Engineering data association method based on improved Gaussian mixture model

Abstract

The invention discloses an engineering data association method based on an improved Gaussian mixture model, and the method comprises the following steps: S1, obtaining engineering data, and decomposing the engineering data to obtain job numbers; s2, encoding the job number to obtain a standardized code, and constructing a work decomposition structure code library; s3, building a building information model according to the engineering data; s4, importing the standardized code into the building information model; s5, analyzing the building information model to obtain component data; s6, constructing a Gaussian mixture model, and performing training and unsupervised learning to obtain an improved Gaussian mixture model; s7, clustering and grouping the component data by using an improved Gaussian mixture model; and S8, associating the component data with the standardized codes to obtain associated component data. Through the improved Gaussian mixture model, the engineering data volume and standardized coding participating in association at the same moment are reduced, and the efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of engineering data processing, in particular to an engineering data association method based on an improved Gaussian mixture model. Background technique [0002] BIM model, also known as building information model, is a new tool for architecture, engineering and civil engineering. The core of BIM is to establish a virtual three-dimensional model of architectural engineering and use digital technology to provide a complete architectural engineering information library for this model that is consistent with the actual situation. The information base not only contains geometric information, professional attributes and state information describing building components, but also contains state information of non-component objects (such as space and motion behavior). With the help of this 3D model containing construction engineering information, the degree of information integration of construction engineering ha...

Problems solved by technology

Moreover, due to the low correlation efficiency, it is impossible to realize the fine management of engineering projects, which leads to low management efficiency; and because the general engineering projects are large and the amount of data is large, the amount of correlation calculation is large, which affects the engineering efficiency.
