Research on long endurance UAV system design and multinetwork converged communication technology in emergency scenario

To address challenges in emergency scenarios such as low inspection efficiency and slow response of multi-rotor UAVs, this paper proposes a multi-factor-constrained vertical takeoff fixed-wing long-endurance UAV inspection system. The design and optimization focus on UAV configuration and aerodynamic characteristics, while developing payload equipment with built-in target detection and tracking algorithms. Additionally, to meet communication demands for long-distance inspections, the study investigates converged communication technology. This creates a unified communication unit that combines TianTong satellite signals, Beidou short message service, and 4G public networks, significantly enhancing the emergency inspection response capability of UAVs.
