Research on Seismic Data Compression and Error Correction System

This paper introduces a seismic data compression and error correction system suitable thy digital seismic stations and networks. The transmitter attic system pertorms intra-frame compression and inter-frame redundancy on seismic data, and sends the processed data Return to the seismic monitoring center through wired or wireless channels. After receiving the data, the real-time compression and error correction equipment of seismic data in the seismic monitoring center perfomis inverse processing to realize the error collection function and outputs the seismic data in 24 -digit fonnat to the computer. This paper describes the working principL hardwire structure and main functions of the instmment.
