基于生理信號的駕駛疲勞綜合評價指標(biāo)的試驗研究
[Abstract]:The booming automobile industry has brought comfort and speed to our life, but the negative effects caused by it are also obvious. The increase of road traffic accidents has brought great harm to people's lives. Among the many factors leading to road traffic accidents, fatigue driving is one of the main reasons. Fatigue driving directly leads to almost 20% of the total number of road traffic accidents. Therefore, it is of great significance for the prevention and control of traffic accidents to study driving fatigue and find ways to prevent and alleviate driving fatigue. The main work of this paper is as follows: (1) the influencing factors and formation mechanism of driving fatigue are discussed, and the research methods and present situation of driving fatigue based on physiological index testing are summarized in detail. According to the research indexes of driving fatigue physiological test at home and abroad, such as heart rate, blood pressure, respiration, body temperature, EEG, muscle resistance, gastrointestinal electricity, evoked potential, blood oxygen saturation, saliva and so on. Experimental maneuverability, ease of operation, experimental requirements and other factors, the final determination of ECG, EEG, respiratory frequency, body temperature, Five physiological signals of muscle resistance are used as the test indexes. (2) A driving simulation platform for driving fatigue physiological index testing is constructed. Design and build driving simulation platform to test physiological indexes in simulated driving. The system mainly includes CS310t-1 integrated simulation driving system to simulate the real driving environment. The MP150 multichannel physiological instrument imported by the United States, including an amplifier for amplifying physiological signals, sensors for sensing human bioelectrical signals and a self-contained computer software Acqknowledge. (3) for data analysis, has designed the test process for driving fatigue physiological indicators. And the implementation of the test operation. Twenty students were selected as the subjects. According to the experimental procedure, the electrocardiogram (ECG), electroencephalogram (EEG), respiratory frequency, body temperature and muscle resistance of the subjects during the driving task for 50 minutes were measured. The computer records and saves the experimental data. (4) signal processing is carried out by the physiological instrument software Acqknowledge, and then the experimental data are analyzed and discussed. Firstly, the mathematical models of general linear regression analysis and stepwise linear regression analysis are introduced, and the two regression methods are analyzed and compared by using R software. The results show that many variables are not significant in the comprehensive index equation of driving fatigue based on general linear regression analysis, but the comprehensive index equation of driving fatigue based on stepwise linear regression method avoids this shortcoming. Finally, regression verification and reliability verification are used to show that the driving fatigue comprehensive index can well reflect the driver's fatigue state. (5) the determination of driving fatigue comprehensive index based on principal component regression analysis. Firstly, the mathematical model of principal component regression analysis is introduced, and the comprehensive index equation of driving fatigue is obtained by means of principal component regression analysis. Regression verification and reliability verification of the obtained regression equation show that the obtained comprehensive index of driving fatigue can effectively reflect the driver's driving fatigue state.
