[0002] With the rapid development of technology in the fields of aviation, medicine and sports, the performance requirements for controllable air pressure cabins are getting higher and higher. However, the existing controllable air pressure cabin structures have many shortcomings in terms of applicability, space size, safety and pressure difference handling capabilities, making it difficult to meet the actual needs of various fields.
[0003] In military, civil, medical, scientific research, industrial production and testing, it is often necessary to increase or reduce the air pressure in a specific environment and combine it with the corresponding temperature, humidity and oxygen content to carry out various experiments, research, training and equipment.
[0004] The traditional pressure cabin structure usually has only one fixed cabin, and the single-layer structure has high strength requirements. When achieving high pressure or high negative pressure, the structure may be damaged, deformed, or even exploded due to the structural strength bearing capacity, and it is impossible to simulate harsh environments such as high pressure or high negative pressure. Therefore, it cannot meet the needs of research, testing, or adaptive training of personnel in special environments. Therefore, a pressure cabin structure with multiple cabins that can achieve high pressure or high negative pressure simulation environment and gradually increase or decrease pressure is needed to simulate harsh pressure environments.

The temperature sensor 23, the pressure sensor 24 and the humidity sensor 25 can monitor the temperature, pressure and humidity in the cabin 2 in real time, so that the staff can accurately control the temperature, pressure and humidity in the cabin 2 through the electrical control cabinet 15, thereby truly simulating the temperature, pressure and humidity values in different geographical environments, so that the trainees can conduct adaptability training in the corresponding environment.
[0034] In this embodiment, in order to reduce the probability of danger caused by lack of oxygen to the trainees in the cabin 2, an oxygen concentration sensor (not shown in the figure) is also provided in the cabin 2 to monitor the oxygen concentration in each cabin 2 in real time. In addition, a high-pressure oxygen cylinder 32 can be fixed on the base 1, and an oxygen mask (not shown in the figure) connected to the high-pressure oxygen cylinder is arranged in each cabin 2, so as to supply oxygen in time when the trainees feel lack of oxygen, thereby improving safety.
