Large-scale Automation Of Bridge Health Monitoring And Safety Assessment

Bridge Health Monitoring System is the developing trend of long-span bridge safety ensuring system. Associated with the project, the research on monitoring automation and safety evaluation of bridge structure is investigated in this paper. The program of the whole monitoring system is put forward, and the software design and development is also accomplished.Based on the objective and functional requirement of establishing the Bridge Health Monitoring System, the load characteristic of specified bridge style is analyzed and the monitoring program is formed by step in the paper. Moreover, the construction process of monitoring system is described in detail.In order to meet the need of data acquisition and data transfer, an application of data acquisition is developed to generally control and configure the acquisition equipment. It acquires monitoring data automatically, and other supplied functions include testing the equipment, user-defining the acquisition mode, altering the sampling interval, remote data transfer, and so on.According to the user requirement analysis, the computer software implemented data management and safety evaluation has also been designed and developed. It provides classifying management of monitoring data, displaying the query result with chart and table, data calculation and processing, and other functions. A method of safety evaluation combined Analytic Hierarchy Process and Artificial Neural Network algorithms is advanced in the paper, and the corresponding software function is achieved too.
