边坡失稳和变形监测是滑坡监测和预报的有效手段。因此，使用新技术来降低监测成本，使用低成本的MEMS传感器来测量位移，加速度，倾斜，压力，温度，湿度等的变化至关重要。扩大滑坡预警的适用范围。提出了一种基于无线传感器网络的滑坡预警系统设计方案，并介绍了系统结构。本文描述了系统的结构。设计了硬件和软件的设计、分层网络结构、无线路由的构建、传感器数据的按需采样和基于GPRS的远程数据传输。
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.
