Considering that the industrial automation control system has certain special requirements for data, the safety of data shall be fully considered in the design of the whole system, and the reliability of equipment shall be emphatically measured in the selection of equipment to ensure the safe and reliable operation of the whole system.

2.2 progressiveness and practicability of technology

While ensuring that industrial user applications are met, it also reflects the progressiveness nature of the wireless network system. In the network design, we should combine the advanced technology with the existing mature technology and standards, and fully consider the current situation and future development trend of wireless network applications.

2.3 Flexibility and Scalability

According to the needs and changes of future applications of industrial users, it shall have sufficient access capability and scalability, including the provision of multiple access modes and the scalability of access, the expansion of bandwidth and the smooth upgrade of rate, and the scalability of processing capability, so as to minimize the adjustment of network architecture and existing equipment.

2.4 Manageability

Considering the decentralized distribution of industrial users' lower devices and the difficulty of maintenance, the scheme adopts a centralized management network architecture to monitor the running status of the devices in real time, and the lower computers can be remotely set through the monitoring center.

2.5 Compatibility and Economy

Compatibility, which can maximize the availability and continuity of various computer software and hardware resources in the network; Economical. Under the condition of making full use of existing resources, the overall investment in the network system is minimized. It shall be implemented in a planned and step-by-step manner. Under the premise of ensuring the overall performance of the network, the existing network equipment shall be fully utilized or necessary upgrades shall be made.

3、 Network architecture description 3.2 Scheme description

Project site:

The actual project site will be composed of a variety of equipment. The operation and status of these equipment will be collected and monitored through one or more built-in Ethernet PLCs. The 4G wireless industrial router has a built-in 100Mbps Ethernet interface, which is connected with one or more Ethernet PLC Ethernet ports on the site to form a project site network. The 4G wireless industrial router can be powered by the 24VDC output of Siemens PLC, and automatically connected to the Internet after being powered on, and establish an encrypted security tunnel with the "VPN firewall" at the front of Juyuan Monitoring Center.

The safety tunnel is used to ensure that the communication data flowing to "Juyuan Monitoring Center" and "Project Site Network" are not obtained by illegal Internet users. At the same time, the "project site network" is seamlessly connected with the "Juyuan Monitoring Center", and the center maintenance personnel can directly change the configuration of the field equipment by accessing the IP address of the equipment in the "project site network".

Juyuan Monitoring Center:

Juyuan Center contains all the core applications of the enterprise. It is generally composed of wired network access (with fixed public network IP address), firewall supporting VPN access, router, and maintenance personnel.

As a manager, you can maintain or monitor the equipment on the project site manually or through the existing application services of the enterprise.
