Technical Field

[0003] However, existing 3D electrical design systems have the following technical shortcomings: (1) Low degree of multimodal data fusion: The existing system can only process single type of data (such as drawings or 3D models), and cannot achieve deep fusion of multi-source data such as drawings, 3D point clouds, and operation and maintenance data, resulting in a lack of comprehensive data support for design decisions; (2) Limitations of knowledge graph application: The knowledge graphs of existing systems mostly contain only single-dimensional knowledge such as equipment parameters, and do not integrate three-dimensional spatial relationships, full life cycle operation and maintenance data and industry standards. Furthermore, they cannot achieve cross-modal association with image features, resulting in weak knowledge service capabilities. (3) Design and operation and maintenance are separated: the existing system only focuses on modeling and drawing in the design phase, and does not feed back the defect data and equipment life data in the operation and maintenance phase to the design process, resulting in the lack of full life cycle optimization of the design scheme and a high risk of failure in the equipment operation phase; (4) Insufficient collaboration and practicality: The existing system lacks standardized collaborative interfaces for hardware and software components, resulting in low data interaction efficiency. Furthermore, the component combinations have not been optimized for core requirements such as compliance verification and intelligent selection in electrical design, and the design efficiency and accuracy need to be improved.
