Description

Risk assessment system and method for low-altitude flight based on risk assessment model Technical Field The application relates to the technical field of traffic management, in particular to a risk assessment system and a risk assessment method for low-altitude flight based on a risk assessment model. Background At present, with the rapid development of the unmanned aerial vehicle industry, the flying activities of unmanned aerial vehicles are increasingly frequent, and effective supervision on the operation safety of unmanned aerial vehicles becomes an urgent need. Today, risk assessment for unmanned aerial vehicle flight is mostly dependent on international methods such as relevant regulatory frameworks and SORA. However, conventional risk assessment models are typically static, with fixed weights and parameters. On the basis, the approver can only evaluate according to the risk evaluation standard of the existing model, and the evaluation process depends on personal experience of the panelist to a great extent, so that the evaluation result can be disjointed from the actual risk condition, or potential safety hazards are brought too loose, or the industrial development is restricted too strictly. Disclosure of Invention Based on the risk assessment system and method for low-altitude flight based on the risk assessment model, the low-altitude flight risk assessment system and method are good in adaptability and flexibility.
