FIELD: measuring.

SUBSTANCE: invention relates to gas mass concentration measurement means. Process parameters are continuously measured by means of an automated process control system. Measured parameters are transmitted in digital form to a unit for calculating emissions, where functional dependence of the measured value on auxiliary values of input parameters is determined. Said dependence is a predetermined transformation function with constant offset coefficients. Obtained conversion function is stored in the computer memory unit. Signals from the emission calculation unit are sent to the measurement accuracy control device. Signals containing information on the measured value of the mass concentration of the gas are sent from the series formation unit to the space-time field formation unit, where using the function of conversion into controlled time intervals, the measured value is estimated from the found functional dependence of the measured value on auxiliary values obtained based on measurement of process parameters affecting the formation of structural functions. Structural functions in a space-time field are obtained in the form of a tensor field of time series data, for which two independent spaces of two measurement systems are determined, vector space of target parameter and space of time, which is a complex unit sphere. Transmitting a signal containing information on the evaluation of the measured value from the space-time field formation unit to the Kolmogorov structural function unit, where the source of random components is selected from the measured value with subsequent division into errors in measurement and errors associated with the technological process. Further, the obtained information in the form of digital signals is transmitted to a kriging regression unit and interpolation estimates based on Gaussian processes are determined. Configuration containing information on the dynamics of the technological process of the measured value is read from the state space unit of the control object into the Kalman observer unit. Transmitting from the kriging regression unit a signal containing information on interpolation estimates to the Kalman observer unit, where the process is divided into components determined by the dynamics of the process of the measured value in the form of a parametric model of the technological process described in the state space unit of the control object. Signals containing information on components associated with measurement errors of the measured value and the process are transmitted to a unit for calculating true values. In the unit for detecting true values, the measured true values of the value at said moments in time are detected using the unit for calculating true values. Information on the true values of the value at the specified moments of time is stored in the unit for storing values, the results of transformations over the data are stored in the memory unit of the computer. Values of true instantaneous values of the measured quantity are calculated from the difference of the found components from the measured values of the mass concentration of gases. Measurement accuracy estimates are calculated by determining, in random components, average values and mean-square deviation of the data series. Obtained information on the measured calculated true values of the quantity and their accuracy estimates for the required moments in time are transmitted to the information output unit.

EFFECT: high accuracy of measuring concentration of pollutant emissions in real time at an industrial enterprise.
