Application and function introduction of industrial intelligent gateway

Introduction to the functions of industrial smart gateways What projects are suitable for industrial gateways

　　The intelligent gateway has functions such as data interaction management. Compared with ordinary gateways, its functions are more powerful. Common smart gateways include industrial IoT smart gateways, smart home gateways, and automotive smart gateways.

Application of Industrial Smart Gateway:

　　Industrial intelligent gateway is suitable for water, gas and steam pipe network monitoring; EMS (energy management system) signal collection and transmission; municipal water supply and drainage pipe network, pipe trench monitoring; underground pipe gallery environmental monitoring. Production process signal acquisition and data transmission of manufacturing and processing enterprises; MES (Manufacturing Execution System) signal acquisition and data transmission; environmental monitoring of hazardous chemical sites. Atmospheric environment monitoring signal collection and data transmission; agricultural greenhouse environment monitoring signal collection and data transmission; breeding environment monitoring signal collection and data transmission; medicine and food storage environment monitoring signal collection and data transmission.

　　The responsibility of the industrial gateway is to collect data. At the same time, because of the needs of the industrial cloud platform, it also assumes the mission of connecting automation and IT. It can be said to be a product that connects the past and the next.

　　 Although it is said that sensors are the sensing devices at the bottom of the Internet of Things, some people think of sensor manufacturers first when they think of data collection. However, actually speaking from the business side, in the practice of the Industrial Internet of Things, how to connect to the controller is the first problem to be solved. Because there are already a lot of available data in the controller, these data are closely related to the equipment's faults, status, process parameters, energy consumption parameters, etc. At the same time, in some application scenarios, it is necessary to issue commands to the controller (issue formula, start and stop, modify process parameters, etc.)

　　 Therefore, the connection of the controller is the primary consideration on the business side. However, the sensor is more because the data latitude on the controller side is not enough, or some new applications and new equipment or equipment without a controller (either very old or partial mechanical equipment) will become the first consideration.

　　The traditional approach is generally to use SCADA software in the automation system to collect local equipment and store it in the corresponding database. Then the IT system uses the database docking to collect data. This is not only costly (especially for equipment-based equipment operation and maintenance), but also low in efficiency. Therefore, industrial gateways have gained more market.

　　The traditional SCADA market will gradually slow down. At the database and data display level, IT systems have more powerful configuration capabilities (high concurrency, distributed storage, H5 technology, 3D, etc.), and at the protocol level, they are more flexible. Alternative to the industrial gateway.

　　 Generally speaking, industrial smart gateways need to have the following capabilities:

　　1. It has the ability to analyze the next (automation system) protocol (communication protocol: Modbus, PPI, MPI, CNC, etc.; bus protocol: CAN, PROFIBUS, etc.; industrial wireless protocol: WirelessHart, 433, etc.). The current gateway uses the communication protocol as Mainly, only a few manufacturers will consider the next bus protocol and wireless protocol. At the same time, the traditional bus protocol conversion is also called an industrial gateway, and the gateway is not clear.

　　2. It has the ability to connect with the protocol (IT system), and the communication capabilities (Ethernet, WIFI, 5G, 4G, NB-IOT, etc.).

　　3. Possesses the ability of secondary development of private agreements on the upper and lower sides.

　　4. Capable of data caching and local computing (fog computing/edge computing).
