Real-time Acquisition and Processing of Measurement Information in the Complex Technical Systems Diagnosis

The article substantiates the expediency of using National Instruments (NI) hardware in technical diagnostics systems. The excessive volume of input measurement information and the need for its analysis in real time when conducting complex technical systems diagnostics leads to the need to use complex software and hardware complexes for input data acquisition and processing. It is possible to simplify the solution of the input data acquisition and analyzing problem by implementing irreversible compression of redundant measurement information using optimal hardware and software. To research the irreversible compression algorithms effectiveness, a simulation using the LabVIEW NI environment was carried out. Virtual instruments of irreversible data compression based on reconfigurable NI input-output modules (R-modules) have been investigated and developed using LabVIEW. The advantage of this approach is the use for the development of standard hardware based on an industrial or personal computer and R-modules programmed by LabVIEW.
