Alarm Display System with Support Information Addition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In monitoring systems for devices in a plant, a large number of alarms can bury the alarms that need to be monitored and noticed, as existing systems do not display support information associated with all alarm signals, making it difficult for operators to identify critical alerts amidst numerous notifications.
Innovation Solution
An alarm display system that includes a database storing event information, occurrence probabilities, checking situations, and countermeasure policies, along with an acquisition unit for alarm data and a support information addition unit that adds relevant information to the alarms, allowing for chronological display and highlighting of necessary countermeasures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all alarm information is displayed, then operators can check all generated alarm information, but alarms that need to be monitored are buried among numerous notifications
Solution Approach 1:
The alarm information is segmented into multiple categories including current alarms, historical alarms, alarm events, and alarm logs. This segmentation allows operators to view only relevant alarm types rather than all alarms simultaneously, reducing information overload while maintaining access to complete alarm data when needed.
Solution Approach 2:
Different display regions are assigned different functions: the first display region shows current alarms with high visibility, the second region shows historical alarms, and the third region shows alarm events. Each region has optimized display characteristics suited to its purpose, with current alarms receiving prominent placement and visual emphasis.
2Ease of operation
If support information is added to all alarm information, then operators can easily identify critical alarms, but system complexity increases
Solution Approach 1:
Alarm priorities and support information are predetermined and stored in a database before alarms occur. When an alarm is generated, the system retrieves pre-configured priority levels and associated support information from the database, eliminating the need for complex real-time analysis while ensuring consistent prioritization.
Solution Approach 2:
A database serves as an intermediary between the alarm generation system and the display system. The database stores alarm priority levels, countermeasure information, and display parameters, allowing the display controller to add support information without direct complex processing. This intermediary layer simplifies the overall system architecture while enabling sophisticated alarm prioritization.

AI summary
An alarm display system includes: a database configured to store a plurality of sets of predetermined events, occurrence probabilities of the events, checking situations of the events, and countermeasure policies of the events in association with the sets; an alarm information acquisition unit configured to acquire alarm information indicating that the events occur in monitoring target devices; a support information addition unit configured to add support information for supporting determination of a countermeasure for the alarm information according to information stored in the database, to the acquired alarm information; and a display unit configured to display alarm display information in which the support information is added.
