Network Node Power Supply Switching for Transmission Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unstable electrical power supply from grids leads to fluctuations in optical signal strength across data transmission links in communication networks, resulting in decreased transmission rates and user experience degradation, as existing manual switching methods are reactive and delayed.
Innovation Solution
A method and apparatus for proactively switching the power supply of network nodes from an electrical grid to an alternative power supply based on predicted signal strength fluctuations, using a power controlling network node that receives information on transmission rate decreases and initiates the switch when the alternative power supply's charge level exceeds a threshold.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual power supply switching is used, then device complexity is reduced, but reliability deteriorates due to reactive and delayed response to power fluctuations
Solution Approach 1:
The system performs preliminary actions by proactively switching the power supply from the electrical grid to the alternative power supply before power fluctuations occur. The network node monitors power quality parameters and initiates the switching action in advance, preventing signal strength drops and transmission rate degradation before they happen, thus resolving the contradiction between simple manual control and reliable transmission.
2Productivity
If alternative power supply is used proactively, then transmission rate stability is improved, but loss of energy increases due to battery discharge
Solution Approach 1:
The system implements feedback control by continuously monitoring both the electrical grid power quality and the alternative power supply charge level. The network node uses this feedback information to make intelligent switching decisions, activating the alternative power supply only when grid power degrades and ensuring the battery has sufficient charge, thus maintaining transmission rate stability while optimizing energy usage and preventing unnecessary battery discharge.

AI summary
Embodiments described herein provided methods and apparatus for controlling switching a power supply of a first network node between an electrical power grid and an alternative power supply in which the first network node is configured to transmit data to a second network node over a data transmission link. The method includes receiving first information indicative of a predicted decrease in a transmission rate of data transmitted by the first network node over the data transmission link. Responsive to receiving the first information, a first request is transmitted to the first network node to switch the power supply of the first network node from the electrical power grid to the alternative power supply.
