Abstract

The invention discloses a sleep analysis method and device. The method includes the steps that multi-axis accelerated speed data collected within each subsidiary monitoring period of a person to be monitored are acquired according to the preset sampling frequency; based on the multi-axis accelerated speed data collected within each subsidiary monitoring period of the person to be monitored, the activity of the person to be monitored within each subsidiary monitoring period is determined; for each subsidiary monitoring period, according to the activity in a subsidiary monitoring period included in a period window corresponding to the subsidiary monitoring period, the activity characteristic value of the person to be monitored within each subsidiary monitoring period is determined, and a dynamic threshold value of the activity characteristic value within the monitoring period is determined as well; the activity characteristic value within each subsidiary monitoring period is compared with the dynamic threshold value, so that a first sleep analysis result of the person to be monitored in a sleeping state or a waking state within each subsidiary monitoring period is acquired. By the adoption of the method, waking and sleeping classification accuracy is improved.

Description

technical field [0001] The invention relates to the field of signal analysis, in particular to a sleep analysis method and device. Background technique [0002] Sleep research is an important part of sleep science and electroencephalography, and it is also one of the hot spots of scientific research in the world today. Polysomnography monitoring is currently the internationally recognized "gold standard" for sleep monitoring. Through electrodes attached to the body of the person to be monitored, the blood oxygen, ECG, eye movement, leg movement, EEG and other indicators are recorded to monitor Judge the sleep condition of the person to be monitored. However, polysomnography monitoring equipment is expensive. With the advancement of science and technology, the research on sleep monitoring is gradually developing in the direction of miniaturization and familyization. By collecting multi-axis acceleration data during the user's sleep, the user's acceleration during sleep is s...
