[0017] The training cabin 1 is a pressure vessel with internal pressure and external reinforcement, with an overall size of 30 meters × 20 meters, a diameter of 2.8 meters, and a runway width of 1.6 meters. The simulated altitude is about 8,000 meters above ground level, and the temperature is 18°C ​​to 28°C. It is equipped with air conditioning, lighting, cameras, intercoms, object delivery tubes, dumbbells, pullers, folding seats, movable targets, movable obstacles, etc., and can simultaneously meet the needs of 1 to 30 people to conduct long-distance running endurance training, equipment physical training, crawling, crossing obstacles, simulated mobile shooting and other subject training and experience in a low-pressure and low-oxygen environment on the plateau. The training cabin 1 is a simulated workspace used by various detection or test equipment. In order to facilitate the entry and exit of personnel, various instruments and equipment, and the observation and monitoring of various test conditions during the test and detection process, it is also equipped with an observation window 2, a sanitary cabin 4, a transition cabin 5 and a cabin door 6.

[0018] The transition cabin 5 is the connecting part of the training cabin 1. It is formed and welded into a rectangular box-shaped structure with metal plates, and the surface is welded into a "T"-shaped reinforcing rib plate with metal plates. This structure can facilitate the entry and exit of people in the training cabin 1 without affecting the training of other people in the training cabin 1.

[0019] The observation window 2 is installed in front of the training cabin 1, wherein the observation window seat of the observation window 2 is fixedly connected by welding, the mirror glass of the observation window 2 is fixedly installed by screws using a metal pressure plate, and a sealing strip is installed between the mirror glass and the observation window seat for sealing; the mirror glass is made of high-strength ultra-white glass, with a clear field of view, high strength, and a safety factor of more than 10 times, so that the staff can clearly understand and observe the situation of the trainees through the observation window 2.

[0020] The hatch 6 is arranged on the transition cabin 5 and adopts a self-developed quick-opening thin-shell door, which has the characteristics of light weight, high strength, and easy operation; at the same time, the hatch 6 is installed on the door frame through hinges, and a sealing strip is installed between the hatch 6 and the door frame for sealing. The door frame is formed and processed by metal plates and welded and fixed in front of the transition cabin 5. When working, the hatch 6 has a micro-pressure self-closing function.

[0021] The sanitary cabin 4 is connected to the training cabin 1 and the transition cabin 5, so that people in the training cabin 1 can enter the sanitary cabin 4 through the transition cabin 5, and enter other cabins through the cabin door under the same pressure conditions without affecting the work between the systems.

[0022] The saddle 3 is arranged outside the training cabin 1 and is designed with reference to relevant standards for pressure vessel supports. It is welded and processed by metal plates and is used to support and fix the training cabin 1. It is a supporting device for supporting and fixing the training cabin 1.

[0023] The novel conventional training cabin for plateau environment described in the present invention also includes a pressure control system and a temperature and humidity control system for adjusting the training cabin body 1 and the transition cabin 5 .

[0024] like Figure 2 As shown, the pressure control system includes a variable frequency vacuum unit 7 connected to an external pressure storage container, through which the variable frequency vacuum unit 7 can be used to adjust the pressure in the training cabin 1 and the transition cabin 5 to reach the atmospheric pressure equivalent to the corresponding altitude, so as to achieve the purpose of training. The variable frequency vacuum unit 7 is connected to the air conditioning devices in the training cabin 1 and the transition cabin 5 through a pipeline through a stop valve 8, a regulating valve 9, a bypass regulating valve 10, a main regulating valve 11 and a solenoid valve 12, respectively, so that the pressure in the training cabin 1 and the transition cabin 5 can be adjusted by an external pressure device.

[0025] like Figure 4As shown, the temperature and humidity control system includes a temperature and wind speed transmitter 13 and a fresh air supply device 18 communicated with an external electric heating device, as well as a control system lower computer 16, a PC 19 and a PLC controller 17. A temperature sensor and a humidity sensor electrically connected to the PLC controller 17 are provided in the training cabin 1 and the transition cabin 5. A circulating air fan 14 and a temperature and humidity adjustment device 15 are also provided in the training cabin 1 and the transition cabin 5. The temperature and wind speed transmitter 13 controls the temperature control system lower computer 16 through the PLC controller 17 under the action of the PC 19, and the temperature and humidity in the training cabin 1 and the transition cabin 5 are adjusted under the action of the circulating air fan 14, the temperature and humidity adjustment device 15 and the fresh air supply device 18.

[0026] like Figure 3 As shown, in the actual application process, a new type of conventional training cabin for plateau environment described in the present invention is used. First, according to the test requirements, the speed and pressure height that the training cabin 1 needs to be preset before the test are calculated, the pressure cabin door 6 and other channels communicating with the outside are closed, and the variable frequency vacuum unit 7 is started through the automatic control system to preset the pressure in the training cabin 1 to the required pressure height. Then, according to the test requirements, the adjustment of the rising or falling speed is determined, the opening size of the regulating valve 9 is calculated through the control system, the regulating valve 9 is adjusted to the corresponding opening in advance, and the variable frequency vacuum unit 7 is started. At the same time, the PLC controller 17 fine-tunes the variable frequency vacuum unit 7 and each regulating valve 9 according to the collected data information through the PID control system operation to achieve the target rising rate and control the rising rate accuracy. Finally, check and confirm whether each link meets the test requirements, check whether the pressure in the training cabin 1 meets the test requirements, if not, start the variable frequency vacuum unit 7 through the automatic control system to make its pressure reach the required pressure for the test. The temperature and humidity control is achieved by measuring the cabin temperature value through the temperature sensors and humidity sensors installed in the training cabin 1 and the transition cabin 5, and controlling the temperature control system lower computer 16 through the PLC controller 17. The temperature and humidity in the training cabin 1 and the transition cabin 5 are regulated under the action of the circulating air fan 14, the temperature and humidity regulating device 15 and the fresh air supply device 18. In a high temperature environment, the PID control system control method is used to control the start and stop of the electric heating equipment to adjust the cabin temperature. In a low temperature environment, in order to ensure the stability and reliability of low temperature control, a two-stage cooling control method is adopted. First, the temperature and wind speed transmitter 13 is used to perform the first-stage cooling, drying and dehumidification. At the same time, the fresh air supply device 18 can also send fresh air into the cabin for circulation, and perform the second-stage precise cooling control.

Through the organic combination of each system, a single environment simulation of altitude, temperature, and humidity or a simulation of any combination of the three environments can be achieved, so that users can train in the plateau environment and can quickly adapt to the plateau environment. In addition, the probability of altitude sickness is reduced during the training process, which is conducive to the training personnel to carry out conventional training in the real environment.
