Production line control system and method based on digital twinning, and production system

Abstract

The invention discloses a production line control system based on digital twinning, and the system comprises a data collection subsystem which collects the current operation state data of a productionline in real time; a virtual twinning control subsystem which is used for generating a digital twinning model representing physical equipment at each station of the production line according to the historical operation state data of the production line and the current operation state data of the production line; a data analysis subsystem which generates new operation state data according to a recommendation algorithm, the historical operation state data of the production line, the current operation state data and the target operation state data of the production line. The digital twinning model simulates the operation state of the production line according to the new operation state data, and the data analysis subsystem is further used for finally generating optimal operation state data according to a simulation result of the digital twin model. The system also comprises an edge computing gateway which is used for realizing data interaction between the virtual twinning control subsystem and the data acquisition subsystem.

Description

technical field [0001] The invention belongs to the field of automated manufacturing, and in particular relates to a digital twin-based production line control system, method and production system. Background technique [0002] Digital Twin, DT for short, is an emerging concept. DTs are usually produced simultaneously with real devices and systems, such as processing equipment and sensors. DT can be used to represent a digital model of a device in the real world, making it identical in state and behavior to the actual corresponding machine. [0003] Existing production lines employ a human-machine interface (HMI), which typically consists of a simple command system, or a simple graphical user interface (GUI) to select options through menus, enter specific data or commands, and view sensor data from a single device. However, the data generated by the production line and the operation of the entire system may be very complex, and the performance of this production line is of...
