Інформаційні системи визначення дійсного значення фізичної величини при нестабільній функції перетворення

Abstract

The work demonstrates ways of increasing the accuracy of measurement information in information systems. Methods of redundant measurements are proposed to solve this problem. It is shown that due to the derived equation of redundant measurements gives a linear dependence of the measurement result on the value of the desired physical quantity. In addition, the processing of the results in accordance with the above equation ensures the independence of the measurement result from the parameters of the conversion function and their deviations from the nominal values. Based on the proposed mathematical model, a block diagram of the algorithm for measuring the desired physical quantity for the unstable transformation function is proposed.
