Real-Time Monitoring System of Microseismic Signal based on Virtual Instrument and Wavelet Analysis

ABSTRACT

Seismic acquisition and monitoring system can collect, store, analyze and dispose the rock burst seismic waves or the vibration of other objects. This paper utilizes single chip computer technology, virtual instrument technology, sensor technology, database management technology, wavelet analysis technology, combining the real condition of the mine microseismic signal to establish a set of mine microseismic signal real time monitoring and warning system. Finish the seismic signals data collection by the single chip microcomputer and its periphery circuit design, meanwhile use the powerful graphical programming capabilities and flexible diversify data processing functions of the LabVIEW software, combining with advanced digital signal processing technology such as wavelet transform to complete seismic signal acquisition and filtering processing, records and analysis., monitoring and early warning functions which offers evidence for the safety monitoring of underground mine and has a good application prospect.
