Sub-Drone Wind Sensing for Main Drone Flight Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies struggle to effectively reduce environmental influences, such as wind, on flying objects like drones, as they rely on fixed-position measurement devices that do not account for varying wind conditions at different positions and altitudes during flight.
Innovation Solution
A system utilizing mobile sub-drones that move in conjunction with a main drone to acquire real-time environmental information, such as wind direction and speed, and transmit this data to the main drone for precise flight control, reducing environmental influences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fixed-position measurement device is used to acquire environmental information, then the measurement system is simple and stable, but the environmental information does not reflect the actual conditions at different positions and altitudes during flight
Solution Approach 1:
The patent applies the dynamics principle by transitioning from a fixed-position measurement device to a mobile measurement device (second flying object) that can dynamically reposition itself. The second flying object moves to different locations and altitudes to acquire environmental information that reflects actual flight conditions at various positions, thereby improving measurement precision while managing system complexity through automated movement control.
Solution Approach 2:
The patent introduces a second flying object as an intermediary measurement platform between the ground-based fixed measurement system and the main flying object. This intermediary mobile device captures environmental data from multiple positions and transmits it to the main flying object, serving as a bridge that provides accurate, position-specific environmental information without requiring the main flying object to carry its own measurement device.
2Reliability
If environmental information from a fixed base station is used, then the system is easy to operate, but it cannot sufficiently reduce environmental influence during flight due to position and height variations
Solution Approach 1:
The system improves flight control reliability by dynamically positioning the measurement device (second flying object) to match the main flying object's location and altitude. This dynamic adaptation ensures that environmental information accurately reflects actual flight conditions, enabling more reliable flight control decisions despite the increased operational complexity of coordinating multiple flying objects.
Solution Approach 2:
The patent implements a feedback mechanism where the second flying object continuously monitors environmental conditions and transmits this information back to the main flying object's control device. This real-time feedback loop allows the main flying object to adjust its flight path and operations based on current environmental conditions, thereby improving flight control reliability while the automated nature of the feedback process minimizes the operational burden.
3Reliability
If a mobile object is deployed to acquire real-time environmental information, then environmental influence is reduced, but the system complexity and cost increase
Solution Approach 1:
The second flying object serves multiple functions: it acts as both a measurement platform for environmental information and a communication relay. By making the measurement device multi-functional, the system improves flight safety through accurate environmental data while reducing overall system complexity by eliminating the need for separate dedicated components.
Solution Approach 2:
The patent uses a simplified version or copy of the flying object structure for the measurement device rather than deploying a fully-equipped duplicate. The second flying object carries only the necessary measurement instruments and communication equipment, functioning as a lightweight copy that provides essential environmental data without duplicating the full complexity of a complete flying object system.

AI summary
To reduce environmental influence in flight (including taking-off and landing) of a flying object, main drone current position information acquisition unit acquires a current position of a main drone from a main drone control terminal, and provides the current position to the movement instruction unit. The sub-drone current position information acquisition unit acquires a current position from the sub-drone, and provides it to the movement instruction unit. The movement instruction unit determines a movement position of the sub-drone on the basis of the current position of the main drone. In addition, the movement instruction unit generates a movement instruction for the sub-drone based on a difference between the current position and the movement position of the sub-drone, and transmits the movement instruction to the sub-drone. The drive control unit acquires the movement instruction transmitted from the sub-drone control terminal.
