When in actual use, the pillow body 1 and the monitoring pad 2 are laid on the bed together, when a human body lies on the pillow, the back of the human body is covered on the monitoring pad 2, and because the human body has certain conductivity, when the human body covers the sensing piece, the electrical parameters of the sensing piece can be influenced to change, and when the area of the sensing piece is covered by the human body, the electrical parameters of the sensing piece can also change correspondingly. The area of the back of the human body covering the monitoring pad 2 is different under different lying postures, wherein when the human body is in a supine posture, the area of the back of the human body covering the monitoring pad 2 is larger; when the human body is in the lateral lying posture, the area of the human body back covering the monitoring pad 2 is small.

When the human body is not lying on the monitor, the sensing piece outputs an original electrical parameter, and the controller 3 stores the original electrical parameter as a preset electrical parameter; when a human body lies on the monitoring pad 2, the sensing piece senses the area of the back of the human body covering the monitoring pad 2 and outputs corresponding electrical parameters, and when the area of the back of the human body covering the monitoring pad 2 changes, the electrical parameters output by the sensing piece correspondingly change. The controller 3 receives the electrical parameter generated by the sensing element, and compares the received electrical parameter with a preset electrical parameter, so as to judge the current posture of the human body according to the result of the calculation and comparison.

After the controller 3 judges the sleeping posture of the human body, the lifting mechanism 7 is controlled to inflate or deflate the inflation tube so as to increase or decrease the thickness of the pillow body 1;
