The invention relates to a membrane structure space capable of adjusting the pressure intelligently. The membrane structure space comprises a supporting and fixing device, a membrane body, pressure adjusting equipment and power equipment. The membrane body is located in the supporting and fixing device; the pressure adjusting equipment is connected with the power equipment, one set of pressure adjusting equipment is installed on a main chamber, the other set of pressure adjusting equipment is installed on the transition room, and the dynamically balanced pressure and oxygen environment are provided for the membrane structure. The membrane body comprises the main chamber, the transition room, a diaphragm, a connecting chamber and door bodies, the main chamber is connected with the transition room through the diaphragm, the connecting chamber is of a telescopic folding structure and is installed at one side of the transition room, and the door bodies are installed on the main chamber and the transition room respectively. Accordingly, the technical problems that the membrane is connected and fixed to a hard material, an oxygen chamber structure is single, installation is inconvenient, it is inconvenient to enter or exit from the oxygen chamber structure, operation is inconvenient, and the safety factor is low are successfully solved.
