Plant Instrument Maintenance Data Formatting for Calibration Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for maintaining industrial plants lack efficient systems to analyze and diagnose instrument calibration and adjustment data, as the work information collected is not in a suitable format for analysis or diagnosis.
Innovation Solution
A device and method that acquire, extract, and generate output information from work information related to instrument calibration and adjustment, converting it into a predetermined format for storage and display, allowing for analysis and diagnosis of plant and instrument performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If work information is collected manually by workers and summarized in reports, then the information can be recorded, but it cannot be easily used for analysis or diagnosis of plant or instrument performance
Solution Approach 1:
The patent segments work information into structured data elements with specific formats for different maintenance apparatuses. By dividing the information into standardized components (measurement values, timestamps, operator IDs, etc.), the system enables efficient analysis while keeping the collection process simple through automated format recognition.
Solution Approach 2:
The patent introduces an information processing apparatus as an intermediary between maintenance apparatuses and analysis systems. This mediator automatically converts raw work information into standardized formats, enabling analysis without requiring complex manual processing or direct integration between diverse maintenance tools and analysis platforms.
2Adaptability or versatility
If multiple types of maintenance apparatuses are used for calibration and adjustment, then comprehensive maintenance can be performed, but the work information from different apparatuses has different formats making it difficult to process uniformly
Solution Approach 1:
The patent creates a universal output format that can accommodate data from multiple types of maintenance apparatuses. The information processing apparatus automatically identifies the source apparatus type and converts its specific format into the standardized universal format, enabling one system to handle diverse inputs without requiring separate processing paths for each apparatus type.
Solution Approach 2:
The patent changes the format parameters of work information based on the source apparatus type. By automatically adjusting data structure, field names, and organization according to the originating device, the system maintains compatibility across different maintenance apparatuses while producing uniform output suitable for centralized processing and analysis.
3Reliability
If work information is stored in various formats from different maintenance apparatuses, then data from all apparatuses can be retained, but it cannot be efficiently stored or displayed in a unified manner
Solution Approach 1:
The patent performs preliminary format conversion immediately when work information is generated by maintenance apparatuses. By converting data to the standardized output format at the point of creation rather than during subsequent storage or analysis operations, the system ensures complete information retention while enabling efficient unified storage and display from the outset.
Data Source
AI summary
To effectively utilize work information acquired by maintenance of an instrument in a plant, an apparatus is provided, which includes an acquisition unit that acquires work information about at least one of a calibration or an adjustment performed on the instrument in a plant; an extraction unit that extracts a plurality of data elements to be included in output information having a predetermined output format from the work information; and a generation unit that generates the output information from the plurality of data elements.
