Alarm-Linked First Aid Presentation for Time-Series Plant Events
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The plant security management system lacks a configuration for presenting appropriate first aid measures when an event requiring first aid occurs.
Innovation Solution
A first aid presentation system that includes a storage unit for alarm master information and a presentation unit to acquire and present first aid information associated with designated alarms and related alarm master information, utilizing a database to display time series relationships between alarms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a plant security management system uses alarm master information and causal relationship databases to provide information on presumed causes and event spillover, then information completeness is improved, but the system lacks the capability to present appropriate first aid measures
Solution Approach 1:
The alarm master information database is enhanced to serve multiple functions: it not only stores causal relationships and event spillover information but also integrates first aid measures, alarm correlations, and temporal relationships. This multi-functional database structure allows the system to provide comprehensive response guidance without requiring separate specialized systems.
Solution Approach 2:
The information presentation is segmented into distinct components: alarm master information, first aid measures, correlated alarm information, and temporal relationships. This segmentation allows the system to organize complex information hierarchically, presenting relevant first aid measures while maintaining access to broader contextual information when needed.
2Measurement precision
If the system presents comprehensive alarm information including time series relationships, then response accuracy is improved, but information processing complexity increases
Solution Approach 1:
The system pre-processes and stores temporal relationships and correlations between alarms in the alarm master information database during system setup and operation. By preparing this information in advance, the system can quickly retrieve and present accurate first aid measures with contextual information without performing complex real-time analysis, thus maintaining response accuracy while reducing processing complexity during critical events.
3Adaptability or versatility
If the system aggregates knowledge for both actual and rare alarms, then first aid presentation capability is improved, but data storage requirements increase
Solution Approach 1:
The system merges the storage of alarm master information, first aid measures, temporal relationships, and correlated alarm data into a single integrated database structure. This consolidation allows comprehensive knowledge aggregation for both common and rare alarms while optimizing storage efficiency through shared data structures and relationships, avoiding duplication of information across separate systems.

AI summary
A first aid presentation system includes a storage unit that stores one piece or a plurality of pieces of alarm master information associated with each alarm issued from one or a plurality of monitoring targets, information representing each first aid associated with each piece of the alarm master information, and information representing a time series relationship between the respective pieces of alarm master information, and a presentation unit that acquires, from the storage unit, and presents the first aid associated with the alarm master information corresponding to a designated alarm and information relating to another piece of the alarm master information having the relationship with the alarm master information.
