Terminal Log Analysis and Self-Recovery for Remote Fault Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fault analysis and recovery systems in remotely monitored systems face challenges in detecting anomalies that require communication with a management device, leading to increased man-hours and bandwidth usage, and are unable to address issues like outdated firmware without direct management device intervention.
Innovation Solution
A communication system where terminals and a management device collaborate for fault analysis, with terminals performing self-analysis and self-recovery, and the management device providing coordinated recovery orders to prevent redundant processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the management device collects log information from terminals to perform fault analysis, then fault detection capability is improved, but bandwidth usage and communication costs increase
Solution Approach 1:
The fault analysis function is segmented between terminals and management device. Terminals perform self-diagnosis using locally stored log information, while the management device performs centralized analysis. This segmentation allows fault detection without requiring continuous high-bandwidth communication for complete log transfers.
Solution Approach 2:
Terminals perform preliminary self-diagnosis and self-recovery actions using locally stored recovery methods before management device intervention is needed. This preliminary action enables early fault detection and recovery without requiring constant communication with the management device.
2Measurement precision
If the management device performs centralized fault analysis, then comprehensive fault detection is improved, but response time increases
Solution Approach 1:
Fault analysis is divided into terminal-level self-diagnosis and management device-level centralized analysis. The terminal-level segmentation enables immediate local response to detected faults, while centralized analysis provides comprehensive monitoring across all terminals.
Solution Approach 2:
Terminals perform self-diagnosis and self-recovery operations autonomously when faults are detected. This self-service capability eliminates the delay inherent in centralized manual intervention, allowing immediate response to faults while maintaining comprehensive system monitoring.
3Productivity
If terminals perform self-recovery processing, then recovery speed is improved, but redundancy of recovery actions may occur
Solution Approach 1:
Terminals send feedback notifications to the management device upon completing self-recovery operations. The management device uses this feedback to identify which terminals have already recovered and can suppress redundant recovery orders for those terminals, preventing unnecessary duplicate actions.
Solution Approach 2:
The management device receives recovery status feedback from terminals and adjusts its recovery ordering accordingly. This feedback mechanism enables the system to coordinate recovery actions across multiple terminals, preventing redundancy while maintaining high recovery speed.
Data Source
AI summary
A communication system includes a management device connected to terminals. The terminal is configured to collect log information, send the log information to the management device, analyze the log information to determine whether an abnormal event occurs in the terminal and determining self-recovery processing, notify the management device of the self-recovery processing for the abnormal event, and execute the self-recovery processing for the abnormal event or recovery processing ordered by the management device. The management device is configured to analyze log information collected from the terminals to determine whether an abnormal event occurs in the terminal, determine recovery processing, receive a notification about self-recovery processing from the terminal, and issue an order to execute the recovery processing for the detected abnormal event to the terminal, depending on whether the notification has been received.
