摘要
针对当前机车故障诊断记录系统故障诊断能力提高和通用性扩展的需要,结合FFT算法特点,采用TMS320VC33实现快速傅立叶变换,使系统具备了频谱分析的能力,可以应用到谐波分析和振动分析等相关领域。
Aiming at the requirements of improving fault detection and expanding applicability in locomotive transient fault recorder, Fast Fourier Transform （FFT） is implemented in floating-point DSP TMS320VC33 based on FFT algorithms features, then the system acquires ability of spectrum analysis and can be applied in field of harmonics analysis and vibration analysis.
