A non-contact control method of manned spacecraft based on brain-computer interface

Abstract

The invention discloses a manned spacecraft noncontact operating and control method based on a brain-computer interface. The method is realized through an electroencephalogram signal collector (1), an electroencephalogram amplifier (2), a computer (3), a signal characteristic extraction module (4), a signal characteristic classifying module (5), a display module (6), an output instruction judging module (7) and an instruction output module (8). An astronaut fixes eyes on LED (Light Emitting Diode) instruction keys which flash in different frequencies, the electroencephalogram collection is performed through the electroencephalogram signal collector (1), an electroencephalogram signal is filtered and amplified by the electroencephalogram amplifier (2) and then enters the computer (3), the electroencephalogram signal is identified through the signal characteristic extraction module (4) and the signal characteristic classifying module (5), the identified signal is judged and selected, and a correct instruction is outputted to control a manned spacecraft. According to the method, the remote accurate input of the instruction can be realized, the bottle neck that the astronaut inconveniently operates an instruction bar in a far distance can be broken through, the controllability of the spacecraft can be improved, and the body of the astronaut can be protected.

Description

technical field [0001] The invention relates to a manned spacecraft control method, in particular to a non-contact manned spacecraft control method based on a brain-computer interface. Background technique [0002] Due to the extremely harsh space environment, the overweight feeling brought about by the high acceleration during the ascent phase of the manned spacecraft, and the weightlessness in the space environment, this has brought great inconvenience to the astronauts' command and control. At present, astronauts still control the spacecraft by inputting commands through the command stick or finger touch in the cabin, and the instability of the spacecraft’s operation in space leads to a high rate of misoperation of command input. cause some bodily harm. At present, there is no literature research on the non-contact control method of manned spacecraft at home and abroad. [0003] Brain-computer interface technology is a new type of human-computer interaction, which direc...
