System and method for detecting and relieving driving fatigue based on electrical acupoint stimulation

Abstract

The invention discloses a system and a method for detecting and relieving driving fatigue based on electrical acupoint stimulation. The system comprises an electroencephalogram acquisition device, an upper computer, a lower computer and an electrical stimulation instrument, an input end of the electroencephalogram acquisition device is connected to the cerebral cortex of a driver, an output end of the electroencephalogram acquisition device is connected with the upper computer which is connected with the lower computer, the lower computer is connected with an input end of the electrical stimulation instrument, and a pulse output end of the electrical stimulation instrument is connected to a meridian point, capable of reliving brain fatigue, of the driver through an electrode. The method includes: acquiring electroencephalogram signals of the driver in real time; and extracting fast-wave and low-wave frequency band signals in the electroencephalogram signals, computing a ratio of fast-wave average power spectra to low-wave average power spectra, judging the driving state of the driver according to reduction of the ratio, and controlling the electrical stimulation instrument to start and enter a corresponding working mode. Driving states of the driver are monitored in real time, and electrical stimulation is performed to the driver in good time, so that driving fatigue is relieved better, driving safety is improved, and hidden danger of traffic caused by fatigue driving is reduced.

Description

Technical field [0001] The invention relates to the technical fields of biomedical engineering and mechatronics engineering, in particular to a system and method for detecting and relieving driving fatigue based on electrical stimulation of acupoints. Background technique [0002] In the past ten years, with the rapid increase in the number of cars, traffic accidents have also increased. According to relevant reports, my country has become one of the countries with frequent traffic accidents. There are many factors that cause traffic accidents, among them, driver fatigue driving is the main cause of traffic accidents. In foreign countries, the situation is also very serious. The National Sleep Foundation of the United States issued a press announcement on November 4, 2009, stating that nearly 2 million car accidents are caused by fatigue driving in the country every year. The French National Police Agency's accident report indicated that accidents caused by driving fatigue accou...

Problems solved by technology

The disadvantage of this device is that the early warning of driver fatigue is late, and when the driver's eyes stop opening and closing, it is already in the sleep period, which is quite unfavorable for driving. For the driver to drive safely, early warning must be done.

[0006] In addition, none of the above-mentioned achievements can realize the driver fatigue driving relief function.
