摘要
波峰和波谷是波形上基本的局部形态特征基于波峰、波谷之间的支配关系,本文提出了一种规则波形的结构特征抽取与符号描述方法,进而建立了一个基于该方法的柴油机喷油压力波形结构模式分类系统,并通过实例验证了该系统的有效性。
An approach to feature extraction and symbolic representation of the fuel injection pressure waveform of diesel is proposed based on peak dominance relation between peak and trough in this paper. A waveform parsing system with application to structural pattern recognition of the pressure waveform based on the representation is described. The experiments have shown it is effective to the waveform recognition.
