Abstract

 

The purpose of this paper is to increase the efficiency of determining the technical condition of complex electronic devices by recording and analyzing electromagnetic fields induced by signal emissions from elements of their printed topology. We used experimental research methods to receive and record the electrical component of the electromagnetic field emitted by the product - a signal radio profile (SRP). The results showed the possibility of detecting a malfunction when analyzing the correlation function between the benchmark and the adopted SRP, which determines the novelty of the work. It has been established that when the correlation coefficient between the studied SRP and the reference point is less than 0.9, the fault can be not only detected, but also localized. Using the example of an element of the Smart Home system - a heating controller with intentionally introduced faults into its relay control unit, the possibility of identifying and localizing a fault at an early stage of its occurrence is shown. The practical significance of the paper lies in the possibility of determining a malfunction using the radiosensor diagnostics (RSD) method at an early stage, which is not available to other methods for determining the technical condition.
