Drone Landing Control on a Stopped Mobile Platform
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current drone systems for agricultural chemical agent application lack effective safety measures to minimize operational stoppages when intruders enter the automatic travel area, impacting operational efficiency.
Innovation Solution
A drone system that coordinates with a movable body to adjust the drone's landing position based on the movable body's stop position, using demarcating members to detect intruders and control the movable body's movement, while determining optimal landing positions to minimize stoppages and ensure safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the movable body stops movement when an intruder is detected by the demarcating member, then safety is improved, but operational efficiency deteriorates due to operation stoppages
Solution Approach 1:
The system dynamically adjusts the movable body's response based on the drone's state. When the drone is in flight, the movable body stops upon intruder detection to ensure safety. When the drone is on the ground, the movable body continues moving to maintain operational efficiency. This dynamic state-dependent control resolves the contradiction between safety and productivity.
Solution Approach 2:
The system changes the movement parameter of the movable body based on the drone's state parameter. The movement state transitions between 'stop' and 'continue' depending on whether the drone is 'in flight' or 'on ground'. This parameter change approach allows the system to optimize both safety and operational efficiency under different conditions.
2Ease of operation
If the drone lands on the movable body at the original landing position, then operational simplicity is maintained, but operational efficiency deteriorates when the movable body stops due to intruders
Solution Approach 1:
The landing position is dynamically adjusted based on the movable body's stop position. The control section calculates the offset between the original landing position and the movable body's current position, then commands the drone to land at the adjusted position. This dynamic position adjustment maintains operational simplicity while preventing stoppages.
Solution Approach 2:
The system uses feedback from the movable body's position information to adjust the drone's landing position. The control section receives position data from the movable body, calculates the necessary position correction, and commands the drone to land at the corrected position. This feedback mechanism ensures continuous operation without stoppages.
3Productivity
If the drone continues operation without adjusting landing position, then operational efficiency is maintained, but safety deteriorates when the movable body stops due to intruders
Solution Approach 1:
The system dynamically adjusts the landing position based on the movable body's stop position caused by intruder detection. This dynamic adjustment ensures that the drone can safely land on the movable body even when it has stopped, maintaining both safety and operational efficiency simultaneously.
