Title:
WEIGHT-BEARING MEASURING DEVICE AND METHOD, AND WEIGHT-BEARING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/047560
Kind Code:
A1
Abstract:
A weight-bearing measuring device. The device comprises: a weight sensor, comprising a deformable body (110) and a bridge circuit, wherein the deformable body (110) is configured to deform under the action of gravity on a borne object (710), and the bridge circuit comprises at least one resistance strain gauge (Rx) disposed on the deformable body (110) and is configured to generate an output voltage (U2) representing deformation under the action of an input voltage (U1); an acceleration sensor (200), configured to detect tri-directional acceleration components in three directions perpendicular to each other generated by the deformable body (110) under the action of gravity on the borne object (710); and a processing unit (300), configured to calculate the force of gravity and/or mass of the borne object according to the tri-directional acceleration components, the input voltage (U1), the output voltage (U2), and switching coefficients of the bridge circuit in the three directions. Also provided is a weight-bearing measuring method and a weight-bearing apparatus.
