The invention provides an assignment method based on airspace grids, and belongs to the field of air traffic management. The method specifically comprises the following steps: firstly, performing grid recursion division on a target airspace; for each aircraft in the target airspace at the moment t = ta, according to the real-time flight dynamics, meteorological information and flight plans, parameters are given to the position of each aircraft in each sub-grid, and a deterministic grid assignment matrix is formed; meanwhile, according to errors existing in the flight process of the aircrafts, a probability type grid assignment matrix is established, and the probability of the actual sub-grids where the aircrafts are located is assigned; and finally, respectively calculating the complexity of the target airspace, the flight flow in the grids and the collision probability by using the determined grid assignment matrix and the probabilistic grid assignment matrix of each aircraft, and providing reference data for air traffic control. According to the method, the airspace grid units are used as a basic underlying framework of spatial motion modeling, and visualization, quantification and precision of an airspace traffic management system are realized.

    本发明提供了一种基于空域网格的赋值方法,属于空中交通管理领域;具体为:首先,对目标空域进行网格递归划分;在t=ta时刻针对目标空域的各个航空器,根据实时的飞行动态、气象信息和飞行计划,对各航空器在每个子网格的位置分别赋予参数,构成确定型网格赋值矩阵;同时,根据各航空器在飞行过程中存在的误差,建立概率型网格赋值矩阵,并对各航空器所在的实际子网格的概率进行赋值;最后,利用各航空器的确定型网格赋值矩阵和概率型网格赋值矩阵分别计算目标空域的复杂度、网格内飞行流量和碰撞概率,为空管提供参考数据;本发明以空域网格单元作为空间运动建模的基础底层框架,实现空域交通管理系统可视化、定量化和精确化。
