A method and system for pre-acclimation training in normal pressure and hypoxia

Abstract

The invention provides a normal-pressure hypoxic pre-accustoming training method and system. A number of training bicycles are placed in the cabin, nitrogen and oxygen are provided to the cabin, and the oxygen concentration and carbon dioxide concentration in the cabin are adjusted to train personnel's heart rate and blood oxygen. The saturation is monitored, and the nitrogen and oxygen input in the training environment are roughly adjusted and fine-tuned by using the segmented control method. Through empirical control, the simulated altitude can be raised or lowered to a certain range at the fastest speed. In the hysteresis stage, the PD control is used to make the current altitude approach the target altitude with a gradually decreasing rate of change, and the fuzzy control is used in the system balance stage, so as to quickly and accurately realize the control of the oxygen concentration in the cabin.

Description

technical field [0001] The invention relates to the field of plateau environment pre-acclimatization, in particular to a pre-acclimatization training method suitable for people who rapidly enter plateau areas from plain areas. Background technique [0002] The low-oxygen environment on the plateau will directly affect the life and health of people who are rapidly entering the plateau, and bring about a series of problems such as the high incidence of acute altitude sickness and the reduction of continuous operation ability. According to statistics, more than 35.6% of people will experience acute altitude sickness with varying degrees of severity during the rapid advance from the plain to the plateau, manifested as symptoms such as headache, anorexia, vomiting, fatigue, dizziness, and insomnia. It develops into high altitude pulmonary edema or high altitude cerebral edema, which is life-threatening. Plateau medical research shows that slow step intermittent hypoxic compound ...

AI Technical Summary

Problems solved by technology

[0005] (1) Simulation methods are not used for pre-design. Generally, physical objects are built directly, and relatively optimal structural design cannot be achieved, and the simulation effect cannot be guaranteed.

[0006] (2) It is designed with air compressors, nitrogen generators, masks and other components. The structure is relatively complicated, the volume is large, the weight is heavy, and the use and maintenance costs are relatively high. It is suitable for targeted pilot training with a small number of people, but not for A large number of personnel training, can not be mobile and mobile use

[0007] (3) There is no linkage design between the physiological condition of the personnel and the safety equipment, and the personal safety of the training personnel in the cabin cannot be effectively guaranteed

[0008] (4) The segmented control method of empirical control, PD control and fuzzy control is not used, and it is divided into two-stage control of coarse adjustment and fine adjustment at most, which makes the realization time of simulating the low oxygen concentration environment longer, generally more than half an hour, The system only takes 20 minutes
