Abstract

Рассмотрены базовые структуры микропроцессорных средств избыточных измерений температуры бесконтактными методами при разных видах нелинейной функции преобразования измерительного канала.

Показана возможность уменьшения влияния на результат измерений радиационной температуры коэффициента поглощения среды и излучательной способности объекта измерений. Работа представляет интерес для магистров, специалистов и ученых, интересующихся методами избыточных измерений температуры.

In paper base structures of microprocessor means of redundant measurements of temperature are considered by contactless methods at different kinds of nonlinear function of transformation of the measuring channel. All microprocessor means of redundant measurements of temperature contactless methods (digital pyrometers) represent informationredundant measuring systems. Definition of means of redundant measurements of temperature by contactless methods that allows to present their structure identical to measuring information systems is resulted. A variety of informationredundant measuring systems also defines existing variety of structures of digital pyrometers. It is shown, that the structure of digital pyrometers essentially depends on a kind of function of transformation of the opticelectronic channel, system of the mathematical models describing the realised method of redundant measurements, from degree of an openness, level of intellectualization and other factors. Structures with microconverters, the minimum number of remote terminal units, with linear opticelectronic channels and the block of memory of a database are optimum. The resulted structures of digital pyrometers differ from existing themes that provide the decision of metrological problems as realize methods of redundant measurements. Base structures of the digital pyrometers realizing methods of redundant measurements and corresponding systems of mathematical models, describing their work and processes of computing processing of results of intermediate measuring transformations of streams of optical radiation are resulted at linear, squarelaw, cubic, polynomial and logarithmic functions of transformation of the measuring channel. Work is of interest for masters, experts and scientists, the interested methods of redundant measurements of temperature.
