摘要
当前民用飞机驾驶舱内导光板照明采用手动亮度调节方式,既增加驾驶员负担,又不易根据驾驶舱光环境精准控制导光板亮度,本文深入研究了导光板照明系统的自适应调光控制技术。通过驾驶舱三维建模及SPEOS光学仿真建立了光分布概况,确定了环境光照传感器的布局,并通过对驾驶舱光环境的人机工效试验及置信区间统计学分析,确立了亮度调光曲线模型。在此基础上,提出了导光板照明自适应调光控制理想模型,研究成果为飞机设计领域的应用提供了理论依据。
Considering that manual adjustment of the light guide plate illumination for civil aircraft cockpit not only increases the pilot＇s workload, but also has difficulties in precisely controlling the brightness of light guide plate according to cockpit light environment, we studied the self-adaptive dimming control technology for the lighting system of light guide plate. Ambient light distribution in different areas was established through cockpit 3D modeling and SPEOS optical simulation, the layout of ambient light sensors was determined, and the brightness dimming curve model was established through ergonomics test for cockpit light environment and statistical analysis of confidence interval. Based on which, an ideal model of self- adaptive dimming control for the light guide plate illumination was proposed, which provides a theoretical basis for application of the research result in the field of aircraft design.
