Design And Implementation Of Bridge Health Minitoring Data Presentation System

Bridge structure health monitoring system is the main way for monitoring Bridge security operation, Bridge health monitoring data presentation system is a part of the bridge monitoring system, it is known as an important tool for bridge management and maintenance staff to judge the whole bridge health status. Therefore, Bridge health monitoring data presentation system plays an important role. This paper, taking a across ocean big bridge health monitoring and evaluation diagnosis project in a Municipality as the background, design the client bridge structure health monitoring data presentation system using c#programming language and Visual Studio.NET development environment for development, and with the aid of Dundas Chart for. NET and Dundas Gauge for.NET instrument as a support to implement the functions of data presentation system interfaces. Finally, realizing the real-time monitoring of the front-end data acquisition system and graphic Visual display, thereby for the bridge health diagnosis and early-warning, etc.On the research theme and purpose, this paper mainly completed the following several aspects: On the basis of studying the development situation of bridge health monitoring system and for the target requirement of the system, this paper determines the main monitoring indicators of Bridges, and thus chooses sensors.According to the requirements and characteristics of this Bridge health monitoring data presentation system, this paper determines the suitable data display mode for this subject, thus to build Bridge health monitoring data presentation system organization architecture. Then according to the need of the system function realization, this paper designs respectively the interface of bridge monitoring state, Fiber Bragg Grating (FBG) demodulation instrument interface, fiber Bragg grating stress/temperature interface and the Art interface. Last, Through processing, storage and presentation acquisition of data,this paper achieves the purpose of real-time monitoring of the bridge health status, not only fully reflects the design of the system both in skill and ease, also meets the practical needs of users.This paper uses support of the powerful SQL Server database to implement the historical data storage, and discusses how to realize observing history acquisition data in view of the acceleration sensors through the SQL Server database, then achieves the plot of the data time, and makes the correlation analysis of data signals. Then discusses how to realize observing history acquisition data in view of the Fiber Bragg Grating (FBG) sensors and draw the data temporal curves, thereby achieving the goal of data analysis directly and strikingly.
