Power Line Backup for POE Link and Power Redundancy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional backup protection schemes for Ethernet transmission are not conducive to cost saving and green energy saving, as they require two sets of devices for data link and power source backup.
Innovation Solution
A method and system utilizing Active Power over Ethernet (POE) and Broadband over Power Line (BPL) technologies to provide simultaneous data link and power source backup using a single set of devices, where the power line serves as a backup link for Ethernet data transmission and POE technology supplies power, allowing for seamless switching between POE and BPL links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional backup protection scheme is used with two sets of POE devices and transmission links, then reliability of data transmission is improved, but device complexity and cost increase
Solution Approach 1:
The patent merges the backup data transmission link and backup power source into a single power line infrastructure. The power line simultaneously serves as both the backup data transmission medium (via BPL technology) and the backup power source, eliminating the need for separate backup devices and links while maintaining reliability.
Solution Approach 2:
The power line is designed to perform multiple functions: it serves as the primary power source for POE devices, a backup data transmission link through BPL technology when Ethernet fails, and a backup power source through power line power supply when POE fails. This multi-functionality reduces overall system complexity.
2Reliability
If traditional backup protection scheme with two sets of devices is deployed, then backup capability is improved, but energy consumption increases
Solution Approach 1:
By combining backup data transmission and backup power supply functions into the single power line infrastructure, the patent eliminates the need for two separate sets of active devices. Only one set of POE devices needs to remain active, while the power line provides standby capabilities, significantly reducing energy consumption compared to maintaining two full sets of active equipment.
3Ease of manufacture
If power line is used for both power supply and data transmission backup, then cost is reduced, but technical complexity of power line utilization increases
Solution Approach 1:
The power line infrastructure is designed with multi-functionality to handle both power delivery (for POE devices) and data transmission (via BPL technology). By integrating these functions into existing power line infrastructure rather than creating new specialized systems, the patent reduces implementation costs while managing technical complexity through standardized multi-use protocols.
