SYSTEM FOR DETECTING AND LOCATING AN EVENT IN A FLUID CONVEYING PIPING HAVING A HORIZONTAL ARCHITECTURE

摘要

The invention relates to a method for detecting and locating an event [C] of the mechanical impact, leak or pressure transient type in a fluid conveying piping (1). The detection and location method of the invention includes at least two offset detection modules [10 i- 1,10i] connected between them by a communication network (12) and provided on the piping (1) so as to be separated from each other by predetermined distances [D i-1,i]. Each offset module [10 i] includes at least: acquisition means (101) for acquiring a time signal [20 i] from at least one acoustic wave of vibration or stress sensor [11 i] associated with the offset module [10 i] and referred thereto; timestamping means (102) for the time signal [20 i]; processing means (103) for the time signal [20 i] capable of detecting acoustic waves or vibrations or stresses indicative of a mechanical impact or a leak or a pressure transient; transmission (107) and reception (108) means capable of transmitting to the adjacent offset module(s) [10 i-1,10 i+1], and through the communication network (12), a detection signal [23 j] associated with the timestamp (22) of the time signal [20 i] corresponding to a detection, upon the inner detection by the processing means (103) of the offset module [10 i] of acoustic waves or vibrations or stresses indicative of a mechanical impact or a leak or a pressure transient, and capable of receiving from the adjacent offset module(s) [10 i-1,10 i+1], and through the communication network (12), one or more detection signals [23 j]; and confirmation and location means (106) capable of analysing the consistency of the detection signals in order to confirm and locate the mechanical impact or leak or pressure transient.
