Abstract

The invention discloses a BIM-based data processing method and apparatus for prefabricated building process design. The method comprises the steps of obtaining an original BIM file, wherein the original BIM file comprises multiple BIM entity objects forming a building model; analyzing the original BIM file, and extracting geometric topology information and attribute information of building elements in the original BIM file; based on the geometric topology information and the attribute information, performing data duplicate removal to generate a graph library object set with completely unduplicated sample graphs; obtaining the matched sample graphs in the graph library object set according to entity types for the original BIM file, and generating reference data of the BIM entity objects relative to the sample graphs; and storing the graph library object set and the reference data. The data is subjected to lightweight processing, so that the problem of relatively low BIM file display loading speed is avoided, the BIM file storage cost and the over-dependency on hardware are reduced, and the performance of a whole system is improved.

Description

technical field [0001] The invention relates to the technical field of prefabricated buildings, in particular to a data processing method and device for BIM-based prefabricated building process design. Background technique [0002] BIM design is the information basis for the industrialization of prefabricated buildings. The Ministry of Housing and Urban-Rural Development vigorously promotes BIM-based architectural design, which will have a profound impact on the architectural design market and models. Design based on BIM technology is the foundation of its building for the industrialization of construction. The accuracy of architectural structural process design results in a tenfold or hundreds of times increase in the amount of information compared to traditional building outline-based BIM design information, but limited by the existing computer memory capacity and CPU computing power, browsing too large design files is quite time-consuming , and even lead to the inability...
