Problems solved by technology

[0002] Conventional oil drilling rig control includes gas circuit control system, hydraulic control system, and electrical control system, which are realized through manual operation of the console installed in the driller's room. Each control mechanism is independent and decentralized, so that the driller's console has a large number of components. , These components are connected through a large number of pipe fittings and connectors. Failure of one component will often cause abnormal operation of the entire equipment, and even cause equipment accidents. Moreover, the installation and connection of discrete components is time-consuming and laborious, and the pipelines are messy and criss-crossed. , Inconvenient disassembly and assembly, there are many problems such as high failure rate in operation, difficult debugging, cumbersome operations for drillers, and easy misconnection and misoperation
Of course, traditional control cannot realize remote monitoring

Embodiment Construction

[0043] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0044] Such as figure 1 As shown, the automatic control system of the oil drilling rig in this embodiment includes a master station and a plurality of slave stations.

[0045] The PLC controller and its redundant PLC controller installed in the integrated cabinet are the main station of the entire control system. Its analog input module collects the volume of No. 1 to No. 8 mud pools, the DC current of No. 1 to No. 4 rectifier cabinets and the temperature of the resistance room. Its digital input module collects the running status feedback signals and alarm signals of each actuator, where the signals include the running status of 1~5# generator sets, brake unit prohibition, warning silence, 1~3# mud pump fan running status, 1 ~3# mud pump air pressure circuit status, 1~3# mud pump filling pump running status, 1~3# mud pump spray pump running status, 1~...
