Basic principles of diagnostics and monitoring of piston machines

In the basis of diagnostics and monitoring of piston machines lies collection and processing of the data providing detection of defects and malfunctions of piston machines with a set depth of specification and reliability, as well as the danger rates.

Diagnostics and monitoring technology realization is based on the structure models of vibro-acoustic signals occurring if case of failure nucleation in assemblies and details of piston machines, combination of their diagnostic features (DF) of malfunctions and signal parameters (DPF) if case of failure nucleation, standard values of DF and DPF, vibro-acoustic signal transduction and vibro-acoustic signal parameter assessment.

One practical method of the technology realization and diagnostic and piston machines monitoring problems solution is implementation of the mentioned above methodological decisions which determine the knowledge base connecting DPF and condition of assemblies and details of piston machines into the algorithms of the COMPACS^® diagnostic and monitoring system functioning.

The article deals with the principles of formation of the technology for diagnosing by vibroacoustic signal parameters and condition monitoring of piston machines. The methodology of diagnostic signal processing and the operating diagram of the system for technical diagnosing are considered. Particular attention has been paid to the structure and principle of operation of decision-making expert system.
