MICROWAVE PHOTONIC QUASIDISTRIBUTED ADDRESSABLE SENSOR SYSTEMS FOR MONITORING AND TECHNICAL DIAGNOSTICS OF POWER STATION PIPELINES

Abstract

The article presents the results of the development of methods for analyzing and principles for constructing microwave photonic quasidistributed addressable sensor systems for monitoring and technical diagnostics of power plant pipelines in order to improve their metrological and technical-economic characteristics using a new tool for implementing microwave photonic sensor technologies and multi-sensor multiplexing technologies – addressable fiber Bragg structures with wave and phase components. At the same time, the differences in the spectral characteristics of the components of the latter are taken into account when working on reflection and the possibility of their parallel paired connection both as a whole and by individual components when working on transmission. Microwave photonic sensor technologies using a new control tool are based, on the one hand, on the classical registration by individual structures the changes in the values ​​of longitudinal and transverse deformations of the pipeline caused by changes in pressure and temperature in the pipe, and on the other hand, on the possibility of forming an intelligent multi-sensor insert into the pipe in the pipeline support zone, which allows for additional monitoring of latter condition.
