Passive RFID Chassis Node Identifier for Line Module Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In chassis-based telecommunication networks, replacing network line modules can cause network interruptions due to changes in network node identifiers, leading to communication issues and maintenance challenges.
Innovation Solution
A passive RFID device is used to store network node identifiers, allowing different network line modules to reuse the same identifier, reducing interruption time and simplifying maintenance by eliminating the need for active components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If network line modules are replaced in chassis-based systems, then maintenance and upgrades can be performed without re-wiring, but network interruptions occur due to changes in network node identifiers
Solution Approach 1:
A passive RFID device is introduced as an intermediary component that stores the network node identifier separately from the network line modules. The RFID device remains固定在 the chassis while modules are replaceable, allowing modules to obtain the correct identifier through RFID communication without hard-coding, thus maintaining communication continuity during replacements
Solution Approach 2:
The system is segmented into two independent parts: the chassis with the persistent RFID device containing the network node identifier, and the replaceable network line modules that can be swapped without affecting the identifier storage. This segmentation allows module replacement while preserving the network identity
2Adaptability or versatility
If network line modules have hard-coded identifiers, then each module has a unique identity, but replacement causes network communication issues due to identifier changes
Solution Approach 1:
Instead of each module having its own hard-coded identifier, the system uses a single master identifier stored in the RFID device that is copied or referenced by multiple modules. When modules are replaced, they automatically obtain the correct identifier through RFID communication, eliminating the need for reconfiguration
Solution Approach 2:
The passive RFID device serves as a universal identifier storage that can serve multiple network line modules throughout their operational lifecycle. The same RFID device and identifier can support different modules in different slots, making the identifier assignment universal rather than module-specific
3Ease of manufacture
If active components are used to store network identifiers, then data can be actively managed and updated, but equipment failures increase and maintenance costs rise
Solution Approach 1:
The patent uses passive RFID devices which are simpler, more reliable, and less expensive than active storage components. Passive RFID devices have no power requirements, no moving parts, and extremely long operational lifetimes, making them ideal for storing critical network identifiers without introducing failure points
Solution Approach 2:
The passive RFID device automatically provides identifier information to network line modules through RFID communication without requiring active management, power, or intervention. The system self-configures when modules are inserted, with the RFID device passively responding to reader queries and providing the necessary identifier data
