Non-contact sleep state monitoring method and system based on biological microwave radar

Abstract

The invention relates to a non-contact sleep state monitoring method and system based on a biological microwave radar, and the method comprises the following steps: S1, enabling a microwave radar sensor to transmit a microwave signal to a to-be-monitored individual, receiving a radar echo signal, and carrying out the preprocessing of the radar echo signal, and obtaining radar original data; s2, performing radar signal processing on the radar original data to obtain a sleep body movement characteristic data set and a sleep state classification data set including physiological sign data; and S3, based on big data and an artificial intelligence algorithm, combining the sleep body movement characteristic data set and the sleep state classification data set to obtain a sleep state result of the to-be-monitored individual, and completing sleep state monitoring. Compared with the prior art, the non-contact sleep state monitoring method has the advantages of convenience, accuracy and the like.

Description

technical field [0001] The invention relates to the technical field of intelligent pattern recognition and physiological signal processing, in particular to a non-contact sleep state monitoring method and system based on biological microwave radar. Background technique [0002] With the development of social economy, people pay more and more attention to their own health. At the same time, with the advent of the era of 5G and the Internet of Everything, sensor devices for smart homes, human health monitoring, and medical care emerge in an endless stream. Real-time monitoring of human health has become The research hotspots of smart wearable devices, such as real-time monitoring of human breathing, heartbeat, blood pressure and other vital signs, among which the monitoring of human sleep status is a hot spot in this field of research. [0003] At present, most of the monitoring of human sleep status is to monitor the breathing rate and heart rate of the human body during slee...

Problems solved by technology

[0003] At present, most of the monitoring of human sleep status is to monitor the breathing rate and heart rate of the human body during sleep by wearing contact sensor equipment, so as to infer the sleep status of the human body, but such sleep status monitoring methods must wear contact sensors. sensor, with some inconvenience

In addition, the traditional visual image-based method is expensive to calculate, requires high lighting conditions, cannot penetrate or bypass obstacles, has poor anti-interference ability, and has defects such as the risk of leaking user privacy.

[0004] Therefore, the non-contact monitoring method has become a hot spot in the research of relevant scientific research institutions. Among them, the biological microwave radar just has the characteristics of non-contact, so the research on the human sleep state monitoring based on the biological microwave radar technology is increasing. The single monitoring of the human sleep state is easily affected by environmental factors, and the accuracy and reliability are not high. The monitoring of the human sleep state needs to combine body movement information and physiological characteristic data to obtain a high accuracy rate. Currently, in this field There are few studies on
