8 can determine whether the pressure applied to each

11 is equalized in any one of the three ways described above.

In this embodiment, when it is determined that the pressure applied to each supporting

11 is unbalanced, the supporting force of each supporting

11 on the

5 of the human body is adjusted to balance the pressure applied to each supporting

11, which includes any one of the following items:

1. taking the pressure on the supporting

11 with the highest pressure among the supporting

11 as a first target pressure value, and adjusting the supporting force of the other supporting

11 on the

5 so as to make the pressure on the other supporting

Because

7 has soft comfortable, characteristics such as deformation strong adaptability, consequently, can regard as strutting

11 with

7, simultaneously be connected with baroceptor 9 and

10 on the

7,

8 is connected baroceptor 9 with

10 can pass through baroceptor 9 detects the atmospheric pressure of

7 with pass through

10 is

7 is inflated and is deflated in order to change the atmospheric pressure of

7. In this way, the

7 as the supporting

11 are arranged to form the

12 for supporting the

5, the supporting force of the supporting

11 on the

5 is the supporting force of the

7 on the

5, and the

8 can adjust the supporting force of the supporting

11 on the

5 by adjusting the air pressure of the

7. At this time, the calculation formula of the pressure received by the supporting

11 is P1-P2, where P is the pressure received by the air bag 7 (i.e. the pressure received by the human trunk 5), P1 is the air pressure of the

7, and P2 is the contraction pressure of the

7. For example, in fig. 2, the supporting point of the airbag a to the

5 is at a position a, and the supporting strength of the airbag a to the position is the air pressure of the airbag a minus the contraction pressure of the airbag a. The supporting point of the airbag B to the

5 is at the part B, the supporting point of the airbag C to the

5 is at the part C, and the supporting force of the airbag B to the part B of the

5 and the supporting force of the airbag C to the part C of the

5 can be calculated in the same way. The b part of the

7 corresponding to the position is larger than that of the

7 at other parts, the supporting strength of the

12 to the position is ensured to be consistent with that of the

7 at other parts, and the balance of the supporting strength of the

12 to each part of the

5 is ensured.

For an

7 whose contraction pressure is not constant but varies with the amount of inflation and is not linear with the amount of inflation, the amount of inflation of the

7 can be calculated by an

10 connected to the

7, and the contraction pressure of the

7 can be calculated from the amount of inflation of the

7 and a curve of the contraction pressure of the

7 with the amount of inflation. Here, the curve of the systolic pressure of the

7 according to the change of the inflation amount may be obtained by inflating the

7 by different amounts each time and detecting the systolic pressure of the

7 at each inflation amount, and then performing curve fitting according to the systolic pressure of the

7 at each inflation amount.

2 further comprises at least two

4 for detecting the sleeping posture of the human body. The at least two

4 are arranged at the positions for supporting the shoulders of the human body side by side at intervals, and the total width formed by arranging the at least two

4 side by side at intervals is smaller than the preset width of the shoulders of the human body and is larger than the preset thickness of the shoulders of the human body. The

8 is connected with at least two

4, the

8 is capable of receiving pressure data of each

4, the

8 is further configured to:

detecting pressure data of each

4 in real time;

judging whether the pressure data of each

4 is balanced;

when the pressure data of each

4 are equalized, the human body is judged to be in a lying posture, otherwise, the human body is judged to be in a side lying posture.

When the overall width formed by arranging the at least two

4 side by side at intervals is smaller than the preset width of the shoulders of the human body and is larger than the preset thickness of the shoulders of the human body, the human body can press all the

4 when lying flat, so that the pressure data of all the

4 are balanced, and when lying on side, all the

4 cannot be pressed, so that the pressure data of all the

4 are unbalanced, and whether the human body lies flat or lies on side can be judged according to whether the pressure data of all the

4 are balanced.

When it can be determined whether the human body lies down or lies on the side, the

8 may be further configured to count the number of times of turning over of the human body according to the number of times of switching the human body between the lying posture and the lying posture. The sleep quality of the human body can be further reflected by the turnover frequency.

Since all the

4 are pressed even if a human body lies on the

2, it is not possible to ensure that the pressures applied to the respective

4 are absolutely equal. Therefore, in the present description, the pressure data of each

4 is equalized, and it is not necessary that the pressure data of each

4 is completely equalized to indicate that the pressure data of each

4 is equalized, but the pressure data of each

4 is substantially uniform to indicate that the pressure data of each

4 is equalized. In view of this, the determination as to whether the pressure data of each

4 is equalized includes any one of:

1. judging whether the pressure data of each

4 is greater than a fourth preset value, if so, judging that the pressure data of each

4 is balanced, otherwise, judging that the pressure data of each

4 is unbalanced;
