ABSTRACT
This study proposes a remote scour monitoring system especially focusing on ambient vibration monitoring as an alternative method for the conventional impact test. The remote scour monitoring system consists of an edge computing system, wireless communication and cloud computing. The ambient vibration signals are processed and the target frequency is identified in the edge computing system. The identified frequencies are sent to a cloud computing system via mobile telecommunications. In the cloud computing, possibility of scour is estimated and warnings are sent out. A stochastic warning index is proposed for alarming the scour event because of relatively poor signal to noise of the ambient vibration signals comparing to that from the impact test.
