Assembly workshop virtual-real fusion operation and control method based on digital twinning technology

Abstract

The invention discloses an assembly workshop virtual-real fusion operation and control method based on a digital twinning technology, which comprises the following steps: packaging various physical resources into a software agent by using a packaging technology, and using the agent which corresponds to a physical entity and is represented as a digital model as an interactive interface of a physical workshop and a digital twinning workshop; meanwhile, establishing a management and control platform for personnel operation to manage a digital twinborn model; in a task allocation stage, the intelligent agent participates in decision making and updates a result to the digital twinborn model; in the workshop operation stage, the physical workshop state and assembly data are intelligently sensed in real time, the digital twin model is updated, and real-time decision is made and operation of physical workshop equipment and resources is controlled; for the situation that people need to make decisions or process, the intelligent agent feeds back events to workshop personnel in time through the management and control platform, the personnel control a physical site through a digital twinborn model, virtual-real fusion operation of the assembly workshop is achieved, the workshop intelligent level is improved, the management and control efficiency is improved, and therefore the workshop production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of intelligent manufacturing, and in particular relates to a virtual-real fusion operation and control method of an assembly workshop. Background technique [0002] Assembly is an important link in the manufacturing process. Taking aircraft assembly as an example, it mainly completes the aircraft assembly work according to the design requirements. Due to the difficulty and complexity of aircraft assembly technology, there are many uncertain factors on site, and the management and control mainly rely on human experience. Therefore, in the assembly process management, digital technology needs to be deeply integrated into the aircraft assembly process. [0003] Based on the physical workshop entity, the digital twin technology constructs a virtual workshop that can truly reflect the real state of the physical workshop, collects real-time data of the physical workshop, and realizes the mapping of the virtual wor...
