The premise of studying what is the difference between 5G industrial gateway and 5G DTU is to better understand the concept of industrial IoT. The industry is gradually developing towards intelligence. The Industrial Internet of things, as the name implies, is the connection of equipment to things via the Internet. To be connected, the device needs to be able to connect to an intelligent terminal, after that, the platform for data interaction is needed, with features such as data collection, data transmission, and remote debugging.
Industrial IoT can be simply divided into four stages: terminal stage, connection stage, interaction stage and application stage. But with the development of electronic control technology, many devices have control devices on them, such as PLCs, controllers, control boards, etc. These are used to connect to the network. Some simple industrial devices do not have control devices, then they need to install network terminals, such as data collectors, network sensors, etc. Most of the electronic controls cannot communicate with the Internet, so a gateway must be installed to connect to the Internet.
Although both 5G Industrial Gateway and 5G DTU play the role of gateway docking, they work differently.
5G DTU is a kind of serial data to IP or IP data transmission using wireless network. Fast and flexible networking, low cost construction cycle, wide network coverage, good confidentiality; link supports always-on, traffic billing, low cost for users.
The 5G Industrial Gateway has the ability to collect, analyze, standardize, and upload data from field devices through multiple interfaces such as serial, network, and io. Utilizing MQTT protocol and edge computing technology, it enables highly concurrent platform access while supporting multiple device protocol drivers, providing users with a reliable data channel and standardized field data.
The difference between 5G DTU and 5G industrial gateway can be simply understood as 5G industrial gateway is a more powerful wireless communication device than 5G DTU. 5G DTU usually simply supports data general encryption transmissions. While 5G industrial gateways have more interfaces, rich protocol library, stronger expansion of device access capability, data caching to disk, once the network is restored, it will be transmitted to the server, and the data will always remain the same. At the same time, remote management and remote update functions are also available.
While the 5G DTU can only transmit data, the 5G Industrial Gateway is able to process the collected data, for example by loading it in an agreed message format.
