为了掌握高原公路海拔对驾驶员生理特性的影响规律,利用生物反馈系统对急进高原公路的驾驶员进行实地行车试验。通过定量分析,建立了驾驶员各项生理指标与试验路段海拔之间的关系模型。结果表明;高原公路行车驾驶员的各项生理指标都随海拔上升而表现出不同程度的变化;驾驶员心率增长率、LF/HF、LF以及脑电波“频段功率值与高原公路海拔成正相关,而表面肌电IEMG、血容振幅、HF指标与高原公路海拔表现出负相关性;其中,驾驶员心率增长率、LF/HF及脑电波”频段功率值三项指标与高原公路海拔的相关性较强,可以作为相关研究的备用指标。
In order to grasp the influence law of altitude on the physiological characteristics of drivers on the plateau, a biofeedback system was used to test the driving test of the driver on the steep plateau. Through the quantitative analysis, the model of the relationship between each physiological index and the elevation of the test section was established. The results showed that all physiological indicators of drivers on high altitude road showed different degrees of change with the altitude rising. The driver heart rate growth rate, LF / HF, LF and brainwave frequency were positively correlated with altitude , While the surface electromyography IEMG, hemorrhage amplitude, HF index and altitude of the plateau showed negative correlation; Among them, the driver heart rate growth rate, LF / HF and brain wave "frequency band power three indicators and the plateau highway elevation Relevant strong, can be used as a backup indicator of the relevant research.
