Title:
WEIGHING DEVICE EQUIPPED WITH THREE-AXIS ACCELERATION SENSOR AND INSPECTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/047564
Kind Code:
A1
Abstract:
Provided are: a weighing device that is equipped with a three-axis acceleration sensor, automatically detects the temporal change of the three-axis acceleration sensor, and automatically solves a problem caused by the change; and an inspection method. 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). When any change has been detected as a result of comparison of outputs of the three-axis acceleration sensor along the three axes with the reference outputs, the arithmetic operation unit confirms the horizontality of the weight sensor, and then replaces the reference outputs stored in the storage unit with the current outputs of the three-axis acceleration sensor.
