Production Line Signal Timeline Display for Fast Abnormality Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monitoring systems for machine facilities in production lines require manual checking of each component for abnormality, making it time-consuming to identify when and where abnormalities occur, as they rely on displaying control signals in list form and need a reference timing for operation start.
Innovation Solution
An information processing apparatus that displays operation times and signals for each device, using analysis units to determine used signals, create determination conditions, and automatically detect abnormalities, displaying results in a chart for easy identification on a display unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If control signals are displayed in list form on a screen, then the operation state of machine facility can be monitored, but it takes an extremely long time to specify when and where the abnormality occurred
Solution Approach 1:
The patent transforms the one-dimensional list display into a two-dimensional graphical timeline display where the horizontal axis represents time and the vertical axis represents device components. This dimensional transformation allows operators to visually perceive abnormality patterns across multiple devices simultaneously, reducing the time required to locate abnormal points while maintaining complete monitoring capability.
2Measurement precision
If manual checking of each component is performed to locate abnormality, then accurate abnormality detection is achieved, but the process is time-consuming
Solution Approach 1:
The patent employs color-coded visual indicators to represent different operational states and abnormality levels. Normal operations are displayed in one color while abnormal conditions are highlighted in contrasting colors, enabling operators to quickly identify problematic components without manual checking while maintaining detection accuracy through visual pattern recognition.
Solution Approach 2:
The patent divides the complex machine facility into discrete graphical segments representing individual devices and components, each displayed as a separate element on the timeline. This segmentation allows operators to quickly scan and identify abnormal segments without examining the entire system component-by-component, significantly improving abnormality identification speed while maintaining precise detection capability.
3Reliability
If operation start timing is taught as measurement reference for each signal, then monitoring can be performed, but the system complexity increases
Solution Approach 1:
The patent automatically performs preliminary actions by pre-configuring the graphical timeline display structure and pre-establishing the relationships between devices and time markers. When monitoring begins, the system automatically plots device operations on the appropriate time segments without requiring operators to manually configure each measurement reference, thereby maintaining monitoring accuracy while reducing system configuration complexity.
