Description

Technical Field

[0001] The present application belongs to the technical field of digital experimental systems, and specifically relates to a unified data warehouse system applied to nuclear power engineering experimental systems. Background Art

[0002] The nuclear power engineering experiment system (also known as the nuclear power engineering digital experiment integrated application system) is a complex system that integrates multiple elements, including experimental personnel, experimental subjects, experimental equipment, experimental simulations, experimental operating procedures, and experimental operating parameters. Its complexity has always been a major factor hindering the development and innovation of nuclear power engineering experimental technology. Nuclear power engineering experiments are highly technical and highly interdependent among various elements in the system. They involve the coordination and coupling of multiple departments, tasks, disciplines, and tools, and are subject to harsh operating conditions such as high temperature and high pressure. Therefore, the reliability and safety of experimental operations must be fully considered. Therefore, to establish an efficient business execution environment for nuclear power engineering experiments, it is necessary to integrate the tasks, tools, knowledge, and data related to nuclear power engineering experiments within a unified framework, achieving coordination and coupling across stages, departments, tools, and systems. Through the nuclear power engineering experiment system, a unified and efficient digital business execution environment applicable to the entire life cycle of nuclear power engineering experiments can be established.

[0003] "Research on the Application of System Engineering Methodology in Nuclear Reactor Digital Experiments" explains the top-level architecture of the digital experiment platform, including the business process architecture composed of the V model and business scenario diagram. Although it mentions the platform functional layered architecture composed of the business management system at the business layer, the experimental design and simulation collaborative workbench system at the application layer, the experimental knowledge system at the knowledge layer, and the basic functional system at the resource layer, it only studies the basic theory of digital experiments from the perspective of system engineering, and does not elaborate on the specific structure of the comprehensive application system of nuclear power engineering digital experiments.

[0004] Current experimental database systems for nuclear power engineering experiments typically use data fields and tables to display experimental background, technical documentation, experimental equipment, experimental conditions, and experimental data. These systems lack graphical methods for viewing and correlating the relationships between experimental equipment, measurement points, and experimental data, and they also make it difficult to dynamically replay experimental runs. Current experimental database systems typically manage various data types using data fields and manual classification. They lack multi-view methods for viewing or tracing data from different dimensions. Summary of the Invention
