Preliminary design of a vibration monitoring system to be installed in an archaeological heritage structure: The case of the Hera temple (Paestum, S Italy)

Digital models are gaining an increasing popularity for the management of cultural heritage assets. In the context of preventive archaeology, digital models of heritage structures or infrastructures, integrated with a physical counterpart, consisting in a structural monitoring system, can become a phygital system, that can be used to monitor and protect the structural heath of complex and extended assets. Within a mutual optimization process, whose procedure is described here, this work aims to describe how to produce a preliminary vibration monitoring system design configuration, supporting the identification of some relevant metrological parameters of the monitoring systems, in terms of sensors types, their desired technical characteristics and their preliminary positioning, in relation to the measured variable. These preliminary steps are applied to the ancient Greek temple of Hera, located in the UNESCO Paestum-Velia archaeological Park site (Capaccio municipality, Italy).
