Problems solved by technology

The entire testing process is cumbersome, and it is easy to cause users to have the "first night effect"
At the same time, this kind of intrusive test also brings physical and psychological burden to the user, directly affecting the user's normal sleeping position data status

Abstract

The present invention provides a sleeping posture recognition method and device based on a piezoelectric ceramic sensor, which includes: when the user is in a stable sleep state, based on the piezoelectric ceramic sensor system, obtaining a mixed cardiac shock signal in the chest and abdomen area of ​​the user; Cardiac impact signal to determine the distribution characteristics of the user's cardiopulmonary activity; input the cardiopulmonary activity distribution characteristics and preset environment vector characteristics into the trained sleeping posture recognition and classification network model to obtain the user's sleeping posture recognition result. In the method of the present invention, when the user is in a stable state of sleep, the mixed cardiac impact signal collected by the multi-channel piezoelectric ceramic sensor in the chest and abdomen area of ​​the user is processed to obtain the distribution characteristics of the user's cardiopulmonary activity, so as to obtain the distribution characteristics of the cardiopulmonary activity Input the trained sleeping posture recognition and classification network model with the preset environment vector features to obtain the user's sleeping posture recognition results, realize non-invasive real-time user sleeping posture monitoring, and have strong universality and environmental anti-interference ability.

Description

technical field [0001] The invention relates to the technical field of sleep monitoring, in particular to a method and device for recognizing sleeping postures based on piezoelectric ceramic sensors. Background technique [0002] With the improvement of living standards, more and more people begin to pay attention to their sleep conditions. [0003] For sleep monitoring, the current common ways to monitor the user's sleeping posture and related data status include Poly Somno Graph (PSG) and Cyclic Alternating Pattern (CAP) during sleep, which assist video monitoring through gyroscopes The system judges the user's sleeping position throughout the night. This method is to obtain the user's physiological parameters through contact measurement. The user needs to wear more than a dozen electrodes and a tension sensor for testing all night to get a complete report. The entire testing process is cumbersome, and it is easy to cause users to have a "first night effect". At the sam...
