Multi-UAV Relative Position Control for Real-Time Group Flight
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for controlling the flight of multiple unmanned aerial vehicles (UAVs) lack flexibility in specifying flight paths in real-time and require multiple operation devices, making it difficult to operate multiple UAVs collaboratively.
Innovation Solution
A location processing device and method that selects multiple UAVs to form a flight group, determines their relative location information, and instructs an operation device to control the UAVs, allowing for real-time adjustment of flight paths and locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple operation devices are used to control multiple UAVs, then each UAV can be controlled independently, but the system complexity and difficulty of operation increase significantly
Solution Approach 1:
The patent merges the control functions for multiple UAVs into a single operation device. The controller receives operation signals and distributes them to multiple UAVs, allowing one operator to control multiple vehicles simultaneously through a unified interface rather than requiring separate controllers for each UAV.
Solution Approach 2:
The operation device is designed with universal control capabilities that can manage multiple different UAVs through a single interface. The controller acts as a multi-functional device that can send operation signals to various UAVs, making the operation device adaptable to control different types and numbers of UAVs without requiring specialized equipment for each vehicle.
2Adaptability or versatility
If predetermined flight paths are pre-set, then UAVs can follow established routes, but real-time flexibility in adjusting flight paths is reduced
Solution Approach 1:
The system implements dynamic flight path adjustment where the controller can modify flight paths in real-time based on current conditions. Instead of rigid pre-set routes, the flight paths are adaptable and can be changed during operation, allowing UAVs to respond to changing environmental conditions, obstacles, or mission requirements dynamically.
Solution Approach 2:
The system incorporates feedback mechanisms where the controller receives information about UAV positions and environmental conditions, then adjusts flight paths accordingly. This closed-loop control allows real-time modification of flight paths based on actual flight status and external factors, enabling adaptive route planning without requiring complete pre-setting of all flight parameters.
3Productivity
If multiple UAVs operate independently with predetermined paths, then each UAV maintains its own flight schedule, but collaborative flight and coordinated operations become difficult
Solution Approach 1:
The patent merges the control of multiple UAVs into a unified system where a single controller manages all UAVs in the group. This centralized control approach enables coordinated collaborative flights by allowing the controller to synchronize operations, manage relative positions, and coordinate actions across multiple UAVs simultaneously, reducing the complexity that would arise from multiple independent control systems.
Solution Approach 2:
The controller acts as an intermediary between the operator and multiple UAVs, translating single operation signals into coordinated actions for the entire flight group. This intermediary device manages the complexity of multi-UAV coordination by handling position management, collision avoidance, and synchronized operations, allowing simple operator inputs to produce complex coordinated behaviors across multiple vehicles.
