[0038] The emergency oxygen supply system 6 is used to meet the oxygen inhalation and health care needs of personnel; the emergency oxygen supply system adopts a medical oxygen cylinder, and after reducing the pressure to a breathable pressure, it provides an oxygen source to the cabin 1 through a degreased copper tube. The cabin 1 is equipped with a humidified bottle-type nasal oxygen supply device to meet the oxygen inhalation and health care needs of personnel.

[0039] The integrated automatic control system 7 is used to monitor and automatically adjust the gas concentration, pressure, equipment operation status, and experimental status in the cabin; the integrated automatic control system 7 is electrically connected to and controls the electrical equipment in the fresh air system 2, the positive pressure system 3, the low pressure system 4, the temperature and humidity control system 5, the emergency oxygen supply system 6, the safety monitoring system 12, and the physiological monitoring system 13.

The integrated automatic control system 7 is secondary developed and compiled using Siemens SIMATIC S7-1500 series PLC as the core, and is integrated and installed in the integrated control console. It can monitor, display and control the altitude, temperature, humidity and other index parameters in the cabin 1 according to the set requirements; it has the functions of monitoring and automatic adjustment of the gas concentration, pressure, equipment operation status, cabin experiment status, etc., and has the function of fault alarm prompt; it is simple to operate and the picture is clear.

[0042] Experimental operation:

[0043] Before the operation of the high and low pressure comprehensive simulation experiment cabin in complex environment of plateau cold areas, the status of all cabin doors 10, observation windows 11, monitoring components, valves, etc. should be checked to confirm the safety status of the system.

[0044] After the experimenter enters the cabin 1, the operator confirms that there is no abnormality, closes the cabin door 10, and then operates the entire experiment process on the integrated operation panel.

[0045] When the experimental cabin is conducting a positive pressure working experiment, the positive pressure system 3 is operated, the air compressor is started to fill the air tank, and the supporting control regulating valve is controlled to provide compressed air of a certain pressure into the cabin 1, so as to realize the pressure control from the local altitude to the sea level. At the same time, the "oxygen intoxication" research from the transition from plateau to plain can be realized.

[0046] When the experimental cabin conducts a low-pressure working experiment, the low-pressure system 4 is operated, the vacuum pump is started, the pressure is buffered by the buffer tank, and then the supporting control regulating valve is started to provide pressure to decompress the cabin 1, thereby achieving pressure control from the local altitude to an altitude of 10,000 meters.

[0047] When the experimental cabin is conducting a low temperature experiment, the temperature and humidity control system 5 is operated, the refrigeration unit is started, and then the control regulating valve, signal feedback device, etc. are started to achieve adjustable and controllable temperature of -50℃~+80℃.

[0048] When the experimental chamber is conducting a high-temperature working condition experiment, the temperature and humidity control system 5 is operated, the heating unit is started, and then the control regulating valve, signal feedback device, etc. are started to achieve an adjustable and controllable humidity of 20%RH~95%RH when the temperature is not lower than 15℃.

[0049] When emergency support or health care is required during the experiment, the valve of the medical oxygen cylinder of the emergency oxygen supply system is manually opened, and after the pressure is reduced to a breathable pressure (usually not higher than 0.5MPa), the copper tube supplies oxygen to cabin 1. Cabin 1 is equipped with a humidified bottle-type nasal oxygen supply device to meet the oxygen needs of personnel at various experimental stations in cabin 1.

[0050] The experimental cabin adopts automatic control and mechanical manual control, which are concentrated in an integrated automatic control system 7, and the system is regulated by controlling the regulating valves, signal feedback devices, and various detection components of each system.

[0051] The safety monitoring system 12 installed in the experimental cabin monitors the gas concentration and pressure in the cabin 1 in real time and dynamically through multi-parameter sensors such as oxygen concentration, carbon monoxide concentration, carbon dioxide concentration, and pressure. It has the function of automatic adjustment and alarm when exceeding the limit. When the value exceeds the limit, it will send out an audible and visual alarm signal, and feedback to the automatic control program to start fresh air compensation replacement, providing reliable guarantee for the safe operation of the system.

[0052] The physiological monitoring system 13 installed in the experimental cabin can dynamically monitor the physiological parameters such as electrocardiogram, blood pressure, blood oxygen saturation, body temperature, pulse rate, etc. of the people in the cabin, and transmit the signal to the control system through the cabin for feedback, recording, reference and copying.

[0053] The experimental cabin is equipped with a fresh air system 2. When the gas monitoring sends out an audible and visual alarm indicating that the indicators exceed the standard during the experiment, the system will transport the air purified from oil, water, PM2.5, etc. outside the cabin into the cabin 1 to maintain the air quality in the cabin 1 and achieve the internal environmental conditions required for the experiment, thereby ensuring the simulation authenticity of the experimental state. Example 2

[0054] The difference between this embodiment and embodiment 1 is that:

[0055] In order not to interrupt the experimental process, a sewage system is installed in the cabin to meet the physiological and hygienic needs of personnel; a delivery cylinder with inner and outer doors is installed on the cabin to realize the delivery of objects under the experimental state.

[0056] The sewage discharge system includes a sewage tank, a check valve, a signal controller, etc. Sewage and dirt enter the sewage tank through a pipe with a check valve (single inlet and single outlet). The signal controller is used to monitor the liquid level of the sewage tank. After the liquid level exceeds the limit, the sewage tank sewage valve is automatically opened to control the liquid level. During the experiment, the experimenters can meet their physiological and hygienic needs during the experiment, and clean non-solid excrement is collected in the sewage tank and automatically discharged when the liquid level is reached, thereby ensuring the consistency of the experimental process and meeting the purpose of long-term experiments; ensuring that the experiment will not be terminated accidentally due to the physiological and hygienic needs of the personnel during the experiment, thereby meeting the purpose of long-term experiments.

[0057] The object delivery tube is arranged on the cabin body, and has doors inside and outside to realize the object delivery in the experimental state, ensuring that the experiment will not be terminated accidentally due to insufficient preparation of experimental equipment during the experiment. Example 3

[0058] The difference between this embodiment and embodiment 1 or embodiment 2 is that:

[0059] Emergency stop buttons and resume buttons are set inside and outside the cabin. If there is an emergency during the experiment, personnel inside and outside the cabin can click the emergency stop button to keep the current experimental status unchanged. After the problem is solved and it is confirmed that the experiment can be resumed, click the resume button to continue to ensure the normal progress of the experiment.
