Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular, to a method and system for converting a water treatment process flow chart into a graph model. Background Art

[0002] A water treatment process flow chart is the core design drawing for designing and recording key information such as the engineering overview, unit composition, water flow relationship, water quality situation, unit process characteristics, and component composition of the entire water treatment process in water treatment;

[0003] In practical applications, the water treatment process flow chart still exists in the form of drawings in the process design link and cannot interact with modern computer software and hardware such as computer databases, design record query and analysis systems, and water treatment professional Q&A robots; while the graph model can clearly and intuitively express the connection relationship between process units and the composition relationship with engineering projects and components in a visual way, and its unique "subject-verb-object" data storage structure naturally has an innate advantage in coupling with natural language processing; the water flow relationship, the inclusion and being-included relationship between components and process units, and the combination of projects and process units in water treatment process design are also naturally the best implementation objects of the graph model;

[0004] Although there are patents on related model conversion methods published in the power system, such as patent CN117493432A, due to the uniqueness of the water treatment system and the dependence on the process flow chart in the design, coupled with a large number of complex and unique water flow topological relationships, it is impractical to directly transplant the graph model conversion methods of other industries; therefore, there is still a need to specifically construct a set of conversion methods and systems for converting a water treatment process flow chart into a graph model to meet the needs of the water treatment industry for digital and intelligent transformation.
