Description

A kind of structure dynamic response safety monitoring system and method based on BIM
Technical field
The invention belongs to Information industry technical field, and in particular to a kind of structure dynamic response based on BIM is supervised safely Examining system and method.
Background technology
To ensure the security of building structure, avoid structure that loss caused by disaster accident, progress structural health prison occurs Survey is particularly important.Monitoring structural health conditions produce mass data, these data are military service situation to structure, reliability and resistance to The strong foundation that long property is assessed, foundation and guidance are provided for the maintenance, maintenance and administrative decision of structure.As structure becomes More sophisticated, the measure-point amount and sensor type of monitoring structural health conditions are more and more, and data volume is big and complicated, it is difficult to understand, Visualization therefore, it is necessary to improve monitoring data is horizontal, makes monitoring data intuitively readily understood.
Building Information Model (BIM, Building information modeling) be it is a kind of be applied to structure design, The digitizing solution built and managed, can be to work by all real informations of three-dimensional digitalization model simulant building thing The complete description of journey object, can understand project parties and comprehensively understand project.BIM models are a kind of three-dimensional visualization and ginseng Numberization model, can provide Visualization Platform for the information in project each stage, obtain with enabling project parties quicklook required Information, so as to greatly improve man-machine interaction and work efficiency.An important stage of the monitoring structural health conditions as project, can be with The visualization of monitoring information is realized with BIM visualization techniques, it is directly perceived to show structural response information, reduce monitoring data and understand hardly possible Degree, improves the efficiency of decision-making, so as to better ensure that structure safety.BIM platform softwares are numerous, and wherein Navisworks is at present should With most commonly used BIM kernel softwares, there is powerful model integration and Visualization ability.Navisworks is provided out The API put, can develop the needs that corresponding function module meets actual items.
In recent years, domestic and international researcher is made that just in terms of the integrated and visualization of data is carried out based on BIM platforms Step research.The method such as expanded using IFC (Industry Foundation Classes, industrial foundation class) information, is created and passed Sensor IFC expands information model, and by the monitoring structural health conditions data integration of sensor collection to Revit, but BIM softwares are generally all It is commercial software, monitoring data are integrated with IFC formatted files loss of learning easily occurs with transfer process;With reference to XMP (Extensible Metadata Platform, extensible meta-data platform) and IFC formatted files, realize establishment, processing With embedded customization data exchange, the monitoring structural health conditions data processing of sensor collection is expanded into form for IFC, by XMP Achievable monitoring data are integrated into Revit platforms, but the integrated and transmittance process of data easily occurs due to multiple data conversion Distortion and mistake.In addition, relying on IFC standards, IFC JAVA TOOLBOX can be used to call structural healthy monitoring system collection Data and the association attributes that building element is extracted from IFC files, by monitoring data and BIM models on Revit platforms it is related Connection, still, the definition for meeting component general-purpose attribute is only capable of using IFC standards, causes monitoring data correlation model to expire completely Sufficient actual demand.Classified based on vector space model into line sensor gathered data text message, extracted using Revit API The attribute information of BIM model objects simultaneously generates query vector, by adding the reference of external resource vector space model, will sense Device monitoring data are integrated into Revit models, but this method is only in the feasibility of its method of Revit software verifications.
The content of the invention
The studies above realizes structure monitoring data integration and management based on BIM platforms, but still has asking for some keys Topic needs to solve.Data conversion and it is integrated during meet ad hoc rules frame by force and information easily occur because of multiple processing data Missing and mistake, and data message with BIM model associated procedures because the limitation of IFC normative document general-purpose attributes has been difficult to All demands of full up foot actual items, it is necessary to based on open API Secondaries, directly invoked in the form of plug-in unit The monitoring data of health monitoring systems collection, and the structure security information of polymorphic type form, avoid information integration and transmitted Occurs funneling effect in journey.Moreover, integrated subject table only relies on collection of the structure security information in the single softwares of Revit Into, it is difficult to realize the safety monitoring of structure Life cycle, consider the advantage of BIM platform different softwares, it is necessary to comprehensively utilize, Navisworks and Revit is developed, promotes the safety monitoring based on BIM to land conscientiously, communicating structure safety monitoring is given birth to entirely in BIM Order the total solution in cycle.
