Communication Control for Dynamic Free-Space Optical Backup Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems using optical fibers lack the ability to dynamically and suitably select a path for free-space optical communication to backup optical fiber communication, as they often fix a backup path through another slave station apparatus.
Innovation Solution
A communication control system that includes a processor to specify, obtain, and select a path for free-space optical communication based on communication statuses, capacities, and processing capacities of free-space optical communication apparatuses, allowing flexible backup path selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed backup path through another slave station apparatus is used, then communication backup is achieved, but path selection flexibility is lost
Solution Approach 1:
The patent implements dynamic path selection for free-space optical communication by allowing the system to adaptively choose communication paths based on real-time conditions. The master station apparatus can dynamically select among multiple slave station apparatuses as backup paths, transforming the static fixed-path approach into a dynamic adaptable system that responds to changing communication needs and environmental conditions.
Solution Approach 2:
The system changes the parameter of path selection from fixed to variable by considering multiple factors such as communication status, capacity, and processing capabilities of different slave station apparatuses. This allows the backup path to be optimized based on current system state, enabling flexible adaptation while maintaining reliable communication backup.
2Reliability
If multiple free-space optical communication apparatuses are used for backup, then communication reliability is improved, but system complexity increases
Solution Approach 1:
The master station apparatus serves multiple functions: it manages both primary optical fiber communication and backup free-space optical communication, and can select among multiple slave station apparatuses. This multi-functional approach consolidates control in the master station, reducing overall system complexity while maintaining the reliability benefits of multiple backup paths.
Solution Approach 2:
The system obtains communication statuses, capacities, and processing capabilities of free-space optical communication apparatuses to make informed path selection decisions. This feedback mechanism enables intelligent automation of the backup selection process, reducing the operational complexity of managing multiple communication apparatuses while ensuring reliable backup communication.
