Embodiment Construction

[0091] The concrete implementation of the present invention is described in detail below, it is necessary to point out here that the following implementation is only used for further description of the present invention, and can not be interpreted as limiting the protection scope of the present invention. Some non-essential improvements and adjustments still belong to the protection scope of the present invention.

[0092] Most of the existing related technologies separate each variable dimension of the fault data separately for calculation, but the present invention comprehensively considers the problems existing in the correlation information between different variables of the sample data, and realizes a bottom-up segmental fitting technology , taking into account the numerical characteristics of the fault data while extracting various overall morphological features of the fault data. Through this method, the present invention can realize effective compression of large-scale...

Abstract

An equipment fault diagnosis method successively comprises fault diagnosis training steps and fault diagnosis operation steps. The method focuses on a data form characteristic essence and combines a multi-dimensional segmentation fitting algorithm and an optimized dynamic time warping algorithm based on equipment fault data to carry out pattern expression of modeling and distance threshold extraction, and extract form characteristics from the found equipment abnormity data to carry out mode matching, so that an equipment data fault type can be identified and a reason diagnosis function is realized. In this way, the difficulties in current fault diagnosis technologies that similarity degrees among the fault data can hardly be described efficiently and accurately can be solved.

Description

technical field [0001] The invention relates to the technical field of fault diagnosis, in particular to a device fault diagnosis method. Background technique [0002] In recent years, with the continuous innovation and growth of science and technology and the rapid development of social industrialization, more and more industrial industrialization systems have been installed in large-scale industrial production occasions, creating irreplaceable huge productivity in this application environment . Therefore, the maintenance work of these equipments is particularly important and arduous. However, too many hidden influencing factors may cause the failure or even failure of these system equipment. Therefore, the state, enterprises and institutions are paying more and more attention to the status detection and fault diagnosis of these important system equipment. [0003] Generally speaking, the structure of these devices is becoming more and more complex and meticulous, and the...
