Alarm Management System with Remedial Parameter Maps
Solution Overview
Problem
State-of-the-art alarm management systems require significant manual training and operator knowledge to navigate and remediate alarms, leading to time-consuming processes and potential missed critical alarms due to information overflow.
Innovation Solution
An alarm management system with a self-learning correlation module that dynamically updates remedial parameter maps based on operator actions, allowing direct access and editing of control parameters within the alarm display interface, reducing the need for extensive training and improving time efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional alarm management systems are used, then comprehensive control parameter monitoring is achieved, but operator training time and knowledge requirements increase significantly
Solution Approach 1:
The system pre-configures remedial parameter maps that automatically associate alarm conditions with the specific control parameters that need to be investigated. This preliminary organization of information eliminates the need for operators to memorize complex parameter relationships, providing immediate guidance when alarms occur without requiring extensive prior training.
Solution Approach 2:
The patent introduces an intermediary layer (the remedial parameter map and alarm management system) between the alarm condition and the operator. This intermediary automatically processes and presents relevant control parameter information, reducing the cognitive burden on operators and eliminating the need for them to have deep domain knowledge about parameter relationships.
2Reliability
If traditional alarm management systems are used, then complete control parameter investigation is possible, but alarm remediation time increases
Solution Approach 1:
The system pre-establishes remedial parameter maps that identify and organize the specific control parameters relevant to each alarm condition before the alarm occurs. When an alarm is triggered, the system immediately presents the pre-identified parameters, allowing operators to quickly investigate and remediate without needing to systematically navigate through all possible parameters, thus maintaining completeness while reducing time.
3Reliability
If comprehensive alarm information is displayed, then complete alarm monitoring is achieved, but information overflow and alarm flooding occur
Solution Approach 1:
The patent segments alarm information by organizing it into remedial parameter maps that group control parameters according to their relationship with specific alarm conditions. This segmentation allows the system to present only the relevant subset of parameters for each alarm, preventing information overload while maintaining complete monitoring capability across all alarms.
Solution Approach 2:
The system applies local quality by providing different information presentations based on the specific alarm condition. Instead of uniformly displaying all control parameters for every alarm, the remedial parameter maps provide tailored, condition-specific information, reducing operator workload while ensuring each alarm receives appropriate attention.
4Adaptability or versatility
If multiple user interfaces are used for control parameter access, then comprehensive control functionality is achieved, but navigation time increases
Solution Approach 1:
The patent merges the alarm display functionality with direct access to control parameters by integrating the remedial parameter maps into the alarm interface. This consolidation allows operators to access and modify control parameters directly from the alarm display without navigating through multiple separate user interfaces, maintaining full control functionality while dramatically reducing access time.

AI summary
The present invention discloses an alarm management system and a method for operating the same. The alarm management system is suitable for use in a control system. Accordingly to the techniques of the present invention, a remedial parameter map corresponding to at least one alarm code is maintained, the remedial parameter map being a set of control parameters. During operation, at least one alarm message is received from the control system, and rendered, along with a corresponding remedial parameter map, in an alarm display interface.
