Abstract:
The purpose of this research and development is to realize structural health monitoring for increased efficiency in the maintenance of buildings and civil infrastructures, and observations to prepare for natural disasters, such as earthquakes. The most difficult and interesting issue is the realization of inexpensive time-synchronized measurements. It is necessary to install numerous sensors in a building or civil infrastructure and to acquire measured data whose time synchronization is ensured. Although Global Navigation Satellite System (GNSS) time information is generally only available outdoors, the authors designed a system capable of using GNSS time information indoors. This system can deliver time information to a building by using existing TV coaxial cables. The authors further developed a sensor device able to receive indoor GNSS time information and to add high-accuracy time information to measured data. This paper describes the development of a sensor device that adds high-accuracy time information to measured data by using a system to deliver GNSS time information indoors. The performance of the developed sensor device equipped with a mechanism for receiving GNSS signal-based time information was verified from the results of a shaking table experiment. It was shown that it can be applied to structural health monitoring of buildings and civil infrastructure and seismic observation.
