Monitoring Alarm Logic with Cascading Fault Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current monitoring systems suffer from unclear differentiation between alarm and recovery logic, leading to increased false alarms, storage overheads, CPU consumption, and reduced system availability due to lack of unified fault analysis methods and consideration of device relationships.
Innovation Solution
Implementing independent alarm and recovery logic based on device models, with exclusive execution and delay processing, and establishing cascading relationships between alarm events to reduce false alarms and improve analysis referability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional single fault analysis function is used with simple fault generation and recovery conditions, then system implementation is simple, but quantity of repeated alarms increases significantly
Solution Approach 1:
The patent divides the fault analysis function into separate alarm generation module and alarm recovery module with distinct execution conditions. The alarm generation module executes when fault conditions are met, while the recovery module executes when recovery conditions are met, preventing repeated alarms by segmenting the single fault analysis function into specialized sub-functions.
2Device complexity
If device alarm logic and recovery logic are not clearly differentiated, then system implementation is simple, but probability of false alarms increases
Solution Approach 1:
The patent clearly differentiates alarm logic and recovery logic by separating them into distinct modules with specific execution conditions. The alarm generation module contains logic for detecting fault conditions and generating alarms, while the recovery module contains logic for detecting recovery conditions and clearing alarms, eliminating false alarms through logical differentiation.
Solution Approach 2:
The patent implements feedback mechanisms where the alarm generation module monitors device parameters and provides feedback when fault conditions are detected, triggering alarm generation. Similarly, the recovery module monitors and provides feedback when recovery conditions are met, triggering alarm clearance. This feedback-based approach ensures accurate alarm management.
3Adaptability or versatility
If system executes fault analysis procedures chaotically without unified methods, then system implementation is flexible, but system function availability is reduced
Solution Approach 1:
The patent creates a universal fault analysis framework that can handle multiple alarm types and recovery scenarios through a unified method. The alarm generation module and recovery module are designed to work together in a standardized sequence, providing consistent and reliable fault analysis across different device types and fault conditions, thereby improving system function availability.

AI summary
The present invention relates to a fault diagnosis and intelligent warning method for monitoring a system device, including the following steps: step 1. establishing independent alarm analysis logic and independent recovery analysis logic based on a fault model of each alarm; step 2. controlling the alarm logic and the recovery logic to be mutually exclusively executed; the step 3. performing delay processing on an alarm event and a recovery event; and step 4. establishing a cascading relationship between alarm events generated after the delay processing: establishing an alarm cascading group based on a relationship between different alarm events, automatically determining, by using generation of an alarm event as a triggering condition, whether alarms in a same cascading group simultaneously exist within a time, and generating association information between alarm events. Compared with the prior art, the present invention has the following advantages: reducing a probability of occurrence of false alarms, reducing a quantity of invalid alarms, reducing storage space overheads, reducing system CPU consumption, reducing workloads of maintenance personnel, and the like.
