Flight Control Apparatus for UAV Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned air vehicles (UAVs) may fail to arrive at designated positions within set time limits, potentially causing collisions with subsequent UAVs or disrupting their flight paths.
Innovation Solution
A flight control system that includes an acquisition unit for flight plans, an arrival judging unit to assess timely arrival, a condition determination unit to adjust flight conditions if the UAV is late, and a flight control unit to switch between primary and secondary flight control methods based on the judgment, allowing for adaptive path changes to avoid collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the air vehicle follows the predetermined flight plan strictly, then the flight path is maintained as planned, but the risk of collision with subsequent air vehicles increases when the air vehicle cannot arrive within the time limit
Solution Approach 1:
The flight control apparatus dynamically adjusts the flight path based on real-time arrival assessments. When the air vehicle is projected to arrive at a position later than the time limit, the system automatically determines an alternative flight path that allows subsequent air vehicles to pass through the original position, thereby adapting the flight plan to current conditions and reducing collision risk.
Solution Approach 2:
The system continuously monitors the air vehicle's position and calculates whether it will arrive at each position within the predetermined time limit. This feedback mechanism triggers automatic flight path adjustments when timing constraints are violated, enabling the system to respond to real-time deviations from the planned schedule.
2Reliability
If the air vehicle changes flight path to avoid collision, then the collision risk with subsequent air vehicles is reduced, but the deviation from the original flight plan increases
Solution Approach 1:
The flight control apparatus performs preliminary assessment of whether the air vehicle will arrive at each position within the time limit before actually reaching that position. This advance evaluation allows the system to proactively adjust the flight path to avoid timing violations and potential collisions, rather than reacting after the fact.
3Productivity
If the air vehicle maintains strict timing constraints, then subsequent air vehicle scheduling is optimized, but the current air vehicle may be forced to take suboptimal flight paths
Solution Approach 1:
The flight plan is segmented into multiple positions with individual time limits. The system evaluates each segment independently to determine whether timing constraints will be met, allowing for localized path adjustments rather than requiring complete flight plan changes. This segmentation enables efficient scheduling while maintaining operational simplicity for each individual segment.

AI summary
A flight control apparatus includes an acquisition unit that acquires a flight plan in which first flight conditions are described, and information that indicates a time limit set with respect to a position on a path along which an air vehicle is to fly. An arrival judging unit judges, based on the acquired information, whether or not the air vehicle has arrived at the position within the time limit. A condition determination unit determines a second flight condition if it is judged that the air vehicle has not arrived at the position within the time limit. A flight control unit controls flight of the air vehicle selectively adopts a first flight control method which follows the first flight conditions or a second flight control method which follows the second flight condition based on a result obtained by the arrival judging unit.
