Abstract

The invention discloses a method for dynamic linkage control of an autonomous production process of an intelligent workshop based on digital twin. The method comprises the following steps of (1) constructing a digital twin model of an intelligent workshop entity in an information space, and establishing a virtual and actual mapping relation between an entity and the model; (2) establishing a bidirectional data transmission channel to realize virtual and actual linkage; (3) acquiring real-time state data of manufacturing resources and uploading the real-time state data to the digital twin modeland updating; (4) carrying out real-time simulation on an operation state of the intelligent workshop, and calling an algorithm to predict an optimal solution of a machine tool task arrangement sequence and executing a machine tool number of the next procedure; (5) analyzing the optimal solution, and issuing to each manufacturing resource entity in the intelligent workshop in a form of a production instruction through a bidirectional data transmission channel; and (6) repeating the steps (3) to (5) until all the working procedures of a workpiece are processed. The dynamic linkage control of the autonomous production process of the intelligent workshop is realized through synchronous linkage.

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....
