This paper describes three digital filtering methods for processing indicator diagrams of internal combustion engines based on the theory of digital signal processing to replace the commonly used diagram smoothing methods.

本文发展了二种基于数字信号处理理论的数字滤波法,用来对内燃机示功图进行处理以替代目前常用的“光顺”方法。根据用同态信号处理原理对发动机示功图及通道效应的频率特征进行的分析,本文得出了三种失真微小的频域数字滤波法:复合带阻滤波法(CBRF)、广义频率抽样滤波法(GFSF),逆滤波加选频滤波法(IARF)。这些基于示功图频谱分析的方法,具有简单的很容易确定的滤波器参数。为评定和改进数字滤波方法(本文用实验加数值仿真的闭环方法),在三台压燃式发动机上对上述方法进行了评定。结果证明滤波法能有效地把干扰与有用信号分离,并能将周期性强干扰从周期性信号中滤除。利用本文的方法,具有短测压通道的而不是平齐安装的传感器将可更精确地测量缸内压力,因为这时热冲击效应实际上可以忽略,而通道效应则可用数字滤波法滤除。此外本文还提出了三种示功图处理中的快速傅立叶变换(FFT)的预处理方法。

The basic theory of convolution homomorphic signal processing and method of its computer realization are discussed in this paper. The dada processing of the reverberative theoretical signals verifies that this method works well in distinguishing delayed signals. Seismic records of Luquan earthquake which occurred in Yunnan province on April 18,1985 are analysed,and the result is pretty good. Convolution homomorphic signal processing seems to be an effective method for distinguishing the delayed signals from...

Convolution homomorphic signal processing seems to be an effective method for distinguishing the delayed signals from the reverberant signal.

同态信号处理对于判别一个信号是否混叠有它的延迟信号,是一种有效的方法.文中首先讨论了同态信号处理的基本思想,及计算机实现同态信号处理的方法,用理论振波的多次延迟叠加进行了数值模拟的检验,结果表明能明显得到各延迟信号的延迟时间.最后,用此方法对1985年4月18日云南禄劝地震进行了同态信号处理,得到了满意的结果.
