[0003] Japanese Patent Publication No. 2020-104810

[0004] However, with the technology of Patent Document 1, when a user selects an item and performs an operation related to that item, if the user wants to transition to another item, the user must return to a menu screen that displays multiple selectable items and then select the other item, which is time-consuming. In other words, a menu structure is typically a hierarchical tree diagram-like structure, and when a user selects an item and performs an operation related to that item, the user transitions sequentially to the sub-structure of that item. Therefore, if the user wants to transition from a state in which the sub-structure of a certain item is displayed to a different item, the user must return to a menu screen (home screen) that displays multiple selectable items at the top of the hierarchical structure and then select the other item.

[0005] The present invention has been made to solve the problems of the prior art, and has an object to improve the operability of a display device for a work machine.

[0007] In the second display state, the display control unit may display the first operation unit for performing a selection operation of an application other than the application corresponding to the second operation unit among the plurality of applications.

[0008] In the second display state, the display control unit may display, in addition to the first operation unit and the second operation unit, a third operation unit for operating an application other than the application corresponding to the second operation unit.

[0009] The display control unit may display, as the second operation unit, a plurality of function operation members for operating a plurality of functions of the selected application, respectively.

[0010] The display control unit may display, on the second operation unit, a plurality of function operation members for respectively operating a plurality of functions of the selected and operated application, and when the operation unit for operating the application is displayed as the third operation unit, may display the same functions in an operable manner as when the operation unit for operating the application is displayed as the second operation unit.

[0011] The display control unit may display a fourth operation unit on the display screen in the second display state that accepts an operation to transition to the first display state, and when the fourth operation unit is operated, transition the display screen from the second display state to the first display state.

[0012] A work machine according to one aspect of the present invention includes the above-described display control device and a display device whose display is controlled by the display control device.

[0026] FIG. 2 shows a schematic diagram of the control block of the work machine 1. As shown in FIG. 2, the work machine 1 includes a control unit 70 and a machine memory unit 71. The control unit 70 performs various controls related to the work machine 1. The control unit 70 may be implemented by hardware formed on an integrated circuit (IC chip) or the like, or by software using a computer. In the latter case, the computer includes a storage medium on which a program, which is software that implements each function of the control unit 70, and various data related to the work machine 1 are recorded in a computer-readable manner, an arithmetic circuit such as a CPU (Central Processing Unit) that executes the program instructions, and a RAM (Random Access Memory) that expands the program and various data. The arithmetic circuit reads and executes the program from the storage medium, thereby realizing the functions of the control unit 70. The control unit 70 is connected to other devices (e.g., the prime mover Eg, the steering device 12, etc.) installed in the work machine 1 via a communication cable or an on-board communication network N such as a Controller Area Network (CAN) or FlexRay.

[0027] The machine storage unit 71 is configured with a non-volatile memory, etc. The machine storage unit 71 stores various information related to the work machine 1. The machine storage unit 71 stores an operating system and various application software.

[0028] The work machine 1 has a plurality of operation modes, and the control unit 70 can perform control based on the plurality of operation modes. For example, the machine memory unit 71 stores a conversion table that associates operation modes with control signals corresponding to the operation modes. The control unit 70 references the machine memory unit 71 in accordance with predetermined conditions and performs control based on the corresponding operation mode. In this embodiment, the work machine 1 has an auto-idle function, a crane mode function, and a slow mode function as operation modes.

[0029] The auto-idle function is a function that sets the rotation speed of the prime mover Eg to a predetermined rotation speed (idling rotation speed) when the control device 12 is not operated for a predetermined period of time while the prime mover Eg is running. The crane mode function is a function that switches the rotation speed of the prime mover Eg and the rotation speed of the swing motor MT to a predetermined rotation speed (crane mode rotation speed) suitable for lifting work when performing lifting work using a hook provided on the attachment 17. The slow mode function is a function that switches the operating speed of the work device 4 to a predetermined speed. Note that the operating modes of the work machine 1 are not limited to the modes described above, and additional or modified modes may be used as appropriate.

[0030] 3 is a diagram showing the hydraulic system of the work machine 1. The hydraulic system of the work machine 1 has service ports 41, 42 to which various hydraulic actuators can be connected, the above-mentioned hydraulic actuators C1 to C5, MT, ML, MR, control valves 31 to 40 that control the hydraulic oil supplied to these actuators, and adjustment valves 43, 44 that adjust (change) the amount of working oil supplied to the travel motors ML, MR.

[0031] The control valves 31 to 40 are connected to the hydraulic pump P1 via respective oil passages. The control valves 31 to 40 are also connected to service ports 41 and 42 and hydraulic actuators C1 to C5, MT, ML, and MR via respective oil passages.

[0032] The control valves 31 to 40 are, for example, electromagnetic three-position switching valves. More specifically, the control valves 31 to 40 are, for example, direct-acting spool-type switching valves. The control valves 31 to 40 are switched between first to third positions V1 to V3 by switching between energizing and deenergizing the solenoids. In this way, the control valves 31 to 40 control the direction, flow rate, etc. of the hydraulic oil supplied to each connected hydraulic actuator.

[0033] The adjusting valve 43 is provided in an oil passage connecting the first travel motor ML and the control valve 39, and adjusts the amount of hydraulic oil supplied from the control valve 39 to the first travel motor ML. The adjusting valve 44 is provided in an oil passage connecting the second travel motor MR and the control valve 40, and adjusts the amount of hydraulic oil supplied from the control valve 40 to the second travel motor MR.

[0034] The control unit 70 controls the control valves 31-40 and the adjustment valves 43, 44 in response to the operation of the control device 12. As shown in FIG. 1, the control device 12 is provided, for example, on control consoles 11L, 11R located on both sides of the driver's seat 6 in the width direction, and has operating members 25L, 25R, 45a-45i as shown in FIG. 3. The operating members 25L, 25R are, for example, slide switches such as a slide volume, and variable resistors that can detect the amount of movement (operation amount). The operating members 25L, 25R input signals indicating the operation amount and operation direction to the control unit 70 in response to the operation of the operator U1.

[0035] The operating members 25L, 25R include a first operating member 25L provided on the operating device 12L of the operating stand 11L and a second operating member 25R provided on the operating device 12R of the operating stand 11R. The first operating member 25L can be operated in a first operating direction (one direction) or a second operating direction (the other direction), and the second operating member 25R can be operated in a third operating direction (one direction) or a fourth operating direction (the other direction).

[0036] The operating members 45a to 45h include, for example, levers, slide switches, seesaw switches, dials, pedals, etc. The operating members 45a to 45h have sensors that detect the direction and amount of operation, and the sensors of each operating member 45a to 45h input detection signals to the control unit 70 in response to the operation of the corresponding operating member 45a to 45h.

[0037] The control unit 70 controls the corresponding control valves 31 to 40 based on signals from the operating members 25L, 25R and signals from the sensors of the operating members 45a to 45h, thereby controlling the flow rate of hydraulic oil supplied from the control valves 31 to 40 to each hydraulic actuator.

[0038] The operating member 45i is an operating member that can change the travel speed of the work machine 1 (traveling device 3) in multiple stages, separate from the operating members 45g and 45h. For example, the operating member 45i is a switch that can be set to multiple stages (e.g., three stages). The machine body memory unit 71 has stored in advance a conversion table that associates the stages (gear stages) that can be set by the operating member 45i with the control signals input to the adjusting valves 43 and 44.

[0039] In response to the operation of the operating member 45i, the sensor of the operating member 45i inputs a gear detection signal to the control unit 70. The control unit 70 references a conversion table and controls the adjusting valves 43, 44 using a control signal corresponding to the gear. This changes the amount of hydraulic oil supplied to the first traveling motor ML and the second traveling motor MR, making it possible to change the traveling speed in multiple stages.

[0040] In this embodiment, the operation of the solenoids provided in each of the control valves 31 to 40 is controlled based on signals from sensors in the operating members 25L, 25R, or the operating members 45a to 45h, but this is not limiting. For example, pilot-type control valves 31 to 40 may be used, and the pilot pressure supplied to each of the control valves 31 to 40 may be controlled by a pilot valve linked to the operating members 45a to 45h or a solenoid valve provided in a pilot oil line in accordance with the operation of the operating members 45a to 45h. Alternatively, the operation of the operating members 45a to 45h may be transmitted to each of the control valves 31 to 40 by a link mechanism or the like to control each of the control valves 31 to 40.

[0041] 2, the control unit 70 may also have a flow rate setting unit 70a that variably sets the maximum flow rate level (maximum value of the flow rate of the hydraulic oil) of the hydraulic oil supplied to or discharged from the control valves 31, 32 to the attachment 17. The flow rate setting unit 70a is a program stored in a storage medium of the control unit 70, and variably sets the maximum flow rate level using, for example, a predetermined control map. For example, the flow rate setting unit 70a can set each of the maximum flow rate levels (first to fourth supply flow rates) when the operating members 25L, 25R are operated by a predetermined stroke or more in each operating direction (first to fourth operating directions).

The first display control device 72A and the second display control device 72B may be part of the control unit 70, or may be provided separately from the control unit 70 and may exchange various information with the control unit 70.

[0066] As shown in FIG. 2, the first display control device 72A has a display control unit (controller, first display control unit) 72A1, an operation reception unit (event handler) 72A2, and a storage unit 72A3.

[0067] The controller 72A1 performs various controls related to the first display device 60A, and mainly controls the first display device 60A to display information related to the work machine 1. The control unit 70 inputs to the controller 72A1 information stored in the machine memory unit 71 and information acquired from the detection device 73, the abnormality detection unit 70b, and the imaging device 26. The controller 72A1 displays the information acquired from the control unit 70 on the first display screen 61A of the first display device 60A.

[0068] The event handler 72A2 detects operations performed by the worker U1 on the first display device 60A, inputs instruction signals to the control unit 70 to perform operations related to the work machine 1, and inputs instruction signals related to control of the first display device 60A to the controller 72A1. The control unit 70 controls various operations related to the work machine 1 based on the instruction signals input by the event handler 72A2.

[0069] The storage unit 72A3 stores various information related to the first display device 60A.

[0070] As shown in FIG. 2, the second display control device 72B has a display control unit (controller, second display control unit) 72B1, an operation reception unit (event handler) 72B2, and a storage unit 72B3.

[0071] The controller 72B1 performs various controls related to the second display device 60B and causes the second display device 60B to display an operation unit 120 that mainly receives operations for the device X provided in the work machine 1 (in other words, for inputting operations). The operation unit 120 is an electronic interface. In other words, it can be said that the work machine 1 of this embodiment is equipped with an operation device (second display device) 60B that includes the operation unit 120 and the operating tool 62.

[0072] 10A , the operation unit 120 is arranged in a second upper region 110A above the second display screen 61B. In addition to the second upper region 110A, the operation unit 120 is also arranged in a third display region 110C in the second lower region 110B between the pair of operation tools 62. That is, the controller 72B1 displays the operation unit 120 in the second upper region 110A of the second display screen 61B, which is a region separate from the region in which the operation tools 62 are provided, and in the region 110C between the pair of operation tools 62 in the second lower region 110B.

[0073] The event handler 72B2 detects operations performed by the worker U1 on the second display device 60B, inputs instruction signals to the control unit 70 mainly for operating the equipment of the work machine 1, and inputs instruction signals related to the control of the second display device 60B to the controller 72B1. The event handler 72B2 can detect the operation amount, rotation direction, and operation speed of the operating tool 62, as well as the operation of the operating unit 120. The control unit 70 controls various operations related to the work machine 1 based on the instruction signals input by the event handler 72B2.

[0074] The storage unit 72B3 stores various information related to the second display device 60B.

[0075] Below, a specific example will be described in which the control unit 70 operates the device X based on an instruction signal input by the event handler 72B2. For example, when the worker U1 operates the operation unit 120 related to the air conditioner 74 displayed on the second display screen 61B, the event handler 72B2 detects the operation and inputs an instruction signal to operate the air conditioner 74 to the control unit 70. Based on this instruction signal, the control unit 70 performs control to operate the air conditioner 74 (for example, switching between blowing (ON) and stopping (OFF) conditioned air from the blowing units 52A and 52B).

[0076] Furthermore, when the worker U1 operates the operation unit 120 related to the sound device 75 displayed on the second display screen 61B, the event handler 72B2 detects the operation and inputs an instruction signal to activate the sound device 75 to the control unit 70. Based on this instruction signal, the control unit 70 performs control to activate the sound device 75 (for example, converting radio wave information or music information into an electrical signal and outputting it to a speaker).

[0077] Furthermore, when the worker U1 operates the operation unit 120 related to the wiper device 76 displayed on the second display screen 61B, the event handler 72B2 detects the operation and inputs an instruction signal for operating the wiper device 76 to the control unit 70. Based on this instruction signal, the control unit 70 performs control to operate the wiper device 76 (for example, switching between operating (ON) and stopping (OFF) the wiping of water droplets).

[0078] Furthermore, when the worker U1 operates the operation unit 120 related to the defogging device 77 displayed on the second display screen 61B, the event handler 72B2 detects the operation and inputs an instruction signal to operate the defogging device 77 to the control unit 70. Based on this instruction signal, the control unit 70 performs control to operate the defogging device 77 (air conditioner 74) (for example, switching between blowing (ON) and stopping (OFF) conditioned air from the blowing units 53A and 53B).

[0079] Furthermore, when the worker U1 operates the operation unit 120 related to the locking device 78 displayed on the second display screen 61B, the event handler 72B2 detects the operation and inputs an instruction signal for activating the locking device 78 to the control unit 70. Furthermore, when the worker U1 operates the supplementary information 92 indicating the operating status of the locking device 78 displayed on the display screen 61A (first display screen 61A), the event handler 72A2 detects the operation and inputs an instruction signal for activating the locking device 78 to the control unit 70. The control unit 70 performs control for activating the locking device 78 (for example, locking and unlocking) based on these instruction signals.

[0080] Furthermore, when the worker U1 operates the operation unit 120 related to the lighting device 30 displayed on the second display screen 61B, the event handler 72B2 detects the operation and inputs an instruction signal to activate the lighting device 30 to the control unit 70. Based on this instruction signal, the control unit 70 controls the operation of the lighting device 30 (for example, turning it on and off).

[0081] Furthermore, when the worker U1 operates the operation unit 120 related to the crane mode displayed on the second display screen 61B, the event handler 72B2 detects the operation and inputs an instruction signal for activation of the crane mode to the control unit 70. Based on this instruction signal, the control unit 70 performs control to change the rotation speed of the prime mover Eg, etc. to a predetermined rotation speed, and control to activate (turn on or off) the rotating light 22.

[0082] In the above example, the control unit 70 activates device X based on an instruction signal from the event handler 72B2, but the control unit 70 may also activate device X based on an instruction signal from the event handler 72A2. Specifically, the event handler 72A2 detects an operation on supplemental information 92, which will be described later, and the control unit 70 activates device X based on the instruction signal from the event handler 72A2.

[0083] The operating status (operating situation) of each device X is displayed on the display devices 60A and 60B. In this case, the control unit 70 detects the operating status of each device X and inputs it as the current operating status to the controllers 72A1 and 72B1. The controllers 72A1 and 72B1 then display the operating status on the display devices 60A and 60B.

[0084] Hereinafter, the screens that the first display control device 72A (controller 72A1) causes to be displayed on the first display screen 61A of the first display device 60A will be described with reference to FIGS.

[0085] 5 and 6, the controller 72A1 displays information about the work machine 1 on a first display screen (display screen) 61A of the first display device 60A. The controller 72A1 simultaneously displays different information in a first upper area (upper area) 80A on the upper side of the first display screen 61A and a first lower area (lower area) 80B on the lower side. The upper area 80A is larger than the lower area 80B.

[0086] The controller 72A1 displays, as information relating to the work machine 1, environmental information 100 ( FIG. 5 ) indicating the environment around the work machine 1 and / or guidance information 101 ( FIG. 6 ) for the work machine 1 in the first upper area 80A, and status information 90 indicating the status of the work machine 1 in the first lower area 80B. In this embodiment, the environmental information 100 is a plurality of captured images 102 acquired by a plurality of imaging devices 26A, 26B provided on the work machine 1. These are displayed on the first display device 60A. The guidance information 101 for the work machine 1 is information that assists the operator U1 in operating the work machine 1.

[0087] The controller 72A1 displays a first switching operation unit 103 and a second switching operation unit 104 in the upper part of the upper region 80A. The first switching operation unit 103 accepts an operation to switch the display of the multiple captured images 102 acquired by the multiple imaging devices 26A, 26B. When the first switching operation unit 103 is operated, the event handler 72A2 accepts an operation to switch the display of the multiple captured images 102.

[0088] The second switching operation unit 104 accepts an operation to switch the display between the environmental information 100 and / or the guidance information 101 of the work machine 1 and the setting operation unit 105. When the second switching operation unit 104 is operated, the event handler 72A2 accepts an input of an operation to switch the display between the environmental information 100 and / or the guidance information 101 of the work machine 1 and the setting operation unit 105, and the controller 72A1 displays the setting operation unit 105 in the upper area 80A. The setting operation unit 105 accepts an input of setting information for the work machine 1.

[0089] 7 , the controller 72A1 displays, as status information 90 in the lower region 80B of the first display screen 61A, an overhead image 91 in which the work machine 1 is viewed from above, and supplemental information 92 that supplements the overhead image 91 and indicates the status of one or more devices X included in the work machine 1. The status information 90 includes the overhead image 91 and the supplemental information 92. The controller 72A1 displays the overhead image 91 in a region 80C that is the center of the lower region 80B.

[0090] For example, as shown in Fig. 7 , the supplemental information 92 indicates the operation status of the lighting device 30, the rotating light 22, the wiper device 76, the defogging device 77, and the locking device 78. The position of the supplemental information 92 corresponds to the position of each device X in the overhead image 91. For example, as shown in Fig. 7 , the supplemental information 92 is a graphic that is displayed superimposed on the overhead image 91. Note that the shape of the supplemental information 92 is not limited. For example, the supplemental information 92 may be a graphic in the shape of a speech bubble, and the position of the device X on the aircraft 2 may be indicated by placing a speech bubble line on the overhead image 91.

[0091] The controller 72A1 causes the first display device 60A to display the operating status of the device X input by the control unit 70 as supplemental information 92. The supplemental information 92 indicates the operating status of each device X by changing the display format. For example, the controller 72A1 switches between displaying and hiding each piece of supplemental information 92 depending on the status of each device X.

[0092] The controller 72A1 displays the corresponding supplemental information 92 when the lighting device 30 and the rotating light 22 are in an on state (lighting status), and does not display the supplemental information 92 when the lighting device 30 and the rotating light 22 are in an off state. The supplemental information 92a to 92g corresponds to the boom light 18, the headlight 19L, the headlight 19R, the side light 20L, the side light 20R, the taillight 21, and the rotating light 22, respectively.

[0093] The controller 72A1 displays the corresponding supplemental information 92 when the wiper device 76 is in an activated state (ON), and does not display the corresponding supplemental information 92 when the wiper device 76 is in an inactivated state (OFF). The supplemental information 92h and 92i correspond to the front wiper 76a and rear wiper 76b of the wiper device 76, respectively.

[0094] The controller 72A1 displays the corresponding supplemental information 92 when the defogging device 77 is in the blowing (ON) state, and does not display the supplemental information 92 when the defogging device 77 is in the stopped (OFF) state. As shown in FIG. 4 , the supplemental information 92j and 92k correspond to the blowing portions 53A and 53B of the defogging device 77, respectively.

[0095] The controller 72A1 displays the corresponding supplemental information 92l when the state (locking status) of the locking device 78 is locked, and does not display the supplemental information 92l when the state (locking status) of the locking device 78 is unlocked.

[0096] It should be noted that the display of the supplemental information 92 only needs to indicate the state of device X, and the controller 72A1 may change the display color or illuminance of the supplemental information 92 depending on the state of device X. For example, if the lighting device 30 is a device whose illuminance can be changed, the illuminance of the supplemental information 92 may be changed based on the illuminance of the lighting device 30.

[0097] The controller 72A1 displays first information 93 related to the machine body 2 of the work machine 1 on one side of the width direction of the overhead image 91 and the supplemental information 92 in the lower area 80B. The status information 90 includes the first information 93.

[0098] 7 , the controller 72A1 displays first information 93 in an area 80D that is on one side of the width direction (the right side) of the area 80C in which the overhead image 91 and the supplemental information 92 are displayed. The first information 93 includes information about the machine 2 (traveling device 3) acquired by the detection device 73. The first information 93 includes one or more of the remaining amount of fuel, the state of charge of the battery, the rotation speed of the prime mover Eg, the operating state of the auto-idle function, and the gear shift state of the traveling device 3 (information about the gear position).

[0099] The control unit 70 inputs to the first display control device 72A information on the current remaining amount of fuel and information on the rotation speed of the prime mover Eg, which are acquired by the detection device 73, and the gear shift state of the traveling device 3. The controller 72A1 converts this information input by the control unit 70 into images 93a to 93c, which are displayable information, and displays them in the area 80D.

[0100] In addition, when the prime mover Eg is an electric motor, the controller 72A1 may display an image 93a indicating the charge state of the battery as the first information 93 in the area 80D.

[0101] Furthermore, the first information 93 is not limited to the above-described images 93a to 93c, and may be other information. For example, the control unit 70 may input the operating status of the auto idle function (whether the auto idle function is being executed or not) to the first display control device 72A, and the controller 72A1 may display the image 93d in the area 80D when the auto idle function is being executed, and may hide the image 93d when the auto idle function is not being executed.

[0102] The controller 72A1 displays second information 94 related to the work device 4 of the work implement 1 in the other widthwise portion of the lower area 80B between the overhead image 91 and the supplemental information 92. The status information 90 includes the second information 94. The second information 94 includes one or more of the type of attachment 17 attached to the work device 4, the operation mode of the work device 4, the setting status related to the operation restrictions of the work device 4, and the flow rate setting status of the work device 4.

[0103] 7 , the controller 72A1 displays second information 94 in an area 80E that is the other widthwise side (leftward) of the area 80C that displays the overhead image 91 and the supplemental information 92. The second information 94 includes information 94a about the operation mode or operation restrictions of the work device 4, type information 94b of the attachment 17, flow rate setting mode information 94c of the attachment 17, and information 94e about the operation mode of the work device 4.

[0104] More specifically, the control unit 70 inputs information regarding the operation restrictions of the working device 4 to the first display control device 72A. The controller 72A1 displays the information regarding the operation restrictions in the area 80E. For example, when there is a respective operation restriction, the controller 72A1 displays images 94a1 to 94a3 corresponding to the operation restriction in the area 80E, and hides images 94a1 to 94a3 corresponding to the case when there is no operation restriction. The information regarding the operation restrictions of the working device 4 includes a movement restriction in the height direction of the boom 15, a movement restriction in the arm dump direction of the arm 16, a movement restriction in the arm crowding direction of the arm 16, etc.

[0105] The control unit 70 inputs the type of attachment 17 to the first display control device 72A, and the controller 72A1 displays an icon image 94b corresponding to the type of attachment 17 (in Figure 7, the icon image corresponding to bucket X1) in the area 80E.

[0106] The control unit 70 inputs the flow rate setting mode of the attachment 17 acquired by the flow rate setting unit 70a to the first display control device 72A, and the controller 72A1 displays an icon image 94c corresponding to the flow rate setting mode in the area 80E.

[0107] The control unit 70 inputs the operation mode of the working device 4 to the first display control device 72A, and the controller 72A1 displays information 94e relating to the operation mode in the area 80. For example, if the operation mode of the working device 4 is the slow mode, the controller 72A1 displays the information 94e "Slow Mode." If the operation mode of the working device 4 is not the slow mode, the controller 72A1 hides the information 94e.

[0108] 5 , the controller 72A1 displays environmental information 100 in the upper region 80A, and displays, as the environmental information 100, a captured image 102 acquired by the imaging device 26 provided in the work machine 1. Specifically, the control unit 70 controls the imaging device 26 to acquire the captured image 102. The control unit 70 inputs the captured image 102 as the environmental information 100 to the first display control device 72A. The controller 72A1 displays the captured image 102 input by the control unit 70 in the upper region 80A of the first display screen 61A of the first display device 60A.

[0109] The controller 72A1 displays, at the top of the upper region 80A of the first display screen 61A, a first switching operation unit 103 that accepts an operation to switch the display of multiple captured images 102 (102A, 102B) acquired by multiple imaging devices 26 (26A, 26B) provided in the work machine 1. The controller 72A1 displays the first switching operation unit 103 in the upper region 80A where the captured images 102 are displayed. The first switching operation unit 103 is displayed at the top of the upper region 80A of the first display screen 61A.

[0110] Specifically, a circular list indicating the imaging devices 26 to be displayed is stored in advance in the storage unit 72A3. When the event handler 72A2 receives an input operation from the first switching operation unit 103, it references the circular list in the storage unit 72A3 and inputs an instruction signal specifying the imaging device 26 to the control unit 70. The circular list may define an instruction signal for displaying each of the imaging devices 26A and 26B individually, or may define an instruction signal for displaying multiple imaging devices 26A and 26B simultaneously. It may also define that guidance information 101, which will be described later, is to be displayed.

[0111] When the operator U1 operates the first switching operation unit 103 while the controller 72A1 is displaying the captured image 102A from the imaging device 26A, the event handler 72A2 accepts the operation on the first switching operation unit 103. The event handler 72A2 references the circular list and inputs an instruction signal to the control unit 70 to acquire the captured image 102B from the imaging device 26 (26B). The control unit 70 inputs the captured image 102B to the first display control device 72A based on the instruction signal, and the controller 72A1 displays the input captured image 102B in the upper area 80A.

[0112] As shown in Fig. 6 , the controller 72A1 displays guidance information 101 for the work machine 1 in the first upper area 80A as information related to the work machine 1. For example, as shown in Fig. 6 , the guidance information 101 includes a posture image 101a indicating the current position and posture of the work machine 1 (the boom 15, the arm 16, and the attachment 17) and a cross-sectional image 101b of the construction data. The guidance information 101 starts to be displayed in the upper area 80A when the worker U1 performs a predetermined operation on the first display device 60A. Alternatively, the worker U1 may start displaying the guidance information 101 by operating the first switching operation unit 103.

[0113] Specifically, the control unit 70 detects the current positions and attitudes of the boom 15, the arm 16, and the attachment 17, and inputs them to the first display control device 72A. For example, the control unit 70 detects the current positions and attitudes of the boom 15, the arm 16, and the attachment 17 based on information acquired from the detection device 73.

[0114] The controller 72A1 converts the input positions and attitudes of the boom 15, arm 16, and attachment 17 into an attitude image 101a, which is information that can be displayed on the first display screen 61A. The control unit 70 also inputs the construction data stored in the machine memory unit 71 to the first display control device 72A. The construction data is, for example, data that indicates the state of the construction site after work is completed.

[0115] The controller 72A1 converts the input construction data into a cross-sectional image 101b. The controller 72A1 displays guidance information 101 including the attitude image 101a and the cross-sectional image 101b in the upper region 80A of the first display screen 61A of the first display device 60A.

[0116] The display format of the guidance information 101 is not limited to the above configuration, and any conventionally known display format can be used.Furthermore, the method of acquiring the current positions and postures of the boom 15, arm 16, and attachment 17, and the construction data, is not limited to the above configuration, and any conventionally known acquisition format can be used.

[0117] The controller 72A1 may display the status information 90 in the lower region 80B of the first display screen 61A while simultaneously displaying the environmental information 100 in the upper region 80A. The controller 72A1 may also display the status information 90 in the lower region 80B of the first display screen 61A while simultaneously displaying the guidance information 101 in the upper region 80A. The controller 72A1 may also display the status information 90 in the lower region 80B of the first display screen 61A while simultaneously displaying the status information 90 and the guidance information 101 in the upper region 80A.

[0118] As shown in FIG. 5 , when an abnormality occurs, the controller 72A1 displays warning information 81 related to a warning condition corresponding to the abnormality. The warning information 81 includes a message image 81a indicating the content of the warning condition and an icon image 81b indicating the type of the warning condition. When an abnormality occurs, the controller 72A1 displays the warning information 81 between the first upper region 80A and the first lower region 80B or in the first lower region 80B. The message image 81a is a text image that can display the content of the warning information 81 on the display screens 61A and 61B. The icon image 81b is an abbreviated or simplified icon that evokes the content of the warning information 81 and indicates the type of the warning information 81. The storage unit 72A3 previously stores a table that associates message images 81a corresponding to the warning information 81 with icon images 81b.

[0119] When the abnormality detection unit 70b detects warning information 81 corresponding to a warning condition, the control unit 70 inputs the warning information 81 to the controller 72A1 of the first display control device 72A. The controller 72A1 refers to the storage unit 72A3 and converts the input warning information 81 into a message image 81a and an icon image 81b. The controller 72A1 displays the message image 81a and the icon image 81b on the first display screen 61A. The message image 81a is arranged in an area 80F in the upper area 80A, which is close to the lower area 80B. The icon image 81b is displayed in the lower area 80B.

[0120] The display color, display size, and display time of the message image 81a and the icon image 81b may be changed depending on the warning condition. Furthermore, the time for which the message image 81a is displayed on the first display screen 61A may be different from the time for which the icon image 81b is displayed on the first display screen 61A. For example, the controller 72A1 displays the message image 81a for a predetermined time or longer and then hides the message image 81a. Meanwhile, the controller 72A1 continues to display the icon image 81b while the abnormality detection unit 70b detects a warning condition.

[0121] 8 , the controller 72A1 displays in the upper region 80A a setting operation unit 105 that accepts input of setting information for the work machine 1, instead of environmental information 100 and / or guidance information 101 for the work machine 1. The setting operation unit 105 allows various settings related to the display devices 60A, 60B and setting operations related to maintenance of the work machine 1. The setting operation unit 105 includes a setting category selection unit 106 that allows selection of a category of setting information, and a setting information input unit 107.

[0122] For example, as shown in FIG. 8 , when worker U1 operates the “Display” category (106a) in the setting category selection unit 106, the controller 72A1 displays the setting information input unit 107a corresponding to “Display.” Furthermore, when worker U1 operates “Display mode: Day” (107a1), the event handler 72A2 references the storage unit 72A3 and acquires the illuminance setting values ​​of the first display device 60A and the second display device 60B corresponding to “Display mode: Day.” The event handler 72A2 inputs the illuminance setting value of the first display device 60A to the controller 72A1. The controller 72A1 controls the illuminance of the first display device 60A based on the input setting value. The event handler 72A2 inputs the illuminance setting value to the second display control device 72B. The second display control device 72B (controller 72B1) controls the illuminance of the second display device 60B based on the input setting value.

[0123] 5, the controller 72A1 displays in the upper region 80A a second switching operation unit 104 that accepts an operation to switch the display between the environmental information 100 and / or the guidance information 101 for the work machine 1 and the setting operation unit 105. When the worker U1 operates the second switching operation unit 104, the event handler 72A2 inputs an instruction signal to the controller 72A1 to display the setting operation unit 105. The controller 72A1 displays the setting operation unit 105 in the upper region 80A of the first display screen 61A.

[0124] The following describes the screen that the second display control device 72B (controller 72B1) causes to be displayed on the second display screen 61B of the second display device 60B.

[0125] The second display control device 72B accepts operations of a plurality of applications related to the work machine 1. The plurality of applications include, for example, a first application (air conditioning application) that performs operations related to the air conditioning device 74, a second application (music application) that performs operations related to the sound device 75, a third application (flow rate setting application) that performs operations to set flow rates to the first service port 41 and the second service port 42, and the like.

As shown in FIG. 11A , the application icon 121a is an icon indicating a first application, the application icon 121b is an icon indicating a second application, and the application icon 121c is an icon indicating a third application.

[0128] 11B and 11C, in the second display state S2, the controller 72B1 displays on the second display screen 61B a second operation unit 122 and a first operation unit 121 for operating the application to be operated. As shown in FIGS. 10A, 11B, and 11C, the controller 72B1 displays the second operation unit 122 in a second display area 110D, which is an upper area of ​​the second display screen 61B. The second operation unit 122 is a screen on which the application can be operated. For example, as shown in each of FIGS. 11B to 11D, the application screen 122a (FIG. 11B) is an operation screen for operating the first application, the application screen 122b (FIG. 11C) is an operation screen for operating the second application, and the application screen 122c (FIG. 11D) is an operation screen for operating the third application. The controller 72B1 displays the first operation unit 121 in a first display area 110E, which is an upper area of ​​the second display screen 61B. In the second display state S2, the controller 72B1 displays a fourth operation unit 124 for accepting an operation to transition to the first display state S1 (home screen Q1). For example, the fourth operation unit 124 is a home icon, and as shown in FIG. 11B , is arranged alongside the first operation unit 121 in the first display area 110E. That is, when an application selection operation is performed, the controller 72B1 displays the first operation unit 121, the second operation unit 122, and the fourth operation unit 124 on the second display screen 61B as the second display state S2.

[0129] Next, the state transition of the second display screen 61B will be described.

[0130] 11A to 11D, the controller 72B1 displays on the second display screen 61B of the second display device 60B a first operation unit 121 (application icons 121a to 121c) that accepts a selection operation of an application to be operated from among a plurality of applications related to the work machine 1. When an application to be operated is selected on the first operation unit 121 (when an operation to select an application is performed), the controller 72B1 transitions the second display screen 61B to a second display state S2 for operating the application.

[0131] When worker U1 operates one of the application icons 121a to 121c included in the first operation unit 121, the second display screen 61B transitions to the second display state S2 for operating the application touched by worker U1.

[0132] In the second display state S2, the controller 72B1 displays a first operation unit 121 for selecting an application from among the plurality of applications other than the application corresponding to the second operation unit 122. The controller 72B1 displays app icons 121a to 121c other than the application selected by the worker U1 as the first operation unit 121 on the second display screen 61B.

[0133] The controller 72B1 can transition the second display screen 61B to the first display state S1. The controller 72B1 displays a fourth operation unit 124, which accepts an operation for transitioning to the first display state S1, on the second display screen 61B in the second display state S2, and transitions the second display screen 61B from the second display state S2 to the first display state S1 when the fourth operation unit 124 is operated. When transitioning from the second display state S2 to the first display state S1, the controller 72B1 hides the second operation unit 122 from the second display area 110D.

[0134] FIG. 9 is a state transition diagram of the second display screen 61B. Events E1 to E4 represent operations by the worker U1 that trigger the controller 72B1 to transition the screen of the second display screen 61B. When any of events E1 to E4 occurs, the controller 72B1 transitions the screen of the second display screen 61B. Events E1 to E4 indicate that the worker U1 operates the application icon 121a (air conditioning), the application icon 121b (music), the application icon 121c (AUX), or the fourth operation unit 124 (home icon), respectively. When event E1 occurs, the controller 72B1 transitions the second display screen 61B to the first setting screen Q2, which is the second display state S2. When event E2 occurs, the controller 72B1 transitions the second display screen 61B to the second setting screen Q3, which is the second display state S2. In addition, when event E3 occurs, the controller 72B1 transitions the second display screen 61B to the third setting screen Q4, which is the second display state S2, and when event E4 occurs, the controller 72B1 transitions the second display screen 61B to the home screen Q1, which is the first display state S1.

The controller 72B1 also causes the first display area 110E of the second display screen 61B to display app icons 121b, 121c, etc. as the first operation unit 121. When the second display screen 61B is displaying the first setting screen Q2, the controller 72B1 does not display the app icon 121a that is the application, but instead displays the fourth operation unit 124 on the second display screen 61B.

[0137] FIG. 11C shows the second setting screen Q3 in the second display state S2. When the worker U1 operates the application icon 121b (FIGS. 11A, 11B, and 11D) (event E2 occurs), the controller 72B1 displays the second setting screen Q3 on the second display screen 61B. The controller 72B1 displays an application screen 122b, which allows the user to operate the second application, as the second operation unit 122 in the second display area 110D of the second display screen 61B. The controller 72B1 also displays application icons 121a, 121c, and the like as the first operation unit 121 in the first display area 110E of the second display screen 61B. When the second display screen 61B displays the second setting screen Q3, the controller 72B1 does not display the application icon 121b, which is the application, and instead displays the fourth operation unit 124 on the second display screen 61B.

[0138] FIG. 11D shows the third setting screen Q4 in the second display state S2. When the worker U1 operates the application icon 121c (FIGS. 11A, 11B, and 11D) (event E3 occurs), the controller 72B1 displays the third setting screen Q4 on the second display screen 61B. The controller 72B1 displays an application screen 122c, which allows the user to operate the third application, as the second operation unit 122 in the second display area 110D of the second display screen 61B. The controller 72B1 also displays application icons 121a, 121b, and the like as the first operation unit 121 in the first display area 110E of the second display screen 61B. When the second display screen 61B displays the third setting screen Q4, the controller 72B1 does not display the application icon 121c, which is the application, and instead displays the fourth operation unit 124 on the second display screen 61B.

[0139] 11A shows the home screen Q1 in the first display state S1. When the worker U1 operates the fourth operation unit 124 (FIGS. 11B, 11C, and 11D) (event E4 occurs), the controller 72B1 displays the home screen Q1 on the second display screen 61B. The controller 72B1 does not display the fourth operation unit 124 in the area 110A of the second display screen 61B, but instead displays the application icons 121a, 121b, and 121c as the first operation unit 121.

[0140] As described above, when the worker U1 operates the first operation unit 121 or the fourth operation unit 124, the controller 72B1 can switch (transition) between the home screen Q1 in the first display state S1 and the first setting screen Q2, the second setting screen Q3, and the third setting screen Q4 in the second display state S2, and display them on the second display screen 61B. In addition, switching between the first setting screen Q2, the second setting screen Q3, and the third setting screen Q4 can be performed without using the home screen Q1.

[0141] The second operation unit 122 and the third operation unit 123 operated on the second display screen 61B will be described in detail below.

[0142] As shown in FIGS. 10A and 11B to 11D, in the second display state S2 (first setting screen Q2 to third setting screen Q4), the controller 72B1 displays a third operation unit 123 for operating application functions in the third display area 110C of the second display screen 61B in addition to the first operation unit 121 and the second operation unit 122. As shown in FIGS. 10A and 11A, in the first display state S1 (home screen Q1), the controller 72B1 displays a third operation unit 123 in the third display area 110C in addition to the first operation unit 121. The third operation unit 123 includes function icons (images) 123a to 123o representing application functions. The function icons 123a to 123o for operating application functions are arranged side by side in the third display area 110C.

[0143] The function icon 123a indicates a function of switching between starting (ON) and stopping (OFF) the operation of the air conditioner 74. The function icon 123b indicates a function of switching between starting (ON) the operation of the air conditioner 74 to maximize the volume of conditioned air and stopping (OFF) the operation of the air conditioner 74. The function icon 123c indicates a function of switching between inside air circulation and outside air introduction by the air conditioner 74.

[0150] The function icon 123n indicates a function of switching the rotating light 22 between operation (ON) and stop (OFF).

[0151] The function icon 123o indicates a function of switching the locking device 78 between locking and unlocking.

[0152] The controller 72B1 can display, on the third operation unit 123, a function different from the application displayed on the second operation unit 122. For example, as shown in Fig. 11C (second setting screen Q3), the controller 72A1 displays, as the second operation unit 122, an application screen 122b for operating the second application, and displays a function icon 123a (third operation unit 123) for operating the air conditioner 74, which is a function of the first application, to start (ON) and stop (OFF) the operation of the air conditioner 74.

[0153] The controller 72A1 may change the display of the third operation unit 123 (function icons 123a to 123o) depending on the setting screen. For example, as shown in FIG. 11A (home screen Q1), the controller 72A1 displays the function icon 123o. As shown in FIG. 12B (first setting screen Q2), the controller 72A1 hides the function icon 123o.

[0154] The controller 72B1 causes the second operation unit 122 to display a plurality of function operation members (images) for operating each of a plurality of functions of the selected application.

[0155] 11B, the controller 72B1 displays function operation members 122a1 and 122a2 on the application screen 122a. The function operation member 122a1 indicates an operation for switching between starting (ON) and stopping (OFF) the operation of the air conditioner 74. The function operation member 122a1 indicates an operation for switching between starting (ON) and stopping (OFF) automatic control of the air conditioner 74.

[0156] 11C, the controller 72B1 displays function operation members 122b1 and 122b2 on the application screen 122b. The function operation member 122b1 indicates an operation for switching the radio reception frequency of the audio device 75. The function operation member 122b2 indicates an operation for switching the operation of the audio device 75 to one of AM broadcasting, FM broadcasting, and connection to an external terminal.

[0157] 11D, the controller 72B1 displays function operation members 122c1 and 122c2 on the application screen 122c. The operation of the function operation members 122c1 and 122c2 will be described later.

[0158] The controller 72B1 causes the third operation unit 123 to display the same functions as when the operation unit 120 for operating the selected application is displayed as the second operation unit 122. For example, as shown in FIG. 11B (first setting screen Q2), the function operation member 122a1 of the second operation unit 122 and the function icon 123a of the third operation unit 123 indicate the function of switching between operation start (ON) and operation stop (OFF) of the same air conditioner 74. The controller 72B1 simultaneously displays the function operation member 122a1 and the function icon 123a on the second display screen 61B.

[0159] The controller 72B1 may also display, on the second operation unit 122, a function operation member for operating the same function as the operation content (function) accepted by the operation tool 62. For example, as shown in Fig. 11C (second setting screen Q3), the function operation member 122c1 and the operation tool 62L indicate a function for switching the radio reception frequency.

[0160] The following describes operations accepted by the event handler 72B2. The event handler 72B2 accepts operation inputs related to device X. Specifically, when worker U1 operates the operation units 120 (first operation unit 121, second operation unit 122, third operation unit 123, and fourth operation unit 124), the event handler 72B2 detects that the operation units 120 have been operated (that an event has occurred). Upon detecting that the operation units 120 have been operated, the event handler 72B2 inputs, to the control unit 70 or the controller 72B1, an instruction signal for performing operation processing on device X corresponding to the operation units 120.

[0161] Specifically, when the worker U1 operates the application icon 121a (FIG. 5), the event handler 72B2 detects that the application icon 121a has been operated. Subsequently, the event handler 72B2 inputs an instruction signal to the controller 72B1 to display the first setting screen Q2. The controller 72B1 then displays the first setting screen Q2 (FIG. 11B) on the second display screen 61B.

[0162] Furthermore, when the worker U1 operates the function icon 123a, the event handler 72B2 detects that the function icon 123a has been operated. Subsequently, the event handler 72B2 inputs an instruction signal for switching the air conditioner 74 between operation start (ON) and operation stop (OFF) to the control unit 70. The control unit 70 controls the operation of the air conditioner 74 in accordance with the instruction signal input by the event handler 72B2.

[0163] Furthermore, when the operator U1 operates the function operation member 122a1 on the first setting screen Q2, the event handler 72B2 detects that the function operation member 122a1 has been operated. Subsequently, the event handler 72B2 inputs an instruction signal to the control unit 70 to switch between blowing (ON) and stopping (OFF) conditioned air from the blowout unit 52A (FIG. 4). The control unit 70 controls the operation of the air conditioner 74 in response to the instruction signal input by the event handler 72B2.

[0164] In addition to the operation unit 120, the event handler 72B2 accepts operations on an operation tool 62 provided on the second display screen 61B as operation inputs related to the device X. The operation target of the operation tool 62 can be selectively switched (changed) among the devices X in accordance with operations on the operation unit 120 (first operation unit 121, second operation unit 122, third operation unit 123, fourth operation unit 124). The controller 72B1 displays second images (application icons 121a to 121c, function operation members 122a1, 122a2, 122b1, 122b2, 122c1, 122c2, function icons 123a to 123o) indicating the operation targets (plural devices X) as the operation unit 120 on the second display image (second display screen) 61B. When the operation unit 120 is operated (when the second image is selected), the event handler 72B2 changes the operation input received by the operation tool 62 according to the application selected by the operation unit 120 or the device X to be operated.

[0165] When the event handler 72B2 changes the operation target of the operation tool 62, it inputs to the controller 72A1 an instruction signal to change the display of the operation target of the operation tool 62. The controller 72A1 changes the display indicating the operation target of the operation tool 62 on the second display screen 61B based on the instruction signal input from the event handler 72B2 (in accordance with the selected and operated device X).

[0166] 11D , the controller 72A1 displays first images 62L1, 62L2, 62R1, and 62R2 indicating operation contents (operation targets) accepted by the operation tool 62 near the operation tool 62. When an instruction signal is input from the event handler 72B2, the controller 72B1 controls to switch (change) the display of the first images 62L1, 62L2, 62R1, and 62R2 located near the operation tool 62 based on the instruction signal.

[0167] As described above, a through-hole is formed in the center of the operating tool 62, allowing the worker U1 to view the display on the second display screen 61B of the inside of the tube of the operating tool 62. Specifically, the center of the operating tool 62L is the area 110F ( FIG. 10A ), allowing the worker U1 to view the display in this area 110F. The controller 72B1 displays the first image 62L1, which indicates the operation target to be received by the operating tool 62L, in the area 110F of the second display screen 61B.

[0168] The center of the operating tool 62R is an area 110G (FIG. 10A), and the operator U1 can see the area 110G. The controller 72B1 displays a first image 62R1 indicating an operation target to be received by the operating tool 62R in the area 110G of the second display screen 61B.

[0169] 10A, 11A (home screen Q1), and 11B (first setting screen Q2), the controller 72B1 displays a first image 62L1 indicating an operation for adjusting the airflow volume in the area 110F where the operating tool 62L is arranged. The controller 72B1 displays a first image 62R1 indicating an operation for adjusting the temperature in the area 110G where the operating tool 62R is arranged.

[0170] The controller 72B1 may display current information about functions accepted by the operating tool 62, along with the target to be operated by the operating tool 62. For example, as shown in Fig. 11A (home screen Q1) and Fig. 11B (first setting screen Q2), the controller 72B1 displays information about the current temperature setting set in the air conditioner 74 as a first image 62R1 in an area 110F of the second display screen 61B.

[0171] The controller 72B1 displays first images 62L2, 62R2 indicating an object to be operated by the operating tool 62 in an area near the operating tool 62. For example, as shown in Fig. 10A and Fig. 11D (third setting screen Q4), the controller 72B1 displays first images 62L2, 62R2 indicating that the control valve 31 that adjusts the first supply flow rate and the second supply flow rate is an object to be operated in areas 110Fa and 110Ga of the second display screen 61B near the operating tool 62.

[0172] As shown in FIG. 12A , the storage unit 72B3 stores a table T1 that associates operation targets that accept operation inputs from the operation tool 62 for each operation screen with first images 62L1, 62L2, 62R1, and 62R2 that represent the operation targets. For example, the event handler 72B2 refers to the table T1 and switches the operation target that is accepted by the operation tool 62 depending on the application selected and operated by the first operation unit 121. When the worker U1 rotates the operation tool 62, the event handler 72B2 detects the rotation direction and the amount of operation of the operation tool 62. The event handler 72B2 converts the detected amount of operation into an instruction signal according to the table T1 and inputs it to the control unit 70. The control unit 70 performs control according to the input instruction signal.

[0173] Specifically, when the worker U1 operates the app icon 121a (when the first application is selected and operated with the first operation unit 121), the event handler 72B2 refers to the table T1 and changes the operation target accepted by the operation tool 62L to an operation for adjusting the air conditioning airflow rate, and changes the operation target accepted by the operation tool 62R to an operation for adjusting the air conditioning temperature. The event handler 72B2 inputs an instruction signal to the controller 72B1 to display the first setting screen Q2. The controller 72B1 displays the first setting screen Q2 on the second display screen 61B based on the instruction signal from the event handler 72B2 and the table T1. More specifically, the controller 72B1 displays a first image 62L1 indicating the operation for adjusting the air conditioning airflow rate in the area 110F of the second display screen 61B. The controller 72B1 displays a first image 62R1 indicating the operation for adjusting the air conditioning temperature in the area 110G of the second display screen 61B.

[0174] When the worker U1 rotates the operating tool 62L on the first setting screen Q2, the event handler 72B2 detects the rotation direction and the amount of rotation of the operating tool 62L. The event handler 72B2 converts the rotation direction and the amount of rotation detected by the operating tool 62L into an instruction signal for controlling the air volume of the air conditioner 74. The event handler 72B2 inputs the instruction signal for controlling the air volume of the air conditioner 74 to the control unit 70.

[0175] When the worker U1 rotates the operating tool 62R on the first setting screen Q2, the event handler 72B2 detects the rotation direction and the amount of operation of the operating tool 62R. The event handler 72B2 converts the rotation direction and the amount of operation detected by the operating tool 62R into an instruction signal for controlling the temperature of the air conditioner 74. The event handler 72B2 inputs the instruction signal for controlling the temperature of the air conditioner 74 to the control unit 70.

[0176] When the worker U1 operates the application icon 121b (when the second application is selected and operated with the first operation unit 121), the event handler 72B2 refers to the table T1 and changes the operation target accepted by the operation tool 62L to an operation for switching the radio reception frequency, and changes the operation target accepted by the operation tool 62R to an operation for adjusting the volume of sound output from the speaker. The event handler 72B2 inputs an instruction signal to the controller 72B1 to display the second setting screen Q3. The controller 72B1 displays the second setting screen Q3 on the second display screen 61B based on the instruction signal from the event handler 72B2 and the table T1. Specifically, the controller 72B1 displays a first image 62L1 indicating an operation for switching the radio reception frequency in the area 110F of the second display screen 61B. The controller 72B1 displays a first image 62R1 indicating an operation for adjusting the volume of sound output from the speaker in the area 110G of the second display screen 61B.

[0177] The event handler 72B2 may change the operation target accepted by the operation tool 62 in accordance with the operation of the second operation unit 122.

[0178] As shown in FIG. 11D (third setting screen Q4), when the operator U1 operates the function operating member 122c1, which is the second operating unit 122, the event handler 72B2 refers to table T1 and changes the operation accepted by the operating device 62L to an operation to adjust the first supply flow rate, and changes the operation accepted by the operating device 62R to an operation to adjust the second supply flow rate.

[0179] When worker U1 operates the function operating member 122c2, which is the second operating unit 122, the event handler 72B2 refers to table T1 and changes the operation received by operating device 62L to an operation to adjust the third supply flow rate, and changes the operation received by operating device 62R to an operation to adjust the fourth supply flow rate.

[0180] In addition, the controller 72B1 refers to the table T1 in response to the operation of the second operation unit 122 (in response to an instruction signal from the event handler 72B2) and controls the switching of the first images 62L1, 62L2, 62R1, and 62R2 to be displayed on the second display screen 61B.

[0181] In this embodiment, the case where the supply flow rate of hydraulic oil to the first service port 41 and the second service port 42 is adjusted by the operating devices 62L and 62R has been described. However, this is not limited to this, and the supply flow rate to actuators such as the dozer cylinder C1, swing cylinder C2, boom cylinder C3, arm cylinder C4, attachment cylinder C5, swing motor MT, first traveling motor ML, and second traveling motor MR may also be adjustable by the operating devices 62L and 62R.

[0182] Furthermore, when an operation is received on the fourth operation unit 124, the event handler 72B2 and the controller 72B1 may switch between the operation target received by the operating tool 62 and the first image indicating the operation target of the operating tool 62. For example, as shown in FIG. 11A (home screen Q1) and FIG. 9 , when the controller 72B1 is displaying the home screen Q1 on the second display screen 61B, the controller 72B1 displays, on the second display screen 61B, first images 62L1 and 62R1 indicating air conditioning operations of the air conditioner 74. The event handler 72B2 switches the operation target received by the operating tool 62 to operations for the air volume and temperature of the air conditioner 74.

[0183] 5, the second display device 60B has a vibration element 63. The event handler 72B2 controls the vibration of the vibration element 63 in response to an operation input to at least one of the operation unit 120 and the operation tool 62.

[0184] More specifically, when the worker U1 touches the operation unit 120 with his / her fingertip, the event handler 72B2 detects that the operation unit 120 has been operated. The event handler 72B2 inputs an instruction signal for an operation related to the work machine 1 corresponding to the operation unit 120 to the control unit 70, and vibrates the vibration element 63 for a predetermined time. The predetermined time for vibrating the vibration element 63 is, for example, approximately 0.1 seconds, which is a relatively short time.

[0185] The predetermined time for vibrating the vibration element 63 is not limited as long as it is a time that allows the worker U1 to recognize that the operation input on the second display device 60B has been accepted.

[0186] Furthermore, while the worker U1 is pressing and holding the operation unit 120, the event handler 72B2 may continuously vibrate the vibration element 63. Specifically, when the event handler 72B2 detects contact with the operation unit 120, it starts (turns ON) the vibration of the vibration element 63. Furthermore, when the event handler 72B2 no longer detects contact with the operation unit 120, it ends (turns OFF) the vibration of the vibration element 63.

[0187] While the worker U1 is operating the manipulating tool 62, the event handler 72B2 vibrates the vibration element 63. Specifically, when the worker U1 rotates the manipulating tool 62, the event handler 72B2 detects the amount and speed of operation of the manipulating tool 62. The event handler 72B2 inputs an instruction signal for operation related to the work machine 1 corresponding to the manipulating tool 62 to the control unit 70, and vibrates the vibration element 63.

[0188] When an operation input is made to the operation tool 62, the event handler 72B2 changes the vibration mode of the vibration element 63 in response to the operation amount of the operation tool 62, depending on the operation target of the operation tool 62. The storage unit 72B3 stores in advance a plurality of vibration modes with different vibration frequencies, vibration amplitudes, and vibration patterns as vibration modes.

[0189] 12B to 12E are diagrams showing the vibration modes of the vibration element 63. As shown in FIGS. 12B and 12C, vibration modes M1 and M2 have different vibration frequencies. As shown in FIGS. 12B and 12D, vibration modes M1 and M3 have different vibration amplitudes. As shown in FIGS. 12B and 12E, vibration mode M4 vibrates (vibration ON) at substantially the same vibration frequency and vibration amplitude as vibration mode M1 for a predetermined time t1, and stops vibrating (vibration OFF) for a predetermined time t2, and this cycle is repeated periodically. In other words, vibration modes M1 and M4 have different vibration patterns.

[0190] 12A, for example, table T1 stores vibration modes M1 to M4 associated with operation targets of the operation tool 62. When the worker U1 rotates the operation tool 62, the event handler 72B2 references table T1 and acquires the vibration mode corresponding to the operation target (device) selected as the operation target. The event handler 72B2 vibrates the vibration element 63 based on the acquired vibration mode.

[0191] The event handler 72B2 changes the vibration frequency or vibration amplitude of the vibration element 63 in accordance with at least one of the operation speed and the operation amount of the operation tool 62.

[0192] For example, the event handler 72B2 switches the vibration mode in two stages: when the operation speed of the operation tool 62 is less than a predetermined value v1, and when the operation speed is equal to or greater than v1. The event handler 72B2 switches the vibration mode in two stages: when the operation amount of the operation tool 62 is less than a predetermined value n1, and when the operation amount is equal to or greater than n1. Note that the number of stages described above is merely an example and is not limited thereto.

[0193] 12A , table T1 stores the operation speed and operation amount of the manipulating tool 62 in association with the vibration mode. When the worker U1 rotates the manipulating tool 62, the event handler 72B2 detects the operation amount and operation speed of the manipulating tool 62. The event handler 72B2 references table T1, obtains the vibration mode corresponding to the operation target, operation amount, and operation speed of the manipulating tool 62, and vibrates the vibration element 63.

[0194] The event handler 72B2 may continuously change the vibration frequency and / or vibration amplitude of the vibration element 63 in accordance with the operation speed and / or operation amount. For example, the storage unit 72B3 may store, in advance, an arithmetic expression, in which the operation speed and / or operation amount of the manipulating tool 62 is used as a weighting value, in association with Table T1 as one of the vibration modes. When the worker U1 rotates the manipulating tool 62, the event handler 72B2 references Table T1 to obtain the arithmetic expression (vibration mode). The event handler 72B2 calculates the vibration frequency and / or vibration amplitude using the operation speed and / or operation amount and the arithmetic expression. The event handler 72B2 vibrates the vibration element 63 based on the calculated vibration frequency and / or vibration amplitude.

[0195] [Second embodiment] In the above first embodiment, the case where the work machine 1 is provided with the first display device 60A and the second display device 60B has been described, but if the work machine 1 has only the second display device 60B, the second display screen 61B (display screen 61B) may display information related to the work machine 1. Below, the work machine 1 of the second embodiment will be described, focusing on configurations that differ from the above-mentioned embodiment (first embodiment), and configurations that are common to the first embodiment will be assigned the same reference numerals and will not be described in detail.

[0196] 13 is a control block diagram of the second embodiment. The work machine 1 in the second embodiment includes a display device 60B (second display device 60B) having a display screen 61B, and a display control device 72B (controller 72B1, event handler 72B2, storage unit 72B3) that controls the display of the display device 60B.

[0197] The controller 72B1 can transition the display screen 61B from a first display state S1 to a second display state S2. For example, when the controller 72B1 is displaying the home screen Q1, which is the first display state S1, on the display screen 61B ( FIG. 14A ), if the worker U1 operates the application icon 121b of the first operation unit 121, the controller 72B1 transitions the display screen 61B from the first display state S1 to a second setting screen Q3, which is the second display state S2 ( FIG. 14B ).

[0198] The controller 72B1 can transition the display screen 61B from the second display state S2 to the first display state S1. For example, when the controller 72B1 is displaying the second setting screen Q3 in the second display state S2 ( FIG. 14B ), if the worker U1 operates the fourth operation unit 124, the controller 72B1 transitions the display screen 61B from the second display state S2 to the home screen Q1 ( FIG. 14A ), which is the first display state S1.

[0199] As shown in Figures 14A and 10B, in the first display state S1, the controller 72B1 displays the first operation unit 121 in the first display area 110E and displays the status information 90 of the work machine 1 in the second display area 110D.

[0200] In the first display area 110E of the display screen 61B, a plurality of application icons that accept the selection of an application to be operated are arranged side by side. In the second display area 110D, status information 90 that indicates the status of the work machine 1 is arranged. Note that the application icons do not have to be the same size. For example, an application icon that is used relatively frequently may be displayed larger than an application icon that is used relatively less frequently.

[0201] 14C , in the second display state S2, the controller 72B1 displays the first operation unit 121 in the first display region 110E, and displays the second operation unit 122 in the second display region 110D, superimposed on the status information 90 of the work machine 1 in the first display state S1. For example, the controller 72B1 continues to display the status information 90, and displays the second operation unit 122. The controller 72B1 may also display the second operation unit 122, to which a transparency process (making the background transparent) has been applied, in the second display region 110D.

[0202] 14A and 10B, when a warning condition occurs in the work machine 1, the controller 72B1 displays warning information 81 (message image 81a) related to the warning condition in the fourth display area 110H, which is an area above the operating tool 62. The warning information 81 may be positioned so as to overlap the first display area 110E and the second display area 110D. As shown in FIG. 14A, the controller 72B1 displays an icon image 81b indicating the type of abnormality in the second display area 110D.

[0203] The display control device 72B may also arrange, on the display screen 61B, a setting operation unit 105 that accepts input of setting information for the work machine 1 in the first embodiment. The controller 72B1 displays, in the display area 110E, a second switching operation unit 104 that selects the display of the setting operation unit 105 as the first operation unit 121. As shown in FIG. 14D , when the worker U1 operates the second switching operation unit 104, the controller 72B1 displays a setting operation screen Q5 on the display screen 61B. The controller 72B1 displays the setting operation unit 105, into which setting information for the work machine 1 can be input. The event handler 72B2 accepts the setting information. The controller 72B1 displays, in the second display area 110D, the setting operation unit 105 that accepts input of setting information for the work machine 1. Note that the controller 72B1 may continue to display the status information 90 or the second operation unit 122 and display the setting operation unit 105 superimposed thereon.

[0204] Note that first display area 110E and second display area 110D may be included in second upper area 110A separate from the area where operating tool 62 is provided, and the area ratio between first display area 110E and second display area 110D may be different between second display state S2 and first display state S1. As shown in Figures 14A and 14B, first display area 110E in which first operating unit 121 is arranged in second display state S2 is narrower than first display area 110E in first display state S1. Also, second display area 110D in which second operating unit 122 is arranged in second display state S2 is wider than second display area 110D in which status information 90 is arranged in first display state S1.

[0205] When transitioning from the second display state S2 to the first display state S1, the controller 72B1 narrows the second display region 110D in which the status information 90 is arranged and widens the first display region 110E in which the first operation unit 121 is arranged. When transitioning from the first display state S1 to the second display state S2, the controller 72B1 widens the second display region 110D in which the second operation unit 122 is arranged and narrows the first display region 110E in which the first operation unit 121 is arranged.
