摘要: 对滑坡区域进行地表高精度实时三维变形监测,是实现滑坡灾害精准预警的前提。GNSS技术是目前唯一直接获取滑坡灾害实时地表三维矢量变形的手段,但GNSS应用于大范围滑坡监测存在成本高和计算能力差两大问题。本文采用物联网思维,以"云+端"的设计理念,自主研发了千元级小型化实时北斗/GNSS监测技术装备,并研制了毫米级实时监测预警云平台,成果成功应用于甘肃黑方台滑坡实时监测预警。联合成都理工大学预警系统提前40 min发出了准确预警信号,避免了人员伤亡和财产损失。安装在滑坡体上的远程视频监控首次近距离记录了滑坡灾害发生的全过程。

Abstract: Implementing the high-precision, real-time and three-dimensional deformation monitoring for the landslide area, which is the prerequisite for the accurate warning of landslide disasters. GNSS technology is currently the only way to directly obtain the three-dimensional vector deformation of landslide disaster surface, but GNSS has two problems of high-cost and low-reliability in large-scale landslide monitoring. The ideas of Internet of Things and the concept of "cloud platform plus monitoring terminal" are proposed in this article. Thus, we develop a real-time BeiDou/GNSS monitoring equipment with thousands RMB cost. The millimeter monitoring and warning cloud platform also are developed independently. This equipment successfully applied to real-time monitoring and early warning of Heifangtai landslide in Gansu Province. Cooperated with early warning system of the Chengdu University of Technology, we issued an accurate warning signal 40 minutes in advance to avoid casualties and property losses. The remote video surveillance installed on the landslide body recorded the whole process of landslide disaster for the first time.

Key words: landslide, GNSS, BeiDou, low cost, high-precision, monitoring and early warning
