ABSTRACT

Structural health monitoring deals with the more or less continuous recording of data obtained from the structure. Based It is obviously very helpful not to base an analysis on one physical quantity alone or on one sensor. The reliability of the monitoring system is fairly enhanced combining the information obtained at different sensor nodes. Further on, comparison of time series obtained by recording different physical quantities results in a drastic improvement of reliability and lowers the detection threshold of deterioration. Establishment of a correlation between data and structural performance is difficult and should be based on the data interpretation expertise of the user. This combination can be done even in terms of an intelligent pre-processing of data in the mote or in a cluster of motes which can additionally reduce the power consumption.
