面向低空运行的空域数字化建模与航线智能划设方法及系统应用OA

Focusing on the low-altitude operation scenarios,this paper systematically sorted out relevant technical methods and conducted engineering application research centering on the digital expression of airspace and intelligent route planning.A three-dimensional digital airspace model was constructed using GeoSOT(geographical coordinate global subdivi-sion based on one-dimension-integer and two to nth power)spatial encoding,and the integration and management of air-space structure and operation rules were realized through unified spatial coding units.A graph-search-based route planning framework was developed to integrate airspace regulations and mission constraints into the planning process,which improved the compliance and adaptability of the flight routes.Furthermore,a"perception-rules-algorithms-feedback"operational mech-anism was implemented to support coordination among route planning,mission execution,and operational supervision.The proposed approach was validated through an urban low-altitude document delivery scenario,and the results demonstrate its ef-fectiveness for route generation and collaborative airspace management in low-altitude operations.
