RBF fault diagnosis method and system based on PCA data processing, terminal and computer storage medium

Abstract

The invention provides a gas pressure regulator intelligent RBF fault diagnosis method and system based on PCA data processing, a terminal and a computer storage medium. The method comprises the stepsof acquiring original fault data of a gas pressure regulator with a known fault type; carrying out dimension reduction processing on the original fault data by adopting a principal component analysismethod to generate low-dimension irrelevant sample data; and performing fault classification on the sample data subjected to dimension reduction processing by the principal component analysis methodby using a radial basis function neural network. According to the invention, the original fault sample data of the gas pressure regulator is preprocessed by using the principal component analysis method, and the new sample data after dimension reduction processing is taken as the input of the radial basis function neural network, so that the dependence on experience is effectively reduced, the uncertainty caused by artificial participation is reduced, the fault early warning and intelligent fault diagnosis of main vulnerable parts of the pressure regulator can be realized, and an important role is played in the stable, safe and reliable operation of gas equipment.

Description

technical field [0001] The present application relates to the technical field of fault diagnosis of gas pressure regulators, in particular to an intelligent RBF fault diagnosis method, system, terminal and computer storage medium for gas pressure regulators based on PCA data processing. Background technique [0002] The gas supply system can be described as the lifeline project of the city, and it plays an indispensable role in economic development and social security and stability. With the continuous development of the city, the scale of the city's gas supply system is also gradually expanding, and its stability and safety issues are increasingly prominent in the daily operation process. Through searching for information and field investigations, we know that natural gas pipeline transmission and distribution systems usually include gate stations, storage and distribution stations, transmission and distribution pipeline networks, surge rooms, operation management operation...
