Overview of the principle of 5g industrial gateway. What are the classifications and characteristics

1、 5g industrial Internet of things gateway

5g industrial Internet of things gateway is applied to industry. Industrial Internet of things is different from other Internet of things technologies. Industrial Internet of things focuses on connecting machines and equipment in oil and natural gas, power utilities and other industries, rather than consumer products such as general home intelligent gateway. Industrial gateway is the core component of Internet of things and industrial control system.

The gateway serves as a connecting link between the preceding and the following.

Upper computer, computer or touch screen monitoring system, MES;

The lower part is the lower computer, including PLC, sensor, embedded chip, etc.

Gateway plays an important role in communication between upper and lower computers. Its basic function is protocol conversion. The gateway will summarize all the data, convert the protocol of the sensor, and preprocess the data before sending it.

2、 Features of 5g industrial Internet of things gateway

1. It has the ability to analyze the downstream (Automation System) protocols (communication protocols: modbus, PPI, MPI, CNC, etc.; bus protocols: can, PROFIBUS, etc.; industrial wireless protocols: WirelessHART, 433, etc.). At present, the gateway is mainly based on communication protocols, and only a few manufacturers will consider the downstream bus protocols and wireless protocols. At the same time, the traditional bus protocol conversion is also called industrial gateway.

2. It has the protocol docking capability for the upper (IT system) and the communication capability for the upper (Ethernet, WiFi, 3G, 4G, nb-iot, etc.).

3. Capable of secondary development of upper and lower private agreements.

3、 5g industrial Internet of things gateway classification

5g industrial gateway functions can be divided into two categories from the appearance of the industrial gateway:

1. Pure industrial gateway

The industrial gateway bridges different network environments and transfers data from different network environments to the cloud for data processing.

2. Industrial gateway with data acquisition function

In addition to the bridging function of different network environments, this industrial gateway also performs data acquisition and input / output control of external environments. Smart factory and other industrial 4.0 applications.
