Digital simulator for AMS risk assessment

Abstract

The invention discloses a digital simulator for AMS risk assessment. The digital simulator comprises a crowd simulation module, a measurement interference simulation module and an AMS risk assessment module. The crowd simulation module is used for creating simulation crowds with different hypoxia tolerance capacities by applying a mathematical model of a human hypoxia stress system and a plurality of instance experiment data. the measurement interference simulation module is used for simulating measurement interference and deep respiration physiological interference in the SpO2 information, and superposing simulated interference signals onto the SpO2 generation curve of the simulated crowd; and the AMS risk assessment module obtains indexes used for assessing AMS risks, and the indexes are designed based on parameters of the identified model and used for representing the real hypoxia adaptability of different virtual crowds. According to the AMS risk assessment method, richer research data can be obtained for AMS risk assessment algorithm research, and effective and reliable AMS risk assessment is realized.

Description

technical field [0001] The invention belongs to the technical field of acute mountain sickness testing and evaluation, and in particular relates to a digital simulator for AMS risk evaluation. Background technique [0002] When rapidly ascending to a plateau area with an altitude of about 2,500 meters or above, some people may develop discomfort symptoms including headache, nausea, vomiting, and insomnia. This series of manifestations is collectively referred to as acute mountain sickness (AMS). The reason for this phenomenon is the low oxygen concentration and atmospheric pressure in the plateau environment, which makes it difficult for people to live a normal and healthy life in the plateau area. [0003] In order to ascertain the relationship between the adaptability of the human body under plateau hypoxia and various factors, many scholars have studied blood oxygen saturation (SpO 2 ), heart rate, blood pressure and other physiological factors have been extensively stud...

AI Technical Summary

Problems solved by technology

In the plateau environment, the subjects will suffer a lot of physical pain, and the severe ones face life-threatening, and the experiment needs to consume a lot of manpower and material resources, and the high cost makes it difficult to continue the research; on the other hand, the algorithm design of AMS risk assessment A large amount of data support is required to ensure its high accuracy. Due to the limitation of objective conditions, this experiment cannot be carried out on a large scale, making it difficult to obtain data
