Abstract
The development of new methods of technical diagnostics is an important task aimed at improving the efficiency and safety of the operation of industrial equipment. Such methods are complexes of jointly used methods for obtaining diagnostic information, methods for extracting from it the actual data on the technical state of the diagnosed objects, and methods for organizing diagnostic processes. Complex technical systems are characterized by complex nonlinear interactions between their constituent elements, complex scenarios of causal relationships between hazardous, probabilistic events and processes occurring during their operation. These scenarios can be implemented in complex scenario trees. Features of technical diagnostics of complex technical systems are determined by the distinctive properties of failures in such systems and scenarios. The technical diagnostics system is an information-measuring system and contains sensors of controlled parameters, communication lines with an information collection unit, executive devices, devices for interfacing with other information-measuring and control systems. Methods of technical diagnostics serve as the basis for constructing such a system. The current level and prospects for the development of diagnostic tools, flaw detection and automated control open real possibilities of using methods of maintenance and repair of equipment by a technical condition. The greatest effect from the use of such a system is achieved when operating complex equipment, preventive repair of which is associated with high costs, and emergency repair.
