Abstract

With the in-depth integration of informatization and industrialization, as well as the rapid development of the Internet of Things (IoT), the deployment methods and communication protocols of workshop-level industrial control systems have become increasingly complex. Constructing dedicated industrial control system networks to integrate different devices and systems has raised higher requirements for the real-time performance, accuracy, and stability of information transmission in digital workshop network systems. This paper, based on the requirements for integration and interconnection of digital workshops, designs a dual-core redundant "ring + star" hybrid network topology structure. By independently designing the production control network and the production management network, it meets the business requirements of different industrial control systems and production management systems, effectively reduces the failure rate of workshop networks, enhances the reliability of information transmission between devices and systems, and lays a foundation for the stable operation of various businesses in digital workshops.
