摘要
近年来,城市场景下的无人机短距物流运输发展迅速,随之而来的城市空域规划问题引起广泛关注。选择无人机航线汇集的航线交叉口作为研究对象,首先分析了航线交叉口的设计影响因素与当前研究现状,接着选取其中的受控平面交叉口进行研究,引入地面“信号灯”策略加以优化。针对平面交叉口和无人机的运行特点,提出了无人机航线通用交叉口模型、信号灯优化控制策略。在杭州华正无人机起降场的真实环境中,仿真验证了本文提出的控制策略可以在保证通行能力的情况下,降低平均延误。研究结果对未来无人机航线交叉口设计和控制具有重要的指导意义。
In recent years,the rapid development of unmanned aerial vehicle short distance logistics transportation in urban scenarios has led to widespread attention to urban airspace planning issues.Route intersections where unmanned aerial vehicle routes converge was selected as the research object.Firstly,the design influencing factors and current research status of route intersections were analyzed.Then,controlled level crossings were selected for research,and the ground“signal lamp”strategy was introduced for optimization.Based on the operational characteristics of level crossings and unmanned aerial vehicles,a universal intersection model was proposed for unmanned aerial vehicle routes and an optimized control strategy for signal lamp.In the real environment of Hangzhou Huazheng UAV takeoff and landing site,simulation has verified that the control strategy proposed can reduce average delay while ensuring traffic capacity.Results have important guiding significance for the design and control of future unmanned aerial vehicle route intersections.
