拖拉机发动机信号降噪与分离处理新方法

A New Method of Noise Reduction and Separation for Tractor Engine Signal

介绍了一种处理信号的新方法——模式滤波法,将该方法应用于拖拉机发动机信号的处理中,可实现信号与噪声合理、完整的分离,不仅为有效地去除发动机信号中的噪声奠定了基础,也为拖拉机发动机的故障诊断研究提供了理论参考。

A new method which is called the Pattern Filter Theory（PFT） was introduced in this paper.Applying it to process signal of tractor engine,signals and noises could be integrally and reasonably separated.The study provided the foundation to effective reduction of the tractor engine noises and theoretical reference to study on fault diagnosis of tractor engine.
