The device mainly includes the following parts: an EEG acquisition circuit; the EEG acquisition circuit includes an EEG acquisition electrode, an EEG module; a single-chip computer is provided with calculation software of EEG bi-spectral index; the output end will display the control signals of the stimulation of electrical pulses, after the human spirit reaches to a certain extent; the output end is connected with the electrical stimulator; the electrical stimulator is a structure with an elastic and belt-shaped head ring; the electrical stimulator is provided with an EEG acquisition electrode chip and a stimulating electrode. The utility model has the function of directly measure the brain function; the device can remind on time the drivers falling into sleep (or a little sleepy) of the current dangerous conditions; the use of electrical stimulation better intensified the reminding results.
Description
Technical field
This utility model relates to a kind of device that the people is carried out safety monitoring and the excited stimulation of enforcement under fatigue state.
Background technology
The reason that causes fatigue driving is that the economic dispatch factor causes, and shows the driving of interests, and the tired consequence that causes is the reduction of driver's brain excitement degree, and reaction is slowed down, so that enters sleep.At present, the Monitoring and Controlling technology that tired driver is driven has multiple, as: the motion of tracking driver eyeball, eyelid are blinked to wait and are measured tired method indirectly.Measure owing to belong to indirectly, therefore exist not science of the tired objective indicator of monitoring, cause measurement effect undesirable, sensitivity is also relatively poor.If the brain function state to the driver is monitored in real time, the particularly appearance of brain electricity bispectrum index technology just can be monitored driver's fatigue driving state the most direct, accurately, delicately in real time, promptly its brain function excitement levels is monitored.The brain function Condition Monitoring Technology has begun to be applied to the patient when hospital surgical is anaesthetized, topmost monitoring index is exactly a brain electricity bispectrum index, it have linearity, in real time, advantages such as high anti-jamming capacity and sensitivity.For these reasons, the brain function monitoring technology is used for tired driver degree Monitoring and Controlling and has possessed the most direct technical foundation.
Summary of the invention
The purpose of this utility model provides a kind of tired driver and drives monitoring and feedback stimulation instrument, monitors driver's fatigue driving state the most directly, accurately, delicately in real time with solution, and in time implements the technical problem of excited stimulation.
Tired driver described in the utility model drives monitoring and feedback stimulates instrument mainly to comprise as the lower part:
The brain wave acquisition circuit, this circuit comprises: brain wave acquisition electrode, the brain electricity module that is connected with the brain wave acquisition electrode; Brain electricity module comprise the big circuit of brain tele-release and A the D change-over circuit;
One-chip computer, this one-chip computer input is connected with brain electricity module outfan, and the software that EEG signals is carried out brain electricity bispectrum Index for Calculation is housed, its outfan is after human body mental excitation state acquires a certain degree, output control electric pulse stimulation signal, this outfan is connected with electrostimulator;
Electrostimulator, this electrostimulator are the structure of elastic banded head circle, and on electrostimulator, the corresponding EEG signals place of picking up is provided with the brain wave acquisition electrode slice, and place, corresponding brain mental excitation acupuncture point is provided with stimulating electrode; Described stimulating electrode is connected with the control electric pulse stimulation signal output part of one-chip computer by constant-current circuit, power amplification circuit and buffer circuit successively.
Aforesaid tired driver drives monitoring and feedback stimulates instrument, between brain electricity piece and one-chip computer, is connected with an anti-jamming circuit.
Aforesaid tired driver drives monitoring and feedback stimulates instrument, and an output control terminal of one-chip computer is connected with an acoustical generator.
The utlity model has the function of direct measurement brain function state, it can real-time reminding enters the present unsafe condition of driver of sleep (or early stage) state, adopts the mode of electricity irritation to strengthen the effect of prompting more.The accuracy of this instrument, sensitivity, real-time and anti-interference ability are higher, can reduce greatly by tired driver and drive the accident rate that causes.
Description of drawings
Fig. 1 is a schematic block circuit diagram of the present utility model.
The specific embodiment
Main circuit of the present utility model is formed referring to Fig. 1.Comprise brain wave acquisition, one-chip computer, electrostimulator and sound send device.Brain wave acquisition is made up of five metal electrodes, the brain electrolemma piece that are installed in the electrostimulator.Its midbrain electricity module comprises amplifying circuit, A/D change-over circuit, and EEG signals is fed in the one-chip computer.Above-mentioned eeg signal acquisition electrode is distributed in place, human body electroencephalogram's signal acupuncture point by gathering requirement.
One-chip computer utilizes discrete digital signal processing algorithm extract real-time and people's the relevant characteristic index of the mental status (function of nervous system) to gathering EEG signals, and as feedback signal, electricity irritation and audible alarm are exported in control.
Electrostimulator is a banded coil structures, and the corresponding acupuncture point of human brain that has two electrode slices as stimulating electrode to be located on the electrostimulator is located.Noinvasive Constant Electric Current stimulus signal sends impulse wave by single-chip microcomputer, through circuit such as isolation, power amplification, constant currents, puts on the some positions of human body by surface electrode, and Current Control is in 40 milliamperes of scopes, and size and frequency change controlled according to EEG signals.Electrostimulator can also comprise a simple acoustical generator, and this simple acoustical generator is connected with one-chip computer, plays the aid prompting effect.
Described EEG signals is to obtain the human biological signal by sticking in the surface electrical pole piece of brain, amplifies through amplifying circuit, becomes digital quantity after the A/D conversion, is read by the monolithic computer, obtains corresponding brain wave.
It can be widely used in drives and key post adds that safety monitoring is carried out in the sleepy sleep of personnel on duty and implement excited the stimulation under fatigue state tired driver.
