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

The work device 30 includes a positioning device, for example, a GNSS (Global Navigation Satellite System) receiver, and acquires position information 560 representing the position at each time, as shown in FIG. Therefore, the position information 560 represents the position along the trajectory 550 along which the work device 30 has moved. Further, since the positioning device acquires the position information 560 at predetermined time intervals, two pieces of temporally adjacent position information 560 represent positions separated from each other by a distance 561. The work device 30 acquires position information 560 at each time when it moves in the field and performs work.

The work device 30 transmits operation information including position information 560 to the area management device 100. The area management device 100 acquires operational information in the field 500 from the working device 30, and calculates the working area and evaluation information, such as the amount of planting, the amount of pesticide sprayed, the yield, etc., based on the acquired operational information. . The evaluation information is calculated for a plurality of positions represented by the position information 560 acquired by the work device 30, for example. Therefore, the evaluation information is calculated corresponding to a position separated by a distance of 561.

The evaluation information may be displayed in correspondence with rectangular sections 510 into which the field 500 is divided in order to analyze cultivation management in units of regions into which the field 500 is divided. Here, if the section length 511 representing the length of one side of the section 510 is small, there may be a section 510 that does not include the position information 560. Evaluation information, for example, yield, in section 510 that does not include position information 560 is displayed as "0". Therefore, if the plot length 511 is small relative to the distance 561 of the position information 560, even if the evaluation information is displayed in correspondence with the plot 510, the user will not be able to grasp the evaluation information for each area into which the field 500 is divided. Hateful.

Therefore, the area management system 1000 sets the section length 511 according to the distance 561 between two adjacent pieces of position information 560. Thereby, the area management system 1000 reduces the occurrence of sections 510 that do not include location information 560. Therefore, the user can easily grasp the evaluation information for each area into which the field 500 is divided, and can efficiently analyze cultivation management.

It includes information representing ON/OFF status, position information 560 of the work device 30 at each time, work period, etc. When the working device 30 is a vehicle that pulls a working machine, such as a tractor, the operation information includes the PTO (power take-off) rotation speed when transmitting power to the working machine, the hitch height indicating the attitude of the working machine, and the like. Information such as lift arm angle may also be included. The work device 30 may be a vehicle integrally formed with a work machine, such as a combine harvester.

The display unit 250 acquires evaluation information from the area management device 100 and displays the acquired evaluation information.

(Area management system operation)
When the work device 30 shown in FIG. 1 performs work in the field 500, it transmits operation information to the calculation device 120 of the area management device 100. For example, when the engine is stopped, the work device 30 transmits operation information from when the engine is started to when the engine is stopped to the arithmetic unit 120 of the area management device 100. Upon receiving the operation information of the working device 30, the computing device 120 reads and executes the area management program 310. When the area management program 310 is read and executed, the arithmetic device 120 starts the process shown in FIG. 4, which is part of the area management method.

In step S110, the data storage unit 150 implemented by the arithmetic device 120 acquires operating information of the work device 30. Furthermore, the data storage unit 150 extracts position information 560 from the acquired operating information. Further, the data storage unit 150 calculates evaluation information for the plurality of positions represented by the position information 560 based on the acquired operation information. The calculated evaluation information is stored in the field data 300.

In step S120, the section determining unit 160 determines the direction in which the sections 510 are arranged. For example, the direction in which the sections 510 are arranged is acquired from the terminal 200. The arithmetic device 220 of the terminal 200 reads and executes the display program 320 in response to an operation for displaying the evaluation information stored in the field data 300. The display unit 250 implemented by the arithmetic device 220 acquires the direction in which the sections 510 are arranged, which is input by the user to the input/output device 210. For example, as shown in FIG. 5, the direction in which the sections 510 are arranged represents a first direction 512. Further, the direction in which the sections 510 are arranged may represent a second direction 513 orthogonal to the first direction 512. The display section 250 of the terminal 200 transmits information indicating the direction in which the sections 510 are arranged to the section determining section 160 of the area management device 100. Note that the direction in which the sections 510 are arranged may be determined in advance, and may be determined, for example, in a direction parallel to latitude lines or longitude lines. The direction in which the sections 510 are arranged represents the direction in which any one of the sides forming the outline (outline) of the sections 510 extends.

In step S130 shown in FIG. 4, the section determining unit 160 determines the size of the section 510 based on the position information 560 of the work device 30. For example, as shown in FIG. 5, the partition determining unit 160 determines whether the area is between two positions represented by two pieces of temporally adjacent position information 560, for example, first position information 560-1 and second position information 560-2. The size of the partition 510 is determined based on the distance 561 of . Here, two pieces of temporally adjacent position information 560 are referred to as adjacent position information, two positions represented by the adjacent position information are referred to as adjacent positions, and a distance 561 between the two adjacent positions is referred to as adjacent distance.

First, the section determining unit 160 extracts position information 560 corresponding to the linear trajectory 551 along which the working device 30 linearly moved. A trajectory 550 when the working device 30 performs work in the field 500 includes a linear trajectory 551 that moves linearly to perform the work, and a turning trajectory 552 that reverses the direction of movement. For example, the section determining unit 160 determines that the positions represented by three pieces of adjacent position information 560, for example, first position information 560-1, second position information 560-2, and third position information 560-3, are arranged in a straight line. Determine whether they are lined up. The section determining unit 160 connects a first straight line connecting a position represented by first position information 560-1 and a position represented by second position information 560-2, a position represented by second position information 560-2, and third position information. A second straight line connecting the position indicated by 560-3 is calculated. When the difference between the angle formed by the first straight line and the second straight line and 180 degrees is smaller than the threshold, the partition determining unit 160 selects the first position information 560-1, the second position information 560-2, and the third position. It is determined that the information 560-3 corresponds to the straight trajectory 551. The section determining unit 160 extracts the position information 560 corresponding to the straight trajectory 551 from among the acquired position information 560 by determining whether each piece of position information 560 corresponds to the straight trajectory 551.

Next, the section determining unit 160 calculates a distance 561 between two adjacent positions represented by two pieces of adjacent position information in the position information 560 corresponding to the straight trajectory 551. For example, the section determining unit 160 extracts first position information 560-1 and second position information 560-2 as two pieces of temporally adjacent position information. The division determining unit 160 calculates a distance 561 from the position represented by the extracted first position information 560-1 to the position represented by the second position information 560-2. This distance 561 is calculated for each combination of two pieces of temporally adjacent position information 560 corresponding to the straight trajectory 551.

Next, the partition determining unit 160 determines the combination of adjacent position information having the longest distance 561 among the combinations of adjacent position information for which the distances 561 have been calculated, and based on the distance 561 of the determined combination, the partition length 511 Calculate the minimum value of For example, the section determination unit 160 calculates the length of the distance 561 in the direction in which the sections 510 are arranged, for example, the first direction 512, for example, the first distance 562, as the minimum value of the section length 511. In this case, a combination of two pieces of adjacent position information having the longest distance 561 is determined from the combination of adjacent position information. The partition determining unit 160 calculates a first distance 562 representing the length of the distance 561 in the first direction 512 for the two determined adjacent position information. The calculated first distance 562 is calculated as the minimum value of the section length 511.

Next, the section determining section 160 transmits minimum value information representing the minimum value of the calculated section length 511 to the display section 250 of the terminal 200, and based on the section length 511 expressed in the response from the terminal 200, Determine the size of section 510. For example, the section determining section 160 transmits minimum value information representing the minimum value of the calculated section length 511 to the display section 250 of the terminal 200 as a section length request signal. The display section 250 displays a plurality of values larger than the minimum value of the section length 511 on the input/output device 210 based on the section length request signal. For example, the display unit 250 displays a plurality of values set as the length of one side of the section 510, for example, 10 m, 5 m, 3 m, and 1 m. Among the plurality of displayed values, the display unit 250 displays values that are greater than or equal to the minimum value of the section length 511 in a selectable manner, and displays values that are smaller than the minimum value of the section length 511 as unselectable. For example, when the minimum value of the section length 511 is 2 m, the display unit 250 displays 10 m, 5 m, and 3 m as selectable, and displays 1 m as unselectable. The user inputs an operation into the input/output device 210 to select the length of one side of the section 510 from a plurality of values selectably displayed on the input/output device 210 . The display unit 250 transmits information representing the length of the selected side to the partition determining unit 160 of the area management device 100. The section determining unit 160 determines the acquired length of one side as the length of one side of the section 510.

In step S140 shown in FIG. 4, the section determination unit 160 determines the positions of the plurality of sections 510 based on the length of one side of the sections 510. For example, first, the section determining unit 160 calculates a circumscribed rectangle 515 of the farm field 500, which is surrounded by two straight lines extending in the first direction 512 and two straight lines extending in the second direction 513. The circumscribed rectangle 515 includes a line segment extending in the first direction 512 and a line segment extending in the second direction 513 in its outline, and represents the smallest rectangle surrounding the farm field 500.

Next, the section determining unit 160 determines one vertex of the circumscribed rectangle 515 as the reference point 516. The reference point 516 is, for example, the southwest vertex of the circumscribed rectangle 515.

Finally, the section determination unit 160 determines the positions of the plurality of sections 510 based on the reference point 516. The section determining unit 160 determines the position of one section 510 as a reference so that the reference point 516 represents one vertex of one section 510 among the plurality of sections 510. The section determining unit 160 determines the positions of the plurality of sections 510 so that the sections 510 are lined up in the first direction 512 and the second direction 513 from the determined position of the section 510.

For example, the section determination unit 160 determines the outlines of the plurality of sections 510 based on the reference points 516. Specifically, the section determining unit 160 determines a first parallel straight line that passes through the reference point 516 and extends in the first direction 512. The section determining unit 160 determines a plurality of parallel straight lines that are parallel to the determined first parallel straight line and such that the distance between adjacent parallel straight lines is the calculated section length 511. Further, the section determining unit 160 determines a first orthogonal straight line that passes through the reference point 516 and extends in the second direction 513. The section determining unit 160 determines a plurality of orthogonal straight lines that are parallel to the first orthogonal straight line and such that the distance between adjacent orthogonal straight lines is the calculated section length 511. The section determining unit 160 determines a plurality of regions surrounded by a plurality of determined parallel straight lines and a plurality of orthogonal straight lines as a plurality of sections 510.

In step S150 shown in FIG. 4, the output unit 170 calculates evaluation information for the determined section 510, and outputs the calculated evaluation information to the display unit 250 of the terminal 200. For example, the output unit 170 acquires evaluation information included in each of the determined sections 510 based on the field data 300. Specifically, the output unit 170 extracts the position information 560 included in the determined section 510 from the field data 300, and acquires the evaluation information associated with the extracted position information 560. The output unit 170 calculates evaluation information for the section 510 using the acquired evaluation information. For example, when the evaluation information is a value for comparing the total yield for each section 510, the output unit 170 outputs the total yield associated with the position information 560 included in the section 510, Calculate the evaluation information by dividing by the number of . Further, when the evaluation information is the yield per unit area, the output unit 170 divides the calculated total yield by the area of the field 500 included in the section 510 to calculate the evaluation information. The output unit 170 generates an output signal representing the calculated evaluation information in association with the section 510. The generated output signal is output from the communication device 130 of the area management device 100 to the display unit 250 of the terminal 200.

In step S160, the display unit 250 of the terminal 200 displays evaluation information based on the output signal. The display section 250 displays evaluation information for the section 510 determined by the section determining section 160, as shown in FIG. The evaluation information is displayed in a distinguishable manner according to the value represented by the evaluation information, such as the yield and the amount of pesticide sprayed. For example, the evaluation information is displayed in different colors depending on the value it represents. Further, the evaluation information may be distinguished depending on the type of hatching.

In this way, the area management system 1000 supports the user's analysis of cultivation management by determining the size of the section 510 based on the position information 560 of the working device 30.

(Modified example)
The configuration described in the embodiment is an example, and the configuration can be changed within a range that does not impede functionality. For example, the section determining unit 160 may determine the length of one side of the section 510 using any method as long as the formation of sections 510 that do not include the position information 560 can be reduced. For example, the section determining unit 160 may determine the length of one side of the section 510 based on a first distance 562 in the first direction 512 and a second distance 563 in the second direction 513 regarding the distance 561. Specifically, the section determination unit 160 calculates a first distance 562 and a second distance 563 based on the distance 561. The section determining unit 160 determines the longer one of the first distance 562 and the second distance 563 as the minimum value of the section length 511.

Further, before determining the combination of position information 560, the section determining unit 160 may determine which of the first direction 512 and the second direction 513 to use as the minimum value of the section length 511. For example, the section determining unit 160 determines that the angle formed by the first direction 512 and the second direction 513 with a straight line connecting the position represented by the first position information 560-1 and the position represented by the second position information 560-2 is small. Determine direction. The division determination unit 160 calculates a distance representing the length of the distance 561 in the determined direction, for example, the first direction 512, for example, a first distance 562, for each combination of two pieces of temporally adjacent position information 560. Among the calculated first distances 562, the longest first distance 562 is determined as the minimum value of the section length 511.

Further, the section determining unit 160 may calculate the length of the distance 561 as the minimum value of the section length 511. In this case, the longest distance 561 among the distances 561 calculated for the combination of two pieces of temporally adjacent position information 560 is calculated as the minimum value of the section length 511.

In this way, the partition determining unit 160 determines the maximum value of the length representing the distance between two adjacent positions represented by two temporally adjacent adjacent position information, such as the distance 561, the first distance 562, and the second distance 563. may be determined as the minimum value of the section length 511.

In addition, the division determining unit 160 divides lengths representing distances between two adjacent positions represented by two temporally adjacent adjacent position information, such as the average value of distance 561, first distance 562, second distance 563, etc. It may be determined as the minimum value of the length 511.

The length of the section 510 in the first direction 512 may be different from the length in the second direction 513. For example, in step S130 shown in FIG. 4, the user selects the length of the section 510 in the first direction 512 and in the second direction 513, respectively. The section determining section 160 obtains the selected length from the display section 250 of the terminal 200 and determines the size of the section 510.

Further, the minimum length of the section 510 in the first direction 512 may be different from the minimum length of the second direction 513. For example, in step S130 shown in FIG. 4, the section determining unit 160 calculates a first distance 562 in the first direction 512 and a second distance 563 in the second direction 513 from the position information 560. The section determining unit 160 determines the maximum value of the calculated first distance 562 as the minimum value of the length of the section 510 in the first direction 512. Furthermore, the section determining unit 160 determines the maximum value of the calculated second distance 563 as the minimum value of the length of the second direction 513 in the section 510.

Furthermore, the section determining unit 160 may determine the minimum value of the length of one side of the section 510 based on the position of the straight trajectory 551 shown in FIG. 5. The section determining unit 160 calculates a linear trajectory distance representing the distance between two linear trajectories 551 adjacent to each other. Furthermore, the section determining unit 160 calculates the maximum value of the first distance 562 in the first direction 512 and the maximum value of the second distance 563 in the second direction 513 from the position information 560, respectively. When the maximum value of the first distance 562 is smaller than the linear trajectory distance, the section determining unit 160 may determine the linear trajectory distance as the minimum value of the length of the section 510 in the first direction 512. Further, when the maximum value of the second distance 563 is smaller than the linear trajectory distance, the section determining unit 160 may determine the linear trajectory distance as the minimum value of the length of the section 510 in the second direction 513.

The partition determining unit 160 may determine the reference point 516 using any method. For example, the section determining unit 160 may determine the geometric center of the circumscribed rectangle 515 as the reference point 516.

The evaluation information included in the field data 300 may be stored in any format as long as a value corresponding to the section 510 can be calculated.

The distance 561 between two pieces of temporally adjacent position information 560 shown in FIG. 5 may be calculated using position information 560 that is not included in the straight trajectory 551. For example, when the work device 30 performs work while turning, the section determination unit 160 may calculate the distance 561 using position information 560 that is not included in the straight trajectory 551. In this case, the section determination unit 160 calculates the distance 561 and determines the section length 511 without distinguishing between the straight trajectory 551 and the turning trajectory 552.

The partition determining unit 160 may determine the partition length 511 based on the value input by the user into the input/output device 210 of the terminal 200. For example, the section determining section 160 transmits minimum value information representing the minimum value of the calculated section length 511 to the display section 250 of the terminal 200 as a section length request signal. The display unit 250 displays the minimum value of the partition length 511 on the input/output device 210 based on the partition length request signal. The user inputs the length of one side of the section 510 to the input/output device 210 based on the minimum value of the section length 511 displayed on the input/output device 210 . The display unit 250 transmits the input information representing the length of one side to the partition determining unit 160 of the area management device 100. The section determining unit 160 determines the acquired length of one side as the length of one side of the section 510.
