UAV Base Station Control for Reliable Flight Supervision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current UAV control systems face challenges in ensuring accurate and reliable control due to interference from other wireless networks, particularly when operating in unlicensed frequency bands like 2.4 GHz.
Innovation Solution
A method and apparatus for controlling a UAV by receiving an access message from the UAV, acquiring target supervision strategy information based on the message, and sending a control instruction to the UAV, ensuring that flight criteria are met. This communication is facilitated through a cellular network to minimize interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If UAV communicates using unlicensed frequency band (2.4 GHz), then communication cost is reduced and accessibility is improved, but communication reliability deteriorates due to interference from other wireless networks
Solution Approach 1:
The patent introduces a base station as an intermediary between the remote controller and UAV. The base station receives control signals from the remote controller and transmits them to the UAV, while the UAV replies to the base station. This intermediary structure allows the use of unlicensed frequency bands for accessibility while the base station manages communication to improve reliability by reducing direct interference exposure.
2Device complexity
If UAV operates in unlicensed frequency band, then device complexity is reduced, but control accuracy deteriorates due to interference from other wireless networks
Solution Approach 1:
The base station serves as a mediator that simplifies the UAV's communication system while improving control accuracy. The UAV only needs to communicate with the base station using relatively simple protocols, while the base station handles the complex task of receiving and processing control instructions from the remote controller, thereby ensuring accurate control despite using unlicensed bands.
Solution Approach 2:
The communication system is segmented into two parts: a simple UAV-end communication module that only needs to exchange basic control signals with the base station, and a more complex base station that handles signal processing and interference management. This segmentation allows the UAV to have low device complexity while achieving high control accuracy through the base station's advanced processing capabilities.
3Ease of operation
If UAV uses unlicensed frequency band for communication, then ease of operation is improved, but supervision capability deteriorates due to inability to effectively monitor UAV flight
Solution Approach 1:
The base station acts as an intermediary that enables effective supervision. All control instructions pass through the base station, which can monitor and record them. The UAV's flight status and control commands are transmitted through the base station, allowing ground control to effectively supervise UAV operations even while using unlicensed frequency bands for easy operation.

AI summary
An Unmanned Aerial Vehicle (UAV) control method and apparatus, a base station and a UAV relate to the technical field of wireless communication. The method can include receiving an access message from a UAV, the access message carrying a type identifier of the UAV, acquiring target supervision strategy information based on the access message, the target supervision strategy information indicating a flight criterion of the UAV, and sending a control instruction to the UAV based on the target supervision strategy information, the UAV being configured to control flight based on the control instruction. A base station, when receiving the access message of the UAV, acquires the target supervision strategy information of the UAV based on the access message and controls flight of the UAV based on the target supervision strategy information, so that it is ensured that flight of the UAV meets a supervision requirement.
