Abstract: To improve intelligent control level of oil and gas fields and intelligent level of production management process, the latest Siemens technology is introduced from Germany to independently develop station integrated monitoring and control cabinet by means of integrated creation. The cabinet has the functions of automatic monitoring, close-loop control, safety interlock and remote control for all production processes of oil and gas metering stations and gathering stations at oil and gas fields. It can be used for real-time acquisition of key production parameters needed in the processes of stations, close-loop control and safety interlock of electric and pneumatic actuators, and automatic shutdown of the whole station under emergency. The cabinet can provide redundancy function according to users’ requirements. It can also provide multiple communications interfaces and communications protocols to inter-exchange and share data with host computer. The cabinet is safe and reliable in operation and its performance reaches China’s advanced level.
