Research On Design And Application Of Io T System For Bridge Health Monitoring Based On Cloud Computing

The bridge structure has structural damage and functional degradation during long-term operation.Establishing a scientific structural health monitoring system can provide reliable support for bridge safety management.Traditional bridge health monitoring systems are mainly aimed at a single project,which has the problems of high construction cost,weak analysis ability and low level of information sharing.With rapid development and application of Internet of things(Io T)technology,establishing the Io T system for bridge health monitoring based on cloud computing,can greatly reduce the construction cost of the structural health monitoring system,improve the intelligent analysis ability for massive monitoring data,and promote the information sharing level of structural health monitoring,which can provide online support for safety assessment and decision-making of regional level bridge structure.This paper combines the advantages of Io T and cloud computing,and carries out the design and application research of the Io T system for bridge health monitoring.The main work is as follows:(1)The research background and research significance of the subject are introduced,the research status of bridge health monitoring system,Io T and cloud computing is expounded,and the characteristics and application prospects of structural health monitoring Io T are discussed.(2)From the perspective of information acquisition and information utilization,the overall architecture of the bridge structure health monitoring Io T system is proposed.Based on the analysis of system information flow,a technical solution for information management using a relational cloud database is proposed.Functional modules of the structural health monitoring cloud platform are formulated,which laid the foundation for modular design.(3)Research on key technologies of data acquisition control,storage,analysis and visualization in the cloud platform of structural health monitoring has been carried out.The data acquisition control strategy of the cloud platform is put forward,which realizes the remote platform-based data acquisition control.Using the information isomorphic storagestrategy,a cloud database structure is constructed to achieve reliable and efficient storage and management of monitoring information.Based on the mixed programming technology of ASP.NET and MATLAB,the development research of the analysis algorithm is carried out,which realizes the automation and intelligence of data analysis.The data visualization research based on Power BI is carried out,which realizes the visual display of monitoring information.(4)The experimental research on the construction of cloud platform for structural health monitoring is carried out.Based on the key technologies of the cloud platform of structural health monitoring studied in this paper,the cloud platform of structural health monitoring is developed,and the effectiveness of each key technology is verified.This research lays a good foundation for the construction of the cloud platform of structural health monitoring.(5)A case study of the structural health monitoring cloud platform of Xinguang Bridge is carried out.The Io T system for structural health monitoring is established,and the data acquisition control,storage,analysis and visualization of Xinguang bridge health monitoring cloud platform are realized.As the platform is implemented based on cloud computing,it is easy to update and maintain,with good security and scalability.This case study provides a reference for the establishment of the Io T system for regional bridge structural health monitoring.
