Abstract

A display system of an excavating machine that includes a work machine having a bucket, and a main body to which the work machine is attached, the display system includes: a storage unit configured to store at least position information of a design surface; a display unit configured to display the position information of the design surface on a screen; and a processing unit configured to display an outer edge of a second plane of the design surface, the second plane including a first plane existing in the design surface, the second plane existing in a part of a periphery of the first plane, on the screen of the display unit, in a different form from inside and outside of the outer edge.

Claims

1. A display system of an excavating machine that includes a work machine having a bucket, and a main body to which the work machine is attached, and that is configured to perform construction according to a design surface, the display system comprising:

a storage unit configured to store at least position information of the design surface;

a display unit configured to display the position information of the design surface on a screen; and

a processing unit configured to display an outer edge of a second plane of the design surface, the second plane including a first plane existing in the design surface, the second plane existing in a part of a periphery of the first plane, on the screen of the display unit, in different forms as between the inside and the outside of the outer edges.

2. The display system of an excavating machine according to claim 1, wherein

the design surface is divided by a plurality of surface elements,

the first plane is one of the plurality of surface elements, and

the second plane is at least one of the plurality of surface elements, the one existing in the periphery of the first plane, and is able to be considered to exist in a same plane as the surface element corresponding to the first plane.

3. The display system of an excavating machine according to claim 1, wherein

the processing unit displays the position information of the design surface, the outer edge, and a pattern corresponding to the excavating machine, on a same screen of the display unit.

4. The display system of an excavating machine according to claim 1, wherein

the processing unit displays a plurality of the different first planes, and the outer edges of the second planes corresponding to the respective first planes, on a same screen of the display unit, in different forms from the inside and outside of the outer edges.

5. The display system of an excavating machine according to claim 1, wherein

the processing unit displays light and shade that occurs when the design surface is irradiated with light from a predetermined direction, on the screen of the display unit, together with the design surface.

6. The display system of an excavating machine according to claim 5, wherein

the processing unit irradiates the design surface with the light from a position of a light attached to the excavating machine.

7. The display system of an excavating machine according to claim 1, comprising:

a display switching unit configured to transmit a display switching command for displaying the inside of the outer edge in a different form from the outside of the outer edge, wherein

when the processing unit receives the display switching command from the display switching unit, the processing unit displays the inside of the outer edge, on the screen of the display unit, in a different form from the outside of the outer edge.

8. The display system of an excavating machine according to claim 1, wherein

the processing unit displays at least the outer edge of the second plane existing directly below the bucket, on the screen of the display unit, in a different form from the inside and the outside of the outer edge.

10. An excavating machine comprising:

a display system of the excavating machine according to claim 1.

9. A display system of an excavating machine that includes a work machine having a bucket, and a main body to which the work machine is attached, and that is configured to perform construction according to a design surface, the display system comprising:

a storage unit configured to store at least position information of the design surface divided by a plurality of surface elements;

a display unit configured to display the position information of the design surface on a screen;

a vehicle state detection unit configured to detect at least information related to a current position of the excavating machine; and

a processing unit configured to display an outer edge of a second plane of the design surface, the second plane including a first plane existing in the design surface, the second plane existing in a part of a periphery of the first plane, on the screen of the display unit, in different forms as between the inside and the outside of the outer edges, and further to display a pattern corresponding to the excavating machine, on the same screen as the outer edge of the second plane, wherein

the second plane exists in a range surrounded by two planes existing in positions away from the first plane by a predetermined distance, in a direction perpendicular to the first plane.
