METHOD AND DEVICE FOR EVALUATING AND PREDICTING A RESOURCE IN ACOUSTIC-EMISSION DIAGNOSTICS OF STRUCTURES Russian patent published in 2023 - IPC G01N29/14 

FIELD: structures acoustic emission diagnostics.

SUBSTANCE: invention is intended for resource estimation and forecasting in acoustic emission diagnostics of structures. The substance of the invention lies in the fact that a device for estimating and predicting a resource in acoustic emission diagnostics of structures, including acoustic emission transducers installed at the control points of a control object subjected to mechanical load, with the help of which elastic mechanical waves are converted into electrical signals that are fed to an analog - a digital converter, with which the output code is formed, then the informative parameters of the acoustic emission signals are calculated using the calculation blocks, the values of the informative parameters are recorded and evaluated using the information display device, while additionally including two calculation blocks, the inputs of which are connected to the analog output digital converter, and the outputs of these blocks are connected to the input of the block for combining the "convolution" of informative parameters, the first of which calculates the total number of acoustic emission pulses, and the second block determines the intensity of the flow acoustic emission pulses also additionally include a resource estimation and prediction block that estimates the structure resource, the input of this block is connected to the output of the block for combining the "convolution" of informative parameters, and the output is connected to an information display device.

EFFECT: increasing the reliability and reliability of determining the residual life of the structure.
