基于物联网与三维可视化技术的大坝安全管理平台及其实现

针对大坝安全管理信息获取不够全面、数据可视不充分的问题,利用物联网技术构建了覆盖大坝空中、地表、内部、水下等全空间一体化的信息感知体系,研究了三维可视化技术在海量地形调度、大坝与地形镶嵌、安全信息在三维空间的表达等技术难点,设计了大坝安全管理平台,实现了大坝安全信息在真实地理空间的快速、高效、直观展示,为管理者提供了快速获取大坝安全性态的手段,提高了大坝安全管理水平,以三维地理信息可视技术构建流域空间参考,将不同的大坝进行统一管理,解决信息孤岛问题,推进数字、智慧化建设工作,补齐了智慧大坝安全管理在信息化领域的短板。

Research and Implementation of Dam Safety Management Based onInternet of Things and Three-dimensional Visual Technology

The management information of dam safety is not comprehensive enough and the data is not fully visible. In view of this, we employed the Internet of Things technology to construct an information perception system covering the dam’s air, ground surface, interior and underwater spaces. Faced with the technical difficulties of massive terrain scheduling, dam and terrain inlay, and the expression of safety information in three-dimensional space, we designed a dam safety management platform integrating the Internet of Things technology and 3D visualization technology to display dam safety information in real geography. The rapid, efficient and intuitive display of space provides managers with a means to quickly obtain dam safety status, improve the dam safety management level, and overcome the shortcomings of intelligent dam safety management in the field of information technology.
