Oil field process control system

摘要

An oil field process control system including a field versatile control gateway component that interfaces with a plurality of field devices using a broad range of hardwired and wireless protocols, offering in-the-field monitoring and control of each of the field devices and communicates with a remote central control room, exchanging data between the control room and the field using a multiplexed protocol that offers high data speeds and bandwidth, enabling a significant reduction of the amount of wiring, and conduits and other infrastructure expenses that would otherwise be incurred for such a highly reliable communications system.

主权项

1. A field versatile control gateway (FVCG) operable to communicate with control equipment within a remote CCR and/or PIB and adapted to interface with a plurality of field devices that constitute a process control system, the FVCG comprising a microprocessor, memory, routing database, routing module, protocol translator, wireless interface card and antenna;
wherein the FVCG provides for control-in-the-field capabilities, and wherein the FVCG communicates with field devices using one or more protocols selected from the group consisting of 4-20 mA, Fieldbus Foundation H1, on/off interface, wireless, serial, and EI, and wherein the FVCG provides for multiplexed communication of data between the FVCGs and a central control location via one or more of a hardwired HSL protocol, a wireless connection, or a hardwired HSL protocol and wireless connection, and wherein the routing database and routing module routes data between the field devices and the FVCG microprocessor and between the FVCG microprocessor and a remote CCR and/or PIB, wherein the protocol translator converts field device data from 4-20 mA, Fieldbus Foundation H1, serial, EI and on/off interface protocols into HSL protocol for communication with the remote CCR and/or PIB wherein the FVCG monitors smart field device self-diagnostics and applies the monitored diagnostics to the FVCG control-in-the-field capabilities, and wherein the control equipment within the CCR and/or PIB monitors the FVCG status and determines whether to allow the FVCG to continue control-in-the-field, or whether to transfer control functions back to the control equipment within the CCR and/or PIB.
