DTU has been widely used in power, environmental protection, LED information release, logistics, hydrology, meteorology and other industries. Although the application industries are different, the principles of application are the same. Most of the DTUs are connected to industrial equipment, such as PLCs, microcontrollers and other automation products, and then establish a wireless communication c···

This computer is used to set and adjust the parameters of the DTU. At the same time, when testing, it can connect to the DTU as a virtual data source device, and send and receive data with the host computer data center through the serial port debugging tool.

The communication between the DTU and the server is initiated by the GPRS DTU (client), and the server responds to the DTU by sending back feedback or accepting communication. The DTU end and the server end together form an application system based on GPRS and INTERNET network communication.

DTU equipment belongs to the lower-level computer, and the data center responsible for processing DTU return information is the upper-level computer. The typical application method is that multiple DTUs correspond to one data center. However, the upper computer and the lower computer do not necessarily have a one-to-one correspondence. They can be one lower computer corresponding to one or more up···

The data transfer unit DTU (Data Transfer Unit) is a wireless terminal device specially used to convert serial port data into IP data or convert IP data into serial port data for transmission through a wireless communication network.

RTU has excellent communication capabilities and larger data storage capacity, especially suitable for harsh temperature and humidity environments, and provides more complex calculation functions. RTU is a typical application in the field of environmental monitoring, which can collect, save and transmit field data, and can also realize the functions of remote control, remote signaling, and remote ···

According to the different data transmission methods of DTU, DTU can be divided into 4 types: GPRS DTU, WIFI DTU, CAN DTU, 4G DTU.

Compared with the commonly used programmable controller PLC, RTU usually has excellent communication capabilities and larger storage capacity, is suitable for harsher temperature and humidity environments, and provides more computing functions. RTU products are widely used in SCADA systems in industries such as oil and gas, water conservancy, power dispatch, and municipal dispatch.

The Wi-Fi Alliance stated that Wi-Fi 6E will be particularly suitable for AR and VR, and it will also help solve the problem of insufficient Wi-Fi spectrum. It can provide continuous channels that can accommodate 14 additional 80MHz channels and 7 additional 160MHz channels Spectrum block, due to more channels and wider spectrum space, interference between Wi-Fi networks will also be reduced. Alth···
