Excavating machine display system and excavating machine

摘要

The display system of the excavating machine has a work machine condition detection unit which detects information related to a current position of an excavating machine and a processing unit. This processing unit calculates an icon display of the bucket and the positions of the excavation edge portions viewed from a top of the excavating machine based on the information related to the current position of the excavating machine, the information related to the posture of the main body, the information about the positions of the excavation edge portions and the outer shape information about the bucket, and displays on a screen of a display device the target surface, the icon display position of the bucket, and an image which indicates the positions of the excavation edge portions.

主权项

1. A display system of an excavating machine, the excavating machine comprising a work machine which includes a bucket including an excavation edge portion and a main body which is attached to the work machine, the excavating machine display system comprising:
a work machine condition detection unit which detects information related to a current position of the excavating machine, information related to a posture of the main body and information about a position of the excavation edge portion; a memory unit which stores position information about a target surface which indicates a design geography and outer shape information about the bucket; and a processing unit which calculates positions of the bucket and the excavation edge portion viewed from a top face of the excavating machine based on the information related to the current position of the excavating machine, the information related to the posture of the main body, the information about the position of the excavation edge portion and the outer shape information about the bucket, and displays on a screen of a display device the target surface, an image which indicates the bucket and an image which indicates the position of the excavation edge portion, wherein even when the excavation edge portion comes to a position at which the excavation edge portion cannot be originally viewed from a top due to an outer shape of the bucket, the processing unit displays at all times the image which indicates the position of the excavation edge portion preferentially over the image which indicates the bucket, on the screen which displays the excavating machine from the top face of the excavating machine such that a relative position of the excavation edge portion with respect to the image which indicates the bucket viewed from the top face is intelligible.
