Traditional manufacturing management is often beset by the serious “Black Box” problem

that is the inability to grasp various types of information on-site in a timely manner

which causes the actual status of the site lagging behind the expected plan and further reduces efficiency and quality. To solve this problem

the key technologies of digital twin monitoring system were studied. A three-dimensional model of the production line was established in the virtual space

and the association mapping between the data and the model was established via the collection of realtime on-site data. And then

a virtual leadership cockpit was created presenting various status and performance boards to solve the transparency of the production site and to improve production efficiency and quality.
