Alarm Filtering by Monitoring Terminal Role and Target
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing alarm management systems experience high communication volume between the server and monitoring terminals due to the unnecessary transmission of all alarm messages, leading to potential overlooking of important alarms.
Innovation Solution
An alarm management system that filters alarms based on filtering conditions, such as viewing authority and desired targets, and transmits only updated information, reducing the communication volume by presenting filtered alarms to operators via monitoring terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the server transmits all alarm message information to every monitoring terminal, then complete alarm information is provided to operators, but the communication volume between server and monitoring terminals becomes excessively large
Solution Approach 1:
The alarm management apparatus performs preliminary filtering of alarm messages before transmission to monitoring terminals. By pre-processing alarm information and removing redundant messages that operators do not need to see, the system reduces communication volume while ensuring that only relevant alarm information is transmitted to each terminal.
Solution Approach 2:
The system applies different filtering criteria to different monitoring terminals based on their specific contexts, such as the operator's role, the terminal's location, and the relevance of alarm types. This localized filtering approach ensures that each terminal receives appropriately tailored alarm information, minimizing unnecessary communication while maintaining information completeness for each user.
2Loss of information
If all alarm messages are transmitted to monitoring terminals, then operators receive comprehensive alarm data, but important alarms may be overlooked due to information overload
Solution Approach 1:
The alarm management apparatus extracts and prioritizes critical alarm information from the complete set of alarm messages. By identifying and separating important alarms from routine or less critical messages, the system ensures that operators can quickly identify and respond to significant events without being overwhelmed by the full volume of alarm data.
Solution Approach 2:
The system performs preliminary prioritization and filtering of alarm messages before they reach the monitoring terminal. By pre-organizing alarm information based on urgency, type, and relevance, the system prepares the alarm data in a way that enhances operator ability to recognize important alarms while maintaining access to complete alarm information when needed.

AI summary
An alarm management system of the present disclosure includes an alarm management apparatus, a monitoring terminal, and a controller. The alarm management apparatus generates an alarm based on information received from the controller or receives an alarm from the controller, receives information related to a filtering condition from the monitoring terminal, performs filtering on the alarm based on the filtering condition, and presents the alarm subjected to the filtering to an operator via the monitoring terminal.
