滑坡监测系统数据传输方式优化设计

Optimal Design of Data Transmission Mode of Landslide Monitoring System

针对极端环境下(如地震、泥石流、暴雨等),全球移动通信系统GSM通讯信号中断等原因引起的边坡监测滑坡监测预警系统数据传输中断,提出了基于我国自行研制的北斗卫星导航系统的数据传输方式优化设计。系统由野外监测点和室内监测站组成,能对滑坡体的地表裂缝位移、倾斜度、降雨量等参数进行实时监测,以达到预警滑坡地质灾害发生的目的。对数据传输方式的优化设计,主要体现在以北斗短报文的方式将监测数据上传至室内监测站,克服了原有GSM通信方式的易受天气影响、时间延迟大等不足,提高了数据传输方式的可靠性。该设计已应用于"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。

As for the GSM's data transmission interruption of slope monitoring and landslide monitoring warring system caused by factors like communication signal interruption under extreme circumstances(such as earthquake,debris flow and rainstorm),the optimal design of data transmission approach based on BDS developed by our own nation has been put forward. The system consists of both outdoor acquisition node and indoor monitoring stations that can monitor the parameters of landslide displacement and slope rainfall timely to warn landslide geological hazards. The reformative design of data transportation mainly present in the way to upload monitoring data to the indoor monitoring station via the Beidou navigation system in form of short message.In this way,the reliability of data transmission has been improved and it has overcome many shortcomings of the GSM,which has a high latency and is easy to be affected by weather. 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.
