Intelligent fault diagnosis method and system for gas pressure regulating equipment, terminal and storage medium

Abstract

The invention provides an intelligent fault diagnosis method and system for gas pressure regulating equipment, a terminal and a storage medium. The method comprises the following steps: acquiring a gas pressure regulating equipment fault data feature vector of a known fault type, training an SVM algorithm by using a training sample as the training sample of the SVM, and establishing an SVM fault diagnosis classification model by using a Gaussian radial basis kernel function K; optimizing the parameters C and g of the SVM fault diagnosis classification model by adopting a genetic algorithm, andestablishing an optimized SVM fault diagnosis classification model; and utilizing the optimized SVM fault diagnosis classification model to carry out fault diagnosis on the gas pressure regulator toobtain a fault type. The classification model based on the support vector machine is constructed, the fault type is diagnosed, the problems that in the prior art, fault data are few, and high-precision recognition cannot be carried out on the fault type are solved, good learning ability is achieved, and the problems of data small sample, non-linearity, high-dimension classification and the like can be solved. Finally, an implementation scheme of the computer system is provided.

Description
