UAV Geo-Fence Approval Control for Restricted Flight and Shooting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing use of drones poses challenges in managing flight safety and privacy, particularly around key facilities, due to the higher accident probability compared to manned aircraft, necessitating advanced autonomous control and restricted area management technologies.
Innovation Solution
An unmanned aerial vehicle (UAV) system that includes a geo-fence area information storage, a controller to manage flight and shooting modes based on approval information, and encryption mechanisms to secure data transmission, ensuring safe operations and privacy protection by prohibiting unauthorized flights and image capture within restricted areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If drones are allowed to fly freely in licensed regions, then operational flexibility and ease of operation are improved, but safety risks and privacy invasion risks increase
Solution Approach 1:
The patent implements pre-flight approval mechanisms where drones must obtain authorization before entering restricted areas. The system pre-identifies geo-fenced zones and requires advance permission requests, preventing unauthorized flights before they occur. This preliminary control layer maintains operational flexibility for authorized flights while blocking unsafe ones in advance.
Solution Approach 2:
The patent introduces an intermediary approval system that acts as a mediator between the drone operator and restricted areas. This intermediary layer verifies flight requests against safety criteria, privacy protection rules, and regulatory requirements before granting access to geo-fenced zones, thus resolving the conflict between operational freedom and safety constraints.
2Reliability
If autonomous control technology is implemented, then accident reduction and safety are improved, but device complexity increases
Solution Approach 1:
The patent segments autonomous control functions into modular components: geo-fence management module, approval request module, encryption module, and flight control module. Each module handles specific safety tasks independently, making the complex autonomous system more manageable and maintainable while achieving comprehensive safety monitoring and accident prevention.
Solution Approach 2:
The patent implements self-service autonomous control where the drone automatically monitors its own position, evaluates flight safety, and makes control decisions without constant human intervention. The system self-manages approval requests, automatically adjusts flight paths to avoid restricted zones, and encrypts transmitted data, reducing operational complexity over time as the system learns and adapts.
3Object-affected harmful factors
If encryption mechanisms are added to secure data transmission, then privacy protection is improved, but device complexity and processing overhead increase
Solution Approach 1:
The patent extracts encryption and decryption operations from the main flight control processing path, handling data security separately from flight management. This separation allows encryption to occur in dedicated security modules without interfering with real-time flight control operations, minimizing processing overhead while maintaining strong privacy protection for transmitted data.
