The full name of the remote terminal unit RTU is Remote Terminal Unit. It is a device for data collection and wireless transmission in a long communication distance and harsh environment. It has remote data collection, control and communication functions. It can receive operating instructions from the host computer and control the execution of the terminal. The mechanism moves to complete the "fou···

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···

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 ···
