The article considers analysis of existing methods and means for piston compressors monitoring and diagnostics. The peculiarities of the diagnostic and monitoring systems implementation have been presented, the piston compressors main units, which monitoring and diagnostics is of the main focus, have been listed. Architectures and operational principles of the known systems for the piston compressors monitoring and diagnostics have been considered.
Foreign stationary systems for on-line monitoring of the piston compressors parameters exercise control over these parameters, not determining the reasons for their changes, caused by specific malfunctions and their hazard rates.
Real-time systems for the equipment technical state monitoring, proposed and developed in Russia for more than 30 years, are deprived of these drawbacks. The fundamental difference between the real-time monitoring systems and the considered on-line monitoring systems lies in the integrated automated expert system for diagnosis-making, which automatically and in real-time points to the staff the degree of malfunctions development and their danger for the piston compressors and a technological unit, through a "thin" automatic analysis of signals.
