METHOD AND SYSTEM FOR MONITORING THE DEGREE OF WEAR OF METAL SURFACES Russian patent published in 2022 - IPC G01N27/20 G01B7/34 

FIELD: controlling.

SUBSTANCE: invention relates to means of monitoring industrial production processes; namely, discloses a method and system intended for estimating the degree of wear of a metal surface by measuring the AC electrical resistance in a broad frequency range. System for monitoring the degree of wear of metal surfaces comprises a memory apparatus and a microprocessor, interconnected; sensors made in the form of at least a pair of electrodes covering the surface of the monitored apparatus on at least one side; temperature sensors and an AC signal generator, electronically coupled with an integrated circuit, implemented whereon are software-coupled multiplexer, analogue-to-digital converter, microprocessor executing a signal filtering and averaging system, and a storage apparatus intended for storing the map of defects of the object of monitoring for comparing with impedance spectra by means of an algorithm executed by the microprocessor.

EFFECT: increase in the accuracy of determining the coordinates and size of defects and the dynamics of development of irregularities of metal surfaces for the purpose of prompt monitoring and planning of repair and preventive measures.
