The number of unscheduled repairs (and consequently operating costs) can be considerably reduced by the implementation of diagnostic systems at factories and depots (in order to evaluate the quality of manufacture and repair of particular assemblies and overall electric multiple unit) and real-time condition monitoring systems for the most important assemblies of electric multiple unit in the field.
Diagnostic stations built on the basis of the COMPACS®-EXPRESS monitoring systems of vibration analysis are extensively used in repair of wheel motor units (WMU) at depots and factories of the country.
COMPACS®-EXPRESS-TR3 is the system for electric multiple unit comprehensive diagnostics after TR3 repair.
The COMPACS®-EXPRESS on-board system is designed for condition monitoring of WMU and bearing boxes of electric multiple units in the course of motion in actual operating conditions. The system concerned enables timely detection of defects emergence or development by displaying them on the screen in the driver's cabin.

Safe operation of complicated productions including hundreds and thousands of units of energy equipment is only possible with the information on its technical condition and available power being submitted to the company administration.
Automated Control Systems of Safe Resource-saving operation and Maintenance of equipment (ACS SRSM™) represent a new class of production control systems that inseparably link all stages of diagnosing.
ACS SRSM™ realize a safe resource-saving technology (Safe Maintenance™ - SM™ - technology) for equipment condition control, which enables real-time condition monitoring of equipment and controllability of its quality at all stages of life cycle, stability, safety and efficiency of production process.

The paper presents the results of theoretical and experimental investigations intended to justification of choice of the complex of diagnostic signals and features for evaluation and prediction of technical condition of rotor machines and units.
In the practice of vibration analysis and vibration control sometimes the signals of vibration acceleration and vibration displacement are not put to use because they are considered to be closely coupled with vibration velocity signal. In the course of repeated observation of vibration parameter trends accumulated by the systems for vibration analysis and vibration monitoring at a number of Russian plants more than once we evidenced the cases when only parameters of vibration acceleration and/or vibration displacement responded to the development of various defects of rotor assemblies.
These cases denote considerable narrowing of the range of diagnosed malfunctions with the use of parameters of only vibration velocity signal. Thus, the problem of independence degree of the signals of vibration acceleration, vibration velocity and vibration displacement arises.

Improving the quality and reliability of aviation equipment is impossible without correct information on its technical condition at all stages of equipment life cycle. Information on present, past and future technical condition of a product is obtained by the methods of technical diagnosis, genesis and prediction.
Regularities of machinery performance loss revealed during long industrial researches of thousands of machines and units in the field enabled to formulate a number of principles of the synthesis of continuous monitoring systems and Automated Control Systems of Safe Resource-saving operation and Maintenance of equipment (ACS SRSM™).
Realization of these and other principles enabled creation of new methods of diagnostics and prediction of the machinery service life without dismantling, which are invariant to equipment construction and form of connection between diagnostic features and structural parameters of technical condition applied in the COMPACS® systems and software.

We examined the principle of a spectral matrix which is based on the method of vibroacoustic diagnostics of batch-type equipment using synchronous comb filtering.
Modern computer aids enable realization of this method in the frequency domain, which increases precision of selection of multiple frequency components, and improves operation speed by ensuring the potentiality of work at the samples with limited length.
On the basis of the algorithms of a spectral matrix we developed the COMPACS® expert system that enables reasonably quick, complete and reliable diagnostics of technical condition without equipment dismantling.

Automated Control Systems of Safe Resource-saving operation and Maintenance of equipment (ACS SRSM™) enable automatic acquisition and use of reliable diagnostic information on the equipment condition in real-time mode. Such information represents a complex of diagnoses of condition of structures, machines, units and mechanisms that are collected on closely adjacent intervals of time so that the equipment condition varies insignificantly.
Nowadays about ten kinds of nondestructive testing (such as vibration, acoustic emission, thermal, electrical, etc.) are integrated in ACS SRSM™ COMPACS®.
Thus, the system enables continuous monitoring of production complex by the set of different methods of nondestructive testing on the basis of integrated hardware and software platform (COMPACS® distributed system for vibration analysis and computer monitoring), which enables diagnosing of condition of machine and columned-capacitive equipment, pipelines and tanks, furnaces and other equipment of petrochemical complex.
