Dewei Yang · Optical Communication Technology · 2010
Take NI7813R intelligent data acquisition card as the core,a optical fiber voltage transformer signal acquisition system is proposed; Using LabVIEW as programming tool,FPGA VI and HOST VI are designed in the FPGA and the host. The former is for the demodulation of the signal,while the latter is for data record-ing and real-time display. In order to satisfy the needs of network in digital substation,the acquisition system using Ethernet interface output,so a comprehensive exposition is given including hardware design,software design and finally the simulation results.
