Abstract

The work machine control method includes displaying a display screen including information related to a work machine, on a display device, and switching, when a switching operation unit is operated, the display screen to be displayed on the display device, among a plurality of screens according to a switching pattern. Here, the control method further comprises changing the switching pattern according to a movement state of the work machine.

First claim

The invention claimed is:

1 . A work machine control method comprising:
displaying a display screen including information related to a work machine, on a display device; switching, when a switching operation unit is operated, the display screen to be displayed on the display device, among a plurality of screens according to a switching pattern; and changing the switching pattern according to a movement state based, at least in part, on an operation state of a cutoff lever of the work machine, wherein
when the movement state is a disabled state, the switching operation unit initiates a display of a captured image of the monitoring area around the work machine on the display screen, and
when the movement state is an enabled state, the display of the captured image of the monitoring area around the work machine on the display screen is maintained without regard to further operation of the switching operation unit.

2 . The work machine control method according to claim 1 , wherein
the changing the switching pattern includes changing the number of the plurality of screens to be switched.

3 . The work machine control method according to claim 1 , wherein
the changing the switching pattern includes changing the screen that is a switching destination.

4 . The work machine control method according to claim 1 , wherein
when the movement state is in a first the disabled state, the plurality of screens to be switched include a single or a plurality of camera screens which each include a captured image of a monitoring area around the work machine and a basic screen which does not include the captured image.

5 . The work machine control method according to claim 4 , wherein
the plurality of camera screens differ from each other in a display mode of the captured image.

6 . The work machine control method according to claim 4 , wherein
the plurality of camera screens include a first camera screen that includes, in addition to the captured image, operating information on an operating state of the work machine, and a second camera screen that does not include the operating information.

7 . The work machine control method according to claim 4 , wherein
in the disabled mode, the display mode of the captured image is further changeable by a specific operation of the switching operation unit.

8 . The work machine control method according to claim 1 , wherein
when the movement state is in the enabled state, the plurality of screens to be switched include a plurality of camera screens which each include a captured image of a monitoring area around the work machine.

9 . The work machine control method according to claim 1 , wherein
the switching operation unit is a single operation switch.

10 . The work machine control method according to claim 1 , wherein
the information related to the work machine includes at least one of a remaining amount of fuel, a cooling water temperature, and a hydraulic oil temperature.

11 . The work machine control method according to claim 1 , wherein
the movement state is based further on whether a movement mode of the work machine is a crane mode.

12 . A work machine control system comprising:
a display processor that displays a display screen including information related to a work machine, on a display device; and a switching processor that switches, when a switching operation unit is operated, the display screen to be displayed on the display device, among a plurality of screens according to a switching pattern, wherein the switching processor changes the switching pattern according to a movement state of the work machine.

13 . A work machine comprising:
the work machine control system according to claim 12 ; and a machine body on which the display device is installed.
