[0025] Example

[0026] Such as figure 1 As shown, the present invention designs a wearable fatigue driving monitoring system based on forehead EEG signals, which includes a forehead EEG signal acquisition module, a fatigue state recognition module, a result feedback and intervention module, and a device power supply module. The forehead EEG signal acquisition module, the fatigue state recognition module, the result feedback and intervention module are connected through the Bluetooth transmission module, and the device power supply module provides power to them.

[0027] The forehead EEG signal acquisition module includes acquisition electrodes, preprocessing circuits, amplification circuits, and A / D conversion circuits connected in sequence. The pre-processing circuit includes a second-order passive low-pass filter circuit and a limiter circuit to eliminate high-frequency interference and overvoltage protection; among them, the low-frequency cut-off frequency is 40kHz, and the pas...

Abstract

The invention belongs to safe driving detection technology, and relates to wearable fatigue driving monitoring system and method based on forehead electroencephalogram signals. The system is capable of monitoring fatigue state of a driver in real time, high in judgment accuracy, timely in early warning and intervention, comfortable to wear and convenient to carry. The system comprises a forehead electroencephalogram signal acquisition module, a fatigue state identification module and a result feedback and intervention module which are sequentially connected and all arranged on a wearable headband, wherein the forehead electroencephalogram signal acquisition module is used to acquire the forehead electroencephalogram signals of the driver and transmit the acquired electroencephalogram signals to the fatigue state identification module in real time; the fatigue state recognition module is used to analyze the received electroencephalogram signals, carry out data preprocessing and featureextraction, perform fatigue state recognition by adopting an algorithm model obtained by off-line training and send recognition results to the result feedback and intervention module; and the result feedback and intervention module is used to remind and intervene the driver when receiving the fatigue state transmitted by the identification module.

Description

technical field [0001] The invention belongs to safe driving detection technology, in particular to a wearable fatigue driving monitoring system and method based on forehead electroencephalogram signals. Background technique [0002] Globally, fatigue driving has become one of the important causes of traffic safety accidents. Fatigue driving will lead to the driver's inability to concentrate, decrease in reaction speed, and decrease in control of the vehicle, which will seriously increase the probability of traffic accidents. Therefore, it is of great significance to study the detection of fatigue driving for accident prevention and improvement of traffic safety. If the wearable device can detect the fatigue response in the early stage of the driver's fatigue, and issue an alarm to attract the driver's attention, it can effectively protect the driver's life and property safety. [0003] The main existing fatigue driving monitoring technologies are mainly motion capture met...
