Title:
EXCAVATION CONTROL SYSTEM FOR HYDRAULIC SHOVEL
Document Type and Number:
Japanese Patent JP2015007370
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide the excavation control system of a hydraulic shovel capable of acquiring a designed land form corresponding to the current position of a work machine.SOLUTION: An excavation control system includes: a global coordinate arithmetic unit 23; a prediction and correction part 261; a bucket cutting edge position data generation part 282; and a designed land form data generation part 283. The global coordinate arithmetic unit 23 generates turning body azimuth data Q indicating an azimuth that a turning body is facing. The prediction and correction part 261 predicts and corrects the turning body azimuth data Q on the basis of a turning angular speed data Dω indicating the turning angular speed of the turning body and a delay time to generate corrected turning body azimuth data R. The bucket cutting edge position data generation part 282 generates bucket cutting edge position data S indicating the position of a bucket cutting edge on the basis of reference position data and the turning body azimuth data Q and the corrected turning body azimuth data R. The designed land form data generation part 282 generates designed land form data U on the basis of the bucket cutting edge position data S and solid designed land form data T.
