Center-of-gravity measurement human body electronic scale and measurement method

Abstract

The invention discloses a center-of-gravity measurement human body electronic scale and a measurement method. The electronic scale includes a scale surface. The scale surface is provided with a standing position A and a standing position B. A sensor S1, a sensor S2, a sensor S3 and a sensor S4 are respectively arranged at the upper left corner, the lower left corner, the lower right corner and theupper right corner of the bottom of the scale surface sequentially. The four sensors are connected in series to form a bridge with a power supply contact point and six signal measurement points. No additional center-of-gravity measurement sensor is required, the circuit structure is simple and the production cost is low. The bridge constituted by the four sensors can be measured, and output relationships among the four sensors can also be respectively measured to obtain the respective outputs of the four sensors. By setting an algorithm, the weight of a human body can be calculated, a human body center-of-gravity coefficient and a human body center-of-gravity position can further calculated. The invention is very helpful for people to pay attention to health and prevent diseases, and hasa very important significance especially for the prevention of spinal cord bending and correction.

Description

technical field [0001] The invention relates to a weighing apparatus, in particular to a four-point center-of-gravity measuring human body electronic scale and a measuring method. Background technique [0002] From a mechanical point of view, the standing posture of human beings with two feet is very abnormal, but human beings can easily maintain the standing posture. This is because some so-called postural muscles are continuously contracted and tense. Postural muscles can be considered as the back of the body and the waist and abdomen. All the muscles that pull a person from a crawling position to an upright position can maintain stability even if there is no foundation or the base area is small. In fact, the muscles or organs of all parts of the body tend to atrophy due to the action of gravity, but this phenomenon is also avoided by the postural muscles. Many people now have physical problems, such as low back pain, shoulder and neck pain, knee pain, high blood pressure...

AI Technical Summary

Problems solved by technology

The electronic scale for measuring the center of gravity in the prior art needs to add more than four independent sensors. Correspondingly, the control chip also needs to have an additional four analog signal input ports, which makes the circuit structure of the electronic scale for measuring the center of gravity more complicated. , and high production cost
