Software Platform Dsp Digital Signal Processor Self Test With Channel Monitor

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 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.
