基于灰色模糊理论的航测无人机飞行安全风险评价

Research on Risk Evaluation of UAV Flight Safety Based on Gray Fuzzy Theory

无人机飞行安全评价是无人机飞行管理中的一个重要环节。本文以Trimble UX5航测无人机为例,在阐述无人机飞行特点的基础上,运用Delphi法及文献收集法识别风险因素,优选确定了无人机飞行安全风险指标体系;利用序关系分析法确定了无人机飞行安全风险因素权重,结合灰色模糊理论构造了无人机飞行安全灰色模糊评价模型,将灰色和模糊的不确定内容转化为可以准确衡量的数值,为决策者决定飞行计划提供依据。最后将评价模型应用于平舆县水生态文明城市规划飞行安全管理中,证明了模型的合理性、科学性。

UAV flight safety evaluation is an important part of UAV flight management. This paper takes Trimble UX5 aerial UAV as an example. Based on the characteristics of UAV flight, this paper used the Delphi method and literature collection method to identi- fy the risk factors, and the risk index system of UAV flight safety is selected. The rank correlation analysis is used to determine the risk factor of UAV flight safety. Combined with the gray Fuzzy theory, the gray fuzzy comprehensive evaluation model of UAV Flight Safety is constructed. The gray and fuzzy uncertain content is transformed into the value which can be measured accurately so as to provide flight plan for decision-makers. Finally, the evaluation model is applied to the flight safety management of Pingyu County water ecologi- cal civilization city planning, proving the rationality and scientiflealness of the model.
