UAV Flight Restriction Zone Control Near Airports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack effective methods for controlling the flight of unmanned aerial vehicles (UAVs) in proximity to flight-restricted regions, such as airports, to prevent unauthorized access and ensure safety.
Innovation Solution
The system determines the relative location of a UAV with respect to flight-restricted regions by calculating distances and generating flight restriction zones. Based on this information, the system implements flight response measures, such as landing the UAV, providing a time to land, or sending alerts to operators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flight restriction zones are implemented to prevent UAVs from entering restricted areas, then safety and compliance are improved, but the complexity of the flight control system increases
Solution Approach 1:
The system pre-defines flight restriction zones with geographic boundaries and stores them in a database before flight operations. During flight, the UAV simply checks its current location against these pre-established zones rather than performing complex real-time analysis, thereby ensuring safety while maintaining system simplicity
Solution Approach 2:
A geographic information system (GIS) database serves as an intermediary between the UAV's location data and the flight control logic. The database stores pre-processed restriction zone information, allowing the control system to make compliance decisions through simple database queries rather than complex geometric calculations
2Adaptability or versatility
If the system provides multiple flight response options (land immediately, land after time period, alert operator), then adaptability is improved, but the complexity of decision-making logic increases
Solution Approach 1:
Different flight responses are assigned to different proximity levels relative to restriction zones. The system creates multiple buffered zones at varying distances from restriction boundaries, with each buffer zone having a specific response type (alert, warning, forced landing). This allows adaptability through spatial differentiation rather than complex decision logic
Solution Approach 2:
The system uses distance parameters (buffer zone radii) to determine appropriate flight responses. By changing the proximity parameter, the system automatically selects different response actions without requiring complex decision-making algorithms. The response is determined by which distance threshold the UAV currently satisfies
3Measurement precision
If the system calculates real-time distance between UAV and restriction zones, then measurement precision is improved, but the use of computational resources increases
Solution Approach 1:
The system pre-calculates and stores the geographic coordinates and boundary definitions of all flight restriction zones in a database before flight operations. During flight, the UAV retrieves these pre-stored zone definitions and performs simple distance calculations against its current GPS position, achieving precise measurement without heavy real-time computational processing
Solution Approach 2:
The system creates simplified geometric representations (copies) of complex restriction zone boundaries as polygons with vertices stored in the database. These copied geometric models allow for efficient real-time distance calculations using standard computational geometry algorithms, balancing precision with computational efficiency

AI summary
A flight control apparatus includes one or more memories individually or collectively storing computer program instructions, and one or more processors individually or collectively configured to execute the computer program instructions to: obtain a location of a movable object, obtain a location of a flight restriction zone, and control the movable object to take one or more flight response measures based on the location of the movable object and the location of the flight restriction zone. The flight restriction zone includes a flight restriction strip defined by an area encompassed by a first circle, a second circle, and one or more lines connected to the first circle and the second circle.
