Title:
WEIGHING DEVICE AND WEIGHING METHOD USING THREE-AXIS ACCELERATION SENSOR
Document Type and Number:
WIPO Patent Application WO/2023/026337
Kind Code:
A1
Abstract:
Provided is a weighing device and a weighing method that enable automatic solution of a problem caused by changes in three-axis directions by using a three-axis acceleration sensor. A weighing device (1) comprises: a weighing tray (11); a weight sensor (12) connected to the weighing tray; a three-axis acceleration sensor (20) that sets x and y on a plane parallel to the horizontal of the weight sensor and z in a direction perpendicular to the horizontal of the weight sensor, and detects acceleration changes in the three axes of x, y, and z; a storage unit (14) that stores reference outputs of the three-axis acceleration sensor along the three axes when the weight sensor is horizontally situated; and an arithmetic operation unit (13). The arithmetic operation unit compares currently-obtained outputs of the three-axis acceleration sensor in along the three axes with the reference outputs, detects existence of inclination when an output along x and/or y has been changed and existence of an installation place change when an output along z has been changed, and notifies of a user of the change.
