摘　　要：针对我国地质灾害频发的现象,该文讲述了一种基于传感网与多网络融合技术的地质灾害监测预警系统的设计。该系统以基于Cortex-M3内核的微控制器STM32为核心,多通道信号调理电路为数据采集单元,采用电台、Zigbee和直接连线等方式组建本地监测网,将多种传感器(雨量计、地表裂缝位移计、孔隙水压力计、土壤含水率计、地下水位计等)的数据采集、处理后通过GPRS网络和北斗卫星传回服务器。实际应用显示,本系统具有功耗低、稳定好等特点,能适应野外恶劣的环境,满足监测需要。This essay,aimed at the disaster-prone phenomenon in China,gives the designs of the geological disaster moni- toring system based on the sensor netting and multi-communication network fusion technology. The system takes the micro- controller STM32 which was based on the Cotrex-M3 kernel as the core,the Multi-channel signal conditioning circuit as the data acquisition unit,and adopts Zigbee wireless network,radio station and direct wire communication network to form local area network. The system collects the data of various sensors, including（rain gauges pore water pressure, soil moisture, surface crack displacement meter,etc）data acquisition. Then it processes and sends the data back to the server via GPRS network and Beidou satellite. Practical application shows that the system has provided with the good characteristics such as low power consumption, good stability, and it also can adapt to the wild harsh environment to meet the needs of monitoring.
