三峡数字遥测地震台网多制式复分接设备应用简介

Introduction on the multi-system equipment of compound and de-compound used in Sanxia Digital Tele-metering Seismic Network

介绍了应用于三峡数字遥测地震台网黄牛岩中继站至八河口记录中心的多制式高次群复分接设备。该设备将 30路多种不同制式不同速率的地震波数据汇集成一路高速数据流 ,通过数字微波传送。该设备采用“异步采样”技术成功地解决了多种数据流的汇集和分流问题。

The multi-system compound and de-compound equipment used in Huangniuyan Relay Station in Digital Tele-metering Seismic Network of Sanxia is described here.The equipment convergences 30 channels seismic waves data into one channel signal,in which the frequencies of data are different and multi system,and transmits all signals transmitted through the digital micro wave.The technique of transmission in this equipment solves a lot of converging and diverging problems of data streams.
