Comment utiliser le DTU 4G et ses caractéristiques fonctionnelles

1. What is 4G DTU ?

4G DTU is a data transmission unit, which is commonly understood as a piece of hardware used to transmit data. Since it is used to transmit data, it can be regarded as a pipe, that is to say, instructions are passed to the device through it, and the pipe does not respond to these instructions.

2. How to use 4G DTU?

4G DTU has input and output wiring ports. In addition to these physical wiring ports, 4G DTU can also wirelessly transmit data to the designated server. Generally speaking, every 4G DTU manufacturer will have corresponding documentation and configuration tools. However, this serial port debugging tool has already prepared some configuration instructions. You can configure the 4G DTU by just clicking a button. The so-called configuration refers to specifying the IP and port of the server through this configuration tool.

3. What are the functional features of 4G DTU?

Always online: 4G DTU data terminal can maintain connection with FDD-LTE/TDD-LTE network, and can detect network status in real time to keep communication links open;

Automatic dialing: When the 4G DTU and network link are interrupted due to network or external power shutdown, the 4G DTU can automatically start dialing and reconnect to the network designated IP.

Transparent transmission: The so-called transparent transmission refers to the transmission of user data through the network. When it reaches the serial port, it is output strictly according to the original data, without the need for the user to decode the protocol and other processing.

Standard UDP/TCP data transmission: Users can choose to use communication protocols according to the characteristics of the data. The UDP protocol is a “linkless data transmission protocol” and the TCP protocol is a “reliable data transmission protocol”. When UDP is chosen for data transmission, the data usually has repeatability characteristics. Data loss does not affect the overall situation, such as temperature, pressure, flow, GPS positioning information, etc., collected data. Data integrity and necessity are often required when choosing TCP for data transmission.

Fixed IP and dynamic domain name support: 4G DTU not only supports connection with fixed IP, but also supports dynamic domain name resolution. This feature provides a solution for users without fixed IP.

4. What are the application fields of 4G DTU?

The emergence of 4G DTU wireless communication terminals meets the needs of remote data transmission and communication, especially for industries where data collection points are scattered, remote, unattended, and cable communication installation and construction are inconvenient and costly. Such as meteorology, environmental protection, water conservancy, electricity, oil pipeline monitoring, urban pipe network monitoring, industrial monitoring, transportation, POS machines, etc. The intelligent retail industry has greatly improved data communication capabilities, saved manpower and material resources, and achieved a rapid development of data communication.
