Abstract

The invention discloses a drilling machine integrated loop network communication control system based on a PLC. The drilling machine integrated loop network communication control system based on the PLC comprises a master operational console, wherein the master operational console is respectively connected with a master operational console PLC station and a client end, the client end is connected with a network NET2 and a network NET3 simultaneously, the network NET3 is connected with a CCTV controller, the network NET2 is connected with an auxiliary server, a database server and a master server, the network NET3 is connected with a network NET5, the network NET5 is connected with a master long-distance monitoring station, the network NET2 is connected with a network NET4, the network NET4 is connected with a master long-distance monitoring station, the master operational console PLC station and the master server are further connected with a network NET1, and the network NET1 is respectively and correspondingly connected with a first PLC control station and a 400H redundancy control station. The drilling machine integrated loop network communication control system based on the PLC achieves automation, intellectualization and networking of the control system, and is good in real-time performance and stable and reliable in communication service.

Description

technical field [0001] The invention belongs to the technical field of automatic control, and relates to a PLC-based drill rig integrated ring network communication control system. Background technique [0002] With the advancement of science and technology, the control system of oil drilling rig equipment is more in pursuit of automation, intelligence, and networking, which liberates people from tedious and hard work, completes related operations with control machinery and equipment, and reduces staffing, especially in some In dangerous situations, through the application of automatic, intelligent and networked control system, the control equipment can be operated remotely, so that the operator is far away from the dangerous area, and truly "people-oriented". [0003] At present, oil rig equipment requires uninterrupted operation, and downtime will cause heavy economic losses. At this time, higher requirements are put forward for the stability and reliability of the control...
