METROLOGICAL ANALYSIS OF THE MEASURING CHANNEL OF THE INFORMATION-MEASURING SYSTEM FOR DETERMINING THE ENVIRONMENTAL WELL-BEING OF HUMANS

Abstract

Background The basis for ensuring the ecological well-being of a person in the territorial technosphere is a multi-parameter analysis of the state of the elements of the territorial technosphere. The quality of the measurement control of risk factors determines the effectiveness of control actions aimed at ensuring the environmental well-being of a person. The purpose of this work is the metrological analysis of the measuring channel of a multichannel informationmeasuring system. To achieve this goal, it is necessary to solve the following tasks: to present the structure of the measuring channel; establish which components of the measuring channel affect the relative error of the measured value; calculate the relative error of the controlled parameter using its random and methodological errors. Materials and methods. The article presents block diagrams of the information-measuring system for ensuring the ecological well-being of a person and its measuring channel, considers the method for calculating the total relative measurement error, and shows dependencies for determining the relative error for each component of the measuring channel. Results. The calculation and analysis of the total relative error of the measuring channel for ammonia in the atmosphere were carried out, and the «contribution» of each component of the measuring channel was established. Conclusion. As a result of the metrological analysis of the measuring channel of the information-measuring system for determining the environmental well-being of a person, it was found that the total relative error is no more than 0,4 %, which is an acceptable value for measuring control.
