Summary of the Invention

Problems to be Solved by the Invention

[0005] However, the working hours in a field vary depending on the working environment, such as weather, soil conditions, yield per unit area, etc. Therefore, the actual working hours often differ from the past work performance.

[0006] In view of the above situation, one of the objectives of the present disclosure is to present information representing more accurate working hours. Other objectives can be understood from the following description and the explanation of the embodiments.

Means for Solving the Problems

[0007] The means for solving the problem are described below using the numbers and symbols used in the embodiments for carrying out the invention. These numbers and symbols are added in parentheses for reference to show an example of the correspondence between the claims and the embodiments for carrying out the invention. Therefore, the claims should not be interpreted restrictively because of the parenthetical statements.

[0008] A work management method according to one embodiment for achieving the above objective includes determining the first work time required for the first work in the target field (500) based on the work performance of the first work performed in the past. The work management method also includes determining the area of ​​the work area (700) in the target field (500) where the first work was performed, based on the location information of the work device (30) performing the first work in the target field (500). The work management method also includes determining the second work time for the work device (30) to perform the first work in the target field (500) based on the work execution time for the first work performed by the work device (30) in the work area (700), the area of ​​the work area (700), and the area of ​​the target field (500). The work management method also includes outputting first display information representing the first work time before the first work by the work device (30) in the target field (500) begins. The work management method includes outputting second display information representing the second work time after the first work by the work device (30) has started in the target field (500).

[0009] A work management system (1000) according to one embodiment for achieving the above objective comprises a first time determination unit (150), a region determination unit (160), a second time determination unit (170), and an output unit (180). The first time determination unit (150) determines the first work time required for the first work in the target field (500) based on the work performance of the first work performed in the past. The region determination unit (160) determines the area of ​​the work region (700) in the target field (500) where the first work was performed, based on the position information of the work device (30) performing the first work in the target field (500). The second time determination unit (170) determines the second work time for the work device (30) to perform the first work in the target field (500) based on the work execution time for the first work performed by the work device (30) in the work area (700), the area of ​​the work area (700), and the area of ​​the target field (500). The output unit (180) outputs first display information representing the first work time before the first work by the work device (30) in the target field (500) begins. The output unit (180) also outputs second display information representing the second work time after the first work by the work device (30) in the target field (500) has begun.

[0010] A work management program (420) according to one embodiment for achieving the above objective causes the computing units (120, 220) to determine the first work time required for the first work in the target field (500) based on the work performance of the first work performed in the past. The work management program (420) also causes the computing units (120, 220) to determine the area of ​​the work area (700) in the target field (500) where the first work was performed, based on the position information of the work device (30) performing the first work in the target field (500). The work management program (420) causes the computing units (120, 220) to determine the second work time for the work device (30) to perform the first work in the target field (500), based on the work time during which the first work was performed by the work device (30) in the work area (700), the area of ​​the work area (700), and the area of ​​the target field (500). The work management program (420) instructs the arithmetic units (120, 220) to output first display information representing the first work time before the first work by the work device (30) begins in the target field (500). The work management program (420) instructs the arithmetic units (120, 220) to output second display information representing the second work time after the first work by the work device (30) begins in the target field (500). [Effects of the Invention]

[0011] According to the above configuration, users can check work times with greater accuracy. [Brief explanation of the drawing]

[Figure 7] This is a flowchart illustrating the processes performed by the work management system in one embodiment. [Figure 8] This is a flowchart illustrating the processes performed by the work management system in one embodiment. [Modes for carrying out the invention]

[0013] (Embodiment 1) A work management system 1000 according to this embodiment of the present invention will be described with reference to the drawings. In this embodiment, as shown in Figure 1, the work management system 1000 comprises a work management device 100 and a terminal 200. The terminal 200 is used by a user, such as a work manager, to check the working time in the field. The work management device 100 is communicated with the terminal 200 and the work device 30 via a network 20, such as the Internet.

[0014] The work device 30 performs tasks such as harvesting, transplanting, and sowing while moving around in the field. The work device 30 includes, for example, a tractor that tows a work machine, and a harvester formed integrally with the work machine.

[0015] As shown in Fig. 2, when the working device 30 is working in the target field 500, it measures the positioning position 610 representing the position of the working device 30 at each moment, and transmits the position information representing the positioning position 610 to the work management device 100. For example, the working device 30 includes a positioning device, such as a receiver of GNSS (Global Navigation Satellite System), and acquires the position information representing the positioning position 610 at each moment. Therefore, the line connecting the positioning positions 610 in the order of the times when they are measured represents the trajectory 600 along which the working device 30 has moved. For example, the line connecting the first positioning position 610-1 measured when the working device 30 starts working and the next measured second positioning position 610-2 represents a part of the trajectory 600 along which the working device 30 has moved. Therefore, the trajectory 600 along which the working device 30 has moved is represented by the line connecting from the first positioning position 610-1 to the last measured third positioning position 610-3.

[0016] Based on the position information acquired from the working device 30, the work management device 100 determines the work area 700 where the work is performed by the working device 30. For example, the work management device 100 determines the area including the trajectory 600 connecting the first positioning position 610-1 to the last measured third positioning position 610-3 with a line as the work area 700. Subsequently, the work management device 100 determines the working time required for the work in the target field 500 based on the working time when the working device 30 performs the work, the area of the determined work area 700, and the area of the target field 500.

[0017] Here, the time required for the work in the target field 500 is affected by working environments, such as weather, soil conditions, yield per unit area, etc. For example, on rainy days and sunny days, even for the same area of work, the working time is different. Also, when the yield per unit area increases, the working time required per unit area increases.

[0018] [[ID=|1]] The work management system 1000 determines the working time required for the work on the target field 500 by the work device 30 based on the position information of the work device 30 that is performing the work in the current working environment. Therefore, the determined working time can be more accurate than using past work performance. A user, for example, a work manager, can know the completion time of the work on the target field 500 by checking this determined working time.

[0019] Also, as shown in FIG. 3, before the work device 30 starts working on the target field 500, the work management system 1000 determines the working time from the start to the completion of the work of the work device 30 based on past work performance. Therefore, the user can also check the working time on the target field 500 even before starting the work by the work device 30.

[0020] The work management system 1000 may also notify the user so that the first working time determined based on past work performance and the second working time determined based on the position information of the work device 30 performing the work can be compared. Thereby, the user can check the difference between the first working time and the second working time by comparing the first working time and the second working time. The user can estimate the working time on the fields around the target field 500 based on the difference between the first working time and the second working time. For example, the user can estimate the difference between the working time determined by past work performance and the actual working time on the fields around the target field 500 based on the difference between the first working time and the second working time. Thus, the work management system 1000 supports the user in managing the working time.

[0021] (Configuration of the work management system) The configuration of the work management device 100 included in the work management system 1000 shown in Figure 1 will be described. As shown in Figure 4, the work management device 100 comprises an input / output device 110, an arithmetic unit 120, a communication device 130, and a storage device 140. The work management device 100 is, for example, a computer. The work management device 100 may also be, for example, a cloud server. Information for the arithmetic unit 120 to perform processing is input to the input / output device 110. The input / output device 110 also outputs the results of the processing performed by the arithmetic unit 120. The input / output device 110 includes various input and output devices, such as a keyboard, mouse, microphone, display, speaker, and touch panel. The input / output device 110 may be omitted.

[0022] The communication device 130 is electrically connected to the network 20 and communicates with each device via the network 20. For example, the communication device 130 transfers location information acquired from the work device 30 to the computing device 120. It also transfers signals generated by the computing 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).

[0023] The storage device 140 stores various data for determining the working time of the work performed by the work device 30, such as actual data 410, and the work management program 420. The storage device 140 is used as a non-transitory tangible storage medium for storing the work management program 420. The work management program 420 may be provided as a computer program product recorded on a computer-readable storage medium 1, or as a computer program product downloadable from a server.

[0024] The performance data 410 stores information about work previously performed by the work device 30. For example, the performance data 410 represents the work time per unit area, which is the time from the start to the completion of work in a unit area, depending on the type of work performed by the work device 30. Here, the work device 30 that performed work in the past may be the same as or different from the work device 30 that performs work in the target field 500.

[0025] The arithmetic unit 120 executes the work management program 420 and performs various data processing to determine the work time for the work performed by the work device 30. For example, the arithmetic unit 120 includes a central processing unit (CPU).

[0026] The arithmetic unit 120 reads and executes the work management program 420 to realize a first time determination unit 150, a region determination unit 160, a second time determination unit 170, and an output unit 180, as shown in Figure 5. The first time determination unit 150 determines the first work time required for the work device 30 to perform work in the target field 500 based on the actual data 410. The region determination unit 160 determines the work area where the work device 30 has performed work in the target field 500 based on the position information of the work device 30 performing work in the target field 500. The second time determination unit 170 determines the second work time required for the work device 30 to perform work in the target field 500 based on the area of ​​the work area of ​​the work device 30, the area of ​​the target field 500, and the work execution time during which the work device 30 performed work. The output unit 180 outputs display information representing at least one of the first work time and the second work time.

[0027] Next, the configuration of terminal 200 will be described. As shown in Figure 6, terminal 200 comprises an input / output device 210, an arithmetic unit 220, a communication device 230, and a storage device 240. Terminal 200 includes, for example, a computer, a tablet, a mobile phone, etc. Information for the arithmetic unit 220 to perform processing is input to the input / output device 210. The input / output device 210 also outputs the results of the processing performed by the arithmetic unit 220. The input / output device 210 includes various input and output devices, such as a keyboard, mouse, microphone, display, speaker, touch panel, etc.

[0028] The communication device 230 is electrically connected to the network 20 and communicates with each device via the network 20. For example, the communication device 230 transfers information acquired from the work management device 100 to the computing device 220. It also transfers signals generated by the computing device 220 to the work management device 100. The communication device 230 includes various interfaces such as transceivers used for wireless communication, such as wireless LAN (Local Area Network) and cellular networks, NIC (Network Interface Card), and USB (Universal Serial Bus).

[0029] The storage device 240 stores various data for displaying display information acquired from the work management device 100, such as a display program 430. The storage device 240 is used as a non-transitory tangible storage medium for storing the display program 430. The display program 430 may be provided as a computer program product recorded on a computer-readable storage medium 2, or as a computer program product downloadable from a server.

[0030] The arithmetic unit 220 executes the display program 430 and performs various data processing to display the display information acquired from the work management device 100. For example, the arithmetic unit 220 includes a central processing unit (CPU).

[0031] The arithmetic unit 220 reads and executes the display program 430, and in cooperation with the input / output device 210, realizes the display unit 250 as shown in Figure 5. The display unit 250 displays the display information acquired from the work management device 100.

[0032] (Operation of the work management system) The operation of the work management system 1000 is described below. The user inputs a display operation to the input / output device 210 of the terminal 200 to display the work time in the target field 500. When the display operation is input to the input / output device 210, the arithmetic unit 220 of the terminal 200 reads and executes the display program 430. By executing the display program 430, the arithmetic unit 220 performs the processes shown in Figures 7 and 8, which are part of the work management method.

[0033] In step S110, the display unit 250, implemented by the arithmetic unit 220, outputs a signal to the work management device 100 to request display information based on the user's display operation.

[0034] In step S120, the first time determination unit 150 of the work management device 100 determines whether work has started in the target field 500. For example, the first time determination unit 150 determines whether work has started in the target field 500 based on location information obtained from the work device 30. For example, the first time determination unit 150 determines that work has started in the target field 500 by the work device 30 when the location represented in the location information is included in the target field 500. If it is determined that work has started in the target field 500, the process proceeds to step S210 shown in Figure 8. If it is determined that work has not started in the target field 500, the first time determination unit 150 executes the process of step S130 shown in Figure 7.

[0035] In step S130, the first time determination unit 150 determines the first work time required when performing work in the target field 500, based on past performance data 410. For example, the first time determination unit 150 extracts the work time per unit area corresponding to the type of work performed in the target field 500 from the performance data 410. Based on the extracted work time per unit area and the area of ​​the target field 500, the first time determination unit 150 determines the first work time required for the work in the target field 500. For example, the first time determination unit 150 determines the first work time by adding the area of ​​the target field 500 to the work time per unit area. Here, the type of work performed in the target field 500 is entered in advance by the user into the terminal 200. Information representing the entered type of work is transmitted from the terminal 200 to the work management device 100 and stored in the storage device 140 of the work management device 100.

[0036] In step S140, the output unit 180 outputs display information representing the determined first work time to the terminal 200. For example, the display information represents the first work time in relation to the target field 500. For example, the display information may represent an image showing the area of ​​the target field 500 and a work time display area 650 that represents the first work time in relation to the area of ​​the target field 500, as shown in Figure 3.

[0037] In step S150 shown in Figure 7, the display unit 250 of the terminal 200 displays the display information acquired from the work management device 100 on the input / output device 210. Based on the display information shown on the input / output device 210, the user confirms the work time required for the work on the target field 500.

[0038] If work has started in the target field 500 in step S120, the processes from step S210 onwards shown in Figure 8 are executed. In step S210, the area determination unit 160 of the work management device 100 determines the work execution time and the work area 700 based on the position information of the work device 30.

[0039] For example, as shown in Figure 2, the area determination unit 160 determines the area surrounding the positioning position 610 of the work device 30 in the target field 500 as the work area 700. For example, the work area 700 represents the convex hull of the positioning position 610 of the work device 30. Alternatively, the work area 700 may be represented as an area where the convex hull of the positioning position 610 of the work device 30 is expanded by the working width of the work device 30. Alternatively, the work area 700 may be represented as an area where the trajectory 600 determined based on the positioning position 610 is expanded by the working width of the work device 30. Alternatively, the work area 700 may be represented by a sub-region that includes the positioning position 610 among the sub-regions obtained by dividing the target field 500.

[0040] For example, the area determination unit 160 determines the time from the first time the positioning position 610 of the work device 30 was measured to the last time it was measured in the target field 500 as the work execution time. Alternatively, the area determination unit 160 may determine the time from the time from the first time to the last time to the time when the engine of the work device 30 is stopped in the target field 500, for example, the time when the key is off, as the work execution time. Alternatively, the area determination unit 160 may determine the time from the time from the first time to the last time to the time when work is stopped, for example, the time when machine maintenance or breaks are being performed, as the work execution time. For example, the area determination unit 160 determines the time when work is stopped as the time when the work device 30 is stopped for a predetermined period of time or longer, for example, the time when the speed is less than a threshold.

[0041] In step S220 shown in Figure 8, the second time determination unit 170 determines the second working time for the work device 30 to perform work in the target field 500, based on the work execution time, the area of ​​the work area 700, and the area of ​​the target field 500. For example, the second working time represents the time required for the work device 30 to perform work in the unworked areas of the target field 500 where no work has been performed. For example, the second time determination unit 170 first determines the working time per unit area for the work performed by the work device 30 in the target field 500, based on the work execution time and the area of ​​the work area 700. For example, the second time determination unit 170 determines the working time per unit area by dividing the work execution time by the area of ​​the work area 700.

[0042] Next, the second time determination unit 170 determines the area of ​​the unworked area based on the area of ​​the target field 500 and the area of ​​the work area 700. For example, the area of ​​the unworked area is determined by subtracting the area of ​​the work area 700 from the area of ​​the target field 500.

[0043] Next, the second time determination unit 170 determines the second work time required for the work device 30 to perform work in the unworked area, based on the determined area of ​​the unworked area and the work time per unit area. For example, the second work time is determined by multiplying the work time per unit area by the area of ​​the unworked area.

[0044] In step S230, the output unit 180 outputs display information representing the determined second work time to the terminal 200. For example, the display information represents the second work time in relation to the target field 500. For example, the display information may represent an image showing the area of ​​the target field 500 and a work time display area 650 that represents the second work time in relation to the area of ​​the target field 500, as shown in Figure 2.

[0045] In step S240 shown in Figure 8, the display unit 250 of the terminal 200 displays the display information acquired from the work management device 100 on the input / output device 210. The user confirms the work time required for the work on the target field 500 based on the display information displayed on the input / output device 210. For example, the display information may include information representing the time required for the work on the entire target field 500 by the work device 30. In this case, as shown in Figure 2, the work time display area 650 may distinguish between the time required for the work on the unworked area and the time required for the work on the entire target field 500. For example, as shown in Figure 2, the time required for the work on the entire target field 500 may be represented as the total work time, and the time required for the work on the unworked area may be represented as the remaining work time.

[0046] In this way, the work management system 1000 determines and displays the work time required for the work on the target field 500 by the work device 30, based on the location information of the work device 30 currently working in the work environment. This allows the user to check the work time with greater accuracy.

[0047] Furthermore, the display unit 250 of the terminal 200 may display an image that allows the user to compare a first work time, determined based on past work performance, with a second work time, determined based on the position information of the work device 30 performing the work. In this case, in step S230 shown in Figure 8, the output unit 180 outputs display information of an image that shows the first work time and the second work time in a comparable manner. For example, the display information may represent an image that can be switched between an image representing the first work time in association with the target field 500, as shown in Figure 3, and an image representing the second work time in association with the target field 500, as shown in Figure 2. Alternatively, the display information may show an image that shows both the first work time and the second work time in association with the target field 500. For example, the display information may show an image that shows the first work time and the second work time side by side.

[0048] Thus, the work management system 1000 may display an image that allows comparison between a first work time determined based on past work performance and a second work time determined based on the location information of the work device 30 performing the work. This allows the user to estimate the work time in fields surrounding the target field 500 based on the difference between the first work time and the second work time.

[0049] (modified version) The configuration described in the embodiment is an example, and the configuration can be changed within the scope that does not impede functionality. For example, in step S130 shown in Figure 7, the first time determination unit 150 of the work management device 100 may determine the type of work to be performed by the work device 30 in any way. For example, information on the work device 30 that will perform work in the target field 500 may be entered by the user into the terminal 200. The information on the work device 30 is transmitted from the terminal 200 to the work management device 100 and stored in the storage device 140 of the work management device 100. The first time determination unit 150 determines the type of work to be performed by the work device 30 based on the information on the work device 30 stored in the storage device 140, for example, the model. In this case, the first time determination unit 150 has information registered in advance that associates the information on the work device 30, for example, the model, with the type of work performed by the work device 30. Also, the number of work types registered in the actual data 410 may be only one.

[0050] Furthermore, the performance data 410 shown in Figure 4 may represent the work time per unit area according to the type of work device 30 that performed the same work in the past, or the type of work machine towed by the work device 30. In this case, in step S130 shown in Figure 7, the first time determination unit 150 extracts the work time per unit area according to the type of work device 30 that performs work in the target field 500 from the performance data 410 and determines the first work time. Here, the first time determination unit 150 may determine the type of work device 30 by any method. For example, the type of work device 30 that performs work in the target field 500 may be entered by the user into the terminal 200.

[0051] Furthermore, the performance data 410 may represent the work time per unit area for the same work performed in the past, for each field. For example, the performance data 410 may represent the work time per unit area for the same work performed in the past in the target field 500. Alternatively, the performance data 410 may represent the work time per unit area for the same work performed in the past in a field different from the target field 500. In this case, in step S130 shown in Figure 7, the first time determination unit 150 extracts the work time per unit area for the target field 500 from the performance data 410 and determines the first work time. When the area of ​​the target field 500 does not change, the performance data 410 may represent the work time required for the entire work in the target field 500.

[0052] In step S210 shown in Figure 8, the area determination unit 160 of the work management device 100 may determine a portion of the time from the time the positioning position 610 of the work device 30 was first measured to the time it was last measured as the work execution time. For example, the area determination unit 160 may determine a portion of the time from the time the positioning position 610 was first measured to the time it was last measured as the most recent predetermined period, for example, within one day, as the work execution time. For example, the area determination unit 160 may determine the time during which work was performed on the day including the current time, for example, today, from the time from the time the positioning position 610 was first measured to the time it was last measured as the work execution time. Alternatively, the area determination unit 160 may determine the time during which work was performed on the week including the current time, for example, this week, from the time from the time the positioning position 610 was first measured to the time it was last measured as the work execution time.

[0053] In this case, the area determination unit 160 determines the partial work area where work was performed during the work execution time. For example, the partial work area represents the area surrounding the positioning position 610 measured during the work execution time. For example, the partial work area represents the convex hull for the positioning position 610 measured during the work execution time. Alternatively, the partial work area may be represented by an area where the convex hull for the positioning position 610 measured during the work execution time is expanded by the working width of the work device 30. Alternatively, the partial work area may be represented by an area where the trajectory 600 determined based on the positioning position 610 measured during the work execution time is expanded by the working width of the work device 30. Alternatively, the partial work area may be represented by a sub-region of the target field 500 that includes the positioning position 610 measured during the work execution time.

[0054] In this case, in step S220, the second time determination unit 170 determines the work time per unit time based on the area of ​​the work area 700 during the work execution time and the work execution time. Based on the determined work time per unit time and the area of ​​the unworked area, the second time determination unit 170 determines the time required for the work device 30 to perform work in the unworked area.

[0055] In step S220 shown in Figure 8, the second time determination unit 170 of the work management device 100 may determine the time required to perform work on the entire target field 500 as the second work time. In this case, in addition to the second work time, the second time determination unit 170 may also determine the time required for the work device 30 to perform work in the unworked area.

[0056] In step S230, if the work execution time is shorter than a predetermined time, for example 10 minutes, the output unit 180 of the work management device 100 may output display information showing an image indicating that the second work time for the target field 500 is being calculated.

[0057] Furthermore, the output unit 180 may output display information representing the ratio of the second work time to the first work time as display information representing the second work time. For example, the output unit 180 outputs display information showing an image representing the ratio of the second work time to the first work time in association with the area of ​​the target field 500. The image shown in the display information may represent the ratio of the second work time to the first work time together with the second work time. In this case, the display unit 250 of the terminal 200 displays the ratio of the second work time to the first work time. By checking the ratio of the second work time to the first work time, the user can estimate the actual work time in the fields surrounding the target field 500 from the first work time in each field.

[0058] Furthermore, the output unit 180 may output display information representing the time when the work in the target field 500 is completed, as display information representing the second work time.

[0059] The embodiments and modifications described above are examples, and the configurations described in each embodiment and modification may be arbitrarily changed and / or combined as long as they do not impede the function. Furthermore, some of the functions described in the embodiments and modifications may be omitted if the necessary functions can be realized. For example, some or all of the processing of the work management device 100 may be performed by the terminal 200. Alternatively, some or all of the processing of the terminal 200 may be performed by the work management device 100. The work management program 420 may also include a display program 430.

[0060] Furthermore, the work management system 1000 may not include terminal 200 and may display information on external terminals not included in the work management system 1000.

[0061] The work management system 1000 may determine the first work time and the second work time for multiple target fields 500 where work is performed by one or more work devices 30.
