The use of data analysis technologies for processing the temperature measurement results is aimed at solving the problems of controlling the parameters of controlling thermal modes, monitoring the thermal state of the main industrial equipment, as well as issues of integrity and availability of data circulating in automated control systems for technological processes.The article is devoted to the problem of determining non-stationary temperature fields in-side an object from the noisy results of surface temperature measurements and the parameters of external thermal effect on its surface. Mathematically, the heat transfer process is represent-ed by a parabolic equation, includes initial conditions, as well as boundary conditions formed from temperature measurements on the object’s surface and in accordance with the character-istics of the external thermal regime.
