Alarm Queue Normalization and Filtering for Multi-System Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing alarm processing systems face challenges in providing consistent alarm formats and removing duplicate alarms, making it difficult for administrators and users to manage and interpret alerts from multiple monitoring systems, particularly in HVAC systems.
Innovation Solution
The system employs a computing device with a processor and memory to generate, normalize, and filter alarms, using an alarm transformation manager to convert different alarm types into a uniform format, and an alarm suppression engine to identify and remove duplicate alarms, ensuring that only relevant alerts are pushed to applications or users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple monitoring systems and sensors are used to monitor system values, then monitoring coverage and detection capability are improved, but alarm format consistency and duplicate alarm management deteriorate
Solution Approach 1:
The patent introduces an alarm management system as an intermediary component between multiple monitoring systems and the user interface. This alarm management system receives alarms from various sources, normalizes their formats, and presents them in a unified manner, thereby resolving the contradiction between comprehensive monitoring coverage and alarm format consistency.
Solution Approach 2:
The alarm management system performs multiple functions including receiving alarms from different sources, normalizing formats, filtering duplicates, and presenting unified alarms. This multi-functional approach allows a single system to handle diverse alarm sources while maintaining consistency, addressing the contradiction between monitoring coverage and format management.
2Reliability
If additional sensors and alarm generators are deployed to enhance monitoring capability, then system detection ability is improved, but duplicate alarm generation and user confusion increase
Solution Approach 1:
The alarm management system extracts and identifies duplicate alarms by comparing alarm data from multiple sources. When duplicate alarms are detected, the system filters them out or consolidates them into a single alarm notification, thereby removing the harmful duplicate information while preserving the essential monitoring capability.
Solution Approach 2:
The system converts the potentially harmful effect of duplicate alarms into a benefit by using the redundancy to improve reliability. The alarm management system leverages multiple alarm sources to ensure comprehensive detection while simultaneously filtering duplicates to maintain clarity, thus transforming the contradiction into an advantage.
3Productivity
If pre-configured alarm formats are used in multiple systems, then alarm generation capability is improved, but format consistency across systems deteriorates
Solution Approach 1:
The alarm management system dynamically adjusts and normalizes alarm format parameters from different sources into a unified structure. By changing the format parameters of incoming alarms to match a standard template, the system maintains consistency across diverse alarm sources while preserving the ability to generate alarms from multiple systems.
Data Source
AI summary
Devices, methods, and systems for alarm processing are described herein. One computing device for alarm processing, includes a memory and a processor configured to execute executable instructions stored in the memory to generate a first alarm for a first system based on a monitored value for the first system, receive a second alarm generated by a second system based on a monitored value for the second system, send the first alarm and the second alarm to an alarm queue, filter the alarm queue based on the monitored values associated with the first alarm and the second alarm within the alarm queue, and push the first alarm or the second alarm within the alarm queue to an application based on the filtering.
