Abstract

The invention relates to an in-spaceport-bin navigation analogy method and system based on head-down bed resting. The physiological effect weightless simulation based on head-down bed resting is combined with the visual navigation simulation based on immersion-type virtual reality technology to form the in-spaceport-bin navigation analogy method and system based on the head-down bed resting. The system is composed of a graphic workstation computer (1), a wide-vision-field helmet-type displayer (2), a three-dimensional mouse (3), a head-down experiment bed (4) and human physiological status monitoring equipment (5). The in-spaceport-bin navigation analogy method and system based on the head-down bed resting has the advantages of being good in weightless simulation effect, real in multi-cabin spaceport scene simulation, simple in method and low in price.

Description

technical field [0001] The invention relates to a navigation simulation method and system in a space station cabin based on head-down bed rest. Specifically, it relates to a method of visual effects and physiological effects of astronauts navigating in the space station cabin under weightless conditions under ground conditions, using virtual reality technology and head-down bed rest as the means, in the multi-section space station cabin The invention discloses a method and system for internal equivalent analog navigation, belonging to the fields of aerospace and medicine. Background technique [0002] The multi-chamber space station has a large and complex internal space. Astronauts have a poor sense of direction inside the space station and are prone to navigation obstacles, which may lead to a decrease in the ergonomics and reliability of the entire space station man-machine-environment system. In order to solve Or to improve the in-cabin navigation of space station astro...

[0004] 1. The parabolic flight simulation of the weightless aircraft can form microgravity conditions within a duration of 15-40 seconds. The traditional applications of the weightless aircraft mainly include astronauts' weightless environment experience training, small-scale operation project training and weightless environment tests of small aerospace products. Due to the sustainable time limit of a single weightless simulation, the parabolic flight simulation method of a weightless aircraft is not suitable for space station cabin navigation, which requires a long time to simulate the weightlessness environment;

[0005] 2. The neutral buoyancy simulation method takes people's feeling of movement and force in weightlessness as the simulation target, and is an extremely effective means for astronauts to carry out exercise and operation training in a weightlessness environment. However, this method cannot effectively shield (or weakening) the auxiliary effect of gravity cues on orientation and navigation. In addition, in reality, due to the construction cost and volume limitations of medium-sized buoyancy tanks, it is often difficult to provide astronauts with a navigation experience for the entire space station interior space in this simulated environment ;
