Embodiment Construction
[0029] The present invention will be further described below in conjunction with accompanying drawing:
[0030] combine figure 1 , fatigue detection includes the following steps:
[0031] Step 1: Use the Bluetooth acquisition device, ECG sensor, and synchronously collect EEG signals, blink information and ECG signals.
[0032] The EEG signal and blink information collection equipment is a Bluetooth EEG headset. One input end of the headset is connected to the EEG sensor on the user's forehead, and the other input end is connected to the user's ear electrode, and the brain wave voltage changes of the user's FP1 and A1 channels are obtained through the dry electrode, and are amplified and filtered internally. Output the digital signal reflecting the EEG intensity to the EEG signal analysis module through Bluetooth. The sampling frequency is 512Hz, and the baud rate is 115200bps.
[0033] The ECG signal acquisition module is an ECG acquisition circuit based on the BMD101 chip...
