WIPO Patent Application WO/2022/209646
Kind Code:
A1
Abstract:
This work machine management system comprises a landform data generation system that generates landform data indicating a finished part made by a work device of a work machine on the basis of a detection result from a posture detection device that detects the posture of the work machine. The landform data generation system calculates a trajectory of the work device on the basis of the posture of the work machine, calculates information on a surface constituting the trajectory on the basis of the trajectory of the work device, generates construction history data by recording position information of the trajectory of the work device and the information on the surface constituting the trajectory for each of a plurality of grids obtained by dividing a predetermined region into a lattice, and generates landform data on the basis of the position information of the trajectory of the work device and the information on the surface constituting the trajectory included in the construction history data.
