Description

[Technical Field]

[0001] The present invention relates to a work management method, a work management system, and a work management program, and can be suitably used, for example, in a work management method, a work management system, and a work management program for managing agricultural work. [Background technology]

[0002] In farming, it is important to understand and evaluate the production status and productivity of fields that users manage or are involved in. However, in highly mechanized fields, even a single field involves numerous working machines, and the types of work these machines perform vary widely. Furthermore, the same tractor may be equipped with different working machines, performing different types of work, and planters and harvesters, which perform a single type of work, may perform the same work over multiple days. As such, field information can become complex, making it difficult to grasp every detail.

[0003] In relation to the above, Patent Document 1 (JP 2017-102924 A) discloses an agricultural management system. In this agricultural management system, a database server receives agricultural land information about the farmland where the crops have been harvested and operational information about the harvesting, and associates and records the information with the harvesting. The database server then displays the information on a terminal display in response to a user request.

[0004] Furthermore, Patent Document 2 (Japanese Patent No. 6302391) discloses a remote server that receives and manages information indicating the status of each agricultural machine from various agricultural machines. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-102924 [Patent Document 2] Patent No. 6302391 Summary of the Invention [Problem to be solved by the invention]

[0006] In each of the above technologies, the status of agricultural work performed by multiple agricultural machines is managed by a server for each field, making it easier for operators to grasp the progress of various agricultural work tasks for each field. However, when multiple types of agricultural machines or multiple agricultural machines of the same type are performing work simultaneously, or when multiple agricultural machines are performing work in the same field, the operating status of multiple agricultural machines in each field is included. In such cases, it is difficult to easily grasp the progress of agricultural work.

[0018] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A work management method, a work management system, and a work management program according to the present invention will be described below with reference to the accompanying drawings.

[0019] (First embodiment) As shown in FIG. 1, a work management system 1 according to one embodiment includes a work management device 5 and an external terminal 6. The work management device 5 receives positioning information transmitted by an on-board terminal 3 via a network 4.

[0025] 3, the external terminal 6 may be configured as a computer device such as a tablet terminal. The external terminal 6 includes a bus 60, an arithmetic unit 61, a storage device 62, a communication device 63, and an input / output device 64. The arithmetic unit 61, the storage device 62, the communication device 63, and the input / output device 64 are connected to each other via the bus 60 so as to be able to communicate with each other.

[0026] The arithmetic device 61 includes an input unit 611, a calculation unit 612, and an output unit 613. The input unit 611, the calculation unit 612, and the output unit 613 are each a virtual function unit that represents a function realized by the arithmetic device 61 executing a display operation program.

[0030] A work management method according to one embodiment will be described with reference to Fig. 4. Fig. 4 is a flowchart showing an example of the configuration of a work management program according to one embodiment. Below, an example of the operation of the work management system 1 that is realized by the work management device 5 executing the work management program in one embodiment will be described.

[0031] When the work management device 5 according to one embodiment is started, the arithmetic device 51 of the work management device 5 executes the work management program, and the work management method starts. When the work management method according to one embodiment starts, step S1 is executed.

[0032] In step S1, the input unit 511 of the calculation device 51 of the work management device 5 prepares area information. The area information represents operation information, work area information, and work type information in association with each other.

[0033] The operation information will now be described. The operation information includes positioning information obtained by measuring multiple positions that the work machine passed through while working in the field 9, and machine attribute information that indicates the machine attributes of the work machine. The operation information may be transmitted from an on-board terminal 3 mounted on the work vehicle 2 and received by the work management device 5.

[0034] The positioning information will now be described. The positioning information is obtained by measuring multiple positions passed through during work by the on-board terminal 3 mounted on the work vehicle 2. The positioning information includes, for example, the latitude and longitude of the position where the measurement was made, and the time when the measurement was made.

[0035] We will now explain machine attribute information and the machine attributes represented by the machine attribute information. Machine attributes are attributes that classify work machines according to the work they perform. Machine attributes include, for example, tractor, transplanter, pesticide sprayer, harvester, etc. If it is known that a tractor only performs specific work, for example, if a tractor is dedicated to transplanting or pesticide spraying, the machine attribute of the tractor may be set to transplanter or pesticide sprayer depending on the type of machine attached to the tractor. Information that represents machine attributes so that it can be handled by the work management device 5 is called machine attribute information.

[0036] The work type and work type information will now be described. The work type is the type of work performed to grow crops. Work types include, for example, subsoiling, plowing, leveling, transplanting, top dressing, inter-till weeding, pest control, and harvesting. Information that represents the work type in a manner that can be handled by the work management device 5 is called work type information. The work type information may be acquired by the calculation unit 512 of the arithmetic device 51 of the work management device 5 by estimation based on machine attribute information.

[0037] The work area and work area information will now be explained. The area of ​​the field 9 where the work machine has performed work is called the work area. Information that represents the work area so that it can be handled by the work management device 5 is called work area information. The work area information may be obtained by the calculation unit 512 of the arithmetic device 51 of the work management device 5 by estimating it based on the positioning information and the work width of the work machine. Here, the work width represents the width of the area where the work machine performed work on the field 9 while moving. The work area information also includes the date and time the work was performed, the machine's machine attribute information, and the type of work performed.

[0038] After step S1, step S2 is executed. In step S2, the output unit 515 of the calculation device 51 of the work management device 5 and the output unit 613 of the calculation device 61 of the external terminal 6 display the work area 91 based on default conditions. More specifically, first, the output unit 515 of the work management device 5 outputs work area information representing the work area that meets the default conditions and transmits it to the external terminal 6, and then the output unit 613 of the external terminal 6 displays the work area 91 represented by the received work area information. Here, first, how the work area 91 is displayed will be described with reference to FIG. 5. Note that a method for extracting the displayed work area 91 based on the default conditions will be described later.

[0039] 5, the touch panel device serving as the output device 642 outputs information representing a work area 91 extracted from a plurality of fields 9 based on predetermined conditions by displaying it on a map. At this time, the touch panel device displays the position and shape of the work area 91 on the map under the control of an output unit 613 implemented by the arithmetic unit 61 of the external terminal 6 executing a display operation program. The output unit 613 may also control the touch panel device to display a mark 92 indicating a representative position of the work area 91.

[0040] After step S2, step S3 is executed. In step S3, the input unit 511 of the work management device 5 determines whether the user has input extraction conditions for the work area 91. More specifically, when the user operates the touch panel device serving as the input device 641 of the external terminal 6 to make an input for setting or changing the extraction conditions for the work area 91, information representing this input is transmitted from the output unit 613 of the external terminal 6 to the input unit 511 of the work management device 5. The input unit 511 of the work management device 5 waits by repeating step S3 while the information representing this input is not received (No), and proceeds to step S4 when the information representing this input is received (Yes).

[0041] An example of a method in which a user operates a touch panel device to input extraction conditions for the work area 91 will be described. In addition to the work area 91 displayed on a map, the touch panel device serving as the output device 642 of the external terminal 6 may display condition setting windows 70 and 80 for inputting extraction conditions. The user may operate the touch panel to appropriately operate input frames 71, 72, and 73 and switches 81, 82, 83, 84, and 85 provided in the condition setting windows 70 and 80, thereby setting or changing the extraction conditions.

[0042] In the example of Fig. 5, the user may set conditions for extracting work area 91 by inputting a desired character string, a desired period, and a desired work type into input boxes 71, 72, and 73 included in condition setting window 70. Furthermore, by operating switches 81, 82, 83, 84, and 85 included in condition setting window 80, the user may switch between displaying or hiding registered fields, displaying or hiding work area 91 and mark 92, displaying or hiding work areas whose machine attribute is a harvester, displaying or hiding work areas whose machine attribute is a truck, displaying or hiding work areas whose machine attribute is a tractor, and displaying or hiding work areas whose machine attribute is a transplanter, respectively.

[0043] In step S4, the extraction unit 514 of the calculation device 51 of the work management device 5 extracts the work area 91 based on the extraction conditions input in step S3. Here, the extraction unit 514 references the area information to extract work type information that satisfies the extraction conditions input in step S3, and extracts work area information associated with the extracted work type information as extracted area information. Here, if there is a one-to-one correspondence between the work type selected as the extraction condition and the machine attribute corresponding to the selected work type, work area information associated with machine attribute information that represents this machine attribute may be extracted as extracted area information.

[0044] After step S4, step S5 is executed. In step S5, the output unit 515 of the calculation device 51 of the work management device 5 and the output unit 613 of the calculation device 61 of the external terminal 6 display the work area 91 based on the extraction conditions. More specifically, first, the output unit 515 of the work management device 5 outputs work area information representing the work area that meets the extraction conditions and transmits it to the external terminal 6, and then the output unit 613 of the external terminal 6 displays the work area 91 represented by the received work area information.

[0045] Referring to Figure 6, an example of the display of work area 91 extracted based on the extraction conditions entered in step S3 will be described. In the example of Figure 6, work area 91 in which a work machine with a machine attribute in which switch 83 is in the on state performed work of the work type entered in input box 73 during the period entered in input box 72 is displayed with a mark 92. More specifically, work area 91 in which a work machine with a machine attribute of a harvester corresponding to switch 83 performed work of the work type "harvesting" corresponding to input box 73 during the period from May 1, 2021 to May 7, 2021, entered in input box 72, is displayed with a mark 92. This display is obtained as a result of the user's input into input box 72, input box 73, and switch 83 in step S3.

[0046] After step S5, the process may return to step S3 and wait until new extraction conditions are input.

[0047] As described above, in the processing of steps S3 to S5, the user is required to input appropriate extraction conditions in order to display the desired work area 91. The more fields 9 that the user manages, the more complicated it may become to input extraction conditions. Therefore, in one embodiment, an attempt is made to estimate the work area 91 that the user desires at the time of step S2 and automatically display it.

[0048] Details of step S2 will be described with reference to Fig. 7. When step S2 is executed after step S1 in Fig. 4, step S201 in Fig. 7 is executed first.

[0049] In step S201, the input unit 511 of the calculation device 51 of the work management device 5 prepares cultivation calendar information representing a cultivation calendar. As shown in FIG. 2 , the cultivation calendar information is stored in the cultivation calendar information storage unit 524 of the storage device 52 of the work management device 5. The cultivation calendar information may be read from the recording medium 520 or may be obtained from outside via the communication device 53.

[0050] FIG. 8 is a table showing an example of the contents of a cultivation calendar according to one embodiment. Multiple periods are listed horizontally in the table in FIG. 8 . Here, "B" represents the beginning of each month, "M" represents the middle of each month, and "E" represents the end of each month. Furthermore, task types and task names representing the task types are listed vertically in the table in FIG. 8 . A check mark is placed in a cell where a period and a task type intersect if the task of that task type is scheduled to be performed during that period, and no check mark is placed if the task is not scheduled. The task name is a name unique to a producer or production area, and may be the same as the task type, or a different name may be used as long as it is linked to the task type. As an example, the task name "planting" may be used for a task whose task type is "transplanting."

[0051] The cultivation calendar may be entered or changed by the user. As an example, with the table shown in FIG. 8 displayed on a touch panel device serving as the output device 642 of the external terminal 6, the user can enter or delete check marks in cells where the period and task type intersect by operating the touch panel device serving as the input device 641 of the external terminal 6. The user can also add or delete a task type row by operating the "ADD" button or "DELETE" button. Furthermore, the user can change the task type of that row by operating the task type pull-down menu.

[0052] After step S201, step S202 is executed. In step S202, a user logs in, and the input unit 511 of the calculation device 51 of the work management device 5 acquires the login time. This login may occur when the user starts up the external terminal 6 and the external terminal 6 starts communication with the work management device 5.

[0053] After step S202, step S203 is executed. In step S203, the extraction unit 514 of the calculation device 51 of the work management device 5 reads out the content corresponding to the login time from the cultivation calendar. Here, the extraction unit 514 extracts, from the cultivation calendar information, the work type scheduled for the period including the login time when the user logged in. The extracted work type is called the extracted work type. In the example shown in FIG. 8, if the login time is included in early May 2021, data for period 101 is read out from the cultivation calendar information.

[0054] After step S203, step S204 is executed. In step S204, the determination unit 513 of the calculation device 51 of the work management device 5 determines whether there is one work type that corresponds to the content read out in step S104. If there is one work type that corresponds (Yes), step S204 is followed by step S205. Conversely, if there is not one work type that corresponds (No), step S204 is followed by step S207. In the example shown in FIG. 8, the work type included in the read data for period 101 is one type, "top dressing," so in this case step S204 is followed by step S205.

[0055] In step S205, the extraction unit 514 of the calculation device 51 of the work management device 5 extracts a work area where the work type corresponding to the content read out in step S203 is to be performed. More specifically, work area information representing the work area associated with the work type of interest is extracted. The extracted work area information is called extracted area information.

[0056] After step S205, step S206 is executed. In step S206, the output device 642 of the external terminal 6 displays the work area represented by the extraction area information extracted in step S205. More specifically, the output unit 515 of the work management device 5 controls the communication device 53 to transmit the extraction area information to the external terminal 6, and the output unit 613 of the calculation device 61 of the external terminal 6 controls the output device 642 to display the work area 91 represented by the extraction area information.

[0057] As an example, in step S206, the extracted work area 91 may be displayed as shown in Fig. 9. Fig. 9 is a diagram showing an example of a display according to one embodiment. At this time, a period including the login time may be displayed in input box 72 of condition setting window 70. Furthermore, the extracted work type may be displayed in input box 73 of condition setting window 70.

[0058] After step S206, the process proceeds to step S3 in FIG.

[0059] In step S207, the calculation unit 512 of the arithmetic device 51 of the work management device 5 counts the total number of work areas for each work type that exists within a predetermined period. More specifically, the calculation unit 512 calculates the total number of pieces of extracted area information associated with each of the multiple work types determined in step S204 to be more than one type. FIG. 10 is a table showing an example of the contents of a cultivation calendar according to one embodiment. In the example of FIG. 10, the work types included in the data for the read period 102 are "transplanting," "top dressing," and "intertillage weeding," so the total number of pieces of extracted area information associated with each of these three work types is calculated.

[0060] After step S207, step S208 is executed. In step S208, the extraction unit 514 of the calculation device 51 of the work management device 5 extracts the work area of ​​the work type with the largest total number tallied in step S207.

[0061] After step S208, step S209 is executed. In step S209, as in step S206, the output unit 613 of the external terminal 6 controls the output device 642 to display the registered field 9 and the work area extracted in step S208.

[0062] As an example, in step S209, the registered scattered fields 9 may be displayed as shown in FIG. 11A, and the extracted work areas may be displayed as shown in FIG. 11B. FIG. 11A is a diagram illustrating an example of a display according to an embodiment. FIG. 11B is a diagram illustrating an enlarged view of a portion 93 of FIG. 11A. In this case, a condition setting window 70 may be displayed in FIG. 11A along with the field 9, and a period including the login time may be displayed in the input frame 72 of the condition setting window 70. Furthermore, all of the extracted work types may be displayed in the input frame 73 of the condition setting window 70. In the example of FIG. 11A, the three types of work types read in FIG. 10, namely, "transplanting," "top dressing," and "intertillage weeding," are displayed in the input frame 73. As an example, when multiple work types are extracted, the order of displaying these multiple work types in the input frame 73 may be in descending order of the total number of work areas for that work type. In the example of FIG. 11A, "transplanting," which has the largest number of corresponding work areas, is displayed at the top of the input frame 73 and highlighted in bold.

[0063] In the example of FIG. 11B, fields 9A, 9B, 9C, 9D, 9E, and 9F are displayed in a portion 93 of FIG. 11A. The example of FIG. 11B also shows that the "transplanting" work area 9A1, which has the largest total number of corresponding work areas, is located inside field 9A. Similarly, the example of FIG. 11B also shows that the "transplanting" work areas 9D1 and 9D2 are located inside field 9D. Regarding the "top dressing" work areas 9B1 and 9B2 displayed in input frame 73 of FIG. 11A, their location inside field 9B may or may not be indicated. However, if indicated, it is preferable to highlight the "transplanting" work areas 9A1, 9D1, and 9D2. Similarly, for the "inter-tillage weeding" work area 9C1 displayed in input frame 73 in Figure 11A, it may or may not be necessary to indicate that it is located inside field 9C. However, if it is indicated, the "transplanting" work areas 9A1, 9D1, and 9D2 are displayed with greater emphasis. However, in either case, it is preferable to always display the frame lines representing fields 9A, 9B, 9C, 9D, 9E, and 9F.

[0064] FIG. 11C shows the display of FIG. 11B in a different state. This state is entered when the user selects one of the work types displayed in the input frame 73 shown in FIG. 11A by operating the external terminal 6, for example. The example in FIG. 11C shows a state in which "top-dressing" is selected from the work types displayed in the input frame 73 shown in FIG. 11A. In this case, "top-dressing" is displayed in bold in the input frame 73, and FIG. 11C shows that the "top-dressing" work areas 9B1 and 9B2 are located inside the field 9B. The remaining "transplanting" work areas 9A1, 9D1, and 9D2 and the "inter-tillage weeding" work area 9C1 may or may not be displayed. However, if they are displayed, the "top-dressing" work areas 9B1 and 9B2 selected in the input frame 73 are displayed with greater emphasis. In either case, however, it is preferable to always display the borders representing the fields 9A, 9B, 9C, 9D, 9E, and 9F.

[0065] After step S209, the process proceeds to step S3 in FIG.

[0066] (Variation) A modified example of the work management method according to one embodiment will be described with reference to Fig. 12. The work management method according to this modified example can be obtained by replacing step S4 shown in Fig. 4 with the flowchart shown in Fig. 12. In this modified example, when step S4 shown in Fig. 4 starts, step S401 shown in Fig. 12 starts.

[0067] In step S401, the determination unit 513 of the work management device 5 determines whether the extraction conditions include a period and do not include a work type and a machine attribute. If the determination result is true (TRUE), the process proceeds to step S402. Conversely, if the determination result is false (FALSE), the process proceeds to step S404.

[0068] In step S402, the calculation unit 512 of the work management device 5 counts the total number of work areas for each work type that exist within the target period that meets the extraction conditions. At this time, the work area for the work type with the largest total count is stored so that it can be distinguished from work areas for other work types. As an example, in the cultivation calendar shown in FIG. 13, the extraction conditions include a period 103 from early April 2021 to late May 2021, and the work types that exist within this period 103 are "transplanting," "top dressing," and "intertillage weeding."

[0069] After step S402, step S403 is executed. In step S403, the extraction unit 514 of the work management apparatus 5 extracts work areas for all work types that exist within the target period that meets the extraction conditions. As an example, in the example shown in FIG. 13, the work areas for "transplanting," "top dressing," and "inter-tillage weeding" are extracted.

[0070] After step S403, the process proceeds to step S5 in FIG. 4. In step S5, the registered scattered fields 9 are displayed as shown in FIG. 14A, and the work areas extracted in step S403 are displayed as shown in FIG. 14B. FIG. 14A is a diagram showing an example of a display according to one embodiment. FIG. 14B is a diagram showing an enlarged view of a portion 93 of FIG. 14A. At this time, the work area for the work type with the largest total count tallied in step S402 is displayed highlighted so as to be distinguishable from the work areas for the other work types. As an example, the display example shown in FIG. 14B displays the work areas for "transplanting," "top dressing," and "intertillage weeding" extracted in step 403. More specifically, it shows that the "transplanting" work areas 9A1, 9D1, and 9D2 are located inside fields 9A and 9D, the "top-dressing" work areas 9B1 and 9B2 are located inside field 9B, and the "inter-tillage weeding" work area 9C1 is located inside field 9C. Furthermore, of these work areas, the "transplanting" work areas 9A1, 9D1, and 9D2, which have the largest total number, are highlighted so as to be distinguishable from the other work areas 9B1, 9B2, and 9C1. In the example of FIG. 14B, the work areas are highlighted using a thick line, but the present disclosure is not limited to this example, and other highlighting methods such as different colors or different line types may also be used.

[0071] In the state shown in FIG. 14B , the display identifying the task type corresponding to each work area may be omitted. Alternatively, the task type of a work area may be displayed using text or other means as a result of the user selecting the display of the work area. An example of such a display is shown in FIG. 14C . The example in FIG. 14C shows a state in which the word “top-fertilizing” appears in work areas 9B1 and 9B2 when the user selects the “top-fertilizing” work area 9B1 or 9B2 by touching the touch panel or other means. In this case, the previously displayed “transplanting” work areas 9A1, 9D1, and 9D2 and the “inter-tillage weeding” work area 9C1 may remain displayed or may not be displayed. However, if displayed, it is preferable to highlight the selected “top-fertilizing” work areas 9B1 and 9B2 so that they can be distinguished.

[0072] When performing these processes, the input box 73 may remain blank unless the user operates the input box 73. Conversely, the user may operate the input box 73 to search for a work area of ​​the specified work type. As a result, work areas that match the search conditions may be selectively displayed.

[0073] In step S404, the extraction unit 514 of the work management apparatus 5 extracts the work area of ​​the extracted work type. Here, the work area of ​​the extracted work type may be the work area of ​​all work types that meet the extraction conditions.

[0074] After step S404, the process proceeds to step S5 in Fig. 4. In step S5, all the work areas extracted in step S404 are displayed.

[0075] As described above, according to one embodiment, when a user operates the external terminal 6 to log in, the information the user needs is predicted and automatically displayed before the user sets the conditions for extracting the work area 91. As a result, the information the user needs can be output efficiently. After that, by the user appropriately setting the extraction conditions, other information desired by the user can also be output.

[0076] The invention made by the inventor has been specifically described above based on the embodiments, but it goes without saying that the present invention is not limited to the embodiments and can be modified in various ways without departing from the spirit of the invention. Furthermore, the features described in the embodiments can be freely combined within the scope of technical compatibility. [Explanation of symbols]
