The necessary and sufficient requirements to functional, diagnostic, information, and other diagnostics and monitoring systems capabilities (SDM) are defined in GOST R 53563 and GOST R 53564 and the modern level of information-measuring equipment development provides an opportunity to collect and process the data synchronously and asynchronously through multiple channels with the reference to the shaft rotation angle in a given range of frequencies - from shares and units of Hz to several MHz.
It is advisable to use the power of computers and digital signal processors to calculate the diagnostic signs of malfunctions. However, the determining factor of the data-processing system development for piston machines monitoring management is the cost. In this case, as a rule, the main problem is to provide the system explosion safety.
Taking into account that the development rate of the malfunction is limited, based on the required period of measurement channels polling, the usage of series-parallel distributed system structure seems to be expedient for providing piston compressors condition monitoring. In such a system it is easier and cheaper to provide the explosion safety of the measuring circuits.
The most optimized from these points of view (the cost of one channel, explosion safety) is the COMPACS® automated system for safe resource-saving operation of equipment of refineries and petrochemical enterprises (SMSRTM™), realizing the SMСD™ - strategy of minimum cost diagnostics.
