Earth-rock dam monitoring system based on fiber grating sensing network

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.
