Airport snow pavement condition evaluation method and device
The invention discloses an airport snowy pavement condition evaluation method. The method comprises the following steps: 1) acquiring a scattering image of a snowy runway; 2) estimating the thickness and the liquid water content of the accumulated snow according to the scattering area and the scattering intensity of the obtained image; 3) based on the aircraft tire three-dimensional model and the corrected Delk-Prasugrel cap accumulated snow model, performing numerical simulation on an accumulated snow runway to obtain friction coefficients of accumulated snow with different thicknesses and liquid water contents, and establishing a database; 4, the database is called, and the accumulated snow pavement friction coefficient under the corresponding thickness and liquid water content is obtained.The laser emitting device and the light scattering sensor can remotely detect accumulated snow in real time, and normal taking-off and landing of an airplane are not affected.
本发明公开了一种机场积雪道面状况评估方法，包括如下步骤：1）获取积雪跑道的散射图像；2）根据获取图像的散射面积和散射强度预估积雪的厚度和液态含水量；3）基于飞机轮胎三维模型和修正的德鲁克－普拉格盖帽积雪模型，对积雪跑道进行数值模拟，得到不同厚度和液态含水量下积雪的摩擦系数，并建立数据库；4）调用数据库，获得相应厚度和液态含水量下的积雪道面摩擦系数。本发明的激光发射装置及光散射传感器可实时和远程地对积雪进行检测，且不影响飞机的正常起降。
