Abstract

The invention provides a weighing scale capable of measuring weight values of four corners and a method, and belongs to the technical field of weighing scales. The weighing scale comprises a weighingscale body and a bearing plate, and a weighing measuring device is arranged on the weighing scale body and comprises a plurality of weighing sensors arranged on the weighing scale body and analog-digital conversion chips connected with the weighing sensors; the bearing plate is located on the weighing ends of the weighing sensors; the weighing measuring device is connected with a microprocessor, the microprocessor is arranged on the weighing scale body and used for utilizing a plurality of difference AD values for calculating weights born by the weighing sensors according to the difference ADvalues, output by the analog-digital conversion chips, of the weighing sensors under different conditions, total weight of the human body is calculated according to the weight born by the weighing sensors, the intelligence degree of the weighing scale is improved, and the simplified and convenient weighing scale capable of measuring the weight values of the four corners is provided for a user.

Description

technical field [0001] The invention belongs to the technical field of weighing scales, and in particular relates to a weighing scale and a method capable of measuring weight values ​​of four corners. Background technique [0002] The function of the scale is mainly manifested in its essential purpose. It can accurately weigh the body's weight, and through the daily weight change, it can reflect the weight control of a certain period of time. Weight control is the basis of health management; [0003] Most of the existing weighing scales can be used for weighing and measuring. With the development of the Internet of Things and the smart health industry, more and more household weighing scales have added the function of health measurement. In addition to component analysis and heart rate measurement requirements, there is also an increasing demand for measuring body balance and the weight borne by the four corners of the scale at the end of the human scale. The existing scales...
