The plurality of field selection units 81 can also be selected by touch operation or operation of the operation tool 57, and setting information (setting value) is shown. The set value in the plurality of field selection units 81 is a value indicating the responsiveness when the change cylinder 25a is expanded and contracted, and is, for example, a value of the responsiveness (control gain) of the expansion and contraction operation. In the plurality of field selection units 81, the larger the set value, the higher the responsiveness of the change cylinder 25a (moves sensitively), and the smaller the set value, the lower the responsiveness of the change cylinder 25a (moves insensitively).

The plurality of field selection units 81 are a first field selection unit 81a, a second field selection unit 81b, a third field selection unit 81c, and a fourth field selection unit 81d.

The display device 50B displays the setting input unit 82 on the posture setting screen M5. The setting input unit 82 is a unit for changing (inputting) the set values of the plurality of field selection units 81. The setting input unit 82 has an increase input unit 82a and a decrease input unit 82b. The increase input unit 82a is a portion for increasing the set value in the plurality of field selection units 81.

Specifically, when any of the second field selection unit 81b, the third field selection unit 81c, and the fourth field selection unit 81d is selected and the increase input unit 82a is selected, the selected field selection unit 81 The set value increases. Further, when the reduction input unit 82b is selected with any of the second field selection unit 81b, the third field selection unit 81c, and the fourth field selection unit 81d selected, the set value of the selected field selection unit 81 is set.

Specifically, the increasing input unit 82a of the setting input unit 82 corresponds to the right portion of the tractor 1, and the decreasing input unit 82b corresponds to the left portion of the tractor 1. In other words, the increasing input unit 82a corresponds to the right part of the working device 2, and the decreasing input unit 82b corresponds to the left part of the working device 2.

The display device 50B displays the operation display unit 83 on the posture setting screen M5. The operation display unit 83 is provided corresponding to the setting input unit 82 and changes the display of the operation mode of the posture changing device 25 based on the state of the tractor 1. The operation display unit 83 changes the display based on the operation mode calculated by the arithmetic unit. In this embodiment, the arithmetic unit is also used as the control device 40. The arithmetic unit and the control unit 40 may be separate.

Hereinafter, assuming that the arithmetic unit is also used as the control device 40, the arithmetic of the operation mode and the display of the operation mode will be described.
The control device 40 (arithmetic unit) calculates the operation mode based on the detection value of the tilt detection device 41k, which is one of the detection devices 41. The tilt detecting device 41k is provided on the machine body 3 and detects the tilt of the machine body 3 with respect to the horizontal direction. The control device 40 (arithmetic unit) calculates the operation mode of the posture changing device 25 when the posture changing device 25 is operated in a state where the tilt is detected by the tilt detecting device 41k. That is, in the state where the control device 40 (arithmetic unit) has the tilt detected by the tilt detection device 41k, either the extension or the contraction of the change cylinder 25a when the tilt of the work device 2 is changed in a predetermined direction. The direction is obtained as the operation mode.

As shown in FIG. 13A, when the right portion of the tractor 1 is lower than the left portion of the tractor 1, the right portion of the working device 2 is also lower than the left portion. Here, when the working device 2 is maintained horizontally in the horizontal mode, the changing cylinder 25a of the posture changing device 25 is contracted and the right portion of the working device 2 is raised. As shown in FIG. 13A, when the tilt detection device 41k detects that the right portion of the tractor 1 is downward (downward to the right) and the horizontal mode is set, the control device 40 (arithmetic unit) changes cylinder. The operation mode in the direction of contracting 25a is obtained.

Therefore, the control device 40 has a "contraction" indicating that the change cylinder 25a is contracted to the operation display unit 83 on the increase input unit 82a side corresponding to the right portion of the tractor 1 (working device 2), that is, the direction of contraction. "Shrink" indicating is displayed. Further, the control device 40 causes the operation display unit 83 on the reducing force unit 82b side corresponding to the left portion of the tractor 1 (working device 2) to display "extension" which is the opposite of "contraction" of the change cylinder 25a. ..

Further, as shown in FIG. 13B, when the left portion of the tractor 1 (working device 2) is lower than the right portion of the tractor 1 (working device 2) and the horizontal mode is set, the posture changing device 25 The change cylinder 25a is extended to raise the left portion of the working device 2. As shown in FIG. 13B, when the tilt detection device 41k detects that the left portion of the tractor 1 (working device 2) is downward (downward to the left) and the horizontal mode is set, the control device 40 (arithmetic unit) is set. ) Obtains an operation mode in the direction of extending the change cylinder 25a.

Therefore, the control device 40 causes the operation display unit 83 on the reduction input unit 82b side to display "extension" indicating that the change cylinder 25a is extended, that is, "extension" indicating the extension direction. Further, the control device 40 causes the operation display unit 83 on the increase input unit 82a side corresponding to the right part of the tractor 1 (working device 2) to display "contraction" which is the opposite of "extension" of the change cylinder 25a. .. That is, as described above, the operation display unit 83 switches the direction of expansion or contraction according to the inclination of the tractor 1 to display.

By the way, the setting input unit 82 may change the display position to be displayed on the posture setting screen M5 according to the state of the tractor 1. As shown in FIG. 14A, when the tractor 1 descends to the right, the display position of the increase input unit 82a corresponding to the right portion of the tractor 1 is positioned below the decrease input unit 82b corresponding to the left portion of the tractor 1. Let me. Further, as shown in FIG. 14B, when the tractor 1 descends to the left, the display position of the decreasing input unit 82b corresponding to the left portion of the tractor 1 is lower than the increasing input unit 82a corresponding to the right portion of the tractor 1. To be located in. That is, the inclination of the tractor 1 may be indicated by the display position of the setting input unit 82 (increase input unit 82a, decrease input unit 82b) on the posture setting screen M5.

The work machine 1 corresponds to the machine body 3, an operating unit (first operating unit) provided on the machine body 3 and operating based on the setting information, a setting input unit 82 for inputting setting information, and a setting input unit 82. The operation display unit 83 includes a display device 50B provided with an operation display unit 83 for displaying the operation mode of the operation unit, and the operation display unit 83 changes the operation mode to be displayed based on the state of the machine body 3. According to this, since the operation mode of the work display unit 83 provided corresponding to the setting input unit 82 changes based on the state of the machine body 3, the operation when inputting the setting information to the setting input unit 82 The aspect can be easily grasped.

The work machine 1 includes a tilt detection device 41k that detects the tilt of the machine 3 as a state of the machine 3, and an arithmetic unit (control device 40) that calculates an operation mode based on the tilt detected by the tilt detection device 41k. , Is equipped. According to this, for example, in a situation where the machine body 3 is tilted, it is possible to easily grasp the operation mode of the operation unit when the setting information is input.
The working machine 1 includes a working device 2 connected to the machine body 3, an operating unit has a posture changing device 25 capable of changing the tilt of the working device 2, and an arithmetic unit (control device 40) is a tilt detecting device. The operation mode of the posture changing device 25 when the posture changing device 25 is operated in the state of the inclination detected by 41k is calculated. According to this, for example, in a situation where the machine body 3 is tilted, it is possible to grasp the movement of the posture changing device 25 when the setting information of the posture changing device 25 is changed.

The attitude changing device 25 has at least a hydraulic cylinder (changing cylinder 25a) that changes the inclination of the working device 2 with respect to the machine body 3, and the arithmetic unit (control device 40) has an inclination detected by the inclination detecting device 41k. Therefore, either the extension or contraction of the hydraulic cylinder (change cylinder 25a) when the inclination of the work device 2 is changed to a predetermined direction is obtained as the operation mode. According to this, when the setting information is changed in a situation where the machine body 3 is tilted, it is possible to easily grasp whether the hydraulic cylinder (change cylinder 25a) extends in the extension direction or the contraction direction. Can be done.

The display device 50B changes the display mode of either the setting input unit 82 or the operation display unit 83 according to the inclination of the machine body 3.
The setting input unit 82 includes an increasing input unit 82a for increasing the set value which is setting information and a decreasing input unit 82b for decreasing the set value, and the display device 50B includes an increasing input unit 82a and a decreasing input unit 82b. The position is changed according to the inclination of the machine body 3. According to this, not only the increase or decrease of the set value can be easily increased or decreased by the increase input unit 82a and the decrease input unit 82b, but also by observing the positions of the increase input unit 82a and the decrease input unit 82b displayed on the display device 50. The tilted state of the aircraft 3 can be easily grasped.

The setting input unit 82 includes an increase input unit 82a for increasing the set value which is the setting information and a decrease input unit 82b for decreasing the set value, and the operation display unit 83 inputs the set value to the increase input unit 82a. The operation mode in the case and the operation mode in the case where the set value is input to the reduction input unit 82b are switched and displayed. According to this, not only the increase or decrease of the set value can be easily increased by the increase input unit 82a and the decrease input unit 82b, but also the tilted state of the machine body 3 can be checked by looking at the operation display unit 83 displayed on the display device 50. It's easy to figure out.

By the way, the tractor 1 can automatically raise the working device 2 connected to the tractor 1 when the tractor 1 moves backward. For example, when the speed sensor 41 detects the reverse movement of the tractor 1 (airframe 3), the control device 40 outputs a control signal to the control valve 34 to raise the elevating device 8.
As shown in FIG. 15, when a predetermined operation is performed on the display device 50B, the display device 50B displays the ascending setting screen (sixth screen) M6. The ascending setting screen M6 is a screen for setting conditions for automatically ascending the elevating device 8.

The display device 50B displays the condition input unit 90 on the ascending setting screen M6. The condition input unit 90 is a part for inputting a condition for automatically shifting to the ascending operation (automatic ascending operation) after the tractor 1 (airframe 3) moves backward. More specifically, the condition input unit 90 is a portion for inputting a timing (backup timing) for starting the automatic ascending operation after the tractor 1 starts moving backward.

The condition input unit 90 includes a button input unit 91, a slide input unit 92, and a numerical value display unit 93. The button input unit 91 is a portion for inputting a condition by a pressing operation, and includes an increasing input unit 91a for increasing the condition setting value indicating the condition and a decreasing input unit 91b for decreasing the condition setting value. The slide input unit 92 is a portion for inputting conditions by operating the slide, and includes a scale unit 92a and an index unit 92b.

The scale portion 92a is a scale indicating the magnitude of the condition setting value in the setting information, and is configured by, for example, arranging a plurality of vertical bars (gauges) in the horizontal direction. In the scale portion 92a, one side of the vertical bar in the parallel direction, for example, the left side is the minimum value, and the other side in the parallel direction, for example, the right side is the maximum value. The index unit 92b is a portion that indicates the condition setting value with respect to the scale unit 92a, and can be moved along the parallel direction of the vertical bars. The index unit 92b can be moved along the scale unit 92a by a touch operation or the like. Further, the index unit 92b moves along the scale unit 92a in conjunction with the condition setting value input by the button input unit 91. For example, when the condition setting value is increased by the increase input unit 91a, the index unit 92b moves in the increasing direction along the scale unit 92a. Further, when the condition setting value is reduced by the reduction input unit 91b, the index unit 92b moves in the decreasing direction along the scale unit 92a. The numerical display unit 93 displays the condition setting values set by the button input unit 91 and the slide input unit 92 as numerical values.

The condition setting unit 90 has a unit setting unit 94 for setting a unit of the condition setting value. The unit setting unit 94 has a distance setting unit 94a that sets a condition setting value as a distance, and a time setting unit 94b that sets a condition setting value as a time. The distance setting unit 94a and the time setting unit 94b can be selected by touch operation or operation of the operation tool 57. When the distance setting unit 94a is selected, the condition setting value becomes the distance and the time setting unit 94b selects. If so, the condition setting value becomes the time. For example, when either the button input unit 91 or the slide input unit 92 is operated with the time setting unit 94b selected, the condition setting value is the time from when the aircraft 3 moves backward to when the automatic ascending operation is started (ascending). Start time) is set. Further, when either the button input unit 91 or the slide input unit 92 is operated with the distance setting unit 94a selected, the condition setting value is the distance (ascending) from the reverse movement of the aircraft 3 to the start of the automatic ascending operation. It is set as the start distance).

That is, the input setting unit 90 has a distance input unit 95 for inputting the ascending start distance and a time input unit 96 for inputting the ascending start time. In other words, when the distance setting unit 94a is selected, the button input unit 91, the slide input unit 92, and the numerical display unit 93 are switched to the distance input unit 95, and when the time setting unit 94b is selected, the button input is performed. The unit 91, the slide input unit 92, and the numerical value display unit 93 are switched to the time input unit 96.

For example, if the ascending start distance is set to "3.0 m" by the input setting unit 90, when the tractor 1 (airframe 3) reaches a position 3.0 m ahead of the starting position where the reverse movement is started, the elevating device 8 will be used. The working device 2 can be automatically raised from the current position. Further, when the ascending start time is set to "3.0 seconds" by the input setting unit 90, the working device 2 is moved to the current position by the elevating device 8 when 3.0 seconds have elapsed from the start time when the tractor 1 starts moving backward. Can be raised automatically from.

Further, the display device 50B displays the steering angle input unit 100 on the ascending setting screen M6. The steering angle input unit 100 is a portion for inputting a steering angle as a condition for the elevating device 8 to shift to the automatic ascending operation. On the climb setting screen M6, the steering angle input unit 100 is located in a region different from the input setting unit 90.
The steering angle input unit 100 includes a button input unit 101, a slide input unit 102, and a numerical value display unit 103. The button input unit 101 is a portion for inputting a steering angle (set steering angle) by a pressing operation, and includes an increasing input unit 101a for increasing the set steering angle and a decreasing input unit 101b for decreasing the set steering angle. There is. The slide input unit 102 is a unit for inputting a set steering angle by operating the slide, and includes a scale unit 102a and an index unit 102b.

The scale portion 102a is a scale indicating the magnitude of the set steering angle in the setting information, and is configured by, for example, arranging a plurality of vertical bars (gauges) in the horizontal direction. In the scale portion 102a, one side of the vertical bar in the parallel direction, for example, the left side is the minimum value, and the other side in the parallel direction, for example, the right side is the maximum value. The index unit 102b is a portion that points to the set steering angle with respect to the scale unit 102a, and can move along the parallel direction of the vertical bars. The index unit 102b can be moved along the scale unit 102a by a touch operation or the like. Further, the index unit 102b moves along the scale unit 102a in conjunction with the set steering angle input by the button input unit 101. For example, when the set steering angle is increased by the increase input unit 101a, the index unit 102b moves in the increasing direction along the scale unit 102a. Further, when the set steering angle is reduced by the reduction input unit 101b, the index unit 102b moves in the decreasing direction along the scale unit 102a. The numerical display unit 103 displays the set steering angle set by the button input unit 101 and the slide input unit 102 numerically.

For example, if the set steering angle is set to "15 degrees (deg)" by the steering angle input unit 100, when the steering angle of the tractor 1 (airframe 3) becomes equal to or larger than the set steering angle, the work device 2 is operated by the elevating device 8. Can be automatically raised from the current position.
Further, the display device 50B displays the switching unit 105 on the ascending setting screen M6. It is a part for switching the automatic ascending operation of the elevating device 8 between valid and invalid, and is composed of a figure indicating a switch. The switching unit 105 can be switched to ON or OFF by an operation, and when it is ON, the automatic ascending operation is set to be valid, and when it is OFF, the automatic ascending operation is set to be invalid.

The switching unit 105 has a first switch 105a for switching between valid and invalid automatic ascending operation (first automatic ascending operation) performed based on the condition set value, and an automatic ascending operation (second automatic ascending operation) performed based on the set steering angle. It includes a second switch 105b that switches the ascending operation) valid or invalid.
The first switch 105a can be switched on / off by sliding a figure such as an icon (symbol) on the ascending setting screen M6, and the first automatic ascending operation is effective when the first switch 105a is ON. When switched to, the distance input unit 95 and the time input unit 96 are in an active state in which input can be accepted. In the active state, the condition setting value can be input by the button input unit 91 and the slide input unit 92, and the condition setting value can be input (changed) by operating the increase input unit 91a and the decrease input unit 91b. The condition setting value can be input (changed) by sliding the index unit 92b.

On the other hand, when the first switch 105a is OFF and the first automatic climbing operation is disabled, the distance input unit 95 and the time input unit 96 are in an inactive state in which input cannot be received. In the inactive state, the button input unit 91 and the slide input unit 92 cannot input the condition setting value, the increase input unit 91a and the decrease input unit 91b cannot be operated, and the index unit 92b slides. I can't.

Further, the second switch 105b can also be switched on / off by sliding a figure such as an icon (symbol) on the ascending setting screen M6, and the second switch 105b is ON and the second automatic ascending operation is performed. When is effectively switched, the steering angle input unit 100 is in an active state in which input can be received. In the active state, the set steering angle can be input by the button input unit 101 and the slide input unit 102, and the set steering angle can be input (changed) by operating the increase input unit 101a and the decrease input unit 101b. The set steering angle can be input (changed) by sliding the index unit 102b.

On the other hand, when the second switch 105b is OFF and the second automatic ascending operation is disabled, the steering angle input unit 100 is in an inactive state in which input cannot be received. In the inactive state, the button input unit 101 and the slide input unit 102 cannot input the set steering angle, the increase input unit 101a and the decrease input unit 101b cannot be operated, and the index unit 102b slides. I can't.

It should be noted that the past condition setting value may be displayed on the ascending setting screen M6. As shown in FIG. 31, for example, the index unit 92b1 indicates the current condition setting value to the scale unit 92a, and the index unit 92b2 indicates the past condition setting value to the scale unit 92a. The display of the past condition setting value is not limited to FIG. 31, and may be displayed as a numerical value or may be displayed by another method. According to this, when the condition is set, the worker or the like can confirm how the past condition setting value was.

Now, the operating tool 57 capable of operating the display device 50B can operate other display devices. For example, the operating tool 57 can operate the display device 50A and the display device 50C. That is, the operating tool 57 can operate a plurality of display devices 50 (display devices 50A, 50B, 50C). The display device 50 that can be operated by the operating tool 57 is not limited to the display devices 50A, 50B, and 50C described above, and may be, for example, the display device 50 provided in the tractor 1.

Based on the operating state of the tractor 1, the control device 40 determines a target display device, which is a display device 50 that can be operated by the operation tool 57, from among the plurality of display devices 50, and determines an operation signal (operation information) of the operation tool 57. ) Is output to the target display device to execute the operation of the target display device by the operation tool 57. Specifically, as shown in FIG. 23, first, the control device 40 acquires either the detection information detected by the detection device 41 or the operation information of the operation member 42 (S1). The control device 40 grasps the operating state of the tractor 1 based on either the acquired detection information or the operation information (S2). When the control device 40 grasps the operating state of the tractor 1, the control device 40 determines as the target display device the display device that gives the highest priority to the operation from the plurality of display devices 50 based on the operating state (S3). When the control device 40 acquires the operation signal (operation information) of the operation tool 57 after the target display device is determined, the control device 40 outputs the operation information to the target display device, so that the operation tool 57 can be used to display the plurality of display devices 50. The target display device, which is a predetermined display device, is operated from the inside (S4). When the control device 40 changes the target display device for which the operation is prioritized due to a change in the operating state of the tractor 1 during or after the operation by the operation tool 57, the control device 40 is an operation tool for the target display device before the change. The operation of 57 is stopped, and the operation of the operation tool 57 with respect to the changed target display device is started (S5).

FIG. 24 is a diagram showing a flow in which a predetermined display device (target display device) is determined from a plurality of display devices 50 by the control device 40 and the operation of the operation tool 57 is executed.
As shown in FIG. 24, when the ignition switch 42b is turned on and the operating state of the tractor 1 shifts from the drive stop to the drive start process (S10), the control device 50 sets the display device (authentication display device) 50C. The target display device that gives priority to the operation is determined (S11). Further, the control device 40 sets the operation tool 57 as an input device for inputting authentication information (S12), and shifts to the authentication information input process (S13).

In the input process, the control device 40 outputs a command for inputting authentication information to the authentication display device 50C, and the authentication display device 50C displays authentication information such as a password that can be input (S13-1). Further, when the control device 40 accepts the rotation operation by the operation tool 57, it instructs the authentication display device 50C to change the input digit for inputting the authentication information (S13-2). After the input digit is determined, when the control device 40 accepts the rotation operation by the operation tool 57, the control device 40 instructs the authentication display device 50C to change the number to be input to the input digit (S13-3). When the input of the authentication information is received by repeating S13-2 and S13-3, the control device 40 receives the authentication information input by the operation tool 57 (input device) (authentication information displayed on the authentication display device 50C). Is retained as input authentication information (S13-4).

The control device 40 authenticates the stored authentication information and the input authentication information stored in advance, and when the authentication is established (S14, Yes), permits the start of the prime mover 4 and starts the prime mover 4 (S15). .. Further, the control device 40 cancels the priority of the operation for the authentication display device 50C (S16) together with the permission to start the prime mover 4, and determines the display device (terminal display device) 50B as the target display device for which the operation is prioritized. (S17). On the other hand, when the authentication is unsuccessful (S14, No), the control device 40 does not permit the start of the prime mover 4 (permits the start of the prime mover 4), and keeps the prime mover 4 in the stopped state (S18). ). Further, when the start of the prime mover 4 is not permitted, the control device 40 does not release the priority of the operation for the display device 50C, and returns to the input process (S13) again.

After the terminal display device 50B is determined as the target display device, the control device 40 outputs the operation signal of the operation tool 57 to the terminal display device 50B so that the display device 50B can be operated by the operation tool 57 (. S19).
The control device 40 monitors the disconnection in the connection path between the operation tool 57 and the control device 40, or the removal of the terminal display device 50B (S20). When either the wire is disconnected or the terminal display device 50B is removed (S20, Yes), the control device 40 switches the information displayed on the terminal display device 50B to the authentication display device 50C (S21). In other words, the control device 40 switches the display of the authentication display device 50C so that the authentication display device 50C functions as the terminal display device 50B.

In the above-described embodiment, the terminal display device 50B and the authentication display device 50C are switched to the target display device, but the meter display device 50A may be switched to the target display device. Further, among the plurality of display devices 50, the display device 50 set in the target display device may display that the display device 50 can be operated by the operation tool 57. For example, as shown in FIG. 25, when the terminal display device 50B is set as the target display device, the character unit 150 and the mark unit 151 indicate that the terminal display device 50B is a “display device 50 that can be operated by the operation tool 57”. do.

Further, the control device 40 may determine the target display device based on the operation availability information indicating whether or not the operation is possible transmitted from the plurality of display devices 50 in addition to the operation information. As shown in FIG. 23, the control device 40 periodically or irregularly acquires the operability information 152 from the plurality of display devices 50 (S6). For example, when it is indicated that the operability information transmitted from the display devices 50A and 50C is "operable" and the operability information transmitted from the display device 50B is "operable", control is performed. The device 40 sets the display device 50B as the target display device. Further, when the operability information transmitted from the display devices 50A, 50B, and 50C indicates that the operation is not possible, the control device 40 does not set the target display device, and the display device 57 is used for the display device 57. Do not allow 50 operations.

Of the plurality of operating members 42 provided around the driver's seat 10, a predetermined operating member 42 may be set as an operating tool 57 for operating the display device 50. As shown in FIG. 32A, for example, when a predetermined operation is performed, the display device 50B displays the operation setting screen M20 for setting the operation tool 57. On the operation setting screen M20, a list of a plurality of operation members 42 (for example, a PTO shift lever, a shift lever, an upper limit setting dial, etc.) is displayed, and the operation member 42 selected as the operation tool 57 from the list is selected. The designated selection unit 201 is displayed. On the operation setting screen M20, the operation member 42 set by the selection unit 201 is set in the operation tool 57.

Further, in the plurality of display devices 50, the priority of operation by the operation tool 57 may be set. As shown in FIG. 32B, for example, when a predetermined operation is performed, the display device 50B displays the order setting screen M21 for setting the priority of the display device 50. On the order setting screen M21, a list of a plurality of display devices 50 (for example, a meter panel, a terminal, an authentication monitor, etc.) is displayed, and an input unit 202 for inputting a priority is displayed. On the order setting screen M21, the display device 50 can be operated based on the priority input input to the input unit 202. When the priority of the display device 50 is set on the order setting screen M21, the operations by the operation tool 57 are executed in order. For example, when the operation to the display device 50 having the highest priority is completed, the operation of the display device 50 having the next highest priority can be performed.

Can be done.

The control device 40 determines the terminal display device 50B as the target display device when the authentication of the authentication information input to the input device is established, and sets the authentication display device 50C as the target display device when the authentication is not established. According to this, after the authentication is established, the operation tool 57 for inputting the authentication information can be used as the operation tool of the terminal display device 50B.
Now, the tractor 1 can be driven (operated) based on the priority value of the predetermined priority item.

As shown in FIG. 26, when a predetermined operation is performed on the display device 50B, the display device 50B displays the priority setting screen (12th screen) M12.
The display device 50B has priority values (first priority value, second priority value, third priority value) of three priority items (first priority item, second priority item, third priority item) on the priority setting screen M12. Can be set. The priority value is a value indicating the strength with which the driving is prioritized when driving the tractor 1, etc., and the higher the priority value is, the more preferentially the driving based on the priority item is executed, and the lower the priority value is. The drive based on the priority item is not so prioritized.

The display device 50B displays the area display unit 160 on the priority setting screen M12. The area display unit 160 is a part that displays the setting area Q10 for setting the priority value. The setting area Q10 is an area for setting the first priority value of the first priority item, the second priority value of the second priority item, and the third priority value of the third priority item. In the setting area Q10, a position indicating the first priority value (coordinates x, y), a position indicating the second priority value (coordinates x, y), and a position indicating the third priority value (coordinates x, y) Is preset. Specifically, the setting area Q10 is a two-dimensional area indicating a priority value, and a reference point (origin) O1 having a priority value of zero is set in the area.

The second scale portion 162a indicates the magnitude of the second priority value in 1 to 5 stages.

The third axis display unit 163 is an axis corresponding to the third priority item, and extends in a direction different from that of the first axis display unit 161 and the second axis display unit 162. The third axis display unit 163 extends downward to the lower left from the reference point O1, for example. The third axis display unit 163 includes a third scale unit 163a indicating a third priority value of the third priority item. The third scale portion 163a is a portion showing a third priority value according to the distance from the reference point O1, for example, the reference point O1 is set to the minimum value and is the position farthest from the reference point O1, that is, In the third axis display unit 163, the third end portion 163b, which is the end portion on the opposite side of the reference point O1, is set to the maximum value. The third scale portion 163a indicates the magnitude of the third priority value in 1 to 5 stages.

Therefore, in the setting area Q10, when the position corresponding to the first scale portion 161a of the first axis display unit 161 and the position corresponding to the second scale portion 161b of the second axis display unit 162 are selected, the first A priority value and a second priority value can be set. Further, in the setting area Q10, when the position corresponding to the first scale portion 161a of the first axis display unit 161 and the position corresponding to the third scale portion 163b of the third axis display unit 163 are selected, the first A priority value and a third priority value can be set.

As described above, when the priority value is set, the marker display unit 165 is displayed in the setting area Q10. The marker display unit 165 has at least two values (first priority value and second priority value, first priority value and third priority value, second priority value) of the first priority value, the second priority value, and the third priority value. And the third priority value).
Hereinafter, the display of the marker display unit 165 will be described in detail together with the configuration of the setting area Q10.

In the setting area Q10, the first end portion 161b of the first axis display unit 161, the second end portion 162b of the second axis display unit 162, and the third end portion 163b of the third axis display unit 163 are linear. It is a triangle formed by connecting with a line L100. The length of the first axis display unit 161 (the length from the reference point O1 to the first end portion 161b) and the length of the second axis display unit 162 (the length from the reference point O1 to the second end portion 162b). The length of the third axis display unit 163 (the length from the reference point O1 to the second end portion 162b) is set to be the same. The opening angle θ1 between the first axis display unit 161 and the second axis display unit 162, the opening angle θ2 between the first axis display unit 161 and the third axis display unit 163, the second axis display unit 162 and the third axis display unit 163. The opening angle θ3 of is a predetermined angle, and is set to, for example, 120 deg. As a result, the setting area Q10 is an equilateral triangle.

When the setting button 195 displayed on the priority setting screen M12 is selected on the display device 50B, the length of the first axis display unit 161, the length of the second axis display unit 162, and the length of the third axis display unit 163 are selected. The window portion for changing the size or the window portion for changing the opening angles θ1 to θ3 is displayed. The shape of the setting area Q10 can be changed by changing the lengths of the first axis display unit 161 and the second axis display unit 162 and the third axis display unit 163, and by changing the opening angles θ1 to θ3. Further, the shape of the line L100 connecting the first end portion 161b, the second end portion 162b, and the third end portion 163b may be changed to an arbitrary shape such as an arc as shown by a dotted line. According to this, the range of the priority value to be set can be changed by changing the opening angles θ1 to θ3 and the length.

Further, the setting area Q10 includes a divided area 166 divided by the first axis display unit 161 and the second axis display unit 162 and the third axis display unit 163. The divided area 166 is an area corresponding to at least two axis display units among the first axis display unit 161, the second axis display unit 162, and the third axis display unit 163. Specifically, the divided area 166 is any one of the first partial area 166a, the second partial area 166b, and the third partial area 166c. The first partial area 166a is an area divided by the first axis display unit 161 and the second axis display unit 162, and the second partial area 166b is divided by the first axis display unit 161 and the third axis display unit 163. The divided area, the third partial area 166c, is an area divided by the second axis display unit 162 and the third axis display unit 163.

The marker display unit 165 is a marker that displays the priority value set in the partial area 166, and is displayed in the first partial area 166a when the first priority value and the second priority value are set, and the first priority is given. When the value and the third priority value are set, they are displayed in the second partial area 166b, and when the second priority value and the third priority value are set, they are displayed in the third partial area 166c.
Therefore, with the priority setting screen M12 displayed on the display device 50B, any part of the setting area Q10 (first partial area 166a, second partial area 166b, third partial area 166c) can be operated by touch operation. By operating the operation tool 57 to select an arbitrary part of the setting area Q10,
At least two of the first priority value corresponding to the first priority item, the second priority value corresponding to the second priority item, and the third priority value corresponding to the third priority item can be set at the same time. can.

By the way, on the priority setting screen M12, "PTO priority" that gives priority to the rotation of the PTO axis is shown as the first priority item, and "vehicle speed priority" that gives priority to the vehicle speed is shown as the second priority item, and the third As a priority item, "fuel consumption priority" is shown, which gives priority to the fuel consumption consumed when the prime mover 4 is driven. The operating unit (second operating unit) of the prime mover 4 and the transmission 5 is driven based on the first priority value corresponding to PTO priority, the second priority value corresponding to vehicle speed priority, and the third priority value corresponding to fuel consumption priority. Is changed.

The PTO priority indicates that the control for maintaining the rotation of the PTO axis is prioritized. The first scale portion 161a of the first axis display unit 161 indicates a value that gives priority to the PTO rotation speed as the first priority value. The higher the value, the stronger the control for maintaining the PTO rotation speed, and the lower the value. The control to maintain the PTO rotation speed is weakened. For example, when the rotation of the PTO axis (PTO rotation speed) is set to a predetermined rotation speed, the control device 40 maintains the actual PTO rotation speed at the set rotation speed according to the first priority value. Change the strength.

Vehicle speed priority indicates that control for maintaining vehicle speed is prioritized. The second scale portion 162a of the second axis display unit 162 shows a value that gives priority to the vehicle speed as the second priority value. The higher the value, the stronger the control to maintain the vehicle speed, and the lower the value, the more the vehicle speed is maintained. Control is weakened. For example, when the vehicle speed is set to a predetermined rotation speed, the control device 40 changes the strength for maintaining the actual vehicle speed at the set vehicle speed according to the second priority value.

Fuel economy priority indicates that control for maintaining fuel economy is prioritized. The third scale portion 163a of the third axis display unit 163 shows a value that prioritizes the maintenance of fuel consumption as the third priority value. The higher the value, the stronger the control to maintain the fuel consumption, and the lower the value, the higher the vehicle speed. The control to maintain is weakened. For example, when the fuel consumption is set to a predetermined rotation speed, the control device 40 changes the strength for maintaining the actual fuel consumption at the set fuel consumption according to the third priority value.

For example, when the first priority value of the PTO priority is higher than the other second priority value and the third priority value, the control device 40 takes the prime mover rotation speed so that the PTO rotation speed becomes a predetermined predetermined rotation speed. Or keep the PTO rotation speed at a predetermined rotation speed by combining the prime mover rotation speed and the shift stage of the PTO transmission unit 5e3. For example, when the second priority value of vehicle speed priority is higher than the other first priority value and the third priority value, the control device 40 corresponds to the vehicle speed in which the rotation speed of the front axle 21F or the rear axle 21R is predetermined. The shift stage (shift level) of the main transmission unit 5c, the shift stage (shift level) of the auxiliary transmission unit 5d, the prime mover rotation speed, and the like are changed so as to match the rotation speed. To change the shift stage (shift level) of the main transmission 5c, change the angle of the diagonal plate 12 of the hydraulic pump 5c1 and change the number of revolutions output from the hydraulic motor 5c2 to the planetary gear mechanism 5c3 (the hydraulic motor 5c2 itself). Change of the number of rotations, change of the number of rotations in the path input from the hydraulic motor 5c2 to the planetary gear mechanism 5c3), change of the flow rate of hydraulic oil supplied to the hydraulic pump 5c1 (opening of the control valve of the hydraulic circuit of the hydraulic pump 5c1) It can be done by changing the degree).

For example, when the third priority value of fuel consumption priority is higher than the other second priority values and the third priority value, the control device 40 causes the fuel consumption of the prime mover 4 to be equal to or less than a predetermined value. The shift stage (shift level) of the main shift unit 5c, the shift stage (shift level) of the auxiliary shift unit 5d, the prime mover rotation speed, and the like are changed.
The work equipment 1 has an operating unit (second operating unit) that operates based on the first priority value of the first priority item, the second priority value of the second priority item, and the third priority value of the third priority item, and the second operation unit. A display device 50B for setting a 1 priority value, a 2nd priority value, and a 3rd priority value is provided, and the display device 50B sets a setting area Q10 for setting a 1st priority value, a 2nd priority value, and a 3rd priority value. The area display unit 160 to be displayed, the first axis display unit 161 including the first scale unit 161a that passes through the reference point O1 shown in the setting area Q10 and indicates the first priority value according to the distance from the reference point O1, and the reference. From the second axis display unit 162, which includes the second scale unit 162a indicating the second priority value according to the distance from the point O1 and extends in a direction different from the first axis display unit 161 through the reference point O1, and the reference point O1. The third axis display unit 163, which includes the third scale unit 163a indicating the third priority value and extends in a direction different from the second axis display unit 162 through the reference point O1, and the setting area Q10.

That is, the setting unit 155 can exclude the meter display device 50A set in the setting display device in FIG. 28A from the setting display device as shown in FIG. 28B. The authentication setting information set by the setting unit 155 can be stored in the non-volatile storage unit 156 provided in the control device 40.

FIG. 30 is a diagram showing a flow of operations of a plurality of display devices 50 based on authentication of authentication information.
As shown in FIG. 30, when the ignition switch 42b is turned on, the control device 40 refers to the authentication setting information of the storage unit 156 (S30). After referring to the authentication setting information, the control device 40 permits the operation of the display device 50 that is not set in the setting display device, for example, the meter display device 50A (S31). Further, the control device 40 holds the operation of the display device 50 set in the setting display device, for example, the terminal display device 50B, without permission (S32). The authentication display device 50C can be operated regardless of whether or not the authentication is established. Next, the control device 40 shifts to the input process (S13). The input process is the same as S13-1 to S13-4 described above.

The control device 40 authenticates the stored authentication information and the input authentication information stored in advance, and when the authentication is established (S33, Yes), permits the start of the prime mover 4 and starts the prime mover 4 (S34). .. Further, the control device 40 permits the operation of the setting display device (terminal display device 50B) as well as the permission to start the prime mover 4 (S35). For example, the control device 40 outputs a permission signal permitting the operation to the setting display device (terminal display device 50B). Upon receiving the permission signal, the setting display device (terminal display device 50B) receives operation information such as touch operations and operation tools 57, and displays various information on the display unit 55 based on the received operation information. On the other hand, when the authentication is not established (S33, No), the control device 40 does not permit the start of the prime mover 4 and keeps the prime mover 4 in the stopped state (S36). Further, the control device 40 disallows the operation of the setting display device (terminal display device 50B) (S37). For example, the control device 40 outputs a disapproval signal for disallowing the operation to the setting display device (terminal display device 50B). When the setting display device (terminal display device 50B) receives the disapproval signal, it does not accept the touch operation or the operation information such as the operation tool 57, and does not execute the display according to the operation.

When the setting display device (terminal display device 50B) cannot acquire either the permission signal or the disapproval signal, the setting display device (terminal display device 50B) receives an external input such as a touch operation or an operation tool 57. Stop reception. Alternatively, the setting display device (terminal display device 50B) stops operating even if a touch operation or an operation such as an operation tool 57 is performed.
Further, after the authentication is established, the control device 40 continuously transmits the permission signal to the setting display device at predetermined time intervals, and the setting display device can be operated while receiving the permission signal (the setting display device). The operation is accepted), and the operation may be disabled (the operation is not accepted) while the permission signal cannot be received. The control device 40 sets the length for transmitting the permission signal to be about 5 times longer than the length for not transmitting the permission signal.

Further, in FIG. 30, the process of permitting / disallowing the start of the prime mover 4 (theft prevention process) and the process of permitting / disallowing the operation of the setting display device (operation process) are linked, but theft prevention is performed. The process may be performed separately from the operation process. For example, the theft prevention process may be performed after the operation process is performed, or the operation process may be performed after the theft prevention process is performed.
The work machine 1 includes an input device that accepts input of authentication information, a plurality of display devices 50 that display information about the work machine, and a plurality of display devices 50 when authentication of the authentication information input to the input device is established. Among them, a control device 40 that permits the operation of the setting display device, which is the preset display device 50, and disallows the operation of the setting display device when the authentication is not established is provided. According to this, when a plurality of display devices 50 are provided, the display device set in the setting display device can be operated when the authentication is established, and cannot be operated when the authentication is not established. That is, when a plurality of display devices are provided, it is possible to temporarily disable the operation of the setting display device, which is a predetermined display device.

The work machine 1 includes a setting unit 155 for setting a display device to be a setting display device among a plurality of display devices 50. According to this, the setting unit 155 can set any display device among the plurality of display devices 50 as the setting display device that requires authentication.
The setting unit 155 is provided on any one of the plurality of display devices 50 and the control device 40. According to this, the configuration can be simplified as compared with the case where it is provided in other equipment of the working machine 1.

The work machine 1 includes a prime mover 4, and the control device 40 permits the start of the prime mover 4 when the authentication of the authentication information is established, and disallows the start of the prime mover 4 when the authentication is not established. According to this, the permission / non-permission of the operation of the setting display device and the permission / non-permission of the start of the prime mover 4 can be linked.
The control device 40 outputs a permission signal that permits the operation of the setting display device and a disapproval signal that disallows the operation of the setting display device, and the plurality of display devices 50 cannot acquire the permission signal and the disapproval signal. In some cases, we will stop accepting input from the outside. According to this, for example, when the permission signal / disapproval signal cannot be acquired due to a failure such as a disconnection or a communication failure, the plurality of display devices 50 stop accepting input, so that they are operated carelessly at the time of failure. Can be prevented.

The work machine 1 includes an operation tool 57 capable of executing the operation of the plurality of display devices 50, and the setting display device operates based on the operation of the operation tool 57 when the operation is permitted, and the operation is not permitted. Even if the operation tool 57 is operated in a certain case, the operation is stopped. According to this, not only the operation tool 57 can operate the plurality of display devices 50, but also the setting display device can be operated by the operation tool 57 after the authentication is established.

It should be considered that the embodiments disclosed this time are exemplary in all respects and not restrictive. The scope of the present invention is shown by the scope of claims rather than the above description, and is intended to include all modifications within the meaning and scope equivalent to the scope of claims.
