UAV Route Directing for Dynamic Restricted Area Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of unmanned aerial vehicles (UAVs) poses challenges in ensuring safe traffic management, particularly in preventing collisions and unauthorized entry into restricted areas, such as airports, and protecting personal privacy, as they may fly randomly or breach restricted zones.
Innovation Solution
A method and system that enables UAVs to receive wireless communication from a network entity about restricted areas, allowing them to withdraw and reroute to avoid such zones, using communication modules for real-time updates and virtual road management within a communications system, such as LTE or 5G, to ensure safe and controlled flight paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If UAVs use pre-downloaded maps and static routes, then device complexity is reduced, but adaptability to temporary flight restrictions and dynamic conditions deteriorates
Solution Approach 1:
The patent introduces a network entity as an intermediary between the UAV and the flight restriction data. The network entity receives, stores, and manages restricted area information, then provides it to UAVs upon request. This allows UAVs to access dynamic flight restriction data without carrying complex onboard storage and update mechanisms, resolving the contradiction between adaptability and device complexity.
2Reliability
If UAVs receive real-time route directing from network entity, then safety and adaptability improve, but loss of time in communication and route calculation increases
Solution Approach 1:
The network entity performs preliminary actions by pre-processing restricted area data and preparing route information before the UAV actually needs it. When a UAV requests flight information, the network entity has already organized the restricted area boundaries and can quickly calculate appropriate routes, reducing the real-time processing delay and improving safety response time.
