Process Line HMI Layout for Dynamic Looper Movement Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional SCADA HMI systems lack the capability to easily represent looper operations in steel rolling systems, as they do not provide specialized screen parts for dynamic representation of looper movements.
Innovation Solution
A process line HMI system that renders a movable looper group and fixed roll parts on the HMI screen, calculates the looper movement amount by dividing the difference between the total and current process line lengths, and adjusts the relative positions of the fixed and movable roll parts accordingly, allowing dynamic representation of looper operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional SCADA HMI systems are used, then the system structure is simple, but the capability to represent looper operations dynamically is insufficient
Solution Approach 1:
The HMI screen is divided into specialized screen parts, each responsible for representing specific process line components (fixed roll parts, movable looper group parts). This segmentation enables dynamic representation of looper operations while maintaining a structured and manageable system architecture.
Solution Approach 2:
The screen parts are designed to dynamically change their shape and relative positions based on real-time looper operation data. The movable looper group part can adjust its position relative to fixed roll parts, and the screen parts can change their geometric representation to reflect the actual physical state of the process line, enabling versatile representation without requiring a completely complex system redesign.
2Adaptability or versatility
If specialized screen parts are introduced for looper representation, then the representation capability is improved, but the screen complexity increases
Solution Approach 1:
The specialized screen parts are designed with multi-functionality, serving both as visual representations of process line components and as dynamic indicators of looper operation state. Each screen part can represent different aspects (position, shape, status) depending on the operational context, reducing the need for additional specialized components and thereby controlling screen complexity while maintaining high representation capability.
3Measurement precision
If the HMI screen dynamically changes to represent looper operation, then the monitoring accuracy is improved, but the processing complexity increases
Solution Approach 1:
The HMI screen implements continuous feedback mechanisms where screen parts automatically update their representation based on real-time data from the looper operation. The system monitors process line parameters and dynamically adjusts the screen part configurations to reflect the current state, ensuring high monitoring accuracy while automating the processing to minimize manual intervention and control complexity.

AI summary
An HMI renders on an HMI screen a process line which includes: a movable looper group part obtained by grouping at least one movable roll part and a plurality of line parts connected to the movable roll part; and a plurality of fixed roll parts connected to the movable looper group part. The HMI continuously obtains a process line length from an output signal of a monitoring target device. The HMI calculates a looper movement amount by dividing a difference between a process line total length and the process line length by the number of parts in the plurality of line parts which are shared by the movable looper group part with the plurality of fixed roll parts. The HMI changes a relative position between the plurality of fixed roll parts and the movable looper group part on the HMI screen according to the looper movement amount.
