本文介绍了一种基于音乐治疗的人体脑电信号采集和处理系统,该系统可以对人在音乐治疗前后的脑电信号进行采集、处理和分析。系统的检测电极从人的脑部采集信号,通过预处理电路传到单片机控制模块,再采用nRF24L01无线通信模块将采集到的信号传给上位机,上位机程序对脑电信号进行处理、分析、显示。实验表明,系统能够较好的获取人体脑电信号,数据处理结果显示,有音乐刺激时的脑电信号和无音乐刺激时的脑电信号相比,信号幅值增大、复杂度降低。
This article describes a music therapy-based human EEG signal acquisition and processing system that can collect, process and analyze the EEG signals before and after music therapy. The detection electrode of the system collects the signal from the human brain, passes the pre-processing circuit to the singlechip control module, and then uses the nRF24L01 wireless communication module to transmit the collected signal to the upper computer. The upper computer program processes and analyzes the EEG signal, display. Experiments show that the system can better obtain the human brain EEG signals. The data processing results show that the amplitude and the complexity of the EEG signals in the case of music stimulation are higher than those in the case of no EEG stimulation.
