摘要
研究飞机着陆近地告警系统,为了研究近地告警系统中近地告警曲线阈值的计算方法,保证飞机安全性,提出了近地告警系统,同时对飞机的飞行运动模型和二维地形模型进行了深入的研究并进行仿真计算,提出了一种新的近地告警曲线计算方法,即实验统计法,并以近地告警系统对过大地形接近率报警为例,利用实验统计法进行了报警曲线的计算和拟合。将实验得到的报警曲线和标准的报警曲线进行比较,可以看出实验所得到的报警曲线与标准报警曲线十分吻合,进一步验证了方法的可行性和正确性,可为系统提供一种准确、简单的告警曲线阈值研究方法。
In order to calculate the alarm thresholds for Ground Proximity Warning System（GPWS）,this paper proposes a new method-experimental statistic method.The method is based on the analysis of the aircraft moving model and terrain model.To evaluate the proposed method,the mode 2 of GPWS is used as the test-bed.The experimental results show that the alarm thresholds calculated with the proposed method match those provided by standard GPWS very well,which proves the feasibility and accuracy of the proposed method.From the experimental results,this paper draws the conclusion that the experimental statistic method is an accurate and simple method.
