摘要： An apparatus for communicating information over a pressurized fluid-carrying pipe connecting a plurality of serial nodes. A sounder node (i.e., transmitter) creates variable pressure patterns within the fluid-carrying pipe, which pressure patterns are identified and detected by other nodes. The patterns convey information or solicit responses from the receiving nodes. The receiving nodes reply to the pressure fluctuations by inducing reply pressure fluctuations in the fluid-carrying pipe or by communicating with the sounder node via a separate radio frequency communications system. The apparatus and method can be used as an information-carrying communications medium or a train linking methodology for a railroad train.
