DISPLAY SYSTEM FOR EXCAVATING MACHINE, EXCAVATING MACHINE, AND DISPLAY METHOD FOR EXCAVATING MACHINE

摘要

An excavating machine obtains first and second target swing information indicating an amount of rotation of the work implement, based on a direction of a tooth edge of the bucket, a direction orthogonal to the target plane, and a direction of a swing central axis, and selects the first or second target swing information, based on the obtained first and second target swing information and a first angle and a second angle, and displays the selected target swing information, the amount of rotation being required for the tooth edge to face the target plane, the first angle being a minimum value and the second angle being a maximum value among angles formed by an axis orthogonal to the swing central axis and parallel to an operating plane of the work implement, and imaginary lines passing through the swing central axis and ends of the target plane.

1. A display system for an excavating machine, the display system being used for an excavating machine that can allow an upper swing body including a work implement having a bucket to swing about a predetermined swing central axis, the display system comprising:
a vehicle state detecting unit that detects information about a current position and posture of the excavating machine; a storage unit that stores at least position information of a target plane indicating a target shape of a work object; and a processing unit that obtains first target swing information and second target swing information indicating an amount of swing of the upper swing body including the work implement, based on information including a direction of a tooth edge of the bucket, information including a direction orthogonal to the target plane, and information including a direction of the swing central axis, the amount of swing being required for the tooth edge of the bucket to face the target plane, and the direction of the tooth edge of the bucket being determined based on the information about the current position and posture of the excavating machine, and selects the first target swing information or the second target swing information, based on the obtained first target swing information and second target swing information and a first angle and a second angle, and displays an image corresponding to the selected target swing information on a screen of a display apparatus, the first angle being a minimum value and the second angle being a maximum value among angles formed by an axis orthogonal to the swing central axis and parallel to an operating plane of the work implement, and imaginary lines passing through the swing central axis and ends of the target plane.
