Field Device Status Display Integration via Unified Representation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for monitoring field devices in a plant are inefficient and inconvenient due to different algorithms and data inputs, leading to inaccurate status displays and incorrect prioritization of critical device statuses, which can result in incorrect status representations for parent folders.
Innovation Solution
A system comprising a data acquisition module, two diagnosis engines (Basic Diagnosis Engine and Advanced Diagnosis Server), and a client with user input capabilities, which calculates and integrates multiple status values from field devices using predefined images for accurate representation, allowing user override and selection of statuses for improved monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different applications use different internal algorithms to calculate status values, then each application can optimize for its specific function, but the status values from different applications cannot be integrated and displayed together
Solution Approach 1:
The patent introduces a common status value representation standard as an intermediary between different diagnosis applications. Each application calculates its status using its own algorithm, but all results are converted to a unified status value format that can be integrated and displayed together in the same interface, enabling both application-specific optimization and system-wide integration
2Productivity
If the status colour is determined by the most critical value in a parent folder, then the display highlights the most urgent issue, but the status may be incorrect if the critical value comes from an unimportant field device
Solution Approach 1:
The patent applies different weighting or importance factors to different field devices within the same parent folder. When determining the parent folder's status colour, the system considers both the criticality of the status value and the importance of the source device, so that a critical value from an unimportant device does not override a less critical value from an important device
3Reliability
If status values are displayed separately in different applications, then each application maintains its own calculation integrity, but monitoring the overall plant status becomes inefficient and inconvenient
Solution Approach 1:
The patent creates a universal status display interface that can aggregate and display status values from multiple different diagnosis applications simultaneously. The common status value representation enables the same display mechanism to handle diverse status types from different applications, providing both application-specific integrity and overall plant monitoring capability
