Embodiment Construction

[0040] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0041] see figure 1 , the offshore oil drilling rig integrated network redundancy monitoring system of the present invention includes a network structure of "3 networks and 4 layers": "3 networks" are real-time Ethernet, real-time Ethernet, and field bus from top to bottom; "4 layers" from top to bottom From top to bottom are the management layer, monitoring layer, control layer and field device layer. The management layer can realize remote monitoring, the monitoring layer can realize centralized monitoring, and the control layer and field device layer can realize local control. The monitoring layer and the management layer are connected through a dual redundant Ethernet switch; the control layer and the monitoring layer are connected through a du...

Abstract

The invention discloses a marine petroleum drilling machine integrated network redundancy monitoring system which comprises a 'three-network four-layer' network structure. Three control consoles are connected with a fault-tolerant server and respectively connected with PLC corresponding to three control consoles. A fault-tolerant database server, a central control room IPC, a captain room IPC, a manager room IPC and an engineer IPC are connected with networks NET1 and NET2, the captain room IPC, the manager room IPC, the engineer IPC, a fault-tolerant data server and a fault-tolerant server are connected with networks NET3 and NET4, the fault-tolerant server and the PLC corresponding to three control consoles are connected with networks NET5 and NET6, and the fault-tolerant data server, the PLC corresponding to three control consoles and multiple locally controlled PLC substations are connected with networks NET7 and NET8. The marine petroleum drilling machine integrated network redundancy monitoring system achieves control system networking, is good in real-timeliness and high in reliability and usability, improves the well drilling operation efficiency, convenient to operate, control, expand, remove and maintain and reduces economic loss caused by accidental shutdown.

Description

technical field [0001] The invention belongs to the field of exploration and development of offshore oil and gas fields, and relates to an integrated network redundancy monitoring system for offshore oil drilling rigs. Background technique [0002] With the development of offshore oil and gas exploration and development technology and offshore drilling equipment, the number of drilling equipment controlled in the driller's room is increasing. At present, the power system, top drive, mud system, drill string automatic processing system, riser processing system, and heave compensation system of offshore drilling rigs are all self-contained systems, and there are independent monitoring platforms in the driller's room, resulting in a large monitoring system structure , Complicated control methods, inconvenient operation and maintenance, and difficult expansion. [0003] Compared with land drilling, offshore drilling has limited space, complex drilling process, harsh environment...
