Description

The present invention relates to a harvester management system and a management method for managing various operations based on a screen display.

In a combine as described in Patent Document 1, various setting screens related to the combine are displayed on the display device, and the settings are made according to the screen display.

For example, in a conventional combine that performs automatic driving, management of automatic driving and creation of an outline map of a field are performed according to screen display. In the screen display, the initial image is displayed first, and various menu selection switches are displayed on the initial image. By selecting the menu selection switch displayed on the initial image, the corresponding operation management image is displayed on the screen. The screen display progresses according to the selection process for each operation management image and various operations under management.

JP-A-2019-126286

However, since the screen display proceeds in order and the management is performed based on the screen display, if the operation management process is interrupted during the management, it may be necessary to redo the management work from the initial image.

For example, if the combine engine is stopped in the middle of the operation management process, the operation management image does not return to the operation management image being processed even if the engine is started, and the operation management process needs to be restarted from the initial image display, which is efficient. It interferes with the work.

In order to solve the above problems, the harvester management system and management method of the present invention aim to efficiently restart the operation management process even if the operation management process is interrupted.

In order to achieve the above object, the management system according to the embodiment of the present invention is a management system that performs an operation management process for managing the work running of the work vehicle using the management image, and displays the management image. A display unit, a display control unit that displays an initial image as the management image and a plurality of operation management images displayed following the initial image on the display unit one by one, and an operation for inputting an operation on the management image. After the reception unit, the setting control unit that generates the setting control signal for setting the operation of the work vehicle in response to the operation on the management image, and the operation management process being interrupted by the power supply being stopped. The interruption detection unit that transmits a detection signal when it detects that the operation management process has been restarted, and the storage unit that stores the information of the operation management image displayed when the operation management process is interrupted. When the display control unit receives the detection signal from the interruption detection unit, the display control unit is displayed between the initial image and the operation management image displayed when the operation management process is interrupted. One of the operation management images that has been used is displayed on the display unit as a restart image.

Generally, when a device (information terminal 17 described later) shuts down due to an engine stop or the like and the operation management process is interrupted, an initial image is displayed when the operation management process is restarted even if the operation management process is in progress. Will be done. Therefore, in order to continue the operation management process, it is necessary to proceed in order from the initial image and display the operation management image that was displayed when the operation management process was interrupted, which is efficient because it takes a lot of man-hours. It was a hindrance to the work.

According to the above configuration, the operation management image displayed between the initial image and the operation management image displayed at the time of interruption is displayed as a restart image without returning to the initial image, and the operation management process can be continued promptly. Can be done. Therefore, the operation management process can be restarted from near the process state at the time of interruption without going through an extra process, and the work can be continuously performed efficiently.

Further, when a system abnormality or the like occurs, an appropriate operation management process cannot be performed, and it may be necessary to interrupt the operation management process inevitably. In such a case, the process corresponding to the operation management image displayed at the time of interruption may not be performed properly, and even if the operation management process is continued, the operation management image displayed at the time of interruption is displayed. It may not be appropriate to continue the operation management process.

According to the above configuration, by displaying the operation management image displayed up to the time of interruption as a restart image, the operation management process performed when the system abnormality occurs is abandoned and before the system abnormality occurs. The operation management process can be continued from the process corresponding to the operation management image. Therefore, appropriate operation management processing can be efficiently and continuously performed.

Further, when the display control unit receives the detection signal from the interruption detection unit, the display control unit displays a selection display for selecting whether to return to the initial image or restart the operation management process, and restarts the operation management process. When is selected, the resumed image may be displayed on the display unit.

With such a configuration, it is possible to select whether to perform the operation management process from the beginning or to continuously restart the operation management process from the state in which the process has already been completed, and appropriate operation management according to the intention of the operator. Processing can be restarted.

For example, if the operation management process is interrupted due to a system abnormality such as a shift in the position of the own vehicle or a failure of the device or management system mounted on the work vehicle, the operation management process is performed after checking the state of the work vehicle or the like. It may be appropriate to decide whether to start over or continue processing from the point of interruption. According to the above configuration, when the operation management process is restarted, a step of seeking the judgment of the operator is included instead of suddenly returning to the middle of the operation management process. Therefore, when the operation management process is restarted, it is possible to obtain an opportunity to confirm whether or not the system abnormality has been resolved, and it is possible to restart the operation management process after it is confirmed that the system abnormality has been resolved. .. Further, depending on the situation, the operation management process can be restarted from the beginning after the system abnormality is resolved, or from the state before the system abnormality occurred. Therefore, it is possible to suppress inappropriate operation management processing due to a system abnormality and perform appropriate operation management processing.

Further, each time the operation management process is interrupted due to the power supply being stopped, the storage unit stores the information of the operation management image being displayed, and the display control unit stores the restart image. Before displaying, a list showing the operation management image corresponding to the information stored in the storage unit is displayed, and the display control unit displays the operation management image selected from the list as the restart image. You may.

With such a configuration, even when the operation management process is continued, it is selected from which operation management image of the operation management images when the operation was interrupted in the past is displayed to restart the operation management process. It is possible to restart the operation management process more appropriately according to the intention of the worker.

Further, the restart image is displayed only when the operation management process is interrupted while performing a predetermined process among the operation management processes, and when a process other than the predetermined process is performed. When the operation management process is interrupted, the initial image may be displayed even if the detection signal is received.

In the operation management process, the initial environment settings may be performed first, and then full-scale operation management may be performed. If the operation management process is interrupted during the operation management, it may be appropriate to skip the environment settings and perform the operation management. On the other hand, if the operation management process is interrupted in the middle of the environment setting, it may be better not to forcibly continue the process from the middle of the environment setting. Further, even in the middle of operation management, it may not be appropriate to continue the processing from the middle of the interrupted processing depending on the content of the processing.

According to the above configuration, the process that should restart the process from the initial screen and the process that should continue the operation management process are distinguished, and the operation management process is continued only in the case of the process that should continue the operation management process. Can be done. Therefore, the operation management process can be performed more efficiently.

Further, the management method according to the embodiment of the present invention is a management method for performing an operation management process for managing the work running of the work vehicle using the management image, and the management image follows the initial image and the initial image. A step of displaying a plurality of operation management images displayed one by one, a step of inputting an operation on the management image, and a setting control signal for setting the operation of the work vehicle according to the operation on the management image. A step of generating, a step of detecting a management restart state in which the operation management process is resumed after the operation management process is interrupted due to the power supply being stopped, and a step of detecting the operation management process when the operation management process is interrupted. When the step of storing the information of the displayed operation management image and the management restart state are detected, the initial image leads to the operation management image displayed when the operation management process is interrupted. It has a step of displaying one of the operation management images displayed up to the above as a restart image.

According to such a configuration, the operation management image displayed between the initial image and the operation management image displayed at the time of interruption is displayed as a restart image without returning to the initial image, and the operation management process is promptly continued. can do. Therefore, the operation management process can be restarted from near the process state at the time of interruption without going through an extra process, and the work can be continuously performed efficiently.

In addition, by displaying the operation management image that was displayed up to the time of interruption as a restart image, the operation management process that was performed when a system error occurred is discarded, and the operation management image before the system error occurs. The operation management process can be continued from the process corresponding to. Therefore, appropriate operation management processing can be efficiently and continuously performed.

Further, when the management restart state is detected, a selection display for selecting whether to return to the initial image or restart the operation management process is displayed, and when it is selected to restart the operation management process, the operation management process is selected. The resumed image may be displayed.

With such a configuration, it is possible to select whether to perform the operation management process from the beginning or to continuously restart the operation management process from the state in which the process has already been completed, and appropriate operation management according to the intention of the operator. Processing can be restarted.

Further, each time the operation management process is interrupted due to the power supply being stopped, there is a step of storing the information of the operation management image being displayed, and the information is stored before displaying the restart image. A list showing the operation management image corresponding to the information may be displayed, and the operation management image selected from the list may be displayed as the restart image.

With such a configuration, even when the operation management process is continued, it is selected from which operation management image of the operation management images when the operation was interrupted in the past is displayed to restart the operation management process. It is possible to restart the operation management process more appropriately according to the intention of the worker.

Further, the restart image is displayed only when the operation management process is interrupted while performing a predetermined process among the operation management processes, and when a process other than the predetermined process is performed. When the operation management process is interrupted, the initial image may be displayed even in the management restart state.

According to such a configuration, the process that should restart the process from the initial screen and the process that should continue the operation management process are distinguished, and the operation management process is continued only in the case of the process that should continue the operation management process. can do.

The threshing device 9 is provided on the left side of the grain tank 7, and threshs the cut grain culms transported from the cutting section 3.

[Automatic driving]
The automatic traveling of the combine will be described with reference to FIG. The combine automatically travels along a travel route set in the field. For this purpose, the position of the own vehicle is required. The own vehicle position detection module 80 includes a satellite navigation module 81 and an inertial navigation module 82. The satellite navigation module 81 receives a GNSS (global navigation satellite system) signal (including a GPS signal) from the artificial satellite GS, and outputs positioning data for calculating the position of the own vehicle. The inertial navigation module 82 incorporates a gyro acceleration sensor and a magnetic compass sensor, and outputs a position vector indicating an instantaneous traveling direction. The inertial navigation module 82 is used to supplement the vehicle position calculation by the satellite navigation module 81. The inertial navigation module 82 may be arranged at a different location from the satellite navigation module 81.

Prior to the automatic running, the driver manually operates the combine and performs a harvesting run so as to orbit along the boundary line of the field in the outer peripheral portion of the field as shown in FIG. If possible, the harvesting run may be carried out so as to orbit along the boundary line of the field by automatic running. As a result, the area that has become the already cut land (already worked area) is set as the outer peripheral area SA. Then, the area left as uncut land (unworked land) inside the outer peripheral area SA is set as the work target area CA. FIG. 3 shows an example of the outer peripheral region SA and the work target region CA.

When the outer peripheral area SA and the work target area CA are set, the traveling route in the work target area CA is calculated. The calculated travel route is sequentially set based on the work travel pattern, and the combine automatically travels along the set travel route. In addition, this combine has a U-turning pattern that changes direction along a U-shaped turning running path, an α-turning pattern that changes direction while repeating forward and backward movement, and reverse running as turning patterns for turning running in automatic driving. Therefore, it is possible to perform a switchback turning pattern in which the direction is changed in the same manner as the U turning pattern in a region narrower than the U turning pattern.

[Operation management process]
In the combine, various operation management processes such as operation setting processing and operation confirmation processing are performed according to the management image displayed on the information terminal 17. The management image is composed of an initial image displayed when the information terminal 17 is started, and a plurality of operation management images displayed in order following the initial image. In the management image, an image displaying the combine state according to the processing performed using the management image, an image necessary for setting / confirmation, a switch used for various operations, and the like are displayed. In the present embodiment, as a specific example of the operation management process, a map creation process for creating an outline map of the field will be described.

First, a map creation process for newly creating an outline map of a field will be described with reference to FIG. When the combine engine is started or the power of the information terminal 17 is turned on, the initial image is displayed on the information terminal 17 (FIG. 4A). In the initial image, the selection switch group 31 is displayed in addition to various information. The selection switch group 31 includes a map creation switch for starting the creation of an outline map of the field, an operation assist switch for starting automatic operation, a setting switch for performing various settings, and the like. In this embodiment, the outline map of the field is created, so the map creation switch is selected.

When the map creation switch is selected, the information terminal 17 is operated to select whether to start recording the travel locus 32 and start the map creation process or to continue the previously performed map creation process. The image is displayed (FIG. 4 (b)). In this operation management image, as the selection switch group 31, a recording start switch for starting the map creation process and an interrupt call switch for continuing the map creation process are displayed.

When the recording start switch is selected to start the map creation process, the operation management image related to the map creation process is displayed and the map creation process is started. Along with this, the combine starts running along the outer circumference of the field. An operation management image related to map creation is displayed on the information terminal 17, and the traveling locus 32 of the combine is displayed (FIG. 4 (c)). Then, when the combine goes around the outer circumference of the field, the map creation process is completed (FIG. 4 (d)).

If the combine engine is stopped or the power of the information terminal 17 is turned off during the map creation process, the map creation process is interrupted. When the map creation process is interrupted, the information terminal 17 stores information indicating which operation management image is displayed each time the map creation process is interrupted.

Next, with reference to FIG. 5, a procedure for restarting the map creation process so that the interrupted map creation process is continued will be described.

When the combine engine is started or the power of the information terminal 17 is turned on after the map creation process is interrupted, the information terminal 17 is displayed with a selection to confirm whether or not to restart the map creation. 33 is displayed, and at the same time, “yes” and “no” answer switches are displayed as the selection switch group 31 (FIG. 5 (a)).

When "No" is selected, the initial image is displayed (see FIG. 4A), and the map creation process is restarted from the beginning. If "Yes" is selected, the map creation process continues. At this time, a list 34 for selecting from which operation management image the map creation process is to be restarted is displayed (FIG. 5 (b)).

In the list 34, a display showing the operation management image displayed when the map creation process is interrupted is displayed. For example, Listing 34 shows the date and time when the map creation process was interrupted. If the map creation process has been interrupted multiple times since the map creation process was started, Listing 34 displays a plurality of displays corresponding to the operation management images displayed when the map creation process was interrupted. Will be done.

When any of the displays showing the operation management image displayed at the time of interruption is selected from the list 34, the operation management image displayed from the initial image to the selected operation management image is displayed. Displayed as a resume image. For example, the operation management image displayed immediately before the operation management image displayed at the time of interruption is displayed (FIG. 5 (c)).

Then, the map creation process is restarted according to the displayed restart image, and the combine is run until it goes around the field (FIG. 5 (d)).

As described above, the operation management image displayed between the initial image and the operation management image displayed at the time of interruption is displayed as the restart image without returning to the initial image, so that no extra process is required. , The operation management process can be continued quickly. As a result, the operation management process can be restarted from the restarted image, and the work can be performed efficiently. In addition, since the operation management process can be restarted from the restart image which is a simple selected image, operation mistakes can be reduced as compared with the case where the operation is performed from the initial image, and the work is efficient and easy. It can be performed. Further, when a system abnormality or the like occurs, an appropriate operation management process cannot be performed, and it may be necessary to interrupt the operation management process inevitably. By displaying the operation management image that was displayed up to the time of interruption as a restart image, the operation management process that was performed when a system error occurred is eliminated, and the operation management image before the system error occurs is supported. The operation management process can be continued from the process to be performed. Therefore, appropriate operation management processing can be efficiently performed.

[Control of management image]
Next, the configuration in which the information terminal 17 controls the management image will be described with reference to FIGS. 4 and 5 with reference to FIGS. 6 and 7.

As shown in FIG. 6, the information terminal 17 includes a display unit 40, a display control unit 41, an operation reception unit 42, a setting control unit 43, a storage unit 44, an interruption detection unit 45, and a communication unit 46. The information terminal 17 includes a processor such as an ECU and a CPU. Each functional block constituting the information terminal 17 may be distributed or merged in any configuration.

The combine includes a map generation unit 47, a travel control unit 51, a work control unit 52, and the like. The map generation unit 47, the travel control unit 51, the work control unit 52, and the like perform data communication with the information terminal 17 via the communication unit 46. The map generation unit 47 generates an outline map of the field based on the information received from the information terminal 17. The travel control unit 51 controls the automatic travel of the combine based on the information received from the information terminal 17. The work control unit 52 controls various devices such as the combine harvesting unit 3 (see FIG. 1) based on the information received from the information terminal 17.

The display unit 40 displays a management image such as an initial image or an operation management image. The operation reception unit 42 receives the content of the operation such as the selection of the switch performed during the display of the management image, and delivers it to the display control unit 41 and the setting control unit 43. Under the control of the display control unit 41, the storage unit 44 stores an operation management image, information indicating the operation management image, a state set and managed by the operation management image, and the like. During the operation management process, the interruption detection unit 45 has stopped supplying electric power to the information terminal 17 due to the combine engine being stopped or the power of the information terminal 17 being turned off, and thereafter. It is detected that the power supply has been started again, and a detection signal indicating that the restart of the power supply has been detected is transmitted to the display control unit 41.

The setting control unit 43 receives the contents of operations such as selection of various switches from the operation reception unit 42, and generates a setting control signal for setting the operation of each device of the combine. The setting control unit 43 passes the setting control signal to the communication unit 46.

The display control unit 41 controls the management image or the like displayed on the display unit 40. Hereinafter, a specific control example will be described using the map creation process as an example.

When the information terminal 17 is supplied with power, the display control unit 41 first causes the display unit 40 to display an initial image (corresponding to FIG. 4A / step # 1 in FIG. 7). When "map creation" is selected from the selection switch group 31 displayed in the initial image (step # 2 in FIG. 7), the display control unit 41 receives a signal to that effect from the operation reception unit 42, and the display unit 40 receives a signal to that effect. Display the first operation management image related to the map creation process. In this operation management image, "recording start" and "interrupt call" are displayed as the selection switch group 31 (corresponding to FIG. 4B / step # 3 in FIG. 7). The display control unit 41 not only stores information about the operation management image displayed at the time of interruption, which is stored at the time of interruption of the operation management process, as will be described later, but also every time the operation management image is displayed in this way. In addition, information for identifying the operation management image and information regarding setting / management performed when the operation management image is displayed can be stored in the storage unit 44 (step # 4 in FIG. 7).

The display control unit 41 continues the map creation process until the map creation process is completed while appropriately switching the operation management image based on the operation by the selection switch group 31 displayed on the operation management image (step # in FIG. 7). 5). For example, when "recording start" of the selection switch group 31 is selected, the display control unit 41 starts the map creation process and sequentially displays the necessary operation management images on the display unit 40.

The display control unit 41 confirms whether or not the map creation process is interrupted and restarted while the management image is being displayed. Specifically, when the display control unit 41 receives the detection signal transmitted from the interruption detection unit 45 when the power supply of the information terminal 17 is stopped and then the power supply is started again, the display control unit 41 creates a map. It is determined that the management resumed state in which the process is interrupted and restarted again (step # 6 in FIG. 7). When the display control unit 41 determines that the management is resumed, the display control unit 41 stores the information regarding the operation management image displayed when the map creation process is interrupted in the storage unit 44. Here, the information terminal 17 is connected to two power sources, a power source for operation and a power source for storage. The power supply for operation supplies electric power during normal operation of the information terminal 17, and supplies electric power according to the operating state of the combine engine. The storage power supply is a power supply for storing various information in the storage unit 44 when the operation power supply is cut off. Then, when the power supply of the information terminal 17 is stopped, the power supply for operation is immediately stopped, but the power supply for storage maintains the power supply while the storage unit 44 stores various information. During this time, information and the like related to the operation management image are stored in the storage unit 44.

After that, the display control unit 41 displays an operation management image for confirming whether to continue the map creation process or to restart the map creation process from the beginning. In this operation management image, "recording start" and "interrupt call" are displayed as the selection switch group 31, and this operation management image corresponds to FIG. 4 (b) displayed in step # 3 of FIG. Is the same as (step # 7 in FIG. 7). When the display control unit 41 receives the signal that "recording start" of the selection switch group 31 is selected from the operation reception unit 42, the display control unit 41 restarts the map creation process from the beginning (“No” in step # 7 in FIG. 7). .. On the contrary, in this operation management image, when a signal indicating that "interrupt call" of the selection switch group 31 is selected is received from the operation reception unit 42, it is determined that the map creation process is restarted (continued). (“Yes” in step # 7 of FIG. 7).

When the display control unit 41 determines that the map creation process is restarted (continued), the display control unit 41 does not return to the initial screen, and displays the list 34 for selecting the operation management image displayed at the time of interruption as the operation management image. Display (step # 8 in FIG. 7). In Listing 34, information about the motion management image stored each time the map creation process is interrupted is displayed. Then, the operation management image displayed between the initial image and the operation management image corresponding to the selection in the list 34 is displayed as a restart image, and the map creation process is continued from that state (FIG. 7). Step # 8). When the displayed operation management image is stored, the list 34 is displayed with information indicating the displayed operation management image in addition to the information indicating the operation management image displayed at the time of interruption. Is also good.

[Embodiment 2]
Next, as the second embodiment, a driving assist process for managing automatic driving, which is a specific example of the operation management process, will be described.

First, the driving assist process at the time of performing automatic driving will be described with reference to FIG. When the combine engine is started or the power of the information terminal 17 is turned on, the initial image is displayed on the information terminal 17 (FIG. 8A). In the initial image, the selection switch group 31 is displayed in addition to various information. The selection switch group 31 includes a map creation switch for starting the creation of an outline map of the field, an operation assist switch for starting automatic operation, a setting switch for performing various settings, and the like. Since automatic driving is started in the present embodiment, the driving assist switch is selected.

When the driving assist switch is selected, the information terminal 17 displays an operation management image for selecting the field to be automatically traveled (FIG. 8B). When the field to be automatically driven is selected, an operation management image for making various settings related to the automatic running is displayed (FIG. 8 (c)). Then, when the setting is completed, the automatic driving is started, and the operation management image displaying the driving assist status is displayed (FIG. 8 (d)).

If the combine engine is stopped or the power of the information terminal 17 is turned off during the driving assist processing, the driving assist processing is interrupted. When the driving assist process is interrupted, the information terminal 17 stores information indicating which operation management image is displayed each time the driving assist process is interrupted.

Next, a procedure for resuming the interrupted driving assist process will be described with reference to FIG.

When the combine engine is started or the power of the information terminal 17 is turned on after the driving assist processing is interrupted, the information terminal 17 is informed whether or not to restart the automatic driving (driving assist). The selection display 33 to be confirmed is displayed, and at the same time, the answer switches of “Yes” and “No” are displayed as the selection switch group 31 (FIG. 9A).

When "No" is selected, the initial image is displayed (see FIG. 8A), and the driving assist process is restarted from the beginning. When "Yes" is selected, the driving assist process is continued. At this time, an operation management image (see FIG. 8 (c)) for making various settings related to automatic driving, which is a predetermined restart image as a screen for restarting the driving assist process, is displayed (FIG. 9 (b)). ).

When the setting is completed, the driving assist process is restarted from the position where the automatic driving is interrupted, and an operation management image displaying the status of the driving assist is displayed (FIG. 9 (c)).

As described above, as the motion management image displayed between the initial image and the motion management image displayed at the time of interruption without returning to the initial image, the motion management image for performing various settings related to automatic driving, etc. Since the operation management image predetermined as the operation management image at the time of resumption is displayed as the resumption image, the operation management process can be continued quickly.

In addition, when resuming driving assistance, it may be desired to change the automatic driving setting. When restarting, the display of the operation management image is restarted from the operation management image related to the automatic driving setting, so the driving assist process can be restarted from the automatic driving setting while avoiding the display of the extra operation management image, and it is efficiently automatic. You can drive.

[Another Embodiment]
(1) In the first embodiment, the information terminal 17 does not store information indicating which operation management image is displayed in order each time the operation management image is displayed, and displays the information when the operation management process is interrupted. Only the information indicating the operation management image that has been performed may be stored. Then, as the list 34, only the information indicating the operation management image displayed when the map creation process is interrupted may be displayed.

If any of the operation management images displayed before the interruption is selected from the list 34, the operation management image displayed before the operation management image is displayed when the operation management process is restarted (continued). Instead, the selected operation management image may be displayed as a restart image. As a result, when it is not necessary to check the status of the work vehicle, it is possible to quickly return to the operation management process at the time of interruption, and the operation management process can be continued more efficiently.

(2) In the second embodiment, a plurality of operation management images to be displayed when the driving assist process is continued are prepared, and a list 34 for selecting the prepared operation management images is displayed as in the first embodiment. The selected operation management image may be displayed as a restart image.

As a result, the resumed image can be selected according to the situation, and the operation management process can be continued in a more appropriate state.

(3) In each of the above embodiments, the resumed image may be displayed only when the operation management process is interrupted and then restarted while performing a predetermined process among the operation management processes. Even if the operation management process is interrupted when other processes are being performed, the initial screen is displayed when the operation management process is restarted thereafter. There is an operation management process in which it is inappropriate to display the resumed image when the operation management process is restarted. With the above configuration, the resumed image can be displayed only in the situation where it is appropriate to display the resumed image, and the appropriate operation management process can be continued.

(4) In each of the above embodiments, the operation management process managed by the information terminal 17 can be applied not only to the map creation process and the driving assist process, but also to various operation management processes related to the operation of the work vehicle.

(5) In each of the above embodiments, as the switch for operating the management image, an operation switch 48 provided in the combine operation unit 5 or the like may be used in addition to the selection switch group 31 displayed on the display unit 40. .. The operation switch 48 passes operation information to the display control unit 41 and the setting control unit 43 via the operation reception unit 42. This improves the operability of the operation management process. Further, data transmission / reception between the map generation unit 47, the travel control unit 51, the work control unit 52, and the information terminal 17 may be performed by any means without going through the communication unit 46.

(6) The operation management method described in each of the above embodiments is not limited to the configuration realized by the functional block, and at least a part thereof may be realized by a program. In this case, the program is stored in the storage unit 44 or a storage device provided outside the information terminal 17 capable of data communication with the information terminal 17, and is executed by a processor such as an ECU or CPU mounted on the information terminal 17.

The present invention is not limited to head-feeding combine harvesters, but can be applied to ordinary combine harvesters, other harvesters for harvesting soybeans, corn, etc., and work vehicles for performing various operations.
