Comparative Analysis of Data Transmission Quality of Seismic Station Based on Different Communication Modes

摘要

In this paper, the VPN tunnels are selected based on wireless 4G network card or fiber broadband, MSTP digital optical fiber and other communication methods. The paper uses the seismic station in Hunan Province to set up seismic observation instrument, at the same time, compares the observation data of the same location which obtained by the above communication modes, through the analysis of data transmission test results. The best mode of communication for the new seismic stations is selected, which provides a reference for communication.
