The Design And Implementation Of Data Analysis And Display Subsystem Under Slope Deformation Monitoring Platfrom Of Beijing-shenyang DPL

The roadbed is a significant part of the railway line,and one of the critical factors influencing the stability of roadbeds is the railway slope.\When the train passes,the vibration of the roadbed structure will cause the deformation of the subgrade.Once the deformation is irreversible and beyond the threshold,it will pose a threat to the safety of the track.In addition,railway slopes are vulnerable to weather and geographical factors such as rainfall,weathering or earthquake,which would undermine the train safety.China North Industries Group Corporation Limited(CNGC)takes the lead in applying the BeiDou Navigation Satellite System(BDS)high-precision positioning technology which is being rapidly developed.The deformation monitoring platfrom for railway subgrades,slopes and landslide areas is established to effectively monitor and provide early warning for all kinds of hazards and disasters.The research project of this thesis is the data analysis and display subsystem under the slope deformation monitoring platform for the section of the dedicated passenger line from Beijing to Shenyang(Beijing-Shenyang DPL).The system realizes the reception and further calculation of the slope deformation monitoring data,and displays the data in the front interface of the Web through the UI design scheme which provides a good user experience.The first part of this thesis introduces the relevant project background,research status and significance.The second part introduces the technology involved in the subsystem development.The third part explains the basic requirements of this subsystem,and summarizes the overall design of the project,introduces the design of database and interface UI.Subsequently,the project module is categorized in terms of functioning structure and the detailed design process and implementation results of the key modules are analysed.Last but not least,it summarizes the technological efforts thusfar and forecasts the prospective development of this research.This thesis mainly introduces the key modules' design and implementation processes of data analysis and display subsystem under slope deformation monitoring platform of Beijing-Shenyang DPL.The key modules including the site receiving module,the data refinement processing module,the site monitoring module and the system management module.
