The use of the systems for monitoring the technical state of complex technological complexes, for example, trunk pipelines, allows increasing the depth and reliability of diagnostics, increasing the probability of detecting and preventing emergency failures. The article discusses the methodological aspects of such systems development, in particular the formation of their measurement base. It is noted that the quality of monitoring is influenced by the type, characteristics of methods and control devices, their number and configuration at the facility. The choice of measuring subsystems largely depends, on the one hand, on the specific conditions and monitoring objectives, and on the other hand – on the characteristics and properties of the sensors themselves. Determining the correct volume of measuring modules as part of monitoring systems is an iterative process of searching the optimal combination of three components: the number, locations and efficiency of measuring instruments operation. The article also describes the features of the numerical finite element method, since only its application provides building an adequate model of the object, the absence of which makes it impossible to form the lower measuring module of automated monitoring systems.
