Drone Light Emission Control for Long-Range Visual Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators face difficulties in visually observing and controlling drones located far from their remote controllers, especially at night or in conditions with poor visibility, due to the limitations of existing drone control systems.
Innovation Solution
A light emission control apparatus and method that utilize a light emitter on the drone to emit light in specific directions based on flight state information, including controller and drone positional data, inclination, and wind direction, allowing the operator to visually track the drone's position and movement even from a distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the drone is located far from the operator, then the operator can control the drone over a larger area, but it becomes difficult for the operator to visually observe the drone
Solution Approach 1:
The patent applies color changes by having the drone emit light in different colors (e.g., green, red, blue) to indicate different flight states such as moving forward, backward, left, right, or hovering. This allows the operator to visually observe and understand the drone's flight state from a distance without needing to be close to the drone.
Solution Approach 2:
The patent introduces light emission as an intermediary signal between the drone and the operator. The light emitter on the drone acts as a mediator that transmits flight state information visually to the operator, enabling observation from a distance without requiring direct visual contact with the drone itself.
2Illumination intensity
If the light emitter continuously emits light to improve visibility, then the operator can easily observe the drone, but power consumption increases
Solution Approach 1:
The patent implements periodic action by having the light emitter emit light only during specific periods when the drone is in flight or when observation is needed, rather than continuously. The light emission is activated based on flight state information, reducing power consumption while maintaining visibility during critical operations.
Solution Approach 2:
The patent applies dynamics by making the light emission dynamic and adaptive to the drone's flight state. The light emitter adjusts its operation based on real-time flight conditions, emitting light when the drone is moving or in states requiring observation, and reducing or stopping emission when the drone is stationary or in safe positions, thereby optimizing power consumption.

AI summary
A drone includes a light emitter that emits light and circuitry which, in operation, obtains flight state information regarding a flight state of the drone, determines, on the basis of the flight state information, a direction in which the light emitter is to emit light, and controls the light emitter such that the light emitter emits light in the determined direction.
