Abstract

One of the essential challenges facing the research and development on structural health monitoring system for civil infrastructures has proven to be time synchronization among the huge number of sensors required. As a conventional technique for synchronizing the time among multiple sensors, GPS signals are available; however, these signals are not available in many places and below ground. To resolve this problem, autonomous sensing technology was established to ensure highly accurate time information using chip scale atomic clock (CSAC). In this study, fundamental research of the autonomous sensing technology using CSAC is introduced and performance evaluation test for the developed prototype sensing module is also presented.
