UAV Spiral Spraying for Variable-Height Fruit Tree Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current UAV plant protection methods for fruit trees are labor-intensive, prone to manual errors, and lack precise spraying due to complex topography and varying tree heights, leading to inefficiencies and increased costs.
Innovation Solution
A UAV operating method that acquires mapping information including safe height, geographic position, and spray radius, allowing the UAV to autonomously adjust its flight height and perform spiral spraying operations based on pre-defined parameters, ensuring precise coverage and efficient pesticide application across varying crop topographies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual and remote control mode is used for spraying fruit trees, then the UAV can be controlled to spray pesticides, but the labor cost is high and full operator participation is required
Solution Approach 1:
The system enables autonomous operation by equipping the UAV with mapping information acquisition, flight height adjustment, and spiral spraying execution capabilities. The UAV automatically navigates to target fruit trees, adjusts its flight height based on tree height data, and performs spiral spraying without continuous manual intervention, thereby reducing labor costs while maintaining spraying effectiveness
Solution Approach 2:
The system performs preliminary acquisition of mapping information including fruit tree locations, heights, and spray radii before the actual spraying operation. This pre-planning allows the UAV to autonomously navigate and execute spraying tasks without real-time manual guidance, improving both ease of operation and productivity
2Ease of operation
If manual control is used for spraying, then the operator can control the UAV, but fruit trees obstruct the operator's sight and increase control difficulty
Solution Approach 1:
The system replaces manual visual control with automated systems including mapping information processing, autonomous navigation, and height adjustment mechanisms. The UAV uses pre-acquired spatial data to locate and spray fruit trees without operator visual intervention, eliminating sight obstruction issues while maintaining or improving spraying accuracy
Solution Approach 2:
The system introduces mapping information and automated control algorithms as intermediaries between the operator and the UAV. Instead of direct visual control, the operator inputs target information and the automated system handles navigation and spraying execution, resolving the visibility obstruction problem while ensuring reliable operation
3Ease of operation
If manual control is used for spraying, then the operator can adjust spray parameters, but it is difficult to control the dose of spray and precise spraying effect is not achieved
Solution Approach 1:
The system automatically adjusts spray parameters including flight height, spray radius, and spiral rotation speed based on pre-acquired mapping information about each fruit tree. This automated parameter optimization ensures consistent and precise spray dosing without manual intervention, achieving uniform coverage and eliminating the imprecision of manual control
Solution Approach 2:
The system uses mapping information about fruit tree locations, heights, and dimensions as feedback to automatically adjust spraying parameters. This closed-loop approach ensures that each tree receives the appropriate spray dose based on its specific characteristics, achieving precise spraying效果 that cannot be reliably obtained through manual control
