AI Technical Summary

Problems solved by technology

The traditional subcutaneous brainwave acquisition method is complex and inconvenient, so it is difficult to extend it to other fields
At present, the brain-computer interface technology in China is in its infancy, and there are still relatively few related studies.

Embodiment Construction

[0181] Such as figure 1 Shown a kind of fatigue driving EEG monitoring method based on multi-threshold comparison, comprising the following steps:

[0182] Step 1. Brain wave signal collection: use the brain wave signal acquisition device 1 to collect and preprocess the driver's brain wave signal according to the preset sampling frequency, and transmit the preprocessed brain wave signal to the brain wave signal synchronously. Signal monitoring device 2, see figure 2 ;

[0183] The EEG signal acquisition device 1 communicates with the EEG signal monitoring device 2 in a wireless communication mode; the EEG signal acquisition device 1 is a TGAM module, and the TGAM module includes extracting the driver's EEG signal The EEG signal extraction device 1-1 and the EEG signal preprocessing device 1-2 for sampling and preprocessing the signals extracted by the EEG signal extraction device 1-1, the EEG signal preprocessing device 1-2 and The EEG signal extraction device 1-1 is conne...

Abstract

The invention discloses a fatigue driving EEG monitoring method based on multi-threshold comparison. The electric wave signal is synchronously transmitted to the EEG signal monitoring device; Step 2, EEG signal analysis and processing: analyze and process the EEG signal collected and preprocessed by the EEG signal acquisition device per second according to the order of sampling time, and according to The analysis and processing results determine whether the driver is in a fatigue driving state at this time; when analyzing and processing the brain wave signals collected and preprocessed within any second, the process is as follows: synchronous storage of brain wave signals, feature signal extraction and feature quantity determination, multi-threshold comparison and fatigue driving judgment. The method of the invention has the advantages of simple steps, reasonable design, convenient implementation and good use effect, and can accurately monitor the driver's fatigue driving state simply and quickly.

Description

technical field [0001] The invention belongs to the technical field of electroencephalogram monitoring, and in particular relates to an electroencephalogram monitoring method for fatigue driving based on multi-threshold comparison. Background technique [0002] In recent years, with the increase of car ownership and the expansion of road construction scale, problems such as traffic accidents have become increasingly prominent. China is the most populous country in the world, and the number of road traffic accident deaths is also the highest in the world, ranking first in the world for several consecutive years. Drivers risking fatigue driving will undoubtedly bring hidden dangers to the safety of themselves and passengers. The research on driving fatigue is divided into two methods: subjective and objective. The subjective research methods include subjective questionnaire, driver self-record, sleep habit questionnaire, and Stanford sleep scale. Objective research methods i...
