- Abstract:
- To intelligently identify the physiological state of vigilance workers with low awakening and low attention, this paper presents a monitoring and awakening system for low arousal/vigilance state based on the field-programmable gate array (FPGA) and electroencephalogram (EEG) signals processing. The system collects EEG signals from the scalp, converts the analog signals to digital signals, and then uses Fourier transform to calculate its power spectrum. The system subsequently acquires four eigenvectors-the relative energies of the θ and α, the gravity frequency, and the spectrum entropy-which are used to characterize the low arousal state, and on this basis, the support vector machine (SVM) is used to recognize the low arousal state. Once the low arousal state is identified, the SVM will awaken the vigilance worker using a sound alarm module. The system can effectively distinguish the low awakening state, and the recognition rate reaches 90.8%. Moreover, it can provide a wearable intelligent equipment to improve performance of vigilance operations.
