Composite machine tool digital twinning monitoring system

Abstract

The invention discloses a composite machine tool digital twinning monitoring system, which relates to the technical field of digital twinning. The composite machine tool digital twinning monitoring system creates a digital twinning monitoring system through using a machine tool information module, realizes multi-platform, multi-data and multi-interface communication based on an OPCUA transmissioninterface, and constructs a man-machine interaction module; a multi-field data acquisition module acquires multi-source heterogeneous data in real time by adopting different types of sensors, processes the acquired data based on an information fusion technology to form twin data, and forwards the twin data to a modeling calculation module; the modeling calculation module is used for forming a digital twinning body of a compound machine tool through driving of the twin data in combination with rules such as constraint, prediction and decision; and a personalized decision module monitors and manages entity machine tool equipment in real time by reconstructing and optimizing a machine tool monitoring twinning model in real time. According to the composite machine tool digital twinning monitoring system, the monitoring process of the operation of the compound machine tool is simplified, the monitoring precision of the machine tool system is improved, and the active predictive maintenance of the operation of the compound machine tool is realized.

Description

technical field [0001] The invention belongs to the technical field of digital twins, and in particular relates to a digital twin monitoring system for a compound machine tool. Background technique [0002] The essential concept of a digital twin is a quasi-real-time digital mirror of a physical entity or process. Compared with traditional life cycle management and simulation technology, digital twin has the characteristics of two-way, continuous and open. Through virtual and real interactive feedback, data fusion analysis, decision-making iterative optimization and other means, new capabilities can be added to physical entities. For the field of manufacturing, digital twins can be defined as "a dynamic model that digitally describes manufacturing elements such as people, products, equipment, and processes, and is updated and optimized synchronously with changes in object development status, working conditions, and product geometry. ”, reflecting the whole life cycle proces...
