Detailed Implementation

[0030] The following description, with reference to the accompanying drawings, illustrates the methods, management systems, and procedures for implementing the work management involved in this disclosure.

[0031] (Implementation Method)

[0032] like Figure 1As shown, one embodiment of the job management system 1 includes: a terminal 20 mounted on a job device 2; worker terminals 30A and 30B held by workers 3A and 3B respectively; a job management device 5; and a manager terminal 6 held by a manager. Hereinafter, when not distinguishing between workers 3A and 3B, they are sometimes collectively referred to as worker 3. Similarly, when not distinguishing between worker terminals 30A and 30B, they are sometimes collectively referred to as worker terminal 30. The terminal 20, worker terminals 30, job management device 5, and manager terminal 6 can communicate via wired and / or wireless communication through a network 4.

[0033] Terminal 20 is mounted on working device 2. Working device 2 moves on the ground while performing agricultural operations such as tilling and harvesting on the field 9 and the crops cultivated in the field 9. As an example, working device 2 can be a tiller for tilling, a transplanter or rice transplanter for transplanting, a combine harvester for harvesting, or a tractor for towing working machines for harvesting, tilling, fertilizing, etc.

[0034] The terminal 20 generates location information for the work device 2 as it operates within the field 9, indicating the positions of various locations it passes through. Position determination can be performed using a quantum compass or similar device that does not require external auxiliary systems such as GNSS (Global Navigation Satellite System) or artificial satellites. The locations where the work device 2's position is determined are called work device positioning points. The work device location information includes work device positioning time information, indicating the time at which the work device 2's position was determined at each work device positioning point. The terminal 20 then transmits the work device location information to the work management device 5.

[0035] Worker 3 uses work equipment 2 to perform agricultural operations or other tasks in field 9. Worker 3 carries a worker terminal 30. Worker terminal 30 may include smartphones, tablets, personal computers, etc., with communication, display, and input functions. Worker terminal 30 has the function of authenticating worker 3 through authentication methods such as facial recognition, fingerprint authentication, voice authentication, and password input. In addition, worker terminal 30 generates worker location information, determining the location of each of the authenticated worker 3 at multiple locations within or outside the field 9 during or before / after work. Location determination can be performed using a quantum compass or similar device that does not require external auxiliary systems such as GNSS or artificial satellites. The location where worker 3's position is determined is called a worker positioning point. Worker location information includes worker positioning time information indicating the time at which the position was determined at each worker positioning point. Terminal 20 transmits the worker location information to work management device 5.

[0036] The job management device 5 estimates the relationship between the job device 2 and the operator 3 based on the job device location information received from the onboard terminal 20 and the operator location information received from the operator terminal 30. For example, the relationship between the job device 2 and the operator 3 indicates whether the job device 2 is being used by either operator 3. The job management device 5 generates an icon representing the estimation result and displays the icon on a map at a location corresponding to the positions of the job device 2 and the operator 3. Furthermore, the job management device 5 can record the estimation results and evaluate the work efficiency of each operator 3 using the job device 2 based on past records. The job management device 5 can send map information including the icon and evaluation information representing the evaluation results of work efficiency to the manager terminal 6.

[0037] The manager terminal 6 may include a smartphone, tablet, personal computer, or similar device with communication, display, and input functions. The manager terminal 6 receives map information from the work management device 5 and displays a map of the area including the field 9, along with icons representing the work device 2 and the worker 3 at locations on the map corresponding to their respective positions, in a manner that allows the manager using the terminal 6 to visually confirm the map. The manager terminal 6 may further receive evaluation information from the work management device 5 and display the evaluation information for each worker 3 in a manner that allows the manager to visually confirm the evaluation.

The positioning unit 221 and the sending unit 222 are virtual functional modules that perform the processing implemented by the computing unit 22 and the storage unit 23 in cooperation. The positioning unit 221 measures the position of the work device 2 at multiple times. As an example, the positioning unit 221 measures the position of the work device 2 at predetermined intervals such as 1 second or 1 minute. The time when the positioning unit 221 measures the position is called the positioning time. The positioning unit 221 generates work device positioning information that establishes a correlation between work device positioning information indicating the measured position of the work device 2 and work device positioning time information indicating the positioning time of each position measurement. The positioning unit 221 can store the work device position information in the data storage unit 232 of the storage unit 23.

The authentication unit 321 authenticates the operator 3 holding the operator terminal 30. The positioning unit 322 measures the position of the operator 3 at multiple times. For example, the positioning unit 322 measures the position of the operator 3 at predetermined intervals such as 1 second or 1 minute. The time when the positioning unit 322 measures the position is called the positioning time. The positioning unit 322 generates operator position information that establishes a correlation between operator position information representing the measured position of the operator 3 and operator position time information representing the positioning time of each measured position. The positioning unit 322 can store the operator position information in the data storage unit 332 of the storage device 33. The sending unit 323 sends the operator position information to the job management device 5. The sending unit 323 can send the operator authentication information, which represents the result of authenticating the operator 3 holding the operator terminal 30, and the operator location information to the job management device 5 accordingly.

[0046] The storage device 33 includes a program storage unit 331 and a data storage unit 332.

[0049] Under the control of the authentication unit 321, the authentication device 36 authenticates the operator 3 through authentication methods such as facial authentication, fingerprint authentication, voice authentication, and password input.

[0050] The positioning device 37 determines the position of the operator 3 under the control of the positioning unit 322. The positioning device 37 can determine the position of the operator 3 using GNSS or the like.

Figure 8 In this example, the touch panel 651 displays a map 91 showing the area including field 9, and a table 92 showing the working devices 2 and workers 3 within the area of ​​the map 91. Figure 8 As shown, the touch panel 651 can display a work device icon 72 representing the work device 2 at a location on the map 91 corresponding to the location of the work device 2, overlapping with the map 91. Additionally, the touch panel 651 can display a worker icon 73 representing the worker 3 at a location on the map 91 corresponding to the location of the worker 3, overlapping with the map 91. Here, the distance between the work device 2 represented by the work device 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 device icon 72 and the worker icon 73 are displayed respectively.

The work device icon 72 may also include a details display image 724. The positional relationship between the position display image 721, the type display image 722, and the status display image 723 can be fixed. Furthermore, when displaying the details display image 724, the positional relationship of the details display image 724 relative to the position display image 721, the type display image 722, and the status display image 723 can be fixed.

[0090] Location display image 721 shows the location on map 91 of the latest work device location information for work device 2, represented by work device icon 72. Figure 9 In the example, the shape of the location display image 721 includes a downward-facing triangle, the downward-facing vertex of which represents the location of the working device 2 on the map 91.

[0091] The type display image 722 indicates the type of working device 2 represented by the working device icon 72. In Figure 9 In the example, image 722 shows that the working device 2 is a tractor.

[0092] The status display image 723 indicates the status of the working device 2 represented by the working device icon 72. As an example, the status display image 723 can display the first state where the working device 2 is stopped and the second state where the working device 2 is moving in a way that makes it easy for the manager to distinguish them based on differences in color, pattern, shape, etc.

[0093] The detailed display image 724 shows 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, 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, etc. The detailed display image 724 can be temporarily displayed when desired by the manager. For example, it can be displayed by the manager... Figure 8 The touch panel 651 can be operated to switch the display and non-display of all the operation device icons 72 and detail display images 724 displayed on the touch panel 651 at once. As another example, the administrator can control the display of all operation device icons 72 and detail display images 724 displayed on the touch panel 651.

Figure 7A In step S308, when it is presumed that the working device 2 is not in use, the following can be displayed: Figure 9 Operating device 2.

[0095] like Figure 10 As shown, the operator icon 73 includes a location display image 731, an operator display image 732, and a status display image 733. The operator icon 73 may also include a details display image 734.

Furthermore, when displaying the details display image 734, the positional relationship of the details display image 734 relative to the location display image 731, the operator display image 732, and the status display image 733 can be fixed.

[0096] Location display image 731 shows the location on map 91 of operator 3, represented by operator icon 73, with the latest operator location information. Figure 10 In the example, the shape of the location display image 731 includes a downward-facing triangle, the downward-facing vertex of which represents the location of the operator 3 on map 91.

[0097] The worker display image 732 includes an image of worker 3, identified by worker icon 73. As an example, the worker display image 732 may be a photograph of worker 3's face.

[0098] The status display image 733 represents the status of worker 3, represented by worker icon 73. As an example, the status display image 733 can display a first state where worker 3 is stopped and a second state where worker 3 is moving, in a way that makes it easy for the manager to distinguish them based on differences in color, pattern, shape, etc.

[0099] The detailed display image 734 shows details of worker 3, represented by worker icon 73. For example, the detailed display image 734 includes worker 3's name, the latest location information received from worker 3's worker terminal 30, and the latest positioning time. The detailed display image 734 can be temporarily displayed when desired by the administrator. For example, it can be displayed through the administrator's settings. Figure 8 The touch panel 651 can be operated to switch the display and non-display of the detailed display image 734 of all operator icons 73 displayed on the touch panel 651 at once. As another example, the administrator can control the display of the detailed image 734 of all operator icons 73 displayed on the touch panel 651. Figure 8 The operator can operate the touch panel 651 to switch between displaying and not displaying the detailed display image 734 of the operator icon 73.

[0100] like Figure 11 As shown, the comprehensive icon 74 includes a location display image 721, a category display image 722, a status display image 723, and an operator display image 732. The comprehensive icon 74 may also include a details display image 744. The positional relationship between the location display image 721, the category display image 722, the status display image 723, and the operator display image 732 can be fixed. Furthermore, when the details display image 744 is displayed, the positional relationship of the details display image 744 relative to the location display image 721, the category display image 722, the status display image 723, and the operator display image 732 can be fixed.

[0101] The position of the composite icon 74 displays the image 721, which can be compared with... Figure 9 The position display image 721 included in the illustrated work device icon 72 is the same. The type display image 722 of the comprehensive icon 74 can be the same as... Figure 9 The types of display images 722 included in the illustrated work device icon 72 are the same. The status display image 723 of the comprehensive icon 74 can be the same as... Figure 9 The status display image 723 included in the illustrated work device icon 72 is the same.

[0102] The operator display image 732 included in the composite icon 74 can be combined with... Figure 10The operator display image 732 included in the operator icon 73 is the same. However, the configuration of the operator display image 732 in the composite icon 74 can be moved to other locations in a manner that does not overlap with the type display image 722 of the composite icon 74. Figure 11 In the example, the operator display image 732 included in the composite icon 74 is positioned in the upper right corner of the status display image 723 included in the composite icon 74.

[0103] The detailed display image 724 included in the composite icon 74 represents details of the working device 2 and the operator 3 represented by the composite icon 74. For example, the detailed display image 724 includes the name of the working device 2, the name of the operator 3, and the latest positioning time included in the latest working device location information received from the terminal 20 on the working device 2. The detailed display image 724 can be temporarily displayed when desired by the manager. For example, it can be displayed through the manager's... Figure 8 The touch panel 651 can be operated to switch between displaying and not displaying the detailed display image 744 of all the comprehensive icons 74 displayed on the touch panel 651 at once. As another example, the administrator can control the display of the icons 744 on the touch panel 651. Figure 8 The touch panel 651 displays a comprehensive icon 74, which is operated to switch between displaying and not displaying the detailed display image 744 of the comprehensive icon 74.

[0104] Figure 11 The example shown, icon 74, indicates that work device 2 is being used by operator 3 and is in motion. In this case, the manager can infer that operator 3 is using work device 2 and is currently performing work. As an example, in... Figure 7B In step S311, when it is presumed that the working device 2 is being used by the person closest to the operator, a display can be made. Figure 11 The comprehensive icon is 74. Additionally, in... Figure 7A In step S306, it is presumed that the work device 2 is being used by an operator who is not carrying an operator terminal. Therefore, when it is unclear who is using the work device 2, it is possible to display from Figure 11 The icon 74 in the overall icon set omits the icon for the operator displaying image 732.

[0105] like Figure 12 As shown, the integrated icon 74 can indicate that the work device 2 used by operator 3 is stopped by switching the status display image 723. When the work device 2 used by operator 3 is stopped, the manager can infer that operator 3 is either riding on the work device 2 or resting near the work device 2. As an example, in Figure 7B In step S315, when it is presumed that the nearest worker is resting, it can be displayed. Figure 12The comprehensive icon is 74. Additionally, as another example, in... Figure 7B In step S314, when it is presumed that the last worker is resting, it can also be displayed. Figure 12 The comprehensive icon is 74.

[0106] like Figure 13 As shown, the composite icon 74 indicates that the work device 2 is in automatic driving mode (autonomous mode) by replacing the operator display image 732 with the automatic driving display image 742. Even if the work device 2 is moving but not being used by any operator 3, the manager can infer that the work device is in automatic driving mode. As an example, in Figure 7B In step S307, when it is presumed that the working device 2 is in automatic driving mode, it can be displayed. Figure 13 The comprehensive icon is 74.

[0107] (A variation of the icon display method)

[0108] In the above embodiments, such as Figure 11 As shown, regarding the comprehensive icon 74, the structure is explained as follows: a category display image 722 is arranged in the center, a status display image 723 is arranged around the category display image 722, a position display image 721 is arranged below the status display image 723, and an operator display image 732 is arranged in the upper right corner of the status display image 723. As a variation of this structure, the display can be replaced... Figure 11 The integrated icon 74 shown is used in a way that varies depending on the user's operation. Figure 9 The icon 72 of the working device shown is Figure 10 The worker icon 73 shown is toggled in display. As an example, firstly, in... Figure 6 In step S5, a work device icon 72 and an operator icon 73 are generated; in step S6, only the work device icon 72 is displayed. Then, when in... Figure 6 In step S6, the user operates the working device icon 72. Figure 5 When the input / output device 65 receives the operation, the display unit 622 switches the display of the work device icon 72 to the display of the operator icon 73. Furthermore, when the user operates the operator icon 73 and the input / output device 65 receives the operation, the display unit 622 switches the display of the operator icon 73 back to the work device icon 72. Thereafter, whenever the user operates either the work device icon 72 or the operator icon 73, the display of the work device icon 72 and the operator icon 73 can be switched alternately.

[0109] (A variation of the icon for the working device)

[0110] In the above embodiments, such as Figure 9 As shown, the structure of the work device icon 72, which includes a position display image 721, a category display image 722, and a status display image 723, has been described. As a variation of this structure, the work device icon 72 can integrate either the position display image 721 or either the category display image 722 or the status display image 723. For example, the work device icon 72 can integrate the position display image 721 and the category display image 722, or it can integrate the position display image 721 and the status display image 723. In other words, it can be integrated from... Figure 9 The illustrated work device icon 72 omits either the type display image 722 or the status display image 723. Similarly, it can be seen from... Figure 11 The comprehensive icon 74 shown omits any one of the category display image 722 and the status display image 723.

[0111] (Variations of icons for operating devices and general icons)

[0112] Figure 9 The icon 72 of the working device shown is Figure 11 The integrated icon 74 shown can display some or all of the following images—location display image 721, type display image 722, status display image 723, operator display image 732, and detail display image 724—in any color for each image. By differentiating colors to display various information such as the location of the work device 2, the type of the work device 2, the status of the work device 2, and the details of the operator 3, users can more intuitively identify each icon and image.

[0113] The invention described above, based on the embodiments, has been specifically explained. However, the invention is not limited to these embodiments, and various modifications can be made without departing from its spirit. Furthermore, the features described in the embodiments can be freely combined without technical inconsistencies.
