Information Modeling of Communication in Digital Grid system Based on BIM Technology

In order to promote the construction of communication system in the digital grid and the sharing of information of the whole life cycle of the communication system in the digital grid, the basic framework of the information model of the communication system in digital gridwork is designed and constructed based on the full consideration of the objects and information composition at each stage. The basic components of the information model are defined, and the information model is elaborated in terms of geometry and properties based on the Industry Foundation Class (IFC) standard. In this study, the communication unit is taken as the instantiated object of the information model, the characteristics of the job structure and the expression of the spatial structure in the communication field are combined. The relationship between the whole system and the components of the communication engineering unit is established. By extending the classical Building Information Model (BIM), the information model of the communication system in digital grid based on IFC standard is constructed, which provides a reference for the promotion of BIM technology in the field of digital grid.
