摘　　要：文章通过研究测量到的弓网电流数据,发现除了存在燃弧对它的干扰,还有噪声的影响,要想对数据有准确的研究,就要先对波形去噪。文章重点讲述了小波去噪方法,并且通过编写程序完成了对牵引电流的去噪,通过比较确定适合所测数据的参数,最终得到去噪后的波形。The article researches the measured data of the pantograph current,it is found that in addition to the interference of arcing,there is also the influence of noise,so if you want to have accurate of data for the research,first on the waveform denoising.The article focuses on the wavelet denoising method,and use the program completed the traction current denoising,then through the comparative analysis to determine the suitable for the parameters of the measured data,finally get the waveform after denoising.
