Slave Device Communication Abnormality Detection and Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In industrial network systems, communication quality can degrade or be interrupted due to cable deterioration or noise, requiring significant changes to the system for monitoring and restoration, and existing methods are time-consuming for users to identify and address abnormalities.
Innovation Solution
An information processing device with a statistical information acquisition unit, abnormality determination unit, and abnormality notification unit that automatically acquires and analyzes communication data to detect abnormalities and notify the master device, allowing for centralized management without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If redundancy measures such as device duplication or ring-shaped network topology are implemented to improve communication reliability, then communication stability is improved, but system complexity and implementation difficulty increase significantly
Solution Approach 1:
The slave device autonomously monitors its own communication quality by acquiring statistical information about communication status and determining abnormalities without requiring external intervention or system reconfiguration. This self-monitoring capability provides reliable communication status detection without adding system complexity.
Solution Approach 2:
The abnormality notification unit provides feedback to the master device when communication abnormalities are detected, enabling the master device to take appropriate actions. This feedback mechanism ensures communication reliability through continuous monitoring and notification without requiring redundant hardware or complex topology changes.
2Reliability
If periodic monitoring of communication quality is implemented through user-operated programs in the master device, then communication abnormality detection is improved, but user burden and operational complexity increase
Solution Approach 1:
The slave device automatically acquires statistical information about its communication status and determines whether abnormalities exist without requiring user intervention. The abnormality notification unit then notifies the master device automatically, eliminating the need for users to operate monitoring programs and significantly reducing operational burden while maintaining reliable abnormality detection.
Solution Approach 2:
The slave device continuously acquires statistical information and determines communication quality in advance, so that when an abnormality occurs, it is immediately detected and notified. This preliminary monitoring action eliminates the need for users to manually check communication status and ensures timely abnormality detection.
