Title:
AN APPARATUS AND A METHOD FOR COMPENSATING TILT OF A WEIGHING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/000887
Kind Code:
A1
Abstract:
The present invention relates to an apparatus and a method for compensating tilt. The method for compensating tilt comprises the steps of, S1: generating a tilt compensation model f (θ) for a weighing system on basis of a gravity decomposition model, which is a trigonometric function; S2: obtaining a plurality of calibration data sets based on a calibration performed on the weighing system in a level state and in a tilted state; S3: calculating correlation between the plurality of calibration data sets and the tilt compensation model f (θ); and S4: substituting a measured tilt angle θ into the tilt compensation model f (θ), to calculate a compensated weighing weight based on an uncompensated measurement weight output of the weighing system. The apparatus and the method for compensating tilt proposed in the present invention can provide accurate tilt compensation for a weighing system.
