Implement of Data Communication in Smart Factory with OPC-UA Architecture

In response to the increasing demand for information collection and data communication in automated control devices in an intelligent manufacturing factory, this paper proposes an OPC UA-based intelligent communication method for factory automation and discusses its communication principles and network architecture in detail. This paper also explores the integration of OPC UA with devices such as industrial robot ROS systems and sensor-embedded systems and introduces a Python-based data communication program design method. Ultimately, this paper successfully develops an MES robot monitoring module based on the OPC UA architecture and conducts a case study. The practical application results show that OPC UA-based data communication technology has high versatility and compatibility, and can effectively achieve data integration and unified management of intelligent workshop equipment information. This technology has broad application prospects and promotional value, providing a useful reference for the information construction of intelligent manufacturing factories.
