One, the nature of different
1, RTU: constitute the core device of the enterprise integrated automation system.
2, DTU: dedicated to the serial data into IP data or IP data into serial data through the wireless communication network for transmission of wireless terminal equipment.
Second, the hardware composition is different
1, RTU hardware composition: RTU hardware mainly consists of CPU, memory and a variety of input and output interfaces. These modules are integrated in the circuit board, RTU functional modules connected through the circuit board wiring.
2, DTU hardware components: DTU hardware components mainly include the CPU control module, wireless communication module and power module.
Three, the application of different
1, RTU applications: for the more severe temperature and humidity environment, to provide more computing functions. rtu products are widely used in oil and gas, water conservancy, power scheduling, municipal scheduling and other industries in the SCADA system.
2, DTU applications: DTU has been widely used in electric power, environmental protection, LED information release, logistics, hydrology, meteorology and other industries. Although the application industry is different, but the application principle is the same. Most of them are connected with industrial equipment such as PLC, microcontroller and other automation products, and then establish a wireless communication connection with the background.
Extended Information:
The more professional GPRS DTUs also provide some extended features, mainly including: support for data center domain name resolution, support for remote parameter configuration, remote firmware upgrade, support for remote SMS/telephone wake-up call, and support for local serial port firmware upgrade, Provide SMS channel, provide DTU online and offline level indication, etc.
More advanced DTUs can also provide users with secondary development functions; for example; communication plug-ins, DLLs, interface documents, so that users can modify the DTU according to their own actual situation and improve the DTU products to make them more suitable for their own needs.
