Embodiment 1

[0072] Such as figure 1 As shown, a kind of sleep EEG monitoring method provided by the present invention comprises the following steps:

[0073] 1) The EEG acquisition data module collects multiple sleep EEG signals X of the monitored person in a single channel, and transmits them to the main control module communicating with the EEG acquisition data module, and the hardware interaction module of the main control module receives the EEG acquisition data module The sleep EEG signal is passed to the signal processing and modeling module; the single-channel EEG signal is the Pz-Oz channel EEG signal;

[0074] 2) The signal processing and modeling module performs empirical mode decomposition on multiple sleep EEG signals X, adds a low-order random noise to each input sleep EEG signal X, and analyzes each sleep EEG signal X through the empirical mode decomposition algorithm. The electrical signal X is decomposed for I repeated iterations to obtain an intrinsic mode function of em...

Abstract

The invention provides a sleep electroencephalogram monitoring method and system. The method is a single-channel computer sleep scoring algorithm based on data driving. First, collected decomposed electroencephalogram signal segments are decomposed using an empirical mode. Then, the features are extracted based on a statistical model from the obtained fixed mode function, and statistical analysis is performed to determine the validity of the selected feature. Finally, the automatic sleep segmentation is carried out by adopting a random undersampling classification algorithm. According to the sleep electroencephalogram monitoring method and system provided by the invention, weak classifier learning classification is performed by combining empirical mode decomposition algorithm iteration and random undersampling, and the problem of class imbalance of sleep electroencephalogram analysis can be reduced while the adaptivity of the collected sleep electroencephalogram signals can be improved.

Description

technical field [0001] The invention belongs to the technical field of sleep monitoring, and in particular relates to a sleep EEG detection method and system. Background technique [0002] We spend about a third of our lives sleeping, so we have a vague idea of ​​sleep, but that doesn't mean sleep pathology is simple. Sleep is extremely important to human health. Many sleep-related diseases, such as sleep apnea, insomnia and narcolepsy, have seriously affected people's quality of life. Recent studies have shown that people are now sleeping less than in the past, and sleep quality has also declined. Sleep / circadian rhythm disturbances may be an important sign of neurodegenerative diseases such as Alzheimer's disease and Parkinson's disease. The treatment of sleep pathology Can improve the quality of life of patients. [0003] At present, sleep monitoring equipment and instruments at home and abroad are mainly used to distinguish various states of sleep, measure and analyze ...
