A BIM-based 4D operation and maintenance information model establishment method

Abstract

The invention belongs to the technical field of bridge maintenance data processing, and discloses a method for establishing a BIM-based 4D operation and maintenance information model, adding inspection batch attributes to form a time series of disease information in the text storage process; obtaining all conventional models Patrol batch information list; use logic to judge node patrol batch information column items, and output their Boolean value list; use the output Boolean value list to filter in all graphics entities; screen the filtered patrol batch graph The elements are colored and marked, and combined into a standardized module; the Code Block module is used to connect each standard module in series and controlled uniformly; the parameter values ​​of the batches in the control module are modified in turn to obtain the derivation sequence of the cracks; The update and association of secondary 4D information. The invention realizes the gradual change display of the disease information arranged in time series, and realizes the dynamic correlation between the disease information and the three-dimensional graphics.

Description

technical field [0001] The invention belongs to the technical field of bridge maintenance data processing, and in particular relates to a method for establishing a BIM-based 4D operation and maintenance information model. Background technique [0002] At present, the closest existing technology: the traditional bridge maintenance process, data such as disease information are recorded in the form of two-dimensional or three-dimensional data, and the disease information that is recorded and displayed is mainly the type, size, and location of the disease. When bridge managers process disease information, it is difficult to intuitively understand the order and internal relationship between diseases and diseases in time. At this time, if time parameters can be introduced to form a visualized disease time series, then bridge managers can analyze the derivation rules and preventive measures of the disease based on the change of disease shape, size, and location over time.

AI Technical Summary

Problems solved by technology

[0003] To sum up, the problem existing in the existing technology is that it is difficult for the existing bridge managers to intuitively understand the occurrence sequence and internal relationship between the diseases and the diseases in time when the existing bridge managers process the disease information, so as to realize the relationship between the disease information and the 3D graphic elements. Visualize the dynamic correlation and disease derivation law in the time series, and further analyze the derivation law of the disease and formulate preventive measures based on the change of disease shape, size, and location over time

[0005] In fact, the application of BIM technology in the current bridge engineering field is very limited. The application of BIM technology in new projects is still in the exploratory stage, and the actual application cases in the operation and maintenance stage are even scarcer, and there is no mature technology application route; Bridge BIM Software is lacking. Although there are many BIM design software manufacturers, there are not many design software for bridge engineering. The existing design software cannot meet the actual needs of bridge BIM modeling. In professional coding, data storage, transmission, identification, reading, Display and other aspects have varying degrees of difficulty; BIM technology itself is a highly cross-cutting information technology, and the operation and maintenance phase involves the joint application of multiple systems, including GIS systems, health monitoring systems, maintenance management systems, etc. How to integrate BIM technology makes it perfectly fit the actual needs of bridge operation and maintenance work, but it also poses new technical problems for bridge workers
