A Cyber-Physical System for Monitoring the Technical Condition of Heat Networks

Abstract

Issues of creating a new generation of heat pipe monitoring systems using the method of pulse reflectometry are considered. The control conductors built into the thermal insulation layer along the thermal conductor ensure the detection and localization of an ongoing or forecast accident during the thermal insulation dampening. The introduction of technological innovations in the primary basic structure has led to a reduction in equipment and an increase in system reliability. New hardware and software tools have created the conditions for in-depth analysis of the technical condition of heating networks and solving new control tasks. The proposed approach and its development correspond to the concept of cyber-physical systems. The physical process of wetting insulation is an indirect but significant accident factor. Control of wetting in the prescribed tolerances fixes a sign of an accident when going beyond the tolerance field. However, the value of the parameters of a pulse reflected from the place of moistening, the dynamics of its changes contain important additional information for a possible forecast of the technical condition and energy efficiency of pipelines and heat networks in general. The formation, transmission, processing of information from many objects of heat networks using knowledge bases, the Internet of Things and other elements of the Industry 4.0 concept ensures the generation of near-optimal solutions and the achievement of high energy efficiency.
