System and method for reconstructing and augmenting high frequency data

Abstract:

A method for augmenting low frequency rate data includes obtaining mechanical system operational data at a first and a second frequency rate, the first rate larger than the second rate, computing time intervals contained in the data, extracting respective samples of first and second frequency data, calculating individual cumulative values, resampling the first frequency rate data to simulate data at the second frequency rate, computing a multiplication factor, applying probabilistic model to the resampled first frequency data using the multiplication factor and rules, algorithms, and/or formulations, combining the resampled first frequency rate data with the second frequency rate data, analyzing the synthesized data set to determine if the mechanical system is viable to operate, and if the determination indicates an approaching end to the operational viability providing an indication to a control processor of the mechanical system. A system and non-transitory computer-readable medium are disclosed.
