Laser Fiber Connector Fault Detection for Specific Abnormal States
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laser devices cannot individually detect disconnection abnormalities in optical fibers and opening abnormalities in optical connectors, making it difficult to determine the specific abnormal state and set appropriate recovery measures.
Innovation Solution
The laser device incorporates pairs of disconnection detection lines, open detection lines, and temperature detection lines within the optical connector, with a determination portion to differentiate between these abnormalities and trigger specific alarms, allowing for individual detection and appropriate action.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single interlock circuit is used to detect multiple abnormal states, then the device structure is simple, but it is impossible to determine which specific abnormal state has occurred
Solution Approach 1:
The patent divides the detection system into multiple independent detection circuits: a first detection circuit for optical fiber disconnection and a second detection circuit for optical connector opening. Each circuit independently monitors its specific abnormal state, allowing the system to identify which specific abnormality has occurred while maintaining relatively simple overall structure.
2Loss of information
If multiple detection circuits are used to identify specific abnormal states, then abnormal state identification is accurate, but the device structure becomes complex
Solution Approach 1:
The detection system is segmented into specialized sub-circuits, each dedicated to detecting a specific abnormal state. This segmentation allows for accurate identification of abnormalities while keeping each individual detection circuit simple and manageable.
Solution Approach 2:
The patent introduces a determination unit as an intermediary component that receives detection results from multiple detection circuits and processes them to identify the specific abnormal state. This intermediary layer simplifies the overall system architecture by centralizing the decision-making logic.
3Reliability
If the interlock circuit is blocked for any abnormal state, then safety is ensured, but recovery measures cannot be tailored to the specific abnormal state
Solution Approach 1:
The determination unit provides feedback about the specific type of abnormal state detected, enabling the control unit to select and execute appropriate recovery measures tailored to each abnormal state, while still maintaining safety through the interlock mechanism.
Solution Approach 2:
The system dynamically adjusts its response based on the detected abnormal state. Rather than a static interlock response, the system can apply different recovery strategies (such as different threshold adjustments or operational modifications) depending on whether the abnormality is an optical fiber disconnection, optical connector opening, or other condition.
