XY Trend Diagram Control for Operating Point Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control systems for technical installations require in-depth process-engineering knowledge for operators to manually adjust and optimize operating points, making the process inefficient and error-prone due to the complexity of identifying relationships between process measurement values and influencing factors.
Innovation Solution
A control system with an operator station server and client that generates and transmits interactive XY trend diagrams, allowing operators to visualize and influence operating points by referencing object models of underlying technical objects, enabling targeted adjustments without extensive knowledge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual adjustment of operating points is performed by operators, then operating point optimization can be achieved, but the process requires in-depth process-engineering knowledge and is error-prone
Solution Approach 1:
The patent introduces an intermediary system (the control system with XY trend diagram and object model presentation) that mediates between the operator and the complex process-engineering relationships. This intermediary automatically identifies and presents relevant technical objects and their relationships, eliminating the need for operators to have deep process-engineering knowledge while ensuring accurate, error-free adjustments.
Solution Approach 2:
The control system performs self-service by automatically analyzing the operating point, identifying relevant technical objects, and presenting them to the operator. The system autonomously determines which objects influence the operating point and what relationships exist between them, reducing reliance on operator expertise while maintaining optimization quality.
2Productivity
If operators manually adjust process variables to set operating points, then operating point optimization can be achieved, but the process is time-consuming and inefficient
Solution Approach 1:
The control system performs preliminary action by pre-identifying and presenting all relevant technical objects and their relationships before the operator needs to make adjustments. The system proactively analyzes the operating point, determines which technical objects influence it, and organizes this information in advance, eliminating the time-consuming manual exploration process.
Solution Approach 2:
The system implements feedback by continuously monitoring the operating point and automatically updating the presentation of relevant technical objects based on current conditions. This real-time feedback mechanism allows the system to adapt to changing conditions and guide operators efficiently, reducing the time required for optimization while improving productivity.
3Ease of operation
If comprehensive information about technical objects is provided to operators, then operating point optimization becomes easier, but the system complexity increases
Solution Approach 1:
The patent applies local quality by providing comprehensive information about technical objects only when and where it is relevant to the current operating point optimization task. Instead of presenting all possible system information uniformly, the system selectively displays detailed information about specific technical objects that directly influence the current operating point, making the system easier to operate without unnecessarily increasing perceived complexity.
Solution Approach 2:
The control system segments the complex information about technical objects into organized, manageable groups based on their relationship to the operating point. By dividing the information architecture into hierarchical levels (operating point → relevant technical objects → specific parameters), the system makes comprehensive information accessible without overwhelming the operator, effectively managing system complexity through structured segmentation.
Data Source
AI summary
A control system of a technical installation includes an operator station client and an operator station server that has a visualization service and stored object models of technical objects of the technical installation and generates an XY trend diagram with an operating point visualized in the XY trend diagram from a first measurement value associated with the first technical object and a second measurement value associated with the second technical object, and transmits the XY trend diagram with the operating point to the operator station client via the visualization service, wherein the XY trend diagram and/or the operating point has a reference to an object model, the operating point is influenceable by the technical object underlying the referenced object model, and an operator of the operator station client is visually presented with the referenced object model via the visualization service when selecting the operating point in the XY trend diagram.
