Abstract

Any technological system consists of devices interconnected by pipelines. Often, the length of pipelines is quite large. Checking their integrity is relevant and very costly in terms of time and human resources. It is not possible to create a real emergency situation at an existing production facility. It is possible to obtain information about the presence of a defect at an industrial facility only by simulating such a situation. For this, an experimental stand has been developed that allows monitoring the functioning of a closed air duct system of a simulated object. Situations are modeled under various external influences: when the dynamic characteristics of the working environment change; when various types of defects appear, etc. Functionally, the experimental stand was created as close as possible to real conditions. The developed stand opens up opportunities for practical experiments and direct obtaining of experimental data to identify defects in the air duct. To detect damage to the air circuit, integration of technical developments with the method of multiple signal classification (MUSIC) was performed.
