基于FFT的格雷母线定位算法研究

Research on Gray Bus Location Algorithm Based on FFT

格雷母线定位技术在工业上具有广泛的应用,但由于干扰源的多样性和多变性,系统的定位精度往往受到限制。为了提高系统的抗干扰性能和实时性,提出一种基于FFT(Fast Fourier Transform)的格雷母线定位算法,将母线上各通道信号的采样值转换到频域,提取有效频点的幅值和相位特征,进而计算位置。实验结果验证了所设计方法的可行性和有效性。

Gray bus location technology has broad application in the industry,but the positioning precision is limited due to the diversity and variability of interference sources.In order to improve the anti-interference performance and real-time performance,a new algorithm of gray bus location system based on FFT is designed in this paper.Transform the sampling values from the time domain to the frequency domain and extract amplitude and phase characteristics,and then position is calculated.Results show that the designed method is feasible and effective.
