MULTICHANNEL FIBER-OPTIC CONVERTERS FOR MONITORING THRESHOLD VALUES OF PHYSICAL PARAMETERS OF PRODUCTS

The article is devoted to the development of multisensor fiber-optic converters for monitoring threshold values of physical parameters of industrial and social objects. The principles of interaction of the sensitive elements of the proposed converters with the objects of control using kinematic, magnetic and thermal effects are formulated. The designs of multisensor converters based on fiber-optic digital-to-analog converters with parallel and serial structural schemes are considered. Mathematical models of converters are proposed and algorithms for digital information processing in the electronic unit of converters are analyzed. A comparative analysis of the proposed converters and their analogs is given according to the criteria of energy efficiency, simplicity and availability of the electronic element base, as well as technical and economic indicators. It has been established that the proposed converters, depending on the type of fiber-optic digital-to-analog converter, provide information capacity at the level of 3…5 bits. The directions of development of the converters of the considered class, associated with the increase in their information capacity, are substantiated.
