Space walking training device capable of simulating weightlessness conditions through multi-perception

Abstract

The invention discloses a space walking training device capable of simulating weightlessness conditions through multi-perception. According to the device, a multi-perception simulation mode is adoptedto reduce the difference, a real object guardrail provided with low-damping universal wheels and a driven seat are used for simulating the weightless environment of a trainee moving in the plane direction, the motion state of the trainee is tracked in real time through a virtual reality helmet and data gloves worn on the trainee, a position sensor installed on a support structure is used for tracking and positioning the position of the guardrail, the position and motion information is used for positioning the position of the virtual guardrail in the virtual space scene in real time to enablethe virtual guardrail to completely coincide with the real guardrail, and the virtual astronaut in the scene is driven to move, so that in the extravehicular space walking simulation training processof a trainee, besides traditional visual feedback, the multi-channel perception feedback of auditory sense, vestibular sense and force touch sense is achieved at the same time, and therefore the spaceweightlessness state is simulated more realistically.

Description

technical field [0001] The invention relates to the field of space-walking training devices, in particular to a space-walking training device for multi-sensory simulated weightlessness conditions. Background technique [0002] Using virtual reality technology, it is possible to simulate human perception under the condition of weightlessness in space to a certain extent on the ground. By constructing a virtual space scene, astronauts can immerse themselves in the virtual environment to simulate flight missions and interact with the virtual environment. Virtual reality technology has the characteristics of high degree of digitization, high reusability, ability to break through the limitations of the physical environment, and good safety. It has been successfully used by research institutions such as NASA, ESA, and Canada. An important development direction of astronaut training in exploration. [0003] The simulation training of extravehicular activities is an important appli...

Problems solved by technology

Although this training method can simulate the mission process of spacewalking, because it ignores the auditory, vestibular and force-tactile perceptions of people during the actual mission, it only uses visual information to feed back information such as distance, size, and orientation. Judgment of changes in speed and motion state, resulting in a greatly reduced sense of immersion, and it is easy to cause dizziness, nausea and other symptoms caused by inconsistencies between vision, vestibular sense, and force-tactile sense
