Event e.g. corrosion leakage, detecting and locating system for fluid e.g. water, transport pipe, has analysis unit to analyze coherence of detection signals to confirm and localize impact, leakage or transient

摘要

The system has two deported detection modules, in which each module (10i) includes an acquisition unit (101) acquiring an acoustic time signal (20i) and a time stamping unit (102) time stamping the time signal. A transmitting unit (107) transmits a detection signal (23i) during detection of acoustic waves, vibrations or constraints relative to mechanical impact, leakage or pressure transient by a processing unit (103). A receiving unit (107') receives detection signals. An analysis unit (106) analyzes coherence of detection signals to confirm and localize the impact, leakage or transient. An independent claim is also included for a method for detecting and locating events in a fluid transport pipe.
