BIM data access processing method

Abstract

The invention discloses a BIM data access processing method. The system supports access processing of various BIM data, including three-dimensional model data of building components, security and protection system personnel identity information and building internal Internet of Things data, such as a network sensor, a camera, an infrared sensor, a fire-fighting probe, an access control sensor, an intelligent water, electricity and gas meter and the like. A topological network is constructed by taking floors as units, and a unified building sensing network is established by taking space coordinates in a building as unique mark IDs (Identity) of various types of equipment. According to the method, BIM data is uniformly divided into three types of 3D model data, sensing system data and personnel identity data, and during access processing, the 3D model data of a building is taken as a skeleton, and a uniform standardized BIM data format is established in combination with the unique mark ID. Besides, all kinds of information data are placed in a unified BIM database, wherein the access and calling of all kinds of data are managed by the BIM database in a unified mode.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a BIM data access processing method. Background technique [0002] BIM (Building Information Modeling) technology is a kind of virtual three-dimensional model of construction engineering established by digital technology, and at the same time, it provides a complete construction engineering information library containing geometric information describing building components, building attributes and status information on the basis of the model. , thus providing a platform for building management and information exchange and sharing for stakeholders. Theoretically, the BIM system can access, process and integrate all kinds of information inside the building on the basis of its own accurate three-dimensional building model, so as to realize the comprehensive management of the data of various subsystems such as security, energy and fire protection inside the whole building, and open up ...

AI Technical Summary

Problems solved by technology

However, in response to these problems, there is currently no unified BIM data access and processing method. In fact, the call and processing of various BIM data are limited to the subsystems where they are located, and the unified management of all BIM data cannot be realized. The acquired information cannot be linked, the operation efficiency is low, and the interconnection of all data information in the building cannot be truly achieved

At the same time, because there is no unified data processing method, the data model of the entire BIM system is bloated and the management is chaotic, which is not conducive to the access of new business data in the later period
