黄河老田庵控导工程丁坝变形监测系统的设计

Design of Safety Monitoring System for Spur Dikes of Laotianan Project in Yellow River

基于光纤光栅传感技术,设计了具有通用性的黄河老田庵控导工程丁坝安全监测系统的硬件及软件,并在老田庵24号坝进行安装,通过对监测数据的筛选、分类以及统计,建立起"正常,非正常,险情"三级预警系统,采用监测历史数据的标准差固定倍数作为预警的参考值,以达到及时预警的目的,并可实现监测历史数据查询等功能。

Safety monitoring of spur dikes of Yellow River is one of the most important methods to find the abnormality and the potential failure of spur dikes.This paper made a special design of hardware and software of versatile security monitoring system for spur dikes of Laotianan Project in Yellow River based on the Fiber Bragg Grating（FBG） sensing technology..By using data filtering,classification as well as statistical analysis,we established a safety monitoring system with three levels of security status：normal,abnormal and dangerous.Based on the theoretical calculations of data,the real-time monitoring and historical view can be achieved.
