A digital transfer system that can achieve information sharing and facilitate collaborative work among all participating construction units, enabling the digital transfer of logical models, 3D models, design products, procurement documents, constructiondocuments, manufacturer materials, installation and commissioning materials, etc. Moreover, it can take the project object as the core, data as the foundation, and coding as the link. Realize the organic association of engineering data, logical models,3D models, drawings, materials and other information, so that project stakeholders can browse visual and multi-dimensional engineering information through this system, facilitating the query of engineering information, construction progress management,material management and other work, and is an effective means to improve the knowledge management and technical training of power plants.
