摘要
本文介绍了目前交流计数机车信号存在的问题,阐述了数学模型的建立,以及计算机的选择,着重提出通过计算机实现快速富立叶变换FFT,可进而实现不同频率的交流计数机车信号的自动识别。
After summarizing the problems existing in A. C. counting cab signalling, we discuss in detail the establishment of mathematical models and the selection of the computer to be used. It is emphasized that on a computer can be realized the Fast Fourier Transformation (FFT) and thereby can also be realized the automatic identification of A. C. counting cab signals of different frequencies.
