Natural Disaster Risk Monitoring for Immovable Cultural Relics Based on Digital Twin.

Natural disaster risk monitoring is an important task for disaster prevention and reduction. In the case of immovable cultural relics, however, the feedback mechanism, risk factors, monitoring logic, and monitoring indicators of natural disaster risk monitoring are complex. How to achieve intelligent perception and monitoring of natural disaster risk for immovable cultural relics has always been a focus and a challenge for researchers. Based on the analysis of the concepts and issues related to the natural disaster risk of immovable cultural relics, this paper proposes a framework for natural disaster risk monitoring for immovable cultural relics based on the digital twin. This framework focuses on risk monitoring, including the physical entities of natural disaster risk for immovable cultural relics, monitoring indicators, and virtual entity construction. A platform for monitoring the natural disaster risk of immovable cultural relics is proposed. Using the Puzhou Ancient City Site as a test bed, the proposed concept can be used for monitoring the natural disaster risk of immovable cultural relics at different scales. [ABSTRACT FROM AUTHOR]
