Research on Real-Time Crack Monitoring at Early Warning System for Rockfill Dams Based on the Internet of Things

Rockfill dams are critical infrastructures in water conservancy projects, at the development of structures poses serious threats to dam safety in regional stability. Traditional monitoring methods limited by low efficiency in a lack of intelligent analysis. To address that issues, that proposes a realtime crack monitoring in early warning system for rockfill dams based on the Internet of Things (IoT). The system integrates wireless sensor networks in cloud-based platforms to achieve continuous in remote monitoring of crack width in propagation trends. Data collected from sensors are transmitted in real-time to a central processing unit intelligent algorithms analyze structural behavior in trigger early warnings when critical thresholds are reached. The system also supports visualization in mobile access, allowing timely decision-making by engineers in management personnel. Field experiments demonstrate that the system enhances monitoring coverage, improves early warning responsiveness in reduces operational risks. That provides a practical in intelligent solution for improving dam safety management in contributes to the modernization of infrastructure monitoring using IoT technologies.
