GAS TRANSPORTATION SYSTEM AND METHOD OF OPERATING GAS TRANSPORTATION SYSTEM Russian patent published in 2016 - IPC F17D5/00 H04B13/00 

FIELD: transportation.

SUBSTANCE: group of inventions relates to pipeline transport. To prevent corrosion in the pipeline cathodic protection system is used, which comprises a plurality of ground rods in the ground, which are each electrically connected with the ground and are electrically connected to being in connection with the soil pipe. To provide a little difficulty with respect to the pipeline system communications infrastructure, communication between communication devices through the pipeline itself. Communication devices comprise a sensor units and input nodes in a central processing unit. Arranged along the pipeline sensor units are used to measure signals and are equipped with energy of cathodic protection system. As a result, there is no need in separate power supply system. For power supply completely from cathodic protection system, each autonomous sensor unit is equipped with such components which enable communication with the help of less complicated methods of modulation.

EFFECT: due to treatment of soil concussions signals and their classification, alarm messages in the input nodes are transmitted only when recognising critical events.
