IIoT is a key link in the process of enterprise digital resource planning (ERP), manufacturing execution
transformation, which accelerates the integration of various system(MES), computer aided quality (CAQ), computer
elements of information technology (IT) and operation aided manufacturing (CAM), Internet process connection
technology (OT). Data is the most important binder in the (IPC), symbolic programming system (SPS) and
integration process. In order to make the IT and OT integrate computerized numerical control (CNC), and so on. Figure 3

and mode innovation. The digital twin just provides the sensors. After high real-time data exchange, the state of the
interface of data and technology for the development of real object is simulated by digital twins, and the
integration. corresponding fault diagnosis results, evaluation and
prediction results, behavior control of machinery and other
information are obtained. Then the high real-time network
communication and the corresponding result information are
used to control the production process. The high-real-time
data exchange between them is the basis and prerequisite for
the application of the digital twins technology. In addition,
as an effective way to solve the interaction theory and
implementation method of the physical world and the
information world in the future, digital twins are gradually
deepening in practice. This also means that the demand for
network performance in its development is constantly
improving, and it also promotes the improvement of IIoT
related project research and standards. Thus, it is necessary
to further study the low latency and high reliability of IIoT
in Section 3.

Based on the above case, digital twins can display, predict,
and analyze the interaction between a digital model and the
physical world. The design based on digital twins is based on
virtual mapping of existing physical products. A large
amount of data is studied to obtain valuable knowledge for
product innovation. Designers only need to publish the
requirements to the industrial Internet platform, so that
platform managers can precisely match the data services
needed by designers, as well as the model and algorithm
