Abstract

Structural Health Monitoring (SHM) that uses integrated sensor network to provide real-time monitoring of in-service structures can improve the safety and reliability of the structures significantly. Acellent Technologies' SHM systems based on SMART technology consists of the integrated sensor network, diagnosis hardware platform and the diagnosis software. This paper introduces the latest SMART damage detection hardware platform - ScanGenie and the new analysis software for damage detection in composite and metal structures. The ScanGenie is a portable high-performance hardware that provides many features such as through-transmission, pulse-echo, temperature measurement, self-diagnosis, sensor diagnosis, etc. The new analysis software is based on the ScanGenie hardware to provide functions such as temperature compensation, auto-gain adjustment, impedance-based diagnosis and probability of detection. The system can be used for damage detection in most composite and metal structures such as aircraft, spacecraft and civil infrastructures.
