| Abstract: | We comprehensively analyze the characteristics of the sensor in dam safety monitoring system. In the combination of the development of new type of sensor system of microseismic monitoring etc. and the analysis of the system information flow, the fundamental principle of expansion realization of information sources under 5 patterns of sensor, simulation signal, digital transducer, digital signal and database is revealed. The characteristics of the above-mentioned information sources expansion are analyzed through practical case and E-R graph and the solution of integrating the microseismic monitoring into dam safety monitoring via database is put forward. |
