Unmanned aerial vehicles (UAVs) face inefficiencies in plant-protection operations due to residual pesticide liquids in their tanks, affecting accuracy and operation efficiency, as existing systems lack effective methods for precise liquid volume management.
Innovation Solution
A liquid volume transfer system comprising a liquid infusion device, a liquid container, and an UAV, equipped with communication modules and controllers, which communicate to determine and manage the remaining liquid volume, ensuring accurate infusion and spraying operations by calculating and correcting liquid volumes based on flow rates and weights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the UAV uses its own battery capacity for plant-protection spraying operations, then the UAV can perform autonomous spraying, but the limited battery capacity causes residual pesticide liquid to remain in the tank, affecting infusion accuracy and reducing operation efficiency
Solution Approach 1:
The patent introduces a liquid infusion device as an intermediary system that connects to the UAV's liquid container via a communication module. This external infusion device monitors the remaining liquid volume through the communication module and automatically infuses additional liquid when the volume falls below a threshold, thereby maintaining infusion accuracy without being constrained by the UAV's battery capacity alone
Solution Approach 2:
The system implements a feedback mechanism where the infusion device continuously obtains remaining liquid volume data from the communication module in the liquid container. Based on this feedback information, the infusion device calculates the target infused liquid volume and automatically controls the infusion process to maintain accurate liquid levels, resolving the accuracy issue caused by limited autonomous operation
2Productivity
If the UAV performs continuous spraying operations, then productivity increases, but residual liquid volume management becomes inaccurate, leading to wasted time and reduced efficiency in subsequent operations
Solution Approach 1:
The liquid container's communication module autonomously monitors and reports remaining liquid volume without requiring external intervention. The infusion device automatically processes this information and performs infusion operations when needed, enabling the system to self-manage liquid volume and eliminate time-consuming manual monitoring and intervention
Solution Approach 2:
The system performs preliminary actions by continuously monitoring liquid volume and automatically initiating infusion operations before the liquid is completely depleted. This proactive approach ensures that the liquid container is always ready for the next spraying operation, eliminating idle time and maintaining continuous productivity
