[0060] As shown in FIG5 , the CPU 20 operates based on a predetermined program and functionally includes an input receiving unit 31, a mode switching unit 32, a display control unit 33, and a view control unit 34. In addition, the predetermined program may be a program for realizing a part of the function of the display control device 2. For example, the program may be a program that functions by combining with other programs stored in the storage unit 25 or with other programs installed in other devices.

[0061] The input accepting unit 31 accepts operation input from the jog dial 50. When the input accepting unit 31 has received operation input from the operator to the dial 51 of the jog dial 50 and any one of the first button 52 to the fourth button 55, the input accepting unit 31 accepts input of an operation signal corresponding to the content of the operation input output from the jog dial 50.

[0062] The display control section 33 controls information displayed on the guide screen Z according to the operation input that has been performed at the jog dial 50 . The display control section 33 generates a display signal for displaying the guide screen Z on the monitor 22 .

[0063] FIG. 6 is a diagram showing an example of a guide screen displayed in the display area of ​​the monitor according to the embodiment of the present disclosure.

[0064] The storage unit 25 stores information on a plurality of group areas G set on the guide screen Z, and a plurality of icons J11 to J15 , J51 to J55 arranged as item information in each of the plurality of group areas G, and the alarm information J21 .

[0065] As shown in FIG6 , on the display area 22a of the monitor 22, a guide screen Z is displayed based on a signal generated by the display control unit 33. For example, a plurality of group areas G are set on the guide screen Z. The plurality of group areas G are set by dividing the display area 22a into a plurality of groups. In the present embodiment, for example, five group areas G1 to G5 are set on the guide screen Z.

[0068] The group regions G3 and G4 display field of view images V3 and V4 related to the state of the working machine 1. The field of view images V3 and V4 display, for example, the state of the working machine 1.

[0069] As the state of the working machine 1, the operation state of the movable part of the working machine 1 is displayed on the field of view images V3 and V4 displayed in the group areas G3 and G4, for example. For example, a side view, a top view, a front view, and a 3D screen can be displayed as the field of view images V3 and V4. The side view is an image showing the body of the working machine 1 and its surrounding terrain as viewed from the side. The top view is an image showing the state of the body of the working machine 1 and its surrounding terrain as viewed from above. The front view is an image showing the bucket BK of the working machine 1 and its surrounding terrain as viewed by the operator who has sat on the seat ST. The 3D screen is an image that displays the body of the working machine 1 and its surrounding terrain as a three-dimensional image. As the field of view images V3 and V4 displayed in the group area G3, the display control unit 33 displays an image selected from the side view, the top view, the front view, and the 3D screen by operating the jog dial 50. In addition, the viewpoint (line of sight direction) in the field of view images V3 and V4 can be changed by operating the jog dial 50.

[0070] As shown in FIG6 , information indicating the positional relationship between the working machine and the surrounding terrain (design surface) is displayed on the field of view image V4 displayed in the group area G4 as the state of the working machine 1. The position of the working machine 1 is acquired via the GNSS antennas N1 and N2 and the communication interface 24. Here, the information indicating the position of the working machine 1 refers to three-dimensional coordinate information expressed in the world coordinate system.

[0071] The storage unit 25 has previously recorded the designed surface of the terrain data acquired as three-dimensional data. The display control unit 33 displays the surrounding terrain of the working machine 1 in the field of view image V4 based on the terrain data and the positioning information of the working machine 1 based on the GNSS antennas N1 and N2. The surrounding terrain includes information on the construction surface D constructed by the working machine 1. The information on the construction surface D includes coordinate information for specifying the construction surface D and the like.

[0072] The surrounding terrain displayed in the field of view image V4 can be enlarged or reduced by operating the jog dial 50.

When a specific construction surface D is selected by operating the jog dial 50, various information related to the construction surface D can also be displayed.

[0073] A plurality of icons J51 to J55 as item information are arranged in the group area G5. A prescribed function is assigned to each of the plurality of icons J51 to J55. The plurality of icons J51 to J55 can be selected by operating the jog dial 50. For each of the plurality of icons J51 to J55, when it is selected by operating the jog dial 50, the prescribed function assigned in advance is expressed.

[0074] FIG. 7 is a diagram schematically showing transition of operation modes in the display control device according to the embodiment of the present disclosure.

[0075] The mode switching unit 32 switches the operation mode on the guide screen Z displayed in the display area 22a based on the operation input from the jog dial 50 accepted by the input acceptance unit 31. As shown in FIG7 , the mode switching unit 32 alternately switches between the focus operation mode M1 and the mouse operation mode M2 ​​based on the operation input from the jog dial 50. In the present embodiment, for example, the switching between the focus operation mode M1 and the mouse operation mode M2 ​​is performed by pressing the fourth button 55.

[0076] (Explanation of Focus Operation Mode)

[0077] FIG. 8 is a diagram schematically showing transition of a selection state of a group area in the display control device according to the embodiment of the present disclosure.

[0078] In the focus operation mode M1, the state is first transferred to the group area selection state M11. In the group area selection state M11, one of the plurality of group areas G1 to G5 can be selected. In the group area selection state M11, the plurality of group areas G1 to G5 displayed on the guide screen Z are sequentially selected by the operation of the jog dial 50. In the present embodiment, the group areas G1 to G5 are sequentially selected by the rotation operation of the dial 51. As shown in FIG. 8 , for example, if the dial 51 is rotated clockwise to the right, the group areas G1 to G5 are selected in the order of the group areas G1→G2→G3→G4→G5. In addition, if the dial 51 is rotated counterclockwise to the left, the group areas G1 to G5 are selected in the order of the group areas G5→G4→G3→G2→G1. In order to focus on the group area among the group areas G1 to G5 selected by the operation of the dial 51, the display control unit 33 displays the highlighted display, for example, by displaying the selection frame W1. In addition, emphasis display can also be performed by changing the display color, changing the display brightness, etc.

[0079] In the group area selection mode M11 , when any one of the group areas G1 to G5 is selected, for example, when the dial 51 is pressed, the mode switching unit 32 shifts to the item information selection state M12 or the field of view operation state M13 .

[0080] FIG. 9 is a diagram schematically showing transitions of selection states of a plurality of icons in the display control device according to the embodiment of the present disclosure.

[0081] In the focus operation mode, when any one of the group areas G1 , G2 , and G5 is selected and the dial 51 is pressed, the state shifts to the item information selection state M12 .

[0082] In the item information selection state M12, for example, when the group area G1 is selected, one of the icons J11 to J15 arranged in the selected group area G1 becomes selectable. As shown in FIG9 , in the item information selection state M12, the icons J11 to J15 are sequentially selected by the operation of the jog dial 50. In the present embodiment, the icons J11 to J15 are sequentially selected by the rotation operation of the dial 51. For example, if the dial 51 is rotated clockwise to the right, the icons J11 to J15 are selected in the order of icons J11→J12→J13→J14→J15. In addition, if the dial 51 is rotated counterclockwise to the left, the icons J11 to J15 are selected in the order of icons J15→J14→J13→J12→J11. In order to focus on the icon among the icons J11 to J15 selected by the operation of the dial 51, for example, the display control unit 33 displays the highlighted display by displaying the selection frame W2. In addition, emphasis display can also be performed by changing the display color, changing the display brightness, etc.

[0083] In the item information selection state M12 , in a state where any one of the icons J11 to J15 is selected, for example, when the dial 51 is pressed, the CPU 20 executes a desired function to which the selected icon J11 to J15 is assigned.

[0084] In the item information selection state M12 , for example, when the group area G2 is selected, the display transitions to the detailed information of the alarm information J21 by, for example, pressing the dial 51 .

[0085] In the item information selection state M12 , for example, when the group area G5 is selected, similarly to the group area G1 , the dial 51 is rotated and pressed in sequence to select any one of the icons J51 to J55 , and the CPU 20 executes a desired function.

[0086] In addition, in the item information selection state M12 , for example, when the first button 52 is pressed, the state returns to the group area selection state M11 .

[0087] In the focus operation mode M1 , when the group areas G3 and G4 are selected and the dial 51 is pressed, the state shifts to the field of view operation state M13 .

[0088] In the field of view operation state M13, for example, when the group area G3 is selected, the field of view control unit 34 moves the field of view image V3 displayed in the selected group area G3 to an effective state. The effective state refers to a state in which the field of view image V3 can be operated based on the jog dial 50. For example, when the dial 51 is tilted forward, the field of view control unit 34 moves the viewpoint of the field of view image V3 upward. In addition, when the dial 51 is tilted backward, the field of view control unit 34 moves the viewpoint of the field of view image V3 downward. When the dial 51 is tilted to the left, the field of view control unit 34 moves the viewpoint of the field of view image V3 to the left. When the dial 51 is tilted to the right, the field of view control unit 34 moves the viewpoint of the field of view image V3 to the right.

[0089] Furthermore, for example, when the dial 51 is rotated clockwise, the field of view control unit 34 enlarges the field of view image V3 , and when the dial 51 is rotated counterclockwise, the field of view control unit 34 reduces the field of view image V3 .

[0090] Furthermore, for example, by pressing the first button 52 and the second button 53 , the field of view image V3 can be switched in sequence between the side view, the top view, the front view, and the 3D image.

[0091] In the field of view operation state M13 , for example, when the group area G4 is selected, the field of view control unit 34 shifts the field of view image V4 displayed in the selected group area G4 to the effective state. The effective state is a state in which the field of view image V4 can be operated using the jog dial 50 .

[0092] FIG. 10 is a diagram schematically showing transition of a display state of a field of view image in a display control device according to an embodiment of the present disclosure.

[0093] As shown in FIG. 10 , in the field of view operation state M13, the reference mark K is displayed at a specified position of the field of view image V4. For example, when the dial 51 is tilted forward, the field of view control unit 34 moves the area of ​​the surrounding terrain displayed in the field of view image V4 upward with the reference mark K as the center. In addition, when the dial 51 is tilted backward, the field of view control unit 34 moves the area of ​​the surrounding terrain displayed in the field of view image V4 downward with the reference mark K as the center. When the dial 51 is tilted to the left, the field of view control unit 34 moves the area of ​​the surrounding terrain displayed in the field of view image V4 to the left with the reference mark K as the center. When the dial 51 is tilted to the right, the field of view control unit 34 moves the area of ​​the surrounding terrain displayed in the field of view image V4 to the right with the reference mark K as the center.

[0094] In addition, by appropriately tilting the dial 51, the display area of ​​the surrounding terrain is adjusted with the reference mark K as a reference. When the reference mark K is overlapped on the construction surface D, if the operation dial 51 is pressed, the field of view control unit 34 can display various information related to the construction surface D.

[0095] Furthermore, for example, when the dial 51 is rotated clockwise, the field of view control unit 34 enlarges the field of view image V4, and when the dial 51 is rotated counterclockwise, the field of view control unit 34 reduces the field of view image V4.

[0096] In addition, in the field of view operation state M13 , for example, when the first button 52 is pressed, the state returns to the group area selection state M11 .

[0097] (Description of Mouse Operation Mode)

[0098] FIG. 11 is a diagram schematically showing a mouse operation pattern in the display control device according to the embodiment of the present disclosure.

[0099] As shown in FIG. 11 , in the mouse operation mode M2, the display control unit 33 displays a mouse cursor P on the guide screen Z displayed on the display area 22 a. In the mouse operation mode M2, the display control unit 33 moves the position of the mouse cursor P on the guide screen Z according to the operation based on the jog dial 50. For example, when the dial 51 is tilted forward, the display control unit 33 moves the mouse cursor P upward on the guide screen Z. When the dial 51 is tilted backward, the display control unit 33 moves the mouse cursor P downward. When the dial 51 is tilted to the left, the display control unit 33 moves the mouse cursor P to the left. When the dial 51 is tilted to the right, the display control unit 33 moves the mouse cursor P to the right.
