THEORETIC NUMBER BASIC METHODS OF INFORMATION TECHNOLOGIES FOR DIAGNOSTATION OF TECHNOLOGICAL OBJECTS OF THE OIL & GAS INDUSTRY

Abstract

. The existing methods of formation and coding of technological data at the grass-roots levels of distributed computerized systems for diagnosing technological objects in the oil and gas industry are analyzed. Methods of processing signals are analyzed. The mathematical model of multibase spectral cosine signal transformation, with the possibility of using different theorems of numerical bases, is considered. Correlation analysis of signals can be performed on the basis of different automobile and inter-correlation functions, but the highest speed and the smallest hardware complexity are characterized by functions in the theory of the Haar numerical basis. Where it is evident that in practice the widest use has been found in the form of information converters based on an analog digital converter of various types. The research of analog digital converters has been carried out on hardware complexity as well as on time complexity. The research was carried out on single-channel analogue digital converters with source codes, the theorem of the numerical basis of Haar, Krestinson, Rademacher and unitary basis. The paper deals with the development of digital correlators and transducers where among many structures of analog digital converters the most commonly used with source codes in different theorems of numerical bases and methods of formation of source codes are identified. The structure of the analog digital converter is proposed for the use of comparators with paraphase outputs and the implementation of a logical element that excludes OR on logical elements of I-NE with paraphase inputs and are connected by inverted outputs. Thus, the proposed improvement of the structure allows to increase its speed and reduce the time complexity of transformations by 2.5 -3 times. This reduces hardware complexity by about 30%. The method and structures of the transformation of the input analog signal by the multi-base ADA of Haar-Krestenson using the comparators with paraphase outputs in discrete digital samples for diagnostics of technological objects in the oil and gas industry and further calculation in computer technology are developed.
