Description

La présente invention concerne un nouveau système d'adresse destiné à constituer une centrale d'informations permettant de dialoguer avec différents détecteurs de fumées munis de circuits intégrés .Cette centrale affiche sur un tableau de visualisation les informations relatives à un sinistre,le défaut de fonction­nement, le lieu du sinistre ou de l'incident,le bon fonctionnement du circuit,quelles que soient les caractéristiques des capteursThe present invention relates to a new address system intended to constitute an information center making it possible to dialogue with different smoke detectors provided with integrated circuits. This central displays on a display board the information relating to a disaster, the malfunction , the location of the disaster or incident, the proper functioning of the circuit, whatever the characteristics of the sensors

On utilisait jusqu'à présent des installations comportant différents détecteurs de fumées dispersés sur un site qui détec­taient ponctuellement un sinistre et déclenchaient une alarme visuelle ou sonore sur le site .Certaines améliorations sont intervenues et ont consisté à raccorder ces détecteurs à une centrale qui enregistrait l'alarme ou l'incident sans pouvoir déterminer le lieu . Dans ce dernier cas, il était nécessaire de localiser le sinistre en effectuant une inspection de tous détecteurs de l'installation .Until now, we have used installations with different smoke detectors dispersed on a site which punctually detected a disaster and triggered a visual or audible alarm on the site. Some improvements were made and consisted in connecting these detectors to a central unit which recorded the alarm or incident without being able to determine the location. In the latter case, it was necessary to locate the incident by carrying out an inspection of all the detectors in the installation.

La présente invention permet de résoudre ces inconvénients connectant en parallèle sur un même tableau les différents détecteurs placés sur le site et en traitant les informations issues des circuits intégrés inclus dans chaque capteur .The present invention makes it possible to resolve these drawbacks by connecting the various detectors placed on the site in parallel on the same panel and by processing the information from the integrated circuits included in each sensor.

On détermine ainsi l'adresse du capteur et la nature de l'information émise par celui-ci . Ces différentes informations forment un dialogue entre la centrale et les détecteurs .This determines the address of the sensor and the nature of the information sent by it. This different information forms a dialogue between the central unit and the detectors.

L'invention ainsi définie présente de nombreux avantages, et notamment :
Une gestion centralisée de l'état de fonctionnement de chaque détecteur ,
- Une localisation rapide de l'alarme,
- Un fonctionnement continu de l'ensemble même au cas où un détecteur est devenu hors d'usage,
- Une mémorisation des incidents survenus durant la période de détection .The invention thus defined has numerous advantages, and in particular:
Centralized management of the operating status of each detector,
- Rapid localization of the alarm,
- Continuous operation of the assembly even if a detector has become out of order,
- Memorization of incidents that occurred during the detection period.
