage unit 40. The crop quantity calculation unit 24 stores the calculated quantity in the calculation result storage unit 42.

[0022] The work time calculation unit 25 calculates the time required to plant throughout the entire field based on the furrow arrangement identified by the furrow arrangement identification unit 23 and the calculation conditions stored in the calculation condition storage unit 40. The work time calculation unit 25 stores the calculated time in the calculation result storage unit 42.

[0023] The output unit 26 reads the quantity calculated by the crop quantity calculation unit 24 and the time calculated by the work time calculation unit 25 from the calculation result storage unit 42 and outputs (transmits) them to the user terminal 70. The user terminal 70 displays the received information (quantity and time) on the input / output screen (input / output screen (2) in Figure 4(b)).

[0024] Here, the input / output screen will be explained based on Figures 4(a) to 6(b). Figure 4(a) shows input / output screen (1), and Figure 4(b) shows input / output screen (2). First, input / output screen (1) in Figure 4(a) is displayed on the user terminal 70, and when the "Next" button 110 is pressed, it transitions to input / output screen (2) in Figure 4(b). Also, when input / output screen (2) in Figure 4(b) is displayed, if the "Back" button 126 is pressed, it transitions to input / output screen (1) in Figure 4(a).

[0025] The input / output screen (1) in Figure 4(a) includes a field selection area 102, a field location information display area 104, a machine work direction specification area 106, a "Start Calculation" button 108, a "Next" button 110, and a "Cancel" button 112.

[0026] The field selection area 102 displays satellite imagery or a map, which can be scrolled, zoomed in and out, etc., by the producer. The producer can select a field by sequentially selecting the corners of the field (the four corners in Figure 6(a)) as shown in Figure 6(a).

[0027] As shown in Figure 6(b), the field location information display area 104 displays the location information (latitude and longitude) of the corner of the field specified by the producer.

[0028] The machine work direction specification area 106 is provided with checkboxes (short side, long side, and arbitrary) for specifying the machine work direction. If the "short side" checkbox is checked, the direction along the shortest side of the specified field will be specified as the machine work direction. If the "long side" checkbox is checked, the direction along the longest side of the specified field will be specified as the machine work direction. If the "arbitrary" checkbox is checked, the straight line direction with the two points specified by the producer as the start and end points will be specified as the machine work direction. In this case, the position information (latitude and longitude) of the start and end points will be displayed in the "Start Point" and "End Point" fields to the right of the "Machine Work Direction" display. Also, if the "Pest Control Ridge" checkbox is checked, a pest control ridge (described later) will be set up in the field.

[0029] The "Start Calculation" button 108 is pressed by the producer to begin the process of calculating the number of seedlings that can be planted in the field (number of plants) and the time required for planting. The "Next" button 110 is pressed by the producer to transition to the input / output screen (2), and the "Cancel" button 112 is pressed by the producer to cancel the work using the input / output screens (1) and (2).

[0030] The input / output screen (2) in Figure 4(b) includes an explanation area 120, a calculation condition input area 122, a calculation result display area 124, a "Back" button 126, and a "Cancel" button 128.

[0031] The explanation area 120 displays a diagram to explain the terms listed in the calculation condition input area 122. The calculation condition input area 122 also has input fields for entering various calculation conditions. Figure 5 shows an enlarged view of the explanation area 120. As shown in Figure 5, the distance between the center of one furrow and the center of an adjacent furrow is called "furrow spacing," the distance between seedlings arranged in the short direction of the furrow on the furrow is called "row spacing," and the distance between seedlings arranged in the long direction of the furrow on the furrow is called "plant spacing." The number of seedlings arranged in the short direction of the furrow on the furrow is called "row count." Furthermore, the dimensions of the area for agricultural machinery (planting equipment) located at both ends of the ridge in the longitudinal direction to turn (the longitudinal dimension of the ridge) are defined as "headland: both ends of the ridge," and the dimensions of the area between the ridge and the edge of the field at both ends in the short direction of the ridge (the short direction dimension of the ridge) are defined as "headland: sides of the ridge." In addition, the dimensions of the top surface of the ridge in the short direction are defined as "top surface of the ridge," and the width of the passage through which the pest control device that sprays chemicals for pest control moves is defined as "pest control ridge width." Moreover, the time required for the agricultural machinery to turn once is defined as "turning time," the time required for the agricultural machinery to move 1 meter is defined as "straight-line travel time," and the number of ridges that the sprayer of the pest control device can spray pesticide on at one time is defined as "number of ridges sprayed by the sprayer."

[0032] Figure 6(b) shows the state after the producer has entered values ​​in each field of the calculation condition input area 122.

[0033] Returning to Figure 4(b), the calculation result display area 124 has fields that display the number of seedlings that can be planted in the field (number of plants), the work time required for planting, and the information that the producer has entered or specified on the input / output screens (1) and (2).

[0034] The "Back" button 126 is pressed by the producer when transitioning to the input / output screen (1), and the "Cancel" button 128 is pressed by the producer when canceling work using the input / output screens (1) and (2).

[0035] (Regarding server 10 processing) Next, the processing of server 10 will be explained in detail, following the flowchart in Figure 7 and referring to other diagrams.

[0036] When the process shown in Figure 7 begins, first, in step S10, the server 10 (calculation condition acquisition unit 20, field information acquisition unit 21, machine work direction acquisition unit 22) waits until the "Start Calculation" button 108 is pressed, with the calculation conditions, field information, and machine work direction specified on the input / output screens (1) and (2) displayed on the display unit 193 of the user terminal 70. The producer enters values ​​into the calculation condition input area 122 of the input / output screen (2) in Figure 4(b), as shown in Figure 6(b). The producer also displays the target field by scrolling, zooming in and out, etc., in the field selection area 102 of the input / output screen (1) in Figure 4(a), and sequentially selects the corners of the field (the four corners in Figure 6(a)), as shown in Figure 6(a). As a result, the user terminal 70 identifies the location information (latitude, longitude) of the selected corners and displays it in the field location information display area 104. Furthermore, the manufacturer specifies the machine work direction in the machine work direction specification area 106. Here, as an example, the manufacturer checks the "long side" checkbox, as shown in Figure 6(a).

[0037] In this way, when the producer specifies the calculation conditions, field information, and machine work direction and presses the "Start Calculation" button 108, the user terminal 70 transmits the information entered on the input / output screens (1) and (2) to the server 10. At this stage, the judgment in step S10 of Figure 7 is affirmed, and the process proceeds to step S12. The calculation condition acquisition unit 20 stores the calculation condition information received from the user terminal 70 in the calculation condition storage unit 40. The field information acquisition unit 21 transmits the received field information (location information of the four corners, and information indicating the size and shape of the field) to the furrow arrangement identification unit 23. Furthermore, the machine work direction acquisition unit 22 transmits the received machine work direction information (in this case, "long side") to the furrow arrangement identification unit 23.

[0038] When the process moves to step S12 in Figure 7, the furrow arrangement specification unit 23 arranges furrows in the field. Specifically, as shown in Figure 8(a), the furrow arrangement specification unit 23 sets a furrow arrangement area as shown by the solid black line within the field shown by the white line. The furrow arrangement area is set based on the values ​​of "headland: both ends of furrow" and "headland: side of furrow" specified on the input / output screen (2), and the machine work direction specified on the input / output screen (1). In this case, the machine work direction is along side x, which is the longest side of the field in Figure 8(a), so dimension a becomes the value of "headland: both ends of furrow" (= 5m) and dimension b becomes the value of "headland: side of furrow" (= 1m).

[0039] Then, the furrow arrangement identification unit 23 arranges the furrows within the furrow arrangement area, as shown in Figure 8(b). At this time, the furrow arrangement identification unit 23 arranges the furrows along the machine work direction (side x direction) based on the "furrow spacing" value (=1.5m) and the "pest control furrow width" value (=2m) entered in the input / output screen (2). If the value of "number of furrows to spray with sprayer" is 5, a pest control furrow is provided every 10 furrows, as shown in Figure 8(b). In the example in Figure 8(b), 45 furrows are arranged.

[0040] Returning to Figure 7, in the next step S14, the crop quantity calculation unit 24 calculates the length of the ridges and the number of plants to be planted. The length of the ridges is the total length of the ridges shown in Figure 8(b). The crop quantity calculation unit 24 determines the number of plants to be planted using the following equation (1). Number of plants to plant = furrow length (m) × 100 (cm) × number of rows (plants) / spacing between plants (cm) …(1)

[0041] For example, suppose the length of the furrow is 2821m, the number of rows is 4, and the spacing between plants is 12cm. In this case, using the above formula (1), the number of plants to be planted is 2821 × 100 × 4 / 12 = 94033. The crop quantity calculation unit 24 stores the calculated number of plants to be planted in the calculation result storage unit 42.

[0042] Next, in step S16, the work time calculation unit 25 calculates the work time based on the length of the furrows, etc. Specifically, the work time calculation unit 25 calculates the work time using the following formula (2). Working time (minutes) = Turning time (minutes / turn) × (Number of rows - 1) +Row length (m) × Straight-line travel time (min / m) …(2)

[0043] For example, if the length of the furrow is 2821m, the number of furrows is 45, the turning time is 1 minute / turn, and the straight-line time is 10 minutes / m, the working time is calculated as 1 × 44 + 2821 / 10 ≈ 326 (minutes). The working time calculation unit 25 stores the calculated working time in the calculation result storage unit 42.

[0044] Next, in step S18, the output unit 26 reads the number of plants and the working time from the calculation result storage unit 42 and outputs them to the user terminal 70. As a result, the number of plants and the working time are displayed on the input / output screen (2), as shown in Figure 9.

[0045] Next, in step S20, the server 10 (calculation condition acquisition unit 20) determines whether the input information has been changed on the input / output screens (1) and (2) displayed on the display unit 193 of the user terminal 70, and whether the "Start Calculation" button 108 has been pressed again. If the determination in step S20 is negative, the process moves to step S22, where the server 10 (calculation condition acquisition unit 20) determines whether the process is finished or not (whether the producer has pressed the "Cancel" button 112 or 128). If the determination in step S22 is positive, the process in Figure 7 is completed, but if it is negative, the process returns to step S20.

[0046] If the judgments in steps S20 and S22 are consistently denied, and then the judgment in step S20 is affirmed, the process returns to step S12.

[0047] Returning to step S12, the processes from steps S12 to S18 are executed again based on the information entered in the input / output screens (1) and (2). For example, if the machine's working direction is changed, the number of plants to be planted and the working time are calculated using the changed machine working direction and displayed on the input / output screen (2). Also, for example, if the "Pest Control Ridge" checkbox is checked in the screen shown in Figure 6(a) and then the "Start Calculation" button 108 is pressed, ridges will be added to the pest control ridges in Figure 8(b). In other words, in the example of Figure 8(b), the number of ridges increases by 4, so the number of plants to be planted and the working time will increase.

[0048] Here, the calculation result storage unit 42 sequentially stores the calculated number of plants and working time. Therefore, the number of plants and working time may be displayed in a comparable manner upon request from the user terminal 70 (producer). In this case, if the producer inputs multiple machine working directions, displaying the combination of machine working direction, number of plants, and working time in a comparable manner allows the producer to check which machine working direction will result in a larger number of plants and which machine working direction will result in a shorter working time. This makes it easier for the producer to select a machine working direction.

[0049] In this case, for example, the machine operation direction that maximizes quantity and the machine operation direction that minimizes working time may be displayed in a different manner from other machine operation directions (e.g., by using different font colors or font sizes). This makes it easier for producers to select the machine operation direction.

[0050] As described in detail above, according to this embodiment, the field information acquisition unit 21 acquires information on the shape and size of the field, and the machine work direction acquisition unit 22 acquires the machine work direction of the crops. The furrow arrangement identification unit 23 identifies the planting locations (furrow arrangement) based on the machine work direction and crop planting interval (furrow spacing) information, as well as the field shape and size information (S12), and the crop quantity calculation unit 24 calculates the total number of crops that can be planted in the entire field (number of plants) (S14). The work time calculation unit 25 calculates the time required to plant crops in the entire field (work time) based on the speed information of the agricultural machinery (turning time, straight-line time) and the planting locations (furrow arrangement) (S16), and the output unit 26 outputs the quantity and work time (S18). This allows producers to determine the machine's working direction while confirming the different planting numbers and working times for each direction. In this case, producers can determine the machine's working direction while considering whether to prioritize the planting number or the working time. Therefore, the server 10 can provide useful information for producers to determine the appropriate machine working direction. Furthermore, since the planting number is known in advance, yield prediction can be made by multiplying the planting number by the yield per plant.

[0051] Furthermore, for example, when planting seedlings in a field using manually operated agricultural machinery, if the number of planted seedlings is detected using sensors and the time required for the work is measured, it is possible to compare this with the number of planted seedlings and the work time calculated by the server 10 to determine how much the number of planted seedlings was too low or how much the work time was too long. If, as a result of this check, the number of planted seedlings was too low or the work time was too long (for example, if the agricultural machinery could not be driven in a straight line as planned), then the introduction of automated agricultural machinery should be considered. In addition, when automated agricultural machinery is introduced, the furrow arrangement of the above embodiment may be used to generate the movement path of the agricultural machinery.

[0052] Furthermore, in this embodiment, the furrow arrangement is determined by considering the width of the pest control furrows and the number of furrows sprayed by the sprayer, and the number of plants to be planted and the work time are calculated, so the furrow arrangement, the number of plants to be planted and the work time in the field can be predicted with high accuracy.

[0053] In the above embodiment, the case of displaying the number of plants and working time was described, but the system is not limited to this. An index value indicating the efficiency of planting may be calculated from the number of plants and working time, and the calculated index value may be displayed. For example, the index value can be expressed as the number of plants divided by working time.

[0054] (modified version) In the above embodiment, we have described the case in which the number of plants to be planted and the working time are calculated and displayed, but in addition to this, a loss index may also be calculated and presented. The loss index is an index that shows the amount of the number of plants that will be lost if it becomes impossible to plant in one furrow.

[0055] For example, the average length of one furrow can be calculated using the following equation (3). Average length of one furrow (m) = total length of furrow (m) / number of furrows …(3)

[0056] Then, the loss index is determined as "1" if the average length (m) of one furrow is 0-50m, "2" if it is 50-100m, and "3" if it is 100m or more, and this is displayed on the input / output screen (1) or input / output screen (2).

[0057] This allows producers to determine the direction of machine operation based on the loss index. Furthermore, since a higher loss index requires greater straight-line movement of agricultural machinery, robotic tractors or similar equipment should be used when employing machine operation directions with a high loss index.

[0058] In addition to the loss indicator, it is also possible to calculate the number of plants lost when, for example, it becomes impossible to plant in one furrow, and display this on the input / output screen (1) or input / output screen (2). In this case, the number of plants lost can be calculated from the following equation (4). Number of plants lost during planting = Average length of one furrow (m) × Number of rows / Spacing between plants (m) ... (4)

[0059] Furthermore, the percentage of plants lost when planting in one furrow becomes impossible (loss rate (%)) may be calculated and displayed on the input / output screen (1) or input / output screen (2). In this case, the number of plants lost can be calculated from the following equation (5). Loss rate (%) = Number of plants lost × 100 / Number of plants ... (5)

[0060] Figure 10 shows an example where the loss indicator, the number of plants lost, and the loss rate (%) are displayed on the input / output screen (2).

[0061] Furthermore, the above embodiment can be applied not only to crops that require ridge formation (such as vegetables and onions), but also to crops such as rice and wheat.

[0062] The embodiments described above are preferred examples of the present invention. However, the invention is not limited thereto, and various modifications are possible without departing from the spirit of the invention. [Explanation of symbols]
