Event e.g. corrosion leakage, detecting and locating system for e.g. water, transporting pipe, has detection module with transmitting unit with descriptor part associated to time signal timestamp and transmitting detection signal

摘要

#CMT# #/CMT# The system has two deported detection modules, each module (10i) includes an acquisition unit (101) acquiring an acoustic time signal (20i) and a transmitting unit (107) transmitting a detection signal (23i). A processing unit (103) of the module processes the time signal to calculate a multi-component descriptor (21i). The transmitting unit has a part of the descriptor associated to the time signal timestamp (22) corresponding to the detection towards the adjacent module or towards an analyzing device that analyzes the detection signal to confirm and to locate an event. #CMT# : #/CMT# An independent claim is also included for a method for detecting and locating an event. #CMT#USE : #/CMT# System for detecting and locating an event e.g. mechanical impact relative to proximity work or to passage of inspection tools, leakage e.g. corrosion leakage or accidental leakage, and pressure transient caused during opening/closing of valves, unauthorized closing or occurrence/cessation of leakage due to rupture of a pipe that transports fluid e.g. water, hydrocarbon oil or gaseous petroleum. #CMT#ADVANTAGE : #/CMT# The configuration of the system permits the utilization of communication networks of low transport rate and low band-width, in a simple and inexpensive manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic block diagram of a deported detection module of an event detecting and locating system. 10i : Deported detection module 20i : Acoustic time signal 21i : Multi-component descriptor 22 : Time signal timestamp 23i : Detection signal 101 : Acquisition unit 102 : Timestamping unit 103 : Processing unit 107 : Transmitting unit.
