The full name of 5G is the fifth-generation mobile communication technology, and the 5G network and 5G frequency band are completely different things in the 5G concept. It can be said that the 5G frequency band is the basic resource of 5G communication, and the 5G network is the application basis of 5G communication.

Ethernet can be connected to the internet so that it can realize long-distance communication and realize monitoring on a global scale, which is not possible with RS485.When multiple RS485 devices are needed to connect to the computer, the traditional way is to use a multi-serial port card, that is, use the extended serial port on the computer to implement multiple RS485 serial ports.

Through DTU products, devices can transmit data wirelessly. No matter how far apart they are, they can interact and process data through a wireless network.

What is the DTU in the Internet of Things? The Chinese name of DTU is "wireless data transmission terminal". According to the different transmission methods and networks used in data transmission, DTU devices can be divided into many types, such as: 4G DTU, NB-IOT DTU , LORA DTU, GPRS DTU.

Since the two IoT technologies of NB-IoT and LoRa are both low power consumption, the current consumption (peak current and average current) of the node can be more detailed.The synchronization protocol of the cellular network must also be used, and the terminal must be regularly connected to the Internet and have a short downlink delay.LoRaWAN uses the asynchronous ALOHA protocol, which needs to ···

Simply speaking, the Industrial Internet of Things:It is to realize the interconnection between the automation industry and intelligent (Smart Sensor), digital (Digital Sensor), embedded (Embeded Sensor), traditional (Dumb Sensor), and inductive (Dumb Sensor) sensors.

As we all know, at first the data was a simple process quantity of analog signal output, and then the instrument interface was RS232 interface, so that point-to-point communication can be realized, but this way cannot realize the networking function, and then the emergence of RS485 solves this problem. Therefore, this article introduces the RS485 interface in detail.

DTU wireless data transmission terminal is a kind of wireless data transmission terminal equipment with strong anti-interference ability, powerful function, convenient use, low operating cost and low cost. It adopts GPRS/4 G/NB-IoT communication technology and makes full use of the existing network. resource. So, what are the benefits of doing this?

The full Chinese name of Narrow Band Internet of Things: Narrow Band Internet of Things is what we call NB-IOT, which is mainly based on LTE technology (3GPP Release 13).

At present, DTU has a wide range of applications in industry. It mainly solves the problem of transparent transmission of data between serial devices and remote servers when there is no network outdoors, such as in the fields of electricity, energy, transportation, water affairs, and agriculture.
