Control Logic Diagram Drafting from Similar Plant Differences
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for creating control logic diagrams are inefficient, as they do not facilitate the draft proposal of a control logic diagram as a raw plan, despite being able to create diagrams using high-frequency parts.
Innovation Solution
A control logic diagram creation support apparatus that includes a plant information input unit, a plant information versus control logic diagram association information storage unit, a similar plant information retrieval unit, a plant information difference detection unit, and a plant information editing unit, which retrieves and edits plant information to detect differences and generate a draft proposal by associating and editing control logic diagrams based on similar plants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional logic diagram search techniques are used to create control logic diagrams using parts with high appearance frequency, then maintainability and productivity are improved, but the ability to generate draft proposals as raw plans remains insufficient
Solution Approach 1:
The system performs preliminary actions by automatically generating draft proposals of control logic diagrams based on plant information and similar plant data before the user begins detailed creation work. The draft proposal generation unit creates initial control logic diagrams that users can then refine, eliminating the need to start from scratch and enabling efficient draft proposal generation.
2Productivity
If control logic diagrams are created manually without automation support, then complete control can be maintained over each diagram, but creation efficiency remains low due to the large number of diagrams required
Solution Approach 1:
The system creates copies of control logic diagrams from similar plants by retrieving plant information and associated control logic diagrams from a database. The control logic diagram association information storage unit stores multiple control logic diagrams for each plant, and the draft proposal generation unit copies and adapts these diagrams for the target plant, significantly reducing creation time while maintaining quality through systematic reuse of proven designs.
3Stability of the object's composition
If control logic diagrams are created without systematic plant information management, then simple processes are used, but consistency and reusability across multiple diagrams deteriorate
Solution Approach 1:
The system implements universality by creating a integrated plant information management system that handles multiple functions: storing plant information and control logic diagrams in an associative database, retrieving similar plant data, generating draft proposals, and managing control logic diagram associations. This multi-functional system ensures consistency across all control logic diagrams through centralized management while reducing time loss through automated operations.

AI summary
For the purpose of obtaining a control logic diagram creation support apparatus for efficiently creating control logic diagrams, the apparatus includes: a similar plant information retrieval unit 13 that retrieves plant information of a similar plant similar to a creation object plant from plant information versus control logic diagram association information stored in a plant information versus control logic diagram association information storage unit 12; a plant information difference detection unit 14 that compares the plant information of the creation object plant with the plant information of the similar plant so as to acquire difference information; a plant information editing unit 15 that, based on the difference information, deletes an element included in the similar plant but unnecessary for the creation object plant, and retrieves an element included in the creation object plant but not included in the similar plant from the plant information versus control logic diagram association information storage unit 12 to add the retrieved element; and a plant information editing result display unit 16 that displays a result of the plant information editing unit 15.
