Embodiment
[0062] Step 1: Summarize and obtain the four railway engineering entities. "Railway Engineering Information Model Classification and Coding Standards" will be divided into four majors: communication engineering, signal engineering, electric power engineering, and electrification engineering from a professional perspective. This coding standard is the basis for studying the four electrical engineering entities. The railway four-power engineering entity will be applied to the entire life cycle of railway engineering construction, such as planning, design, construction, operation and maintenance, and needs to meet different types of railway engineering projects.
[0063] Step 2: Further summarize according to the characteristics and commonality of the four railway engineering entities. From the functional point of view, the unit entity is divided. The unit entity is the main component of the railway four-electric project. It can complete a certain function alone, and can also def...

The invention relates to a method for creating IFC4 entity information and a spatial position conforming to railway four-electric engineering. The method mainly comprises the following steps: concluding and acquiring a railway four-electric engineering entity; further concluding according to the characteristics and generality of the railway four-electric engineering entities, and defining the classes of the railway four-electric engineering entities from the functional perspective, the spatial inclusion relation perspective and the geometric spatial characteristic perspective; defining main attributes of the railway four-electricity engineering entity class; defining an association relationship among the railway four-electricity engineering entities; performing concept modeling on the relationship by using a universal visual modeling language UML class diagram; and fusing the UML conceptual model into the large framework of the IFC. According to the invention, newly added or expanded railway four-electricity engineering entities are analyzed and classified; a UML entity model is established, entity attributes are defined, so that an overall UML conceptual model is generated, IFC isfinally carried out on the overall UML conceptual model, and a method is provided for creating compliance check meeting railway four-electricity engineering IFC4 entity information and spatial positions and carrying out railway four-electricity engineering BIM detection.
Description
technical field [0001] The invention belongs to the technical field of railway four-electricity engineering informatization and railway four-electricity engineering BIM detection technology, and specifically relates to a method for creating IFC4 entity information and spatial positions conforming to railway four-electricity engineering. Background technique [0002] The construction technology of high-speed rail is constantly moving towards intelligence and informatization. The construction of the four railway projects (including: communication engineering, signal engineering, power engineering and electrification engineering) gradually uses BIM (Building Information Modeling) technology, which is of great significance to railway construction. Huge development potential and application value, but the existing BIM standards and BIM software platforms are basically oriented to the field of civil construction, and there are no standards and software platforms suitable for railwa...
