It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Example one
Referring to fig. 1 to 3, as shown in fig. 1 to 3, a method for monitoring a sleep state of a human body based on a mobile device includes: acquiring basic movement information of a first object, and restoring the detection equipment to an initial state before acquisition;
judging whether to start the sonar system according to the basic movement information of the first object:
if the sonar system is started, the sonar system detects an environmental noise variable;
and outputting sleep report information in combination with REM sleep according to the basic movement information and the ambient noise variable of the first object.
It should be noted that REM sleep, also called heterogeneous sleep (Para-sleep) or fast phase sleep, heterogeneous sleep or fast wave sleep, is a rapid eye movement. The eyeball is a sleep stage, and the eyeball can rapidly move involuntarily at the sleep stage. At this stage, the brain neurons are active as they were awake. Most lifelike dreams that can be recalled after waking up occur at REM sleep. It is the shallowest of all sleep stages, and people who wake up while REM sleeps will be different from those in other sleep stages, but full of alertness and mental fullness.
In addition, REM sleep usually occurs at the part of the transition from the deep sleep period to the shallow sleep period, so we adopt different calculation methods according to different data situations:
when the first object passes a longer deep sleep period and enters a shorter light sleep period, marking the time length of the second half of the deep sleep period which is less than 50 percent as first REM sleep, and the time length of single REM sleep is not more than 15 minutes;
when the first subject enters a longer light sleep period after a shorter deep sleep period, the first half of the light sleep period < 50% is marked as the second REM sleep, and the single REM sleep time length does not exceed 15 minutes.

it should be noted that both the displacement data and the sonar system data are acquired at a frequency not lower than every second, and in some special cases, at a millisecond frequency. The moving device tests show that the displacement difference is not obvious on the premise that the moving speed of the first object is accurate to the second, so that training data are measured in a unit of every n seconds and every n minutes in the model respectively, and the difference value of all detection data in the n seconds or n minutes is obtained by taking a MAX function or an AVERAGE function to obtain a determined value. After repeated pre-verification, the finally obtained modeling training formula is as follows:
moving the detection object in the X-axis direction, and obtaining a set of data (X1, X2, X3 … Xn) within n seconds or n minutes of moving, wherein the displacement difference in the X-axis direction is an array M (M1 ═ X1-X2|, M2 ═ X2-X3|, … Mn-1 ═ Xn-1-Xn |), and the value in the X-axis direction is MAX or AVERGAE (M1, M2 … Mn), the larger of the two;
meanwhile, obtaining a corresponding number sequence N and a corresponding number sequence P in the Y-axis direction and the Z-axis direction by using the same calculation method;
the number sequence N (N1 ═ Y1-Y2|, N2 ═ Y2-Y3| … Nn-1 ═ Yn-1-Yn |), the value in the final Y direction being MAX or AVERGAE (N1, N2 … Nn), the larger of the two;
the numerical sequence P (P1 ═ Z1-Z2|, P2 ═ Z2-Z3| … Pn-1 ═ Zn-1-Zn |), and finally the value in the Z axis direction is MAX or AVERGAE (M1, M2 … Mn), whichever is larger.

In one embodiment of the invention, when the displacement difference of the first object in the three directions of the coordinate X axis, the coordinate Y axis and the coordinate Z axis in the previous second and the next second is more than 0.05m-1 m; the sonar system is not activated.
In one embodiment of the invention, the preset information is carried out before the basic movement information of the first object is collected; the preset information includes: the magnitude of the displacement of the first object and the ambient noise variation in which the first object is located.

S104, if the first object does not carry the mobile equipment or the human body state is 'still/asleep', acquiring an environmental noise variable by using a sonar system; wherein the ambient noise variation is collected by a device microphone
And according to the environment noise variable, calculating the noise variable difference of the area where the mobile equipment is located to obtain the range value of the variable difference.
S105, according to the obtained noise variation difference, and in combination with the basic law that a basic model during sleep is supposed to be deep sleep, light sleep and clear-headed, presetting the sleep state of the first object as deep sleep, light sleep and clear-headed; and continuously correcting the variation difference in the monitoring process to enable the sleep state of the first object to continuously approach to the real sleep state.

For example, the ambient noise variance of the first subject is poor and the pre-performance of the sleep state, the collected ambient noise variance belongs to one of deep sleep, light sleep or awake in the personal behavior of the first subject. The thresholds for deep and light sleep are set in conjunction with the basic ambient noise, and the calculations are corrected for each complete monitoring of the first subject.
