摘　　要：针对目前机场跑道临时关闭助航设施的欠缺以及相关标准不统一,导致难以向飞行员在恶劣目视条件下和安全距离内提供醒目、有效的跑道关闭信息,给机场安全运行造成隐患等问题,提出建立基于人眼视觉特性的机场跑道临时关闭警示灯光模型,并采用逐点法对警示灯灯具光强进行了设计与分析,最后对警示灯进行警示这一过程进行了仿真。仿真结果表明,在2km处飞行员可分辨出警示灯X形,使飞行员能够清晰、准确、快速地辨别出跑道关闭,对飞行员起到了警示作用,为警示灯的研制提供了理论依据。Due to lack of navigation facilities of current airport runway closure and relevant standards disunified, it is difficult to pilots in harsh visual conditions and safe distance to provide eye-catching and effective runway closed information, which causes hidden dangers to airport safe operation. Aiming at this problem, this paper establishes a temporary airport runway shutdown warning light model based on human visual characteristics, designs and analyzes light intensity of warning light lamp by point by point method. Then warning process is simulated. Simulation results show that X-shaped warning light can be recognized at 2 km, and runway closed information can be distinguished by pilots clearly, accurately and rapidly. This plays a warning role for pilot and also provides theory basis for development of warning light.
