Problems solved by technology
[0003] Most of the existing airspace conflict judgment technologies are implemented based on the underlying API provided by the GIS engine. The types and graphic styles of various airspaces are varied, which is not conducive to the interaction between systems. At the same time, the inconsistency of airspace types leads to an increase in the calculation of airspace conflict judgments. , the performance is still good for small-scale airspace conflict detection, but for large-scale airspace conflict detection, the performance will decrease due to complex calculations

The invention provides a method and a system for detecting spatial conflict. The method comprises the following steps: receiving spatial information transmitted from outside; acquiring spatial information stored locally; decomposing the obtained external spatial information and the local spatial information into a combination of basic spatial areas, wherein the basic spatial areas include but arenot limited to cylindrical spatial areas, elliptical-cylindrical spatial areas, polygonal spatial areas and line segments; mapping the spatial information decomposed into the spatial areas and normalizing to an xy plane of unified coordinates as well as the z axis of a unified coordinate system; and selecting specification graphics of two spatial areas for comparison, and judging whether conflictexists or not through overlapping of the graphics, wherein the specification graphics of the two spatial areas are standardized graphics of the same type or standardized graphics of different types. Compared with the prior art, the method has the advantages that the spatial types and graphic styles used by users are unified, and a fast parallel spatial conflict detection method is used on the basis of a unified spatial interface, thereby improving the performance and success rate of large-scale spatial conflict judgment.
Description
technical field [0001] The invention relates to an airspace conflict detection method and system, and relates to the field of air traffic control. Background technique [0002] With the development of my country's national economy and the advancement of science and technology, general aviation and unmanned aerial vehicles are rapidly entering people's field of vision as emerging economic growth points. The result of future development will be that the types and numbers of aerial vehicles will continue to increase. The demands and conflicts of flying will also continue to increase. Therefore, under the premise of ensuring the safety of flight activities, reasonable planning of airspace, detection of conflicts in the use of airspace, meeting the needs of various airspace users, and improving the efficiency of airspace use will promote the further development of civil aviation, general aviation and UAV industries. [0003] Most of the existing airspace conflict judgment technol...
