Mobile Platform Frequency Selection for Multi-UAV Interference Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multiple mobile platforms, such as UAVs, interfere with each other during data transmission, leading to low efficiency and poor experience due to limited available frequency bands for communication.
Innovation Solution
A communication control method and device that determines the quantity of nearby mobile platforms by analyzing broadcast signals, allowing each platform to select an appropriate frequency band for transmission based on this information to avoid interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple mobile platforms transmit data simultaneously using available frequency bands, then data transmission capacity increases, but interference between platforms occurs and transmission efficiency decreases
Solution Approach 1:
The patent dynamically changes the frequency band parameter based on the detected quantity of in-range platforms. When the platform quantity exceeds a threshold, the system switches from a first frequency band to a second frequency band, thereby adapting the transmission parameters to current environmental conditions and reducing interference.
Solution Approach 2:
The system implements a feedback mechanism by continuously detecting broadcast signals from other platforms, determining the in-range platform quantity, and using this information to adjust frequency band selection. This closed-loop control ensures that transmission parameters are continuously optimized based on real-time platform density.
2Reliability
If a fixed frequency band is used for communication, then communication stability is maintained, but frequency band conflicts occur when multiple platforms operate in the same area
Solution Approach 1:
The patent transforms the static frequency band selection into a dynamic process. The frequency band is no longer fixed but changes dynamically based on the detected platform quantity. The system can switch between first and second frequency bands according to real-time conditions, making the communication system both stable through protocol adherence and adaptable through parameter changes.

AI summary
A communication control method includes, in response to communication between a first mobile platform and a first controller via a first communication link, obtaining one or more broadcast signals received by the first mobile platform within a predetermined time range, determining an in-range platform quantity of the second mobile platforms present in a predetermined range of the first mobile platform according to signal information of each of the one or more broadcast signals, and determining a strategy for selecting a frequency to be used by the first mobile platform when communicating with the first controller via the first communication link according to the in-range platform quantity. The one or more broadcast signals are sent by a second mobile platform.
