Hardware Design On System Of Brainwave Therapeutic Instrument

This thesis proposes a new induction method of Brainwave Entrainment which combines the traditional acupuncture with rhythmic acousto-optic stimulation, studies the therapeutic mechanism of acousto-optic stimulation and low-frequency electrical pulse stimulation, and determines the design parameters of the therapeutic Instrument. And then we design the intelligent Brainwave Therapeutic Instrument system based on the above study.In this thesis, we mainly design the hardware circuit of the intelligent Brainwave Therapeutic Instrument system, which includes parameters of the therapeutic Instrument, scheme decision, hardware design, the reliability design of the system and the system debugging combined with the software design.After referring to many references, the thesis proposes a new method of Brainwave Entrainment audio waveform synthesis combined with the current ways, which modulates the amplitude of the carrier by the use of treatment sine-wave frequency to generate amplitude modulation signals, controls them with analog switches, and then acquires the dual-channel audio signal by the use of filter circuit.In the design of boost circuit, we innovate select the reverse pulse transformer step-up manner which not only achieves the purpose of pulse step-up but also the electrical isolation of input and output circuits. By this way, we can ensure the treatment of electrode is safe for human.Software debugging combined with the hardware circuit proves that this plan is practical and feasible, has achieved the anticipated project objective, provided a good solution for the design of brainwave therapeutic instrument.
