航路交叉点动态保护区的算法研究

繁忙的航路网产生大量的航路交叉点,不仅加重了空中交通管制员的工作负荷,也大大增加了冲突碰撞的可能性。为了减小交叉点处的碰撞风险,建立了交叉点保护区与飞行速度及航线角度的动态函数关系。首先,基于速度的正态分布概率理论,在给定安全目标等级条件下,求解相应的保护区大小;同时,对两机侧向间隔进行动态研究,求出保证两机距离达到最小安全间隔时的保护区大小,双重考虑取较大保护区范围。最后仿真验证了其可行性,算法可求出满意实时间隔,并保证航路安全。

Algorithm Research on dynamic protection aera of route intersection

The busy route network produces a lot of intersections, which not only aggravate the work load of ATC, but increases the probability of collision. To decrease the collision risk, this article builds the function relation between intersection reserve and airspeed and airline angle. Firstly , the article based on normal distribution probability theory of the speed, and find out the size of corresponding reserve area when given the certain security level. Then, it researches on dynamic lateral space of two airplanes and find out another reserve area. The final size is the larger one of them. At last, the simulation results verified the feasibility of this algorithm, it can calculate a satisfied real time interval and ensure the route security.
