3. The medical monitoring and interaction system according to claim 1, wherein the controller transmits the recuperation signal to the pressure analysis module when receiving the recuperation signal transmitted by the image analysis module, and the pressure analysis module transmits the recuperation signal to the data transmission module when receiving the recuperation signal transmitted by the controller.
4. The medical monitoring and interaction system according to claim 1, wherein after the pressure analysis module receives the recuperation signal, the pressure analysis module transmits and inputs a new preset value signal to the data transmission module, the new preset value signal specifically being: the head, back, buttocks and legs of the patient are preset with new weight distribution values for each area block pressed by the sickbed plate (1) when the patient lies on the sickbed plate (1); at this time, the weight distribution duty ratio of the pressing frequency variation difference Tjc and the real-time pressing pressure variation difference Xjc of the pressure analysis module is calculated according to a new preset value; the pressure analysis module uniformly calculates function consumption coefficients a, b, c and d of the function consumed by pressing the bed board by different areas of the head K1, the back K2, the buttocks K3 and the legs K4 of the patient according to new preset values.
