The technology described in Patent Document 1 discloses a technique for determining work data to be used for work based on the position information of a work device. However, there are cases where the field on which work will be performed cannot be identified before the work device enters the field.

(Embodiment 1)
A data management system 1000 according to the present embodiment of the present invention will be described with reference to the drawings. In this embodiment, as shown in Fig. 1, the data management system 1000 includes a data management device 100 and a terminal 200. The data management device 100 is communicably connected to the terminal 200 and a working device 30 via a network 20, for example, the Internet.

The data management device 100 generates work data 300 for the work device 30 to perform work. For example, as shown in FIG. 2, the work data 300 represents the amount of work to be performed on small areas 510 obtained by dividing the field 400 into a mesh shape. For example, if the work data 300 is fertilization data for fertilization by spreading fertilizer, the work data 300 represents the amount of fertilizer to be spread on each of the multiple small areas 510, for example, the amount spread per unit area. Also, if the work data 300 is pesticide spraying data for spraying pesticide, the work data 300 represents the amount of pesticide to be spread on each of the multiple small areas 510, for example, the amount spread per unit area. Note that the work data for fertilization by spreading fertilizer is sometimes called a fertilization map.

The working device 30 moves through the field 400 and performs work based on the work data 300. For example, the working device 30 is equipped with a positioning device, such as a GNSS (Global Navigation Satellite System) receiver, and performs work according to the position of the working device 30. Specifically, the working device 30 detects a small area 510 in the work data 300 that includes a position measured by the positioning device, and performs work based on the amount of work (e.g., the amount of spraying) set in the detected small area 510. For example, the working device 30 acquires the position of the working device 30 from the positioning device, and acquires the amount of fertilizer to be sprayed based on the acquired position and the work data 300. The working device 30 sprays fertilizer on the field 400 based on the acquired amount of spraying. The working device 30 includes a tractor that pulls a spraying machine that sprays fertilizer or pesticides, a drone that sprays pesticides, and the like.

When the work device 30 moves through the field 400 to perform work, the worker sets the work data 300 corresponding to the field 400 in the work device 30. For example, as shown in FIG. 3, the work device 30 performs work in the first field 400-1, the second field 400-2, the third field 400-3, and the fourth field 400-4. In this case, in order to perform work in the first field 400-1, the worker sets the work data 300 corresponding to the first field 400-1 in the work device 30 when starting work in the first field 400-1. When the work device 30 finishes work in the first field 400-1, the worker sets the work data 300 corresponding to the second field 400-2 in the work device 30 in order for the work device 30 to perform work in the second field 400-2. In this way, immediately before starting work in each field 400, the worker must set the corresponding work data 300 in the work device 30.

Here, the data management device 100 generates integrated work data that integrates the work data 300 corresponding to multiple fields 400. For example, the integrated work data includes work data 300 corresponding to the first field 400-1, work data 300 corresponding to the second field 400-2, work data 300 corresponding to the third field 400-3, and work data 300 corresponding to the fourth field 400-4. When working in the field 400, the worker sets the integrated work data in the work device 30. In this case, when the work device 30 finishes work in the first field 400-1 and starts work in the second field 400-2, the integrated work data including the work data 300 corresponding to the second field 400-2 is set in the work device 30. Therefore, immediately before starting work in the second field 400-2, the worker starts work in the second field 400-2 without setting the work data 300 corresponding to the second field 400-2 in the work device 30.

In this way, the data management system 1000 generates integrated work data that integrates the work data 300 corresponding to multiple fields 400, allowing workers to efficiently perform work in multiple fields 400.

(Data Management System Configuration)
The configuration of the data management device 100 included in the data management system 1000 will be described. As shown in FIG. 1, the data management device 100 includes an input/output device 110, a calculation device 120, a communication device 130, and a storage device 140. The data management device 100 is, for example, a computer. Information for the calculation device 120 to execute processing is input to the input/output device 110. The input/output device 110 outputs the results of the processing executed by the calculation device 120. The input/output device 110 includes various input devices and output devices, such as a keyboard, a mouse, a microphone, a display, a speaker, and a touch panel. The input/output device 110 may be omitted.

The communication device 130 is electrically connected to the network 20 and communicates with each device via the network 20. The communication device 130 transfers signals received from the terminal 200 to the calculation device 120. The communication device 130 also transfers signals generated by the calculation device 120 to the terminal 200. The communication device 130 includes various interfaces, such as a NIC (Network Interface Card) and a USB (Universal Serial Bus).

The storage device 140 stores various data for generating integrated work data, such as work data 300, and a data management program 310. The storage device 140 is used as a non-transitory tangible storage medium for storing the data management program 310. The data management program 310 may be provided as a computer program product recorded on a computer-readable storage medium 1, or may be provided as a computer program product downloadable from a server.

As shown in FIG. 2, the work data 300 represents the amount of work (e.g., the amount of spraying) for a plurality of small areas 510 divided by a first line segment 511 extending in a first direction and a second line segment 512 extending in a second direction. The first direction represents, for example, a north-south direction, more specifically, the direction in which a meridian extends, and the first line segment 511 extends, for example, along the meridian. The second direction represents, for example, an east-west direction, more specifically, the direction in which a latitude line extends, and the second line segment 512 extends, for example, along the latitude line. The first distances 521 representing the length of each small area 510 in the first direction are equal to each other. The second distances 522 representing the length of each small area 510 in the second direction are also equal to each other. The second distances 522 may be equal to or different from the first distances 521. The first distances 521 may be represented by the longitude difference between adjacent first line segments 511. The second distance 522 may be represented by the difference in latitude between adjacent second line segments 512.

The work data 300 has position information of a reference position 520 that indicates the position of the area of the work data 300, for example, information indicating latitude and longitude. The reference position 520 indicates, for example, the intersection of a first line segment 511 that is furthest in the first direction and a second line segment 512 that is furthest in the second direction within the area represented by the work data 300. The range of each small area 510 is represented by the reference position 520, a first distance 521, a second distance 522, and the position of the small area 510 in the work data 300.

The work data 300 is generated in advance. For example, the work data 300 is generated based on a yield map that represents the yield harvested in the previous year by averaging it for each small area. For example, the work data 300 is generated so that the amount of fertilizer sprayed on small areas with low yields is greater than the amount of fertilizer sprayed on small areas with high yields. The work data 300 may also be generated based on a growth map that represents the NDVI (Normalized Difference Vegetation Index) information acquired by an imaging device mounted on a drone before harvesting by averaging it for each small area.

The computing device 120 shown in FIG. 1 reads and executes the data management program 310 from the storage device 140, and performs various data processing to generate integrated work data. For example, the computing device 120 includes a central processing unit (CPU) and the like.

The computing device 120 reads and executes the data management program 310 to realize a data storage unit 150, a data generation unit 160, and an output unit 170, as shown in FIG. 4. The data storage unit 150 stores work data 300. The data generation unit 160 generates integrated work data based on the work data 300. The output unit 170 outputs the integrated work data generated by the data generation unit 160 to the terminal 200.

The data generation unit 160 includes a data area determination unit 162 and a work data setting unit 164. The data area determination unit 162 determines the area represented by the integrated work data based on the area of the field 400 where the work is to be performed. The work data setting unit 164 sets the amount of work in the integrated work data based on the work data 300.

5, the integrated work data 600 represents the amount of work to be performed on an integrated small area 610 surrounded by a first integrated line segment 611 extending in a first direction and a second integrated line segment 612 extending in a second direction. The first direction in which the first integrated line segment 611 of the integrated work data 600 extends is the same as the first direction in which the first line segment 511 of the work data 300 extends, and the first integrated line segment 611 extends, for example, along a meridian. The second direction in which the second integrated line segment 612 of the integrated work data 600 extends is the same as the second direction in which the second line segment 512 of the work data 300 extends, and the second integrated line segment 612 extends, for example, along a latitude line.

The first integrated distance 621 represents the distance of the integrated small area 610 in the first direction and may be represented by the longitude difference between adjacent first integrated line segments 611. The second integrated distance 622 represents the distance of the integrated small area 610 in the second direction and may be represented by the latitude difference between adjacent second integrated line segments 612. The first integrated distances 621 of each integrated small area 610 have equal latitude differences. Also, the second integrated distances 622 of each integrated small area 610 have equal longitude differences. Also, the first integrated line segment 611 and the second integrated line segment 612 may be provided so that the sizes of each integrated small area 610 are equal to each other. Also, the first integrated distances 621 of each integrated small area 610 may be equal to each other. Also, the second integrated distances 622 of each integrated small area 610 may be equal to each other.

The integrated work data 600 has position information, such as information representing latitude and longitude, of an integrated reference position 620 that represents the position of the area of the integrated work data 600. The integrated reference position 620 represents, for example, the intersection of a first integrated line segment 611 that is closest to the first direction and a second integrated line segment 612 that is closest to the second direction within the area represented by the integrated work data 600.

Next, the configuration of the terminal 200 will be described. As shown in FIG. 1, the terminal 200 includes an input/output device 210, a computing device 220, a communication device 230, and a storage device 240. The terminal 200 includes, for example, a computer, a tablet, a mobile phone, and the like. Information for the computing device 220 to execute processing is input to the input/output device 210. The input/output device 210 also outputs the results of the processing executed by the computing device 220. The input/output device 210 includes various input devices and output devices, and includes, for example, a keyboard, a mouse, a microphone, a display, a speaker, a touch panel, and the like.

The communication device 230 is electrically connected to the network 20 and communicates with each device via the network 20. The communication device 230 transfers information acquired from the data management device 100 to the calculation device 220. The communication device 230 also transfers signals generated by the calculation device 220 to the data management device 100. The communication device 230 includes various interfaces, such as a NIC (Network Interface Card) and a USB (Universal Serial Bus).

The storage device 240 stores various data, such as the setting program 320, for setting the integrated work data 600 in the work device 30. The storage device 240 is used as a non-transitory tangible storage medium for storing the setting program 320. The setting program 320 may be provided as a computer program product recorded on a computer-readable storage medium 2, or may be provided as a computer program product downloadable from a server. The setting program 320 may be provided by being recorded on a storage medium 1.

The computing device 220 reads and executes the setting program 320 to perform various data processing for setting the integrated work data 600 in the work device 30. The computing device 220 includes, for example, a central processing unit (CPU; Central Processing Unit) and the like.

When the computing device 220 reads and executes the setting program 320, it cooperates with the input/output device 210 to realize the setting unit 250 as shown in FIG. 4. The setting unit 250 accepts a request operation to generate integrated work data 600 corresponding to multiple fields 400. The setting unit 250 also acquires the integrated work data 600 from the data management device 100 and sets it in the work device 30.

(Data Management System Operation)
1 executes a data management program 310 when the data management device 100 is started. In addition, an operator inputs a start-up operation for starting a setting program 320 to an input/output device 210 of a terminal 200. When an input operation by the operator is input, the calculation device 220 of the terminal 200 executes the setting program 320 and starts the process shown in FIG 6, which is a data management method.

In step S110, the setting unit 250 realized by the calculation device 220 accepts a request operation for the integrated work data 600. For example, the setting unit 250 outputs information representing the fields 400 registered in the data management device 100. The worker inputs a request operation to the input/output device 210 to select multiple fields 400 corresponding to the integrated work data 600 to be generated from the output information. Based on the request operation, the setting unit 250 transmits request information representing the fields 400 corresponding to the integrated work data 600 to the data management device 100. The setting unit 250 may transmit request information for generating the integrated work data 600 for the registered fields 400 without a selection operation being input by the worker.

In step S120, the data area determination unit 162 of the data management device 100 determines the area of the integrated work data 600. For example, the data area determination unit 162 determines the integrated reference position 620 shown in FIG. 5. For example, the data area determination unit 162 determines the intersection of the second integrated line segment 612 passing through the point of the selected field 400 that is closest to the first direction and the first integrated line segment 611 passing through the point of the selected field 400 that is closest to the second direction as the integrated reference position 620.

The data area determination unit 162 also determines a first integrated distance 621 and a second integrated distance 622. For example, the data area determination unit 162 determines the minimum value of the first distances 521 of the small areas 510 in the multiple work data 300 corresponding to the selected field 400 as the first integrated distance 621. The second integrated distance 622 is also determined to be the minimum value of the second distances 522 of the small areas 510 in the multiple work data 300 corresponding to the selected field 400.

Furthermore, the data area determination unit 162 determines the distance in the first direction and the distance in the second direction of the integrated work data 600 to be generated. For example, the data area determination unit 162 determines a distance that is an integer multiple of the first integrated distance 621 and includes all areas of the selected field 400 as the distance in the first direction of the integrated work data 600. In addition, the distance in the second direction of the integrated work data 600 is determined to be a distance that includes all areas of the selected field 400.

The data area determination unit 162 sets an initial value as the amount of work for the integrated small area 610 of the integrated work data 600. The initial value is a value that indicates that no work is to be performed, for example, 0. The initial value may also be the minimum value at which the work device 30 can perform work.

In step S130 shown in FIG. 6, the work data setting unit 164 sets the work data 300 of the target field 400 to the integrated work data 600. Specifically, the work data setting unit 164 sets the amount of work set in the small area 510 of the work data 300 of the field 400 shown in FIG. 2 to the integrated small area 610 of the integrated work data 600 corresponding to the small area 510 shown in FIG. 5.

The work data setting unit 164 sets the work data 300 of the field 400 to the integrated work data 600, for example, using the method shown in FIG. 7. In step S131, the work data setting unit 164 selects one field 400 from the target fields 400. For example, in the example shown in FIG. 5, the work data setting unit 164 selects the second field 400-2.

In step S132 shown in FIG. 7, the work data setting unit 164 determines, from the integrated work data 600, an integrated small area 610 for setting the amount of work for the work data 300. For example, the work data setting unit 164 determines an integrated small area 610 that corresponds to a small area 510 included in the work data 300. The determined integrated small area 610 represents the integrated small area 610 for setting the amount of work for the corresponding small area 510.

First, the work data setting unit 164 determines whether the reference position 520 of the work data 300 overlaps with the intersection 630 of the first integrated line segment 611 and the second integrated line segment 612 of the integrated work data 600, as shown in FIG. 8. When the reference position 520 of the work data 300 does not overlap with the intersection 630 of the integrated work data 600, the work data setting unit 164 moves the area of the work data 300 so that the reference position 520 overlaps with the intersection 630 of the integrated work data 600. For example, the work data setting unit 164 selects the first integrated line segment 611, which is in the first direction from the reference position 520 and closest to the reference position 520, and the second integrated line segment 612, which is in the second direction from the reference position 520 and closest to the reference position 520. The area represented by the work data 300 is moved so that the reference position 520 overlaps with the intersection 630 between the selected first integrated line segment 611 and the second integrated line segment 612.

Here, the first integrated distance 621 of the integrated small area 610 represents the minimum value of the first distance 521 in the small areas 510 of the multiple work data 300, and the second integrated distance 622 represents the minimum value of the second distance 522 in the small areas 510 of the multiple work data 300. Therefore, since the first integrated distance 621 is less than or equal to the first distance 521 and the second integrated distance 622 is less than or equal to the second distance 522, when the area of the work data 300 is moved, the small area 510 includes the integrated small area 610.

Next, the work data setting unit 164 determines the integrated small area 610 of the integrated work data 600 that corresponds to the small area 510 based on the position of the small area 510 of the work data 300 while the reference position 520 is superimposed on the intersection 630 of the integrated work data 600. For example, the work data setting unit 164 determines the integrated work data 600 included in the area represented by the small area 510 as the integrated small area 610 that corresponds to that small area 510.

Next, the work data setting unit 164 detects boundary small areas of the integrated small area 610 that are included in the area of the work data 300 before the movement and are not included in the area of the work data 300 after the movement. For example, as shown in FIG. 9, by moving the area of the work data 300, the upper end line segment 512-1 of the work data 300 overlaps with one first integrated line segment 612-1, and the right end line segment 511-1 overlaps with one second integrated line segment 611-1. In this case, before the movement of the work data 300, the first integrated small area 610-1, the second integrated small area 610-2, the third integrated small area 610-3, the fourth integrated small area 610-4, and the seventh integrated small area 610-7 are included in the area. However, by moving the work data 300, these integrated small areas 610 are no longer included in the area of the work data 300. Therefore, the boundary subregion includes the first integrated subregion 610-1, the second integrated subregion 610-2, the third integrated subregion 610-3, the fourth integrated subregion 610-4, and the seventh integrated subregion 610-7.

Finally, the work data setting unit 164 determines the small area 510 corresponding to the boundary small area that was included in the area of the work data 300 before the movement and is not included in the area of the work data 300 after the movement. For example, the work data setting unit 164 determines the small area 510 corresponding to the integrated small area 610 adjacent to the boundary small area as the small area 510 corresponding to that boundary small area. For example, in the example shown in FIG. 9, the small area 510 corresponding to the first integrated small area 610-1 is determined to be the small area 510 corresponding to the fifth integrated small area 610-5. The small area 510 corresponding to the second integrated small area 610-2 is determined to be the small area 510 corresponding to the fifth integrated small area 610-5. The small area 510 corresponding to the third integrated small area 610-3 is determined to be the small area 510 corresponding to the sixth integrated small area 610-6. The small region 510 corresponding to the fourth integrated small region 610-4 is determined to be the small region 510 corresponding to the fifth integrated small region 610-5. The small region 510 corresponding to the seventh integrated small region 610-7 is determined to be the small region 510 corresponding to the eighth integrated small region 610-8.

In step S133 shown in FIG. 7, the work data setting unit 164 detects an integrated small area 610 that includes the areas of two or more fields 400. For example, as shown in FIG. 10, the work data setting unit 164 detects a ninth integrated small area 610-9 that includes a first area 401 included in a first field 400-1 and a second area 402 included in a second field 400-2. The amount of work for an integrated small area 610 that includes the areas of two or more fields 400 (hereinafter also referred to as an overlapping small area) is set based on the work data 300 of the multiple fields 400 included in the integrated small area 610.

In step S134 shown in FIG. 7, the work data setting unit 164 sets the amount of work for the integrated small area 610 based on the amount of work set for the small area 510. Except for integrated small areas 610 that include the areas of two or more fields 400, the work amount set for the small area 510 is set as the amount of work for the integrated small area 610 corresponding to that small area 510. For example, as shown in FIG. 8, the work data setting unit 164 moves the area of the work data 300 to set the amount of work for the small area 510 as the amount of work for the corresponding integrated small area 610.

In the example shown in FIG. 9, the small area 510 corresponding to the first integrated small area 610-1 is the small area 510 corresponding to the fifth integrated small area 610-5. Therefore, the amount of work of the small area 510 corresponding to the fifth integrated small area 610-5 is set as the amount of work of the first integrated small area 610-1. Similarly, the amount of work of the small area 510 corresponding to the fifth integrated small area 610-5 is set as the amount of work of the second integrated small area 610-2. The amount of work of the small area 510 corresponding to the sixth integrated small area 610-6 is set as the amount of work of the third integrated small area 610-3. The amount of work of the small area 510 corresponding to the fifth integrated small area 610-5 is set as the amount of work of the fourth integrated small area 610-4. The amount of work of the small area 510 corresponding to the eighth integrated small area 610-8 is set as the amount of work of the seventh integrated small area 610-7.

Therefore, the amount of work to be set for the adjacent integrated small area 610 is set as the amount of work for the boundary small area that is included in the area of the work data 300 before the movement and is not included in the area of the work data 300 after the movement. The amount of work to be set for the adjacent fifth integrated small area 610-5 is set as the amount of work for the first integrated small area 610-1. The amount of work to be set for the adjacent fifth integrated small area 610-5 is set as the amount of work for the second integrated small area 610-2. The amount of work to be set for the adjacent sixth integrated small area 610-6 is set as the amount of work for the third integrated small area 610-3. The amount of work to be set for the adjacent fifth integrated small area 610-5 is set as the amount of work for the fourth integrated small area 610-4. The amount of work to be set for the adjacent fifth integrated small area 610-8 is set as the amount of work for the seventh integrated small area 610-7.

As shown in FIG. 10, the amount of work for an overlapping sub-area that includes the areas of two or more fields 400, for example the ninth integrated sub-area 610-9, is set based on the amount of work set for the sub-area 510 of the work data 300 that corresponds to the two or more fields 400. For example, the amount of work for the overlapping sub-area is set based on the ratio of the area of the field 400 included in the overlapping sub-area and the amount of work for the corresponding sub-area 510. For example, the amount of work for the overlapping sub-area is calculated by multiplying the ratio of the area of the field 400 included in the overlapping sub-area and the amount of work for the sub-area 510 of the work data 300 that corresponds to the field 400, and adding up the amount of work thus multiplied. In this way, as shown in FIG. 10, when there is an area between the first field 400-1 and the second field 400-2 that is not included in the field 400, the area of this area does not need to be used to calculate the amount of work.

In the example shown in FIG. 10, the amount of work for the ninth integrated small area 610-9 is determined based on the ratio between the area of the first area 401 and the area of the second area 402, the amount of work for the work data 300 for the first field 400-1, and the amount of work for the work data 300 for the second field 400-2. Here, the small area 510 of the work data 300 for the first field 400-1 corresponding to the ninth integrated small area 610-9 is called the first small area. Also, the small area 510 of the work data 300 for the second field 400-2 corresponding to the ninth integrated small area 610-9 is called the second small area. For example, when the area of the first area 401 is equal to the area of the second area 402, the amount of work for the ninth integrated small area 610-9 is set to the average value of the amount of work for the first small area and the amount of work for the second small area. Furthermore, when the area of the first region 401 is twice the area of the second region 402, the workload of the ninth integrated small region 610-9 is set to ⅔ of the workload of the first small region plus ⅓ of the workload of the second small region.

In step S135 shown in FIG. 7, the work data setting unit 164 determines whether all of the target fields 400 have been selected. If there are unselected fields 400 among the target fields 400, the work data setting unit 164 returns to the process of step S131, selects an unselected field 400, and repeats the process. When all of the fields 400 have been selected, the generation of the integrated work data 600 ends, and the process proceeds to step S140 shown in FIG. 6.

In step S140 shown in FIG. 6, the output unit 170 outputs the generated integrated work data 600 to the terminal 200.

In step S150, the setting unit 250 of the terminal 200 acquires the integrated work data 600 from the output unit 170 of the data management device 100. The setting unit 250 may display an image representing the field 400 corresponding to the acquired integrated work data 600 on the input/output device 210. For example, the setting unit 250 displays an image showing the field 400 corresponding to the acquired integrated work data 600 on a map.

The acquired integrated work data 600 is registered in the work device 30 and used when the work device 30 works in multiple fields 400, for example, the first field 400-1, the second field 400-2, the third field 400-3, and the fourth field 400-4 shown in FIG. 3. For example, the integrated work data 600 is recorded from the terminal 200 to an external storage device, such as a USB (Universal Serial Bus) memory, and registered in the work device 30.

In this way, since the integrated work data 600 includes the amount of work in multiple fields 400, for example the amount of fertilizer applied, the worker can perform work in multiple fields 400 by registering the integrated work data 600 once in the work device 30. The data management system 1000 reduces the workload of the worker in the fields 400.

(Modification)
The configuration described in the embodiment is an example, and the configuration can be changed as long as the function is not impaired. Although an example in which the first direction and the second direction are perpendicular to each other is shown in Figures 2 and 5, the present invention is not limited to this. The angle between the first direction and the second direction may be an acute angle or an obtuse angle so that the first line segment 511 extending in the first direction and the second line segment 512 extending in the second direction intersect.

In one piece of work data 300, the first distance 521 of the small area 510 shown in FIG. 2 may be different from the first distance 521 of at least one other small area 510. In addition, in one piece of work data 300, the second distance 522 of the small area 510 may be different from the second distance 522 of at least one other small area 510. In one piece of integrated work data 600, the first integrated distance 621 of the integrated small area 610 shown in FIG. 5 may be different from the first integrated distance 621 of at least one other integrated small area 610. In addition, in one piece of integrated work data 600, the second integrated distance 622 of the integrated small area 610 may be different from the second integrated distance 622 of at least one other integrated small area 610.

The reference position 520 of the work data 300 shown in FIG. 2 may be set to any position as long as it can represent the position of the area of the work data 300. For example, the reference position 520 may represent any one of the intersections of the first line segment 511 and the second line segment 512 shown in FIG. 2. The reference position 520 may also represent a position representing the edge of the area of the work data 300 in the first direction, for example, the position closest to the first direction, or the position closest to the first direction. The reference position 520 may also represent a position representing the edge of the area of the work data 300 in the second direction, for example, the position closest to the second direction, or the position closest to the second direction.

Furthermore, the reference position 520 does not have to represent the position of the intersection between the first line segment 511 and the second line segment 512. For example, the reference position 520 may represent the position of the geometric center of the area of the work data 300.

The integration reference position 620 of the integrated work data 600 shown in FIG. 5 may be set to any position as long as it can represent the position of the area of the integrated work data 600, similar to the reference position 520 of the work data 300. For example, the integration reference position 620 may represent any one of the intersections of the first integration line segment 611 and the second integration line segment 612 shown in FIG. 5. The integration reference position 620 may represent the position of the edge of the area of the integrated work data 600 in the first direction. The integration reference position 620 may represent the position of the edge of the area of the integrated work data 600 in the second direction. The integration reference position 620 does not have to represent the position of the intersection of the first integration line segment 611 and the second integration line segment 612.

For example, in step S120 of FIG. 6, the data area determination unit 162 may determine the intersection of the second integrated line segment 612 passing through the end point in the first direction of the selected field 400 and the first integrated line segment 611 passing through the end point in the second direction as the integrated reference position 620. In this case, the integrated reference position 620 represents the position of the end of the area of the integrated work data 600 in both the first direction and the second direction. For example, the integrated reference position 620 represents the position in the area of the integrated work data 600 that is closest to the first direction and closest to the second direction. The integrated reference position 620 may also represent the position in the area of the integrated work data 600 that is closest to the first direction and closest to the second direction. The integrated reference position 620 may also represent the position in the area of the integrated work data 600 that is closest to the first direction and closest to the second direction. The integrated reference position 620 may represent a position in the area of the integrated task data 600 that is the furthest from the first direction and the furthest from the second direction.

In step S120 of FIG. 6, the data area determination unit 162 may determine the first integrated distance 621 and the second integrated distance 622 shown in FIG. 5 to be any length. For example, in the multiple work data 300 corresponding to the selected field 400, the maximum value of the first distances 521 of the small areas 510 may be determined as the first integrated distance 621. Also, the average value of the first distances 521 of the small areas 510 may be determined as the first integrated distance 621.

In step S132 shown in FIG. 7, the work data setting unit 164 determines whether the reference position 520 of the work data 300 overlaps with the intersection 630 of the integrated work data 600 as shown in FIG. 8, but is not limited to this. The work data setting unit 164 may also determine whether one of the intersections between the first line segment 511 and the second line segment 512 of the work data 300 overlaps with the intersection 630 of the integrated work data 600.

For example, the work data setting unit 164 may determine whether an intersection located at the end in both the first direction and the second direction among the intersections of the first line segment 511 and the second line segment 512 overlaps with the intersection 630 of the integrated work data 600. For example, the work data setting unit 164 may determine whether an intersection located most in the first direction and most in the second direction among the intersections of the first line segment 511 and the second line segment 512 overlaps with the intersection 630 of the integrated work data 600. The work data setting unit 164 may also determine whether an intersection located most in the opposite direction to the first direction and most in the second direction overlaps with the intersection 630 of the integrated work data 600. The work data setting unit 164 may also determine whether an intersection located most in the first direction and most in the opposite direction to the second direction overlaps with the intersection 630 of the integrated work data 600. The work data setting unit 164 may also determine whether the intersection point that is the furthest from the first direction and the furthest from the second direction overlaps with the intersection point 630 of the integrated work data 600.

In addition, in step S132 shown in FIG. 7, the work data setting unit 164 may move the area of the work data 300 so that the reference position 520 shown in FIG. 8 overlaps with one of the vertices of the integrated small area 610 that includes the reference position 520. Here, the vertices of the integrated small area 610 represent the intersections of the two first integrated line segments 611 and the two second integrated line segments 612 that surround the integrated small area 610. For example, the work data setting unit 164 may move the area of the work data 300 so that the reference position 520 overlaps with the closest vertex of the integrated small area 610 that includes the reference position 520.

7, when one integrated small area 610 of the integrated work data 600 includes multiple small areas 510 of the work data 300, the work data setting unit 164 may set the amount of work for the integrated small area 610 based on the amount of work for the multiple small areas 510 included in the integrated small area 610. For example, the work data setting unit 164 may set the minimum value of the amount of work for the multiple small areas 510 as the amount of work for the integrated small area 610. The amount of work for the integrated small area 610 may also be set to a statistical value, such as a maximum value or average value, of the amount of work for the multiple small areas 510.

The work data setting unit 164 may set the amount of work for the integrated small area 610 based on the amount of work for the multiple small areas 510 included in the integrated small area 610 and the ratio of the areas of the small areas 510. For example, the amount of work for the integrated small area 610 may be calculated by multiplying the ratio of the areas of the small areas 510 included in the integrated small area 610 and the amount of work for the small areas 510, and adding up the integrated amounts of work.

7, the work amount may be set only for the boundary small area shown in FIG. 9, specifically, for the integrated small area 610 included in the area of the field 400 among the integrated small areas 610 that are included in the area of the work data 300 before the movement and are not included in the area of the work data 300 after the movement. For example, in the example shown in FIG. 9, the first integrated small area 610-1, the second integrated small area 610-2, and the third integrated small area 610-3 do not include the area of the field 400, and the fourth integrated small area 610-4 and the seventh integrated small area 610-7 include the area of the field 400. In this case, the work amount set for the small area 510 of the work data 300 is not set for the first integrated small area 610-1, the second integrated small area 610-2, and the third integrated small area 610-3. The fourth integrated small area 610-4 is set with the amount of work set in the small area 510 corresponding to the fifth integrated small area 610-5, and the seventh integrated small area 610-7 is set with the amount of work set in the small area 510 corresponding to the eighth integrated small area 610-8.

In addition, in step S134 shown in FIG. 7, the amount of work may be set for the overlapping small area shown in FIG. 10, specifically the ninth integrated small area 610-9 including the areas of multiple fields 400, regardless of the area of the fields 400 included in the overlapping small area. For example, the work data setting unit 164 may acquire the amount of work for the small area 510 corresponding to the overlapping small area in the work data 300 corresponding to the multiple fields 400, and set the statistical value of the acquired amount of work, such as a minimum value, a maximum value, or an average value, as the amount of work for the overlapping small area. For example, even if the minimum value of the acquired amount of work is set, the worker may spray additional materials, such as fertilizers or pesticides, that are in short supply after the work by the work device 30 is completed.

After processing step S130 shown in FIG. 6, the work data setting unit 164 may set a value indicating that no work is being performed, for example 0, as the amount of work for the integrated small area 610 that does not include the area of the field 400. Also, the minimum value that the work device 30 can perform may be set as the amount of work for the integrated small area 610 that does not include the area of the field 400. Also, the minimum value of the amounts of work set in the integrated work data 600 may be set as the amount of work for the integrated small area 610 that does not include the area of the field 400.

The above-described embodiments and modifications are merely examples, and the configurations described in each embodiment and modification may be modified and/or combined as desired without impairing the functions. Furthermore, some of the functions described in the embodiments and modifications may be omitted as long as the required functions can be realized. For example, the data management system 1000 shown in FIG. 1 does not need to include the terminal 200. The terminal 200 may be incorporated in the operation device 30. Furthermore, all or part of the processing of the data management device 100 may be executed by the terminal 200. Furthermore, all or part of the processing of the terminal 200 may be executed by the data management device 100. Furthermore, the data management program 310 may include a setting program 320.
