Abstract: Under the background of IFC railway standard research project, this paper focused on the research of data storage standards in railway communication field. According to the actual needs of railway communication engineering, the decomposition architecture of IFC railway communication system was proposed. The data requirements of the specific components in the field of railway communication were defined by the object-oriented concept, and the basic data description of the information model of railway communication engineering was implemented. It provides technical support for data storage, sharing and application in the whole life cycle of railway communication engineering. The research methods and results can be used for reference in other related fields.
