青海省数字地震数据准实时传输研究

STUDY ON DIGITAL SEISMIC DATA QUASI-INSTANTANEOUS TRANSMISSION IN QINGHAI PROVINCE

通过对青海省"九五"新、改建数字地震台地震数据传输方式的研究,用X 25组建数字地震台网广域网,可方便地实现数字地震数据的准实时传输,其组建简单,台站终端设备接入方便,运行成本低;同时,数字地震台网广域网也可用DDN、RF组建,使"九五"已建台站和"十五"待建台站数据传输良好地衔接。

The digital seismic wide net is set up by X.25 on the base of building or rebuilding the digital seismic data transmission in 'the ninth five-year project'in Qinghai province.And this wide net is set up easier and the cost is lower ,and it can make quasi-instantaneous transmisson.It can be set up by DDN and RF,too,and linked up the seismic data transmission in 'the ninth five-year project' and'the tenth five-year project'.
