Smart ODN Port Query Unit for Low Power Consumption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical distribution network (ODN) management systems face challenges with high power consumption, especially in mobile power supply scenarios, leading to short battery life and inefficient operation due to the need for continuous power to query wiring ports, making maintenance and management difficult in complex networks like FTTH systems.
Innovation Solution
The integration of a Port Query Unit (PQU) and Port Management Unit (PMU) in the smart ODN system, where the PQU independently performs queries and activates the PMU only when port changes are detected, allowing the system to operate in low power sleep mode most of the time, reducing overall power consumption and extending battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If all wiring interface management boards are provided with continuous power for querying wiring ports, then the system can promptly respond to port changes, but the power consumption increases and battery life decreases
Solution Approach 1:
The patent implements dynamic power management by transitioning wiring interface management boards between wake and sleep modes based on operational needs. The master control management board can dynamically wake specific boards for query operations and then return them to sleep mode, optimizing the balance between response speed and power consumption.
Solution Approach 2:
The system employs periodic query operations instead of continuous monitoring. The master control management board periodically wakes wiring interface management boards to perform necessary queries and then returns them to sleep mode, reducing overall power consumption while maintaining system responsiveness.
2Ease of operation
If a mobile power supply is used to provide power for wiring operations, then the system becomes portable and easier to operate, but the battery life is limited due to continuous power requirements
Solution Approach 1:
The patent implements periodic operation cycles where wiring interface management boards alternate between active query periods and sleep periods. This reduces the average power consumption from the mobile power supply, thereby extending battery life while maintaining portability.
Solution Approach 2:
The system dynamically adjusts power consumption by transitioning components between active and sleep states based on operational requirements. This dynamic power management extends the duration the mobile power supply can operate, enhancing field deployability.
3Measurement precision
If the system queries all wiring ports continuously to ensure prompt response to changes, then monitoring accuracy is improved, but power consumption increases
Solution Approach 1:
The system performs periodic queries of wiring ports instead of continuous monitoring. The master control management board wakes wiring interface management boards at intervals to check port status, maintaining monitoring accuracy while significantly reducing power consumption during idle periods.
Solution Approach 2:
The wiring interface management boards can autonomously transition to sleep mode after completing their query function, and can be awakened by the master control management board when needed. This self-service mechanism reduces the need for continuous power supply while maintaining monitoring capability.
