The article considers the task of organizing the processing of rapidly changing parameters and monitoring the technical condition of on-board systems of combine harvesters, which is especially relevant in the conditions of restrictions imposed by its implementation in real time, that is, during the harvesting of grain crops by combine harvesters. The novelty of the methodology consists in justifying the order of selection of the evaluated characteristics of on-board systems, taking into account the satisfaction of the requirements regarding the completeness of the decision made under the conditions of time constraints. An example of a practical calculation of the application of the method is given and conclusions are drawn about the expediency of its application during the analysis of the technical condition of the on-board information-controlled systems of grain harvesters. Algorithmic complexity depends on the number of counts included in the window function, the width (duration) of the window function, and the step of the window function. Fast-changing parameters for wavelet transform and Fourier transform. The number of counts depends on the width of the window function and on the reading information from the on-board information-controlled system of the grain harvester. Thus, the algorithm for processing one characteristic was chosen.Further, choosing processing algorithms for the characteristics of the remaining fast-changing parameters in the same way, we obtain a set of ten characteristics of the fast-changing parameters, which are processed by the algorithms best in terms of efficiency, taking into account the requirements of the accuracy indicator. Many alternatives for solving the task are being formed. An alternative is one of the characteristics of fast-changing parameters, which can be processed by one of the methods using one of the window functions. Each window function, in turn, is characterized by its own characteristics, such as width, pitch and window type, which greatly increases the number of alternatives. Thus, the formed set of initial data allows you to take into account all the necessary methods of processing rapidly changing parameters in real time for choosing the best solution to the given task. Formation of a set of alternatives reduced by the accuracy index. At this step, the accuracy index is calculated for each alternative, after which we select those whose accuracy index is higher than or equal to the given one from the set of alternatives. Thus, the set of original data is reduced by the accuracy indicator.
