Visual real-time monitoring method for discrete manufacturing workshop based on digital twin

Focusing on the problems of real-time monitoring, poor control ability and opaque management in discrete manufacturing workshop, an object-oriented method was proposed to realize a real-time monitoring method for discrete manufacturing workshops based on Digital Twin (DT). DT-based visual real-time monitoring method architecture for discrete manufacturing workshop was built, and its key implementation process was clarified. Four key technologies to realize real-time monitoring based on DT were described in detail, including data modeling and transmission method based on AutomationML and OPC UA, event-driven virtual and real mapping method, workshop logic modeling method based on complex event processing, information visualization and push. Taking an aerospace product machining workshop as an application case, the effectiveness of the monitoring method was verified by combining the actual production process and the developed prototype system. © 2021, Editorial Department of CIMS.
