基于低空风险有向网络推演的飞行安全控制方法及系统
By constructing a low-altitude risk directed network, calculating navigation and flight errors, and extrapolating expected safety levels, the problem of insufficient safety in low-altitude operations in existing technologies is solved. This enables a systematic characterization and control of low-altitude operation risks, thereby improving the safety level.

AI Technical Summary
Existing technologies cannot systematically characterize the complex risk relationships of low-altitude operations, lack the ability to construct a hierarchical and networked risk evolution system, lack precision in setting safety intervals, fail to effectively integrate navigation performance errors and flight technology errors, cannot achieve advance prediction and dynamic adjustment, and have limited safety control methods, making it difficult to improve the safety level of low-altitude operations.
A low-altitude risk directed network is constructed. By calculating navigation performance error and flight technology error, avoidance interval and safety interval are determined. Combined with the time delay transmission and accumulation process, the expected safety level is deduced, and a control scheme is output to achieve the target safety level.
It enables a systematic characterization and control of the risk evolution process of low-altitude operation, quantifies the expected safety level, improves the safety and control efficiency of low-altitude operation, and meets the safety requirements of different collision scenarios.
