EXCAVATION CONTROL SYSTEM FOR HYDRAULIC EXCAVATOR

摘要

An excavation control system includes a working unit having a bucket, a designed landform data storage part storing designed landform data, a bucket position data generation part that generates bucket position data, a designed surface data generation part, and an excavation limit control part. The designed surface data generation part generates superior and subordinate designed surface data based on the designed landform and bucket position data. The superior designed surface data indicates a superior designed surface corresponding to a position of the bucket. The subordinate designed surface data indicates a first subordinate designed surface linked to the superior designed surface. The designed surface data generation part generates shape data indicating shapes of the superior designed surface and the first subordinate designed surface. The excavation limit control part automatically adjusts a position of the bucket.

主权项

1. An excavation control system for a hydraulic excavator, the excavation control system comprising:
a vehicle main body, a working unit having a boom, an arm and a bucket, the boom being attached to the vehicle main body, the arm being attached to the boom, the bucket being attached to the arm; a designed landform data storage part configured to store designed landform data indicating a target shape of an excavation object; a bucket position data generation part configured to generate bucket position data indicating a current position of the bucket; a designed surface data generation part configured to generate superior designed surface data and subordinate designed surface data based on the designed landform data and the bucket position data, the superior designed surface data indicating a superior designed surface corresponding to a position of the bucket, the subordinate designed surface data indicating a first subordinate designed surface linked to the superior designed surface, the designed surface data generation part being configured to generate shape data indicating shapes of the superior designed surface and the first subordinate designed surface; and an excavation limit control part configured to automatically adjust a position of the bucket in relation to the superior designed surface and the first subordinate designed surface based on the shape data and the bucket position data.
