Title:
DIAGNOSIS DEVICE, DIAGNOSIS METHOD, AND DIAGNOSIS PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/241468
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a diagnosis device, a diagnosis method, and a diagnosis program that make it possible to determine an occurrence status as well as the presence or absence of an abnormality in a driven object. Provided is a diagnosis device (50) for diagnosing a driven object (10) having a rotating shaft. The driven object (10) rotates by being driven by an external motor (20). The diagnosis device (50): calculates an estimated torque resistance value of a combination of the driven object (10) and the motor (20) on the basis of actual operation data obtained by driving the driven object (10) using the motor (20); obtains a three-dimensional table for the driven object (10) and the motor (20), the three-dimensional table containing angles, angular velocities, and estimated torque resistance values; obtains a reference-state three-dimensional table containing angles, angular velocities, and estimated torque resistance values in a reference state; and calculates a determination three-dimensional table from the difference between the three-dimensional table for the driven object (10) and the motor (20), and the reference-state three-dimensional table.
