The purpose of this utility model is achieved through the following technical solutions: a kind of wearable driver's eeg signal acquisition headband, comprise headband and power supply, headband is hollow structure in the form of a ring, the dry electrode of eeg signal acquisition be arranged at inside headband is connected by cable with the eeg signal acquisition device chip that headband inside is arranged, two pieces of eeg signal acquisition chips in parallel are connected with wireless data transmission chip respectively by cable, the battery capacity indication lamp of the front outer setting of headband is connected with wireless data transmission chip, power series on and off switch is connected with eeg signal acquisition device chip.
The loop that the dry electrode of described eeg signal acquisition and eeg signal acquisition device chip and wireless data transmission chip are formed is two groups, is symmetrical arranged.
Described eeg signal acquisition chip is TGAM integration module, and sample frequency is 512Hz; Wireless data transmission chip is FBT06 bluetooth module, and the baud rate of transmission is 57600B, connects between involved components and parts respectively by cable.Described headband is the woven materials of partial-band degree of tightness.
Work process of the present utility model and principle are:
This utility model is to detect the driving condition of driver in driving procedure and custom-designed headband, needs the eeg data collected by dry for eeg signal acquisition electrode by wireless data transmission chip by the vehicle-mounted monitoring system of the Signal transmissions after process to automobile during use.By vehicle-mounted monitoring system, real time record, analyzing and processing are carried out to the signal received, differentiate the driving condition of driver.This headband is worn over head by driver, is arranged at the dry electrode of brain wave acquisition inside headband zone position after the left temporo back zone of corresponding human brain and right temporo respectively; After power supply opening, two dry electrodes of eeg signal acquisition are started working, the EEG signals of Real-time Collection driver; The EEG signals collected is after the pretreatment such as denoising, and the algorithm re-using Its Sparse Decomposition and compressed sensing carries out the Alertness detection of driver, obtains the Alertness information of driver; The deceleration device of driver's Alertness information control automotive interior exported and the work of the hazard warning lamp of automobile; If driver is in fatigue state, wherein automobile will slowly slow down; And the driver of automobile in continuing to travel towards periphery is sent warning, with the generation avoided traffic accident by the hydropac flash lamp of automobile.
Compared with prior art, the beneficial effects of the utility model are:
This utility model is head-type, and volume is little, light, can wear common headband and directly wears on driver's head by picture, wear convenience; Can not cause discomfort to the head of driver simultaneously, thus can not affect the normal driving operations of driver, driver is easy to accept.
