Однако в этих системах при изменении технологических параметров шаг дискретизации анализируемых сигналов не меняется несмотря на необходимость такой процедуры. Из-за этого на практике имеют место случаи, когда не обеспечивается адекватность результатов решаемых задач. На железнодорожном транспорте в подвижных составах применяются системы контроля и диагностики, которые диагностируют неисправности в колесно-моторных блоках, дефекты подшипников, отсутствие и недостаток смазки, перекосы установки подшипника, дефекты крепления, нарушение баланса вращающихся частей, дефекты редуктора. Также диагностируются неплотности питательной и тормозной магистралей, неисправности крана машиниста, неисправности тормозных цилиндров, неисправности компрессора. Результаты контроля прежде всего отражаются на мониторе машиниста. В этих системах из-за задержки результата контроля иногда принятие соответствующих мер оказывается запоздалым. Например, из-за специфики железнодорожного транспорта при анализе вибрационных сигналов, получаемых от одних и тех же датчиков, результаты контроля при изменении скорости поезда меняются. Из-за этого возникает дополнительная погрешность, что часто становится причиной нарушения адекватности результатов контроля. Для устранения этого недостатка, в первую очередь, необходимо при изменении скорости подвижного состава пропорционально изменить шаг дискретизации анализируемых сигналов. При вибрационной диагностике адекватность полученных результатов в значительной степени зависит от точности определения шага дискретизации. Показано, что технология и принцип построения аналого-цифровых преобразователей с адаптивным определением шага дискретизации путем учета динамики функционирования контролируемых объектов позволяет избежать погрешности контроля, вызванной ошибкой выбора шага дискретизации.</p></abstract><trans-abstract xml:lang="en"><p>It is shown that in order to ensure accident-free operation of production facilities it is necessary to increase the degree of adequacy of the results of the analysis of technological parameters in control and diagnostic systems. However, in these systems, when changing the dynamics of technological parameters, the sampling interval of analyzed signals does not change despite the need for such a procedure. Because of this in practice there are cases when the adequacy of the results of solved problems is not ensured. In rail transport, control and diagnostic systems are used for rolling stock, that diagnose malfunctions in wheel-motor units, bearing defects, lack and insufficiency of lubrication, misalignments of bearing mounting, defects of fastening, imbalance of rotating parts, defects of gearbox. Also diagnosed are looseness of the feed and brake lines, malfunctions of the brake valve, malfunctions of the brake cylinders, malfunctions of the compressor. The inspection results are first of all displayed on the driver’s monitor. In these systems, due to the delay in the monitoring result, sometimes the appropriate measures are delayed. For example, due to the specifics of rail transport, when analyzing the vibration signals received from the same sensors, the control results change when the train speed changes. This causes additional error, which can often lead to the violation of the adequacy of the control results. To eliminate this shortcoming, first of all, it is necessary to proportionally change the sampling interval of the analyzed signals when changing the speed of the rolling stock. In vibration diagnostics, the adequacy of the obtained results depends to a great extent on the accurate determination of the sampling interval. It is shown that the technology and principle of construction of analog-to-digital converters with adaptive determination of the sampling interval by taking into account the dynamics of the operation of controlled objects allows to avoid the control error caused by the error of sampling interval selection.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>аналоговый сигнал</kwd><kwd>дискретизация</kwd><kwd>преобразователь</kwd><kwd>вибрация</kwd><kwd>контроль</kwd><kwd>диагностика</kwd><kwd>транспорт</kwd><kwd>неисправность</kwd><kwd>железные дороги</kwd><kwd>датчики</kwd></kwd-group><kwd-group xml:lang="en"><kwd>analog signal</kwd><kwd>sampling</kwd><kwd>converter</kwd><kwd>vibration</kwd><kwd>control</kwd><kwd>diagnostics</kwd><kwd>transport</kwd><kwd>malfunction</kwd><kwd>railroads</kwd><kwd>sensors</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Aliev T.
