Abstract

A display controller for controlling a content displayed on the display provided on the working machine comprises a display control unit. The display control unit is configured to display, on the display, an icon image indicating information regarding the working machine and a plurality of graphic meter images indicating respective conditions of the working machine so that the graphic meter images, each in an arcuate shape, are displayed as being arranged so as to surround the icon image.

First claim

What is claimed is:

1. A display controller for controlling content displayed on a display provided on a working machine, the display controller comprising:
a display control unit configured to display, in a first display region of the display, selectively either a plurality of arcuate graphic meter images indicating conditions of the working machine in a first display state or a photographed image of surroundings of the working machine in a second display state,
wherein the display control unit is configured so that, in the first display state, an icon image is displayed at a central portion of the first display region, and the graphic meter images are displayed in the first display region around the icon image, and
wherein the display control unit is configured so that, in the second display state, the icon image is displayed in a second display region of the display smaller than the first display region, and bar images indicating the same information as the graphic meter images are displayed in the second display region on both sides of the icon image.

2. The display controller according to claim 1 ,
wherein the display control unit is configured so that, when a predetermined menu displaying operation is performed, a menu image indicating a plurality of optional items is displayed in a partial section of a display screen of the display.

3. The display controller according to claim 1 ,
wherein the display control unit is configured to display, in the first display region of a display screen, either the plurality of graphic meter images or the photographed image of surroundings of the working machine,
wherein the display control unit is configured so that, when a predetermined warning condition of the working machine occurs, a piece of warning information corresponding to the occurring warning condition is indicated in the second display region which is smaller than the first display region, and
wherein the display control unit is configured so that, when a plurality of warning conditions occurs, a piece of warning information corresponding to one of the warning conditions is indicated in the second display region, and the number of the pieces of warning information corresponding to the occurring warning conditions is indicated on the display screen.

4. The display controller according to claim 1 ,
wherein the display controller is configured to indicate, on the display, maximum flow rate levels of hydraulic fluid supplied or discharged to or from an actuator for driving an attachment,
wherein the display controller comprises a storage unit storing plural kinds of attachments capable of being attached to the working machine and settings of the maximum flow rate levels corresponding to the respective kinds of attachments, and
wherein the display control unit is configured to indicate, on the display, a list of the settings of the maximum flow rate levels corresponding to the respective kinds of attachments.

5. The display controller according to claim 1 ,
wherein the display controller is configured to display, on the display, flow rate setting images for variable setting of maximum flow rate levels of hydraulic fluid supplied or discharged to or from an actuator for driving an attachment attached to the working machine including operation members each operable in operation directions,
wherein the display controller comprises a storage unit that stores plural kinds of attachments capable of being attached to the working machine, at least one of the operation members required to operate each of the stored kinds of attachments, and at least one of the operation directions for operation of the required at least one operation member to operate each of the stored kinds of attachments,
wherein the display control unit is configured to display, on the display, when an operation to set the maximum flow rate levels of hydraulic fluid corresponding to one attachment selected from the stored kinds of attachments is performed, flow rate setting images which correspond to the respective operation members and correspond to the respective operation directions of each of the operation members,
wherein any of the flow rate setting images, which corresponds to the at least one operation member required to operate the selected kind of attachment and corresponds to the at least one operation direction of the required at least one operation member required to operate the selected kind of attachment, is displayed as being in an active state indicating that the variable setting of the corresponding maximum flow rate level is acceptable, and
wherein any of the flow rate setting images, which corresponds to the at least one operation member unrequired to operate the selected kind of attachment or corresponds to the at least one operation direction unrequired to operate the selected kind of attachment, is displayed as being in an inactive state indicating that the variable setting of the corresponding maximum flow rate level is inacceptable, or is not displayed.

6. A working machine comprising:
the display controller according to claim 1 ; and
a display displaying content that is controlled by the display controller.

7. A computer readable storage medium, which stores a program to be executed by a computer for a processing by means of the display control unit in the display controller according to claim 1 .

8. A display controller for controlling content displayed on a display provided on a working machine, the display controller comprising:
a display control unit configured to display, in a first display region of en the display, selectively either an icon image indicating information regarding the working machine and a plurality of graphic meter images indicating conditions of the working machine in a first display state or a photographed image of surroundings of the working machine in a second display state,
wherein, in the first display state, the display control unit is configured to display the graphic meter images, each in an arcuate shape, arranged to collectively form an outline of a common phantom circle so that each of the graphic meter images defines a part of the phantom circle and that the icon image is located within the phantom circle and surrounded by the graphic meter images,
wherein, in the second display state, the display control unit is configured to display, in a second display region of the display, the icon images and bar images indicating the same information as the graphic meter images.

9. The display controller according to claim 8 ,
wherein the display control unit is configured to display the graphic meter images each in an arcuate shape such that the phantom circle has a center thereof at a central portion of the icon image.

10. The display controller according to claim 8 ,
wherein the display control unit is configured to display the graphic meter images including a first graphic meter image arranged below the icon image, a second graphic meter image arranged rightward from the icon image, and a third graphic meter image arranged leftward from the icon image.

11. The display controller according to claim 8 ,
wherein the icon image indicates an attachment attached to the working machine.

12. The display controller according to claim 8 ,
wherein the display control unit is configured to display the graphic meter images including some or all of graphic meter images indicating a residual quantity of fuel for driving an engine equipped on the working machine, a temperature of engine oil or engine cooling water for the engine, and a temperature of hydraulic fluid for driving an attachment attached to the working machine.
