1. Realize the interconnection and intercommunication of production and manufacturing equipment. The communication network connects field devices, controllers, HMI, monitoring systems and enterprise management systems. It is the information transmission channel in the industrial production system and plays an important role in the stability and reliability of the industrial production system. At present, industrial network technology is developing in the direction of modern network technology——industrial Ethernet technology and industrial Internet. The use of civilian common Ethernet technology cannot guarantee the integrity of industrial Ethernet implementation, and it is difficult to meet the reliability requirements of industrial-grade communication. Therefore, special training equipment is required

2. Cultivate professional industrial Ethernet and industrial Internet engineers. Through specialized training equipment to meet the needs of industrial development.

1. Input power: three-phase five-wire ~380V±10% 50HZ

2. Leakage protection: I△n≤30mA, t≤0.1S

3. 380V three-phase five-wire output power supply

4. 24V DC power output, analog signal source

5. Emergency stop button, power supply indication, power supply indication

6. Protection against power failure and wrong power on

7. Working environment: Temperature -10°C~+40°C Relative humidity <85% (25°C) Altitude <4000M

8. Equipment Workbench

Constructed of industrial aluminum profiles, with wheels at the bottom, the overall equipment is light and strong, generous and beautiful; the design conforms to the principle of ergonomics, and the operation and use are more convenient. It is made of sheet metal and industrial aluminum profiles, which is atmospheric and beautiful.

The mesh board or panel structure is adopted, which is ergonomically designed. It should have a multi-functional power box to ensure power supply. It is required that the components be arranged on the mesh board or panel, which is intuitive and reusable.

The overall structure and functions of the Industrial Internet training room
The system is based on the Siemens four-network structure:

The first layer is “enterprise management”, which conducts overall scheduling and data management of the entire network system, and intelligent production management through mobile terminals and server terminals.

The second layer is the “operation level layer”, with MES as the main control system, real-time monitoring and operation of data through the host computer.

The third layer is the “control layer”, which is mainly composed of 1200PLC, 200SMART, H5UPLC, smart touch screen, etc. It is used for the analysis, calculation, processing and logic control functions of the bottom data, and realizes the upload and release of data;

The fourth layer is the “on-site layer”, which is mainly composed of remote station instruments, servos, frequency converters, sensors and other hardware as well as 3D virtual workstations to simulate the production process of the production line.

Different levels are connected by network management switches with different functions, which have strong network protection functions!

The network structure topology of the industrial automation network training platform is shown in the following figure:
