Embodiment

[0211] Taking graduate student Wang as an example, he wears the wristband terminal 1 and the head-mounted terminal 2 described in the present invention, and the driver’s road rage state recognition system based on the fusion of EEG and pulse information is connected with a buzzer as a road sensor. The anger alarm device was turned on, and the equipment switch was turned on. He drove a small car on Gongxue Road, Nanling Campus, Jilin University.

[0212] 1. Simulate the normal driving of the driver:

[0213] Wristband terminal 1 collects Wang's pulse information in real time and performs preprocessing, and head-mounted terminal 2 collects Wang's EEG signals in real time and performs preprocessing; in wristband terminal 1, the pulse information of 5 seconds is used each time Extract the pulse feature and transmit it to the head-mounted terminal 2 via Bluetooth. In the head-mounted terminal 2, each time the EEG signal is used for 5 seconds to extract the EEG feature; then, the he...

Abstract

The invention discloses a driver's road rage state recognition method based on EEG and pulse information. In order to overcome the problems of high power consumption and being easily affected by external conditions in the prior art, the steps of the recognition method are as follows: 1) collect the driver The pulse information and EEG signal of the driver are preprocessed: (1) the wristband terminal collects the pulse information of the driver and performs preprocessing; (2) the head-mounted terminal collects the driver’s EEG signal and performs preprocessing; 2) respectively Feature extraction of driver's pulse information and EEG signal: (1) feature extraction of driver's pulse information; (2) feature extraction of driver's EEG signal; 3) driver's EEG feature and pulse feature Fusion and dimensionality reduction; 4) Train the driver's road rage state discrimination classifier; 5) Real-time judgment on the driver's road rage state: the trained road rage state discrimination classifier is used to judge the driver's road rage state in real time. When the result is "yes", the driver is prompted.

Description

technical field [0001] The invention relates to a method belonging to the technical field of traffic safety driving and intelligence, more precisely, the invention relates to a driver's road rage recognition method based on the fusion of EEG signal processing and pulse information processing. Background technique [0002] "Road rage" is a kind of driving anger caused by frustration and pressure. It belongs to paroxysmal rage disorder. The driver will actively obstruct, provoke and other excessive behaviors, endangering the safety of others and himself. According to statistics, the proportion of traffic accidents caused by violent driving behavior is becoming more and more serious. Studies have shown that quite a few drivers have these symptoms, but not everyone can have a clear understanding of their emotions during the onset of symptoms. If driving emotions cannot be detected and eliminated in time, it will deteriorate into traffic accidents. Therefore, it is the key to pr...
