Production Line Signal Display for Faster Abnormality Localization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monitoring systems for machine facilities in production lines require manual checking of each component to detect abnormalities, making it time-consuming to identify when and where an abnormality occurs.
Innovation Solution
An information processing apparatus that displays the operation state of a machine facility on a display unit, including the operation time of a specific device and related signals, allowing for real-time monitoring and quick identification of abnormalities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
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 segments the machine facility operation into multiple processes and divides control signals into groups associated with each process. The display unit shows process information in a time-series graph with control signals organized by process, allowing operators to quickly identify which process experienced the abnormality rather than searching through all signals in a list.
Solution Approach 2:
The patent transitions from a one-dimensional list display to a two-dimensional time-series graph display. The graph plots time on the horizontal axis and process status on the vertical axis, with control signals overlaid in their temporal context. This dimensional change enables rapid visual identification of when and where abnormalities occurred.
2Measurement precision
If manual checking of each component is performed to detect abnormalities, then thorough monitoring is achieved, but it is time-consuming to identify when and where an abnormality occurs
Solution Approach 1:
The system automatically collects control signals from the machine facility, processes them through the control unit, and provides immediate visual feedback through the display unit. The time-series graph updates in real-time, showing the status of multiple processes and control signals simultaneously, eliminating the need for manual component-by-component checking while maintaining comprehensive monitoring.
Solution Approach 2:
The patent creates a visual copy of the machine facility's operational state through the time-series graph display. Instead of manually checking physical components, operators can observe a graphical representation that replicates the system's behavior, allowing rapid identification of abnormalities without physical inspection.
3Ease of operation
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 control unit automatically determines process information and organizes control signals by process without requiring manual configuration of measurement references. The system self-configures the time-series graph display based on the control signals it receives, eliminating the need for operators to teach operation start timing for each signal manually.
