Solution Overview
Problem
Complex production facilities with diverse equipment and systems generate mixed alarms, making it difficult to prioritize and unify alarm information, leading to challenges in intelligent decision-making and flexible response to changing circumstances.
Innovation Solution
An alarm information processing device and method that collects and normalizes alarm information from various formats, allowing user-set logic for normalization, enabling unified information processing and flexible adaptation to individual circumstances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If alarm information from various equipment and systems is collected and displayed separately, then safety of the plant is ensured, but it becomes difficult to prioritize alarms and execute unified information processing
Solution Approach 1:
The patent merges alarm information from multiple sources (field equipment, controllers, safety systems) into a unified alarm management system. The normalization means consolidates alarms with different formats, categories, and priority levels into a standardized representation, enabling centralized display and processing while maintaining the reliability benefits of comprehensive alarm collection.
Solution Approach 2:
The alarm information processing device provides universal handling capabilities for diverse alarm types. The normalization means creates a unified alarm structure that can represent various alarm formats (different equipment models, manufacturers, and systems), allowing the system to process and prioritize alarms from heterogeneous sources through a single interface.
2Measurement precision
If alarm information in different formats is handled separately, then individual alarm accuracy is maintained, but unified information processing and intelligent decision-making become impossible
Solution Approach 1:
The normalization means transforms alarm information by changing its parameter representation. Different alarm formats (with varying data structures, priority encodings, and categorization schemes) are converted into a standardized parameter set, preserving the semantic meaning and accuracy of each alarm while enabling unified processing and intelligent decision-making across diverse alarm types.
3Ease of manufacture
If a fixed alarm handling system is implemented, then initial alarm management requirements are met, but the system cannot adapt to new equipment models or changing plant circumstances
Solution Approach 1:
The alarm information processing device implements dynamic adaptability through its normalization means, which can accommodate new alarm formats and equipment models without requiring complete system redesign. The system dynamically adjusts to handle new alarm types by normalizing their data structures, allowing the plant to introduce new equipment or modify alarm handling requirements while maintaining unified processing capabilities.

AI summary
There are provided an alarm information processing device and an alarm information processing method capable of handling alarm information in unification and of exhibiting flexible adaptability in response to the circumstances. A collection unit collects alarm information having a plurality of mixed formats. A normalization unit normalizes alarm information collected by the collection unit. An information processing unit executes information processing relative to the alarm information normalized by the normalization unit. A user setting unit is used for setting a logic for normalization by a user in the normalization unit.
