The technique of micro seismic monitoring data compression
-
Abstract
The substantial microseismic monitoring data bring many difficulties to the long distance wireless real-time transmission of data and,what is more,take up a lot of disk space.In this paper,using adaptive threshold STA/LTA algorithm,the authors select appro-priate characteristic function and automatically,quickly and accurately identify effective micro-seismic signal from the large quantities of monitoring data.Then,the method on the paper accurately determines the start and end time of the effective micro-seismic signal com-plete waveform,and removes large quantities of redundant data by completely intercepting valid signal,so that the original data are re-duced to 20%.Finally,the monitoring data compression ratio attains 10 ∶ 1 by using STEIM2 algorithm compress data intercepted.
