Predictive Operation Guidance Interface for Industrial Plant Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In conventional plant monitoring and control systems, operators face increased operational burdens due to the need for repeated screen transitions when checking data across multiple facilities, particularly during urgent situations like accidents, leading to inefficiencies in data checking time.
Innovation Solution
A graphical user interface device with an operation recommended button selecting device that uses pattern matching processing to predict subsequent operations based on operation procedure template data and plant measurement data, reducing the need for screen transitions by displaying guidance information for subsequent operations directly on the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If operators check data across multiple facilities by repeatedly transitioning between initial screen and detailed data display screens, then they can access target data items, but the time required for checking data increases significantly
Solution Approach 1:
The system performs preliminary actions by automatically displaying anticipated subsequent operation screens before the operator actually requests them. The screen transition prediction device analyzes current screen display and operation history to pre-load and present relevant detailed data screens, so when operators need to check data across facilities, the information is already prepared and displayed, eliminating the need for manual screen transitions and reducing data checking time
Solution Approach 2:
The system implements skipping by automatically bypassing intermediate screen transition steps. Instead of requiring operators to manually navigate from initial screen to detailed display screens and back, the prediction device identifies the target detailed screen and directly presents it, allowing operators to skip unnecessary navigation steps and access target data items more efficiently
2Productivity
If conventional hierarchical screen configuration with reciprocal links is used, then screen transitions can be managed systematically, but operators face increased operational burden during urgent situations
Solution Approach 1:
The system applies self-service by enabling automatic screen transition prediction and recommendation without requiring operators to manually navigate through hierarchical screens. The prediction device autonomously analyzes operation patterns, identifies anticipated next screens, and presents them to operators, allowing the system to serve itself in managing screen transitions rather than relying on complex manual navigation procedures
Solution Approach 2:
The system implements feedback by continuously monitoring operator operations and using this information to improve screen transition predictions. The prediction device analyzes operation history and current screen context to generate accurate predictions of subsequent screens needed, creating a feedback loop where past operations inform future screen presentations, thereby improving operation efficiency while managing system complexity

AI summary
In a large-scale plant such as a power plant, a graphical user interface device displays a target data display screen without increasing a load of searching a screen or a load of grasping a screen transition link. An operation model-creating device reads operation manual data for operation estimation and operation history data from an operation manual managing device and an operation history managing device to create a number of pieces of manual procedure template data for each accident type. An operation predicting device selects the operation procedure template data having same conditions of immediately preceding operation history data obtained from the plant monitoring and control device to predict the next operation estimated to be performed by an operator from the selected operation procedure template data. The plant monitoring and control device displays a system recommended operation button on a monitoring screen thereof based on data of the predicted results.
