В настоящее время число неожиданных аварий в значительной степени зависит от квалификации персонала, который на основе накопленного опыта и полученной информации от систем контроля интуитивно определяет текущее техническое состояние объекта и начало возможных аварий. Иногда их решение оказывается запоздалым, и происходят аварии в результате возникновения и развития различных неисправностей. В это время объекты переходят в скрытой период аварийного состояния, появляются помехи, коррелированные с контролируемым сигналом. При этом в зависимости от характера неисправности изменяется динамика протекания технологических процессов, под влияниям чего также изменяются спектры полезных сигналов и помехи. Согласно традиционном технологиям помехи фильтрируются. Из-за этого вносится дополнительная погрешность в результат анализа сигналов, и теряется важная диагностическая информация. Для решения задач контроля начала скрытого периода аварий в качестве информативного признака предлагается использовать оценку взаимнокорреляционной функции между полезным сигналом и помехой с применением технологии адаптивной дискретизации анализируемых сигналов. Для обеспечения адекватности результатов контроля формируется информация о начале скрытого периода аварий, которая позволяет мастеру определить время начала скрытого периода аварий с достаточной надежностью.

Nowadays the number of unexpected accidents depends to a great extent on the qualification of the personnel, who on the basis of the accumulated experience and the information received from the control systems intuitively determine the current technical condition of the object and the beginning of possible accidents. Sometimes their decision is too late and accidents occur. Usually, accidents occur as a result of occurrence and development of various malfunctions and at this time objects go into the latent period of emergency state, there noise emerges, correlated with the signal g(t) under control. Here, depending on the nature of the malfunction the dynamics of technological processes changes, under the influence of which, the spectra of useful signals X(t) and noise ε(t), g(t) = X(t) + ε(t) also change. When using the traditional technology, the noise is filtered. This introduces an additional error in the result of signal analysis, leading to a loss of important diagnostic information. To solve the problems of control of the beginning of the latent period of accidents it is proposed to use the estimate of the cross-correlation function between the useful signal and the noise as an informative attribute, using the technology of adaptive sampling of the analyzed signals g(t). To ensure the adequacy of the results of control by combining the proposed and traditional technologies information is formed about the beginning of the latent period of accidents, which allows the master to determine the time of the beginning of the latent period of accidents with sufficient reliability.
