Synopsis:
The oil and gas industry includes processes for exploration, extraction, refining, transporting, and marketing petroleum products. The largest volume products of the industry are fuel, oil and gasoline (petrol). Petroleum is also the raw material for many chemical products, including pharmaceuticals, solvents, fertilizers, pesticides, and plastics. As the demand for fossil fuels continues to grow, oil and gas companies will have to develop new technologies and improve operations in order to increase productivity and expand on their current abilities.
The local monitor of oil field consists of data acquisition module, Zigbee communication module, Remote Terminal Unit (RTU), field data acquisition computer and local central server. In SCADA systems, an RTU is a device installed at a remote location that collects data, codes the data into a format that is transmittable and transmits the data back to a central station, or master. An RTU also collects information from the master device and implements processes that are directed by the master. RTUs are equipped with input channels for sensing or metering, output channels for control, indication or alarms and a communications port. The transceiver of monitoring center receives the signals from the air delivered by oil field RTU, and then amplifies and demodulates RF signals, restores the signals into data transfer signals and sends them to central industrial control computer to calculate, real-time monitors oil well status. When something appears abnormal, the central Industrial PC sends out commands to the RTU of oil field to stop motor and wait for maintenance. The whole system runs automatically and can be monitored without human interference
