Driver brain wave collecting and analyzing system based on data fusion

Abstract

The invention discloses a driver brain wave collecting and analyzing system based on data fusion. The system comprises a head-mounted brain wave collecting device, an automobile movement information collecting device, a main controller and a PC upper computer, wherein the head-mounted brain wave collecting device comprises a brain wave collecting electrode module, a preprocessing module and a wireless communication module, and the brain wave collecting electrode module is connected with the preprocessing module and used for collecting brain wave signals and transmitting the brain wave signals to the preprocessing module; the preprocessing module is used for preprocessing the brain wave signals and is connected with the wireless communication module, the wireless communication module is in wireless connection with the PC upper computer, and the preprocessing module transmits the preprocessed brain wave signals to the PC upper computer on the basis of wireless communication. By means of the system, brain wave monitoring in a static environment can be achieved, driver brain waves and automobile movement information are synchronously monitored in the automobile running process, the real-time mental state of a driver is obtained through analysis and processing, and the system has a fatigue driving reminding function.

Description

technical field [0001] The invention relates to the technical field of fatigue analysis systems, in particular to a driver's brain wave acquisition and analysis system based on data fusion. Background technique [0002] Fatigue driving refers to the phenomenon that the driver's physiological and psychological functions are out of balance after driving continuously for a long time, so that the driving skills decline objectively. If you continue to drive a car after fatigue, you will feel drowsy, drowsy, weak in limbs, inattentive, poor in judgment, even in a trance or instant memory loss, delayed or premature action, operation pause or improper correction time and other unsafe factors. Highly prone to road traffic accidents. The brain wave is formed by the sum of the synchronous post-synaptic potentials of a large number of neurons when the brain is active. It records the electric wave changes during brain activity, which is the overall reflection of the electrophysiologica...

AI Technical Summary

Problems solved by technology

[0003] With the development of the times, brain wave monitoring devices are widely used in the monitoring of fatigue driving. The brain wave monitoring devices in the prior art generally only monitor and analyze the driver's brain waves. The interference caused by the monitoring of the electric wave signal, so the general EEG monitoring device can only monitor and display the EEG waveform in a static environment, and cannot be applied to the monitoring of the driver's EEG in the actual driving process.
