摘要
介绍了超短波、公众交换电话网(PSTN)、国际海事卫星C类业务(INMARSAT-C)、全线通卫星(OmniTRACS)这4种通信信道在三峡水情自动测报系统中的应用,详细论述了传输中的关键问题。
This paper introduces the applications of very high frequency （VHF）, public switched telephone network （PSTN）, the C-operation for maritime satellite （INMARSAT-C） and OmniTRACS communication channels to the Three Gorges automatic hydrological data acquisition and transmission system, and discusses the key problems in data transmission in detail.
