摘要
对边坡危岩的失稳变形进行监测监控是预测滑坡等地质灾害发生的有效手段。采用先进的监测技术降低现有监控系统成本、应用低成本的MEMS传感器对边坡危岩的位移、倾斜角、水压、温湿度等信息进行实时监测、扩大监控范围是广泛开展监测预警工作的重要保证。提出了基于无线传感器网络的山体滑坡预警系统的设计方案,介绍了系统结构,详述了系统的硬软件设计、基于无线传感器网络的分层网络结构、无线路由的构建、对环境监控信息的按需采样、实时可靠传输,通过GPRS实现远程信息交互。
Monitoring of slope-instabilities and deformations is an effective means to monitor and forecast landslide.It is therefore crucial to use new technologies to reduce monitoring costs,to use low-cost MEMS sensors to measure the changes of displacement,acceleration,tilting,pressure,temperature,humidity,etc.and to enlarge applicable regions for the demands of extensive landslide warning.A designing scheme of landsliding early-warning system on wireless sensor network is proposed and system architecture is introduced.This paper describes the system structure.The design of hardware and software,hierarchical network structure,construction of wireless routing,sensor data sampling on demand and GPRS based transmission of remote data are designed.
