外观形变监测是水库大坝安全监测系统的重要组成部分,是水库日常管理工作中的一项重要内容。文章以高精度差分全球定位系统(GPS)位置测量为基础,GPS多天线阵列接收技术为核心,设计了一种饮用水源水库大坝外观形变自动监测系统,并探讨了该系统的设计、组成、工作原理等。实践测试结果表明该系统满足大坝外观形变监测要求。
Visual deformation monitoring is an important part of reservoir dam safety monitoring system and is an important part of reservoir daily management. Based on the high accuracy differential GPS (Global Positioning System) position measurement and the GPS multi-antenna array receiving technology, this paper designs an automatic monitoring system for appearance deformation of drinking water source reservoir dam and discusses the design and composition of the system , Working principle and so on. The practical test results show that the system meets the monitoring requirements of dam appearance deformation.
