FUNDAMENTALS OF SYSTEMATIC DIAGNOSTICS OF MACHINES

The paper reveals a systematic approach to the diagnostics of technical objects using modern methods and means. Two authors consider two of the three diagnosing levels as elements of the unified concept called systematic diagnostics. The first level includes examination of so called organoleptic indicators of the object and its functioning. Such indicators only have high significance for experts, so to interpret them the authors suggest applying the Exsys ex-pert evaluation system, which is a software and hardware package together with its databases. The expert system elaborated by the authors can trace a defect by its symptoms, and gives a list of probable causes of defects in a descending probability level. The more complete information capability is enhanced by applying instrumental (indicator and in-depth ones) diagnostics methods. The use of complex methods in the framework of system diagnostics is a very urgent task of increasing the reliability and durability of automotive and combine diesel engines by controlling their technical condition during their operation and one of the main technologies of resource-saving farming technology.
