What is a DTU?
DTU is the abbreviation of Data Terminal Unit (DTU). In a broader sense, the module unit responsible for sending data information at both ends of the transmission link is called DTU, which is responsible for format conversion and data collation, and verification of the transmitted information;
In a narrower sense, DTU generally refers to the lower GSM/UMTS transmitting terminal equipment in wireless communication.
DTU is a kind of wireless terminal equipment specially used to convert serial data into IP data or convert IP data into serial data for transmission through a wireless communication network, which is widely used in meteorology, hydrology and water conservancy, geology, and other industries.

wireless data transmission, the transmission of objects are equipment and data centers or
equipment.
What is a DTU’s working principle?
DTU connects terminal equipment through the interface to obtain data, and then wirelessly
transmits it through the operator's network (2G/3G/4G) to the designated data center or
equipment. At the same time, the reverse data center can also send data or instructions to the
DTU through the carrier network, which is then sent to the terminal device through the interface.
What is a DTU product type?
By communication mode, DTU generally adopts communication modes such as
GPRS/4G/NB-IoT/LoRa/WiFi, etc. Customers can choose the best communication mode according
to their application scenarios; by interface type, DTU generally supports RS485, RS232, I/O, and
other interfaces, and customers can choose the appropriate interface type according to the
interface of their front-end collection devices.
In addition, there is another kind of embedded DTU, which is not very different from the
general-purpose DTU in terms of function, the main difference is that there is no shell, it is a
piece of an embedded motherboard, and customers can dock and integrate it into their own
front-end acquisition equipment.
What is a DTU application?
DTU has been widely used in electric power, water conservancy, environmental protection,
meteorology, transportation, logistics, industry, etc. It has helped the information and industrial
integration between industries and also gradually developed into the core technology of IoT
applications.
What is the role of 4G DTU?
The biggest role of 4G DTU is to realize the wireless transmission of data, transmitting data from
the front-end to the back-end without loss, and realizing the remote query and control of
equipment and data.
Using the lossless transmission function of 4G DTU, it can be applied in power distribution
automation to realize the collection and monitoring of power grid data, real-time monitoring of
line voltage, line current, zero sequence current, equipment status, and other operation and fault
information, data collection, monitoring and control, control center and distribution dispatch
automation system (SCADA) communication.
DTU can be used to realize real-time monitoring of distribution data, improve the reliability and
quality of power supply, shorten accident processing time, reduce the scope of a power outage,
improve the economy of distribution system operation, and reduce operation and maintenance
costs.
The use of 4GDTU can maximize the economic benefits of enterprises, improve the management
level and efficiency of the entire power distribution system, and improve the level of service for
users.
4G DTU is equipped with multiple interfaces, supporting I/O, ADC, TTL/RS-232/RS-485 interfaces
(TTL level serial port can be customized), compatible with all serial port downstream machines,
and can be flexibly combined through software configuration, which not only has the internal

data management function of the terminal but also can forward the data of power meters, PLC
and DC screen in the distribution room or opening/closing station externally. It can communicate
with the main station system through a standard unified interface to complete data transmission.
4G DTU Technology deployment
The 4G DTU wireless terminal is connected to the primary circuit, secondary circuit, switchgear,
load switches, transformers, relays, contactors, and other equipment of the intelligent ring
network cabinet, so that the staff of the monitoring center can view the operation status of each
equipment in real-time and determine the fault point and send technical personnel immediately
if there is any equipment failure.
4G DTU realizes real-time data collection and control function of distribution network, etc. It
collects real-time status and transmits it to the main station, and sends various control
information to the collection terminal at the main station to realize the remote control function.
4G DTU distribution terminal meets the requirements of data transmission and also realizes the
function of data storage and recording, which successfully solves the problem of compatible
coexistence of measurement and control, protection and communication, and achieves the
simplification of station-end equipment types. The purpose is to simplify the types of equipment
at the station.
