Fatigue driving electroencephalogram monitoring method based on multi-threshold comparison

Abstract

The invention discloses a fatigue driving electroencephalogram monitoring method based on multi-threshold comparison. The fatigue driving electroencephalogram monitoring method comprises the following steps of step 1, acquiring an electroencephalogram signal: acquiring and pre-treating the electroencephalogram signal of a driver by using an electroencephalogram signal acquiring device, and synchronously transmitting the electroencephalogram signal to an electroencephalogram signal monitoring device; step 2, carrying out analysis treatment on the electroencephalogram signal: carrying out the analysis treatment on the electroencephalogram signal which is acquired and pre-treated by the electroencephalogram signal acquiring device within each second according to the sequence of sampling time, and judging whether the driver is at a fatigue driving state or not at the moment according to an analysis treatment result. The process of carrying out the analysis treatment on the electroencephalogram signal which is acquired and pre-treated within any second comprises the following steps: synchronously storing the electroencephalogram signal, extracting a characteristic signal, determining a characteristic quantity, carrying out the multi-threshold comparison and judging the fatigue driving. The method disclosed by the invention has simple steps, a reasonable design, is convenient to realize and has good use effects; the fatigue driving state of the driver can be conveniently, simply, rapidly and accurately monitored.

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...

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.
