Embodiment 1

[0048] The flow chart is attached figure 1 Shown: a music-induced sleep method based on EEG signals, including the following steps:

[0049] Music grading step: analyze the three inherent parameters of music frequency, short-term energy, and sub-band energy ratio to form a music feature vector, process the music in frames, and obtain the maximum, minimum, and average values ​​of short-term energy and variance; the sub-band energy ratio analysis method is to use wavelet transform to divide the music signal into sub-bands, decompose it into multiple bands, use the sub-band energy ratio characteristics of multiple bands as a part of the music feature vector, and divide the music signal according to the music feature vector Music is divided into two levels. One of the levels corresponds to waking periods and the other corresponds to light sleep states (NREM stage 1 and NREM stage 2).

[0050] Signal collection step: collecting the user's EEG signal;

[0051] Signal processing s...

Abstract

The invention belongs to the field of the auxiliary sleeping, and discloses a music induction sleeping method and system based on an electroencephalogram signal. In allusion to the technical problem of a current method for sleeping monitoring that the corresponding relation between the music and the sleeping state is not adequately considered, and certain tracks cannot produce the better induction sleeping effect to certain users, the music induction sleeping method based on the electroencephalogram signal comprises the following steps: a step of music grading, a step of signal collecting, a step of signal processing, a step of sleep staging, a step of track selecting, a step of automatic tracking and a step of automatic stopping. The music induction sleeping system based on the electroencephalogram signal comprises a collecting module, a wireless transmitting module and an intelligent terminal. The intelligent terminal comprises a communication module, a processing module, a storage module and a playing module. The collecting module is used for collecting the electroencephalogram signal of a user and transmitting the electroencephalogram signal to the wireless transmitting module. The wireless transmitting module is used for transmitting the electroencephalogram signal collected by the collecting module to the communication module.

Description

technical field [0001] The invention relates to the technical field of sleep aids, in particular to a method and system for music-induced sleep. Background technique [0002] Sleep is necessary for all people. Most people spend one-third of their lives in sleep. Sleep is inseparable from people's physical and psychological functions, and it is very important to the health of the human body, normal life and other activities. Normal work has a significant impact. After sleep, fatigued nerve cells can be restored to normal physiological functions, and people's mental and physical strength can be restored. [0003] According to the World Health Organization's survey of more than 20,000 people in primary medical care in 14 countries, it was found that 27% of them had sleep problems. According to the sleep survey results released by the Chinese Sleep Research Association, the incidence of insomnia among Chinese adults is 38.2%. Occasional insomnia does not cause much damage to ...
