本课题研究内容：在不要点，不开天窗，不中断行车，不中断被测区段牵引电流的情况下，在线、动态、实时测量电化区段和非电化区段的移频信号电压、工频干扰电压，移频信号（调频信号）的上边频、下边频、载波频率、以及低频18信息频率等参数。 | | 5. | Since the energy of 18 - information track signal is concentrated around upper frequency and lower frequency , the frequency of the modulation signal is low , and it must have high resolution , we use zfft to detect it . as the energy of um - 71 signal is more concentrated , we use extreme value method to detect the frequency of modulation signal in frequency domain , which can satisfy the frequency resolution
针对18信息轨道信号能量集中在上、下边频附近且低频信息频率低的情况,提出了用zoom - fft ( zoom指频率扩展或细化,简称zfft )算法进行信号的局部放大检测低频信息,以提高信号的频率分辨率,而um - 71轨道信号能量集中在载频附近,在频域上采用极值法检测低频信息,即可满足信号频率分辨率的要求。 |
