Hereinafter, the flow of processing in each processing unit will be described. FIG. 7 is a diagram showing the system configuration of this embodiment. Each input / output device is connected to the control device 11, and the control device 11 performs various controls such as input / output of information with the operator and operation commands to the vehicle body. The control device 11 is configured to include the processing of an operation availability determination unit 701, a lever operation amount determination unit 702, a control command value determination unit 703, a vehicle body setting management unit 704, a camera image acquisition unit 705, an operation information acquisition unit 706, an operation processing unit 707, a function assignment management unit 708, an operation guide display determination unit 709, and a display control unit 710. Hereinafter, the flow of processing in each processing unit will be described.

[0031] The operation availability determination unit 701 detects the position of the shut-off lever 10 and determines the operation availability of the hydraulic excavator 1. When the shut-off lever 10 is in the locked position, the operation availability determination unit 701 determines that vehicle body operations are not available. When the shut-off lever 10 is in the unlocked position, the operation availability determination unit 701 determines that vehicle body operations are available and outputs the result. The operation availability determination unit 701 detects the position of the shut-off lever 10 and determines the operation availability of the hydraulic excavator 1. When the shut-off lever 10 is in the locked position, the operation availability determination unit 701 determines that vehicle body operations are not available. When the shut-off lever 10 is in the unlocked position, the operation availability determination unit 701 determines that vehicle body operations are available and outputs the result. The operation availability determination unit 701 detects the position of the shut-off lever 10 and determines the operation availability of the hydraulic excavator 1. When the shut-off lever 10 is in the locked position, the operation availability determination unit 701 determines that vehicle body operations are not available. When the shut-off lever 10 is in the unlocked position, the operation availability determination unit 701 determines that vehicle body operations are available and outputs the result. The operation availability determination unit 701 detects the position of the shut-off lever 10 and determines the operation availability of the hydraulic excavator 1. When the shut-off lever 10 is in the locked position, the operation availability determination unit 701 determines that vehicle body operations are not available. When the shut-off lever 10 is in the unlocked position, the operation availability determination unit 701 determines that vehicle body operations are available and outputs the result.

[0032] In the lever operation amount determination unit 702, according to signals from the operation levers 9a, 9b, 9c, and 9d, the operation amount of each operation lever is determined, and the information is output. The lever operation amount is, for example, the operation... In the lever operation amount determination unit 702, according to signals from the operation levers 9a, 9b, 9c, and 9d, the operation amount of each operation lever is determined, and the information is output. The lever operation amount is, for example, the operation... Set the neutral position of the lever to 0, represent the operation direction as positive and negative, and the operation amount as 1 to 100, -100 ~100, and determine the operation amount of each operation lever within this range.

[0033] Based on information such as the vehicle body operation permission status and the lever operation amount, the control command value determination unit 703 determines the control command value for the electronic control valve 7. The electronic control valve 7 controls the flow rate of the hydraulic oil discharged according to this control command value and drives each actuator.

[0034] In addition, the vehicle body setting management unit 704 also holds setting values related to the dynamic characteristics of the vehicle body, such as the driving mode and the working mode. The control command value determination unit 703 described above determines the control command value in consideration of these vehicle body setting information.

[0035] The camera image acquisition unit 705 acquires video signals from the cameras 8a, 8b, 8 c attached to the upper swing body 1d, performs image correction and synthesis processing as necessary, and outputs the result to the display control unit 71 0.

[0036] The operation information acquisition unit 706 acquires signals from the input device 13 (jog dial 13a and push buttons 13b, 13c, 13d, 13e) and converts them into operation information of each switch. The operation information includes, for example, the rotation direction and rotation amount of the jog dial 13a, and the pressed states of the push buttons 13b, 13c, 13d, 13e.

[0037] The operation processing unit 707 performs various processes using the operation information. FIG. 8 is a diagram showing the flow of the processes of the operation processing unit 707. In the operation processing unit 707, first, in step 707 a, the jog dial 13a and the push buttons 13b, 13c, 13d, 13 ​​​​​Obtain the operation information of e. Next, proceed to the process of step 707b and make a determination based on whether there is an operation. If there is no operation on any switch, return to step 707a and obtain the operation information again.

[0038] In step 707b, if there is an operation on the switch, proceed to step 707c and obtain the information of the display screen currently displayed on the touch monitor 12 from the display control unit 710.

[0039] Next, in step 707d, perform branch processing according to the type of this current display screen.

[0040] First, when the current display screen is the basic screen 600A including the operation guide, proceed to step 707e and obtain the current mode of the input device 13 and the function assignment information of each switch from the function assignment management unit 708. Note that the function assignment management unit 708 holds the function assignment information of the switches in each mode of the input device 13 and manages the currently selected mode. Next, in step 707f, perform a branch according to the content of the operation. In step 707f if the operation content is the rotation operation of the jog dial 13a or the pressing operation of the push buttons 13b, 1 3c, 13d, 13e, in step 707g, determine the operation content according to the current function assignment and issue a request to change the vehicle body settings to the vehicle body setting management unit 704.

[0041] In step 707f, if the operation content is the pressing operation of the jog dial 13a, proceed to step 7 07h and output a request to transition to the menu screen 600C to the display control unit 710. Note that for the process of transitioning to the menu screen 600C, the work mode 401 ​​​​​, since it is a function common to the air conditioner mode 402 and the audio mode 403, the process is executed without depending on the current function assignment. The process is executed without depending on the current function assignment.

[0042] Also, in step 707f, when the operation content is a slide operation of the jog dial 13a, it proceeds to step 707i, and according to the current mode and the slide operation direction, the changed mode is determined, and the mode change request (function assignment change request) is output to the function assignment management unit 708. Note that the correspondence between the slide operation direction and each mode is as shown in FIG. 4.

[0043] In step 707d, when the current display screen is the basic screen 600B that does not include the operation guide 609, it proceeds to step 707j. When the operation guide 609 is not displayed on the basic screen, it is highly likely that the operator does not recognize the functions of each switch. Therefore, in step 707j, the process corresponding to each switch operation (the process corresponding to the current function assignment of each switch) is not executed, and the process of the operation processing unit 707 ends. At this time, in the operation guide display determination unit 709 described later, an instruction is output to the display control unit 710 to display the operation guide 609 on the basic screen, and the display screen is switched to the basic screen 600A including the operation guide 609. After the display screen is switched from the basic screen 600B that does not include the operation guide 609 to the basic screen 600A including the operation guide 609, by operating the input device 13 again, it proceeds from step 707d to step 707e, and it becomes possible to execute the process according to the current function assignment of the input device 13. After switching from the basic screen 600B that does not include the operation guide 609 to the basic screen 600A that includes the operation guide 609, by operating the input device 13 again, it proceeds from step 707d to step 707e, and it becomes possible to execute the process according to the current function assignment of the input device 13. The process can be executed according to the current function assignment of the input device 13.

[0044] Note that, like the process of transitioning to the menu screen 600C in step 707h, for each mode For common functions, the operator is unlikely to misunderstand the function assignment, so the operation guide is The basic screen 600B not including the button 609 may also be designed to allow processing to be executed.

[0045] Finally, in step 707d, if the current display screen is the menu screen 600C, In this case, the operator can use the input device 13 for screen operation without the operation guide 609. Since it is easy to guess that the process is performed in the order of steps 707k and 707l, Executes screen operation processing according to the operation of the input device 13, such as moving forward, moving the focus, or deciding. In other words, the input device 13 is used to operate the display screen displayed on the touch monitor 12. When the screen operation function is assigned, the display screen of the touch monitor 12 changes to Operation Guide 6. Regardless of whether it is a basic screen 600A including 09 or a basic screen 600B not including the operation guide 609 First, in response to the operation of the input device 13, the screen operation is processed according to the current function allocation of the input device 13. Carry out the theory.

[0046] The processes for the operation of each switch described here are merely examples. The mode of the input device 13 is changed by sliding the dial 13a up and down. For example, the function for each operation can be freely assigned, for example, the function for the menu screen 600C can be changed by pressing the button 13b. You may set this.

[0047] Next, the process of the manipulation guidance display determination unit 709 will be described. 13 is a diagram showing a process flow in the production guide display determination unit 709. FIG.

[0048] First, in step 709 a , current display screen information is obtained from the display control unit 710 . Next, in step 709b, branch processing according to the current display screen is performed.

[0049] In step 709b, when the current display screen is the basic screen 600B that does not include the operation guide 609, the process proceeds to step 709c, and operation information of the input device 13 is acquired from the operation information acquisition unit 706. After that, in step 709d, branch processing according to the presence or absence of an operation is performed. First, in step 709d, when the input device 13 has not been operated, the process proceeds to step 709e, and the display control unit 710 is continuously instructed to hide the operation guide 609.

[0050] On the other hand, in step 709d, when the input device 13 has been operated, the process proceeds to step 709f, and the display control unit 710 is instructed to display the operation guide 609. In this way, when the operation guide 609 is not displayed, the process is performed so that the operation guide 609 is displayed in response to any operation of the input device 13 (in other words, when any operation of the input device 13 occurs, the display screen of the touch monitor 12 is switched from the basic screen 600B that does not include the operation guide 609 to the basic screen 600A that includes the operation guide 609), so that when the operator attempts an operation of the input device 13, the function assignment of each switch can be confirmed without requiring any other special operations. Also, when the operation guide 609 is not displayed, in the operation processing unit 707, in step 707j, the process by the operation of the input device 13 (the process according to the current function assignment of the input device 13) is not executed, so it is possible to prevent the operator from making a wrong vehicle body setting while misrecognizing the function assigned to the input device 13.

[0051] In addition, for functions common to each mode, such as the operation to transition to the menu screen 600C, since it is less likely that the operator will misidentify the function assignment, even if there is an operation of the input device 13 in step 709d, it may be set to keep the operation guide 609 hidden.

[0052] In step 709f, after instructing the display control unit 710 to display the operation guide 609, proceed to step 709g and perform a process of resetting the timer of the timer management unit 709h. The timer management unit 709h counts the time during which the operation guide 609 is displayed and the input device 13 remains in an inoperative state. Therefore, at the timing when the operation guide 609 switches from non-display to display, or at the timing when an operation of the input device 13 is input, a process of resetting the timer is executed.

[0053] In step 709b, if the current display screen is the menu screen 600C, as described above, since the operator can easily infer that the input device 13 can be used for screen operations even without the operation guide 609, proceed to step 709e and instruct to hide the operation guide 609.

[0054] In step 709b, if the current display screen is the basic screen 600A including the operation guide 609, proceed to step 709i of FIG. 10. In step 709i, operation information of the input device 13 is acquired from the operation information acquisition unit 706, and further, in step 709j, branch processing according to the presence or absence of an operation is performed. In step 709j, an operation of the input device 13 ​​​​​​​​​​If so, proceed to steps 709f and 709g in FIG. 9, and continue to display the operation guide 609 and perform a process of resetting the timer of the timer management unit 709h.

[0055] In step 709j, if there is no operation on the input device 13, proceed to step 709k to obtain the touch operation information of the touch monitor 12. Then, in step 709l determine whether a non-display operation of the operation guide 609, that is, a tap operation on the operation guide non-display button 612 of the basic screen 600A, has been performed. If a tap operation on the operation guide non-display button 612 of the basic screen 600A has been performed, since the operator determines that the operation guide 609 is unnecessary, proceed to step 709m and output an instruction to make the operation guide 609 non-displayed.

[0056] In step 709l, if the non-display operation of the operation guide 609 has not been performed, in step 709n, determine whether the timer of the timer management unit 709h has reached a predetermined time or more. In step 709n, if the predetermined time has elapsed, proceed to step 709m and output an instruction to make the operation guide 609 non-displayed. When the operation guide 609 is displayed and the operation of the input device 13 has not been performed for a predetermined time or more (when the state where the input device 13 has not been operated has elapsed for a certain time), the operator can determine that there is no intention to operate the input device 13. In such a case, perform a process of automatically making the operation guide 609 non-displayed (switch the display screen of the touch monitor 12 from the basic screen 600A including the operation guide 609 to the basic screen 600B not including the operation guide 609), ​​​​​​​​​​​​The palletizer no longer needs to operate the operation guide non-display button 612 on the basic screen 600A, so it is possible to work efficiently.

[0057] In step 709n, when the timer of the timer management unit 709h has not reached a predetermined time or more, the process proceeds to step 709o, the operability state of the vehicle body is acquired, and the vehicle body operability state is stored in the storage unit 709p. The vehicle body operability state storage unit 709p holds the current operability state and the operability state at the time of the previous processing cycle. In step 709q, by comparing these states, it is determined whether the vehicle body has transitioned from an inoperable state to an operable state. In step 709q, when the vehicle body has transitioned from an inoperable state to an operable state, in step 709m, an instruction is issued to make the operation guide 609 non-displayed. At this time, since it can be determined that the operator has moved the shut-off lever 10 to the unlocked position and intends to start the operation of the hydraulic excavator 1, a process of automatically making the operation guide 609 non-displayed is performed (the display screen of the touch monitor 12 is switched from the basic screen 600A including the operation guide 609 to the basic screen 600B not including the operation guide 609), so that the palletizer no longer needs to operate the operation guide non-display button 612 on the basic screen 600A, and thus it is possible to work more efficiently. In step 709q, when there is no change in the operability state of the vehicle body, the process proceeds to step 709 r to acquire the operation state of the operation lever. In step 709r, step 709t, and the lever operation state storage unit 709s, similar to the above processing, when the operation lever transitions from a non-operated state to an operated state, the palletizer no longer needs to operate the operation guide non-display button 612 on the basic screen 600A,

[0058] so that it is possible to work more efficiently. r to acquire the operation state of the operation lever. In step 709r, step 709t, and the lever operation state storage unit 709s, similar to the above processing, when the operation lever transitions from a non-operated state to an operated state, Determine whether or not a transition has occurred to the operating state, and when the operation lever transitions from the non-operating state to the operating state in step 709m, an instruction to make the operation guide 609 non-displayed is output. On the other hand, in step 709t, if there is no change in the lever operation state, the process proceeds to step 709u and an instruction to continue displaying the operation guide 609 is output.

[0059] In the present embodiment, based on the operability state of the vehicle body and the lever operation state, the process of making the operation guide 609 non-displayed is described. Conversely, when the vehicle body transitions to the inoperable state or when a certain period of time has elapsed after the operation lever transitions to the non-operating state, that is, when it is highly likely that the operator will operate the input device 13, the operation guide 609 may be displayed. By adding such a process, the operator does not need to operate the input device 13 once to display the operation guide 609, so that it becomes possible to perform the setting operation by the input device 13 more efficiently. Once, the trouble of displaying the operation guide 609 is eliminated, so that it becomes possible to perform the setting operation by the input device 13 more efficiently.

[0060] The display control unit 710 generates a display screen based on various vehicle body settings, function assignments of the input device 13, and information such as display instructions for the operation guide 609, and outputs it to the touch monitor 12. .

[0061] In this way, in the present embodiment, based on the operation state of the input device 13 and various vehicle body states, it is determined whether or not the operator needs the operation guide 609, and the operation guide 609 is displayed on the touch monitor 12 as needed.

[0062] Also, when the operation guide 609 is not displayed on the touch monitor 12, the input device 13 ​Since the process by the operation is not performed, the operator may operate while misidentifying the assigned function without causing, and without degrading the visibility of other display information during work, the input to the operator of the function assignment information of the input device 13 becomes possible.

[0063] [Summary] As described above, the working machine (hydraulic excavator 1) of the present embodiment is (related to work ) an input device 13 (jog dial 13a and push buttons 13 b, 13c, 13d, 13e) capable of selectively assigning a plurality of predetermined functions (including a function of adjusting the rotational speed of a prime mover (engine, motor, etc.) that drives the working machine) and selectively assigning any one of a plurality of predetermined functions, a display device ( touch monitor 12) that switches and displays a first display screen including the setting information ( operation guide 609) of the function assigned to the input device 13 and a second display screen not including the setting information (operation guide 609) of the function assigned to the input device 13, a control device 11 that acquires the operation information of the input device 13 (operation information acquisition unit 706), manages the function assignment of the input device 13 (function assignment management unit 708), and when the input device 1 3 receives an operation, executes a process corresponding to the function assigned to the input device 13 (operation processing unit 707) and controls the display screen displayed on the display device (display control unit 710). In a working machine including the above, when the first display screen is being displayed on the display device (touch monitor 12), when the input device 13 receives an operation, the control device 11 executes a process corresponding to the function assigned to the input device 13, and when the second display screen is being displayed on the display device (touch monitor 12), the control device 11 executes a process corresponding to the function assigned to the input device 13, When in a certain state, if the input device 13 receives an operation, without executing the process corresponding to the function assigned to the input device 13, the display screen of the display device (touch monitor 12) is controlled to switch from the second display screen to the first display screen.

[0064] Also, the work machine (hydraulic excavator 1) has a switching unit that selectively (by operator operation) switches the display screen of the display device between the first display screen and the second display screen. .

[0065] Further, when a state where the input device 13 is not being operated has elapsed for a certain period of time, the control device 11 controls the display screen of the display device to switch from the first display screen to the second display screen.

[0066] Also, the control device 11 determines the operable state of the work machine (operation permission determination unit 7 01), and when the work machine transitions from an inoperable state to an operable state, controls the display screen of the display device to switch from the first display screen to the second display screen.

[0067] Also, the control device 11 determines the operation state of the work machine (lever operation amount determination unit 7 02), and when the work machine transitions from a non-operated state to an operated state, controls the display screen of the display device to switch from the first display screen to the second display screen.

[0068] Also, the work machine (hydraulic excavator 1) is provided with cameras 8a, 8b, 8c for photographing the surroundings of the work machine, and on the first display screen and the second display screen, the cameras ​The camera images captured by cameras 8a, 8b, and 8c are displayed and are displayed on the second display screen. The display area of the camera image displayed on the second display screen is larger than the display area of the camera image displayed on the first display screen.

[0069] Also, the input device 13 is composed of a plurality of operation parts (jog dial 13a and push buttons 13b, 13c, 13d, 13e) to which the predetermined functions can be respectively assigned. When the control device 11 is in a state where the second display screen is displayed on the display device and any specific operation part among the plurality of operation parts receives an operation, the display screen of the display device is switched from the second display screen to the first display screen. The first display screen includes the setting information of the function assigned to the specific operation part and the setting information of the functions assigned to the operation parts different from the specific operation part among the plurality of operation parts.

[0070] Also, when the control device 11 has assigned a screen operation function for operating the display screen displayed on the display device to the input device 13 and the input device 13 receives an operation, regardless of whether the display screen of the display device is the first display screen or the second display screen, for the operation of the input device 13, screen operation processing corresponding to the current function assignment of the input device 13 is executed.

[0071] Also, the input device 13 receives an operation for switching the function assigned to the input device 13 and an operation for executing processing corresponding to the function assigned to the input device 13.

[0072] Also, the plurality of predetermined functions are prime movers (engines, motors, etc.) that drive the work machine.​​​​​​​​​​ ) a function for adjusting the rotational speed, a function for adjusting the volume of the audio in the cab of the work machine, and a function for adjusting the air volume of the air conditioner in the cab of the work machine.

[0073] The input device 13 according to this embodiment includes a first display screen including the current function assignment information (operation guide 6 09) of the input device 13 and a second display screen not including the current function assignment information (operation guide 609) of the input device 13. While the second display screen is being displayed, regardless of the current function assignment, a process for causing a transition to the first display screen in response to an operation of the input device 13 is executed. By executing such a process, the operator can perform various setting operations after checking the first display screen including the current function assignment information, so that it is possible to operate without misidentifying the currently assigned function. Also, until the operator operates the input device 13, since the second display screen not including the function assignment information is displayed, it is possible to perform work without impairing the visibility of other display information.

[0074] Further, by providing means (switching unit) for selectively transitioning from the first display screen to the second display screen, the operator can display the second display screen at an arbitrary timing when the current function assignment information is no longer required, improving the visibility of the display information with high priority during work, and enabling efficient work.

[0075] Also, when a state where the input device 13 is not being operated has elapsed for a certain period of time, by controlling to display the second display screen, when it is determined that the operator has finished operating the input device 13 and the current function assignment information is no longer required, the second display screen is automatically displayed. Thus, the operator can save the trouble of switching to the second display screen, and it is possible to improve the work efficiency.

[0076] In addition, by determining the operating state of the work machine and controlling to display the second display screen when the work machine transitions from a non-operating state to an operating state, when the operator starts operating the work machine, that is, when transitioning to a situation where there is a low possibility of operating the input device 13, the second display screen is automatically displayed, and by improving the visibility of display information other than the current function allocation information, it is possible to perform work efficiently.

[0077] In addition, by determining the operability state of the work machine and controlling to display the second display screen when the work machine transitions from a non-operable state to an operable state, when the operator is about to start operating the work machine, that is, when transitioning to a situation where there is a low possibility of operating the input device 13, the second display screen is automatically displayed, and by improving the visibility of display information other than the current function allocation information, it is possible to perform work efficiently.

[0078] In addition, by making the display area of the camera image displayed on the second display screen larger than the display area of the camera image displayed on the first display screen, in the second display screen that does not include the current function allocation information, it becomes easier to visually recognize the situation around the work machine, so it is possible to perform work efficiently.

[0079] In addition, when the input device 13 is composed of a plurality of operation parts (jog dial 13a and push buttons 13 b, 13c, 13d, 13e), when any one of the operation parts is ​​​​​​​​​​When there is an operation, control is performed to display a first display screen including function assignment information of an operation unit different from the operated operation unit, so that it is not necessary to switch the function assignment information for each operation of each operation unit. Therefore, when continuously operating a plurality of operation units, the number of operations of the input device 13 can be reduced, and the input device can be operated efficiently. Also, when a screen operation function for operating the display screen displayed on the display device (touch monitor 12) is assigned to the input device 13, even if the function assignment information is not directly displayed, the operator can infer from the display content of the display screen that the current function assignment is the screen operation function. Therefore, when the screen operation function is assigned to the input device 13, it is possible to efficiently perform the screen operation by enabling the screen operation process regardless of the display or non-display of the function assignment information. As described above, according to the present embodiment, information indicating the current function assignment can be presented to the operator without misidentifying the assigned function and without reducing the visibility of other display information during work. In the present embodiment, the operation of the present invention has been described by taking a hydraulic excavator as an example, but the present invention is not limited to the above-described embodiment, and various modifications are possible. For example, the present invention is not limited to having all the configurations described in the above embodiment, and also includes those in which a part of the configuration is deleted.

[0080] Also, each configuration related to the control device 11, the functions and execution processes of the respective configurations, etc. When there is an operation, control is performed to display a first display screen including function assignment information of an operation unit different from the operated operation unit, so that it is not necessary to switch the function assignment information for each operation of each operation unit. Therefore, when continuously operating a plurality of operation units, the number of operations of the input device 13 can be reduced, and the input device can be operated efficiently. Also, when a screen operation function for operating the display screen displayed on the display device (touch monitor 12) is assigned to the input device 13, even if the function assignment information is not directly displayed, the operator can infer from the display content of the display screen that the current function assignment is the screen operation function. Therefore, when the screen operation function is assigned to the input device 13, it is possible to efficiently perform the screen operation by enabling the screen operation process regardless of the display or non-display of the function assignment information. As described above, according to the present embodiment, information indicating the current function assignment can be presented to the operator without misidentifying the assigned function and without reducing the visibility of other display information during work.
