空管系统中侵入区域告警及预警检测算法研究

Research on Algorithm of Invasion Area Warning and Predict Warning in Air Traffic Control System

在统一地心坐标系下,结合球面方位投影变换及逆变换,定义了目标坐标系以及在目标坐标系下的顶点象限标号和边标号,提出了特殊边标号处理算法及侵入区域的告警检测算法.根据飞行器的速度矢量,对飞行器是否有侵入区域的趋势进行了预警检测.经验证,此算法能准确地对飞行器侵入区域进行预警、告警.

Under the unified coordinate system of the earth's core, sphere azimuthal projection varied and inverse transformation are described. Methods of dot quadrant tab and border tab based on object coordinate system are introduced. Algorithms of special border tab and area invasion warning examination are discussed. According to the aircraft's velocity, the trend whether the aircraft will invade these areas is examined. Through proving, the algorithmcanreport an emergency and ask for help or increased vigilance to the aircraft accuratelywhen the aircraft invades the area.
