WIPO Patent Application WO/2023/210133
Kind Code:
A1
Abstract:
Provided is an attachment position determination method for a boom angle sensor (41) that detects the attitude of a boom (10) on a work implement (3) having the boom (10), the attachment position determination method comprising: acquiring a straight line (L1) connecting a boom foot (10a) and a boom top (10b) of the boom (10) according to design; acquiring a flexure curve (C) in a flexed state of the boom (10) that is determined on the basis of the straight line (L1); acquiring a straight line (L2) connecting the boom foot (10a) and the boom top (10b) on the flexure curve (C); acquiring an angle (α) formed by the straight line (L1) and the straight line (L2); acquiring an angle (β) formed by the straight line (L1) and a tangent line to the flexure curve (C); determining, as a reference position (P6'), a position on the flexure curve (C) at which the angle (β) is equal to the angle (α); and determining an attachment position (P10) of the boom angle sensor (41) on the boom (10) on the basis of position information in the longitudinal direction of the boom (10) among position information of the reference position (P6').
