摘要
本文系统介绍了铁路发码设备产生的移频信号及其特点,并对其进行了频谱分析,针对其频谱特征提出了一种利用DSP技术和器件对轨道移频信号进行检测的方法,并给出了系统的结构框图和软件流程图,通过使用MATLAB/SIMULINK作仿真分析,证明了方案的可行性,同时结合实际分析了系统的实时性。
This paper analyzes the characteristics of FSK signal and describes the method of FSK signal detecting with DSP technology and DSP device according its frequency spectrum features. It also puts forward the composition of the measurement system and its software flow chart. Through large numbers of computer simulation and experiments, both reality and real-time response of the system are proved.
