Oxygen concentration adjusting method and system and driving simulation system

Abstract

The invention relates to an oxygen concentration adjusting method and system and a driving simulation system. The oxygen concentration adjusting method comprises the following steps that the altitudeH(B) and the temperature T(B) of a simulated area are set, and the oxygen concentration in the air environment of the simulated area is set to be V(B); real-time detection data P(A) and T(A) of an airpressure detection device and a temperature measurement device in the driving simulation cabin are obtained, and the driving simulation cabin is sealed; regression is carried out according to the actual measurement data of the air pressure and the altitude of different altitude areas to obtain the relation between the air pressure and the altitude, and the preset value V(A) of the oxygen concentration in the simulation bin is calculated in combination with PV / T=C (constant amount); and the V(A) is output to an oxygen concentration control device so that the oxygen concentration control devicecan adjust the oxygen concentration in the driving simulation cabin to be V(A) by filtering oxygen molecules in the air, and the oxygen in the air is separated through an oxygen separation technologyto obtain low-oxygen gas.

Description

technical field [0001] The invention relates to the technical field of traffic safety, in particular to an oxygen concentration adjustment method, system and driving simulation system. Background technique [0002] As early as the 1930s, research on the role of hypoxia has been extensively carried out. In the mid-1950s, researchers from the former Soviet Union proposed that people can adapt to hypoxia in a plateau environment, and the adaptation obtained by training at the same time on the plateau is more conducive to enhancing the human respiratory and cardiovascular system functions, and is beneficial to improving aerobic metabolism. It has a good effect on improving ability and promoting sports performance, especially the performance of endurance events. Since then, plateau hypoxic training has gradually attracted people's attention, and plateau training bases have been established all over the world. Through the investigation of previous international games, it is not ...

AI Technical Summary

Problems solved by technology

The hypobaric chamber is ground experimental equipment for simulating high-altitude environments such as low pressure and hypoxia on the ground. The hypobaric chamber can better simulate the plateau hypoxic environment, but the production cost is high, and parameters such as air pressure, temperature, humidity, and oxygen concentration are difficult to coordinate. It is inconvenient to promote the application

[0005] At home and abroad, there is no precedent for using driving simulators to simulate driving at different altitudes. The research on high-altitude driving simulation at home and abroad is mainly carried out in the actual high-altitude environment, and the paradigm of creating a low-oxygen driving simulation environment has not been considered.
