驾驶舱照明可用性综合评估方法及应用

Comprehensive Evaluation Method and Application ofCockpit Lighting Availability

驾驶舱复杂外部光环境易对飞行员造成视觉疲劳、行为、生理及情绪等不利影响。通过自动调光照明系统提高驾驶舒适性,保证飞行安全是提高驾驶舱人机工效水平的重要手段。本文提出一种典型外部光环境下驾驶舱照明系统的可用性综合评估方法。从有效性、效率、满意度三个维度对四种器件参数设置方案进行评估,采用层次分析法对显示器、指示灯、导光板、泛光灯四种自动调光器件重要性权重进行计算,得到驾驶舱可用性综合评分。本文提出的方法可以实现对驾驶舱自动调光照明系统的可用性定量评价,为飞机驾驶舱可用性系统优化设计提供依据。

The complex external light environment of the cockpit is prone to adverse effects on pilots,such as visual fatigue,altered behavior,physiological changes,and emotional responses.Improving driving comfort through an automatic dimming lighting system and ensuring flight safety is an important means to improve the ergonomic level of the cockpit.This article presents a comprehensive evaluation method for the usability of the cockpit lighting systems under typical external light environments.Four device parameter setting schemes are evaluated from the three dimensions of effectiveness,efficiency,and satisfaction.The analytic hierarchy process is used to calculate the importance weights of the four automatic dimming devices,namely displays,indicator lights,light guide plates,and floodlights,and the comprehensive usability score of the cockpit is obtained.The proposed method can realize the quantitative evaluation of the usability of the cockpit’s automatic dimming lighting system,providing a foundation for the optimal design of the aircraft cockpit usability system.
