Normal-pressure low-oxygen pre-acclimatization method and system

Abstract

The invention provides a normal-pressure low-oxygen pre-acclimatization method and system. The method comprises the steps of: placing a plurality of training bicycles in a cabin body, providing nitrogen and oxygen into the cabin body, and monitoring the oxygen concentration and carbon dioxide concentration in the cabin body, and the heart rate and blood oxygen saturation of trainees; subjecting nitrogen and oxygen input in the training environment to coarse adjustment and fine adjustment in a segmented control mode, and increasing or reducing the simulated altitude to a certain range at the fastest speed through experience control. PD control is used in the large time delay stage to enable the current height to approach the target height at the gradually-reduced change rate, fuzzy control is adopted in the system balance stage, and therefore control over the oxygen concentration in the cabin is rapidly and accurately achieved.

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
