摘要:

针对当前均匀分布的仪表着陆系统(instrument landing system, ILS)信号无法反映出真实安全性变化的问题, 提出了基于高斯量化的ILS安全性信号设计方法。首先, 基于运行安全性确定安全范围并在此基础上进行逆向设计, 对飞行安全性进行高斯量化。然后, 从提高飞行员情景意识出发, 提出在安全范围内的不同偏移角度下, 仪表刻度变化率与安全性变化率保持一致的安全性信号设计方法。最后, 构建了飞行员认知模型, 在民机最后进近场景中, 对不同初始偏航角度进行了仿真实验。仿真实验结果表明, 所提方法提升了民机进近着陆阶段的安全性。

Abstract:

Aiming at the problem that the current uniformly distributed instrument landing system (ILS) signals cannot reflect the real safety changes, a Gaussian quantization based ILS safety signal design method is proposed. Firstly, based on operational safety, the safety range is determined and reverse design is carried out to perform Gaussian quantization on flight safety. Then, starting from improving the situational awareness of pilots, a safety signal design method is proposed to maintain consistency between the instrument scale change rate and the safety change rate at different offset angles within the safe range. Finally, a pilot cognitive model is constructed, and simulation experiments are conducted on different initial angle offsets in the final approach and landing scenario of civil aircraft. Simulation experiment results show that the proposed method improves the safety of the approach and landing phase of civil aircraft.

Key words: quantification of dynamic safety, reverse design, situational awareness, signal design of instrument landing system (ILS)
