Abstract

L’invention concerne un procédé (100) de détection d’incident dans un véhicule de transport en commun, en particulier dans un véhicule ferroviaire, comprenant au moins une itération d’une phase (102), dite de détection, comprenant au moins les étapes suivantes : captation (104) dans ledit véhicule de transport en commun, et en particulier dans une zone passager dudit véhicule de transport en commun, d’au moins un flux audio, dit premier flux audio, par au moins un dispositif, dit portable, ledit dispositif comprenant au moins un moyen de captation audio et étant prévu pour être porté par une personne évoluant au sein dudit véhicule de transport en commun, transmission (106) dudit au moins un premier flux audio capté à au moins un dispositif, dit d’analyse, distinct dudit au moins un dispositif portable et comprenant au moins une unité de calcul intelligente, et analyse (108), par ladite au moins une unité de calcul intelligente, dudit au moins un premier flux audio pour détecter un incident. Elle concerne également un système de détection d’incident pour la mise en œuvre d’un procédé selon l’invention ainsi qu’un véhicule de transport en commun équipé d’un tel système de détection d’incident. Figure : Fig. 1The invention relates to a method (100) for detecting an incident in a public transport vehicle, in particular in a railway vehicle, comprising at least one iteration of a phase (102), called detection, comprising at least the following steps: capture (104) in said public transport vehicle, and in particular in a passenger area of said public transport vehicle, of at least one audio stream, called first audio stream, by at least one device, called portable , said device comprising at least one audio capture means and being intended to be worn by a person moving within said public transport vehicle, transmission (106) of said at least one first audio stream captured to at least one device, called d analysis, distinct from said at least one portable device and comprising at least one intelligent calculation unit, and analysis (108), by said at least one intelligent calculation unit, of said at least one first audio stream to detect an incident. It also relates to an incident detection system for implementing a method according to the invention as well as a public transport vehicle equipped with such an incident detection system.
