Computation device and computation method of basic information for excavation area-limiting control, and construction equipment
Provided is a basic information computation device (30) which computes basic information for area-limited excavation control to control an operating machine (20) of construction equipment such that excavation does not exceed a target excavation surface, the apparatus being provided with: a target surface storage device (33) which stores three-dimensional location information of a target excavation surface; a two-dimensional information extraction device (34) which, on the basis of three-dimensional location information of a target excavation surface and current location information of the construction equipment, calculates a line of intersection of the operating plane (20) of the operating machine and the target excavation surface or a reference surface which is a surface based thereon, and which extracts the line of intersection or a reference line (L) which is a line based thereon, as two-dimensional information of a reference surface on a plane of motion; and a feature point information transmission device (35) which transmits Z coordinates of a plurality of feature points (P1, P2 ... Pn) on the reference line (L) as basic information to an area-limited excavation control device (40). Highly efficient excavation area-limiting control can be achieved thereby.
