Title:
WORK ASSISTANCE SYSTEM FOR CONSTRUCTION MACHINE
Document Type and Number:
WIPO Patent Application WO/2024/024828
Kind Code:
A1
Abstract:
The present invention makes it possible to calculate the speed of rotation of a construction machine even when a sensor is mounted to a site that is not the center of rotation of the construction machine. A work assistance system S according to the present disclosure performs machine guidance based on an angular velocity 12ω relating to turning of a rotating-type hydraulic shovel 1. The work assistance system S comprises: an inertial sensor 2 that is disposed at a first position separate from the center of rotation 12C of a body 12 of the hydraulic shovel 1; and a control unit 33 that calculates the angular velocity 12ω of the body 12 on the basis of a measurement value of the inertial sensor 2 and a first distance D, which is the distance from the center of rotation of the body 12 to the inertial sensor 2.
