Design Of Health Monitoring System For Large-scale Grid Structure

With economic development, the need for structural health monitoring of structures become more and more popular, the development of a variety of public interest especially of grads structure appear more important. In this context, an intelligent real-time accurate monitoring system is necessary.Nowadays, many domestic and international large-scale grids structure used in the monitoring framework, however, There are many of them there is a big limitation of the design, for example, the slowly acquisition speed, the less precision collecting and the higher assumed costs. In this paper, more advanced wireless sensor network technology has been adopt. Compared with traditional cable collection systems, it cost savings and also can avoid unnecessary interference to collect more accurate results, while friendly interface and optimized programming. Allows the system to achieve low power, high acquisition speed and high precision acquisition.To achieve the goal above, this paper completed the following work:I introduce the Grid monitoring system of grids structure's domestic and foreign health status, and summarize the research progress now and the weakness. for the goals of this paper,I introduce the main work of and results.Firstly, to confirm the overall framework of system hardware, choose the devices to ensure low power and precision work of hardware systems.Secondly, design data processing wireless sensor nodes with capacity of design sensor network collecting data, while the design of distributed data collection of multi-channel sensor network, real-time data acquisition and processing.Finally, with a powerful and user-friendly man-machine window, you can store historical data, made statements and print., and also can analyze the real-time data and alarm.
