MODE FOR CARRYING OUT THE INVENTION

[0012] The embodiments for implementing the work management method, work management system, and work management program according to the present disclosure will be described below with reference to the accompanying drawings.

[0013] (Embodiment) As shown in FIG. 1, a work management system 1 according to an embodiment includes a mounted terminal 20 mounted on a work device 2, worker terminals 30A and 30B respectively held by workers 3A and 3B, a work management device 5, and an administrator terminal 6 held by an administrator. Hereinafter, when workers 3A and 3B are not distinguished, they may be collectively referred to as worker 3. Also, when worker terminals 30A and 30B are not distinguished, they may be collectively referred to as worker terminal 30. The mounted terminal 20, worker terminal 30, work management device 5, and administrator terminal 6 may perform wired communication and / or wireless communication via a network 4.

[0014] The mounted terminal 20 is mounted on the working device 2. The working device 2 performs farming operations such as tilling and harvesting on the field 9 and the crops grown in the field 9 while moving on the ground. As an example, the working device 2 may be a tilling machine that performs tilling, a transplanter or rice transplanter that performs transplanting operations, a combine that performs harvesting operations, etc., or may be a tractor that pulls a working machine that performs harvesting, tilling, fertilizing, etc.

[0015] The mounted terminal 20 generates working device position information that measures the positions of a plurality of points passed through while the working device 2 is working in the field 9. The position measurement may be performed using a quantum compass that does not require an external auxiliary system such as GNSS (Global Navigation Satellite System) or artificial satellites. The point where the position of the working device 2 is measured is called a working device measurement point. The working device position information includes working device positioning time information representing the working device positioning time when the position of the working device 2 is measured at each working device measurement point. The mounted terminal 20 transmits the working device position information to the work management device 5.

[0016] The worker 3 uses the working device 2 to perform operations such as farming in the field 9. Each worker 3 holds a worker terminal 30. The worker terminal 30 may include a smartphone, a tablet terminal, a personal computer, etc. having a communication function, a display function, and an input function. The worker terminal 30 has a function of authenticating the worker 3 by authentication means such as face authentication, fingerprint authentication, voice authentication, password input, etc. Further, the worker terminal 30 generates worker position information that measures the positions of a plurality of points passed through by the authenticated worker 3 inside and outside the field 9 during or before and after the work. The position measurement may be performed using a quantum compass that does not require an external auxiliary system such as GNSS or artificial satellites. The point where the position of the worker 3 is measured is called a worker measurement point. The worker position information includes worker positioning time information representing the worker positioning time when the position is measured at each worker measurement point. The mounted terminal 20 transmits the worker position information to the work management device 5.

[0017] The work management device 5 estimates the relationship between work device 2 and worker 3 based on the work device location information received from the onboard terminal 20 and the worker location information received from the worker terminal 30. The relationship between work device 2 and worker 3 represents, for example, whether or not work device 2 is being used by any of the workers 3. The work management device 5 generates an icon representing the estimation result and displays the icon on the map at the location corresponding to the positions of work device 2 and worker 3. The work management device 5 may also record the estimation result and evaluate the work efficiency of the work performed by each worker 3 using work device 2 based on past records. The work management device 5 may transmit map information including the icon, evaluation information representing the results of the work efficiency evaluation, etc., to the administrator terminal 6.

[0018] The administrator terminal 6 may include a smartphone, tablet, or personal computer having communication, display, and input functions. The administrator terminal 6 receives map information from the work management device 5 and displays a map of the area including the field 9, and icons representing the work device 2 and worker 3, respectively, at positions on the map corresponding to the locations of the work device 2 and worker 3, in a manner visible to the administrator using the administrator terminal 6. The administrator terminal 6 may further receive evaluation information from the work management device 5 and display the evaluation for each worker 3 represented by the evaluation information in a manner visible to the administrator.

The positioning unit 221 measures the position of the work device 2 at each of a plurality of time points. For example, the positioning unit 221 measures the position of the work device 2 at predetermined intervals such as one second or one minute. The time at which the positioning unit 221 measures the position is called the positioning time. The positioning unit 221 generates work device position information by associating work device positioning information, which represents the measured position of the work device 2, with work device positioning time information, which represents the positioning time at which each position was measured. The positioning unit 221 may store the work device position information in the data storage unit 232 of the storage device 23. The transmission unit 222 transmits the work device position information to the work management device 5.

[0026] The arithmetic unit 32 implements the processing of the authentication unit 321, the positioning unit 322, and the transmission unit 323 by executing at least a part of the work management program according to one embodiment. The authentication unit 321, the positioning unit 322, and the transmission unit 323 are each virtual functional blocks that execute processing realized by the cooperation of the arithmetic unit 32 and the storage device 33. The authentication unit 321 authenticates the worker 3 who possesses the worker terminal 30. The positioning unit 322 measures the position of the worker 3 at each of several time points. For example, the positioning unit 322 measures the position of the worker 3 at predetermined intervals such as one second or one minute. The time at which the positioning unit 322 measures the position is called the positioning time. The positioning unit 322 generates worker position information by associating worker positioning information, which represents the measured position of the worker 3, with worker positioning time information, which represents the positioning time at which each position was measured. The positioning unit 322 may store the worker location information in the data storage unit 332 of the storage device 33. The transmission unit 323 transmits the worker location information to the work management device 5. The transmission unit 323 may also transmit worker authentication information, which represents the result of authenticating the worker 3 possessing the worker terminal 30, to the work management device 5 together with the worker location information.

[0027] The storage device 33 comprises a program storage unit 331 and a data storage unit 332. At least a portion of the work management program may be read from an external recording medium 330 and stored in the program storage unit 331. The recording medium 330 may be a non-temporary, tangible medium. The data storage unit 332 may store worker location information generated by the positioning unit 322.

[0030] The authentication device 36, under the control of the authentication unit 321, authenticates the worker 3 using authentication methods such as facial recognition, fingerprint recognition, voice recognition, and password input.

[0031] The positioning device 37 measures the position of worker 3 under the control of the positioning unit 322. The positioning device 37 may also measure the position of worker 3 using GNSS or the like.

[0032] As shown in Figure 4, the work management device 5 according to one embodiment may be configured as a so-called computer. In the example in Figure 4, the work management device 5 includes a bus 51, an arithmetic unit 52, a storage device 53, a communication device 54, and an input / output device 55. The bus 51 may be configured to enable communication between the arithmetic unit 52, the storage device 53, the communication device 54, and the input / output device 55.

[0033] The arithmetic unit 52 implements the processing of the information acquisition unit 521, the relationship estimation unit 522, the icon generation unit 523, and the output unit 524 by executing at least a part of the work management program according to one embodiment. Each of the information acquisition unit 521, the relationship estimation unit 522, the icon generation unit 523, and the output unit 524 is a virtual functional block that executes processing realized by the cooperation of the arithmetic unit 52 and the storage device 53. The information acquisition unit 521 receives and acquires work device location information from the mounted terminal 20 in Figure 2 and worker location information from the worker terminal 30 in Figure 3. The information acquisition unit 521 may store the acquired work device location information and worker location information in the data storage unit 532 of the storage device 53. The relationship estimation unit 522 estimates the relationship between the work device 2 and worker 3 based on the work device location information and worker location information. As an example, the relationship estimation unit 522 estimates whether or not the work device 2 is being used by worker 3. The relationship estimation unit 522 may store the estimation result in the data storage unit 532 of the storage device 53. The icon generation unit 523 generates icons for the work device 2 and the worker 3 based on the estimation result. If the icon generation unit 523 estimates that the work device 2 is being used by the worker 3, it generates an integrated icon of the work device 2 and the worker 3 representing the estimation result. The output unit 524 outputs information for displaying the generated icons at the locations of the work device 2 and / or the worker 3 on a map representing the field 9, based on the work device location information and the worker location information. The output unit 524 may transmit this information to the administrator terminal 6.

[0034] The storage device 53 comprises a program storage unit 531 and a data storage unit 532. At least a portion of the work management program may be read from an external recording medium 530 and stored in the program storage unit 531.

The data storage unit 532 may also store a work device database, which associates work device identification information that identifies each of the work devices 2 managed by the work management device 5 with work device characteristic information that represents the characteristics of each work device 2, even before the work management device 5 starts operation.

[0035] The communication device 54 communicates with external devices, including the onboard terminal 20, the worker terminal 30, and the administrator terminal 6, via wireless communication over the network 4. At least a portion of the work management program may be received from an external source by the communication device 54 and stored in the program storage unit 531.

[0036] The input / output device 55 outputs information to the user and accepts user input. For example, the input / output device 55 includes a display device that outputs images, a keyboard and / or mouse that accept input.

[0037] As shown in Figure 5, the administrator terminal 6 in one embodiment may be configured as a so-called computer. In the example in Figure 5, the administrator terminal 6 includes a bus 61, an arithmetic unit 62, a storage device 63, a communication device 64, and an input / output device 65.

[0038] The arithmetic unit 62 implements the processing of the receiving unit 621 and the display unit 622 by executing at least a part of the work management program according to one embodiment. The receiving unit 621 and the display unit 622 are virtual functional blocks that execute processing realized by the cooperation of the arithmetic unit 62 and the storage device 63. The receiving unit 621 receives information transmitted by the work management device 5 in Figure 4. The receiving unit 621 may store the received information in the data storage unit 632 of the storage device 63 in Figure 5. Based on the information received from the work management device 5, the display unit 622 displays an icon representing the location of the work device 2 and / or worker 3 on the map representing the field 9 at the location of the work device 2 and / or worker 3, so that it can be seen by the manager. The icon may be an integrated icon representing the relationship between the work device 2 and worker 3 when the work device 2 is being used by worker 3.

[0039] The storage device 63 comprises a program storage unit 631 and a data storage unit 632. At least a portion of the work management program may be read from an external recording medium 630 and stored in the program storage unit 631.

[0040] The communication device 64 communicates with external devices, including the work management device 5, via wireless communication over the network 4. At least a portion of the work management program may be received from an external source by the communication device 64 and stored in the program storage unit 631.

[0041] The input / output device 65 outputs information to the administrator and accepts input operations from the administrator. As an example, the input / output device 65 includes a touch panel that integrates a display device that outputs images and a touch pad that accepts input via touch operation.

[0042] An example of the processing of the work management method according to one embodiment will be described with reference to the flowcharts in Figures 6, 7A, and 7B. The work management method may be started when the mounted terminal 20, the worker terminal 30, the work management device 5, and the administrator terminal 6 are started up. At this time, the processing of the work management method shown in the flowcharts in Figures 6, 7A, and 7B is realized when each of the mounted terminal 20 in Figure 2, the worker terminal 30 in Figure 3, the work management device 5 in Figure 4, and the administrator terminal 6 in Figure 5 executes at least a part of the work management program.

[0043] When the work management method processing is initiated, step S1 in Figure 6 is executed. In step S1, the information acquisition unit 521 of the work management device 5 in Figure 4 acquires information. This information includes work device location information and work device identification information transmitted by the transmission unit 222 of the mounted terminal 20 in Figure 2, and worker location information and worker authentication information transmitted by the transmission unit 323 of the worker terminal 30 in Figure 3.

[0044] After step S1 in Figure 6, step S2 is executed. In step S2, the relationship estimation unit 522 of the work management device 5 in Figure 4 calculates the distance between the work device 2 and the worker 3. More specifically, the relationship estimation unit 522 calculates the distance between the work device 2 and the worker 3 when the positioning time for measuring the position of the work device 2 and the positioning time for measuring the position of the worker 3 are sufficiently close. For example, the relationship estimation unit 522 calculates the distance between the work device 2 and the worker 3 when the time between the positioning time of the work device 2 and the positioning time of the worker 3 is shorter than a predetermined first threshold time. For example, the first threshold time may be determined based on at least one of the period for measuring the position of the work device 2, the period for measuring the position of the worker 3, the movement speed of the work device 2, and the movement speed of the worker 3. If there are multiple workers 3, the relationship estimation unit 522 calculates the distance from the work device 2 to each worker 3. Furthermore, if there are multiple work devices 2, the relationship estimation unit 522 calculates the distance from each work device 2 to each worker 3. The relationship estimation unit 522 may store the information representing the calculated distance in the data storage unit 532.

[0045] After step S2 in Figure 6, step S3 is executed. In step S3, the relationship estimation unit 522 of the work management device 5 in Figure 4 estimates the relationship between the work device 2 and the worker 3. More specifically, the relationship estimation unit 522 estimates whether the work device 2 of interest is currently being used by any of the workers 3, based on the work device location information, work device identification information, worker location information, and worker authentication information acquired in step S1 in Figure 6, and the distance calculated in step S2. Details of step S3 in Figure 6 will be described later.

[0046] After step S3 in Figure 6, step S4 is executed. In step S4, the relationship estimation unit 522 of the work management device 5 in Figure 4 records the relationship between the work device 2 and the worker 3. More specifically, the relationship estimation unit 522 stores the relationship between the work device 2 and the worker 3 estimated in step S3 in Figure 6 in the data storage unit 532 in Figure 4, associating it with the positioning time of the work device 2 used to estimate the relationship and the positioning time of the worker 3 used to estimate the relationship.

[0047] After step S4 in Figure 6, step S5 is executed. In step S5, the icon generation unit 523 of the work management device 5 in Figure 4 generates icons for the work device 2 and the worker 3. More specifically, the icon generation unit 523 generates icons for the work device 2 and the worker 3 based on the relationship inferred in step S3 in Figure 6. If the work device 2 is being used by the worker 3, the icon generation unit 523 may generate an integrated icon representing the relationship between the work device 2 and the worker 3. Specific examples of these icons will be described later.

[0048] After step S5 in Figure 6, step S6 is executed. In step S6, the display unit 622 of the administrator terminal 6 in Figure 5 displays icons for the work device 2 and the worker 3. More specifically, based on the information transmitted by the output unit 524 of the work management device 5 in Figure 4 and received by the receiver unit 621 of the administrator terminal 6 in Figure 5, the display unit 622 displays icons representing the location and relationship of the work device 2 and the worker 3 on a map of the area including the field 9, at positions corresponding to the locations of the work device 2 and the worker 3, so that the administrator can see them.

[0049] After step S6 in Figure 6, the processes of the mounted terminal 20 in Figure 2, the worker terminal 30 in Figure 3, the work management device 5 in Figure 4, and the administrator terminal 6 in Figure 5 return to step S1, and the processes from step S1 to step S6 are repeated.

[0050] Referring to the flowcharts in Figures 7A and 7B, the process of step S3 in Figure 6 will be explained. When step S3 starts, step S301 in Figure 7A is executed.

[0051] In step S301 of Figure 7A, the relationship estimation unit 522 of the work management device 5 in Figure 4 extracts nearby workers from among the workers 3 who are close to the work device 2. As an example, based on the work device location information and worker location information, the relationship estimation unit 522 extracts workers 3 who are located at a distance shorter than a predetermined first threshold distance from the work device 2 of interest as nearby workers. The relationship estimation unit 522 may store the worker authentication information of the extracted nearby workers in the data storage unit 532 of Figure 4. Note that there may be cases where there are no workers 3 near the work device 2, i.e., no nearby workers.

[0052] After step S301 in Figure 7A, step S302 is executed. In step S302, the relationship estimation unit 522 of the work management device 5 in Figure 4 determines whether or not a nearby worker exists. If no nearby worker exists (step S302 in Figure 7A: No), the process proceeds to step S303. If a nearby worker exists (step S302: Yes), the process proceeds to step S309.

[0053] In step S303 of Figure 7A, the relationship estimation unit 522 of the work management device 5 in Figure 4 determines whether or not the work device 2 is moving. More specifically, the relationship estimation unit 522 calculates the vehicle speed of the work device 2 based on the work device position information of the work device 2 under consideration, and determines that the work device 2 is moving if the vehicle speed is greater than a predetermined first threshold speed. For example, the first threshold speed may be determined based on the error in measuring the position of the work device 2. If the work device 2 is moving (step S303 in Figure 7A: Yes), the process proceeds to step S304. If the work device 2 is not moving (step S303: No), the process proceeds to step S308.

[0054] In step S304 of Figure 7A, the relationship estimation unit 522 of the work management device 5 in Figure 4 determines whether or not the work device 2 is capable of automatic operation. More specifically, the relationship estimation unit 522 extracts work device characteristic information representing the characteristics of the work device 2 from the work device database stored in the data storage unit 532, based on the work device identification information received from the work device 2 of interest. From the work device characteristic information, the relationship estimation unit 522 reads information indicating whether or not the work device 2 of interest is capable of automatic operation. If it is determined that the work device 2 is capable of automatic operation (step S304 in Figure 7A: Yes), the process proceeds to step S305. If it is determined that the work device 2 is not capable of automatic operation (step S304: No), the process proceeds to step S306.

[0055] In step S305 of Figure 7A, the relationship estimation unit 522 of the work management device 5 in Figure 4 determines whether or not the work device 2 is in automatic operation mode. More specifically, based on the work device identification information received from the work device 2 of interest, the relationship estimation unit 522 reads information of the remote control device associated with the work device 2 from the work device database stored in the data storage unit 532. Based on the information of the remote control device, the relationship estimation unit 522 communicates with the remote control device and requests an automatic operation mode signal indicating whether or not the remote control device is causing the work device 2 to perform automatic operation. When the relationship estimation unit 522 receives the automatic operation mode signal from the remote control device, it determines that the work device 2 is in automatic operation mode. If it is determined that the work device 2 is in automatic operation mode (step S305 in Figure 7A: Yes), the process proceeds to step S307 in Figure 7B. If the relationship estimation unit 522 does not receive the automatic operation mode signal within a predetermined time, it determines that the work device 2 is not in automatic operation mode. If it is determined that the work device 2 is not in automatic operation mode (step S305: No in Figure 7A), the process proceeds to step S306.

[0056] In step S306 of Figure 7A, the relationship estimation unit 522 of the work management device 5 in Figure 4 estimates that the work device 2 is being used by a worker who does not have a worker terminal. At this time, considering the possibility that the work device 2 has been moved for reasons other than use by a worker, such as the work device 2 being stolen, the relationship estimation unit 522 may control the communication device 54 to send a warning signal to the administrator terminal 6 in Figure 5. When the receiving unit 621 of the administrator terminal 6 receives the warning signal, the display unit 622 may control the input / output device 65 to display information representing the content of the warning. The administrator operating the administrator terminal 6 can check the status of the work device 2 without delay in response to the warning. The relationship estimation unit 522 may store the result of the estimation in the data storage unit 532. After step S306, the processing of the flowcharts in Figures 7A and 7B is completed, and the process proceeds to step S4 in Figure 6.

[0057] In step S307 of Figure 7B, the relationship estimation unit 522 of the work management device 5 in Figure 4 estimates that the work device 2 is in automatic operation mode. When the work device 2 is in automatic operation mode, it is not being used by any worker 3. The relationship estimation unit 522 may store the result of the estimation in the data storage unit 532. After step S307, the processing of the flowcharts in Figures 7A and 7B is completed, and the process proceeds to step S4 of Figure 6.

[0058] In step S308 of Figure 7A, the relationship estimation unit 522 of the work management device 5 in Figure 4 estimates that work device 2 is not in use. When work device 2 is not in use, it is stopped and not being used by any worker 3. The relationship estimation unit 522 may store the result of the estimation in the data storage unit 532. After step S308, the processing of the flowcharts in Figures 7A and 7B is completed, and the process proceeds to step S4 of Figure 6.

[0059] In step S309 of Figure 7A, the relationship estimation unit 522 of the work management device 5 in Figure 4 identifies the nearest worker from among the nearby workers who is closest to the work device 2. More specifically, the relationship estimation unit 522 identifies the nearest worker from among the nearby workers extracted in step S301 of Figure 7A who is closest to the work device 2 of interest. The identified nearest worker will henceforth be referred to as the nearest worker to the work device 2 of interest. The relationship estimation unit 522 may store information representing the result of identifying the nearest worker in the data storage unit 532.

[0060] After step S309 in Figure 7A, step S310 in Figure 7B is executed. In step S310, the relationship estimation unit 522 of the work management device 5 in Figure 4 determines whether or not the work device 2 is moving. More specifically, similar to step S303 in Figure 7A, the relationship estimation unit 522 calculates the vehicle speed of the work device 2 based on the work device position information of the work device 2 under consideration, and determines that the work device 2 is moving if the vehicle speed is greater than a predetermined first threshold speed. If the work device 2 is moving (step S310 in Figure 7B: Yes), the process proceeds to step S311. If the work device 2 is not moving (step S310: No), the process proceeds to step S312.

[0061] In step S311 of Figure 7B, the relationship estimation unit 522 of the work management device 5 in Figure 4 estimates that work device 2 is being used by the nearest worker. More specifically, the relationship estimation unit 522 estimates that the work device 2 of interest is being used by the nearest worker among the workers 3, who was identified in step S309 of Figure 7A. The relationship estimation unit 522 may store the result of the estimation in the data storage unit 532. After step S311, the processing of the flowcharts in Figures 7A and 7B is completed, and the process proceeds to step S4 of Figure 6.

[0062] In step S312 of Figure 7B, the relationship estimation unit 522 of the work management device 5 in Figure 4 determines whether the nearest worker is the last worker to use the work device 2. More specifically, the relationship estimation unit 522 determines whether the nearest worker identified in step S309 of Figure 7A is the last worker among the workers 3. Here, the last worker is the worker 3 who last used the work device 2 of interest or the worker 3 who is currently using the work device 2. The relationship estimation unit 522 may identify the last worker based on the relationship between the work device 2 and worker 3 estimated in step S3 of Figure 6 and recorded in step S4, which was executed in the past. In this case, the relationship estimation unit 522 may refer to the information stored in the data storage unit 532. If the nearest worker is not the last worker (step S312: No in Figure 7B), the process proceeds to step S313. If the nearest worker is the last worker (step S312: Yes), the process proceeds to step S314.

[0063] In step S313 of Figure 7B, the relationship estimation unit 522 of the work management device 5 in Figure 4 determines whether the last worker is close to the work device 2. For example, based on the work device position information and the worker position information, the relationship estimation unit 522 determines that the last worker is close to the work device 2 if the distance from the work device 2 of interest to the last worker is shorter than a predetermined first threshold distance. If the last worker is close to the work device 2 (step S313 in Figure 7B: Yes), the process proceeds to step S314. If the last worker is not close to the work device 2 (step S313 in Figure 7B: No), the process proceeds to step S315.

[0064] In step S314 of Figure 7B, the relationship estimation unit 522 of the work management device 5 in Figure 4 estimates that the last worker is on break. For example, when work device 2 is being used by the last worker, but the last worker is on break, a situation occurs where work device 2 is stopped and the last worker is near work device 2. After step S314, the processing of the flowcharts in Figures 7A and 7B is completed, and the process proceeds to step S4 of Figure 6.

[0065] In step S315 of Figure 7B, the relationship estimation unit 522 of the work management device 5 in Figure 4 estimates that the nearest worker is on break. For example, a situation occurs where the last worker who was using work device 2 is replaced by the nearest worker, the last worker moves away from work device 2, and the work device 2 under consideration is stopped, and the nearest worker is near work device 2, until the nearest worker starts using work device 2. After step S315, the processing of the flowcharts in Figures 7A and 7B is completed, and the process proceeds to step S4 of Figure 6.

[0066] Referring to Figures 8, 9, 10, 11, 12, and 13, examples of icons representing the work apparatus 2 and / or worker 3 will be described.

[0067] Figure 8 shows an example of the display of the touch panel 651 as an input / output device 65 of the administrator terminal 6 shown in Figure 5, in step S6 of Figure 6. In the example in Figure 8, the touch panel 651 displays a map 91 of the area including the field 9, and a table 92 of the work equipment 2 and workers 3 located within the area of ​​the map 91. As shown in Figure 8, the touch panel 651 may display a work equipment icon 72 representing the work equipment 2, superimposed on the map 91 at a position on the map 91 corresponding to the location of the work equipment 2. The touch panel 651 may also display a worker icon 73 representing the worker 3, superimposed on the map 91 at a position on the map 91 corresponding to the location of the worker 3. Here, the distance between the work equipment 2 represented by the work equipment icon 72 and the worker 3 represented by the worker icon 73 is greater than or equal to a first threshold distance, and the work equipment icon 72 and the worker icon 73 are displayed separately.

[0068] Furthermore, the touch panel 651 may display an integrated icon 74 representing the work device 2 currently in use by the worker 3 and the worker 3, superimposed on the map 91 at a position corresponding to the location of the work device 2. Here, the distance between the work device 2 and the worker 3 represented by the integrated icon 74 is shorter than the first threshold distance.

[0069] As shown in the example in Figure 8, the touch panel 651 may simultaneously display multiple work device icons 72 representing multiple work devices 2. The touch panel 651 may also simultaneously display multiple worker icons 73 representing multiple workers. Similarly, the touch panel 651 may simultaneously display multiple integration icons 74. Furthermore, the touch panel 651 may display in a table 92 the correspondence between the work devices 2 represented by the work device icons 72 and / or integration icons 74, the workers 3 represented by the worker icons 73 and / or integration icons 74, and the field 9 where the work devices 2 and / or workers 3 are located.

[0070] As shown in Figure 9, the work device icon 72 includes a position display image 721, a type display image 722, and a status display image 723. The work device icon 72 may further include a detail display image 724. The positional relationship between the position display image 721, the type display image 722, and the status display image 723 may be fixed. Also, if the detail display image 724 is displayed, the positional relationship between the detail display image 724 and the position display image 721, the type display image 722, and the status display image 723 may be fixed.

[0071] The location display image 721 shows the location on the map 91 of the work device 2 represented by the work device icon 72, as indicated by the latest work device location information. In the example in Figure 9, the shape of the location display image 721 includes a downward-pointing triangle, and the downward-pointing vertex of the triangle indicates the location of the work device 2 on the map 91.

[0072] The type display image 722 represents the type of work device 2 represented by the work device icon 72. In the example in Figure 9, the type display image 722 indicates that work device 2 is a tractor.

[0073] The status display image 723 represents the status of the work device 2, as indicated by the work device icon 72. For example, the status display image 723 may display the first state, in which the work device 2 is stopped, and the second state, in which the work device 2 is moving, using differences in color, pattern, shape, etc., so that the administrator can easily distinguish between them.

[0074] The detailed display image 724 shows the details of the work device 2 represented by the work device icon 72. For example, the detailed display image 724 includes the name of the work device 2 and the latest positioning time included in the latest work device location information received from the terminal 20 on which the work device 2 is mounted. The detailed display image 724 may be displayed temporarily when desired by the administrator. For example, the administrator may toggle the display and hiding of the detailed display images 724 of all work device icons 72 displayed on the touch panel 651 of Figure 8 at once by operating the touch panel 651 of Figure 8. As another example, the administrator may toggle the display and hiding of the detailed display image 724 of each work device icon 72 individually by operating the work device icon 72 displayed on the touch panel 651 of Figure 8.

[0075] The work device icon 72 in Figure 9 indicates that work device 2 is not being used by any worker 3 and is therefore stopped. For example, in step S308 of Figure 7A, if it is inferred that work device 2 is not being used, work device 2 in Figure 9 may be displayed.

[0076] As shown in Figure 10, the worker icon 73 includes a location display image 731, a worker display image 732, and a status display image 733. The worker icon 73 may further include a detail display image 734. The positional relationship between the location display image 731, the worker display image 732, and the status display image 733 may be fixed. Also, if the detail display image 734 is displayed, the positional relationship between the detail display image 734 and the location display image 731, the worker display image 732, and the status display image 733 may be fixed.

[0077] The location display image 731 shows the location on the map 91 of worker 3, represented by the worker icon 73, as indicated by the latest worker location information. In the example in Figure 10, the shape of the location display image 731 includes a downward-pointing triangle, and the downward-pointing vertex of the triangle indicates the location of worker 3 on the map 91.

[0078] The worker identification image 732 includes an image that identifies worker 3, represented by the worker icon 73. For example, the worker identification image 732 may be a photograph of worker 3's face.

[0079] The status display image 733 represents the status of worker 3, as indicated by the worker icon 73. For example, the status display image 733 may display the first state, where worker 3 is stopped, and the second state, where worker 3 is moving, using differences in color, pattern, shape, etc., so that the administrator can easily distinguish between them.

[0080] The detailed display image 734 shows the details of worker 3 represented by the worker icon 73. For example, the detailed display image 734 may include the name of worker 3 and the latest positioning time included in the latest worker location information received from worker terminal 30 of worker 3. The detailed display image 734 may be displayed temporarily when desired by the administrator. For example, the administrator may toggle the display and hiding of the detailed display images 734 for all worker icons 73 displayed on the touch panel 651 of Figure 8 at once by operating the touch panel 651 of Figure 8. As another example, the administrator may toggle the display and hiding of the detailed display image 734 for each worker icon 73 displayed on the touch panel 651 of Figure 8 individually by operating the worker icon 73.

[0081] As shown in Figure 11, the integrated icon 74 includes a location display image 721, a type display image 722, a status display image 723, and a worker display image 732. The integrated icon 74 may further include a detail display image 744. The positional relationships of the location display image 721, type display image 722, status display image 723, and worker display image 732 may be fixed. Also, if the detail display image 744 is displayed, the positional relationship of the detail display image 744 with respect to the location display image 721, type display image 722, status display image 723, and worker display image 732 may be fixed.

[0082] The position display image 721 of the integrated icon 74 may be the same as the position display image 721 included in the work device icon 72 shown in Figure 9. The type display image 722 of the integrated icon 74 may be the same as the type display image 722 included in the work device icon 72 shown in Figure 9. The status display image 723 of the integrated icon 74 may be the same as the status display image 723 included in the work device icon 72 shown in Figure 9.

[0083] The worker display image 732 included in the integrated icon 74 may be the same as the worker display image 732 included in the worker icon 73 in Figure 10. However, the placement of the worker display image 732 in the integrated icon 74 may be moved to a different location so as not to overlap with the type display image 722 in the integrated icon 74. In the example in Figure 11, the worker display image 732 included in the integrated icon 74 is placed to the upper right of the status display image 723 included in the integrated icon 74.

[0084] The detailed display image 724 included in the integrated icon 74 represents the details of the work device 2 and worker 3 represented by the integrated icon 74. For example, the detailed display image 724 includes the name of the work device 2, the name of worker 3, and the latest positioning time included in the latest work device location information received from the terminal 20 mounted on the work device 2. The detailed display image 744 may be displayed temporarily when desired by the administrator. For example, the administrator may switch the display and hiding of the detailed display images 744 of all integrated icons 74 displayed on the touch panel 651 of Figure 8 at once by operating the touch panel 651 of Figure 8. As another example, the administrator may switch the display and hiding of the detailed display images 744 of each integrated icon 74 individually by operating the integrated icon 74 displayed on the touch panel 651 of Figure 8.

[0085] The integrated icon 74 shown in the example in Figure 11 indicates that the work device 2 is in use by worker 3 and is in transit. In this case, the administrator can infer that worker 3 is using the work device 2 to perform a task. For example, in step S311 of Figure 7B, if it is inferred that the work device 2 is in use by the nearest worker, the integrated icon 74 of Figure 11 may be displayed. Also, in step S306 of Figure 7A, if it is inferred that the work device 2 is in use by a worker who does not have a worker terminal, and therefore it is unknown who the worker using the work device 2 is, an icon may be displayed that omits the worker display image 732 from the integrated icon 74 of Figure 11.

[0086] As shown in Figure 12, the integrated icon 74 can indicate that the work device 2 being used by worker 3 is stopped by switching the status display image 723. When the work device 2 being used by worker 3 is stopped, the manager can infer that worker 3 is resting, either while on the work device 2 or near the work device 2. For example, in step S315 of Figure 7B, the integrated icon 74 in Figure 12 may be displayed when it is inferred that the nearest worker is resting. Alternatively, in another example, the integrated icon 74 in Figure 12 may also be displayed in step S314 of Figure 7B when it is inferred that the last worker is resting.

[0087] As shown in Figure 13, the integrated icon 74 can indicate that the work device 2 is in automatic operation (auto mode) by replacing the worker display image 732 with the automatic operation display image 742. Even if the work device 2 is moving but not being used by any worker 3, the administrator can infer that the work device is in automatic operation. For example, in step S307 of Figure 7B, when it is inferred that the work device 2 is in automatic operation, the integrated icon 74 of Figure 13 may be displayed.

[0088] (Variations in how icons are displayed) In the above embodiment, as shown in Figure 11, a configuration was described in which, in the integrated icon 74, a type display image 722 is placed in the center, a status display image 723 is placed around the type display image 722, a position display image 721 is placed below the status display image 723, and a worker display image 732 is placed to the upper right of the status display image 723. As a variation of this configuration, instead of displaying the integrated icon 74 shown in Figure 11, the work device icon 72 shown in Figure 9 and the worker icon 73 shown in Figure 10 may be displayed, switching between them according to the user's operation. For example, first, in step S5 of Figure 6, the work device icon 72 and the worker icon 73 are generated, and in step S6, only the work device icon 72 is displayed. Then, in step S6 of Figure 6, when the user operates on the work device icon 72 and the input / output device 65 of Figure 5 receives the operation, the display unit 622 switches the display from the work device icon 72 to the display of the worker icon 73. Furthermore, when the user performs an operation on the worker icon 73 and the input / output device 65 receives the operation, the display unit 622 switches the display of the worker icon 73 to the display of the work device icon 72. Thereafter, each time the user performs an operation on the work device icon 72 or the worker icon 73, the display of the work device icon 72 and the display of the worker icon 73 may be switched alternately.

[0089] (A variation of the work device icon) In the above embodiment, as shown in Figure 9, a configuration was described in which the work device icon 72 includes a position display image 721, a type display image 722, and a status display image 723. As a variation of this configuration, the work device icon 72 may be an integrated unit of the position display image 721 and either the type display image 722 or the status display image 723. For example, the work device icon 72 may be an integrated unit of the position display image 721 and the type display image 722, or an integrated unit of the position display image 721 and the status display image 723. In other words, one of the type display image 722 and the status display image 723 may be omitted from the work device icon 72 shown in Figure 9. Similarly, one of the type display image 722 and the status display image 723 may be omitted from the integrated icon 74 shown in Figure 11.

[0090] (Examples of work device icons and integration icons) The work device icon 72 shown in Figure 9 and the integrated icon 74 shown in Figure 11 may display some or all of the location display image 721, type display image 722, status display image 723, worker display image 732, and detail display image 724 included in each image individually in any color. By displaying various information such as the location of the work device 2, the type of work device 2, the status of the work device 2, the worker 3, and details in different colors, users can more intuitively identify each icon and each image.
