CA 2740199

A system and a method for controlling a set of bistable solenoids for applications for the locking of access means such as doors/gates or containers, where the direct connection of the energy source with the solenoid is eliminated by means of the introduction of a capacitor and a switch between the power source and the solenoid, thus eliminating the need for a dedicated H-bridge for each solenoid and reducing the power and control lines required for each solenoid such that, after the initial control lines, each subsequent solenoid requires only a control line for selecting the appropriate solenoid.

L'invention concerne un système et un procédé de commande d'un ensemble de solénoïdes bistables destinés à des applications de fermeture de moyens d'accès tels que des portes ou des tiroirs, dans lesquels on élimine la connexion directe de la source d'énergie avec le solénoïde par l'introduction d'un condensateur et d'un interrupteur entre la source de puissance et le solénoïde, ce qui permet d'éliminer ainsi la nécessité d'un pont en H spécifique pour chaque solénoïde, et de réduire ainsi les lignes d'énergie et de commande requises pour chaque solénoïde, de telle façon qu'après les lignes de commande initiales, chaque solénoïde subséquent ne requiert qu'une ligne de commande pour sélectionner le solénoïde approprié.
