Research on Seismic Data Compression and Error Correction System

This paper introduces a seismic data compression and error correction system suitable for digital seismic stations and networks. The transmitter of the system performs 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 performs inverse processing to realize the error correction function and outputs the seismic data in 24-digit format to the computer. This paper describes the working principle, hardware structure and main functions of the instrument.
