Abstract

The invention relates to a device facilitating the automatic electrical supply of small electronic systems, according to need, should the supply via the mains be cut or fail. It consists of a battery 1 which may optionally be recharged by a conventional charger, and which is connected to a regulator 2 (whose output voltage can be adapted to that of the system to be protected), supplying an electronic unit 3 whose purpose is to establish the connection of the device once the supply voltage of the system to be protected has dropped from a value S corresponding to the threshold for switching this unit. The device according to the invention is intended to secure the electrical supply of small electronic systems such as microcomputers and specific terminals, in particular badge readers.

Description

La presente invention concerne un dispositif pour la securité d'alimentation electrique de petits systemes electroniques. The present invention relates to a device for the power supply security of small electronic systems.

La sécurité d'alimentation électrique des petits systèmes électroniques est traditionnellement effectuée à l'aide d'onduleurs; appareils qui sont branchés entre la prise de courant et le système a alimenter et qui fournissent a ce dernier un courant produit par l'intermédiaire de batteries tampons rechargées par le secteur en dehors des coupures de celui-ci. The power supply security of small electronic systems is traditionally carried out using inverters; devices which are connected between the socket-outlet and the system to be supplied and which supply the latter with a current produced by means of buffer batteries recharged by the sector outside of the latter's interruptions.

Ces onduleurs sont en général lourds, encombrants et chers pour une puissance donnée et doivent fonctionner en permanence lorsque l'appareil à protéger est sous tension. These inverters are generally heavy, bulky and expensive for a given power and must operate continuously when the device to be protected is energized.

Le dispositif selon l'invention permet de remédier à ces inconvénients d'encombrement,de poids,d'utilisation constante et de prix relativement élevé par rapport à celui du systdme à protéger, il est basé sur le principe d'un secours, n'intervenant qu'en cas de besoin, qui s'insère dans le systEme,non pas à l'arrivée du courant secteur, mais au niveau de la basse tension redressée nécessaire au fonctionnement du système à protéger et dont l'intervention en cas dé nécessité se produit de façon entièrement automatique,sans aucune répercussion fâcheuse pour le système a protéger, il en est de même pour sa mise hors circuit lorque les conditions normales d'alimentation sont rétablies. The device according to the invention overcomes these drawbacks of space, weight, constant use and relatively high price compared to that of the system to be protected, it is based on the principle of backup, n ' intervening only in case of need, which is inserted in the system, not at the arrival of the mains current, but at the level of the rectified low voltage necessary for the functioning of the system to be protected and whose intervention in case of necessity occurs entirely automatically, without any untoward repercussions for the system to be protected, it is the same for its shutdown when normal conditions of supply are restored.

Ce dispositif qui résout parfaitement les problèmes posés par les baisses de tension du secteur, les microcoupures et les coupures franches comprend
Des batteries qui peuvent être éventuellement rechargées par un
chargeur classique type chargeur de batterie.This device, which perfectly solves the problems posed by mains voltage drops, micro-cuts and sharp outages, includes
Batteries which can possibly be recharged by a
classic charger type battery charger.

Un régulateur de courant. A current regulator.

Un bloc électronique de commutation dont la sortie se branche au
point (désigné ci-apres par A) d'arrivée du courant continu basse
tension destiné à alimenter l'appareil à protéger.An electronic switching unit whose output connects to the
low direct current arrival point (hereinafter referred to as A)
voltage intended to supply the device to be protected.

Le dispositif objet de l'invention fonctionne de la façon suivante; des que la tension au point A baisse,en voltage,d'une quantité supérieure ou ou égale au seuil (S) de communtation du bloc électronique, le dispositif se commute automatiquement grâce à l'intervention de ce bloc de maniere à compenser la baisse de tension détectée, sa batterie débite alors sur le régulateur qui est taré à (X - S) volts X étant la tension d'alimentation continue de l'appareil à proteger qui peut avoir une valeur suivant les appareils comprise entre S et 24 volts. Tant que le secteur n'a pas ramené la tension d'alimentation au point (A) à la valeur (X) la batterie continue à débiter suivant la demande du système secouru. Dès que la valeur (X) est atteinte le bloc électronique déconnecte alors automatiquement le dispositif.The device which is the subject of the invention operates in the following manner; as soon as the voltage at point A drops, in voltage, by an amount greater than or equal to the communication threshold (S) of the electronic block, the device is automatically switched thanks to the intervention of this block so as to compensate for the drop voltage detected, its battery then flows on the regulator which is rated at (X - S) volts X being the continuous supply voltage of the device to be protected which can have a value depending on the devices between S and 24 volts. As long as the sector has not reduced the supply voltage at point (A) to the value (X), the battery continues to charge according to the request of the backed-up system. As soon as the value (X) is reached the electronic unit then automatically disconnects the device.

Suivant le cas il peut être intéressant comme il a été signalé cidessus d'adjoindre un chargeur qui dès que le dispositif n'est plus en service rechargera de façon automatique les batteries pour ramener cellesci à leur charge d'origine. Depending on the case, it may be advantageous as mentioned above to add a charger which as soon as the device is no longer in use will automatically recharge the batteries to bring them back to their original charge.

ta description ci-dessus montre la souplesse d'un tel dispositif qui peut être construit exactement en fonction des besoins du système à pro téger et de la durée de la protection souhaitée, si bien qu'un dispositif spécialement orienté vers la protection contre les microcoupures et le secours de courte durée pourrait être,grace à son faible encombrement, intégré dans les coffrets des appareils à protéger (micro-ordinateurs par exemple). your description above shows the flexibility of such a device which can be constructed exactly according to the needs of the system to be protected and the duration of the desired protection, so that a device specially oriented towards protection against micro-cuts and short-term assistance could be, thanks to its small footprint, integrated in the boxes of the devices to be protected (microcomputers for example).

La figure (1) représente le dispositif (D), équipé d'un chargeur de batterie (C) (comprenant un transformateur T, un redresseur R et un générateur G) raccordé au point (A) de l'alimentation d'un microprocesseur (M), La batterie (t) du dispositif (D) est connectée à un régulateur (2) (dont la tension de sortie réglable est à ajuster à celle du système à protéger) qui alimente le bloc électronique (3) chargé de la commutation automatique. Figure (1) represents the device (D), equipped with a battery charger (C) (comprising a transformer T, a rectifier R and a generator G) connected to point (A) of the power supply of a microprocessor (M), The battery (t) of the device (D) is connected to a regulator (2) (whose adjustable output voltage is to be adjusted to that of the system to be protected) which supplies the electronic unit (3) responsible for the automatic switching.

Le dispositif selon l'invention est destiné a assurer la sécurité d'alimentation électrique de systèmesélectroniques tels que micro-ordinateurs, terminaux spécifiques, en particulier lecteurs de badges et en général tous appareils éléetroniques du même genre et de tous ceux pouvant en découler.  The device according to the invention is intended to ensure the security of the electrical supply of electronic systems such as microcomputers, specific terminals, in particular badge readers and in general all electronic devices of the same kind and of all those which may arise therefrom.
