Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In facilities like plants, there is a challenge in accurately sharing information about changes in setting parameter values of field devices between on-site workers and managers due to distance and manual communication methods, leading to potential errors or missed notifications.
Innovation Solution
A change detection apparatus and system that automatically acquires and outputs change information for setting parameters, including related and non-target parameters, to a maintenance and management apparatus, which registers and manages unique device information and setting parameters, ensuring accurate sharing and detection of changes across the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If field devices are installed at remote sites to improve facility operations, then operational capability is enhanced, but information sharing between on-site workers and managers deteriorates due to distance and manual communication methods
Solution Approach 1:
The system implements automatic feedback mechanisms where field devices transmit setting parameter changes directly to management systems through network communication. This eliminates manual information transfer and ensures accurate, real-time sharing of change information between on-site workers and managers, resolving the information loss caused by distance.
Solution Approach 2:
The patent replaces manual communication methods (mechanical information transfer) with automated electronic monitoring and network-based communication. The change detection apparatus automatically captures and transmits parameter changes, substituting human-mediated information sharing with an automated electronic system that maintains accuracy regardless of distance.
2Device complexity
If manual communication methods are used to report parameter changes, then system complexity is reduced, but information accuracy and timeliness deteriorate due to human error and delayed notification
Solution Approach 1:
The field devices perform self-monitoring of their own setting parameters and automatically generate change notifications without human intervention. This self-service capability ensures that parameter changes are detected and reported accurately and timely, eliminating human error while the automated nature of the system manages complexity through standardized protocols.
3Loss of information
If all setting parameters are monitored to ensure complete change detection, then information completeness is improved, but system complexity and data processing burden increase
Solution Approach 1:
The system extracts and monitors only the critical setting parameters that are most likely to change or have significant impact on operations. By selectively monitoring specific parameters rather than all parameters, the system maintains information completeness for important changes while reducing data processing burden and system complexity.
Solution Approach 2:
The monitoring system focuses on detecting changes in setting parameters rather than continuously analyzing all parameter values. This change-detection approach allows the system to maintain completeness of change information while reducing processing complexity by only flagging and reporting actual changes rather than continuously analyzing steady-state values.

AI summary
[Objective] Recently, there is a desire to accurately share information concerning the presence or absence and content of a change in a setting parameter value. [Means for Achieving the Objective] Provided is a change detection apparatus including a parameter acquiring section that acquires a value of at least one setting parameter of a field device, at predetermined time intervals; a change detecting section that detects whether the value of the setting parameter has been changed; and a change information output section that outputs change information, in response to a change in the value of the setting parameter having been detected.
