基于无线传感网的桥隧坡健康监测预警系统

Bridge-Tunnel-Slope Health Monitoring and Early Warning System Based on Wireless Sensor Network

分析了高速公路桥梁、隧道、边坡健康状况监测预警的现状和需求,设计了一套基于无线传感网的自动监测预警系统,将孤立的桥梁、隧道、边坡安全健康监测纳入到一个统一的管理平台,使用统一的数据标准、通讯标准、软件平台,大大减少了重复投资,降低了维护费用和难度,提高了管理效率。同时,由于使用无线传感网作为现场监测设备的通讯系统,大大减少了通讯线缆的使用,降低了工程难度和投资,提高了系统的灵活性、易扩展性和易维护性。

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.
