【摘要】：本论文主要对驾驶人员视觉疲劳影响程度问题进行光度学的研究。从驾驶人员视觉疲劳的成因入手,通过人机工程学理论分析视觉疲劳因子对驾驶员的影响机制,从动态视觉特性、中间视觉理论、周边视场视觉特点以及非视觉生物效应等方面对高速公路低灯位照明灯具光色对驾驶人员视觉疲劳的影响进行理论研究,并进行实验研究、比对与分析,利用得出的结果对灯具设计的优化提出指导意见。论文总体分为六个部分展开:第一部分论述研究背景和意义,引出道路照明这一因素对驾驶人员视觉疲劳影响的现状研究。第二部分基于人机工程学理论探讨视觉疲劳因子对驾驶人员的影响机制,提出对视觉疲劳抑制的前提因素。第三部分论述静止状态下的光色对驾驶人员视觉疲劳研究存在的问题,并通过研究动态状况下的视觉特性,分析驾驶人员的在高速状态下的光色以及光色的周期变化频率等因素对其视觉的影响。第四部分结合道路照明环境,研究在中间视觉下周边视场的视觉特性,提出综合分析中间视觉、周边视场特性以及非视觉生物效应对驾驶人员的视觉影响,基于此研究在夜间高速行驶状态下周边视场内的光色变化对视觉特性的影响。第五部分基于闪光频率融合的视觉疲劳程度测试方法,通过模拟夜间高速驾驶环境,研究三种光源光谱对高速行进中的驾驶人员视觉疲劳的影响程度,并通过影响程度比对,分析得出蓝光光谱有利于延缓视觉疲劳。同时研究光色的不同周期变化对视觉疲劳的影响,通过五组不同变化周期的视觉疲劳对比实验,得出高速驾驶时,每2.25公里变化一次光色最有利于视觉疲劳的抑制。从而从光色和周期变化频率两个方面综合考虑低灯位道路照明灯具光色的设计。最后一部分是对论文的总结和展望,论文的研究由于实际条件的限制,相对比较粗略,希望后续研究者在光色光谱的选择以及周期频率的设置方面有更多的对比研究,进一步探索光色以及周期变化频率对视觉疲劳的影响,使道路照明灯具光色设计达到更好的抑制视觉疲劳的效果。
[Abstract]:In this paper, the influence of visual fatigue on drivers was studied by photometry. Starting with the causes of driver's visual fatigue, this paper analyzes the influence mechanism of visual fatigue factor on driver by ergonomics theory, from dynamic visual characteristics, intermediate visual theory, The visual characteristics of peripheral field of view and non-visual biological effects are studied theoretically, and the effects of light and color on the visual fatigue of drivers are studied, compared and analyzed. Using the results obtained to optimize the design of lamps and lanterns put forward guidance. The thesis is divided into six parts: the first part discusses the background and significance of the study, leading to the impact of road lighting on visual fatigue of drivers. In the second part, based on ergonomics theory, the influence mechanism of visual fatigue factors on drivers is discussed, and the premise factors of visual fatigue suppression are put forward. The third part discusses the problems existing in the study of the visual fatigue of drivers under the condition of light and color at rest, and through the study of the visual characteristics of the dynamic state, The influence of the driver's light color at high speed and the cycle frequency of the light color on the vision is analyzed. The fourth part combines the road lighting environment, studies the visual characteristics of the peripheral field of view under the intermediate vision, and proposes a comprehensive analysis of the visual effects of the intermediate vision, the peripheral field of view and the non-visual biological effects on the driver. Based on this study, the influence of light and color changes in the peripheral field of view at high speed at night on the visual characteristics is studied. The fifth part is based on the flash frequency fusion visual fatigue test method, by simulating the night high-speed driving environment, the influence of three light sources spectrum on the visual fatigue of the driver in high-speed travel is studied, and the influence degree ratio of the three kinds of light source spectrum on the visual fatigue of the driver is compared. The blue spectrum is helpful to delay visual fatigue. At the same time, the influence of different cycle changes of light color on visual fatigue is studied. Through five groups of comparative experiments of visual fatigue with different periods, it is concluded that the change of light color every 2.25 km at high speed driving is most beneficial to the suppression of visual fatigue. Therefore, the light color design of low level road lighting lamps is considered synthetically from two aspects of light color and periodic variation frequency. The last part is the summary and prospect of the thesis. Due to the limitations of the actual conditions, the research is relatively rough. I hope that the follow-up researchers will have more comparative research on the choice of light color spectrum and the setting of periodic frequency. Furthermore, the influence of light color and periodic frequency on visual fatigue is explored, so that the light color design of road lighting lamps can reduce visual fatigue better.
