Abstract

In this study we present a method to sort measured-data and process signal for special hydrodynamic monitoring system based on distributed optical fiber sensors. The procedure consists of defining the attribute of the data, data processing and information matching. The data of for-processing-part are processed regularly, which directly provides results for the user from the monitoring system. These results go into the next step to add environmental parameters, which includes weather, special events and season information. Information fusion and matching operation of the result and environment information enhances the accuracy of hidden hazard early warning.
