Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current UAV control systems are limited by their stand-alone mode, requiring multiple ground stations to control multiple UAVs, and face communication challenges with limited data transmission ranges, leading to issues like communication link interruptions during over-the-horizon flights.
Innovation Solution
A method and system that utilizes a server to receive and process UAV control instructions, identify UAVs via variable and address identifications, and transmit commands through mobile networks (3G/4G), enabling multiple UAVs to be controlled by a single ground station and maintaining communication over long distances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple ground stations are used to control multiple UAVs, then each UAV can be controlled independently, but the system complexity and cost increase
Solution Approach 1:
The patent merges multiple ground station functions into a single ground station by introducing a server that can manage and control multiple UAVs simultaneously. The server consolidates the control capabilities that would otherwise require separate ground stations, reducing system complexity while maintaining the ability to control multiple UAVs independently.
Solution Approach 2:
The server is designed with universal control capabilities that allow it to manage multiple different UAVs through a single interface. The address identification mechanism enables the server to differentiate between various UAVs and send appropriate control instructions, making one ground station system capable of performing the functions of multiple ground stations.
2Adaptability or versatility
If traditional communication systems are used for UAV control, then the system is simple, but the data transmission range is limited causing communication link interruptions during over-the-horizon flights
Solution Approach 1:
The server acts as an intermediary between the ground station and UAVs, enabling long-range communication through mobile networks. Instead of direct line-of-sight communication between ground station and UAV, the server receives control instructions from the ground station and forwards them to UAVs via mobile network infrastructure, extending the communication range beyond traditional limits while maintaining reliability.
3Device complexity
If a single ground station controls multiple UAVs through direct communication, then the system is simple, but communication range is limited
Solution Approach 1:
The server serves as a communication intermediary that enables long-range UAV control while maintaining system simplicity. By routing communications through the server and utilizing mobile network infrastructure, the system achieves extended communication range without requiring complex direct long-range communication hardware between ground station and UAVs.
