Driving fatigue produces the imbalance of physiological function and psychological function, and is objectively occurring the phenomenon that driving efficiency declines after referring to the driving of driver's long-time continuous.Driving fatigue can have influence on the attention of driver, sensation, consciousness, thinking, judgement, will, the aspects such as decision and motion.In recent years, road traffic accident generation quantity and death tolls constantly increase, and according to the statistics made by the departments concerned, annual whole world road traffic accident reaches 1,000,000,000 times, and the vehicle accident wherein caused due to fatigue driving accounts for 25-30%.Therefore, research alleviates driving fatigue technology to protection people's life, property safety, improves automobile product competitiveness significant.
Infrasonic wave (0.5-20Hz) due to the natural frequency of its frequency and body very close, such as head is 8-12Hz, and heart is 5Hz, and blood flow frequency is 1.2Hz, be thus easy to cause body produce resonance.The infrasonic wave of suitable intensity acts on body and can improve circulation, QI and blood regulating, enhancing immunity, quickening inflammatory resolution, makes that lax nervous muscle lessens fatigue, pain, discomfort etc.Infrasonic wave based on eegαwave acts on human brain can obviously be affected and the brain electrical acti level of mediator and excited level, bring out the generation of α to greatest extent, create and maintain physiological feedback loop, thus the stress of reduction of patient, get rid of stress, anxiety reduction and depressive emotion, allaying tiredness etc.
At present, less for the technical research of alleviation driving fatigue.There are some researches show and can alleviate driving fatigue to a certain extent by transcutaneous electrostimulation Neiguan acupoint, point Hegu, Laogongxue, Fengchi acupoint, Yongquan acupoint etc.The patent No. is the Chinese patent of CN 104192033A, and disclose a kind of waist support of car seat device alleviating driving fatigue, it has certain help to physical fatigue, but for mental fatigue then DeGrain.The patent No. is the Chinese patent of CN 102988171A, disclose a kind of refrigeration-type driving fatigue canceller, fatigue alleviating is carried out by applying cold stimulation at temple, though the method energy short time fatigue alleviating, but cure the symptoms, not the disease, need at this device of head-mount, some drivers possibly cannot accept, and without fatigue monitoring device.The patent No. is the Chinese patent of CN 103111020A, system and method is alleviated in the detection disclosing a kind of driving fatigue based on electric acupoint stimulation, fatigue alleviating is carried out by carrying out electricity irritation to driver acupuncture point when driver fatigue, the method has certain feasibility, but need, on driver's health, electric stimulation electrode is installed, make troubles to driver's operation, limit its range of application.The patent No. is the Chinese patent of CN 1424206A, disclose Soundwave releasing driving fatigue device, driver's auditory nerve maincenter is stimulated to alleviate driving fatigue by sending warning sound wave, the method has certain effect to either shallow driving fatigue, but for degree of depth driving fatigue DeGrain, cure the symptoms, not the disease, and without monitoring driving fatigue device.The patent No. is the Chinese patent of CN 104436407A, disclose a kind of infrasonic wave fatigue alleviating method and device, act on brain-induced people by infrasonic wave and enter sleep state fast with fatigue alleviating, the method can fundamentally fatigue alleviating, but cannot be applied to just at the human pilot of steering vehicle.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, provide a kind of and fundamentally fast, effectively can alleviate driving fatigue, the full-automatic infrasonic wave based on eegαwave alleviation driving fatigue method and device.
The present invention is achieved in the following ways:
Infrasonic wave based on eegαwave alleviates a driving fatigue method, it is characterized in that: gather driver's EEG signals under peace and quiet, eyes-open state, extract driver's eegαwave and preserve the data source as infrasonic wave signal; Infrasonic wave signal based on eegαwave signal is input to speaker system and then acts on driver head, to alleviate driver fatigue.
Above-mentioned a kind of infrasonic wave based on eegαwave alleviates the device of driving fatigue method, it is characterized in that: be made up of controller, power amplifier, speaker system, hydraulic system, fatigue monitoring device five part; Controller receives the driver fatigue early warning signal the output of hydraulic control system works and infrasonic wave signal that fatigue monitoring device imports into, power amplifier amplifies infrasonic wave signal and the signal after power amplification is input to speaker system, HYDRAULIC CONTROL SYSTEM speaker system position, fatigue monitoring device detects driver fatigue state and by working time of the feedback signal control loudspeaker system that is input to controller.Speaker system is made up of annular speaker array, chassis, annular speaker array to be arranged on chassis and inwardly and chassis axle centrage to have angle θ, angle theta be 15 °-165 ° adjustable, acoustic energy is focused on an A by self-focusing character by annular speaker array, adjusts angle theta by speaker system and driver head distance h.
This infrasonic wave alleviates driving fatigue method fundamentally can alleviate driving fatigue method fast, effectively.When the brain wave of people is in α ripple, the Consciousness of people, physical relaxation, in this state, human body energy expends minimum, and the energy that relative brain obtains is higher, and running will be quicker, smooth and easy, sharp.The data source of infrasonic wave signal comes from driver's eegαwave signal, utilizes " rhythm synchronization " character of brain brain wave to make tired driver quickly recover to the good mental status; And, due to different driver, eegαwave is different in the same state, makes the infrasonic wave effect based on eegαwave have very strong individual difference, generally better to the effect of driver own, and poor to other people effect, do not worry that infrasonic wave has influence on other people.This infrasonic wave alleviates the device of driving fatigue method can full-automatic operation, can combine, use simple, reliable and stable, be applicable to various types of motor vehicles with audio system in car.
