In this state, as shown in the left side of the middle part of FIG. 2, the first touch operation is performed on the selection button section 1310 indicated by “V”, and the state indication indicated by “2” is displayed. A second touch operation is performed on the section 1320. As a result, the state information specified by the first touch (indicated by “VVVVV”) is displayed in the second state display section 1320 from the top indicated by “2”. Further, the band-shaped line 136 having the same form (for example, the same pattern or the same color) as the band-shaped line 136 assigned to the second state display section 1320 from the top is to the right of the selection button section 1310 subjected to the first touch operation. It is given to the lower corner. Accordingly, the link relationship between the selection button section 1310 that is the target of the first touch operation and the state display section 1320 in which the operation information assigned to the selection button section 1310 is displayed can be easily confirmed from the display screen 130. can do.

  In the example illustrated on the right side of the middle stage of FIG. 2, the first touch operation is performed on the selection button section 1310 indicated by “W”, and the second touch operation is performed on the main display area 133. ing. As a result, the state information specified by the first touch (indicated by “WWWWW”) is displayed in the main display area 133. Identification information similar to that of the status display section 1320 may be given to the main display area 133. For example, as shown in FIG. 2, when the second touch operation is performed on the main display area 133, the identification information is displayed on the upper side of the selection button section 1310 on which the first touch operation is performed. As an example, a line different from the belt-like line 136 given to the state display section 1320 may be given. The state information displayed in the main display area 133 includes setting screen information for setting parameters and threshold values related to the state information. For example, when the main display area 133 is touched after touching the selection button section 1310 assigned the work height state information of the work device that can be moved up and down, the work height including the current work height state in the main display area 133 The height setting screen is displayed, and the upper limit height and the lower limit height of the work height can be set through the setting screen.

A band-like line 136 having the same color as the color of the band-like line 136 is given.

  FIG. 8 shows an example of the setting screen displayed in the main display area 133. This setting screen is a state display screen and setting screen for the lifting control of the ground work device 22. In the left half of this screen, a status display icon display area 101, an ascending / descending state display area 102, an ascending / descending speed display area 103, a reverse travel depth display area 104, and a slip amount display area 105 are arranged in this order from the top. An increase / decrease button display area 110 is arranged to the right of the center of the elevation control screen. Further, various switch display areas 120 are arranged at the right end of the elevation control screen.

  In the lifting / lowering status display area 102, a lifting / lowering height display meter 102a in the form of a horizontal bar, an upper limit display symbol 102b, and a work position (cultivation height) symbol 102c are displayed. The left end of the lifting height display meter 102a indicates the descending lift stroke end, and the right end indicates the lifting lift end. The actual height of the ground work device 22 is represented by a solid color. At the same time, a numerical value for indicating the actual height as a percentage of the lifting stroke is displayed on the right side of the lifting height display meter 102a. An upper limit indicator is added to the upper limit display symbol 102b, and this upper limit indicator indicates the upper limit position in the up / down stroke. Next to the upper limit display symbol 102b, a numerical value for indicating the upper limit as a percentage of the lifting stroke is displayed. A numerical value for indicating the work position as a percentage of the lifting stroke is also displayed next to the work position symbol 102c. In addition, an upper limit setting switch 111 for setting an upper limit position is arranged in the increase / decrease button display area 110 side by side with the upper limit display symbols 102b. The upper limit setting switch 111 is a software switch including an upper limit increase switch 111a and an upper limit decrease switch 111b, and the position of the upper limit can be adjusted by touch input to these switches.

  Furthermore, you may add the touch input function which sets an upper limit by touching the raising / lowering status display area 102 with a finger directly. This touch input function may be used instead of the above-described upper limit setting switch 111 or may be used together with the upper limit setting switch 111. Specifically, a touch operation function is activated by touching the upper limit display symbol 102b, and a two-touch configuration in which a position touched on the elevation height display meter 102a is a new upper limit position can be employed. In such a touch operation, since there is a possibility of touching a position below the actual height, the restriction that the upper limit is not set below the actual height according to the present invention is particularly important. Further, instead of the above-described two-touch configuration, a configuration may be adopted in which the upper limit height can be set by shifting laterally (swipe operation) while touching the elevation height display meter 102a.

  Horizontal bar graph-like display meters 103a, 104a, and 105a indicating set values are also arranged in the ascending / descending speed display region 103, the reverse travel depth display region 104, and the slip amount display region 105, respectively. Moreover, the numerical value which shows the setting value in the whole percentage is displayed on the right side of them. Further, increase / decrease switches 113, 114, 115 for adjusting the set values are also arranged.

  An example of the functions of the shortcut button 91 and the increase / decrease dial 90 described above will be described using the setting screen of FIG. Here, one shortcut button 91 (here, temporarily named F1 button) is assigned to the upper limit setting of the ground work apparatus 22, and the other one shortcut button 91 (here temporarily named F2 button) is ground work. It is assumed that the work position (cultivation height) setting of the device 22 is assigned. When the shortcut button 91 that is the F1 button is pressed, the elevation display meter 102a and the upper limit display symbol 102b shown in FIG. 8 are displayed in the main display area 133, instead of the contents that have been displayed so far. . Further, when the increase / decrease dial 90 is turned clockwise, the upper limit position is raised, and when the increase / decrease dial 90 is turned counterclockwise, the upper limit position is lowered. When the F1 button is pressed again, the main display area 133 returns to the original display content. Similarly, when the shortcut button 91, which is the F2 button, is pressed and operated, the main display area 133 changes to the contents displayed up to now, and the elevation height display meter 102a and the tillage height symbol 102c shown in FIG. Is displayed. Further, when the increase / decrease dial 90 is turned clockwise, the tillage height increases, and when the increase / decrease dial 90 is turned counterclockwise, the tillage height decreases. When the F2 button is pressed again, the main display area 133 returns to the original display content. When the equipped ground work device 22 does not have an elevating function, other functions such as a target engine speed setting function can be assigned to the shortcut buttons 91 such as the F1 button and the F2 button. . By reassigning frequently used parameter settings to each shortcut button 91, the setting operation is performed smoothly.

[Another embodiment]
