Pseudo-Manipulation Page for DCS Display Latency

Solution Overview

Problem

Current manipulation-monitoring devices in distributed control systems take too long to display pages due to the time required to collect and process large amounts of data, leading to increased load on control devices and delayed page manipulation.

Innovation Solution

Implementing a pseudo-manipulation-monitoring-page displayed using stored page image data without real-time data from control devices until collection is complete, with a display control unit managing the switch to the actual page once data is collected.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If real-time data collection from control devices is performed before page display, then data accuracy is improved, but page display time increases

Engineering Contradiction:

Improvedata accuracyVSAvoidpage display time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary data collection from control devices before the user actually requests page display. By collecting data in advance and preparing it for display, the system ensures data accuracy is maintained while significantly reducing the time required when the user actually requests the page, as the data is already prepared and available.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The page display process is segmented into multiple stages: data collection phase, data processing phase, and display phase. By separating these stages and allowing them to occur in different sequences or parallel, the system can collect data from multiple control devices simultaneously and process it concurrently, reducing overall page display time while maintaining data accuracy.

Inventive Principle:

Principle #1Segmentation

2Loss of information

If data collection from control devices is performed for each page display, then data freshness is improved, but communication load increases

Engineering Contradiction:

Improvedata freshnessVSAvoidcommunication load

Core Design Contradiction:

Loss of informationVSLoss of energy

Solution Approach 1:

The system performs preliminary data collection from control devices before the user actually requests page display. By collecting data in advance and preparing it for display, the system ensures data accuracy is maintained while significantly reducing the time required when the user actually requests the page, as the data is already prepared and available.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system maintains continuous data collection and processing in the background, even when no page display is requested. This continuous action ensures that data is always fresh and ready for immediate display when needed, while the intelligent scheduling ensures communication with control devices occurs efficiently rather than repeatedly for each display request.

Inventive Principle:

Principle #20Continuity of useful action

3Manufacturing precision

If complete data processing is performed before page display, then display accuracy is improved, but manipulation speed decreases

Engineering Contradiction:

Improvedisplay accuracyVSAvoidmanipulation speed

Core Design Contradiction:

Manufacturing precisionVSSpeed

Solution Approach 1:

The page display process is segmented into multiple stages: data collection phase, data processing phase, and display phase. By separating these stages and allowing them to occur in different sequences or parallel, the system can collect data from multiple control devices simultaneously and process it concurrently, reducing overall page display time while maintaining data accuracy.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system dynamically adjusts the data collection and processing based on the specific page being displayed and the user's interaction patterns. Frequently accessed pages have their data collected and processed more aggressively, while less frequently accessed pages use on-demand collection. This dynamic approach ensures display accuracy for important pages while improving overall manipulation speed.

Inventive Principle:

Principle #15Dynamics
