摘　　要：为实现地质灾害监测的智能化、实时化,提高监测手段的准确性和适用性,同时降低监测成本,基于MPU-6050型MEMS加速度传感器和CC2530型ZigBee无线通信处理器,构建地质灾害监测预警系统,可实现对位移、倾角、温湿度多种参数的实时动态智能化监测,监测误差分别仅为1.5%、1.4%和2.22%。为了达到较高的数据传输可靠性和准确性,ZigBee节点距离宜控制在50 m以内,系统的平均丢包率仅为0.83%,平均信号强度达到35.5 dBm;工作人员通过设置各级预警阈值和调取历史数据,可对地质灾害进行实时精准综合研判,及时制定预防和应急预案,防止地质灾害的发生或者造成重大的人员财产损失。In order to achieve intelligent and real-time geological hazard monitoring,improve the accuracy and applicability of monitoring means,and reduce monitoring costs,a geological hazard monitoring and early warning system is built based on MPU-6050 MEMS acceleration sensor and CC2530 ZigBee wireless communication processor,which can realize real-time dynamic intelligent monitoring of multiple parameters such as displacement,inclination,temperature and humidity.The monitoring errors are only 1.5%,1.4%and 2.22%.In order to achieve high data transmission reliability and accuracy,ZigBee node distance should be controlled within 50 m,the average packet loss rate of the system is only 0.83%,and the average signal strength reaches 35.5 dBm.By setting early warning thresholds at all levels and accessing historical data,staff can conduct real-time,accurate and comprehensive research and judgment on geological disasters,and timely formulate prevention and emergency plans to prevent geological disasters from occurring or causing significant personnel and property losses.
