Abstract

The access control system has a control desk with slot to receive a card and ensure operation of a turnstile if the card is accepted. The card has rows of symmetric codes visible to radiation between 800 and 1,000 nm. The control unit has a reader comprising emitter (11) and receiver (12) for the radiation and a control circuit comprising a microprocessor with memory and a comparator. When the codes read by the receiver coincide with those in controller memory, the turnstile is released.

Description

L'objet du présent brevet d'invention concerne un système amélioré pour contrôler l'accès du public à des locaux et des enceintes divers, tels que installations sportives, clubs, terrains de jeu, etc. apportant de sensibles améliorations spécialement d'ordre de fiabilité, vérification et multiplicité de combinaisons de l'élément basique tel que la carte d'accès codifiée. Sont bien connus du public en général les systèmes actuels pour contrôler l'entrée dans divers milieux, consistant essentiellement en l'emploi d'une carte valable pour plusieurs passages ou entrées et une machine jointe à une porte qui est débloquée par le système. La carte doit être introduite dans une fente de cette machine qui l'identifie et, si elle est correcte, elle lui coupe un coupon ou lui permet l'accès à l'enceinte contrôlée, par la rotation de la porte pour que l'usager en question passe par celle-là. Lesdites machines sont généralement installées à l'entrée d'un local ou installation citée, évidemment. Cependant, ces systèmes connus ont plusieurs inconvénients centrés et dérivés des éléments basiques: la carte et l'organe lecteur. Ces cartes sont généralement de nature magnétique et codifiée conductivement ou perforée et portent le programme de performance incorporé à celle-là. Cela comporte plusieurs inconvénients, savoir: ledit programme exige que la carte se trouve en de bonnes conditions de conservation; la propre carte ne peut pas se détériorer car au moment où les bandes codifiées sont abîmées il peut y avoir des erreurs de lecture; par ailleurs, la vitesse d'introduction de la carte dans la fente de la machine peut également être la cause d'une lecture incorrecte.The object of this patent relates to an improved system for controlling public access to premises and various premises, such as sports facilities, clubs, playgrounds, etc. bringing appreciable improvements especially of reliability, verification and multiplicity of combinations of the basic element such as the coded access card. Are well known to the general public current systems for controlling entry into various environments, consisting essentially of the use of a card valid for several passages or entries and a machine attached to a door which is unlocked by the system. The card must be inserted into a slot in this machine which identifies it and, if it is correct, it cuts a coupon to it or allows it access to the controlled enclosure, by rotating the door so that the user in question goes through that one. Said machines are generally installed at the entrance to a room or installation mentioned, of course. However, these known systems have several central drawbacks derived from basic elements: the card and the reader device. These cards are generally magnetic in nature and coded conductively or perforated and carry the performance incorporated into that. This has several drawbacks, namely: said program requires that the card is in good storage conditions; the own card cannot deteriorate because at the time when the coded tapes are damaged there may be reading errors; moreover, the speed of insertion of the card into the slot of the machine can also be the cause of an incorrect reading.

La présente invention résout tous ces inconvénients en faisant que le système comporte, tout d'abord, une carte qui fonctionne par lecture par transparence, un dispositif lecteur de celle-là dans la machine qui donne un signal qui débloque la porte tournante, et des moyens de contrôle à chaque accès (s'il y en a plusieurs) branchés à un ordinateur central avec les programmes appropriés pour traduire les signaux des dispositifs lecteurs en ordres de déblocage et les accumuler pour un contrôle statistique.The present invention overcomes all these drawbacks by making the system comprise, first of all, a card which operates by reading by transparency, a reader device for this one in the machine which gives a signal which unlocks the revolving door, and control means at each access (if there are several) connected to a central computer with the appropriate programs for translating the signals from the reader devices into release orders and accumulating them for statistical control.

Avec tout cela ce système de codification permet que la carte soit identifiée avec des conditions de conservation moins exigentes, ce qui comporte une plus grande fiabilité de sa lecture; il ne dépend pas de la vitesse d'introduction dans la fente de la machine; et surtout, il permet d'obtenir des mise en oeuvre de cartes de types très différents: abonnements individualisés, abonnements horaires, abonnements saisoniers, cartes familiales, etc.With all this, this coding system allows the card to be identified with less demanding storage conditions, which makes it more reliable to read; it does not depend on the speed of insertion into the slot of the machine; and above all, it allows very different types of cards to be used: individual subscriptions, hourly subscriptions, seasonal subscriptions, family cards, etc.

Un autre aspect intéressant à remarquer dans ladite carte est que ses codifications sont disposées symétriquement par rapport aux axes longitudinal et transversal de celle-là. Cela, qui n'est pas non plus connu dans d'autres cartes, donne une commodité d'usage et évite qu'il faille se préoccuper de sa position correcte pour l'introduction dans la fente de la machine.Another interesting aspect to note in said map is that its codifications are arranged symmetrically with respect to the longitudinal and transverse axes thereof. This, which is also not known in other cards, gives convenience of use and avoids having to worry about its correct position for insertion into the slot of the machine.

Afin de faciliter l'explication, il est annexé à la présente description deux pages de dessins dans lesquelles il a été représenté un cas pratique de mise en oeuvre qui n'est cité qu'à titre d'exemple non limitatif de la portée du présent brevet d'invention. Dans lesdits dessins:In order to facilitate the explanation, two pages of drawings are annexed to the present description, in which a practical implementation case has been shown, which is cited only by way of non-limiting example of the scope of the present. patent. In said drawings:

La figure 1 représente un schéma général du système.Figure 1 shows a general diagram of the system.

La figure 2 est une vue en plan d'une carte.Figure 2 is a plan view of a map.

La figure 3 illustre une vue en coupe longitudinale en élévation de la fente ou rainure horizontale de la machine identificatrice avec une carte introduite dans celle-ci.FIG. 3 illustrates a view in longitudinal section in elevation of the slot or horizontal groove of the identifying machine with a card inserted therein.

Et la figure 4 correspond à une autre coupe longitudinale avec un agencement vertical de ladite fente de la machine identificatrice des cartes. Selon ces figures, (fig. 1), le système amélioré pour contrôler l'accès du public aux locaux et enceintes divers objet de la présente invention comprend principalement une carte -1-, l'accès -2- proprement dit, des moyens de contrôle -3- et, dans le cas où il y aurait plusieurs accès, un ordinateur central -4- intercommuniqué avec les moyens de chaque accès. Tout d'abord (fig. 2) la carte (1) consiste en une lame -1a- de support des codes imprimés -5- soit sous forme de barres, rectangulaires ou arrondis, agencés symétriquement par rapport aux axes longitudinaux -6- et transversal -7- de celle-là.And Figure 4 corresponds to another longitudinal section with a vertical arrangement of said slot of the machine identifying cards. According to these figures, (fig. 1), the improved system for controlling public access to premises and enclosures various object of the present invention mainly comprises a card -1-, the access -2- proper, control means -3- and, in the case where there are several accesses, a central computer -4- intercommunicated with the means of each access. First of all (fig. 2) the card (1) consists of a blade -1a- for supporting the printed codes -5- either in the form of bars, rectangular or rounded, arranged symmetrically with respect to the longitudinal axes -6- and transverse -7- of that one.

La même lame -1a- sera protégée par une seconde lame -1b- protectrice des rayonnements lumineux visibles. L'accès -2- comprend de façon conventionnelle une poupée lectrice -8- ayant une fente -9h- substantiellement horizontale pour l'introduction de cartes -1- et une porte ou tour tournant -10- déjà connu. Dans cette fente -9h- de la poupée -8- (fig. 3) sont logés: à l'entrée des jeux de transmetteurs -11- de rayonnements compris dans la longueur d'onde de 800 à 1.000 nm et des récepteurs -12- de ceux-ci en regard les uns des autres et coincidant avec chaque rangée de codes -5- de la carte -1-. A chaque côté de ladite fente -9h- il y a des supports opaques et isolants -13-, par exemple en bakélite, qui par leur face externe portent des respectives plaques de circuits imprimés -14- relatifs à ces emetteurs et récepteurs; sur leurs faces intérieures il y a une lame d'acier inoxydable -15- pour le glissement des cartes et un masque en matière plastique -16-. Dans le fond il y a une butée -17-.The same blade -1a- will be protected by a second blade -1b- protecting visible light radiation. Access -2- conventionally comprises a reader doll -8- having a slot -9h- substantially horizontal for the introduction of cards -1- and a revolving door or tower -10- already known. In this slot -9h- of the doll -8- (fig. 3) are housed: at the entrance of the sets of transmitters -11- of radiation included in the wavelength from 800 to 1,000 nm and receivers -12 - of these facing each other and coinciding with each row of codes -5- of the card -1-. On each side of said slot -9h- there are opaque and insulating supports -13-, for example in bakelite, which by their external face carry respective printed circuit boards -14- relating to these transmitters and receivers; on their inside there is a stainless steel blade -15- for swiping cards and a plastic mask -16-. In the bottom there is a stop -17-.

Alternativement (fig. 4) il a été prévu une fente -9v- substantiellement verticale, qui si bien elle compte sur les mêmes éléments avant décrits, compte de plus sur la butée du fond -18- qui est un simple dispositif de retention temporaire de la carte introduite. Plus bas il existe une plaque de déviation -19- qui, si la carte identifiée -1- lue est valable, dévie celle-ci vers le plateau de retour -20- pour que son propriétaire la recueille; si elle n'est pas correcte elle est déviée vers le dépôt collecteur -21-, toujours après que la butée -18- se retire éventuellement. Au contraire, on peut égalment disposer que dans le cas où la carte lue soit valable, celle-ci soit déviée vers le dépôt collecteur -21-; si elle ne l'est pas elle sera déviée vers le plateau de retour -20-. Les moyens de contrôle -3- d'accès comprennent un microprocesseur -22- composé basiquement par une mémoire -23- et un comparateur -24-, ainsi que lesdits dispositifs lecteurs -11-12- de l'intérieur de la poupée -8- existant de plus, aux postes de distribution de cartes, une unité de validation de cartes avec clavier -25- pour pouvoir lui introduire un code qui sera envoyé au microprocesseur -22- ou, le cas échéant, à l'ordinateur -4- et de celui-ci à toutes les portes ou accès -2-.Alternatively (fig. 4) a substantially vertical slit -9v has been provided, which if it counts on the same elements described above, also counts on the bottom stop -18- which is a simple temporary retention device for the card inserted. Below there is a diversion plate -19- which, if the card identified -1- read is valid, deflects it towards the return tray -20- so that its owner collects it; if it is not correct it is deflected towards the collector deposit -21-, always after the stop -18- eventually withdraws. On the contrary, it can also be arranged that in the case where the card read is valid, it is diverted to the collecting depot -21-; if it is not it will be diverted to the return plate -20-. The access control means -3- include a microprocessor -22- basically composed by a memory -23- and a comparator -24-, as well as said reader devices -11-12- from inside the headstock -8 - existing in addition, at distribution stations cards, a card validation unit with keypad -25- to be able to enter a code which will be sent to the microprocessor -22- or, if necessary, to the computer -4- and from it to all doors or access -2-.

Il est prévu une unité -26- de comparaison de tensions entre le signal reçu par chaque récepteur des éléments lecteurs -12- et une carte patron (non illustrée) pour vérifier l'épaisseur de chaque carte introduite. Il a également été prévu un bloc compteur -27- de cartes correspondant à diverses classes d'usagers et pouvoir établir un dénombrement indépendant de chaque classe.There is provided a unit -26- for comparing the voltages between the signal received by each receiver of the reader elements -12- and a master card (not shown) to check the thickness of each card inserted. Provision has also been made for a counter block -27- of cards corresponding to various classes of users and to be able to establish an independent count of each class.

Dans la pratique, lorsqu'on introduit une carte -1- dans la fente -9- les moyens lecteurs -12- identifient le code -5- de celle-là. Le microprocesseur -22- compare le code lu avec les codes programmés valables en ce moment; si le code est correct le mécanismo bloquant du tourniquet -10- est débloqué par "oui"et au moyen d'un système optique ou lumineux -28- il indique à l'usager que la porte est débloquée.In practice, when a card -1- is inserted into the slot -9- the reader means -12- identify the code -5- of that one. The microprocessor -22- compares the code read with the programmed codes valid at the moment; if the code is correct the blocking mechanism of the turnstile -10- is unlocked with "yes" and by means of an optical or light system -28- it indicates to the user that the door is unlocked.

Dans le cas de ne pas trouver un code programmé "non", il émettra un signal acoustique -29- et un autre lumineux ou visuel -30- différent à l'antérieur. Le microprocesseur -22- est doté d'un dispositif anti pass-back consistant en un certain programme pour que l'ordinateur de contrôle prenne connaissance des dernières cartes valables lues, de sorte que, avec une même carte une personne uniquement puisse entrer dans le local ou enceinte.In the case of not finding a programmed code "no", it will emit an acoustic signal -29- and another luminous or visual -30- different from the previous one. The microprocessor -22- is equipped with an anti pass-back consisting of a certain program for the control computer to take note of the last valid cards read, so that, with the same card only one person can enter the premises or enclosure.

Les lectures valables seront groupées dans le microprocesseur selon le code de celles-ci en augmentant à chaque lecture valable le numéro du compteur -27- du groupe correspondant, par example, les hebdomadaires, familiales, individuelles, horaires etc.The valid readings will be grouped in the microprocessor according to the code of these by increasing with each valid reading the number of the counter -27- of the corresponding group, for example, weeklies, family, individual, timetables etc.

Le nombre de lectures non valables seront égalmente comptabilisees afin de faire une statistique sur la bonté du système.
Pour rendre valable une certaine carte, on introduit les données dans le dispositif de validation -25- qui lit le mode et le numéro d'abonnement, celui-ci les transmet à l'ordinateur -4- qui les reçoit et vérifie. Ces données passent à la mémoire de cet ordinateur -4- qui à travers le modem -31- correspondant les transmet aux moyens de contrôle -3- de chacune des portes ou accès -2-; lorsqu'on fait une lecture sa validation se fait à la porte correspondante en augmentant de cette façon la rapidité de réponse du système.The number of invalid readings will also be counted in order to make a statistic on the goodness of the system.
To make a certain card valid, the data is entered into the validation device -25- which reads the mode and the subscription number, which transmits them to the computer -4- which receives and verifies them. These data pass to the memory of this computer -4- which through the corresponding modem -31- transmits them to the control means -3- of each of the doors or accesses -2-; when a reading is made, its validation is done at the corresponding door, thereby increasing the speed of response of the system.
