Research and application of RN254 roughneck electrical control system based on Profinet and S7-1200 PLC
RN254 Roughneck is an independently developed wellhead automated unscrewing equipment by the Exploration Technology Institute.It can safely,quickly,and smoothly connect and detach drilling tools within a range of 3.5"to 10".Based on the analysis of the integrated application and functional requirements of general drilling platform automation equipment,the RN254 roughneck electronic control system was designed with the design concept of modularization and integration of platform equipment,combined with the operating conditions,mechanical structure,and hydraulic system of the RN254 roughneck.The system uses S7-1200 PLC as the control core and Profinet as the communication method,integrating all components of the roughneck in an orderly manner,achieving one key automatic control of single step action or multiple action sequence combinations.Through actual field production tests and joint debugging in the factory,the RN254 roughneck has performed well in all actions,with stable and orderly control of the main engine,verifying the feasibility and reliability of the electrical control system,improving the automation level and safety of drilling operations,and providing reference for the development of intelligent drilling equipment in the future.
