摘要
提出了一种基于快速傅立叶变换的数字信号处理的方式,能够识别出轨道信号的频率变化以及其中的低频成分,用于列车控制系统的信号输入,实现自动过机校正功能。
A digital signal processing based on fast Fourier transform is proposed in a way that can identify the frequency changes of track signals and the low frequency components in them for the signal input of train control system to realize the automatic over machine correction function.
