Design of a centralized intelligent control system architecture for NC machining production lines

To make the machining equipment on a production line more smart and connected, a centralized intelligent control system architecture is proposed. The equipment control systems are integrated into a clustered data center with big data processing ability. Industrial Real-time Ethernet is applied for machine controlling and process data acquisition. The massive process data are stored and analyzed with the big data processing platform. With the application of machine learning tools, intelligent control models and algorithms could be trained by making use of the large-scale process data. And the processing technic could be improved by optimizing the process parameters. All the process data and parameters in the data center are shared by the control systems of different equipment, each machine could adjust its technological parameters adaptively according to the output information of previous working procedure. The proposed system architecture could promote the flexibility and the level of automation of production lines in the era of big data.
