| 摘 要： | 重大危险源在线监测数据的处理与分析,就是将原始信号进行适当的转换,形成特征明显且易于分析的新信号的一种科学,它是进行状态监测与事故预警的重要基础。本文对离散傅立叶变换和快速傅立叶变换进行了分析与比较,讨论了两种不同变换算法的优缺点和适用范围。实践应用表明,在在线监测系统中应采用快速傅立叶变换算法。

| Abstract: | Disposal and analysis of on-line monitoring data for major hazard is a science, which converts original signal to obvious character signal. It is the base of condition monitoring and accident pre-warning. Discrete Fourier transforms and fast Fourier transforms were analyzed and compared in this thesis. The advantage, disadvantage and applicability of discrete Fourier transforms and fast Fourier transforms were discussed. Application result shows that fast Fourier transforms should be adopted in on-line monitoring system. |
