The invention provides a brachial
plexus and
exoskeleton cooperative control method and
system based on a brain-computer interface, and relates to the field of
intelligent control. The method comprises the steps that electroencephalogram signals and
upper limb electromyographic signals of a target object during
motor imagery are collected; predicting the motion intention of the target object through a neural network based on the electroencephalogram signals and the
upper limb electromyographic signals; based on the motion intention, determining a target brachial
plexus branch according to a preset motion intention and brachial
plexus mapping rule; generating a
nerve stimulation control instruction and an
exoskeleton cooperative control instruction based on the target brachial plexus
branch and the motion intention; and according to the
nerve stimulation control instruction, performing electrical stimulation on the target brachial plexus
branch to drive the corresponding
muscle to contract, and meanwhile, according to the
exoskeleton cooperative control instruction, controlling the
upper limb exoskeleton to apply assistance to the corresponding joint. The method and the device are used in the cooperative control process of the brachial plexus and the exoskeleton, and the technical problem of inaccurate control in the existing limb control process based on neural signals is solved.
