Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing UAV communication mechanisms are non-synchronous, leading to inefficiencies in regulation and potential conflicts when monitoring and broadcasting information from multiple unmanned aerial vehicles.
Innovation Solution
A method and system for broadcasting monitoring information that aligns transmission sessions with a system time, dividing time into segments for different types of UAVs to prevent conflicts, using long and short data packets during specific time slices to reduce bandwidth requirements and crosstalk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If non-synchronous communication mechanisms are used for UAVs, then ease of operation is improved, but collision probability increases and regulation efficiency deteriorates
Solution Approach 1:
The communication system is segmented into multiple transmission sessions divided into first time periods and second time periods, with each period containing multiple time slices. Different types of UAVs are assigned to different time periods, creating a segmented temporal structure that prevents collisions while maintaining ease of operation.
Solution Approach 2:
The patent implements periodic transmission sessions with defined time periods and time slices. UAVs transmit monitoring information periodically according to their assigned time slots, ensuring synchronized communication that reduces collision probability while maintaining operational simplicity.
2Productivity
If multiple UAVs broadcast information simultaneously, then productivity is improved, but harmful factors increase due to signal crosstalk and interference
Solution Approach 1:
The time domain is segmented into first time periods for first types of UAVs and second time periods for second types of UAVs. Each time period is further divided into multiple time slices, allowing multiple UAVs of the same type to transmit sequentially without interference, thus maintaining productivity while eliminating signal crosstalk.
Solution Approach 2:
The system dynamically assigns different time periods to different UAV types based on their characteristics. This dynamic temporal allocation allows the system to accommodate multiple UAVs simultaneously while preventing harmful interference through adaptive time slot management.

AI summary
A monitoring information broadcasting method includes determining a series of transmission sessions aligned to a system time of a mobile platform. Each transmission session includes a first time period and a second time period. The first time period includes a plurality of first time slices and the second time period includes a plurality of second time slices. The method further includes performing one of broadcasting a data packet of a first type during a first active slice among the first time slices in the first time period of one of the transmission sessions or broadcasting a data packet of a second type during a second active slice among the second time slices in the second time period of the one of the transmission sessions.
