feeder remote terminal unit,
dsp digital signal processor
DTU power distribution network feeder automation device is used for terminal monitoring for RMU, small switching station,can connect with master station and realize the electrical signal gathering and control from multi-lines, fault detection, fault area location, isolation and non-fault area power restore to improve power supply reliability.
DTU power distribution network feeder automation device is with a hardware platform of 32 bits of microprocessor of high-performance, is with embedded real-time operation as a software development platform, also with characters of high stability and reliability , high performance,high intensity and low cost and easily installation.
DTU provides enough communication interface( 4 technical grade RS232 Serial ports, 2 of them can be equipped as RS485 ports,2 pieces of 10M Ethernet port,1 piece of USB port),main processor adapts technical grade 32 bits of high-performance processing chip, with specialized maintenance software, also can be remotely kept maintenance by specialized network, such as each CPU module is realized by bus. Main CPU module is as master station to control the whole communication process, the gathering CPU Module is as subsequent station, the communication rates is above 9600bps. Several device constitutes Ethernet bus through inner embedded industrial grade switch to make sure data processing and data exchange with sufficient bandwidth.
The TYHD-DTU distribution automation remote terminal (hereinafter referred to as the distribution terminal) is a new generation of power distribution terminal based on the latest generation of automated remote terminal technology
