On the premise of studying the difference between 4G industrial gateway and 4G network port Cellular modem, we can first understand the concept of industrial Internet of Things. Industry is gradually developing towards intellectualization. The industrial Internet of Things, as its name implies, is the connection of industrial equipment. The connection here refers to the Internet connection. To connect, it is necessary to have a connectable device intelligent terminal. After connection, it needs a platform for data interaction. Commonly used data interaction includes data acquisition, data delivery and remote debugging.
The industrial Internet of Things can be simply divided into four stages: terminal stage, connection stage, interaction stage and application stage. However, with the development of electronic control technology, many devices have control devices, such as PLC, controllers, control boards and so on, which are used to connect to the network. Some simple industrial equipment does not have control devices, so it is necessary to install network terminals, such as data collectors, network sensors and so on.Most electronic controls cannot communicate with the Internet, so a gateway must be installed to connect to the Internet.
Although the 4G industrial gateway and the 4G network port Cellular modem both play the role of gateway docking, their working principles are different.
4G network port Cellular modem is a kind of wireless network to realize the transmission of serial port data to IP or IP data. Fast and flexible networking, low-cost construction cycle, extensive network coverage and good confidentiality capability; The link supports always online, traffic billing, and low user cost.
4G industrial gateway has the functions of data acquisition, analysis, standardization and uploading of field devices through serial port, network port, io and other interfaces. By using MQTT protocol and edge computing technology, the platform access with high concurrency is realized, and the protocol drivers of various devices are supported at the same time, which provides users with reliable data channels and standardized field data.
Difference between 4G network port Cellular modem and 4G industrial gateway
The difference between 4G network port Cellular modem and 5G industrial gateway can be simply understood as that 5G industrial gateway is a more powerful wireless communication device than 5G network port Cellular modem. The 5G network port Cellular modem usually simply supports the general encryption and transparent transmission of data.The 5G industrial gateway has more interfaces, rich protocol libraries, stronger device access and expansion capabilities, data cache to the disk, once the network is restored, it will be transmitted to the server, and the data will remain unchanged. At the same time, it can also carry out remote management, remote update and other functions.
4G Cellular modem can only transmit data transparently, while 5G industrial gateway can process the collected data, such as loading according to the agreed message format.
