摘要
为提高机场场面的运行效率和安全水平,对机场场面展开飞行区安全预警研究.将航空器所处的空间转化为位姿空间,利用Minkowski和的方法构造位姿空间障碍,再结合人工势场法计算典型冲突场景下的风险值,并根据轨迹预测结果和风险阈值建立飞行区冲突预警模型.通过仿真案例分析,得出3种冲突类型在基本行驶模型和基于构型空间的冲突模型下进入潜在冲突区的时间和最晚解脱时间.结果得到:相向冲突前者进入潜在冲突区的时间为1.82 s,后者为2.12 s;前者最晚解脱时间为4.67 s,后者为4.89 s.跟随冲突前者进入潜在冲突区的时间为1.44 s,后者为1.56 s;前者最晚解脱时间为2.86 s,后者为3.01 s.交叉冲突前者进入潜在冲突区的时间为3.57 s,后者为3.80 s;前者最晚解脱时间为5.10 s,后者为5.33 s.结果表明:基于构型空间的冲突风险度量模型能够更精确地判断进入冲突区的时间.
Abstract
To improve the operational efficiency and safety level of airport operations,a study on flight area safety warning on airport surfaces is being conducted.The spatial location of aircraft is transformed into a pose space,obstacles in the pose space are constructed using the Minkowski method,and risk values in typical conflict scenarios are calculated using an artificial potential field method.A flight area conflict warning model is then established based on trajectory pre-diction results and risk thresholds.Through simulation case analysis,the time of entry into the potential conflict zone and the latest escape time for three conflict types are obtained under the basic driving model and conflict model based on con-figuration space.The results show that in head-on conflicts,the time of entry into the potential conflict zone is 1.82 s for the former and 2.12 s for the latter,with the latest escape time being 4.67 s for the former and 4.89 s for the latter.In o-vertaking conflicts,the time of entry into the potential conflict zone is 1.44 s for the former and 1.56 s for the latter,with the latest escape time being 2.86 s for the former and 3.01 s for the latter.In crossing conflicts,the time of entry into the potential conflict zone is 3.57 s for the former and 3.80 s for the latter,with the latest escape time being 5.10 s for the former and 5.33 s for the latter.The results indicate that the conflict risk measurement model based on configuration space can more accurately determine the time of entry into the conflict zone.
