BIM-based modeling method and device

The invention discloses a BIM-based modeling method. The method includes the steps that ontology parameters, including the number of areas and the types of areas, of a target data center are acquired;professional design standards corresponding to the ontology parameters are selected from a preset database; according to the professional design standards, the types of devices needing to be placed in each area of the target data center and the number and parameters of each type of devices are determined, and a power infrastructure BIM of the target data center is generated, wherein the professional design standards at least include natural design standards and industrial design standards of the decoration, power supply and distribution, lightning protection grounding, integrated wiring, air-conditioner fresh air, integrated monitoring and fire protection professions. Thus, by pre-storing the professional design standards in the database, the working efficiency of designers is improved, resources and costs are sa
