[0052] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0053] In one embodiment, Figure 1 As shown, a sleep aid method is provided. This embodiment uses the method applied to a terminal as an example. It can be understood that the method can also be applied to a server, and can also be applied to a system including a terminal and a server, and is implemented through the interaction between the terminal and the server. In this embodiment, the method includes the following steps:

[0054] Step 100: Collect the user's EEG data.

[0055] It can be understood that the user's EEG data can reflect the user's current state.

[0056] The traditional EEG acquisition and processing system includes input, amplification, filtering, analysis and other components. So far, there are mainly the following types of human EEG signal acquisition and processing.

[0057] Clinically, magnetic resonance imaging (MRI), positron emission tomography (PET) and clinical electroencephalography (EEG) are considered to be stable and reliable technologies for detecting human brain wave signals. The principle of MRI technology is to use the resonance of hydrogen nuclei in the cells of human tissues and organs under the action of a magnetic field, record the resonance trajectory and reconstruct the data. When brain nerve cells are stimulated, the blood supply to the corresponding brain area changes, and the magnetic susceptibility of the area changes, thereby obtaining the activity of regional brain neurons. The principle of PET technology is to obtain the distribution concentration of radionuclides in the cross-section of human tissues by examining the high-energy photons generated by the collision of radionuclides and electrons, but in essence it is a detection of tissue metabolic processes. EEG technology obtains electroencephalographic images based on the principle of electromagnetics. It determines whether neurons are active normally through changes in the magnetic and electric fields generated by the activity of neurons in the head, and also obtains the activity location and intensity of neurons.

[0058] Electroencephalogram (EEG) is a modern auxiliary examination method that uses an electroencephalogram recorder to amplify the weak bioelectricity of the brain into a curve to help diagnose diseases. In clinical applications, the earlobe, nose tip or mastoid is generally used as the zero potential point on the body. The potential difference between the electrode placed at this point and the electrodes at other parts of the scalp is the recorded EEG signal.

[0059] Step 110: determine the user's sleep stage based on the EEG data.

[0060] For example, in each sleep stage of a person, the EEG signal has different rules, so the result of judging the sleep stage of the user can be obtained from the EEG data of the user.

[0061] Step 120 , playing a preset audio file based on the user's sleep stage and outputting a preset low-frequency pulse to the user.

[0062] It is understandable that playing the preset audio file and outputting the preset low-frequency pulse to the user can be performed simultaneously or sequentially, and different modes can be selected according to actual conditions. For example, the application position of the low-frequency pulse signal can be selected from specific acupuncture points on the user's brain to achieve a better sleep-aiding effect.

[0063] The above-mentioned sleep-aiding method collects the user's EEG data; determines the user's sleep stage based on the EEG data; plays a preset audio file based on the user's sleep stage and outputs preset low-frequency pulses to the user to help the user fall asleep. It not only obtains the user's sleep state through analysis of the EEG data, and provides sleep assistance based on the sleep state, but also integrates the two technical means of music and low-frequency pulses to provide sleep assistance, thereby improving the sleep-aiding effect.

[0064] In one embodiment, collecting the user's EEG data includes collecting the user's EEG signals; performing signal processing on the EEG signals to obtain EEG data, and the signal processing includes at least one of amplification, filtering, coupling, notching, and AD conversion.

[0065] In one embodiment, determining the sleep stage of the user based on the EEG data includes: determining the sleep stage of the user based on at least one feature of the amplitude, frequency, and waveform of the EEG data. Preferably, determining the sleep stage of the user based on the amplitude, frequency, and characteristic waveform of the EEG data at the same time.

[0066] In one of the embodiments, playing a preset audio file based on the user's sleep stage and outputting preset low-frequency pulses to the user includes playing an audio file of a preset band based on the user's sleep stage; if it is detected that the user enters a preset sleep stage after playing the preset audio file of the preset band, continuing to play the audio file corresponding to the sleep stage; if it is detected that the user does not enter the preset sleep stage after playing the preset audio file of the preset band, continuing to play the audio file corresponding to the sleep stage and outputting low-frequency pulses of a voltage corresponding to the sleep stage to the user.

[0067] In one embodiment, playing a preset audio file based on the user's sleep stage and outputting a preset low-frequency pulse to the user also includes that the sleep stage includes the awake stage, the light sleep stage and the deep sleep stage; if the user is in the deep sleep stage, then stop playing the audio file and stop outputting the low-frequency pulse to the user. It is understandable that if the user enters deep sleep after receiving sleep assistance, that is, enters the N3 stage or REM stage of sleep, then no more sleep assistance is needed, and the audio file can be kept playing and the low-frequency pulse output can be stopped after a preset period of time, or it can be stopped immediately.

[0068] In one embodiment, outputting a preset low-frequency pulse to the user also includes detecting the temperature of the low-frequency pulse output location; if the temperature exceeds a preset threshold, the power of the low-frequency pulse is reduced. It can be understood that this is used to prevent the safety hazard to the user caused by local overheating during the low-frequency pulse electrical stimulation process.

[0069] In one embodiment, playing a preset audio file and outputting preset low-frequency pulses to the user based on the user's sleep stage also includes playing an audio file with a preset audio frequency, volume and duration based on the user's sleep stage and outputting a low-frequency pulse with a preset power, waveform, pulse width and duty cycle to the user.

[0070] Understandably, the EEG waveforms vary greatly when the brain is in different conditions (such as excitement, drowsiness, sleep, etc.). EEG waveforms can be divided into four basic types based on their frequency.

[0071] Delta wave: The frequency is 0.5 to 3.5 times per second, and the amplitude is 20 to 200 μv. Normal adults have almost no delta waves when awake, but delta waves may appear during sleep. It is generally believed that high-amplitude slow waves (delta waves or theta waves) may be the main manifestation of electrical activity when the cerebral cortex is in an inhibited state.

[0072] Theta wave: The frequency is 4 to 7 times per second, and the amplitude is 20 to 150 μv. Theta waves can appear when adults are sleepy. In early childhood, theta waves are commonly seen, and clear alpha waves appear after the age of ten.

[0073] α wave: The frequency is 8 to 13 times per second, and the amplitude is 20 to 100 μv. When a normal person is awake, quiet, and has their eyes closed, α waves can appear, and their amplitude changes from small to large, and then from large to small, and this repeated periodic change forms the "shuttle shape" of the α wave. Each α wave shuttle lasts about 1 to 2 seconds. When the subject opens his eyes or receives other exciting stimuli (such as mental arithmetic), the α wave disappears immediately and turns into a fast wave, which is called "α wave blocking". Therefore, it is believed that α waves are the main manifestation of electrical activity in the cerebral cortex when it is awake and quiet. Factors such as the frequency, amplitude, and spatial distribution of α waves are important indicators reflecting the functional state of the brain.

[0074] Beta waves: The frequency is 14 to 30 times per second, and the amplitude is 5 to 20 μv. Beta waves can appear when the subject opens his eyes to see things and thinks. It is generally believed that beta waves are the main manifestation of electrical activity when the cerebral cortex is in a tense and excited state.

[0075] During sleep, the EEG undergoes various changes, which vary with the depth of sleep. According to the different characteristics of the EEG, sleep can be divided into two states: non-rapid eye movement sleep (NREM sleep) and rapid eye movement sleep (REM sleep).

[0076] In the non-rapid eye movement sleep stage, the muscles of the whole body relax, there is no eye movement, and the visceral parasympathetic nerve activity is dominant. The heart rate and breathing slow down, the blood pressure decreases, the gastrointestinal motility increases, the basal metabolic rate is low, the brain temperature is slightly lower than when awake, and the total blood flow of the brain is reduced compared to when awake. Non-rapid eye movement sleep is divided into four stages according to its EEG characteristics, namely, the falling asleep stage, the light sleep stage, the moderate sleep stage, and the deep sleep stage. In the first stage of EEG, the waves are mainly θ waves, and there are no spindle waves or K complex waves. In fact, it is a transition stage from full wakefulness to sleep. The response to external stimuli is weakened, mental activities enter a floating state, and thinking is disconnected from reality; in the second stage, the brain waves are spindle waves and K complex waves, and the δ waves are less than 20%. In fact, people have entered real sleep; in the third stage, the δ waves in the brain waves account for 20% to 50%, which is a moderate deep sleep; in the fourth stage, the δ waves in the brain waves account for more than 50%, entering a deep sleep state, during which people are not easily awakened. Stages 3 to 4 of sleep are generally deep sleep, when the threshold for awakening is the highest.

[0077] During the rapid eye movement sleep stage, mixed-frequency desynchronized low-amplitude brain waves appear. Rapid eye movement, facial and limb muscles have many paroxysmal small twitches, sometimes there may be sucking movements of the lips, short sounds from the throat, athetosis, highly unstable visceral activity, irregular breathing, frequent changes in heart rate, increased gastric acid secretion, increased cerebral blood flow and metabolism, increased discharge activity of brain neurons in most areas, increased brain tissue temperature, and significantly increased brain oxygen consumption compared to wakefulness. The awakening threshold during rapid eye movement sleep is higher than that of NREM stage 1 sleep, and is between NREM stage 2 and 3 sleep.

[0078] During a full night of sleep, REM sleep and NREM sleep alternate for about 90 to 100 minutes, and this cycle of change is called a sleep cycle. Normal people first enter the NREM sleep period, and quickly enter the 2nd, 3rd, and 4th stages from stage 1 and continue. After 80-120 minutes of NREM sleep, the first REM sleep appears, and after a few minutes, the next NREM sleep enters, forming a cycle of NREM sleep and REM sleep. On average, REM sleep occurs every 90 minutes, and the closer to the end of sleep, the longer the duration of REM sleep gradually increases. Each time can last for 10-30 minutes. During the entire sleep period, this NREM-REM sleep cycle repeats 3-5 times. The stages of each cycle may not be complete, but they all start from stage 1. In the early morning, the depth of sleep in each cycle becomes shallower and no longer reaches stage 4. From the cyclic conversion of NREM sleep and REM sleep, it can be seen that the sleep process does not go from shallow to deep as soon as you fall asleep and continue until dawn, but deep and shallow, and deep and shallow sleep alternate continuously.

[0079] In addition to the study of sleep patterns, studies on some neurotransmitters and chemicals in the brain have found that: neurotransmitters in the brain, such as endogenous morphines (or endorphins), 5-HT (5-hydroxytryptamine), γ-aminobutyric acid (GABA), etc. have a calming and relaxing effect, which can restore a relaxed and pleasant healthy environment inside the brain; excitatory substances released by neurons, such as dopamine, acetylcholine, serotonin, etc. in the brain, can improve symptoms such as daytime mental fatigue, decreased attention, and decreased thinking caused by insomnia; stress hormones in the brain, including adrenaline (ADR), norepinephrine (NE), glucocorticoids (cortisol, corticosterone), angiotensin I (Aug positive), etc., can cause the brain to be in a state of tension and excitement, with phenomena such as increased heart rate and vasoconstriction.

[0080] According to the above rules, we can find that when a person is in deep sleep, the duration of NREM3 and 4 is longer, while the duration of REM is shorter. In addition, when the components in the brain that promote calmness and pleasure increase, and the components that make people feel nervous and excited are suppressed, the brain can get a good rest and is more conducive to deep sleep. The treatment of insomnia is basically based on this sleep principle.

[0081] Normal people experience several relatively stable states during sleep throughout the night. To better describe sleep, Rechtschaffen and Kales divided sleep into six stages (i.e., the R&K criteria) based on the performance of electroencephalogram (EEG), electrooculogram (EOG), and electromyography (EMG) during sleep: wakefulness (W), rapid eye movement (REM), and four non-rapid eye movement (NREM) sleep stages. NREM is further divided into sleep stage 1 (S1), sleep stage 2 (S2), sleep stage 3 (S3), and sleep stage 4 (S4). Sleep stages 1 and 2 are light sleep (LS), and sleep stages 3 and 4 are deep sleep (also called slow wave sleep (SWS)). At present, the R&K sleep staging standard revised by the American Academy of Sleep Medicine (AASM) in 2007 is widely used internationally. It combines the S3 and S4 stages in the R&K criteria into one stage, and uses W, R, N1, N2, and N3 to represent the wakefulness period, rapid eye movement sleep period, light sleep stage 1, light sleep stage 2, and deep sleep period, respectively.

[0082] During sleep, NREM and REM alternate, forming 4-6 NREM-REM sleep cycles, each lasting 90-120 minutes. During normal adult sleep, the sleep phases appear regularly in sequence, from W-N1-N2-N3-N2-REM, then repeating N2-N3-N2-REM, and so on, interconnected and repeating over and over again. The REM phase lasts about 100 minutes, accounting for 20%-25% of the total sleep time.

[0083] Exemplarily, sleep is divided into the following five stages: W stage (wakefulness), N1 stage (NREM1), N2 stage (NREM2), N3 stage (NREM3), REM stage. Among them, N1 and N2 belong to light sleep, N3 belongs to deep sleep, and REM stage also belongs to deep sleep, which is conducive to establishing new synaptic connections, promoting learning and memory activities and even the formation of innovative thinking, promoting the normal development of the nervous system, maintaining normal functions and repairing injuries. Dreams generally appear in this stage. Please refer to Table 1, which shows the characteristics of EEG signals in each sleep stage.

[0084] Table 1 EEG signal characteristics of each sleep stage

[0085]

[0086] See also Figure 2 , Figure 2 The figure is a schematic diagram of a sleep aid system corresponding to the sleep aid method of an embodiment of the present invention. Exemplarily, the sleep aid system includes an EEG acquisition module 210, a central control module 200, an audio module 230 and a low-frequency pulse module 220, wherein the central control module 200 includes a data processing unit and a control unit. Specifically, the EEG acquisition module 210 is used to collect the user's EEG data and input it into the data processing unit. The data processing unit determines the user's sleep stage based on the received EEG data. The control unit controls the audio module 230 to play the corresponding audio file based on the preset correspondence between the sleep stage and the audio information. The control unit controls the low-frequency pulse module 220 to work based on the preset correspondence between the sleep stage and the output signal parameters of the low-frequency pulse module 220.

[0087] It can be understood that collecting the user's EEG data includes collecting the user's EEG signal; performing signal processing on the EEG signal to obtain EEG data, and the signal processing includes at least one of amplification, filtering, coupling, notching and AD conversion. Specifically, the EEG acquisition module 210 includes at least one EEG acquisition channel. The specific form of the EEG acquisition module 210 is not limited here, but in order to facilitate the user to wear it to sleep, a portable acquisition device for collecting forehead EEG is often used. Its working principle is: after the user's EEG signal is collected by the EEG acquisition electrode, after passing through its internal parallel differential amplifier circuit and filtering circuit, the analog signal is amplified, and the amplified signal is filtered, coupled, notched and other series of processing by the EEG signal processing module, and finally the processed signal is transmitted to the AD conversion module. The AD conversion module converts different EEG signals into digital signals and transmits them to the main controller in the EEG acquisition module 210. The main controller sends the received EEG digital signal to the central control module 200 through wireless transmission according to a fixed transmission protocol and data format.

[0088] In another embodiment, determining the user's sleep stage based on EEG data includes: determining the user's sleep stage based on at least one feature of the amplitude, frequency, and waveform of the EEG data. Preferably, the user's sleep stage is determined based on the amplitude, frequency, and characteristic waveform of the EEG data at the same time.

[0089] In another embodiment, playing a preset audio file based on the user's sleep stage and outputting a preset low-frequency pulse to the user includes playing an audio file of a preset band based on the user's sleep stage; if it is detected that the user enters a preset sleep stage after playing the preset audio file of the preset band, then continuing to play the audio file corresponding to the sleep stage; if it is detected that the user does not enter the preset sleep stage after playing the preset audio file of the preset band, then continuing to play the audio file corresponding to the sleep stage and outputting a low-frequency pulse of a voltage corresponding to the sleep stage to the user. Figure 3 , Figure 3 It is a flow chart of a sleep aid method according to another embodiment of the present invention. Exemplarily, if the user has entered the N3 or REM sleep stage, no sleep aid is provided; if the user has not entered the N3 or REM sleep stage, a preset audio file corresponding to the sleep stage is played, and if the sleep aid achieves the preset effect after playing for a preset time, the corresponding preset audio file continues to be played, and if the preset sleep aid effect is not achieved, a preset low-frequency pulse is output to the user. It is understandable that the preset sleep aid effect here can be set in advance by the user. For example, it can be set that if the user is originally in the N1 stage, the user enters the N2 stage after playing the preset audio file for a period of time, then the preset effect is achieved. The specific setting method can be determined according to the actual situation and is not limited here.

[0090] See also Figure 4 , Figure 4FIG. 1 is a flow chart of a sleep aid method according to another embodiment of the present invention. In this embodiment, if it is detected that the user needs sleep aid, a preset audio file is played simultaneously and a preset low-frequency pulse is output to the user.

[0091] In another embodiment, playing a preset audio file based on the user's sleep stage and outputting a preset low-frequency pulse to the user also includes the sleep stage including the awake stage, the light sleep stage and the deep sleep stage; if the user is in the deep sleep stage, stop playing the audio file and stop outputting the low-frequency pulse to the user. It can be understood that if the user enters a deep sleep after receiving sleep assistance, that is, enters the N3 or REM sleep stage, then there is no need for sleep assistance, and the audio file can be kept playing and the low-frequency pulse output can be stopped after a preset period of time, or it can be stopped immediately. Specifically, the awake stage is the W sleep stage, the light sleep stage is the N1 and N2 sleep stages, and the deep sleep stage is the N3 and REM sleep stages.

[0092] See also Figure 5 , Figure 5 The structure diagram of the low-frequency pulse module 220 of the sleep aid method according to an embodiment of the present invention is shown. Specifically, the low-frequency pulse module 220 is connected to the central control module 200 via wireless communication, and the low-frequency pulse module 220 includes a low-frequency pulse output unit 224, a low-frequency signal driving circuit unit 223, a main controller 222, a wireless receiving unit 221, and a power supply. Among them, the power supply is divided into a driving power supply 226 and a working power supply 225, wherein the driving power supply 226 is used to power the low-frequency signal driving circuit unit 223, and the working power supply 225 is used to power the main controller 222. The power supply adopts a rechargeable battery, which is convenient to carry and has a charge and discharge protection function.

[0093] For example, in the entire control system, the low-frequency pulse module 220 receives the instruction of the central control module 200 to start the low-frequency pulse signal output through the wireless receiving unit 221, analyzes the instruction data, drives the low-frequency signal output according to the data protocol, and uploads the characteristics and parameters of the output signal to the central control module 200 through wireless transmission. In this embodiment, the low-frequency pulse output module can be in the form of ear clips, and the two ear clips are respectively added to the two ears of the user. In other embodiments, the low-frequency pulse module 220 can be in other ways, such as electrodes applied to specific acupuncture points on the user's brain, etc., as long as the effect of applying low-frequency pulses to the user is achieved.

[0094] In another embodiment, outputting a preset low-frequency pulse to the user also includes detecting the temperature of the low-frequency pulse output position; if the temperature exceeds a preset threshold, the power of the low-frequency pulse is reduced. Specifically, the low-frequency pulse output unit 224 is also provided with a temperature sensor to prevent the safety hazard to the user caused by local overheating during the low-frequency pulse electrical stimulation. The detected temperature of the temperature sensor is transmitted to the central control module 200 via the main controller 222. When the detected temperature exceeds the preset threshold, the central control module 200 controls the low-frequency pulse module 220 to reduce the output power. The priority of this control is higher than the priority of regulating the signal parameters of the low-frequency pulse module 220 based on the sleep stage.

[0095] In another embodiment, based on the user's sleep stage, playing a preset audio file and outputting a preset low-frequency pulse to the user further includes playing an audio file with a preset audio frequency, playback volume, and playback duration, and outputting a low-frequency pulse with a preset power, waveform, pulse width, and duty cycle to the user based on the user's sleep stage. Figure 6 , Figure 6 The figure is a flowchart of playing a preset audio file in a sleep aid method according to an embodiment of the present invention. It can be understood that the audio module 230 is in communication with the central control module 200, and the audio module 230 is provided with one or more audio file libraries, each of which includes at least one audio file, and each audio file library has a preset corresponding relationship with the sleep stage. Exemplarily, the audio module 230 can be integrated with the central control module 200 in a computer device or a mobile terminal, for example, it can be embedded in a handheld device with an operating system such as a tablet computer / mobile phone, and is integrated with the entire system. Specifically, the central control module 200 controls the audio module 230 to play the audio file matching the result according to the result of sleep staging. The audio module 230 stores isochronous audio files with playing frequency bands of α band, θ band and δ band respectively. When the user is in the W stage of sleep, the central control module 200 controls the audio module 230 to play the isochronous audio file of α band; when the user enters the N1 stage of sleep, the central control module 200 controls the audio module 230 to play the isochronous audio file of θ band and reduces the volume by 50%; when the user enters the N2 stage of sleep, the central control module 200 controls the audio module 230 to play the isochronous audio file of δ band and reduces the volume by 50%; when the user enters the N3 stage or REM stage of sleep, the audio file is stopped after playing for a period of time or stopped immediately. It can be understood that isochronous audio, also known as rhythm transmission audio, achieves the effect of brain pulse transmission through audio transmission. Compared with the pulsation of both ears, isochronous audio can achieve good results directly through audio external playback without the help of headphones. In other embodiments, audio files of other bands may be added as long as they have a sleep-inducing effect.

[0096] Exemplarily, according to the sleep staging result, the central control module 200 controls the low-frequency pulse module 220 to generate a matching sleep-aiding low-frequency pulse signal, mainly outputting a 0.5HZ pulse low-frequency signal, and outputting different pulse voltage signals for different sleep states. There are a total of 5 different signal voltage levels corresponding to different sleep stages, and the low-frequency pulse output voltage corresponding to the W stage to the REM stage decreases in sequence. The following is an exemplary corresponding relationship:

[0097] W phase: 13-15V;

[0098] N1 stage: 10-13V;

[0099] N2 stage: 6-10V;

[0100] N3 or REM stage: 0-6V. When in N3 or REM stage, the low-frequency pulse module 220 automatically stops working after a preset period of time.

[0101] In other embodiments, the power, waveform, pulse width and duty cycle of the low-frequency pulse can be adjusted according to actual conditions, as long as the sleep-aiding effect is achieved.

[0102] See also Figure 7 , Figure 7 The figure is a schematic diagram of an application scenario of a sleep aid method according to an embodiment of the present invention. Specifically, the EEG acquisition module 210 (EEG acquisition) is fixed on the forehead of the user, and the collected EEG signal is transmitted to the central control module 200 provided in a computer or mobile terminal through wireless transmission after AD conversion. The data processing unit in the central control module 200 obtains the current sleep stage of the user after further processing, and the control unit controls the audio module 230 and the low-frequency pulse module 220 to assist sleep based on the sleep stage.
