Solution Overview
Problem
Traditional UAV landing methods require high operational capability and manual control, making them complex, inconvenient, and prone to dust generation and ground contamination, with users needing to bend over to retrieve the UAV after landing.
Innovation Solution
A UAV landing control device and method that includes a trigger command receiving module, monitoring module, and rotor control module, allowing the UAV to autonomously determine when to stop rotation based on monitoring information from sensors like distance, image, and velocity sensors for safe and controlled landing on various platforms, including user's hands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual control method is used for UAV landing, then the UAV can land safely with proper attitude control, but the operation process becomes complex and requires high user operational capability
Solution Approach 1:
The UAV performs self-landing by autonomously controlling its own attitude and rotation based on monitoring information from sensors. The system monitors the landing platform, determines landing timing automatically, and controls rotor rotation without requiring manual intervention, allowing the UAV to serve itself during the landing process
Solution Approach 2:
The system continuously monitors the landing platform and environmental conditions using sensors, and uses this feedback information to automatically adjust the landing process. The monitoring module provides real-time data about the platform position and characteristics, which the control system uses to determine the optimal landing timing and control rotor deceleration accordingly
2Reliability
If manual control method is used for UAV landing, then the UAV can be precisely controlled, but the degree of intelligence is low and user participation is required throughout the process
Solution Approach 1:
The UAV autonomously monitors the landing platform and determines the optimal landing timing without user intervention. The system automatically processes monitoring information, makes landing decisions, and executes the landing sequence, demonstrating high-level automation and intelligence
Solution Approach 2:
The patent replaces manual mechanical control with an automated electronic control system. The monitoring module and control module use electronic sensors and processors to detect platform conditions and automatically adjust rotor speeds, substituting human-operated mechanical controls with intelligent electronic systems
3Ease of operation
If UAV lands on the ground using traditional method, then the landing is simple, but dust is raised and ground contamination occurs
Solution Approach 1:
The patent introduces a landing platform as an intermediary between the UAV and the ground. The platform serves as a buffer that absorbs the impact and prevents direct contact between the rotating rotors and the ground, thereby eliminating dust generation and ground contamination while maintaining landing simplicity
4Productivity
If UAV lands on the ground using traditional method, then the landing process is straightforward, but the user has to bend over to pick up the UAV adding retrieval steps
Solution Approach 1:
The landing platform acts as an intermediary that brings the UAV to the user's convenient height. By placing the platform at an elevated position, the UAV lands at a height that eliminates the need for the user to bend over, adding convenience to the retrieval process while maintaining fast landing speed

AI summary
An unmanned aerial vehicle (UAV), a UAV landing control device and method. The UAV landing control method includes: receiving a trigger command; starting to monitor under control of the trigger command and outputting monitoring information based on a landing platform below the UAV, where the UAV has one or more rotors; and determining whether to control the one or more rotors of the UAV to stop rotation based on the monitoring information.
