Equipment Alarm Display for Maintenance and Abnormality Differentiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current information processing devices for production facilities lack effective means to distinguishably present the state of equipment, making it difficult for personnel to determine when maintenance is needed or if an abnormality has occurred, as they do not adequately differentiate between maintenance and abnormality alarms.
Innovation Solution
An information processing device with a communication interface and controller that receives equipment state information, outputs a first alarm for maintenance and a second alarm for abnormalities, and distinguishes between the two in a recognizable manner, allowing for appropriate determination of equipment state and necessary actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If alarm information is displayed in a unified manner, then the device complexity is reduced, but the ability to appropriately determine equipment state deteriorates
Solution Approach 1:
The alarm display is segmented into distinct visual representations for different alarm types. Maintenance alarms and abnormality alarms are separated with unique icons, colors, or display patterns, allowing operators to quickly distinguish between different equipment states without complex analysis of unified alarm messages.
2Loss of information
If detailed alarm information is provided, then the ability to determine equipment state improves, but the ease of operation deteriorates
Solution Approach 1:
Different visual qualities are applied to different alarm types to convey specific information efficiently. For example, maintenance alarms may use yellow coloring with specific icons, while abnormality alarms use red coloring with different icons. This allows operators to grasp equipment state at a glance without reading detailed information, improving both information delivery and operational ease.
3Loss of information
If alarm types are differentiated, then the ability to determine equipment state improves, but the device complexity increases
Solution Approach 1:
The system uses color coding to differentiate alarm types visually. Maintenance alarms are displayed in one color (e.g., yellow) while abnormality alarms are displayed in another color (e.g., red). This simple visual differentiation conveys rich information about alarm types without requiring complex processing or display mechanisms.

AI summary
For equipment in a production facility, information for more appropriately determining a state of the equipment is presented. The information processing device: receives information indicative of a state of equipment in a production facility (S202); carries out a process of outputting, when the received information indicative of the state of the equipment satisfies a first condition, a first alarm for prompting maintenance of the equipment (S204); carries out a process of outputting, when the information indicative of the state of the equipment satisfies a second condition, a second alarm that indicates occurrence of abnormality or a sign of abnormality in the equipment (S206); and carries out a process of outputting, in a distinguishably recognizable manner, a tendency in which the first alarm is outputted and a tendency in which the second alarm is outputted (S207).
