Abstract

The present invention relates to a system of encoded (5) infrared volume sensors (1) and (2), situated above each car space (10) in an underground car park, in order to make it possible to manage the free and occupied spaces using a microcomputer (15), by knowing their geographical situation in the car park. The data from the sensors (1) and (2) are transmitted in frequency multiplexing by a central unit (12) in a coaxial bus (13). The system also makes it possible to continuously monitor the occupation of preindicated spaces over time and to trigger an alarm if the space becomes free before the limit fixed with the computer.

Description

DESCRIPTION SYSTEME DE GESTION DE PLACES DE PARKING
La presente Invention concerne un système de capteurs de presence de véhicules dans les places delimitees d'un parking. La principale difficulté de gestion des places de parking venant du fait a) de l'imprecision des systèmes de comptage en entrée et
sortie b) de l'impossibilite de savoir dans quel secteur du
parking, les places sont disponibles c) de ne pouvoir, de ce fait, indiquer aux utilisateurs,
ces secteurs.DESCRIPTION OF PARKING SPACE MANAGEMENT SYSTEM
The present invention relates to a system of sensors for the presence of vehicles in the delimited spaces of a parking lot. The main difficulty in managing parking spaces is due to a) the imprecision of the counting systems at the entrance and
exit b) the impossibility of knowing in which sector of the
parking, spaces are available c) not being able, therefore, to indicate to users,
these sectors.

Ces inconvenients provoquent, en general, une perte d'exploitation de i# à 15 * des places potentielles pour le gestionnaire, et une perte de temps pour les utilisateurs obligés de chercher les places libres dans les differentes travees du parking.These drawbacks cause, in general, a loss of exploitation of i # to 15 * of the potential places for the manager, and a loss of time for the users obliged to look for the free places in the different spans of the car park.

Les systèmes existants à l'heure actuelle presentent tous de nombreux inconvenients ne permettant pas une gestion à Nla place près, La detection par boucle magnetique sur les passages est totalement aleatoire (un chariot metallique declenche le système comme une voiture). Les detecteurs de volume H.F. ou hyper-fréquence sont totalement inoperents dans le milieu physique d'un parking dont l'armature fer du belon rend les propagations aleatoires. Les capteurs à ultra-sons sont déclenches par les volumes d'air deplaces par les souffleries et sont trops sensibles au milieu ambiant (gaz d'echappement venant deposer sur les emetteurs piezzo des hydrocarbures) pour permettre un fonctionnement satisfaisant.D'autre part, tous ces systèmes sont ou limites en capacite pour un temps de reaction normal, ou affectes d'un temps de reaction trop long pour entre efficaces. The existing systems at present all present numerous drawbacks which do not allow management except for the near place. The detection by magnetic loop on the passages is completely random (a metal trolley triggers the system like a car). The H.F. or hyper-frequency volume detectors are totally inoperative in the physical environment of a car park, the belon iron frame of which makes the propagation random. The ultrasonic sensors are triggered by the volumes of air displaced by the blowers and are very sensitive to the ambient environment (exhaust gas coming to deposit on the piezoelectric emitters of hydrocarbons) to allow a satisfactory operation. all these systems are either limited in capacity for a normal reaction time, or affected by a reaction time too long to be effective.

Tous ces inconvenients sont elimines par la presente
Invention dont le système de détection est basé sur des infra-rouge codes, chaque capteur etant équipé d'un emetteur et de 2 recepteurs directionnels, l'un des 2 recepteurs n'etant sollicite que lorsqu'une masse equivalente à une voiture est presente (donc occupation de la place). La directivite des recepteurs etant obtenue par des canons cylindriques dont l'angle d'inclinaison depend de la hauteur au-dessus du sol du capteur. Ces capteurs sont relies par groupe de 16, 32 ou 64 à une micro-centrale de commande qui declenche à tour de rôle l'emetteur et les recepteurs de chaque capteur suivant un cycle global ne depassant pas 1 seconde. De ce fait, la detection ne concerne que la place explore, et celle-ci est contrôlée chaque seconde.All these disadvantages are eliminated by this
Invention whose detection system is based on infrared codes, each sensor being equipped with a transmitter and 2 directional receivers, one of the 2 receivers being solicited only when a mass equivalent to a car is present (therefore occupation of the place). The directivity of the receivers being obtained by cylindrical barrels whose angle of inclination depends on the height above the ground of the sensor. These sensors are connected in groups of 16, 32 or 64 to a micro-central control unit which in turn triggers the transmitter and receivers of each sensor according to an overall cycle not exceeding 1 second. Therefore, the detection only concerns the explored place, and this is checked every second.

La mise en memoire des informations permet de confirmer L'état de la place sur 2 ou 3 cycles et d'eliminer ainsi le simple passage d'un vehicule sans occupation permanente.Storing the information confirms the state of the space over 2 or 3 cycles and thus eliminates the simple passage of a vehicle without permanent occupation.

L'information definitive est alors envoyee sur un modulateur en frequence qui permet de transmettre les informations de la micro-centrale, en serie, sur un bus coaxial travaillant en multiplexage de fréquences vers une station de démodulation. Cette technique de transmission permet de disposer, en simultané, des informations de l'ensemble des micro-centrales equipant le parking, quel que soit leur nombre, et assure ainsi une capacite de gestion permettant de répondre aux plus grands ensembles existants ou à venir. La capacité d'un bus coaxial etant, sur des distances moyennes de 3 Km de 7## micro-centrales, soit 224~~ capteurs en moyenne.The final information is then sent on a frequency modulator which makes it possible to transmit the information from the micro-central, in series, on a coaxial bus working in frequency multiplexing towards a demodulation station. This transmission technique makes it possible to have information simultaneously from all of the micro-power stations equipping the car park, whatever their number, and thus ensures a management capacity making it possible to respond to the largest existing or future complexes. The capacity of a coaxial bus being, over average distances of 3 km of 7 ## micro-power stations, that is to say 224 ~~ sensors on average.

Les informations demodulées sont, toujours en simultané, disponibles et explorees par paquet pour être traitees par un micro-ordinateur. Le logiciel, adapte au type de parking, permet de ressortir l'adresse de l'information transmise et de la comptabiliser. De ce fait, il est possible d'indiquer sur un ecran, le ou les secteurs, suivant un ordre pré-établi, où des places sont disponibles. The demodulated information is, always simultaneously, available and explored in packets to be processed by a microcomputer. The software, adapted to the type of parking, makes it possible to highlight the address of the information transmitted and to record it. Therefore, it is possible to indicate on a screen, the sector or sectors, in a pre-established order, where places are available.

Ces écrans, situés aux passages "entrée" du parking, permettent à l'utilisateur de se diriger directement vers le secteur libre, où il repère visuellement les places libres par une signalisation lumineuse des capteurs de ces places (les capteurs sur places occupées étant éteints).These screens, located at the "entrance" passages of the car park, allow the user to go directly to the free sector, where he visually identifies the free spaces by a light signaling of the sensors of these spaces (the sensors on occupied spaces being switched off ).

Lorsque toutes les places sont occupées, l'ordinateur affiche "Complet" sur les visues des entrées.When all the places are occupied, the computer displays "Full" on the entrance displays.

Le temps de réaction du système est de l'ordre de 5 secondes, ce qui est inférieur au temps de passage d'un véhicule à une entrée de parking (1~ à 14 secondes).The reaction time of the system is around 5 seconds, which is less than the time it takes for a vehicle to enter a parking lot (1 ~ 14 seconds).

Le couplage du signal "Complet" bloque la barrière, l'utilisateur en attente devant attendre alors la libération d'une place pour pénétrer dans le parking; ceci, se faisant des la libération d'une place, accélère les rotations et augmente sensiblement le taux de rendement du parking.The coupling of the "Full" signal blocks the barrier, the user on standby having to wait for the release of a space to enter the car park; this, being made free of a place, accelerates the rotations and appreciably increases the rate of return of the parking lot.

En dehors du service de gestion dynamique des places dans le parking, le système permet, du fait de l'exploration permanente de chaque place, de contrôler la présence d'un véhicule dans le temps. Le logiciel utilisé permet de saisir une durée déterminée sur une place précise. De ce fait un utilisateur, signalant le numéro de la place (indiquee au sol) et la durée prévue de son stationnement (jour - semaine), est certain que son véhicule ne peut être déplacé sans déclencher une alarme pendant cette période.Apart from the dynamic management service of parking spaces, the system allows, due to the permanent exploration of each space, to control the presence of a vehicle over time. The software used allows you to enter a specific duration on a specific place. Therefore a user, reporting the number of the place (indicated on the ground) and the expected duration of his parking (day - week), is certain that his vehicle cannot be moved without setting off an alarm during this period.

La planche unique représente l'ensemble du système mis en place dans un parking. Le capteur (1) , au-dessus d'une place libre, n'a pas le récepteur IR t4) sollicite par l'émetteur t6) dont le faisceau (8) est réfléchi en (9) la lampe (7) est alimentée en permanence par la Centrale (12)
Le capteur (2) est au-dessus d'un véhicule et le récepteur t4) est sollicité par la réflexion (9) du faisceau (8) émis par l'émetteur (6) , la lampe (7) du capteur t2) est éteinte. The single board represents the entire system implemented in a car park. The sensor (1), above a free space, does not have the IR receiver t4) requested by the emitter t6) whose beam (8) is reflected at (9) the lamp (7) is powered permanently by the Central (12)
The sensor (2) is above a vehicle and the receiver t4) is requested by the reflection (9) of the beam (8) emitted by the transmitter (6), the lamp (7) of the sensor t2) is extinct.

La centrale (12) envoie l'information "Libre" du capteur (i) et l'information "Occupée" du capteur (2) en modulation de fréquence à la Centrale (14) . Cette fréquence propre à la centrale (12) permet de connaître sa position géographique dans le parking, et l'ordinateur (15) peut afficher sur les écrans (16) qu'une place (ou X) est disponible dans le secteur de la Centrale (12) (travée H du 3eme sous-sol par exemple).The control unit (12) sends the "Free" information from the sensor (i) and the "Busy" information from the sensor (2) in frequency modulation to the Control unit (14). This frequency specific to the central (12) allows to know its geographical position in the parking lot, and the computer (15) can display on the screens (16) that a place (or X) is available in the Central sector. (12) (span H of the 3rd basement for example).

De même, si le propriétaire du véhicule (l~) a signalé que son absence serait de 2 semaines, pendant ce délai l'ordinateur (15) va contrôler en permanence l'occupation de la place du capteur (2) de la Centrale (12 > . Si le véhicule (l~) venait à être déplacé avant la limite du délai, une alarme serait donnée par la Centrale (14) de façon sonore et visuelle. Les issues du parking seraient alors bloquées. Similarly, if the owner of the vehicle (l ~) has indicated that his absence would be 2 weeks, during this period the computer (15) will constantly monitor the occupancy of the sensor space (2) of the control unit ( 12>. If the vehicle (l ~) were to be moved before the time limit, an alarm would be given by the control unit (14) audibly and visually, the parking exits would then be blocked.

Ce système est particulièrement adapté aux parkings de moyenne et grande capacité, pour les centres villes ou les aéroports, où les temps de saturation sont importants. Il permet d'une part de remplir à l~~ % le parking à ses moments de saturation, d'autre part de diminuer d'une façon très importante, le temps passé à chercher une place libre pour l'utilisateur. This system is particularly suitable for medium and large capacity car parks, for city centers or airports, where saturation times are long. It allows on the one hand to fill ~~% the parking lot at its moments of saturation, on the other hand to reduce in a very important way, the time spent looking for a free place for the user.
