Abstract

An information display device includes a display device that is mounted in a construction machine and displays various types of information of the construction machine, and a control device that deletes a display of a guide mark guiding a function of a display change-over switch for changing information displayed on the display device in a screen on which at least information of a fuel amount and information of an engine water temperature are displayed when the construction machine is in the operation state.

Claims

1. An information display device of a construction machine, comprising:

a display device that is mounted in a construction machine and displays various types of information of the construction machine; and

a control device that deletes a display of a guide mark guiding a function of a display change-over switch for changing information displayed on the display device in a screen on which at least information of a fuel amount and information of an engine water temperature are displayed when the construction machine is in an operation state.

2. The information display device of the construction machine according to claim 1,

wherein, when the display of the guide mark is deleted, an input to the display change-over switch is not received.

3. The information display device of the construction machine according to claim 1,

wherein the control device causes information necessary when the construction machine is in the operation state to be displayed at a position of the deleted guide mark.

4. The information display device of the construction machine according to claim 2,

wherein information displayed at the position of the guide mark deleted by the control device is information allocated to a mark in which a plurality of types of information are changed by the display change-over switch to be displayed.

5. The information display device of the construction machine according to claim 1,

wherein, when an error occurs in the construction machine while the construction machine is being operated, the control device displays the guide mark representing the display change-over switch for switching to a screen displaying information of the error.

6. The information display device of the construction machine claim 1,

wherein, when the construction machine is not in the operation state, the control device causes the guide mark to be displayed on the display device.

7. The information display device of the construction machine according to claim 1,

wherein, when there is an input to an operating lever for operating the construction machine, the control device deletes the display of the guide mark.

8. The information display device of the construction machine according to claim 7,

wherein, when a state in which the operating lever is at a neutral position is maintained during a predetermined period of time or less, the control device deletes the display of the guide mark.

9. An information display device of a construction machine, comprising:

a display device that is mounted in a construction machine and displays various types of information of the construction machine;

a display change-over switch that changes information displayed on the display device; and

a control device,

wherein when the construction machine is in an operation state, the control device deletes a display of a guide mark which is displayed on an end portion of a screen of the display device and guides a function of the display change-over switch in a screen on which at least information of a fuel amount and information of an engine water temperature are displayed and causes information necessary when the construction machine is in the operation state to be displayed at a position of the deleted guide mark, and when the construction machine is not in the operation state, the control device causes the guide mark to be displayed on the display device, and when an error occurs in the construction machine while the construction machine is being operated, the control device displays the guide mark representing the display change-over switch for switching to a screen displaying information of the error, and,

wherein, when the display of the guide mark is deleted, an input to the display change-over switch is not received.

10. An information display method of a construction machine, comprising:

determining whether or not a construction machine is in an operation state; and

deleting a display of a guide mark guiding a function of a display change-over switch for changing information displayed on a display device in a screen of the display device on which at least information of a fuel amount and information of an engine water temperature are displayed when the construction machine is in the operation state.

11. The information display method of the construction machine according to claim 10,

wherein the display of the guide mark is deleted, an input to the display change-over switch is not received.

12. The information display method of the construction machine according to claim 10,

wherein, when the construction machine is not in the operation state, the guide mark is displayed on the display device.

13. The information display method of the construction machine according to claim 10,

wherein, when there is an input to an operating lever for operating the construction machine, the display of the guide mark is deleted.

14. The information display method of the construction machine according to claim 13,

wherein, when a state in which the operating lever is at a neutral position is maintained during a predetermined period of time or less, the display of the guide mark is deleted.

15. (canceled)

16. A computer program product having a non-transitory computer readable medium including programmed instructions, wherein the instructions, when executed by a computer, cause the computer to perform:

determining whether or not a construction machine is in an operation state; and

deleting a display of a guide mark guiding a function of a display change-over switch for changing information displayed on a display device in a screen of the display device on which at least information of a fuel amount and information of an engine water temperature are displayed when the construction machine is in the operation state.
