Title:
MOVEMENT IDENTIFICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/064777
Kind Code:
A1
Abstract:
Provided is a movement identification device that, in comparison to conventional movement identification devices, is capable of more accurately identifying a specific movement of a construction machine on the basis of output from sensors mounted to the construction machine. The movement identification device 100 comprises a waveform generation unit 111, a waveform storage unit 121, and a movement identification unit 112. The waveform generation unit 111 generates a force waveform that is based on a signal from a force sensor for detecting a force acting on the construction machine, and generates an orientation waveform that is based on a signal from an orientation sensor for detecting the orientation of the construction machine. The movement identification unit 112 stores a reference waveform that is a combination of a force waveform and an orientation waveform corresponding to a specific movement. A stress calculation unit 113 compares a movement waveform, which is the combination of a force waveform and an orientation waveform corresponding to an arbitrary movement by the construction machine, to the reference waveform stored in the waveform storage unit 121 and identifies the specific movement contained in the arbitrary movement by the construction machine.
