Embodiment Construction

[0040] Below, the present invention will be described in further detail in conjunction with the accompanying drawings.

[0041] The invention applies the brain-eye tracking technology to the attitude stabilization control of the space manipulator in the weightless environment. Brain-eye movement control, as a new type of control method, gets rid of the requirements for body movements, breaks through the limitations of relying on astronauts to operate mouse keyboards, joysticks and other traditional manual controls, and eliminates the physical inconvenience caused by the weightlessness of space. Or the input obstacles encountered when interacting with the space manipulator due to reasons such as limited environment, realize two-way multi-mode human-computer interaction, complete the capture of failed satellites by the space manipulator in space, or complete the equipment operation of the space station, and enhance our country’s ability in space. advantages in the field.

Abstract

The invention discloses a multi-mode neural decoding control system and method for on-orbit operation of a space manipulator, which uses Emotiv Epoc+ electroencephalography to collect electroencephalogram signals and oculoelectric signals, and uses a microphone that comes with a computer to collect voice signals; the mode The recognition module fuses and decodes four types of EEG signals and four types of voice signals to identify conscious eye blinking signals; the control module transfers the fusion decoding results of EEG signals and voice signals and conscious eye blinking signals into the built unity environment through UDP network communication, Convert it into a control signal to control the movement of the space manipulator in the virtual environment and grab the target item. Aiming at the weightlessness of astronauts in space, the invention adopts the method of controlling the movement of the space manipulator in the virtual environment through biological information to complete the task of moving the designated target and achieve better human-machine interaction effect.

Description

technical field [0001] The invention relates to human-computer interaction intelligent control technology, in particular to a multi-modal neural decoding control system and method for on-orbit operation of a space manipulator. Background technique [0002] As a space station, a space station is a giant satellite placed in space and fixed in orbit for a long time to carry out various space activities and form a multi-purpose space center. In actual operation, the space station can dock with multiple spacecraft at the same time to form a large orbital complex. The various advantages of the space station are not only used in scientific experiments, but also in the military field. It has unique military application functions. The space robot arm plays a huge role in the normal operation of the space station. [0003] Early space manipulators were controlled through keyboards, buttons, and teaching boxes, and the operations were complex and could only complete simple tasks. In ...
