Application of microprocessors for automation of diagnostics and technical condition control of tunneling machines
Incoming article date: 13.01.2023The method of automated diagnostics and control of the technical condition of the electric drive of mining machines, which consists in monitoring the current with subsequent spectral analysis of the received signal, is considered. It allows using the ATmega16 microcontroller to determine with sufficient accuracy the current technical state of the electric drive elements. The aim of the work is to prove the possibility and justify the effectiveness of the use of microprocessor technology in the mining industry to automate the diagnosis of machinery units. The adequacy of the developed methodology for determining the identification frequencies is confirmed by experimental data in the low-frequency region of the spectrum. The conclusion of this article is that a comparative analysis of the calculated and experimentally obtained amplitude-frequency characteristics of individual components of the drive motor and elements of the transmission of the executing body of the KP21 tunnelling machine has confirmed their adequacy.
