In the remote control device of Patent Document 1, although an operation such as raising and lowering a work vehicle can be performed by pressing the operation unit, the operation may be instructed only by touching the operation unit with an operator's finger or the like. When the operation of the operation unit is an operation related to traveling, the operation unit must be carefully operated, which is very difficult to use.
Therefore, in view of the above-described problems, the present invention can prevent an instruction due to an inadvertent operation when instructing a traveling operation of a work machine, and can carry out a traveling operation instruction reliably. An object of the present invention is to provide a work machine operation system including a terminal.

The technical means of the present invention for solving this technical problem is characterized by the following points.
The invention according to claim 1 includes an instruction display unit that instructs operation of a work machine and displays information related to the work machine, and the traveling operation tool displayed on the instruction display unit is provided on the instruction display unit. When sliding and moving to a set operation via position, and when sliding to an operation decision position set separately from the operation via position, the traveling operation of the work machine corresponding to the operation decision position is instructed. It is characterized by having a running instruction part.

  In the invention according to claim 2, an initial position of the travel operation tool is set in the instruction display unit at a position different from the operation-via position and the operation determination position, and from the initial position to the operation-via position. A first slide setting unit configured to set the slide of the traveling operation tool in a horizontal direction or a vertical direction, and a slide of the traveling operation tool from the operation via position to the operation determination position. And a second slide setting section that is set in a direction that intersects the moving direction at.

According to a third aspect of the present invention, when the travel operation tool is slid in one direction while the travel operation tool is in the operation determination position, the travel operation tool is automatically returned to the initial position. The travel instructing unit cancels the travel operation designated at the operation determination position when the travel operation tool returns from the operation determination position to the initial position.
In the invention according to claim 4, the instruction display unit includes a forward determination unit for determining a forward movement of the work implement and a reverse determination unit for determining the reverse movement of the work implement at the operation determination position. When the travel operation tool moves to the advance determination unit, the travel instruction unit instructs to advance the work implement, and when the travel operation tool moves to the reverse drive determination unit, The travel instruction unit is configured to instruct the work machine to move backward.

According to a fifth aspect of the present invention, the instruction display unit displays the straight bar in a straight line connecting the forward determination unit and the reverse determination unit, and sets the operation via position on the straight bar. The initial position is set at a position away from the straight bar, and when the traveling operation tool is at the initial position, the traveling instruction unit sets the work implement to neutral.
The invention according to claim 6 indicates that when the operation with the work implement is prioritized over the instruction by the travel instruction unit, the instruction display unit is in a state in which the operation of the work implement is prioritized. It is characterized by that.

  The invention according to claim 7 includes a work machine that performs work, and a portable terminal that includes an instruction display unit that instructs the operation of the work machine and displays information related to the work machine. The travel operation tool displayed on the instruction display unit slides and moves to the operation via position indicated on the instruction display unit, and slides to the operation determination position shown separately from the operation via position. And a travel instruction unit for instructing a travel operation of the work machine corresponding to the operation determination position.

The present invention has the following effects.
According to the first and seventh aspects of the present invention, when a traveling operation is performed by sliding the traveling operation tool displayed on the instruction display unit, the traveling operation tool always passes through the operation via position. If it is not positioned at the operation determination position, the traveling operation is not commanded, so that it is possible to reliably instruct the traveling operation while preventing inadvertent operations.

  According to the invention according to claim 2, the slide of the operating tool for traveling is fixed in one direction in the horizontal direction or the vertical direction from the initial position to the position via operation, and one direction from the position via operation to the operation determination position. It will be fixed in the other direction that intersects. Therefore, in order to issue a command for a traveling operation, first, after an operator performs an action (one action) for moving the traveling operation tool in one direction, an action (two actions) for moving in the other direction is required. Become. Therefore, if the operator who operates the mobile terminal does not consciously operate, the traveling operation is not designated, and the conscious sliding motion of the operator can be reflected in the traveling operation.

According to the third aspect of the present invention, it is possible to return to the initial position with one action from the state in which the traveling operation is specified (the state in which the traveling operation tool is at the operation determination position), and the release of the traveling operation can be quickly performed. It can be carried out.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows an overall view of a work machine operation system.
As shown in FIG. 1, the work machine operation system 1 operates a work machine 2 such as an agricultural machine or a construction machine with a portable terminal (work machine remote control) 3.
Hereinafter, the working machine operation system 1 will be described in detail by taking the operation of the tractor with a portable terminal as an example.

  As shown in FIG. 6, the tractor 2 is configured by mounting an engine 11, a transmission 12, and the like on a traveling vehicle (traveling vehicle body) 10 having front and rear wheels. A three-point link mechanism 13 and the like are provided at the rear portion of the traveling vehicle 10 so as to be lifted and lowered. A working device 14 such as a tilling device, a fertilizer spraying device, a pesticide spraying device, a sowing spraying device, and a harvesting device is detachably attached to the three-point link mechanism 13. In addition, an independently mounted cabin 15 is provided behind the engine 11, and a driver's seat 16 is provided in the cabin 15. A display device 18 that displays various information of the tractor 2 is provided around the driver's seat 16.

As shown in FIG. 1, the tractor 2 includes a control device 20 that controls the tractor 2, and a wireless communication device 21 for wireless communication with the mobile terminal 3.
The control device 20 mainly performs travel control for controlling the travel system of the tractor 2 and work control for controlling the work system of the tractor 2. Specifically, the control device 20 includes, for example, “engine control” for controlling the engine 11, “shift control” for switching the multi-stage shift in the transmission 12, and forward and reverse in the transmission 12. “Forward / backward control” is performed to switch between and. Moreover, the control apparatus 20 performs the raising / lowering control which controls raising / lowering of the three-point link mechanism 13, for example as work control.

  Each control will be described in detail. In the engine control, the control device 20 includes an injector based on control signals such as an accelerator lever operation amount, an accelerator pedal operation amount, a crank position, and a cam position that are input to the control device 20. Control common rails, supply pumps, etc. In this engine control, for example, when the operation amount of the accelerator pedal is lower than the operation amount of the accelerator lever, the engine speed is set to a rotation corresponding to the operation amount of the accelerator lever. On the other hand, when the operation amount of the accelerator pedal is larger than the operation amount of the accelerator lever, the engine speed is set to a rotation corresponding to the operation amount of the accelerator pedal. The accelerator lever and the accelerator pedal are provided around the driver's seat and can be operated while the operator is sitting on the driver's seat. The engine control is not limited to that described above.

  In the shift control, the shift of the transmission 12 is controlled based on the operation of the upshift button, the operation of the downshift button, and the operation position of the shift lever. In this shift control, for example, when a shift up button or a shift down button is operated, the shift stage of the main transmission unit of the transmission 12 is switched. Further, when the shift lever operating position is set to the high speed side [H], the shift of the auxiliary transmission unit of the transmission 12 is switched to the high speed side, and when the operation position of the shift lever is set to the low speed side [L], the sub transmission unit of the transmission 12 is set. Shifts to the low speed side. Similarly to the accelerator lever and the like, the shift up button, the shift down button, and the shift lever accelerator lever are also provided around the driver's seat and can be operated while the operator is sitting on the driver's seat. The shift control is not limited to that described above.

  In the forward / reverse control, the forward / backward device provided in the transmission 12 is controlled based on the operation position of the shuttle lever. For example, when the operating position of the shuttle lever is set to the forward side [F], the forward / reverse device is switched to the forward side, and when the operating position of the shuttle lever is set to the reverse side [R], the forward / backward device is switched to the backward side. A shuttle lever is also provided around the driver's seat and can be operated with the operator sitting in the driver's seat. The forward / reverse control is not limited to that described above.

In the elevation control, the elevation of the three-point link mechanism 13 is controlled based on the operation position of the elevation lever. For example, the three-point link mechanism 13 is raised when the operating position of the lifting lever is raised, and the three-point link mechanism 13 is lowered when the operating position of the lifting lever is lowered.
As described above, by operating the operating tools (accelerator lever, accelerator pedal, shift up button, shift down button, shift lever, shuttle lever, lift lever) provided around the driver's seat of the tractor 2, the tractor 1 Can be activated.

Now, the portable terminal 3 can operate the tractor 2 by performing an operation instruction on the screen of the portable terminal 3. The portable terminal 3 is, for example, a tablet PC or a smartphone having a telephone function and has a wireless communication function, and can perform wireless communication with the wireless communication device 21 mounted on the tractor 2 by the wireless communication function.
The mobile terminal 3 is compact, easy to carry, and includes a touch panel 25 that can perform display and input. That is, the mobile terminal 3 includes a touch panel 25 that can instruct operation of the tractor (work machine) 2 and can display various information regarding the tractor 2. Hereinafter, the screen of the touch panel 25 is referred to as an instruction display unit.

Hereinafter, the portable terminal capable of operating the tractor and the operation of the tractor will be described in detail.
An operation application (Application software) for operating the tractor 2 is stored in a storage unit (nonvolatile memory) 26 provided in the mobile terminal 3. For convenience of explanation, the operation application is referred to as a remote control application.
Specifically, the storage unit 26 of the mobile terminal 3 stores a remote control application for operating the work system of the tractor 2 and a remote control application for operating the travel system of the tractor.

  The remote control application for operating these operating systems and running systems is developed by a manufacturing company that manufactures the tractor 2 and a sales company that sells the tractor in accordance with the specifications of the tractor. A user or the like who owns the tractor 2 can store the remote control app in the storage unit 26 of the mobile terminal 3 by using the mobile terminal 3 owned by the user to access a server storing the remote control app.

When the remote control application for operating the traveling system stored in the mobile terminal 3 is activated, as shown in FIG. 2A, a connection message screen for prompting connection with the tractor 2 is displayed on the instruction display unit 25 of the mobile terminal 3. Is displayed.
Next, when an operator such as a user performs a predetermined connection operation on the instruction display unit 25, connection between the mobile terminal 3 and the tractor 2 (wireless communication device 21) is started.

  When the connection is completed, as shown in FIG. 2B, information for operating the traveling system of the tractor 2 (referred to as a traveling operation) is displayed on the instruction display unit 25 of the portable terminal 3. In the portable terminal 3, the display operation of the instruction display unit 25 is performed by the control unit 27 configured by a traveling remote control application, a CPU, or the like stored in the portable terminal 3. When the connection between the portable terminal 3 and the tractor 2 is established, the operation is switched to the operation by the portable terminal 3, and the operation of the tractor 2 by the portable terminal 3 can be performed.

  As shown in FIG. 2B, the instruction display unit 25 of the mobile terminal 3 mainly includes a traveling operation tool 30 for performing a traveling operation of the tractor 2, and a state of the tractor 2 including characters and graphics. , Symbols, numerical values, and other elements. When the operator touches an element corresponding to the travel operation tool 30 (tap, touch, flick, or drag the travel operation tool 30 on the instruction display unit 25), the travel operation tool 30 operates the mobile terminal 3. Recognizing this, various setting values change according to the operation mode of the travel operation tool 30.

For example, as shown in FIG. 2B, the instruction display unit 25 is instructed to shift the first traveling operation tool (first operation tool) 30 </ b> A for designating forward / reverse travel and the transmission 12. A traveling operating tool (second operating tool) 30B for driving and a traveling operating tool (third operating tool) 30C for instructing the target engine speed of the engine are displayed.
When the first operating tool 30A is slid and moved (sliding operation) on the instruction display unit 25 while being frigged or dragged, the first operating tool 30A is moved to a predetermined position. A forward / backward selection can be made. Further, when the second operating tool 30B is pushed by tapping or touching, the number of shift stages of the tractor 1 can be designated.

When the third operating tool 30C is slid and moved (sliding operation) on the instruction display unit 25 while frigging or dragging, and the third operating tool 30C is moved to a predetermined position, the tractor 1 The engine speed can be specified.
In this way, the traveling operation of the tractor 2 (forward / reverse operation, shift operation, engine speed operation) is performed by the operation modes of the first operation tool 30A, the second operation tool 30B, and the third operation tool 30C. Can do.

The operation mode of each operation tool (the first operation tool 30A, the second operation tool 30B, and the third operation tool 30C), the arrangement with respect to the instruction display unit 25, and the correspondence between each operation tool and the traveling operation operate the portable terminal 3. This is determined according to the dominant hand of the operator (hand on the side operating the mobile terminal 3) or the content of the traveling operation performed on the mobile terminal 3.
Next, the traveling operation by the mobile terminal will be described in more detail.

FIG. 3 shows the state of the instruction display unit when the operator of the mobile terminal is right-handed.
As shown in FIG. 3, the range on the one side in the left-right direction of the instruction display unit 25 (for example, the same right side as the dominant hand) and the lower side is a slide instruction area SA. For example, a slide instruction area SA is located on the right side of the center portion in the width direction (left-right direction) of the instruction display unit 25 and below the center portion in the height direction (vertical direction) of the instruction display unit 25. ing.

As shown in FIG. 4, the slide instruction area SA is a place where the right-handed operator easily holds the thumb of the right hand of the operator when holding the mobile terminal 3. It is also a place that is easy to move up, down, left and right along
The tractor traveling operation includes a tractor forward / reverse operation (forward / reverse operation), a tractor shift operation (shift operation), a tractor engine speed operation (engine rotation operation), and the like. Here, for example, in the cabbage harvesting operation, the work device 14 cuts the cabbage while moving the tractor 2 forward, then stops the tractor 2, harvests the cut cabbage, and moves the tractor 2 forward again. Repeated start and stop. In addition, the tractor 2 is repeatedly started and stopped in harvesting other vegetables.

That is, the forward / reverse operation in the traveling operation of the tractor is an operation with a higher operation frequency than other operations (shift operation, engine speed operation).
On the other hand, looking at the mode of traveling operation on the tractor side, the engine speed operation and the forward / reverse operation often swing the operating tool. For example, the engine speed operation is performed by swinging the accelerator lever back and forth, and the forward / backward operation is performed by swinging the shuttle lever back and forth. As can be seen, both engine speed operation and forward / reverse operation are performed by swinging the accelerator lever and shuttle lever.

Here, even when these operations are performed on the portable terminal 3 (on the instruction display unit 25), it is preferable that the operation can be performed with the same feeling as the swing of the accelerator lever and the swing of the shuttle lever. In the portable terminal 3, the swing of the accelerator lever and the swing of the shuttle lever can be replaced with the slide operation of the traveling operation tool 30.
As described above, in consideration of both the operation frequency (frequency of use of the operation tool) and the operation mode (movement of the operation tool), operations that can be instructed by the instruction display unit 25 (forward / reverse operation, speed change operation, engine speed) It is best to set the “forward / reverse operation” in the operation) to the slide instruction area SA.

  That is, in the instruction display unit 25 of the portable terminal 3, the slide instruction area SA that instructs the traveling operation of the tractor by the sliding operation on the operator's dominant hand side (for example, the right side) below the instruction display unit 25. And In addition, in the slide instruction area SA, a “reverse / reverse operation” that is an operation with a high operation frequency among operations that can be instructed by the instruction display unit 25 is performed.

Next, the forward / reverse operation will be described in detail.
As shown in FIG. 3, a plurality of positions are set in the slide instruction area SA in order to determine the operation itself in the forward / reverse operation.
Specifically, in the slide instruction area SA of the instruction display unit 25, a forward determination position 40 for determining a forward operation and a reverse determination position 41 for determining a reverse operation are set. "F" (forward determination unit) indicating that the vehicle is moving forward is displayed at the forward determination position 40, and "R" (reverse determination unit) indicating that the vehicle is moving backward is displayed at the backward determination position 41. Yes. The forward determination position (forward determination portion) 40 and the reverse determination position (reverse determination portion) 41 are arranged in a straight line in the vertical direction so that the forward determination position 40 and the reverse determination position 41 are connected on the straight line. A rectangular display shift bar (straight bar) 42 is shown in FIG.

An intermediate determination position 44 for determining a neutral (neutral) operation is set between the forward determination position 40 and the reverse determination position 41 and on the left side of the display shift bar 42 (opposite the dominant hand). . At the intermediate determination position 44, “N” (intermediate determination portion) indicating neutral is displayed.
Here, when the first operation tool 30A indicated in the slide instruction area SA of the instruction display unit 25 is positioned at the forward movement determination position 40, the forward movement of the tractor is designated, and when the first operation tool 30A is positioned at the reverse movement determination position 41, the tractor. When the reverse movement is designated and the first operating tool 30A is positioned at the neutral determination position, the neutral is designated. That is, in the slide instruction area SA, a forward determination position 40, a reverse determination position 41, and a neutral determination position are set at positions separated from each other, and these are operation determination positions for determining an operation.

Now, when the first operation tool 30 </ b> A is at each operation determination position, an operation corresponding to the operation determination position is determined, and the operation determination is performed by the travel instruction unit 45 of the mobile terminal 3. The travel instruction unit 45 is configured by a remote control application or the like stored in the control unit 27 or the like of the mobile terminal 3.
The operation determination by the travel instruction unit 45 will be described with reference to FIG. Note that before the forward or reverse operation is performed, the first operating tool 30A is always in the neutral determination position (the position where neither forward nor reverse is determined). For convenience of explanation, the position when the first operating tool 30A is in the neutral position before the operation is referred to as an initial position.

  As shown in FIG. 5A, for example, it is assumed that the first operating tool 30 </ b> A is at an initial position (neutral determination position) 44. From this state, the operator operates the first operating tool 30A and first slides it toward the predetermined operation via position 46 in the slide instruction area SA, and then determines the forward movement set separately from the operation via position 46. When moved to the position 40 or the reverse determination position 41, the travel instruction unit 45 determines the forward or reverse of the tractor.

  In this way, the travel instruction unit 45 does not simply determine (instruct) the operation when the first operation tool 30A is positioned at the operation determination position, but the operation is performed while the first operation tool 30A is sliding. When the operation determination position is reached via the position 46, the operation is determined. In the case of this embodiment, the operation via position 46 is set between the forward determination position 40 and the reverse determination position 41 and on the display shift bar 42.

In other words, if the first operation tool 30A slides and reaches the operation determination position from the initial position 44, the travel instruction unit 45 will not pass through the predetermined operation via position 46 unless it passes through the predetermined operation via position 46. 1 The operation determination (instruction) by the operating tool 30A is not performed.
As described above, when the operation is determined by the travel instruction unit 45, one action from the initial position 44 to the operation via position 46 and one action from the operation via position 46 to the forward determination position 40 or the reverse determination position 41 are determined. Necessary, 2 actions are required in total. As described above, by setting the moving step of the first operating tool 30A to at least two actions or more, it is possible to instruct operation without erroneous operation.

More specifically, the movement when the operator slides the first operation tool 30A is performed by the slide setting unit 47 configured by a remote control application or the like.
The slide setting unit 47 moves the first operation tool 30A in one direction, and moves the first operation tool 30A in a direction crossing the one direction set by the first slide setting unit 47A. And a second slide setting unit 47B.

Specifically, the first slide setting unit 47A fixes the slide (movement) of the first operation tool 30A from the initial position 44 to the operation passing position 46 in the horizontal direction (one direction). That is, when the first operating tool 30A at the initial position 44 is moved to the operation passing position 46, the first slide setting unit 47A can slide the first operating tool 30A only to the side.
The second slide setting unit 47B intersects the slide (movement) of the first operating tool 30A from the operation via position 46 to the advance determination position 40 with the lateral direction (one direction) set by the first slide setting unit 47A. The direction is fixed in, for example, a vertical direction (orthogonal direction) that is 90 degrees different from the horizontal direction and intersects the horizontal direction. Further, the second slide setting unit 47B sets the slide (movement) of the first operation tool 30A from the operation via position 46 to the reverse drive determination position 41 as the horizontal direction (one direction) set by the first slide setting unit 47A. For example, the crossing direction is fixed to a vertical direction (orthogonal direction) that is 90 degrees different from the horizontal direction and intersects the horizontal direction. That is, the second slide setting unit 47B allows the first operation tool 30A to be slid only vertically when moving the first operation tool 30A at the operation via position 46 to the forward movement determination position 40 or the reverse movement determination position 41. ing.

  As described above, according to the first slide setting unit 47A and the second slide setting unit 47B, when operating by moving the first operation tool 30A at the initial position 44, the first slide setting unit 47A and the second slide setting unit 47B are always moved in the horizontal direction (one direction). After sliding on the display shift bar 42, the forward movement determination position 40 and the reverse movement determination position 41 cannot be reached unless the movement direction is changed 90 degrees on the display shift bar 42 and moved in the vertical direction (orthogonal direction). (The movement locus of the first operating tool 30A is L-shaped or inverted L-shaped).

  Therefore, when the operation is performed by moving the first operation tool 30A, for example, the operator intentionally moves the first operation tool 30A horizontally while moving the first operation tool 30A sideways, and the tractor is inadvertently moved back and forth. It is possible to surely prevent the situation from proceeding. In this embodiment, the second slide setting unit 47B is configured to cause the slide (movement) of the first operation tool 30A to be in the vertical direction (the direction in which the direction is changed by 90 degrees) perpendicular to the horizontal direction set by the first slide setting unit 47A. The second slide setting unit 47B moves the slide (movement) of the first operating tool 30A in a direction crossing the direction set by the first slide setting unit 47A. There may be a direction that changes the direction by 45 degrees or a direction that changes the direction by 30 degrees.

When the first operation tool 30A is moved from the initial position 44 to the advance determination position 40 by two actions, the mobile terminal 3 sends a command (advance instruction) indicating an advance operation via the wireless communication device 21 to the control device 20. Send to.
Here, when the operation position of the shuttle lever of the tractor 2 is in the forward side [F], the control device 20 of the tractor 2 matches the operation position of the shuttle lever with the advance command transmitted from the portable terminal 3. Therefore, the tractor 2 is advanced from the stopped state in the same manner as when the operation position of the shuttle lever is set to advance.

  On the other hand, when the operation position of the shuttle lever of the tractor 2 is in the reverse side [R], the control device 20 of the tractor 2 does not match the operation position of the shuttle lever and the forward command transmitted from the portable terminal 3. Therefore, priority is given to the operation by the operating tool on the tractor side (operation by the shuttle lever), and even if a forward command is input from the mobile terminal 3, the command is not accepted and the tractor 2 is kept stopped.

  Even when the first operating tool 30 </ b> A is moved from the initial position 44 to the reverse determination position 41 by two actions, the mobile terminal 3 transmits a reverse instruction to the control device 20 via the wireless communication device 21. Similarly to the forward command, the reverse command is accepted when the operation position of the shuttle lever is coincident, and the reverse command is not accepted when the operation is not coincident with the operation position of the shuttle lever.

That is, the control device 20 of the tractor 2 performs the operation indicated by the operation position of the shuttle lever on the tractor 2 side and the operation indicated by the operation of the portable terminal 3 except for neutrality in the forward / reverse operation. Are different, the operation with the operating tool of the tractor is given priority, and the operation from the portable terminal 3 is not accepted.
When the operation on the tractor 2 side is prioritized over the operation on the portable terminal 3 side (when the operation with the operation tool of the tractor is prioritized over the instruction by the travel instruction unit 45), the instruction display unit 25 displays The tractor operation is prioritized.

  For example, when the operation position of the shift lever of the tractor 1 is on the reverse side, when the wireless communication between the control device 20 and the portable terminal 3 is established, the operation position of the shift lever on the control device 20 is on the reverse side. The backward priority signal indicating that the mobile terminal 3 is in the mobile terminal 3 is output. When the mobile terminal 3 receives the reverse priority signal, the display shift bar 42 displayed on the instruction display unit 25 displays the reverse priority on the reverse side portion (for example, the color of the display shift bar 42 including the reverse determination position 41 is changed). Light color). Similarly, when the operation position of the shift lever of the tractor 1 is on the forward side, the control device 20 outputs a forward priority signal to the portable terminal 3 when the wireless communication is established, and the portable terminal 3 displays the display shift bar 42. , The display shift bar 42 including the advance determination position 40 is lightly displayed to indicate the advance priority.

As described above, since the color of the display shift bar 42 displayed on the instruction display unit 25 of the portable terminal 3 is lighter than other portions, the operator can display the display shift bar 42 displayed on the instruction display unit 25. By looking, it can be recognized that the forward side or the reverse side has priority.
Next, a description will be given of releasing the forward or backward movement by returning the first operation tool 30A to the initial position 44, that is, the neutral position from the state where the operation determining position is set to the operation determination position. The advance or reverse is canceled by a return setting unit 48 configured by a remote control application or the like.

As shown in FIG. 5 (b), a state is shown in which the first operating tool 30 </ b> A is set to the advance determination position 40 to advance the tractor. When the operation of the tractor is determined, the first operating tool 30A remains at the forward determination position 40 that is the determined operation determination position.
Next, from this state, when the operator touches the first operation tool 30A at the forward movement determination position 40 and slides downward, that is, toward the operation via position 46, the return setting unit 48 causes the first operation tool to be moved. 30A is automatically moved toward the operation via position 46, and the direction is changed at the operation via position 46 to return to the initial position (neutral position) 44.

That is, when the first operating tool 30A is in the operation determination position (for example, the advance determination position 40), the return setting unit 48 automatically automatically slides the first operating tool 30A in one direction (downward). The first operating tool 30A can be returned from the advance determination position 40 to the initial position 44.
Therefore, when the operator simply slides the first operation tool 30A at the forward movement determination position 40 downward, the forward movement of the tractor can be quickly released and the tractor can be stopped immediately.

As described above, in the slide instruction area SA, the “forward / reverse operation” that is frequently used and easy to operate by the slide operation is performed. The tractor travel operation (for example, speed change operation or engine speed operation) is performed.
Specifically, as shown in FIG. 3, the operator's dominant hand (right hand side) and the upper side of the slide instruction area SA (upper right side of the instruction display unit 25) pushes the tractor traveling operation by a push operation. It is designated as an instruction area PA.

  As shown in FIG. 4, when the right-handed operator holds the mobile terminal 3, the push instruction area PA is easy to position the tip of the thumb of the right hand of the operator, and the indication display unit 25 is located at the tip of the thumb. Easy to push. Therefore, the push instruction area PA is a portion for performing a “shift operation” that is less frequently used than the traveling operation performed in the slide instruction area SA and is easy to perform the traveling operation by the push operation.

The speed change operation is performed by pressing a shift up button or a shift down button on the tractor side. When the operation of the shift up button or the shift down button is performed on the portable terminal 3 (on the instruction display unit 25), the same operation as the operation of pressing the shift up button or the shift down button is performed on the instruction display unit 25. The feeling of operation is best for the operator.
For this reason, in the push instruction area PA, two second operation tools 30B corresponding to the shift-up button and the shift-down button are displayed, and the second operation tool corresponding to the shift-up button (referred to as an up operation tool 301B) is displayed at the top. A second operation tool (referred to as a down operation tool 302B) displayed on the right end (above the dominant hand side) and corresponding to a downshift button is displayed below the up operation tool 301B.

In the push instruction area PA, the shift state is displayed on the left side (the side opposite to the dominant hand) of the up operation tool 301B and the down operation tool 302B.
Specifically, the left side of the up operation tool 301B is provided with a shift lever display portion 55 that displays the operation position of the shift lever on the tractor side, and [H] is displayed when the operation position of the shift lever is on the high speed side. [L] is displayed when the operation position of the shift lever is on the low speed side.

  Further, on the left side of the down operation tool 302B, there is provided a gear position display section 43 when the gear position is changed with the up operation tool 301B or the down operation tool 302B. When the up operation tool 301 </ b> B or the down operation tool 302 </ b> B is pushed, the number of shift stages is determined (designated) by the travel instruction unit 45, and the determined shift stage number is input to the control device 20 via the wireless communication device 21. The control device 20 controls the transmission device 12 according to the input gear number.

  As described above, in the instruction display unit 25, the slide instruction area SA and the push instruction area PA are set on the dominant hand side (right side) of the operator. In the slide instruction area SA, the first operation tool 30A can be slid to perform forward / reverse operation. In the push instruction area PA, the second operation tool 30B (up operation tool 301B, down operation tool 302B) is used. Shifting operation can be performed.

In the instruction display unit 25, the other side in the left-right direction, that is, the side opposite to the dominant hand side of the operator (the side opposite to the one side in the left-right direction) is an operation for setting a target engine speed (engine rotation). Several operations).
Next, the left side of the instruction display unit 25 and the engine speed operation will be described. Since the left side of the instruction display unit 25 is the opposite side to the dominant hand side (right hand side), it is referred to as an opposite side instruction area OA for convenience of explanation.

  As shown in FIG. 3, in the opposite side instruction area OA of the instruction display unit 25, a third operating tool (engine speed operating tool) 30C for instructing (setting) the target engine speed, and the actual engine speed ( A portion indicating the actual engine speed) is displayed. That is, the third operating tool 30C and the engine speed display unit 49 that displays the actual engine speed with a bar overlap each other so that the target engine speed and the actual engine speed can be identified with each other.

The engine rotation display unit 49 includes an engine rotation scale unit 50 and an engine rotation indicator unit 51.
The engine rotation scale unit 50 is configured by attaching a scale line to the area MA to which the scale is attached at a predetermined interval in the vertical direction and attaching a numerical value of the engine speed to the right side of the scale line. The engine rotation scale unit 50 can display a range from 0 to 3500 rpm.

The engine rotation index unit 51 is a digital tachometer that moves on the engine rotation scale unit 50 (rectangular area MA with a scale) according to the actual engine rotation speed acquired from the tractor side, and indicates the actual engine rotation speed. It is configured.
Specifically, the engine rotation indicator 51 includes a window 53 that is arranged along the left side of the scale in the area MA, and a bar (index bar) 54 that moves in the window 53. . When the actual engine speed is input to the portable terminal 3, the indicator bar 54 indicating the actual engine speed moves in the vertical direction in the window 53 according to the actual engine speed.

The third operation tool 30C (engine rotation operation tool) is configured by a rectangular moving body (movement indicator) having a slightly larger width (left-right width) than the window 53 of the engine rotation scale unit 50. On the side facing the scale of the movement indicator 30C, an instruction destination part 56 indicating the target engine speed is provided, and a value on the scale indicated by the instruction destination part 56 is a numerical value of the target engine speed.
The movement indicator 30 </ b> C moves in the vertical direction along the window portion 53 like the indicator bar 54. When the movement indicator 30C is moved up and down, the target engine speed indicated by the movement indicator 30C changes every 50 rpm. That is, the target engine speed change unit (change width) instructed by the movement indicator 30C is 50 rpm. For example, the target engine speed can be changed to 2500 rpm, 2550 rpm, 2600 rpm, and so on. it can.

  As described above, the movement trajectory of the indicator bar 54 (engine revolution indicator 51) indicating the actual engine speed and the movement trajectory of the movement indicator 30C (engine rotation operation tool) for setting the target engine speed are overlapped with each other. In other words, since the indicator bar 54 and the movement indicator 30C move on the same axis, the difference between the actual engine speed and the target engine speed can be directly visually recognized.

  For example, even when the target engine speed is set to 2500 rpm, a drop in which the actual engine speed decreases to 2200 rpm may occur due to the load applied to the tractor. In this case, since the position of the indicator bar 54 in the window 53 is different from the position of the movement indicator 30C, the operator can immediately grasp the drop amount of the engine speed by viewing these positional relationships. Can do.

Moreover, since the index bar 54 and the movement indicator 30C are moved in the same direction in the area MA (window portion 54), a scale for indicating the actual engine speed, and a scale for indicating the target engine speed, The information amount in the instruction display unit 25 (opposite-side instruction area OA) increases, and the instruction display unit 25 can be used effectively.
In the above-described embodiment, it has been described that the engine rotation operation tool is configured by the movement indicator 30C that can move up and down. However, in the opposite instruction area OA, in addition to the movement indicator 30C, a target can be obtained by a push operation. A fixed indicator 57 for instructing the engine speed is displayed.

  Specifically, fixed indicators 57 are displayed on the upper side and the lower side of the window portion 54. The fixing indicator 57 (upper fixing indicator 57A) on the upper side of the window portion 54 increases the target engine speed by a push operation, and the fixing indicator 57 on the lower side of the window portion 54 (lower fixing indicator 57B). ) Lowers the target engine speed by a push operation. The change unit (change width) of the target engine speed indicated by the upper fixed indicator 57A and the lower fixed indicator 57B is 10 rpm, which is smaller than the change unit (change width) of the movement indicator 30C.

That is, the target engine speed can be changed in units of 50 rpm by the movement indicator 30C, and the target engine speed can be changed in units of 10 rpm by the fixed indicator 57 (upper fixed indicator 57A, lower fixed indicator 57B).
For this reason, the rough target engine speed can be set by the movement indicator 30C by the slide operation, and the fine target engine speed can be set by the push operation by the fixed indicator 57. By combining the change widths in, the target engine speed can be easily changed.

Note that the target engine speed designated by the movement indicator 30C and the fixed indicator 57 is displayed numerically above the fixed indicator 57 in the opposite side instruction area OA. Further, the vehicle speed obtained from the tractor is displayed on the upper side where the target engine speed is displayed.
