System and method for calculating remaining useful time of objects
First Claim
1. A computer implemented method comprising:
- obtaining sensor data for a mechanical component;
determining a plurality of features based on the sensor data;
organizing the plurality of features into a defined matrix structure, the defined matrix structure including a plurality of columns, each column of the plurality of columns corresponding to a particular feature of the plurality of features, wherein the columns are sorted in the defined matrix structure in order of a strength of a monotonic relationship between the particular feature and time;
inputting data of the defined matrix structure into an artificial neural network; and
generating output identifying a remaining useful life of the mechanical component, the output based on a result generated by the artificial neural network responsive to the input data.

Abstract
An aspect of the present invention is to provide a system and method for predicting the remaining useful time of mechanical components such as bearings. Another aspect of the present invention is to provide a system and method for predicting the remaining useful time of bearings based on available condition monitoring data. Another aspect of the present invention is to provide a system and method for automatically deciding which columns of input information are the most significant for predicting the remaining useful life of bearings. Another aspect of the present invention is to provide a system and method for performing an analysis of both test bearings and training bearings and determining which training bearings are most similar to a given test bearing. Another aspect of the present invention is to provide a system and method for training an artificial neural network.
