INTELLIGENTIZED NETWORK SEISMIC MONITORING AND REALTIME DATA PROCESSING SYSTEM

As we know, the SSDP mutual analysis software for seismic data processing has been widely used in many digital seismic stations in China. However, some inefficient functions in the software have limited its applications, namely: (1)Seism containing lg seismic phase cannot be located. (2)Magnitude m_B and m_b cannot be calculated. (3)Seismic catalogue cannot be generated automatically. (4)It depends on other software (for example SSB) to do the seismic instant report and the seismic data cannot be shared. (5)Precision in calculating local seismic parameters can't be guaranteed. (6)Epicenter can't be showed in the map. As a solution to these problems, we developed a new intelligentized network system based on VB (Visual Basic) for seismic monitoring and data processing. Compared with SSDP system, we added some new functions to the system, such as real-time monitoring of working status of seismic equipment, seismic parameters calculation and instant seismic reporting by itself. The implements also include searching of seismic events, automatic editing of seismic catalogs, analyzing of seismic phase and transmitting data. Our software has been used effectively in the Luoyang Station of Henan province over one year. It is able to deal with all daily works and alleviate the workload in digital seismic station, and it is helpful in improving the quality of seismic monitoring. The advantage of digital seismograph has been brought into full play.
