【摘要】 助航灯光系统为夜间或能见度较低环境下飞机的安全起降提供安全保障。快速准确地测量和判断其光强等级、光照射角等是否符合国际民用航空组织(ICAO)的标准,是保障机场安全运行的重要工作。本文设计了基于硅光电池的照度探测器,通过余弦校正器和不同滤光片的组合完成视见函数校正和照度探测的精度标定,实现了灯光的高速动态检测;完成了光照度探测器的线性标定和动态精度测量实验,照度测量误差率和动态测量误差均满足ICAO规定的要求;实现了助航灯光平行截面内光强的高速动态检测。更多还原

【Abstract】 The airfield lighting system provides safety for the take-off/landing safe of aircraft at night or in low visibility environments. It is an important task to measure and judge quickly and accurately whether the light intensity level, light illumination angle, etc. meet the standards of the International Civil Aviation Organization(ICAO) to ensure the safe operation of the airport. In this paper, the illuminance detector based on the silicon photocell is designed. The visibility curve V(λ) is completed by the combination of cosine corrector and different filters, realizing the high-speed dynamic detection technology accurately. The linear calibration and dynamic accuracy measurement of the illuminance detection is completed by experiments. The illuminance measurement error rate and the dynamic measurement error meet the requirements of ICAO regulations. The high-speed dynamic detection of light intensity in parallel sections of navigation aids is realized.更多还原
