UAV Target Position Sharing for Coordinated Multi-Drone Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned vehicles lack the ability to share target object information effectively, limiting their cooperative operations and intelligence in scenarios like search and rescue, where multiple vehicles need to coordinate their efforts to locate and observe a target.
Innovation Solution
A control method that involves obtaining sensing data from observation sensors on movable platforms, determining the position of a target object, and sending this information to other movable platforms or relay devices to enable coordinated adjustments in the photographing direction of other vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple unmanned vehicles operate independently to search for a target, then each vehicle can autonomously perform sensing and measurement operations, but the target object information cannot be shared with other vehicles, resulting in low cooperative operation intelligence
Solution Approach 1:
The patent introduces a server as an intermediary device that receives sensing data from multiple unmanned vehicles, processes target object information, and distributes it to other vehicles. This mediator enables information sharing without requiring direct complex communication between all vehicle pairs, thus reducing overall system complexity while preventing information loss.
Solution Approach 2:
The server performs multiple functions: collecting sensing data from various vehicles, determining target object positions, managing information distribution, and coordinating vehicle operations. This multi-functional approach consolidates what would otherwise require separate systems, achieving information sharing without proportionally increasing device complexity.
2Adaptability or versatility
If unmanned vehicles share target object information through a centralized server, then cooperative operation intelligence is improved, but the system complexity and communication overhead increase
Solution Approach 1:
The server acts as a centralized intermediary that simplifies communication architecture. Instead of requiring mesh communication between all vehicle pairs (which would create N*(N-1)/2 communication channels), the server provides a single hub for information exchange, reducing communication system complexity while enabling versatile cooperative operations.
Solution Approach 2:
The patent combines multiple communication functions (sensing data transmission, target position reporting, coordination signaling) into a unified server-based communication system. This merging consolidates what would otherwise be separate communication channels, reducing overall system complexity while maintaining adaptability for various cooperative scenarios.
3Productivity
If each unmanned vehicle independently determines target positions, then measurement autonomy is maintained, but the overall search efficiency and coordination between vehicles is reduced
Solution Approach 1:
The server implements a feedback mechanism where it collects target object position information from one vehicle and immediately distributes this information to other vehicles. This feedback loop enables all vehicles to adjust their search patterns based on shared information, significantly improving search efficiency and reducing the time required to locate targets compared to independent operations.
Solution Approach 2:
The server performs preliminary processing of sensing data to determine target object positions before distributing this information to other vehicles. By pre-processing and preparing the target location information centrally, the system enables vehicles to immediately execute coordinated search actions without each vehicle needing to independently process and discover the target, thus reducing overall target location time.

AI summary
A control method includes obtaining sensing data output by an observation sensor of a movable platform when sensing a target object in an environment, determining a position of the target object based on the sensing data, and sending the position of the target object to another movable platform moving in the environment, or to a relay device for the relay device to send the position of the target object to the another movable platform.
