Abstract

The keyboard comprises n calibrated resistors 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 21 and keys 11, 12, 13, 14, 15, 16, 17, 18, 19, 20. An analogue/digital card several metres or kilometres away processes the various thresholds if a key is pressed. The line resistor 21 indicates to the card, by the threshold which it delivers, that no key has been pressed. If key 11 is pressed, the resistor 1 will be in parallel with the resistor 21. The analogue/digital card then processes this threshold and allocates it its binary value.

Description

Les lecteurs de controle d'accès dûs à leur conception, nécessitent
même si l'intelligence est déportée, un minimum de circuits intégres,et
le plus gênant "l'Organe principal" (relais le plus souvent) qui permet
la dernière transaction.Access control readers due to their design, require
even if intelligence is deported, a minimum of integrated circuits, and
the most troublesome "Main Organ" (relay most often) which allows
the last transaction.

. ouverture d'une porte ou d'une barrière, . mise Marche/Arrêt d'une machine ou d'un système d'alarme.. opening a door or a barrier,. On / Off of a machine or alarm system.

S'il y a effraction du lecteur, l'ouverture ou la Marche/Arrêt peut se réaliser par l'intrus ; et en cas de sabotage de l'appareil, le circuit électronique peut être détruit. Donc très croûteux pour la remise en état.If the reader breaks in, the opening or the On / Off can be done by the intruder; and in case of sabotage of the device, the electronic circuit can be destroyed. So very crusty for the restoration.

Bien que le traitement par voie analogique de n niveaux distincts (contact mettant en parallèle des résistances étalonnées) soit d'une réalisation facile, l'application au dispositif de contrôle d'accès de sécurité décrit ci-après, conduit aux propriétés originales suivantes
Aucun circuit électronique n'est nécessaire dans le coffret.Although the analog channel processing of n distinct levels (contact paralleling calibrated resistors) is easy to achieve, the application to the security access control device described hereinafter leads to the following original properties
No electronic circuit is necessary in the box.

En cas d'effraction, aucune possibilité d'intrusion. En cas de sabotage, une alarme coupure ligne ou court-circuit est délivrée à l'utilisateur.In case of break-in, no possibility of intrusion. In case of sabotage, a line or short-circuit interruption alarm is delivered to the user.

Aucune alimentation n'est nécessaire dans le coffret et le nombre important de fils à connecter est réduit à deu
Déportation d'un ou de plusieurs lecteurs sur la même unité centrale à une distance maximale de 10 Kilomètres de celle-ci.No power supply is needed in the cabinet and the large number of wires to be connected is reduced to two
Deportation of one or more drives on the same CPU at a maximum distance of 10 kilometers from it.

Plus besoin à l'utilisateur de se déplacer au lecteur pour modifier le code confidentiel à tabuler. No need for the user to move to the reader to change the PIN to tab.

Le code peut être changé à volonté, il peut avoir un nombre de chiffres illimité, peut passer d'un code commun à toutes les personnes aux codes individuelles à chacune des personnes utilisant le même lecteur.The code can be changed at will, it can have an unlimited number of digits, can pass from a code common to all people to the individual codes to each of the people using the same reader.

La seule intervention du service après-vente pour ce lecteur sera pour l'échange standard dû au vieillissement naturel du clavier : 5.000.000 de manoeuvres.  The only intervention of the after-sales service for this reader will be for the standard exchange due to the natural aging of the keyboard: 5,000,000 of maneuvers.

LECTEUR A RESISTANCE.RESISTANCE READER.

Chacune des touches pressées, délivre un seuil différent à la carte analogique/numérique qui lui attribue une valeur binaire qui sera traitée par microprocesseur. Each key pressed, delivers a different threshold to the analog / digital card that assigns a binary value that will be processed by microprocessor.

Seuil = RL (resistance de ligne) aucune touche n'est pressée.Threshold = RL (line resistance) no key is pressed.

Seuil = RL/R1 La touche est pressée.Threshold = RL / R1 The key is pressed.

Seuil = ohm Court-circuit sur la ligne.Threshold = ohm Short circuit on the line.

Seuil = Infini# coupure ee ligne.Threshold = Infinite # line break.

Si l'ordre des toucnes pressées correspond au code mis en mémoire, 1' autorsation est délivrée. If the order of the keys pressed corresponds to the code stored in memory, the autorsation is delivered.

Le lecteur à résistances comprend : 1 clavier et des résistances étalonnées. The resistance reader includes: 1 keyboard and calibrated resistors.

Les résistances étalonnées peuvent être remplacées par des diodes zéners de différentes valeurs.The calibrated resistors can be replaced by zener diodes of different values.

Les résistances étalonnées peuvent être remplacées par des condensateurs.Calibrated resistors can be replaced by capacitors.

Le traitement au niveau de l'intelligence déportée change mais le principe reste le même.The treatment at the level of the deported intelligence changes but the principle remains the same.

Pour les lieux à atmosphère déflagrante (sites pétroliers ; cimenteries, silos à grains, etc...) le lecteur se modifie de la manière suivante
On remplace les contacts à fermeture par ces I. L. S. (ampoule ride), les touches par des boutons poussoirs munis d'aimants pour fermer le contact de 1'I. L. S. en travail, et le tout est roulé dans la matière avec les résistances. For places with an explosive atmosphere (oil sites, cement plants, grain silos, etc ...) the reader changes as follows
The closing contacts are replaced by these ILSs (wrinkle bulb), the keys by push buttons provided with magnets to close the contact of the ILS in work, and everything is rolled into the material with the resistors.
