Plant Analysis Graph Interface for Faster Abnormality Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In large-scale plants, events like plant wall surface deterioration or filter clogging, which cannot be directly measured by sensors, require manual analysis with high labor and expertise, making it difficult to accurately detect abnormal states and determine contributing factors.
Innovation Solution
A plant operation assistance device with a data selection interface that allows operators to choose data ranges on graphs, record operations, and generate analysis graphs, reducing the workload by displaying related data and providing guidance on analysis procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual analysis by operator is performed for events without established detection methods, then detection accuracy may be improved, but analysis workload and time consumption increase significantly
Solution Approach 1:
The patent introduces an automated analysis system that acts as an intermediary between raw measurement data and operator judgment. The system automatically selects relevant measurement data based on event types, performs preliminary analysis, and presents structured results to operators, thereby reducing manual analysis time while maintaining detection accuracy
Solution Approach 2:
The system performs preliminary data selection and organization automatically before operator review. By pre-processing measurement data, identifying relevant parameters, and structuring analysis results in advance, the system reduces the time operators need to spend on initial data gathering and preparation
2Measurement precision
If comprehensive measurement data is collected for factor analysis, then analysis accuracy is improved, but data processing complexity and operator burden increase
Solution Approach 1:
The system extracts and selects only the measurement data relevant to specific event types from the comprehensive dataset. By automatically identifying and extracting relevant parameters based on event characteristics, the system reduces data processing complexity while maintaining analysis accuracy
Solution Approach 2:
The patent segments the comprehensive measurement data into event-type-specific subsets. By dividing the large dataset into manageable, relevant portions based on event categories, the system reduces processing complexity while preserving all necessary information for accurate analysis
Data Source
AI summary
A plant operation assistance device is provided which provides a display interface capable of reducing an operator's load in analysis work. The plant operation assistance device includes a data selection means, a data selection database, a measurement data database, a display data collection unit, and a data analysis graph creation unit. The data selection database records information on the operation performed by an operator through the data selection means. The data analysis graph creation unit creates a data analysis graph for displaying data of a second graph related to operator selected data of a first graph.
