摘要	The invention relates to a detection and localization system for an event [C] of the mechanical impact, leak or pressure transient type in a fluid transport channel. The detection and location system according to the invention comprises at least two detection offset modules [10 i-1 ,10 i ] to be mounted on the channel [1] and separated one from the other by known distances [D i-1,i ]. Each offset module [1O i ] is capable of calculating [104] a descriptor [21 i ] comprising N levels originating from the spectral density of the time signal [20], detected and time dated in N frequency bands describing the occurence of the event and to analyze [105] these levels [Niv] and to emit a part of the descriptor [21 i ] to at least one adjacent offset module [10 i-1 ] or to an analyzing device [13] capable of analyzing the detection signals [23 i ], to confirm and localize the mechanical impacts or transient or leaks.
