UAV Control Switching Logic for Stable Flight Transitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned aerial vehicles (UAVs) experience stability issues when switching between different control states, such as from autonomous flight to operator-controlled flight or between different wireless operation devices, due to drastic changes in instruction information, leading to unstable flight conditions.
Innovation Solution
An unmanned aerial vehicle control system that includes first and second acquisition means to gather operating information and flight control means to restrict switching based on matching first and second instruction information, ensuring stable transitions by preventing abrupt changes in control states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If switching is allowed between different control states or wireless operation devices, then adaptability and ease of operation are improved, but flight stability deteriorates due to drastic changes in instruction information
Solution Approach 1:
The system performs preliminary comparison of instruction information before allowing switching. The flight management device acquires first instruction information from the first wireless operation device and second instruction information from the second wireless operation device, compares them in advance, and determines whether switching is permitted based on whether they match. This prevents drastic changes that would compromise flight stability while still allowing adaptable switching when conditions are appropriate.
Solution Approach 2:
The system implements a feedback mechanism where the flight management device continuously monitors and compares instruction information from different control sources. Based on the comparison result, it provides feedback by either permitting or prohibiting switching. This closed-loop control ensures that switching only occurs when instruction information is consistent, thereby maintaining flight stability while enabling operational flexibility.
2Stability of the object's composition
If switching is restricted to prevent drastic changes, then flight stability is improved, but ease of operation deteriorates due to limited control transitions
Solution Approach 1:
The system employs self-service by automatically comparing instruction information and determining switching permission without requiring manual intervention or complex operator judgment. The flight management device autonomously acquires, compares, and evaluates instruction information, then permits or prohibits switching based on the comparison result. This automated process maintains flight stability while preserving ease of operation, as operators can attempt switching without concern for stability issues.
3Stability of the object's composition
If instruction information is strictly compared before switching, then flight stability is improved, but device complexity increases due to additional comparison and control logic
Solution Approach 1:
The flight management device performs multiple functions using the same core mechanism: it manages flight control, acquires instruction information from multiple wireless operation devices, compares instruction information, and determines switching permission. By integrating these functions into a single multi-functional system rather than separate dedicated components, the patent reduces overall device complexity while maintaining flight stability through instruction information comparison.

AI summary
To ensure stability of flying by an unmanned aerial vehicle, first acquisition means of an unmanned aerial vehicle control system acquires first information, which is at least one piece of information for operating an unmanned aerial vehicle that is flying or information on a result of detecting an operation of the unmanned aerial vehicle. Second acquisition means acquires second information for operating the unmanned aerial vehicle after switching of control of the unmanned aerial vehicle. Flight control means restricts, in accordance with the first information and the second information, switching to control of the unmanned aerial vehicle based on the second information.
