A BIM-based structural dynamic response safety monitoring system and method

Abstract

The invention relates to a structural dynamic response safety monitoring system and method based on a BIM, and the system comprises a structure response information integration module which is used for the integration and visualization of monitoring data based on a BIM platform; and a dynamic real-time safety monitoring module which is used for tracking the structural response of a key member during actual structural construction and application so as to dynamically monitor the structural safety state in real time, to timely give an alarm against a structural behavior abnormality and track andlocate the structural member that has an abnormality. The system and method solve a problem of dynamically tracking and monitoring the structural safety state in real time, improve the structural response and model interactivity, improves the safety monitoring level of the structural construction and application process, and provides a theoretical method and a feasible solution for the safety monitoring and early warning of actual engineering.

Description

technical field [0001] The invention belongs to the field of construction industry information technology, and in particular relates to a BIM-based structure dynamic response safety monitoring system and method. Background technique [0002] In order to ensure the safety of building structures and avoid losses caused by structural disasters, it is particularly important to carry out structural health monitoring. Structural health monitoring produces a large amount of data, which is a powerful basis for evaluating the service condition, reliability and durability of structures, and provides basis and guidance for structural repair, maintenance and management decisions. As the structure becomes more and more complex, the number of measuring points and sensor types for structural health monitoring are increasing, and the data volume is large and complex, which is difficult to understand. Therefore, it is necessary to improve the visualization level of monitoring data to make th...

Problems solved by technology

For example, use the method of IFC (Industry Foundation Classes, industrial foundation class) information expansion to create a sensor IFC expansion information model, and integrate the structural health monitoring data collected by the sensor into Revit. However, BIM software is generally commercial software, and the monitoring data is based on IFC. Format file integration and conversion process is prone to information loss; combined with XMP (Extensible Metadata Platform, extensible metadata platform) and IFC format files, the creation, processing and embedded customized data exchange are realized, and the structural health monitoring data collected by sensors are processed It is an IFC extension format, and the monitoring data can be integrated into the Revit platform with the help of XMP, but the data integration and transmission process is prone to distortion and errors due to multiple data conversions

In addition, relying on the IFC standard, IFC JAVA TOOLBOX can be used to call the data collected by the structural health monitoring system and extract the relevant attributes of the building components from the IFC file, and associate the monitoring data with the BIM model on the Revit platform. However, using the IFC standard only It can meet the definition of common attributes of components, so the monitoring data association model cannot fully meet the actual needs

Based on the vector space model to classify the text information of the data collected by the sensor, use the Revit API to extract the attribute information of the BIM model object and generate a query vector, and integrate the sensor monitoring data into the Revit model by adding the reference of the external resource vector space model, but this method only Verify the feasibility of its method in Revit software
