Distribution automation terminal dtu The
distribution automation terminal dtu collects real-time operation data of the distribution network and sends it to the distribution network automation system so that the upper-level master station system can monitor the distribution network operation at any time and make correct decisions. At the same time, the distribution network equipment can be operated remotely through the master station system, thereby shortening the troubleshooting time and reducing the cost of manual maintenance.
Distribution automation terminal dtu function
1. The DTU function module monitors line voltage, line current, zero sequence current, equipment status and other operation and fault information in real time, completes remote signaling, remote measurement, and remote control functions, and realizes real-time monitoring of distribution network automation.
2. The device has RS232 interface, RS485 interface, 2 analog input interfaces, 3 GPIO, which can be configured as input and output, and the communication protocol is diversified and compatible with various power distribution automation systems.
3. Multiple watchdog design, multiple link detection, remote maintenance, upgrade management, high standard EMC electromagnetic compatibility, stable work in strong electromagnetic environment.
4. Support power IEC101/IEC104 protocol transmission to meet the needs of various power master stations and automation terminals; support ModbusTCP/Modbus RTU protocol conversion, suitable for industrial SCADA and various industrial equipment.
5. Full Netcom/4G/3G/2G, supporting overseas operator networks, making more choices and more convenient.
6. Built-in PPP, TCP/IP, UDP/IP, MODBUS-TCP, MODBUS-RTU and other protocols, compatible with the manufacturer's private protocol.
7. When the network signal or the central network is paralyzed, it can automatically switch to GSM short message mode to send and receive data.
