Embodiment Construction

[0088] Such as figure 1 A kind of fatigue driving EEG monitoring method based on the degree of meditation and concentration is shown, comprising the following steps:

[0089] 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;

[0090] 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 con...

Abstract

The invention discloses a fatigue driving electroencephalogram monitoring method based on the degree of meditation and the degree of concentration. The method includes the steps of 1, brain wave signal acquisition, wherein a brain electrical signal acquisition device is adopted to acquire and preprocess brain wave signals of a driver and synchronously transmit the brainwave signals to a brain electrical signal monitoring device; 2, brain wave signal analysis and processing, wherein analysis and processing are conducted on the brain wave signals acquired and preprocessed by the brain electrical signal acquisition device each second according to the sequence of sampling time, and whether the driver is in the fatigue state or not is judged; the brain electrical wave signals acquired and preprocessed in any second are analyzed and processed in the following steps of synchronous brain electrical wave storage, meditation degree and concentration degree extraction, fatigue degree calculation, threshold value comparison, driver fatigue degree calculation in continuous K seconds and fatigue driving judgment. The fatigue driving electroencephalogram monitoring method is simple in steps, reasonable in design, convenient to implement, good in use effect and capable of accurately monitoring the fatigue driving state of the driver easily, conveniently and fast.

Description

technical field [0001] The invention belongs to the technical field of brain wave monitoring, and in particular relates to a fatigue driving brain wave monitoring method based on meditation degree and concentration degree. 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 include el...
