Abstract

The invention relates to a low-pressure adjusting system for a flight simulation cabin, belongs to the technical field of simulation cabins, considers the tiny influence of the number of trainees on environment indexes and the training duration factor, and achieves the low-pressure adjustment of the environment indexes through the adaptive cooperation of a low-pressure adjusting device, an environment index adjusting device, a human body detection device and a timing device. The flight simulation cabin can be comprehensively and carefully monitored and adjusted, and the reliability and accuracy of low-pressure simulation of the flight simulation cabin are guaranteed. By detecting the number of training people and the training duration in real time, the corresponding low-pressure adjusting quantity and the corresponding environment index adjusting quantity are mapped, and then the low-pressure adjusting device and the environment index adjusting device are controlled, so that feedback dynamic adjustment aiming at the tiny influence of the'training people number and training duration 'flight simulation cabin is realized; compared with related equipment and facilities adopting long-time low-voltage detection and environmental index detection, the cost of the scheme is reduced by exponential multiples, and the scheme is suitable for popularization and application in scientific research laboratories.

Description

technical field [0001] The invention belongs to the technical field of simulation cabins, and in particular relates to a low-pressure regulation system for a flight simulation cabin. Background technique [0002] A low-pressure chamber is a ground device that artificially simulates high-altitude environments such as low pressure and hypoxia. Low-pressure chambers have many uses, mainly in the fields of aerospace, basic research, medical treatment, sports training and altitude adaptation. The chamber that is not completely airtight relies on the air extraction device to create a low-pressure hypoxia state in the cabin, and can be adjusted to a simulated "high-altitude" air pressure of several kilometers or 10,000 meters as needed. [0003] In the existing flight simulation cabin, through the cooperation of the air extraction system and the fresh air system, the low pressure adjustment in the flight simulation cabin can be realized, and the simulation of the oxygen index, car...

Problems solved by technology

[0003] In the existing flight simulation cabin, through the cooperation of the exhaust system and the fresh air system, the low pressure adjustment in the flight simulation cabin can be realized, and the simulation of the oxygen index, carbon dioxide index, and temperature and humidity index can also be used to realize the simulation of the environmental indicators in the flight simulation cabin; However, the slight impact of the number of trainers (relevant staff) (different numbers are simulated with the same environmental indicators) on the oxygen index, carbon dioxide index, and temperature and humidity index is ignored. If the corresponding time is long enough, it may affect the accuracy of low pressure simulation. As a result, the low-pressure environment simulation fails. At this stage, there is a lack of adaptive monitoring and adjustment for the number of trainees and the corresponding training time.
