Plant Alarm Display Indicator Overlay Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In plant monitoring systems, it is difficult to understand the attributes of alarms due to their small display size and location outside the display area, making it hard to discern alarm attributes without leaving the display area.
Innovation Solution
A display control method that selects and displays an indicator image corresponding to the display attribute within the display area, allowing for the collective display of alarms and indicator images, enhancing visibility and understanding of alarm attributes without needing to move outside the display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If alarm attributes are displayed in a title bar outside the display area, then the display layout is simplified, but the alarm attributes become difficult to understand due to small display size and location
Solution Approach 1:
The patent moves the alarm attribute display from a one-dimensional title bar outside the display area to a two-dimensional overlay within the display area. Indicator images are superimposed on the alarm display region, transforming the spatial arrangement from external to internal positioning, thereby maintaining layout simplicity while dramatically improving attribute visibility and understanding.
2Loss of information
If indicator images are displayed within the display area, then alarm attribute understanding is improved, but the display area becomes more crowded
Solution Approach 1:
The patent implements a nested display structure where indicator images representing alarm attributes are overlaid directly on top of the alarm message display area. This nesting approach allows multiple layers of information (alarm messages and attribute indicators) to occupy the same spatial region, providing comprehensive alarm information without expanding the overall display footprint or crowding the interface.

AI summary
A display control method including selecting an indicator image corresponding to a display attribute which is set for a display area, and performing display control for displaying each alarm corresponding to the display attribute among alarms generated in a plant and also displaying the selected indicator image collectively in the display area.
