Interactive sensor data retrieval and management method for integrated structural health monitoring system

摘要

Transmitting the huge amount of monitoring data to central data processing station via communication channels with limited bandwidth might cause significant time delay.Innovative sensor data transmission and retrieval techniques are thus needed to enable fast and efficient transmission of sensor data.Furthermore,the huge data size increases the burden on data processing and analysis which may be necessary only for selected sensor data since data users such as engineers or decision makers might have different interests in retrieving sensor data with different resolutions during different time periods.This paper presents the concept of such an integrated SHM system which has a few important functionalities including sensor data compression,interactive data retrieval and data management,and second order structural parameter identification.A prototype integrated SHM system is described in this paper and its performance was examined using real sensor data.
