Plant Maintenance Data Standardization for Calibration Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional maintenance systems for industrial plants struggle to effectively utilize work information from calibration and adjustment processes, as this information is not readily analyzable or diagnosable due to its format, limiting its usefulness for plant and instrument analysis.
Innovation Solution
An apparatus and method that extracts and processes work information from various maintenance apparatuses, converting it into a standardized format for analysis and diagnosis, including worker information and working time, and displays it in a format suitable for analysis and diagnosis, allowing for better utilization of the collected data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If work information is collected from multiple maintenance apparatuses in various formats, then the quantity of available data increases, but the complexity of processing and analyzing this data increases
Solution Approach 1:
The patent segments work information into standardized data elements with defined structures and formats. Each maintenance apparatus outputs data in a standardized format that can be independently processed, allowing the system to handle multiple data sources without proportional increases in processing complexity.
Solution Approach 2:
The patent transforms work information from various formats into a standardized parameter structure. By changing the format parameters of incoming data to match a predefined standard, the system enables consistent analysis across different maintenance apparatuses while simplifying processing requirements.
2Reliability
If work information is stored in original formats from different maintenance apparatuses, then the authenticity of the data is preserved, but the ease of analysis and diagnosis deteriorates
Solution Approach 1:
The patent introduces a standardized data structure as an intermediary between the original maintenance apparatus formats and the analysis/diagnosis processes. This intermediary format preserves the authenticity of source data while making it readily analyzable through consistent structure and standardized parameters.
3Ease of operation
If work information is converted to a standardized format, then the ease of analysis and diagnosis improves, but the complexity of the data processing system increases
Solution Approach 1:
The patent creates a universal standardized data format that serves multiple functions: data collection, storage, analysis, and diagnosis. This single standardized structure replaces the need for multiple specialized processing systems, reducing overall system complexity while improving analytical capabilities.
4Loss of information
If detailed work information including worker information and working time is collected, then the usefulness for performance analysis improves, but the quantity of data to be processed increases
Solution Approach 1:
The patent extracts only the essential data elements needed for analysis and diagnosis from the complete work information, including worker information and working time. By selecting and standardizing only the relevant parameters, the system maintains high analytical usefulness while reducing the total quantity of data that requires processing.
