Abstract:

In order to solve the problems of the massive data preprocessing and storage about the bridge,we propose a data preprocessing and storage model for bridge which combines the advantages of the concept of distributed processing of large data,the data stream sliding window technology and wavelet packet processing for noise reduction.The model not only saves the raw data of bridge monitoring and integrate the data preprocessing into their storage,but also alarms when the sensor is stop working.The results show that it is feasible to apply the model in massive data preprocessing and storage in bridge health monitoring.
