Description
SYSTEME DE SURVEILLANCE ET D'INFORMATION D'UNITES DE MONITORING AND INFORMATION SYSTEM OF
TRANSPORT EN COMMUNPUBLIC TRANSPORT
L'invention concerne, dans les transports en commun, un système pour surveiller l'espace de chaque unité de transport en commun et pour informer les passagers sur un certain nombre de sujets d'intérêts. Les unités de transport en commun telles que les bus et les wagons de train sont parfois le siège d'actes de vandalisme ou de violence dont on cherche à réduire le nombre par une meilleure connaissance des circonstances de ces actes et une meilleure information des passagers en ce qui concerne notamment le trajet en cours.The invention relates to a system in public transport for monitoring the space of each public transport unit and for informing passengers on a number of subjects of interest. Public transport units such as buses and train cars are sometimes the site of acts of vandalism or violence, the number of which is sought to be reduced by better knowledge of the circumstances of these acts and better information for passengers. especially concerning the current journey.
Pour connaître les circonstances d'actes de vandalisme et/ou de violence, il est prévu d'utiliser des caméras de télévision dites caméras vidéo qui enregistrent en continu des scènes se déroulant dans un certain espace de l'unité de transport en commun sur un support d'enregistrement tel qu'une bande magnétique en forme de cassette ou un disque magnétique dont le contenu peut être extrait sous la forme d'une cassette amovible. Lors de la survenance des actes de vandalisme et/ou violence, le machiniste de l'unité de transport déclenche, pour la caméra et son support d'enregistrement, un processus par lequel la caméra continue à filmer la scène et à l'enregistrer pendant un temps déterminé, par exemple dix minutes, à arrêter cet enregistrement à l'expiration de ces dix minutes, de sorte que le support d'enregistrement contient, par exemple, vingt minutes d'enregistrement ou plus selon la taille de la cassette, couvrant 10 minutes ou plus avant la survenance des actes et les 10 minutes suivantes. Lorsque l'unité de transport en commun rentre à la station de rattachement, l'examen de la cassette permet d'analyser les circonstances des actes qui sont survenus . Un tel processus est satisfaisant en théorie mais l'est moins en pratique car il ne prévoit pas un contrôle du bon fonctionnement de l'équipement, sauf à demander au machiniste de remettre la cassette à chaque retour pour inspection technique et d'en prendre une nouvelle à chaque départ, ce qui constituerait pour lui une sujétion très importante.To find out the circumstances of acts of vandalism and / or violence, it is planned to use television cameras called video cameras which continuously record scenes taking place in a certain space of the public transport unit on a recording medium such as a magnetic tape in the form of a cassette or a magnetic disk the content of which can be extracted in the form of a removable cassette. When acts of vandalism and / or violence occur, the machinist of the transport unit initiates, for the camera and its recording medium, a process by which the camera continues to film the scene and to record it during a determined time, for example ten minutes, to stop this recording at the end of these ten minutes, so that the recording medium contains, for example, twenty minutes of recording or more depending on the size of the cassette, covering 10 minutes or more before the acts occur and the next 10 minutes. When the public transport unit returns to the home station, an examination of the cassette enables the circumstances of the acts that occurred to be analyzed. Such a process is satisfactory in theory but less so in practice because it does not provide for a check of the proper functioning of the equipment, except to ask the machinist to return the cassette on each return for technical inspection and to take one new at each departure, which would constitute for him a very important subjection.
Un but de la présente invention est donc de réaliser un système de surveillance d'unités de transport en commun dont le processus de fonctionnement est automatique, le machiniste n'intervenant qu'au moment des actes de vandalisme et/ou de violence pour signaler la survenance de tels actes par un dispositif d'alarme approprié.An object of the present invention is therefore to provide a system for monitoring public transport units whose operating process is automatic, the machinist only intervening at the time of acts of vandalism and / or violence to signal the occurrence of such acts by an appropriate alarm device.
Il est à noter que les systèmes actuels avec cassette ne prévoient que l'enregistrement de l'heure simultanément avec la scène filmée, ce qui ne permet pas une localisation géographique précise de la scène.It should be noted that current cassette systems only provide for the time recording simultaneously with the filmed scene, which does not allow precise geographic location of the scene.
Un autre but de la présente invention est donc de réaliser un système de surveillance d'unités de transport en commun dans lequel la localisation de l'unité de transport sur le trajet est enregistré avec précision en même temps que l'heure.Another object of the present invention is therefore to provide a system for monitoring public transport units in which the location of the transport unit on the journey is recorded precisely at the same time as the time.
Par ailleurs, les passagers des transports en commun ne reçoivent que peu ou pas d'information sur le déroulement de leur transport, sauf les annonces faites par le machiniste, annonces qui sont forcément en nombre limité par le fait que le machiniste a de nombreuses autres opérations à effectuer.In addition, passengers in public transport receive little or no information on the progress of their transport, except announcements made by the machinist, announcements which are necessarily limited in number by the fact that the machinist has many others operations to be carried out.
Un autre but de la présente invention est donc de réaliser, en combinaison avec le système de surveillance, un système d'information des passagers, par le son et l'image, les informations étant relatives au déroulement du trajet ou d'intérêt plus général.Another object of the present invention is therefore to achieve, in combination with the system of surveillance, a passenger and sound information system, information relating to the progress of the journey or of more general interest.
