Non-contact sleep staging method

Abstract

The invention discloses a non-contact sleep staging method. The non-contact sleep staging method comprises the following steps of 1, filtering radar echo signals, and obtaining a respiration signal and a heartbeat signal separately; 2, according to the respiration signal, obtaining respirations per minute (RPM), variance of the respiration per minute (RPM Variance), according to the heartbeat signal, obtaining heartbeats per minute (BPM), variance of the heartbeat per minute (BPM Variance), and according to the respiration signal, obtaining a body movement signal; 3, conducting cluster analysis on the RPM, the RPM Variance, the BPM, the BPM Variance, and the body movement signal separately; 4, according to a sound signal, a video signal and obtained signals after the cluster analysis in the step 3, acquiring a division result of sleep states. According to the non-contact sleep staging method, medical workers can be helped to take treatment measures in time according to real sleep situations of patients. The non-contact sleep staging method has the advantages of being high in safety, high in precision, small in size and intelligent.

Description

technical field [0001] The invention belongs to the technical field of radar monitoring, in particular to a non-contact sleep staging method. Background technique [0002] Traditional breathing and sleep monitoring systems mainly rely on contact sensors and electrodes attached to the human body for measurement, so as to obtain real-time vital parameter signals of the human body. These methods require direct or indirect contact with the human body. This kind of contact measurement greatly restricts other methods. The scope of application, and the contact of the electrode also has a certain impact on the characteristic information of the living body, affecting the accuracy of its detection, and bringing pressure to the processing of the characteristic information of the living body. [0003] The existing breathing and sleep monitoring system needs electrodes or sensors to contact the living body, and cannot detect the life signal (respiration, heart rate, etc.) of the living b...

[0003] The existing breathing and sleep monitoring system needs electrodes or sensors to contact the living body, and cannot detect the life signal (respiration, heart rate, etc.) of the living body within a long distance. For patients with sleep apnea, newborn babies, certain Some people with sleep disorders cannot monitor their sleep status to predict possible emergencies
