Title:
The arithmetic unit and construction machinery of basic intelligence of digging field restriction control
Document Type and Number:
Japanese Patent JP5952244
Kind Code:
B2
Abstract:
The invention provides a basic information calculator 30 for calculating basic information for area limiting excavation control to control a work device 20 of a construction machinery so that the construction machinery does not perform excavation beyond a target excavation surface. The basic information calculator 30 comprises: a storage device 33 having stored therein the three-dimensional information of the target excavation surface; a two-dimensional information extractor 34 for obtaining the intersecting line between a reference surface that is the target excavation surface or a surface calculated from the target excavation surface and the operational plane of the work device 20 on the basis of the three-dimensional information of the target excavation surface and the current positional information of the construction machinery to extract a reference line L that is the intersecting line or a line calculated from the intersecting line as the two-dimensional information of the reference surface in the operational plane; and a characteristic point transmitter 35 for transmitting the Z-coordinates of characteristic points P1, P2, ..., Pn on the reference line L to an area limiting excavation controller 40 as the basic information. With the above structure, area limiting excavation control becomes highly efficient.
