Bridge-Tunnel-Slope Health Monitoring and Early Warning System Based on Wireless Sensor Network
This paper analyzes the current situation and demands of the monitoring and early warning for the health status of expressway bridges,tunnels,and slopes,and proposes an automatic monitoring and early warning system based on the wireless sensor network.The system integrates the safety and health monitoring of isolated bridges,tunnels,and slopes into a unified management platform with consistent data standards,communication protocols,and software,greatly reducing repeated investment and maintenance costs and difficulties,and improving management efficiency.Using the wireless sensor network as the communication system for field monitoring devices can significantly decrease the need for communication cables,reduce engineering difficulties and investments,and enhance the flexibility,scalability,and maintenance of the system.
