Research On Development And Prediction Model Of Dam Safety Monitoring Information System Based On BIM

Our country has built a large number of water conservancy projects to optimize the allocation of water resources and promote the coordinated development of the region.Among them,reservoir dams have created huge benefits in flood control,water supply,irrigation,power generation,and shipping.Dam safety monitoring is an important prerequisite for ensuring the safe operation of dams.There are many dam safety monitoring projects,the spatial distribution of monitoring points is complicated,the collection and management of monitoring information is heavy,and the large amount of collected monitoring data needs to be managed and analyzed in a timely manner.In order to more effective safety monitoring work,fully grasping the running state of the dam,this article is based on BIM technology,combined with Visual Studio and C # language,on the second development,set up management,monitoring instrument,which can realize the dam structure monitoring data management and analysis functions such as monitoring data to predict the dam safety monitoring information system,According to the characteristics of monitoring data,the prediction model of the embedded system is studied.The development of the dam safety monitoring information system is based on BIM technology,combined with Visual Studio development environment and C# development language,the secondary development of Revit is carried out to build the dam safety monitoring information system.The dam structure management module uses the powerful 3D modeling ability of Revit software to build a 3D model of the dam,and through the operation of material parameter setting,roaming,rendering and 2D section,the global and detailed characteristics of the dam can be truly displayed.The monitoring instrument management module establishes the three-Uygur model of the monitoring instrument according to the entity of the monitoring instrument,displays and manages the attributes of the monitoring instrument,and utilizes the monitoring instrument family model to efficiently complete the layout of the monitoring instrument in the system.The monitoring data management module combines Visual Studio and C# language to realize the interaction between Revit and the database.The three-dimensional model of the monitoring instrument and the command button are adopted to establish the association between the monitoring items and the monitoring data.The monitoring data analysis module studies the construction of the wavelet BP neural network model.First,the wavelet analysis is used to de-noising the monitoring data containing noise pollution,then the BP neural network model is established to model the de-noising data,and the model is embedded into the system to realize the analysis and prediction of the dam safety monitoring dataThe research and development method and process of the system are discussed in detail with an example.The established safety monitoring BIM information system integrates the above four functional modules,realizes the three-dimensional visualization of monitoring work and the efficient management of monitoring information,and the built-in prediction model established by the research has achieved ideals effect.
