Brain fatigue detection method with high sensitivity and high electromagnetic interference resistance

The invention discloses a brain fatigue detection method with high sensitivity and high electromagnetic interference resistance, which is characterized in that a testee is stimulated and induced to generate auditory steady-state response evoked potential based on 80Hz Donchirp sound signals, and rhythm signals are analyzed by using a multi-scale entropy MSE-IFV algorithm of instantaneous frequency, so that corticoelectroencephalogram signals in brain fatigue and normal waking states are successfully distinguished, and the detection accuracy is improved. And compared with Alpha waves and full waves analyzed by using the same algorithm, the Alpha waves and the full waves have higher sensitivity and anti-interference capability. A method with high interference resistance and high sensitivity is provided for brain fatigue state detection, and the method is suitable for brain fatigue detection in a complex environment. 本发明公开了一种高灵敏度、高抗电磁干扰的脑疲劳检测方法，基于80HzDonchirp声音信号刺激诱发被试者产生听觉稳态反应诱发电位，并利用瞬时频率的多尺度熵MSE-IFV算法对此节律信号进行分
