RTU (Remote Terminal Unit), the English full name is RemoteTerminalUnit, and the Chinese full name is Remote Terminal Control System, which is responsible for monitoring and controlling on-site signals and industrial equipment.

RTU (Remote Terminal Unit), the English full name is RemoteTerminalUnit, and the Chinese full name is Remote Terminal Control System, which is responsible for monitoring and controlling on-site signals and industrial equipment. RTU (RemoteTerminalUnit) is the core device that constitutes an enterprise's integrated automation system. It is usually composed of signal input/output modules, microproce···

RTU's hardware mainly includes functional modules such as CPU, memory, and various input and output interfaces. These modules are integrated into the circuit board, and the functional modules of the RTU are connected through the circuit board wiring. The CPU is the central system of the RTU controller, responsible for processing various input signals, and after arithmetic processing, the output is···

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···

Looking at the world, there are currently a very large number of equipment providers for Ethernet switches and industrial routers. Considering the importance of these two types of core network equipment, analysts suggest that the supplier's product quality, technical strength, innovation ability, service ability, distribution ability, brand reputation and other aspects should be considered compreh···

In early 2020, a new crown pneumonia epidemic broke out globally. In order to limit the further spread of the epidemic, strict population movement control was implemented nationwide. Remote non-contact and online economic models have been rapidly applied during the epidemic, such as remote monitoring, remote office, online education, etc., all developed rapidly due to the epidemic and accepted by ···

​ The industrial router supports serial port DTU, wired/wireless dual backup functions, and supports 5G/4G/WIFI/VPN and other networking; it is suitable for multi-channel big data, picture, and video data transmission in industrial field remote monitoring. It has 4 LAN ports, 1 WAN port, 1 RS232 and 1 RS485 (optional); the WAN port can be customized as a LAN port and expanded to 5 LAN ports; the ···

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···
