Рассмотрены существующие статистические и логистические системы, позволяющие обрабатывать диагностическую информацию при оценке технического состояния трубопроводов. Современные методы диагностики в основном основаны на использовании вибрационных, звуковых и ультразвуковых датчиков. Наличие дефекта в трубопроводе определяется путем анализа амплитуды диагностического сигнала. Более высокую эффективность при обнаружении дефектов показали вероятностно-статистические методы анализа сигналов, основанные на теории хаоса. Одним из таких методов является энтропийный анализ. Анализ современных методов обработки сигналов показал, что наиболее эффективными являются методы, основанные на теории хаоса. Рассмотрена возможность использования энтропийных показателей в качестве чувствительных диагностических признаков. Проведен сравнительный анализ обработки сигналов с использованием энтропийных методов (энтропия Шеннона, энтропия Колмогорова) и известных статистических и логистических методов (преобразование Фурье, вейвлет-преобразование, преобразование Гильберта-Хуанга). Результаты анализа показали, что энтропийные показатели реагируют на изменение структуры сигнала, вызванное наличием дефекта в трубопроводе или Энтропийный анализ является перспективным методом обработки диагностических сигналов при оценке технического состояния трубопроводов.</p></abstract><trans-abstract xml:lang="en"><p>The purpose of this article is to review the existing reliability problems of pipeline systems of power complexes. The article considers the existing statistical and logistics systems, which allow to process diagnostic information when assessing the technical condition of pipelines. Modern diagnostic methods are mainly based on the use of vibration, sound, and ultrasonic sensors. The presence of a defect in a pipeline is determined by analysis of the amplitude of a diagnostic signal. Higher efficiency in detecting defects was shown by probability-statistical methods of signal analysis, which are based on chaos theory. One such method is entropy analysis. Analysis of modern signal processing methods has shown that methods based on chaos theory are the most effective. The possibility of using entropy indices as sensitive diagnostic signs is considered. Comparative analysis of signal processing was carried out using entropy methods (Shannon entropy, Kolmogorov entropy) and using known statistical and logistic methods (Fourier Transform, Wavelet Transform, Hilbert-Huang Transform). The analysis results showed that entropy indicators respond to a change in signal structure caused by the presence of a defect in the pipeline or Entropy analysis is a promising method of processing diagnostic signals when assessing the technical condition of pipelines.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Анализ</kwd><kwd>применение</kwd><kwd>энтропийные методы</kwd><kwd>обработка</kwd><kwd>вибродиагностические сигналы</kwd><kwd>оценка</kwd><kwd>техническое состояние</kwd><kwd>трубопроводы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Analysis</kwd><kwd>application</kwd><kwd>entropy methods</kwd><kwd>processing</kwd><kwd>vibrodiagnostic signals</kwd><kwd>evaluation</kwd><kwd>technical condition</kwd><kwd>pipelines</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">Gaponenko S.O., Kondratiev A.E.
