BridgeSync: A Digital Twin Framework for Secure and Intelligent Smart Bridge Monitoring

초록

This paper introduces BridgeSync, a novel digital twin framework for secure and resilient real-time bridge monitoring. BridgeSync leverages blockchain technology and edge computing to overcome the limitations of traditional bridge monitoring systems, such as security risks and high latency. The framework integrates PureEdge, an edge computing approach, to enable offline data caching and synchronization, and it integrates with PureChain, a cost-efficient blockchain network, for secure and tamper-proof sensor data storage. Additionally, BridgeSync uses 3D immersive visualization to provide an interactive and intuitive platform to monitor bridge conditions. The system was validated by modeling three bridges as digital twins and comparing them to their physical counterparts, confirming accurate structural replication. Further evaluation demonstrated BridgeSync's real-time monitoring and interactive visualization capabilities through sensor integration tests.
