Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional network control methods struggle with accurately identifying line faults due to complex alarm propagation and require manual intervention, leading to inefficiencies and increased costs.
Innovation Solution
A method and system that generate network device vectors for each end of a line, setting communication states based on fault alarms, and determine the line's state through logical operations on these vectors, enabling real-time fault detection and automated recovery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional network control method is used to identify line faults by analyzing alarms from various domains, then fault detection capability is provided, but identification time and operational overhead increase significantly
Solution Approach 1:
The patent segments the network alarm system into domain-specific alarm collecting units that independently collect and analyze alarms within their respective domains. Each unit processes alarm information locally before sharing results, avoiding the need for centralized analysis of all alarms across all domains. This segmentation reduces the time required to identify line faults while maintaining comprehensive fault detection capability.
2Measurement precision
If comprehensive alarm analysis across multiple domains is performed to accurately identify line faults, then detection precision is improved, but system complexity and operational overhead increase
Solution Approach 1:
The patent introduces an intermediary mechanism where domain-specific alarm collecting units act as intermediaries between the complex multi-domain alarm system and the fault identification process. Each intermediary unit processes and filters alarms within its domain, presenting only relevant information to the overall fault analysis system. This reduces system complexity while maintaining the ability to accurately identify faults through coordinated analysis across domains.
3Measurement precision
If manual intervention and expert consultation are used to analyze alarm causal relationships, then fault identification accuracy is improved, but operational costs and time consumption increase
Solution Approach 1:
The patent implements self-service through automated alarm collecting units in each domain that independently perform alarm analysis and fault identification without requiring manual intervention. The units automatically share alarm information and coordinate to identify line faults, eliminating the need for expert consultation and manual causal relationship analysis. This maintains high fault identification accuracy while significantly improving network control efficiency and reducing operational costs.

AI summary
A method and system for line fault detection, and a network control system are provided. A line fault detection method of a line fault detection system operated by at least one processor comprises generating a network device vector for each node, whose elements are network devices included in each node connected to both ends of a line, when a fault alarm occurs, setting an element corresponding to the network device in which the fault alarm occurs among the elements of the network device vector as a communication state according to the fault alarm, and determining whether a fault occurred in the line and the network device where the fault occurred based on the communication state set in the network device vector.
