Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Wi-Fi based communication is used for UAV control, then the system complexity is reduced and ease of operation is improved, but the communication range is limited to 200 meters and reliability deteriorates in areas without base station coverage
Solution Approach 1:
The system segments the communication network into multiple hierarchical levels: ground master devices, relay UAVs, and operating UAVs. This segmentation allows the control network to extend beyond the 200-meter Wi-Fi range by introducing intermediate relay nodes that forward commands and data, thereby maintaining ease of operation while expanding reliability to broader geographical areas.
Solution Approach 2:
Relay UAVs serve as intermediaries between the ground master device and distant operating UAVs. These intermediary nodes receive control instructions from the ground master device and transmit them to target UAVs beyond direct Wi-Fi range, resolving the contradiction by enabling extended communication without increasing ground-based system complexity.
2Area of stationary object
If the control range of UAVs is extended beyond 200 meters using relay nodes, then the area of operation is expanded, but the device complexity increases due to multiple connection management requirements
Solution Approach 1:
The system design allows ground master devices and relay UAVs to perform multiple functions: they can act as both Wi-Fi access points for direct connections and as relay nodes for extended range communications. This multi-functionality enables area expansion without proportionally increasing device complexity, as existing devices adapt to different roles based on operational needs.
Solution Approach 2:
The communication architecture implements a nested structure where operating UAVs are nested within the coverage area of relay UAVs, which in turn are nested within the control range of the ground master device. This hierarchical nesting allows systematic expansion of operational area while managing complexity through structured, layered connection protocols.
3Adaptability or versatility
If multiple UAVs are managed within an extended control area, then the versatility of the system is improved, but the difficulty of detecting and measuring UAV positions increases
Solution Approach 1:
The system implements feedback mechanisms where each UAV continuously reports its spatial position information to the network, and relay nodes forward this data to the ground master device. This feedback loop enables the ground controller to maintain accurate awareness of multiple UAV positions across extended areas, supporting system versatility while managing detection complexity through automated position reporting and forwarding protocols.

AI summary
An unmanned aerial vehicle control method and device, and a storage medium. The method comprises: when a first beacon frame sent by a sender is scanned, feeding a first access request back to the sender; sending a second beacon frame to detect whether a first unmanned aerial vehicle which feeds back a second access request according to the second beacon frame exists; if the first unmanned aerial vehicle exists, feeding back confirmation information according to the second beacon frame; and upon receipt of an action instruction sent by the sender, sending the action instruction to the first unmanned aerial vehicle.
