Abstract

The invention discloses a dynamic linkage control method for an autonomous production process of an intelligent workshop based on a digital twin, including: (1) constructing a digital twin model of an entity in an intelligent workshop in an information space, and establishing a virtual-real mapping relationship between the entity and the model; (2) Establish a two-way data transmission channel to realize virtual-real linkage; (3) Collect real-time status data of manufacturing resources, upload it to the digital twin model and update it; (4) Conduct real-time simulation of the operating status of the intelligent workshop, and call algorithms to predict machine tool tasks Arranging the optimal solution of the sequence and the number of the machine tool for executing the next process; (5) Analyzing the optimal solution, and sending it to each manufacturing resource entity in the intelligent workshop through a two-way data transmission channel in the form of production instructions; (6) Looping Steps (3) to (5) until all processes of the workpiece are processed. Through synchronous linkage, the dynamic linkage control of the autonomous production process of the intelligent workshop is realized.

Description

technical field [0001] The invention relates to the field of intelligent manufacturing, in particular to a dynamic linkage control method for an autonomous production process of an intelligent workshop based on a digital twin. Background technique [0002] Intelligent manufacturing has become a research hotspot at home and abroad. Strategic plans such as German Industry 4.0, American Industrial Internet, and Made in China 2025 all list intelligent manufacturing as an important theme. The implementation of intelligent manufacturing not only depends on the development of advanced manufacturing technology, but also depends on the application of emerging information technology. In an intelligent manufacturing environment, enterprise manufacturing workshops should have good production flexibility, autonomy, and production process control capabilities to meet individual customer needs. [0003] Emerging information technologies (such as the Internet of Things, digital twins, etc....
