Electroencephalogram-based sleep quality analysis device and method

Abstract

The invention discloses an electroencephalogram-based sleep quality analysis device and method. The problems that the user sleep quality is improved passively, the price is high, inconvenience is brought to use, and the user cannot know the sleep quality of himself / herself or improve the seep quality are solved. The device comprises an electroencephalogram analyzer and a user mobile phone client;the electroencephalogram analyzer comprises an electroencephalogram electrode assembly, an electroencephalogram processing module, an FPGA microcontroller, a Bluetooth module, a helmet and a power supply module; the electroencephalogram electrode assembly is installed on the helmet and connected with the electroencephalogram processing module through a wire, the electroencephalogram processing module is connected with the FPGA microcontroller through a wire, the FPGA microcontroller is connected with the Bluetooth module through an electric wire, the power supply module is connected with the electroencephalogram processing module, the FPGA microcontroller and the Bluetooth module through wires separately, and the electroencephalogram analyzer is connected with the user mobile phone clientthrough wireless communication. The invention further provides the electroencephalogram-based sleep quality analysis method.

Description

technical field [0001] The present invention relates to a method belonging to the field of cognitive neuroscience and information technology, more precisely, the present invention relates to a sleep quality analysis device and method based on electroencephalogram signals. Background technique [0002] With the continuous development of society, people are facing more and more pressure, and people's mental state has been more or less affected. Sleep is the best way to relieve stress and regulate the spirit, and it plays an important role in the repair of human body functions, promotion of human brain memory, reduction of morbidity, and enhancement of immunity. Therefore, people are paying more and more attention to their sleep conditions and Sleep quality. [0003] EEG signals are generated by brain nerve activity and always exist in the central nervous system. The brain-computer interface technology collects sleep EEG signals in the cerebral cortex, which can be used to stu...
