UAV Control Using Moving-Object No-Fly Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing unmanned aerial vehicle (UAV) control systems fail to effectively avoid no-fly zones that change with the movement of objects like humans and trains, potentially causing collisions or interference.
Innovation Solution
An UAV control system that includes moving object position acquisition, zone setting, and flight control mechanisms to dynamically set and avoid no-fly zones based on the current position and movement of moving objects, using GPS and sensor data to adjust flight paths in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no-fly zones are set based on fixed structures only, then the system is simple to operate, but the UAV may collide with moving objects or become an obstacle to them
Solution Approach 1:
The patent applies dynamics by transitioning from static no-fly zone definitions based on fixed structures to dynamic no-fly zone definitions that track moving objects. The system continuously updates no-fly zone positions based on real-time location data from moving objects, enabling the UAV to adapt its flight path dynamically to avoid collisions with moving entities while maintaining operational simplicity through automated tracking.
2Reliability
If the system tracks moving objects to set no-fly zones, then collision avoidance improves, but the device complexity increases
Solution Approach 1:
The patent implements universality by designing a tracking system that can handle multiple types of moving objects (humans, trains, and other vehicles) through a single unified mechanism. The system uses general-purpose location acquisition technology that works across different object types, reducing overall system complexity while maintaining comprehensive collision avoidance capabilities.
Solution Approach 2:
The system applies self-service by having moving objects automatically provide their own location information through equipped terminals or devices. This eliminates the need for complex external tracking infrastructure, as the moving objects themselves serve as the source of tracking data, simplifying the overall system architecture while improving reliability.
3Measurement precision
If real-time position acquisition is implemented, then the no-fly zone accuracy improves, but the energy consumption increases
Solution Approach 1:
The patent applies periodic action by implementing intermittent position acquisition rather than continuous tracking. The system acquires position data at regular intervals or triggered by significant position changes, maintaining sufficient no-fly zone accuracy while significantly reducing energy consumption compared to continuous real-time tracking. This periodic update mechanism balances precision requirements with energy efficiency.

AI summary
An unmanned aerial vehicle is caused to fly by avoiding a no-fly zone, which changes as a moving object moves. Provided is an unmanned aerial vehicle control system, including: moving object position acquisition means for acquiring moving object position information on a current position of a moving object moving above a surface of an earth; zone setting means for setting a no-fly zone in which a flight of an unmanned aerial vehicle is inhibited based on the moving object position information; and flight control means for controlling the flight of the unmanned aerial vehicle so that the unmanned aerial vehicle avoids the no-fly zone set based on the moving object position information.
