5.2 Connection Framework of Interconnection Network for Tires Intelligent
Manufacturing
5.2.1 The overall connection framework shall be divided into three levels. edge access layer,
aggregation layer and core layer.
5.2.2 Edge access layer, that is, through wired and wireless modes, connects the production
factors, such as personnel, machines, materials, environment and systems related to the Internet
system in the tire factory, supports the forwarding of different data formats for business
development, and realizes end-to-end data transmission. To achieve intercommunication and
interoperability between data and information elements, the protocols that should be adopted
include but are not limited to OPC UA, MODBUS RTU, MQTT, WebAPI, TCP, UDP and CC-
Link, etc.
5.2.3 Aggregation layer. it is advisable to use SDN and VxLAN technologies to design the
factory aggregation layer network. The network can be abstracted into a physical bearer
network and an application-oriented Overlay network, as shown in Figure 2.
M---Wireless Network in the Factory;
N---Mixing Equipment;

6 Interconnection Network Architecture for Tires Intelligent
Manufacturing
6.1 Interconnection Network Structural Division of Tire Factory
The interconnection network structure of tire factory should be divided into two levels. IT
network and OT network. The network level is divided into field level, workshop level and
factory level in accordance with the actual management level of the tire factory. The two-layer
three-level network structure of the tire factory is shown in Figure 4.
equipment commands, data polling and collection, the delay shall not exceed 30 ms.
b) Support flexible IT/OT networking. Realize the separation of control plane and
forwarding plane, coordinate network resource scheduling through SDN controller
and manufacturing control and support flexible manufacturing and automatic
production organization.
c) Support remote factory networking, preferably use MPLS special line technology or
SD-Wan technology, and with the capability of accessing remote factory for
networking.
d) Support IPv4 and IPv6, IT network and OT network, support IP protocol, and support
direct interconnection between IT and OT nodes.
e) Support full-node visualized management, and provide functions, such as alarm
management, performance management, report management, and audit management,
etc..
f) It is advisable to support new technologies and new solution connections, such as
TSN, 5G, WIA for industrial automation, and the sixth-generation wireless network
(Wi-Fi 6) and other new technology connection modes.

example, large Layer 2 network technology, etc.) to achieve flexible and simplified
network management;
b) Wireless networks, such as 4G/5G, NB-IoT, and wireless LAN shall be utilized to
achieve comprehensive network coverage;
c) Containerization technology (such as Docker containers, K8s, etc.) should be used to
support containerized deployment of tire factory platform application and
management system, and to achieve real-time, efficient collection, analysis and
interaction of data within the factory.
7.5 Data Communication System Implementation
The goal of data communication system deployment is to build a bottom-up, full-process, full-
business data communication system.
Intelligent manufacturing factories should support production equipment, monitoring and
acquisition equipment, dedicated remote terminal units and data servers, etc. that support
international or domestic standardized data protocols, such as OPC UA, MODBUS RTU and
MQTT; and deploy data middleware and application systems that support tire factory-specific
data structure models to achieve cross-factory / cross-regional and cross-system information
interoperability.
