Title:
作業機械の管理システム
Document Type and Number:
Japanese Patent JP7375259
Kind Code:
B2
Abstract:
A work machine management system includes a terrain profile data generating system configured to generate terrain profile data representing a finished shape produced by a work device of a work machine, on the basis of a sensing result of a posture sensor that senses a posture of the work machine. The terrain profile data generating system computes a trajectory of the work device on the basis of the posture of the work machine, computes information about a plane constituting the trajectory of the work device on the basis of the trajectory, generates construction history data by recording positional information of the trajectory of the work device and the information about the plane constituting the trajectory for each of a plurality of grids obtained by dividing a predetermined area in a lattice manner, and generates the terrain profile data on the basis of the positional information of the trajectory of the work device and the information about the plane constituting the trajectory, the positional information and the plane information being included in the construction history data.
