SYSTEM FOR REMOTE MONITORING OF UNDERGROUND PIPELINES STATE Russian patent published in 2019 - IPC G08C17/02 F17D5/02 

FIELD: remote monitoring means.

SUBSTANCE: invention relates to means of remote monitoring of underground steel pipelines, as well as installed on it equipment and adjacent areas. Technical result is achieved by a system for remote monitoring of underground pipelines, comprising remote monitoring sensors with analogue and digital outputs, battery, self-contained power supply module, a communication channel which transmits remote monitoring data to the control room of the telemetry system, a measurement module comprising analogue-to-digital converters, the inputs of which are connected to the outputs of the remote monitoring sensors with analogue outputs, two matching modules, two transmission / reception modules, voltage amplifier, input contacts of which are connected to steel pipeline by means of control conductor, and grounding contacts are connected to grounding circuit, and accumulator with capacity of not less than 1 Ah, input contacts of which are connected to output contacts of voltage amplifier to provide possibility of accumulator charging from potential difference between steel pipeline and grounding circuit.

EFFECT: technical result consists in simplification of system and expansion of its application area with simultaneous increase of efficiency and reliability.
