Abstract

Изобретение относится к способу мониторинга канала, переносящего текучую среду, который содержит опрос оптоволокна, расположенного вдоль пути упомянутого канала, для обеспечения распределенного акустического измерения; измерение посредством распределенного акустического измерения акустического сигнала на каждом из множества дискретных продольных измерительных участков вдоль длины оптоволокна, чтобы осуществлять мониторинг оптоволокна на наличие первого характеристического сигнала, причем первый характеристический сигнал указывает на вспучивание грунта в окрестности оптоволокна; и определение, что возникла неисправность в упомянутом канале, когда первый характеристический сигнал измеряется при распределенном акустическом измерении.
