Abstract

A display system for an excavator includes: a vehicle state detection unit that detects information related to a current position and attitude of a hydraulic excavator as the excavator; a storage unit that stores at least position information of a target surface representing a target shape of a work object; a bucket inclination detection unit that detects the inclination angle of the bucket; a processing unit that uses the position of the blade edge of the bucket obtained based on the inclination angle of the bucket and information related to the current position and posture of the hydraulic excavator, The angle formed by the cutting edge and the target surface is obtained as the cutting edge inclination angle, and posture information representing information on the posture of the bucket is displayed on the screen of the display unit based on the obtained cutting edge inclination angle.

Description

technical field [0001] The present invention relates to a display system of an excavator, an excavator equipped with the display system, and a computer program for display of the excavator used in the display system of the excavator. Background technique [0002] Generally, in a hydraulic excavator, an operator operates a control lever to drive a working machine including a bucket. At this time, when excavating an inclined surface with a predetermined slope or a groove with a predetermined depth, it is difficult for the operator to judge whether the excavation is performed accurately according to the target shape only by visually observing the operation of the working machine. In addition, the operator needs to be skilled in order to efficiently and accurately excavate the above-mentioned inclined surface with a predetermined inclination according to the target shape. Therefore, for example, there is a technique for assisting an operator by displaying positional information...
