Introduction to 5G Smart Gateway Application Solution

　　 The IoT gateway is also an industrial Ethernet serial port smart gateway, and an RS485 serial port Modbus RTU smart gateway is a wireless sensor network product. The IoT gateway can integrate the data collected by different terminals and transmit it to the next level to complete the transmission of information between each level. The IoT gateway can realize the protocol conversion between perception networks and communication networks, as well as between different types of perception networks; it can realize both wide area network communication and local area network communication. So what functions does the smart gateway have?

　　The smart gateway mainly implements the following three functions:

 　　 The ability to perceive network access.

 　　The gateway of the Internet of Things 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. The second is to have the functions of remote control, wake-up, and diagnosis of the node, that is, to realize the automatic management of the node.

 　　The ability of heterogeneous network intercommunication.

　　 Internet of Things gateway access must have requirements for cross-domain communication, so perfect addressing technology is needed to ensure that the information of all nodes can be accurately, efficiently, and safely located and inquired. With the development of Internet of Things applications, the number of node addresses will gradually increase, and their coding structure is different from the domain name structure in DNS. Therefore, a set of addressing technologies different from the Internet is required to meet the demand.

　　 Communication and data format standardization.

The 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 command analysis , And then converted into signals and control commands that can be recognized by the perception layer protocol.

　　 Industrial IoT Smart Gateway Application Solution

　　 1. It is suitable for vegetable greenhouses, gardening greenhouses, flower greenhouses and other petrochemical companies such as hazardous chemicals (dangerous goods) warehouses, oil storage tanks (tank area), etc.

　　 The wireless sensor is wirelessly transmitted to the computer room through zigbee, and the collected data is viewed and stored through the software, and the collected data is automatically controlled to complete the agricultural automation monitoring system.

　　2, suitable for parks, scenic spots, schools, large shopping malls, supermarkets, etc.

　　Temperature and humidity sensors, light sensors, soil moisture sensors, wind speed and direction sensors, rainfall sensors, etc. are connected via RS485 bus, and the bus is connected to the GPRS host, so that data is transmitted through the network, and the data can be viewed on the office network for recording and alarming functions.

　　3. It is suitable for breeding pigs, chickens, ducks, cattle, geese, sheep and other farms.

Temperature and humidity sensors, light sensors, carbon dioxide sensors, hydrogen sulfide sensors, ammonia sensors, etc. are connected through the RS485 bus. Each animal husbandry plant provides power. The bus is connected to the RS485 to Ethernet module, so that the data is transmitted through the network. Network view data, record and alarm functions.

　　4. Monitoring system for dust and noise in construction site dust control area-site road and construction work area

 　　 One of the more prominent problems in construction is dust pollution. There are many reasons for this pollution, including the weak environmental protection awareness of construction workers, the lack of corresponding management mechanisms for construction, and the failure of supervision units to effectively perform their own functions. In order to effectively control the construction dust, practical technical strategies must be adopted to enhance the environmental protection awareness of construction personnel and implement the dust control technology.
