UAV Flight Path Control Around Moving 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
A UAV control system that includes moving object position acquisition, zone setting, and flight control mechanisms to dynamically set and navigate around 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 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 no-fly zone is transformed from a static concept based on fixed structures to a dynamic concept that moves and changes shape according to the position and movement state of moving objects. The control unit continuously updates the no-fly zone parameters (position, size, shape) based on real-time moving object position information, enabling the system to adapt to changing conditions while maintaining operational simplicity.
2Reliability
If the UAV avoids all moving objects, then collision safety is improved, but the UAV may become an unnecessary obstacle to moving objects
Solution Approach 1:
Instead of applying a uniform avoidance policy to all moving objects, the system adjusts the no-fly zone characteristics (position, size, shape) locally according to each moving object's specific movement state. The control unit determines appropriate no-fly zone parameters based on whether the moving object is stationary, moving slowly, or moving quickly, thereby providing safety where needed while minimizing unnecessary interference.
3Adaptability or versatility
If the no-fly zone is updated in real-time based on moving object position, then the UAV can avoid changing obstacles, but the system complexity and computational load increase
Solution Approach 1:
The control unit is designed to perform multiple functions: acquiring moving object position information, determining no-fly zone parameters, updating the no-fly zone, and controlling UAV flight path planning. By integrating these functions into a single multi-functional control unit, the system achieves dynamic adaptation to moving objects while avoiding the complexity of separate specialized components for each function.

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.
