Tunnel Health-monitoring System Based on Low-power Wireless Sensor Networks

针对隧道健康监测系统中有线的工作方式在复杂工程环境下适应性差的问题,提出了一种基于监测传感器无线通信组网与低功耗供电的隧道健康监测系统。系统结合监测传感器采集频率与工作环境的特点,搭建了隧道监测传感器无线LORA通信局域网,制定了监测中心节点与终端节点的通信协议,设计了监测终端节点低功耗供电策略,满足监测终端电池供电下长期数据采集的需求。最后通过试验证明了该方法的有效性。

Aiming at the problem of poor adaptability of Communication via cable in tunnel health-monitoring system in complex environment,a tunnel health monitoring system based on low-power wireless sensor network is proposed. The system combines the characteristics of sensor acquisition frequency and working environment,builds a wireless communication LAN for tunnel monitoring sensor,and establishes the communication protocol between the monitoring center node and the terminal node. The low-power supply strategy for monitoring the terminal node is designed and realizes long-term data acquisition under the battery power supply. The experiment proves the validity of the method.
