Bionic hand control system based on electroencephalogram signals

The invention discloses a bionic hand control system based on electroencephalogram (EEG) signals. Eye closing durations of different lengths are used as different control signals. The system specifically comprises an EEG signal acquisition module, an EEG signal processing module, a central processing unit, a man-machine operation module, a physical model building module, a transfer node module, and an acoustic control revision module. According to the invention, by taking eye closing durations of different lengths as different control signals, the system is easy to use; and meanwhile, animation simulation is performed on each command before each command is executed, so the system is safer in use and more precise in control.
