Development And Application Of Building Deformation Monitoring Data Management System Based On WebGIS

In recent years,the social economy at home and abroad has developed rapidly,construction technology has advanced by leaps and bounds,and the scale of construction has been increasing day by day.The safety of buildings during construction and operation has received more and more attention.The most important factor affecting building safety is its own deformation.Therefore,deformation monitoring during the construction and operation phases of the building is necessary.The large-scale engineering deformation monitoring project has the characteristics of wide monitoring area,many monitoring points and long monitoring period.Therefore,a large amount of deformation monitoring data will be generated during the deformation monitoring process.If it is managed by conventional manual or simple files,it is not only inefficient,high error rate,but also the data display is not intuitive and vivid.At the same time,it is not convenient for data exchange and sharing,and it is difficult to meet the requirements of information construction and intelligent management.In order to adapt to the characteristics of the current deformation monitoring project,it is imperative to establish a universal data management and query system for data storage,processing and monitoring data visualization and data sharing.From the perspective of data sharing,this thesis adopts the extended architecture based on B/S architecture mode as the overall framework of the system,and designs and implements the WebGIS building deformation monitoring data management system.In this process,this thesis discusses and analyzes the related technology of real-time processing of building deformation monitoring data and Web graphic technology based on deformation data,and calls online image service to display monitoring points and control points clearly and visually on the image.The plane position makes the building deformation monitoring data management automation,early warning automation,deformation data visualization,and report automation.Finally,the deformation monitoring data of a nuclear power plant is used to verify the robustness and availability of the system.
