Communication Path Monitoring for Early Abnormal Section Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques face difficulties in identifying abnormal communication sections before an abnormality occurs and incur high handling costs due to the need for manual operations with devices like OTDR after an abnormality has occurred.
Innovation Solution
A monitoring device that includes an acquisition unit, first and second creation units, and an identification unit to analyze terminal accommodation and configuration information, learn normal states, detect changes, and identify abnormal communication sections using software-based calculations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual operation with OTDR is performed after abnormality occurrence, then abnormality identification can be achieved, but handling cost increases and time is lost
Solution Approach 1:
The patent applies preliminary action by continuously monitoring terminal states and detecting changes before actual abnormalities occur. The system proactively identifies potential issues through early detection of state changes, allowing preventive maintenance before failures happen, thus avoiding the need for reactive OTDR operations after abnormalities occur.
Solution Approach 2:
The monitoring device performs self-service by automatically detecting terminal state changes and identifying abnormal communication sections without requiring manual intervention. The system autonomously processes monitoring data, creates information on terminal changes, and identifies abnormalities, eliminating the need for manual OTDR operations.
2Reliability
If conventional monitoring is performed, then basic communication monitoring is achieved, but early identification of abnormal sections is difficult
Solution Approach 1:
The patent implements feedback by continuously monitoring terminal states and using the detected changes to identify abnormalities. The system feeds back information about terminal state changes to the identification unit, which then determines abnormal communication sections based on the accumulated change information, enabling early detection of issues that would otherwise be difficult to identify.
3Measurement precision
If manual OTDR operation is required, then precise abnormality location is achieved, but handling cost increases
Solution Approach 1:
The patent replaces the mechanical/manual OTDR system with an automated monitoring system that uses software-based analysis of terminal state changes. Instead of manually operating physical measurement devices, the system uses computational methods to process monitoring data and identify abnormalities, reducing handling costs while maintaining or improving detection accuracy.

AI summary
A monitoring device (100) includes an acquisition unit (121), a first creation unit (122), a second creation unit (125), and an identification unit (126). The acquisition unit (121) acquires terminal accommodation information, configuration information, and information regarding terminals. The first creation unit (122) creates information on paths used for communication of the terminals and information on a terminal group in communication sections of the terminals on the basis of the terminal accommodation information and configuration information acquired by the acquisition unit (121). The second creation unit (125) creates information on a change in each terminal on the basis of the information regarding the terminals acquired by the acquisition unit (121). The identification unit (126) identifies an abnormal communication section on the basis of the information on the paths used for communication of the terminals and the information on the terminal group in the communication sections of the terminals, created by the first creation unit (122), and the information on a change in each terminal, created by the second creation unit (125).
