Parallel Cable Fault Detection via Dual Module Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for parallel cable fault detection in multiple rack configurations fail to accurately locate faulty cables, leading to delayed identification and rectification, as only one rack raises an alarm when a parallel cable between two racks is faulty.
Innovation Solution
The apparatus includes a first detecting module with a resistor and voltage change detection circuit connected to a power supply, and a second detecting module with a resistor and fault detection point connected to ground, both modules controlling their respective fault detection points to change state when a fault occurs, allowing both racks to detect the fault simultaneously and trigger an alarm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single fault detection circuit is used in prior art, then the system can detect faults, but the faulty parallel cable cannot be located quickly and accurately
Solution Approach 1:
The patent divides the fault detection function into multiple independent detection modules, with each module responsible for a specific parallel cable connection. Each rack equipped with multiple parallel cable connectors has corresponding detection modules that independently monitor each cable, enabling precise identification of which specific cable is faulty rather than just detecting that a fault exists somewhere in the system.
2Adaptability or versatility
If multiple parallel cable connectors are set on one rack, then the rack can run in parallel with multiple racks, but the faulty cable cannot be quickly located when a fault occurs
Solution Approach 1:
Each parallel cable connector is assigned a dedicated detection module, segmenting the detection system to match the segmented cable connections. This one-to-one correspondence between connectors and detection modules allows each cable's status to be independently monitored and identified, making fault localization straightforward even when multiple cables are in use.
Solution Approach 2:
The detection modules provide real-time feedback signals that indicate the status of each parallel cable connection. When a fault occurs, the feedback mechanism immediately identifies which specific cable connector is affected, enabling rapid response and maintenance without manual inspection of multiple cables.
