成都市遥测地震台网通讯方式现状与思考

Introduction to the communication method of the Telemetered Seismic Network of Chengdu City

随着各种数据传输技术的不断成熟和发展,越来越多的数据传输方式在地震监测中得到了广泛应用。本文简要介绍了在地震监测台网中得到实际应用的几种数据传输方式的技术特点和组网方式。同时,将超短波传输、CDMA传输、DDN传输在成都市遥测地震台网中的实际运行情况及传输性能进行比较。

With the development of all kinds of data communications, more and more transmission methods are used in the earthquake monitoring. Several of data transmission methods, their characters and combined methods are briefly introduced in this paper. At the same time, the super - short - wave, CDMA and DDN transmission techniques used in the Telemetered Seismic Network of Chengdu City are compared with each other.
