Abstract

This display control system includes a display processing unit that causes a display device to display a display screen. The display screen includes a remaining-amount display region and a switching display region. The remaining-amount display region is a region for displaying remaining-amount information, which concerns the remaining amount of an object to be monitored that is consumed with the operation of a work machine. The switching display region is a region for displaying information to be displayed which is switchably selected from among a plurality of pieces of information including at least first piece of information and second piece of information which are related to the work machine. The switching display region is arranged in a central area including the center of a display screen. The remaining-amount display region is arranged in a peripheral area located at the periphery of the central area of the display screen.

First claim

The invention claimed is:

1 . A work machine display control system comprising:
a display processing portion that makes a display device display a display screen including:
a remaining-amount display region that displays remaining-amount information about a remaining amount of an observation target that is consumed when a work machine is activated; and
a switching display region that displays display target information selected from a plurality of pieces of information including at least a first information comprising an actuation state of the work machine and a second information about the work machine so that displayed information can be switched between the plurality of pieces of information; wherein:
the switching display region is disposed on a central area including a center of the display screen,
the second information comprises a periphery image of an area around the work machine and wherein the periphery image is not overlaid with the remaining-amount information, and
the remaining-amount display region is disposed on a peripheral area that is positioned on a periphery of the central area of the display screen, wherein:
the display processing portion is further configured to switch the display target information that is displayed in the switching display region according to a state of a cutoff lever that prohibits operation of the work machine, so that, when the cutoff lever operates to release prohibition of operation of the work machine, the second information is displayed as the display target information.

2 . The work machine display control system according to claim 1 , wherein the display processing portion displays providing information about the first information on the display screen in a situation in which at least the first information is not displayed on the switching display region.

3 . The work machine display control system according to claim 2 , wherein the display processing portion displays the providing information on a position other than the switching display region on the display screen.

4 . The work machine display control system according to claim 3 , wherein the display processing portion displays the providing information on a position below the remaining-amount display region on the display screen.

5 . The work machine display control system according to claim 2 , wherein the providing information includes a pictogram about the first information.

6 . The work machine display control system according to claim 1 , wherein the first information is information about an actuation state of the work machine.

7 . The work machine display control system according to claim 6 , wherein the first information is information that indicates a value about the actuation state.

8 . The work machine display control system according to claim 1 , wherein the display processing portion:
has a plurality of display modes including a first mode and a second mode; disposes the switching display region on the central area and disposes the remaining-amount display region on the peripheral area in the first mode and does not display the remaining-amount display region and displays the switching display region so that the switching display region ranges from the central area to the peripheral area in the second mode.

9 . A work machine display system comprising:
the work machine display control system according to claim 1 ; and the display device that displays the display screen.

10 . A work machine comprising:
the work machine display system according to claim 9 ; and a machine body to which the display device is mounted.

11 . A work machine display control method including making a display device display a display screen including:
a remaining-amount display region that is disposed on a peripheral area that is positioned on a periphery of a central area including a center of the display screen and displays remaining-amount information about a remaining amount of an observation target that is consumed when a work machine is activated; a switching display region that is disposed on the central area of the display screen and displays display target information selected from a plurality of pieces of information including at least a first information comprising an actuation state of the work machine and a second information about the work machine so that displayed information can be switched between the plurality of pieces of information, wherein the second information comprises a periphery image of an area around the work machine and wherein the periphery image is not overlaid with the remaining-amount information, wherein the display processing portion is further configured to switch the display target information that is displayed in the switching display region according to a state of a cutoff lever that prohibits operation of the work machine, so that, when the cutoff lever operates to release prohibition of operation of the work machine, the second information is displayed as the display target information.

12 . A work machine display control program that makes one or more processors conduct making a display device display a display screen including:
a remaining-amount display region that is disposed on a peripheral area that is positioned on a periphery of a central area including a center of the display screen and displays remaining-amount information about a remaining amount of an observation target that is consumed when a work machine is activated; a switching display region that is disposed on the central area of the display screen and displays display target information selected from a plurality of pieces of information including at least a first information comprising an actuation state of the work machine and a second information about the work machine so that displayed information can be switched between the plurality of pieces of information, wherein the second information comprises a periphery image of an area around the work machine and wherein the periphery image is not overlaid with the remaining-amount information, wherein the display processing portion is further configured to switch the display target information that is displayed in the switching display region according to a state of a cutoff lever that prohibits operation of the work machine, so that, when the cutoff lever operates to release prohibition of operation of the work machine, the second information is displayed as the display target information.
