| Abstract: | Aim at solving online hidden deformation monitoring problems for the embankment dams with long distance and large area, a monitoring system using distributed stimulated Brillouin scattering optical fiber sensing is proposed. Data acquisition principle of the distributed optical fiber sensing instrument is briefly introduced and Data Flow Diagrams (DFDs) is analyzed. Take the Yellow River embankment dam as an example of being monitored. The monitoring system based on DiTeSt-STA202, which is a distributed opt... |
