Telemetry and Telecontrol Applications in Oil amp; Gas Extraction Process

摘要

The presentation relates to the computer based telemetry and telecontrol system being engineered by RCPO for application in oil and gas extraction in Bombay offshore oil fields of ONGC. The system consists of a number of complexes, each comprising a central gathering platform having a PDP-11 computer based telemetry master with remote terminal units (RTUs) in outlying unmanned platforms around the central platform. The RTUs are solar powered and are linked to the master via FDM/FM/UHF radio links. Some RTUs are linked directly by a 4 wire communication cable. The central locations comprising the computer are called nodes.
