Title:
DEVICE AND METHOD FOR COMPUTING BASIC INFORMATION FOR EXCAVATION REGION RESTRICTION CONTROL, AND CONSTRUCTION MACHINE
Document Type and Number:
Japanese Patent JP2015055109
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a device and method for computing basic information about excavation region restriction control, which can improve efficiency in excavation region restriction control, and to provide a construction machine.SOLUTION: A basic information computing device 30 for computing basic information about region restriction excavation control for controlling a work machine 20 of a construction machine so as not to perform excavation beyond an excavation target surface comprises: a target surface storage device 33 for storing three-dimensional position information of the excavation target surface; a two-dimensional information extraction device 34 for determining an intersection between an excavation target surface or a reference surface based on the same and an operation plane of the work machine 20 on the basis of the three-dimensional position information of the excavation target surface and the present position information of the construction machine and extracting the intersection or a reference line L based on the same as two-dimensional information on the reference surface on the operation plane; and a feature point information transmission device 35 for transmitting the z-coordinate of each of a plurality of feature points P1,P2,... Pn on the reference line L as basic information to a region restriction excavation control device 40.
