Abstract

The invention provides a sleep state detection method, device and system based on an electroencephalogram collection head ring, and the method comprises the steps: obtaining EEG electroencephalogram signals of an FP1 electrode and an FP2 electrode in a 10-20 international standard lead system; the EEG electroencephalogram signals are processed, and EEG epoch signals of 30 s are obtained; and inputting the 30s EEG epoch signal into a trained electroencephalogram staging attention mechanism model, and obtaining a sleep stage staging result output by the electroencephalogram staging attention mechanism model. According to the sleep state detection method, the sleep state of the user can be obtained through collection and data analysis of electroencephalogram signals, and then reference can be provided for the user to know the sleep health state of the user.

Description

technical field [0001] The invention belongs to the field of sleep detection, and in particular relates to a sleep state detection method, device and system based on an EEG acquisition headband. Background technique [0002] Sleep is one of the most important physiological activities of human beings, and good sleep is beneficial to human beings to maintain their health. But with the progress of the times, people's pressure on work, study and life also increases, and more and more people suffer from sleep disorders. Sleep disturbances can cause many problems, including fatigue, anxiety, depression, and risk of death, and are a public hazard. Sleep disorder is a common disease in sub-healthy people, manifested as poor sleep quality, insomnia, etc., and may induce various cardiovascular and cerebrovascular diseases. According to the World Health Organization's 2019 survey data, more than 300 million people in my country have sleep disorders, among which the incidence of insom...
