摘要
为快速准确地测试ZPW2000移频轨道电路信号参数,论文基于STM32单片机,通过欠采样方式以及快速傅里叶变换(FFT)解调算法,设计ZPW2000移频轨道电路信号载波频率和低频调制频率等的检测方案。
In order to quickly and accurately test the signal parameters of ZPW2000 frequency shifting track circuit, based on the STM32 single-chip microcomputer and by means of the under-sampling and fast Fourier transform (FFT) demodulation algorithm, the detection scheme of ZPW2000 frequency shifting track circuit signal carrier frequency and low-frequency modulation frequency is designed.
