[0024] Figure 6 shows an example of a screen displayed on the touch monitor 12. In this embodiment, The display screen of the touch monitor 12 is the basic screen (with operation guide) 600A, and the basic screen (with operation guide) It can be classified into three screens: 600B (no ID), 600C (menu screen), and each These correspond, in order, to the first display screen, the second display screen, and the second display screen of the present invention.

[0025] The basic screen refers to the screen displayed during operation of the hydraulic excavator 1, and the frequency with which it is checked during operation. High-quality fuel gauge 606, water temperature gauge 607, and overhead view 608 created by combining images from a camera, etc. The following is displayed. Also, the basic screen shows the operation guide 6 which indicates the function assignment of the input device 13. Basic screen 600A with 09 displayed, and basic screen without operation guide 609 displayed. Surface 600B exists.

[0026] In the example in Figure 6, the basic screen 600B, where the operation guide 609 is not displayed, shows an overhead view. In addition to 608, the rear camera image 613 is displayed, and the image displayed on the main screen 600B The display area of ​​the camera image is larger than the display area of ​​the camera image displayed on the basic screen 600A. This makes it easier to check the surrounding situation. As shown, the operation guide 609 is displayed. If not present, that area can be utilized to improve the visibility of existing display information or to add additional display information. That is the case.

[0027] From the basic screen 600A where the operation guide 609 is displayed, the operation guide 609 is displayed As an example of a means to transition to the unviewed base screen 600B, the operation of base screen 600A There is a tap operation for the hide operation guide button 612. In addition, there is a swipe operation guide 609. The operator can perform operations and settings within the 600C menu screen at any time. A means may be provided to hide the operation guide 609 (by transitioning to the basic screen 600B). Furthermore, as in this embodiment, the display of the operation guide 609 is linked to the presence or absence of the display (operation guide 60 (To the left of 9) Air conditioner status display 610, (To the right of operation guide 609) Audio status display You may toggle the display of information that is not frequently checked while driving, such as display 611.

[0028] On the other hand, the 600C menu screen allows you to check and change various settings of the vehicle through screen operation. This can be done. Figure 6 shows the top menu screen immediately after transitioning to menu screen 600C. An example of a screen is shown. When operating the screen on this screen, multiple icons 614-621 are displayed. Move the focus 622 to the designated icon and confirm by pressing the dial. You can transition to the next level of the screen. In this way, within the menu screen 600C, Perform operations such as jog dial 13a or push buttons 13b and 13c on the display surface. Next, check and change various settings.

[0029] In addition to screen operation via input device 13, the menu screen 600C can also be operated by touch. The system may also be designed to allow screen operation. In this embodiment, within the menu screen 600C The operation guide 609 is completely hidden, but for example, push buttons 13b, 13c Only certain operation guides are partially available, such as the operation to return to the previous screen / return to the main screen. It may also be specified to display it in [this location].

[0030] Figure 7 shows the system configuration of this embodiment. Each input / output device is connected to the control device 11. The control device 11 is connected and performs various functions such as inputting and outputting information with the operator and issuing operation commands to the vehicle body. Control is performed. The control device 11 includes an operation feasibility determination unit 701, a lever operation amount determination unit 702, and control Command value determination unit 703, vehicle body setting management unit 704, camera image acquisition unit 705, operation information acquisition unit 706, Operation Processing Unit 707, Function Assignment Management Unit 708, Operation Guide Display Determination Unit 709, Display The system is configured to include processing by the control unit 710. The following describes the processing flow in each processing unit. I will explain.

[0031] The operation feasibility determination unit 701 detects the position of the shut-off lever 10 and determines the operation feasibility of the hydraulic excavator 1. The operation feasibility determination unit 701 determines whether the device is operational or not. At some point, if the vehicle's operation is deemed impossible and the shut-off lever 10 is in the unlocked position, The system then determines that the vehicle's operation is possible and outputs the result.

[0032] The lever operation amount determination unit 702 determines the signal from the operating levers 9a, 9b, 9c, and 9d in accordance with the signal. Then, the amount of operation of each control lever is determined and that information is output. The amount of lever operation is, for example, The neutral position of the lever is set to 0, the operating direction is expressed as positive or negative, and the operating amount is expressed as 1 to 100, with -100 being... The amount of movement for each control lever is determined within a range of ~100.

[0033] The control command value determination unit 703 electronically controls the vehicle based on information such as the vehicle body operation status and lever operation amount. The control command value for valve 7 is determined. The electronic control valve 7 operates according to this control command value. The flow rate of the hydraulic fluid discharged is controlled to drive each actuator.

[0034] Furthermore, the vehicle body setting management unit 704 handles the dynamic characteristics of the vehicle body, such as driving mode and work mode. The control command value determination unit 703 also retains the set values, and takes these vehicle setting information into account. Determine the control command value beforehand.

[0035] The camera image acquisition unit 705 uses cameras 8a, 8b, and 8 attached to the upper rotating body 1d. The video signal from c is acquired, and if necessary, the video is corrected or combined, and the display control unit 71 Output to 0.

[0036] The operation information acquisition unit 706 uses the input device 13 (jog dial 13a and push button The signals from switches 13b, 13c, 13d, and 13e are acquired and converted into operation information for each switch. The operating information includes, for example, the rotation direction and amount of rotation of the jog dial 13a, and each push button. This includes the pressing status of buttons 13b, 13c, 13d, and 13e.

[0037] The operation processing unit 707 uses the operation information to perform various processes. Figure 8 shows the operation process. This diagram shows the processing flow of section 707. In the operation processing unit 707, first, step 707 In a, the jog dial 13a and push buttons 13b, 13c, 13d, 13 Obtain the operation information for e. Next, proceed to step 707b to make a determination based on whether or not an operation was performed. Perform the following. If no switch is operated, return to step 707a and check the operation information again. Obtain the information.

[0038] If a switch is operated in step 707b, proceed to step 707c. The display control unit 710 acquires information about the display screen currently shown on the touch monitor 12. ru.

[0039] Next, in step 707d, branching processing is performed according to the type of the current display screen.

[0040] First, if the current display screen is the basic screen 600A which includes the operation guide, then step 707e Next, the function assignment management unit 708 displays the current mode of the input device 13 and the function assignment of each switch. This information is obtained. The function assignment management unit 708 then determines the input device 13 in each mode. It maintains the assignment information for the switch's functions and manages the currently selected mode. Next, in step 707f, branching is performed according to the content of the operation. Step 707f In this case, the operation is either the rotation of the jog dial 13a or the push buttons 13b, 1 When pressing 3c, 13d, or 13e, in step 707g, the current function assignment The system determines the operation content corresponding to the operation and issues a request to change the vehicle settings to the vehicle settings management unit 704. To exert force.

[0041] In step 707f, if the operation is pressing the jog dial 13a, The process proceeds to step 707h, and a request is sent to the display control unit 710 to transition to the menu screen 600C. Output. Note that the process of transitioning to menu screen 600C is performed in work mode 401. Since this is a function common to both air conditioning mode 402 and audio mode 403, the current model The process is executed independently of the allocation.

[0042] Furthermore, in step 707f, the operation is a sliding operation of the jog dial 13a. If so, proceed to step 707i, and change the mode according to the current mode and slide operation direction. The system determines the mode and outputs a mode change request (function assignment change request) to the function assignment management unit 708. The correspondence between the slide operation direction and each mode is shown in Figure 4.

[0043] In step 707d, the current display screen is the basic screen 6 which does not include the operation guide 609. If it is 00B, proceed to step 707j. Operation guide 609 will be displayed on the main screen. If they are not present, it is highly likely that the operator is unaware of the function of each switch. In step 707j, processing is performed according to each switch operation (the current function assignment of each switch). The operation processing unit 707 completes its processing without executing the corresponding operation. The guide display determination unit 709 determines whether to display the operation guide 609 on the basic screen. Instructions for 710 are output, and the display screen changes to the basic screen 600A, which includes the operation guide 609. The switching process is executed. The display screen is the basic screen 600B, which does not include the operation guide 609. After switching to the basic screen 600A, which includes the operation guide 609, the input device 13 is again... By performing the operation, the process proceeds from step 707d to step 707e, and the input device 13 It will be possible to execute processes according to the current function assignments.

[0044] Furthermore, as in the process of transitioning to menu screen 600C in step 707h, each mode For standard functions, the likelihood of operators misinterpreting function assignments is low, so the operation guide The system may also be designed to allow processing to be executed on the basic screen 600B, which does not include D609.

[0045] Finally, in step 707d, if the current display screen is menu screen 600C In addition, the operator can use the input device 13 for screen operation even without the operation guide 609. Since it is easy to infer that this is the case, the processing is carried out in the order of steps 707k and 707l. The system executes screen operation processing according to the operation content of the input device 13, such as moving forward, shifting focus, and making a selection. In other words, the input device 13 performs operations on the display screen shown on the touch monitor 12. If a screen operation function is assigned, the display screen of the touch monitor 12 will show the operation guide 6. Whether it is the basic screen 600A which includes 09 or the basic screen 600B which does not include the operation guide 609 In response to the operation of the input device 13, the screen operation corresponding to the current function assignment of the input device 13 is processed. To put reason into practice.

[0046] Note that the processing for each switch operation described here is just an example; for example, jog dial The mode of the input device 13 is changed by sliding YAR 13a up and down, push button You can freely assign functions to each operation, such as transitioning to menu screen 600C with n13b. You can set it.

[0047] Next, the processing of the operation guide display determination unit 709 will be described. Figures 9 and 10 show the operation This diagram shows the processing flow in the production guide display determination unit 709.

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

[0049] In step 709b, the current display screen is the basic screen 6 which does not include the operation guide 609. If it is 00B, proceed to step 709c, and the operation information acquisition unit 706 receives the input device 13 Operation information is obtained. Then, in step 709d, branch processing is performed depending on whether an operation was performed or not. First, in step 709d, if the input device 13 has not been operated, Proceed to step 709e and continue to instruct the display control unit 710 to hide the operation guide 609. conduct.

[0050] On the other hand, if the input device 13 is operated in step 709d, then step 709 The process proceeds to step f, and the display control unit 710 is instructed to display the operation guide 609. If Guide 609 is not displayed, the operation will be guided by any operation of the input device 13. Perform the process so that ID 609 is displayed (in other words, any operation of input device 13) If this occurs, the display screen of the touch monitor 12 will be the basic screen 60 which does not include the operation guide 609. By switching from 0B to the basic screen 600A, which includes the operation guide 609, the operator When Ta attempted to operate the input device 13, each switch was activated without requiring any other special operation. You will be able to check the function assignments. Also, the display in operation guide 609 will be If not, the operation processing unit 707, in step 707j, controls the input device 13. Because the processing by the operator (processing according to the current function assignment of input device 13) is not performed, The operator misinterpreted the function assigned to the input device 13 and incorrectly set the vehicle body. It is possible to prevent this from happening.

[0051] Regarding functions common to all modes, such as the operation to transition to menu screen 600C, Therefore, because the operator is less likely to misinterpret the function assignment, in step 709d Even if the force device 13 is operated, the operation guide 609 will remain hidden. That's good too.

[0052] In step 709f, after instructing the display control unit 710 to display the operation guide 609, Proceed to step 709g, where the timer management unit 709h is reset. The current management unit 709h displays the operation guide 609 and the input device 13 is in an idle state. The duration of the action is counted. Therefore, the operation guide 609 is switched from hidden to visible. At the moment of the change, or at the moment of input device 13 operation, the timer Perform a reset process.

[0053] In step 709b, if the current display screen is menu screen 600C, As mentioned above, even without the operation guide 609, the operator can use the input device 13 to operate the screen. Since it is easy to infer that it can be used, proceed to step 709e and operate the Instruct ID609 to be hidden.

[0054] In step 709b, the current display screen is the basic screen 600, which includes the operation guide 609. If the result is A, proceed to step 709i in Figure 10. In step 709i, operation information The acquisition unit 706 acquires the operation information of the input device 13, and further, in step 709j The system performs branching processing depending on whether or not an operation is performed. In step 709j, the operation of the input device 13 If this occurs, proceed to steps 709f and 709g in Figure 9, and continue with the operation guide 609. The system displays an instruction and performs a process to reset the timer in the timer management unit 709h.

[0055] If no operation was performed on the input device 13 in step 709j, then in step 709k... The process proceeds to acquire touch operation information from the touch monitor 12. Then, in step 709l, Therefore, the operation to hide the operation guide 609, that is, the operation guide hide button on the basic screen 600A Determines whether a tap operation was performed on n612. Operation guide for basic screen 600A is not If the display button 612 is tapped, the operator does not need the operation guide 609. To indicate that you have made a decision, proceed to step 709m and hide the operation guide 609. Output the display.

[0056] If the operation to hide the operation guide 609 has not been performed in step 709l, In step 709n, the timer of the timer management unit 709h has exceeded a predetermined time. Determine whether or not. In step 709n, if a predetermined time has elapsed, Proceed to step 709m and output an instruction to hide operation guide 609. Operation guide If 609 is displayed and the input device 13 has not been operated for a predetermined time or longer (input If the device 13 has not been operated for a certain period of time, the operator will input device 13 It can be determined that there is no intention to operate it. In such cases, the operation guide 609 is automatically hidden. Perform the process to display (the display screen of the touch monitor 12, including the operation guide 609, is the basic screen 6 By switching from 00A to the basic screen 600B (which does not include the operation guide 609), The operator no longer needs to operate the hide button 612 on the basic screen 600A. Therefore, it is possible to work efficiently.

[0057] In step 709n, the timer of the timer management unit 709h exceeds a predetermined time. If not present, proceed to step 709o to obtain the vehicle's operational status. The information is stored in the memory unit 709p. The vehicle operation status memory unit 709p stores the current operation status and The operational status at the time of the previous processing cycle is retained, and in step 709q, By comparing the respective states, it was determined that the vehicle body transitioned from an inoperable state to an operable state. A determination is made as to whether or not the vehicle is operational. In step 709q, the vehicle body changes from an inoperable state to an operational state. If the state is transitioned, step 709m will issue an instruction to hide the operation guide 609. At this time, the operator moves the shut-off lever 10 to the unlocked position, and the hydraulic system Since it can be determined that the user intends to start operating Shovel 1, the operation guide 609 is automatically disabled. Perform the process to display (the display screen of the touch monitor 12, including the operation guide 609, is the basic screen). By switching from 600A to the basic screen 600B (which does not include the operation guide 609), The operator does not need to operate the operation guide hide button 612 on the basic screen 600A. Therefore, it becomes possible to work more efficiently.

[0058] In step 709q, if there is no change in the operational status of the vehicle body, then step 709 Proceed to r and obtain the operating status of the control lever. Step 709r, Step 709t, r In the bar operation state storage unit 709s, similar to the above process, when the operation lever changes from an unoperated state to an operational state Determine whether the operation has transitioned to the operation state, and if the operation lever has transitioned from the non-operation state to the operation state. In step 709m, an instruction is output to hide the operation guide 609. Meanwhile, If there is no change in the lever operation state at step 709t, proceed to step 709u. The system outputs an instruction to continue displaying the operation guide 609.

[0059] In this embodiment, the operation guide 609 is disabled based on the operational status of the vehicle body and the lever operation status. The process for displaying this information is described, but conversely, if the vehicle body transitions to an inoperable state, If a certain amount of time has elapsed since the operating lever transitioned to the non-operated state, that is, if the operator When a situation arises where it is highly likely that the input device 13 will need to be operated, the operation guide 609 will be displayed. This may be a process that involves adding such processing. By adding this processing, the operator can use the input device 13. This eliminates the need to operate the device once and display the operation guide 609, making the input device more efficient. It becomes possible to perform setting operations using step 13.

[0060] The display control unit 710 handles various vehicle body settings, function assignments for the input device 13, and operation guidance. Based on the information such as the display instructions of D609, a display screen is generated and output to the touch monitor 12. .

[0061] Thus, in this embodiment, the operator is determined based on the operating state of the input device 13 and various vehicle body conditions. Determine whether the user is in a situation where they require the operation guide 609, and if necessary, operate The production guide 609 is displayed on the touch monitor 12.

[0062] Also, if the operation guide 609 is not displayed on the touch monitor 12, the input device 13 Because the operation does not perform the processing, it may result in the user misunderstanding the assigned function. Without reducing the visibility of other displayed information during operation, the operator can input data. It becomes possible to display the function assignment information for device 13.

[0063] [summary] As explained above, the work machine (hydraulic excavator 1) of this embodiment is (related to work) ) A prime mover (engine) that drives a work machine to which multiple predetermined functions can be selectively assigned. Select one of several predetermined functions, including a function to adjust the rotation speed of a motor, etc. Input device 13 (jog dial 13a and push button 13) which can be selectively assigned b, 13c, 13d, 13e) and setting information of the function assigned to the input device 13 ( The first display screen, including the operation guide 609), and the functions assigned to the input device 13. A display device that switches between a second display screen that does not include the setting information (operation guide 609) and a display screen ( The operation information of the touch monitor 12 and the input device 13 is acquired (operation information acquisition unit 706). , manages the function assignment of the input device 13 (function assignment management unit 708), and the input device 1 When 3 receives an operation, it performs processing according to the function assigned to the input device 13. The operation processing unit (707) controls the display screen to be displayed on the display device (display In a work machine comprising a control unit 710 and a control device 11, the control device 11 is the When the first display screen is displayed on the display device (touch monitor 12), When the input device 13 receives an operation, according to the function assigned to the input device 13 The process is executed and the second display screen is displayed on the display device (touch monitor 12). When in this state, if the input device 13 receives an operation, it will assign to the input device 13. Without executing processing corresponding to the function, the display screen of the display device (touch monitor 12) The system controls the system to switch from the second display screen to the first display screen.

[0064] Furthermore, the work machine (hydraulic excavator 1) displays the display screen of the display device as the first display The device has a switching unit that allows for selective switching (operator operation) between the screen and the second display screen. .

[0065] Furthermore, the control device 11 will activate if the input device 13 has not been operated for a certain period of time. In this case, the display screen of the display device is switched from the first display screen to the second display screen. Control it to change.

[0066] Furthermore, the control device 11 determines whether the work machine is operational or not (operation feasibility determination unit 7 01) When the work machine transitions from an inoperable state to an operable state, the display Control the device's display screen to switch from the first display screen to the second display screen. ru.

[0067] Furthermore, the control device 11 determines the operating state of the work machine (lever operation amount determination unit 7 02) When the work machine transitions from an inoperable state to an operating state, the display image of the display device The system controls the screen to switch from the first display screen to the second display screen.

[0068] Furthermore, the aforementioned work machine (hydraulic excavator 1) is equipped with a camera for photographing the area around the work machine. The system includes 8a, 8b, and 8c, and the first display screen and the second display screen have the following features: Camera images captured by cameras 8a, 8b, and 8c are displayed and shown on the second display screen. The display area of ​​the camera image is the same as the display area of ​​the camera image shown on the first display screen. It is larger than the measured area.

[0069] Furthermore, the input device 13 has a plurality of operation units to which the predetermined functions can each be assigned. By jog dial 13a and push buttons 13b, 13c, 13d, 13e) The control device 11 is configured such that when the second display screen is displayed on the display device, When in this state, if any of the multiple operating units accepts an operation, Switch the display screen of the display device from the second display screen to the first display screen, The display screen of 1 shows the setting information of the function assigned to the specific operation unit, along with the settings of the multiple operation units. This includes setting information for functions assigned to an operation unit different from the aforementioned specific operation unit.

[0070] Furthermore, the control device 11 transmits the display screen displayed on the display device to the input device 13. When the screen operation function for performing the operation is assigned, the input device 13 receives an operation. If it is attached, the display screen of the display device will be either the first display screen or the second display screen. Regardless of the above, in response to the operation of the input device 13, the current function assignment of the input device 13 will be determined Executes the process for the screen operation.

[0071] Furthermore, the input device 13 performs an operation to switch the function assigned to the input device 13. The system accepts operations that perform processing according to the function assigned to the input device 13. .

[0072] Furthermore, the plurality of predetermined functions are driven by the prime mover (engine, motor, etc.) that drives the work machine. ) A function to adjust the rotation speed, a function to adjust the volume of the audio in the operator's cab of the work machine, The system also includes a function to adjust the airflow of the air conditioner in the operator's cab of the work machine.

[0073] The input device 13 according to this embodiment has the current function assignment information of the input device 13 (operation guide 6 09) The first display screen including and the current function assignment information of the input device 13 (operation guide 609) It has a second display screen that does not include the current function allocation, and while the second display screen is displayed, the current function allocation is displayed. Regardless of the above, the system executes a process to transition to the first display screen in response to the operation of the input device 13. By performing this process, the operator obtains a first set of information including the current function assignment information. You can perform various setting operations after checking the display screen, so the currently assigned functions It is possible to operate without misinterpreting the input device 13. Until the operation is performed, a second display screen that does not include function assignment information will be displayed, so other display information It is possible to perform the work without compromising visibility.

[0074] Furthermore, a means (switching unit) is provided to selectively transition from the first display screen to the second display screen. By doing so, the operator no longer needs the current function assignment information at any given time. A second display screen can be shown, improving the visibility of high-priority information during work. This allows for efficient work.

[0075] Furthermore, if the input device 13 is not operated for a certain period of time, the second display screen will be displayed. By controlling it to display the current When it is determined that the function assignment information is no longer needed, the second display screen is automatically displayed. Therefore, the operator can avoid the trouble of switching to the second display screen, improving work efficiency. It is possible to do so.

[0076] Furthermore, the operating state of the work machine is determined, and when the work machine transitions from an inactive state to an operating state, By controlling the display to show a second screen, the operator can operate the work machine. When this is initiated, that is, when the situation changes to one in which the operation of the input device 13 is unlikely to occur. This automatically displays a second display screen, improving the visibility of display information other than the current function assignment information. By improving this, it becomes possible to work more efficiently.

[0077] Furthermore, the system determines the operational status of the work machine and checks if the machine has changed from an inoperable state to an operational state. When a transition occurs, the system controls the display to show the second screen, allowing the operator to perform their task. When the machine is about to start operating, that is, when it is possible to operate the input device 13 When transitioning to a lower status, the second display screen will automatically appear, showing the current function assignment information. Improving the visibility of external display information makes it possible to work more efficiently.

[0078] Furthermore, the display area of ​​the camera image displayed on the first display screen is larger than the display area of ​​the second display screen. By increasing the display area of ​​the camera image, the second function assignment information, which does not include the current function assignment information, is displayed. The display screen makes it easier to see the surroundings of the work machine, allowing for more efficient work. It is possible to conduct business.

[0079] Furthermore, the input device 13 has multiple operating parts (jog dial 13a and push button 13 If it is composed of b, 13c, 13d, 13e), then any one of the operating parts If such an operation occurs, the first operation unit, which also includes function assignment information for an operation unit different from the one that was operated, will be processed. By controlling the display screen to show the function assignment information for each operation of the control unit, Since there is no need to switch, when operating multiple control units in succession, the operation of the input device 13 This reduces the number of operations required and allows for more efficient operation of the input device.

[0080] Furthermore, there is a screen operation function that allows you to operate the display screen shown on the display device (touch monitor 12). If it is assigned to input device 13, the function assignment information is not directly displayed. However, the operator can determine from the content displayed on the screen that the current function assignment is a screen operation function. It can be inferred that the screen operation function is assigned to the input device 13. If present, you can perform screen operations regardless of whether the function assignment information is displayed or not. By doing so, it becomes possible to operate the screen efficiently.

[0081] As described above, according to this embodiment, the assigned function will not be misidentified, and the work will be performed It displays information indicating the current function assignment without reducing the visibility of other displayed information.
