摘要
在空中交通管制系统的研究中,关于飞行空中有效防止飞行器之间和地面障碍物间的碰撞问题,为解决飞行器在运动环境下短期冲突检测,提出设计了虚拟飞行器的短期冲突检测仿真系统,实现系统的结构和系统建模等过程。系统仿真了飞行器的飞行、起降和滑行等运动,对设计的卡尔曼滤波的分层检测算法进行了验证,实现了飞行器的短期冲突检测。仿真结果表明,算法对飞行器的状态进行了可靠的预测和判断,对飞行器的短期冲突检测实施了有效的预警,为空中交通通畅提供了保证。
To solve aircrafts＇ short-term collision detection in the motion,based on the application of air traffic control system,this paper used the virtual reality technology to design an aircrafts＇ short-term collision detection simulative system and introduced the process of forming and establishing the model of this system.This system simulated aircrafts＇ flight,rising and fall,sliding and so on,and validated the layered detective algorithm based on the design of kalman filtering,and actualized the aircrafts＇ short-term collision detection.The result of simulating indicates that this algorithm predicts and judges the condition of aircrafts reliably and makes the efficient warning about the aircrafts＇ short-term collision detection,and especially reduces the control personnel of workload.
