Abstract

The invention belongs to the technical field of weapon equipment fault prediction, and relates to a fault prediction method based on big data, an abnormal data set is determined by comparing a data set in a normal state with a data set in an abnormal state, however, the abnormal data set is very large in data size and cannot obviously reflect data abnormity, and therefore the abnormal data set cannot obviously reflect data abnormity. According to the method, the sensing data are converted into abnormal data features, the corresponding relation between the abnormal data features and the fault events is found through the fault prediction model, the complex relation between the sensing data does not need to be analyzed, and the fault prediction model aims at the whole complex system, so that compared with a method for predicting faults through a single model, the method has more accurate prediction precision.

Description

technical field [0001] The invention relates to the technical field of failure prediction of weapon equipment, in particular to a failure prediction method based on big data. Background technique [0002] With the development of science, technology and industry, machinery and equipment are developing towards large-scale, high-speed and complex. Therefore, current weapons and equipment are usually composed of many components, with many structural levels, complex relationships between different components, and strong coupling. Once the weapon equipment system fails, it often endangers the life of the personnel. [0003] Therefore, in order to improve the reliability and safety of the weapon equipment system, it is necessary to carry out the failure prediction of the equipment, monitor the status data of the weapon equipment at any time, so as to predict the failures that will occur. [0004] Existing fault estimation methods based on principal component analysis have been su...
