SINGLE CHANNEL CONDUCTIVE FABRIC TAPE PIEZOELECTRIC SENSOR NETWORK, DEVICE FOR DIAGNOSING DAMAGE BASED ON MULTI-SOURCE ULTRASONIC WAVE IMAGING, AND METHOD THEREFOR

摘要

The present invention provides a single channel conductive fabric tape piezoelectric sensor network, a device for diagnosing damage based on multi-source ultrasonic wave imaging, and a method therefor. According to an embodiment of the present invention, the system for diagnosing damage comprises: a sensor array installed in a structure and having ultrasonic sensors connected in series by using a conductive fabric tape; and an imaging system exciting laser to an inspection surface of the structure and collecting wire-wireless signals from the ultrasonic sensors to generate an ultrasonic propagation image. Therefore, the present invention overcomes limitations of an inspection area caused by the single sensor while diagnosing damage to the large structure, removes devices related to a cable required to from a multi-channel sensor network, and reduce the weight of the devices.;COPYRIGHT KIPO 2017
