Promising directions for increasing reliability radio-electronic equipment based on physical diagnostics using information technologies

Abstract

In modern economic conditions, the renewal of the fleet of radio-electronic equipment is carried out relatively slowly. The subsequent operation of complex objects of high-cost radio-electronic equipment with a standard operating life of 25-30 years becomes possible with the availability of high-quality diagnostic, metrological and information support, the use of which will allow to determine the technical condition of objects with high reliability and to predict the residual life. Known methods for diagnosing typical replacement elements as components of electronic equipment blocks are based on comparing output reactions with reference ones, which makes it possible to determine their technical condition at the moment. This also causes the difficulty of performing the third function of technical diagnostics - forecasting the residual resource. These reasons lead to the development of diagnostic methods that will allow determining the technical condition of typical replacement elements, as well as making predictions with high reliability, which, in turn, dictated the need for forced testing of typical elements for reliability. The result of such tests was to obtain the dependencies of diagnostic parameters on the operating time, the comparison of which with those obtained during routine maintenance will allow solving the above problems. To improve the reliability of the diagnosis, it is proposed to combine diagnostic methods. The article presents an overview of the possibilities of diagnostic support, mathematical models of physical diagnostics and forecasting of the technical condition, identifies the directions for further research and substantiates the feasibility of developing new solutions to improve the reliability of radio-electronic equipment.
