| 摘 要： | 车载信号的检测是保证列车安全运行的重要手段之一.在具体分析国内车载FSK信号的特点及其存在的主要干扰之后,针对车载FSK信号干扰严重的实际情况,选用了混频滤波法对信号进行低频调制波的解调,并在硬件上采用DSP芯片TMS320VC5402和单片机89C52相结合的主从式结构成功实现对车载FSK信号的检测.

| Abstract: | The detecting of the train signal was an important way to guarantee the safety of the railway. After analysing the characteristic of the FSK signal and the disturbance, it was selected an appropriate way to process the signal, and also designed a detecting device based on DSP and SCM, in which the DSP was mainly for the signal processing and the SCM for the I/O input and output. |
