Physiological index measuring method and system based on wireless radio frequency signals

Abstract

The invention discloses a physiological index measuring method and system based on a wireless radio frequency signal, and the method comprises the steps: eliminating noise in an original channel state information sequence, and obtaining channel state information sequence data; taking the channel state information sequence data as input, and segmenting the channel state information sequence data to obtain training data; performing data amplification on the training data; the channel state information data after data amplification is used as an input tensor of WiFi-Net, the channel state information data is converted into a feature map with a space coding mode through a generation stage, and the feature map with the space coding mode is further mapped into physiological perception task features through a feature learning stage; and estimating human body physiological indexes by using the physiological perception task features. No extra hardware cost is needed to replace an existing body fat scale to serve as a daily health monitoring tool of a user, and measurement of the body fat rate, the muscle rate, the bone content and the water content is achieved.

Description

technical field [0001] The invention belongs to the technical field of artificial intelligence of the Internet of Things, and in particular relates to a method and system for measuring physiological indicators based on wireless radio frequency signals. Background technique [0002] With the development of social economy and the improvement of living standards, people pay more and more attention to their own health. In the field of home health equipment, the body fat scale is a home device for users to detect body fat and muscle ratio, track exercise and fitness effects, and assist in managing diet plans, and has already gained a certain user coverage. When using existing body fat scales, users first need to remove their shoes and socks, and stand on the electrodes of the body fat scale with both feet. The electrodes and the human body form a current loop, estimate the strength of the current, estimate the resistivity of the human body, and infer the body fat of the user rat...

AI Technical Summary

Problems solved by technology

There are two main problems with this solution. The first is that the measurement process is cumbersome; the second is that the price of the body fat scale is much higher than that of ordinary scales, and users need to bear this part of the premium
