【摘要】：为了揭示驾驶员在高原公路行车时的心率变异性的变化情况,寻求提高行车安全性的途径,利用生物反馈仪在高原公路上进行了实地行车测试。以频域指标LF/HF作为高原公路驾驶员心率变异性指标,在分析驾驶时间、海拔高度与驾驶员心率变异性指标之间关系的基础上,建立了相关模型。分析结果表明:驾驶员在高原公路行车时,心率变异性受到高原低氧环境和驾驶时间的双重影响;海拔越高,驾驶时间越长,驾驶员交感神经张力越大,使驾驶员疲劳程度增大,安全隐患增大。
[Abstract]:In order to reveal the variation of heart rate variability of drivers on highland highway and to find a way to improve the safety of driving, the field driving test was carried out on plateau highway with biofeedback instrument. Based on the analysis of the relationship between driving time, altitude and drivers' heart rate variability (HRV), a correlation model was established based on the frequency-domain index (LF/HF) as an indicator of heart rate variability (HRV) of highway drivers at high altitude. The results show that the heart rate variability is affected by the altitude hypoxia environment and driving time, the higher the altitude, the longer the driving time, the greater the tension of sympathetic nerve. The driver fatigue degree increases, the safety hidden danger increases.
