基于灰色理论下有杆抽油系统故障判别的模型

Fault Discrimination Model of Sucker Rod Pumping Oil System Based on the Grey Theory

本文采用灰色理论与网格法相结合的方法,根据泵功图的特点,通过提取泵功图归一化灰度统计特征,以此构成分类特征向量,建立基于灰色关联理论的系统故障判别模型,可实现关于系统故障的计算机自动判别,进而判别某个泵功图数据是否属于泵内有气体的情况.

In this paper,the grey theory and grid method are combined,according to the characteristics of the pump power map,by extracting the pump dynamometer normalized grayscale statistical characteristics,thus constitutes the classification feature vector,based on the establishment of a system failure discriminator grey correlation theory model,enabling the automatic identification of computer system fault,and then determine whether a pump dynamometer data belong to the gas pump case.
