when the time point of getting to bed is obtained according to the air pressure information of the mattress, the air pressure sensor in the mattress detects the air pressure change of the mattress, the voltage signal is collected by an ADC (analog-to-digital converter) and converted into a pure digital change, for example, the ADC chip converts the voltage signal into a pure digital, such as 1000. The starting point in time when the rising peak air pressure difference is greater than 2000 is taken as the point in time when the user gets into bed in this embodiment.
And when the time point of getting to the bed is obtained according to the pulse information of the mattress, obtaining the voltage information according to the air pressure information, and obtaining the pulse information of the mattress according to the voltage information. If the voltage changes to rise, it is referred to as a rise pulse, and if the voltage changes to fall, it is referred to as a fall pulse. The air pressure sensor reports the statistical values of the server once every 10 seconds, and the statistical values can comprise the number of rising pulses, the number of falling pulses and real-time air pressure values.
If the ACD detects that the sum of the rising pulse value and the falling pulse value is larger than 10, the air pressure change of the bed is indicated, after the air pressure is balanced, if the latter one of the two air pressure values at the interval of 10s is larger than the former one, the action of getting on the bed is indicated, and the starting time point when the rising highest air pressure difference in the ADC is larger than 2000 is taken as the time point when the user gets on the bed.

When the ACD detects that the sum of the rising pulse value and the falling pulse value is larger than 10 during ADC detection, the fact that the air pressure of the bed changes is indicated, and after the air pressure is balanced, if the latter one of the two air pressure values at the interval of 10s is smaller than the former one, the fact that the action of getting off the bed occurs is indicated. And recording a time period from the maximum air pressure value being less than 20 as a first time period, and if the first time period is less than 60 minutes, determining the starting time of the first time period as the time point of getting out of bed.
In one embodiment, after the time point of getting on the bed is extended by the fourth time period, the obtaining of the air pressure difference between the air pressure values of two adjacent periods separated by the preset air pressure period is started. And when the time point of getting off the bed is advanced by a fourth time period, stopping obtaining the air pressure difference of the air pressure values of two adjacent periods separated by the preset air pressure period.

The time point of getting out of bed is taken as the time point of finishing sleep.
And taking the time point of getting on the bed and the time point of getting off the bed as the sleeping time of the whole sleep, and corresponding to the sleeping time of the whole sleep. And if the user wakes up for multiple times in the whole sleep, taking the sum of the sleep time of the whole sleep as the final sleep time and the sum of the sleep time of the whole sleep as the final sleep time.

light sleep quality (light sleep time length/(sleep time length standard ratio of light sleep) (2)
S26: and acquiring a sleep score according to the sleep algorithm formula, the deep sleep quality and the light sleep quality.
Obtaining a sleep score according to equation (3):
adjusting coefficient (3) for sleep score (basic score + deep sleep quality first weight + light sleep quality second weight)
Steps S25 to S26 are also explained below:
the whole sleep quality is divided into 3 types according to weight, wherein the sleep time is 0.35, the deep sleep is 0.4, and the light sleep is 0.25.
The whole process of calculating the sleep score is as follows: firstly, setting a basic score of 0.35, then obtaining the sleep quality of deep sleep and the sleep quality of light sleep, respectively multiplying the sleep quality of deep sleep and the sleep quality of light sleep by corresponding weights, and then adding the weights to obtain a final score.
For example, assume that the sleep duration is tt (obtained from the start sleep time and the end sleep time), the deep sleep duration is dt, and the light sleep duration is lt, so tt ═ dt + lt.
According to the length of normal standard sleep of a human body, the time is 8h, the deep sleep is 2h, therefore, according to the ratio of the deep sleep to the light sleep in the standard sleep, the second weight of the light sleep is 0.75, the first weight of the deep sleep is 0.25, and since the final integral Score is higher, the adjustment coefficient is finally added to be 0.9, the formula (3) is specifically expressed as a formula (4), wherein Score is the sleep Score.
Score＝(0.35+dt*0.4/(tt*0.25)+lt*0.25/(tt*0.75))*0.9 (4)
In an embodiment, the waveforms shown in fig. 3-5 can be obtained by the ADC, fig. 3 is a first waveform when the ADC acquires the user getting on the bed, fig. 4 is a second waveform when the ADC acquires the user turning action, and fig. 5 is a third waveform when the ADC acquires the user getting off the bed.
As shown in fig. 3, the air pressure change is converted into a voltage change by the air pressure sensor, and the voltage change value is collected by the ADC, and the voltage value is collected every 10 msec. If the voltage changes to rise, recording as a rising pulse C; if the voltage change is a fall, it is referred to as a fall pulse D.

If the sum of the detected values of C and D is more than 10, the air pressure change of the bed is indicated, after the air pressure is balanced, the value B is compared with the value A in the front 10 seconds, and if the value B is more than A, the action of getting on the bed is indicated.
As shown in figure 4, if the sum of the detected values of C and D is greater than 10, the air pressure change of the bed is indicated, after the air pressure is balanced, the value B is compared with the value A in the previous 10 seconds, and if the value B is approximately equal to the value A, the turning action is indicated.
