摘要
介绍了泥石流的形成机理,对现阶段的泥石流监测方法进行了分析和比较,给出了基于无线传感器网络的泥石流关键因子的小尺度观测方法,阐述了传感器节点的硬件构造方法、节点部署方法和节能通信协议。传感器网络不仅为泥石流机理的深入研究提供了数据源,也为泥石流灾害预报和预警机制的建立奠定了基础,有助于降低泥石流地质灾害的损失。
In this paper,the mechanism of Debris Flow is summarized.The existing methods for Debris Flow monitoring are analyzed and evaluated.A method is presented for monitoring the key factors of Debris Flow based on wireless sensor networks（WSNs）.The construction of nodes of WSN,as well as deployment of nodes and energy efficient protocol is introduced as well.WSNs does not only provide the data source for the mechanism exploration of Debris Flow,but also can be established as an infrastructure for Debris Flow forecasting and early warning.Application of WSNs in key factors surveying is conducive to reduction of loss caused by Debris Flow.
