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 invention provides a sleeping posture recognition method and device based on a piezoelectric ceramic sensor, and the method comprises the steps: obtaining a mixed heart impact signal of a chest and abdomen region of a user based on a piezoelectric ceramic sensor system under the condition that the user is in a stable sleep state; determining cardiopulmonary activity distribution characteristics of the user based on the mixed heart impact signal; and inputting the cardiopulmonary activity distribution features and preset environment vector features into a trained sleeping posture recognition classification network model to obtain a sleeping posture recognition result of the user. According to the method, under the condition that a user is in a stable sleep state, mixed heart impact signals of a thoracic and abdominal area of the user are collected through a plurality of piezoelectric ceramic sensors, and the heart and lung activity distribution characteristics of the user are obtained through signal processing; and the heart and lung activity distribution features and the preset environment vector features are input into a trained sleeping posture recognition classification network model, the sleeping posture recognition result of the user is obtained, non-intrusive real-time user sleeping posture monitoring is achieved, and high universality and environment anti-interference capacity are achieved.

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...
