Power Supply System with Detection Controller for ONT Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Optical Network Termination (ONT) devices fail to operate normally when utility power is not supplied correctly, leading to disruptions in information transmission services.
Innovation Solution
A power supply system comprising an adapter and a converter with a detection controller that switches between utility power and auxiliary power sources based on the power supply status, ensuring continuous operation by routing power to the ONT device through external connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the ONT device is coupled to utility power through an adapter for normal operation, then the device can operate normally under standard power supply conditions, but the device fails to operate when utility power is not supplied correctly
Solution Approach 1:
The adapter is designed to accept multiple power source types (utility power and auxiliary power sources like batteries or power banks) through the same interface. The detection controller automatically identifies and adapts to different power source types, enabling the adapter to function universally with various power supplies without requiring separate adapters for different power sources.
Solution Approach 2:
The system dynamically switches between utility power and auxiliary power sources based on real-time detection of power supply status. The detection controller continuously monitors the power input and automatically transitions to alternative power sources when utility power is abnormal, ensuring continuous operation without manual intervention.
2Reliability
If a detection controller is added to switch between power sources, then the system can automatically respond to power supply abnormalities, but the device complexity increases
Solution Approach 1:
The detection controller automatically detects power supply abnormalities and switches between power sources without requiring user intervention. The system performs self-diagnosis and self-correction by monitoring power parameters and autonomously selecting appropriate power sources, eliminating the need for complex manual control mechanisms.
Solution Approach 2:
The detection controller serves as an intermediary between the power input interface and the ONT device. It monitors power supply status and controls the switching between utility power and auxiliary power sources, simplifying the overall system architecture by centralizing the control function in a single component rather than requiring complex distributed control.

AI summary
A power supply system having an adapter and a converter is provided. The adapter includes a first inputting terminal coupled to a first power and a first outputting terminal coupled to a first loading device. The converter includes a detecting controller, a second inputting terminal coupled to the detecting controller, a second outputting terminal, and a third outputting terminal. The second outputting terminal and the third outputting terminal are coupled in parallel to the detecting controller. The third outputting terminal is coupled to the position between the first inputting terminal and the first outputting terminal of the adapter through external connection. The second inputting terminal is coupled to a second power, and a second loading device is coupled to the second outputting terminal. The detecting controller drives the second power supply to the first loading device according to the power supply status of the first power.
