Design & Implementation of the Pulse Calibration Processing System for Seismic Network

Abstract

Pulse calibration is an important work for the regional seismic network center. With the scaled amplitude and period from pulse calibration, engineers can understand the running state of the seismographs. A variation above %5 usually means a fault and there should be something wrong with the sensors or digitizers. The various faults are important references for station maintenance, but some of them are ever ignored by the engineers due to the lack of specialized storage and management procedures. In order to make better use of the faulting records, we have developed software SPMIS with VC++ for the regional seismic network center. With the software, users can not only achieve the routine work of pulse calibration measurement, but also the fault classify and storage. The application of SPMIS will be helpful to improve the efficiency of the operation maintenance work for the seismic network center.
