桥梁结构监测数据预处理方法及其应用

Research on Method of Data Preprocessing and Its Application for Bridge Structural Monitoring

介绍了桥梁结构监测数据预处理的几种方法,并基于九江大桥健康监测系统,对系统采集的数据首先选用其中的两种数据预处理方法,分别判别数据中的异常值,剔除粗大误差,其次采用数据平滑方法对噪声数据进行处理,采取这些合理的数据预处理方法最终可以获得对桥梁结构健康状态评估起重要作用的有效数据.

This paper introduces several methods of monitoring data preprocessing for the bridge structure. Based on Jiujiang Bridge health monitoring system, firstly, choose two kinds of data preprocessing methods from the data collected by the system are chosen; abnormal data is discriminated respectively and the bulky error is eliminated. Then the noise data is processed by the smoothing method. Finally, these reasonable data preprocessing methods are used to get the effective data which plays an important role in the bridge structure health condition assessment.
