介绍了应用8031单片机开发的双闭环脑电反馈控制仪的硬、软件设计,脑电噪声干扰的抑制,并给出了两个脑电反馈控制目标函数。该仪器将脑电生物反馈和以脑电主峰频率调制的微弱磁信号的反馈控制有机结合,对脑电调节更加有效,具有临床应用和科学研究价值。
The hardware and software design of dual closed-loop EEG feedback controller developed by using 8031 MCU and the suppression of EEG noise interference are introduced. And two EEG feedback control objective functions are given. The device organically combines the electroencephalogram biofeedback and the feedback control of the weak magnetic signal modulated by the frequency of the main peak of the electroencephalogram, which is more effective for electroencephalogram adjustment and has clinical application and scientific research value.
