Abstract

The invention discloses a brain electricity state detecting method. The brain electricity state detecting method comprises the following steps: acquiring brain electricity signals of a user; converting the brain electricity signals into frequency domain signals from time domain signals to obtain brain electricity frequency domain signals; acquiring feature values of the brain electricity signals according to the brain electricity frequency domain signals and reference values of various frequencies; analyzing the feature values by using a classification model which is established in advance to obtain state types of the brain electricity signals. Correspondingly, the invention further discloses a brain electricity state detecting device. By an embodiment of the invention, accuracy of brain electricity state detection can be improved, and the generalization ability is good.

Description

technical field [0001] The invention relates to the field of electroencephalogram technology, in particular to a method and device for detecting an electroencephalogram state. Background technique [0002] In the prior art, the detection method of the EEG state is generally to use EEG equipment to collect the EEG signal of the user, and then directly extract features from the collected EEG signal, and then analyze the extracted features to obtain the EEG signal. the state you are in. However, this method of directly extracting features is extremely sensitive to noise, which makes the wearing method of EEG equipment more demanding and poor in robustness. Moreover, the accuracy of EEG state detection is greatly affected by individuals and is not suitable for all users. Poor generalization ability. Contents of the invention [0003] Embodiments of the present invention propose a method and device for detecting an EEG state, which can improve the accuracy of EEG state detect...
