SCADA Historical Data Replay Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing physical control systems, such as SCADA systems, face challenges in efficiently displaying and analyzing historical data, leading to difficulties in identifying operational issues, comparing data over time, and performing diagnostic tasks due to spatial limitations and the need for multiple navigational steps.
Innovation Solution
A device and method that process user selections for screen replay options, retrieve historical data, and update the user interface to modify the appearance of graphical representations of physical components based on the retrieved data, allowing for the replay of historical data at defined speeds and enabling concurrent display of operator actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If historical data is displayed using traditional SCADA interfaces, then data can be viewed, but multiple navigational steps and spatial limitations prevent efficient analysis and identification of operational issues
Solution Approach 1:
The patent combines multiple data views (real-time data, historical data, operator actions, geographic information) into a single unified display interface. This merging eliminates the need for multiple navigational steps between different screens or windows, allowing operators to analyze historical data efficiently while seeing all relevant information in one location.
Solution Approach 2:
The patent adds temporal dimension to the display by showing historical data replay alongside real-time data in the same interface. The ability to replay historical data at defined speeds and overlay it with current operational state creates a multi-dimensional view that enhances analysis without requiring additional navigational steps.
2Loss of information
If historical data is displayed in detail, then operational issues can be identified, but spatial limitations prevent comprehensive display without multiple windows or screens
Solution Approach 1:
The patent merges multiple information layers (historical data, real-time data, operator actions, geographic relationships) into a single integrated display. This allows comprehensive information presentation within limited screen space by overlaying and combining different data types rather than requiring separate windows or screens for each.
Solution Approach 2:
The patent utilizes temporal dimension to display historical data replay alongside real-time data, effectively adding a time axis to the spatial display. This allows comprehensive data presentation without increasing physical screen area, as historical and current data coexist in the same visual space at different temporal references.
3Reliability
If real-time data is displayed continuously, then current operational state is monitored, but historical data analysis requires switching to different views losing real-time context
Solution Approach 1:
The patent merges real-time monitoring and historical data analysis into a single interface that maintains continuous real-time data display while enabling historical data replay. Operators can analyze historical events without switching views, as the replay functionality is integrated into the same screen that shows current operational state, eliminating navigation time and maintaining contextual awareness.

AI summary
An improved physical control system environment that allows an operator to replay historical data in a user interface that depicts content as if the data being displayed in the user interface is being captured or measured in real-time is described herein. For example, the improved physical control system environment can produce an improved user interface that depicts graphical representation(s) of one or more physical components optionally arranged by geography, similar to the graphical representation(s) that are depicted by a physical control system user interface that displays real-time data. However, the underlying data depicted in the improved user interface may be historical data rather than real-time data. The improved user interface may display the historical data in association with the appropriate physical component graphical representation(s), with the appearance of the graphical representation(s) changing in size, shape, color, or other form based on the historical data and at a user-selected speed.
