Interface system of human brain and manipulator in micro-power wireless communication mode

The invention relates to an interface system of a human brain and a manipulator in a micro-power wireless communication mode, which belongs to the intercrossed field of biomedical engineering and mechanical electronic engineering. The interface system comprises a signal acquisition device, a signal analysis module finished by a computer, and a wireless communication module, wherein the signal acquisition device acquires electroencephalogram signals; the electroencephalogram signals enter the computer, and the signal analysis module adopts power spectrum density analysis to detect the power spectrum densities of frequency points A, B and C of the electroencephalogram signals; the frequencies of the three points A, B and C are between 2 and 30 Hz; when the power spectrum densities of the frequency points is between 2 and 50 microvolts, the characteristic information of the frequency points is 1, otherwise, the characteristic information of the frequency points is 0; and the electroencephalogram signals form the characteristic information consisting of three binary numeral values, and the characteristic information is sent to the manipulator through the wireless communication module.The interface system adopts a multi-channel electroencephalogram data acquisition mode, a wireless mode can better solve the problem, and the interface system is convenient for a user to wear.
