Application areas of industrial gateways

　　Industrial Gateway: A computer system or device that acts as a transformational task. Moving data between two systems that use different communication protocols, data formats or languages, or even completely different architectures, is the most complex network interconnection device. Incorporating edge computing, in addition to the basic protocol conversion function, it also has the following functions: it can actively collect and transmit data, analyze data, and filter and aggregate data.

The functions realized by the smart gateway

　　1) Ability to perceive network access. The smart gateway first has the function of acquiring information such as the attributes and status of each node, that is, it can perceive the real-time status of each node. Secondly, it has functions such as remote control, wake-up, and diagnosis of nodes.

　　2) Interoperability of heterogeneous networks. Smart gateway access must have requirements for cross-domain communication, so a complete addressing technology is needed to ensure that the information of all nodes can be accurately located and inquired.

　　3) Communication and data format standardization. The intelligent gateway must realize the protocol conversion from the sensor network to the traditional communication network, uniformly encapsulate the standard format data transmitted on the protocol adaptation layer, unpack the data sent by the wide area access layer into standard format data, and realize the command Analysis, and then converted into signals and control instructions that can be recognized by the perception layer protocol.

　　Industrial gateway application environment

　　In the industrial scene, the industrial IoT gateway can realize the standardized access of complex machine types on site. It can not only perform calculation and storage in the data center, but also realize remote control, remote maintenance, and remote release. Industrial Internet of Things gateway can realize remote maintenance and management of engineering machinery and technological process system, remote maintenance and management of water treatment equipment in equipment remote and maintenance.
