In step S102, a change in brain wave value and a change in body movement frequency of the sleeper are measured according to the brain wave acquisition command and the pulse current input command, and a sleep state of the sleeper is determined;

sleep has a biological rhythm, and international sleep medicine divides sleep stages into five stages, namely, a sleep onset stage, a light sleep stage, a sound sleep stage, a deep sleep stage and a rapid eye movement stage, wherein brain wave images in the sleep onset stage, the light sleep stage, the sound sleep stage, the deep sleep stage and the rapid eye movement stage have different frequency characteristics; the body movement frequency detection is matched with the periodic monitoring of the change of the wave value of the brain waves, so that the sleeping state of a sleeper in different sleeping stages is comprehensively judged, and the periodic limb movement in sleeping is a pathological change, which means that the recurrent and stereotyped limb movement appears in the sleeping process and is in a resting state in the intermittent period of the attack, so that the more frequent the body movement frequency is, the worse the sleeping state of the sleeper is.

In step S103, adjusting a pulse current input condition and a white noise playing condition accepted by the sleeper based on the sleeping state of the sleeper, wherein the pulse current input condition and the white noise playing condition include frequency information and intensity information;

In one embodiment, as shown in fig. 2, in step S102, the method for determining the sleep state of the sleeper by measuring the change of the brain wave value and the change of the body movement frequency of the sleeper according to the brain wave collecting command and the pulse current input command includes the following steps S201 to S203:

in step S211, collecting the brain wave value of the sleeper, and time-stamping the brain wave value of the sleeper in real time;

in step S212, intercepting all the electroencephalogram values within a fixed period of time, and generating an electroencephalogram in which the electroencephalogram values vary with time within the fixed period of time;

establishing a plane coordinate system by taking time change as an X axis and brain wave values as a Y axis, for example, obtaining brain wave numerical values S by taking every 1 second as a detection standard, recording to obtain S1, S2 and S3.. SN, connecting the brain wave numerical values S1, S2 and S3.. SN corresponding to different times to obtain a brain wave oscillogram, and setting the interval time period to be 5 seconds to obtain the brain wave oscillograms of S1-S5, S2-S6, S3-S7.. And the like which change along with time in a fixed time period;

in step S213, comparing the time-varying electroencephalogram waveform with waveforms of different sleep stages within the fixed time period, and selecting a sleep stage corresponding to the sleep stage waveform with the highest similarity;

sleep medicine divides sleep stages into five stages: the sleep onset period is the beginning of sleep, the feeling of drowsiness belongs to the period, and at the moment, the brain wave begins to change, the frequency is gradually slowed, and the amplitude is gradually reduced; the sleep stage is a light sleep stage, brain waves gradually go irregularly at the time, the frequency and the amplitude are suddenly changed, and occasionally, high-frequency and large-amplitude brain waves called sleep spindles and low-frequency and large-amplitude brain waves called K junctions occur; the deep sleep period and the deep sleep period are sleeping stages, the tested object is not easy to wake up, at the moment, brain wave changes greatly, the frequency is only 1 to 2 weeks per second, but the amplitude is increased greatly, and a curve with slow change is presented; the brain wave in the rapid eye movement period is changed rapidly, high-frequency and low-amplitude brain waves similar to the brain waves in the waking state appear, but saw-tooth-shaped waves with distinct characteristics exist in the brain waves, a sleeper usually has the action of turning over and is easy to awaken, the sleeper seems to enter the stage 1 sleep, but actually enters a sleep stage called rapid eye movement sleep, the sleep stages are all provided with change rules with different amplitudes and frequencies, and the current sleep stage can be judged according to the change of the rules.

In one embodiment, as shown in fig. 2, in step S102, the method for determining the sleeping state of the sleeper by measuring the change of the brain wave value and the change of the body movement frequency of the sleeper according to the brain wave collecting command and the pulse current input command further includes the following steps S221 to S223:

in step S221, body movement amplitude information of the sleeper is collected, and body movement amplitude information within a sleep setting range is recorded;

in step S222, adding a timestamp to the recorded body motion amplitude information of the sleeper within the sleep setting range, and calculating the body motion frequency of the sleeper within a fixed time period;

it is worth to be noted that the body motion amplitude information caused by the respiration of the sleeper is lower than the body motion amplitude information in the sleep setting range, the body motion amplitude information which is not in line with the sleep state and is made by the sleeper in the waking state is higher than the body motion amplitude information in the sleep setting range, and the two do not belong to the body motion amplitude information category to be acquired, so that the body motion amplitude information category only records the information of reasonable body motion amplitude;

in step S223, if the body movement amplitude information or the body movement frequency exceeds the sleep setting range, terminating the execution of the pulse current input command and the white noise playing command;

when a sleeper lies on the sleep pillow 100, the breathing action of the sleeper can cause slight change of the body position, whether the sleep pillow 100 is in a working state or not can be judged based on the change, when the sleep pillow 100 is in the working state, the pulse current is in an input state, the white noise is in a playing state, otherwise, when the head of the sleeper leaves the sleep pillow 100, the pulse current and the white noise are in a closing state, unnecessary electric energy loss can be prevented, manual closing is not needed, and the sleep pillow is more intelligent; when a sleeper lies on the sleep pillow 100, if the body movement amplitude information is far higher than the body movement amplitude information or the body movement frequency is far higher than the body movement frequency within the sleep setting range, it can be determined that the sleeper is in a waking state, and in this state, the pulse current and the white noise are in a closed state until the monitoring result shows that the sleeper is in a sleep waiting state, that is, the body movement amplitude caused by respiration is relatively stable, the pulse current and the white noise are turned on again.

In one embodiment, as shown in fig. 3, in step S103, the adjusting the pulse current input condition and the white noise playing condition accepted by the sleeper based on the sleeping state of the sleeper includes frequency information and intensity information, including the following steps S301 to S302:

in step S301, when the sleep stage corresponding to the sleep stage waveform chart changes, the pulse current input frequency and the white noise playing frequency change relatively;

as shown in step S213, the amplitude and the vibration frequency of the brain wave waveforms in different sleep stages are different, and by applying the pulse current and the white noise with the same frequency as the current sleep stage, the brain receives the pulse current and the white noise with the same frequency, so that different sleep stages can be induced to continue to operate, and the sleep duration can be effectively prolonged;

in step S302, when the frequency of the body movement or the average body movement amplitude of the sleeper in a fixed time period changes, the pulse current input intensity and the intensity of white noise playing are adjusted proportionally;

the fixed time period can be 5-60 seconds, and in different sleep stages, the body motion frequency is set to be N, the body motion amplitude is G, the average amplitude G is the ratio of the sum of G1 and G2.. To N, the standard body motion frequency is smaller than NA, and the standard body motion amplitude is smaller than GA;

if N is smaller than NA and the average amplitude G is smaller than GA, the input intensity of the pulse current and the playing intensity of the white noise are not changed;

if N is smaller than NA and the average amplitude G is larger than GA, the ratio of the sum of G1 and G2 to GA x N is the amplification factor of pulse current input intensity and white noise playing;

if N is larger than NA and the average amplitude G is smaller than GA, the ratio of N to NA is the pulse current input intensity and the amplification factor of white noise playing;

if N is larger than the average amplitude G of NA and larger than GA, the sum of G1 and G2.. And the sum of the ratio of GA x N and the ratio of N to NA are the amplification times of pulse current input intensity and white noise playing;

the direct proportional adjustment relationship between the pulse current input intensity and the white noise playing intensity and the body motion frequency or the average body motion amplitude is only one embodiment of the present application, and the direct proportional adjustment relationship between the pulse current input intensity and the white noise playing intensity and the body motion frequency or the average body motion amplitude is not limited to this embodiment, and may be adjusted by other algorithms.
