STUDY ON DIGITAL SEISMIC DATA QUASI-INSTANTANEOUS TRANSMISSION IN QINGHAI PROVINCE
WU Zhe · Plateau Earthquake Research · 2003
The digital seismic wide net is set up by X.25 on base of building or rebuilding digital seismic data transmission in the ninth five-year projectin Qinghai province.And this wide net is set up easier and cost is lower ,and it can make quasi-instantaneous transmisson.It can be set up by DDN and RF,too,and linked up seismic data transmission in the ninth five-year project andthe tenth five-year project.
