| 摘 要： | 针对瞬态脉冲干扰容易造成铁道信号电气产品产生误动作或损害等实际情况,根据瞬态脉冲信号时域特点采用双指数函数进行建模仿真,通过傅氏变换把时域信号转换为频域信号,利用最大包络法在频域对瞬态脉冲干扰信号的特点进行分析,并结合频域的特点给出一些抗干扰对策,来提高铁道信号设备的安全性和可靠性.

| Abstract: | For the actual situation of railway signal electrical products taking place false action or damage caused by transient pulse interference, etc., this paper adopts the double exponential function to conduct the model and simulation according to the time domain features of transient pulse signal. Time domain signal is converted into frequency domain signal through Fourier transform. Maximum enveloping method is used to analyse the features of transient pulse signal in frequency domain, and some anti-interference measures are given to improve the safety and reliability of railway signal equipment. |
