摘要
针对我国偏远地区滑坡监测通讯盲区问题,介绍了一种基于北斗通信的远程滑坡监测系统。系统由室外采集节点、室内监测中心组成。室外采集节点采集滑坡体地表裂缝位移、地表倾斜角、局地降雨量等信息,通过北斗通信终端以短报文的方式将信息传输至监测中心。室内监测中心对监测数据进行解码、存储、显示,并对灾情进行声光报警,同时可远程修改室外采集节点的采集频率。系统应用于"贵州省地质灾害监测预警与决策支持平台"项目,各项性能指标满足要求。
For some remote areas where was poor communication in landslide monitoring system in China,this paper introduce a remote landslide monitoring system based on Beidou communication. The system consists of outdoor acquisition node,indoor monitoring center. The displacement of landslide surface cracks,surface tilt angle,local rainfall and other information were obtained by outdoor acquisition node. And the information can be sent to monitoring center via the Beidou satellite communications in the form of short message. What＇s more,landslide information can be decoding,stored and displayed for early warning with the help of indoor monitoring center. The collection frequency of outdoor acquisition node also can be modified remotely. The system has been applied to the project of ＂Guizhou geological disaster monitoring and decision supporting platform＂ and it showed all performance indicators meet the requirements.
