Machine Alarm Reporting Logic for Timely Abnormality Escalation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing alarm reporting systems may delay the notification of critical machine abnormalities due to daily transmission of history information, potentially hindering timely response to important issues.
Innovation Solution
An alarm reporting apparatus that determines the necessity of reporting based on pre-set criteria, including the type of abnormality, machine operation status, and elapsed time since the abnormality occurred, allowing for immediate notification of critical issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If alarm history information is transmitted once a day, then communication load is reduced, but response time to critical abnormalities is delayed
Solution Approach 1:
The patent applies local quality by differentiating reporting requirements based on abnormality severity. Critical abnormalities (e.g., safety issues, major failures) trigger immediate reporting regardless of communication load, while minor abnormalities follow the daily batch reporting schedule. This selective approach ensures timely response to important issues while maintaining reduced communication for less critical cases.
Solution Approach 2:
The system dynamically adjusts reporting frequency based on the nature and severity of each abnormality. Instead of a fixed daily reporting schedule, the system transitions from static batch reporting to dynamic event-driven reporting, where the reporting interval is determined by the criticality level of the detected abnormality, allowing immediate reporting for severe cases while maintaining energy efficiency for minor issues.
2Loss of time
If all alarm information is reported immediately, then response time is improved, but communication load increases
Solution Approach 1:
The patent implements local quality by applying different reporting strategies to different types of abnormalities. Critical abnormalities such as safety hazards and major failures trigger immediate reporting with high priority, while minor abnormalities are deferred to the next scheduled communication window. This differentiated approach ensures rapid response to important issues without unnecessarily increasing communication load for all alarm types.
3Loss of energy
If alarm reporting is delayed until daily batch transmission, then communication efficiency is improved, but operational disruption risk increases
Solution Approach 1:
The system applies local quality by differentiating between critical and non-critical abnormalities in terms of reporting urgency. For critical abnormalities that could cause operational disruption or safety issues, the system immediately reports regardless of communication efficiency considerations. For non-critical abnormalities, the system maintains efficient batch reporting. This selective approach preserves operational reliability for critical cases while maintaining communication efficiency for minor issues.

AI summary
An alarm reporting apparatus determines that an alarm reporting is necessary if an abnormality occurring in a machine is to be constantly reported, determines that the alarm reporting is not necessary if the abnormality is to be reported during operation and the machine is not during operation, determines that the alarm reporting is not necessary if the abnormality is to be reported during operation, the machine is during operation, and an elapsed time from the occurrence of the abnormality has not exceeded a set monitoring time, and determines that the alarm reporting is necessary if the abnormality is to be reported during operation, the machine is during operation, and the elapsed time from the occurrence of the abnormality has exceeded the set monitoring time. When it is determined that the alarm reporting is necessary, the alarm reporting apparatus reports, to a monitoring apparatus, an alarm related to the corresponding machine.
