摘要
提出了一种基于FPGA实现的直流相位跟踪检测系统,分析了系统输出信号与输入信号保持同步的实现原理,并建立了基于FPGA的设计模型,进行了硬件仿真,确定了系统的采样率,最后通过实验验证了此FPGA系统可实现相位实时检测,误差为0.2%,证明了此系统可满足干涉式光纤电压传感器对相位检测的性能要求。
A direct current phase tracking detection system based on FPGA was proposed.It was analyzed that the principle how the output signal kept pace with the input signal.A design model based on FPGA was set up,and the hardware simulation was executed to decide the system sample rate.Finally,it was verified the FPGA system could realized the real-time detection of the phase by the experiment,and the error was 0.2%.It is certified that the system can meet the performance needs of the phase detection in the interferometric fiber-optic voltage sensor.
