Abstract

During the use of the earth-rock dam,it will be damaged because of the long-term effect of the load,the material aging,environmental erosion and other factors.In order to effectively monitor the earth rock dam health status and identify the structural damage,and further to predict the life of earth rock dam,it is necessary to establish the earthrock dam monitoring system.In view of the hierarchical structure of the things of internet,an earth dam monitoring system is developed.It uses a transmission technology of full optical fiber and based on Fiber Bragg Grating sensing network,which uses the FBG sensor as the detecting unit.It can collect and process the important data of the earth-rock dam,like cracks and pressure.Practical application shows that the system can show the key parameter information of the condition of the earth-rock dam and play a supporting role in the projecting of earth-rock dam reinforcement and the dam understanding of the whole situation.

基于光纤光栅传感网络的土石坝监测系统

土石坝在使用过程中，由于荷载、材料老化、环境侵蚀等因素的长期作用，会造成破坏。为了有效地监测土石坝的健康状况，识别结构损伤，进而预测土石坝的寿命，有必要建立土石坝监测系统。针对物联网的层次化结构，开发了土坝监测系统。它采用全光纤传输技术，以光纤光栅传感网络为基础，以光纤光栅传感器为检测单元。它可以采集和处理土石坝裂缝、压力等重要数据。实际应用表明，该系统能较好地显示土石坝状况的关键参数信息，对土石坝加固工程的规划和坝体整体情况的了解起到辅助作用。

期刊介绍： The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months. The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
