Trends in the Development of Metrological Self-Check and Automatic Technical Diagnostics

The analysis of the development trends in metrological self-checking/self-validation and automatic technical diagnostics has been carried out taking into consideration biological evolution. Characteristic features of these methods are compared. In the era of Industry 4.0, their future prospects are predetermined by the rapid growth of the variety of cyber-physical systems and broad dissemination of Internet of Things, which are characterised by the presence of redundant information links between system components. It is shown how this redundant information can be effectively applied. These patterns are illustrated by examples, including those from the authors’ experience. The necessity of international standardization in the considered field is shown.
