Sub-Drone Wind Sensing for Main Drone Flight and Landing Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drone systems face challenges in reducing environmental influences such as wind direction and speed during flight, as measurement devices are typically fixed and cannot accurately capture varying environmental conditions in real-time, especially at different positions and altitudes.
Innovation Solution
An information processing system comprising a flying object, a control device, and a mobile object (sub-drone) that acquires and transmits environmental information to assist the main drone in flight control, allowing for dynamic adjustment of flight paths and landing procedures based on real-time wind data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a measurement device is disposed at a predetermined fixed position to acquire environmental information, then the device structure is simple and easy to implement, but the environmental information cannot accurately reflect the varying wind conditions at different positions and altitudes
Solution Approach 1:
The patent applies the dynamics principle by making the measurement device mobile rather than fixed. The mobile object (second flying object) moves to different positions and altitudes to acquire environmental information dynamically, allowing the system to capture accurate wind data at multiple locations while managing complexity through automated movement control
Solution Approach 2:
The patent uses a mobile object as an intermediary between the fixed base station and the flying object. This mobile object carries the measurement device and transmits environmental information to both the base station and the flying object, enabling accurate environmental data acquisition without requiring the flying object itself to carry heavy measurement equipment
2Object-affected harmful factors
If environmental information is acquired only at a fixed base station position, then the system is simple to operate, but the environmental influence on the flying object cannot be sufficiently reduced
Solution Approach 1:
The patent applies preliminary action by having the mobile object acquire environmental information in advance at multiple positions and altitudes before the flying object reaches those locations. The base station receives and stores this information, allowing the flying object to proactively adjust its flight path to avoid strong wind areas
Solution Approach 2:
The system implements feedback by continuously transmitting environmental information from the mobile object to the base station and flying object. This real-time feedback enables the flying object to adjust its flight control based on current wind conditions at its location and predicted conditions along its flight path

AI summary
To effectively reduce an influence of an environment in flight (including taking-off and landing) of a flying object. A main drone current position information acquisition unit 131 acquires a current position of a main drone 2 from a main drone control terminal 4 through a communication unit 39, and provides the current position to the movement instruction unit 133. The sub-drone current position information acquisition unit 132 acquires a current position of the sub-drone 1 from the sub-drone 1 through the communication unit 39, and provides the current position to the movement instruction unit 133. The movement instruction unit 133 determines a movement position of the sub-drone 1 on the basis of the current position of the main drone 2. In addition, the movement instruction unit 133 generates a movement instruction for the sub-drone 1 on the basis of a difference between the current position and the movement position of the sub-drone 1, and transmits the movement instruction to the sub-drone 1 through the communication unit 39. The drive control unit 111 acquires the movement instruction transmitted from the sub-drone control terminal 3 through a communication unit 18.
