Abstract
Description
La présente invention concerne un dispositif de surveillance continue, de la bonne marche des installations frigorifiques et de conditionnement d'air. The present invention relates to a device for continuous monitoring of the proper functioning of refrigeration and air conditioning installations.
Le fonctionnement de telles installations est généralement automatique, et, sauf en cas de surveillance humaine intensive, il est peu probable de déterminer l'origine d'une panne avant d'en avoir constaté les conséquences dans le temps. The operation of such installations is generally automatic, and, except in the case of intensive human supervision, it is unlikely to determine the origin of a failure before having noticed the consequences over time.
L'exemp.le le plus frappant étant celui des produits surgelés en distribution alimentaire. The most striking example being that of frozen products in food distribution.
En effet lorsqu'une panne de tout ou partie du système frigorifique se produit, il faudra bien souvent attendre de constater la perte de la marchandise, pour declencher l'intervention des services d'entretien extérieurs. In fact, when a breakdown of all or part of the refrigeration system occurs, it will often be necessary to wait until the loss of the goods is noticed, before triggering the intervention of external maintenance services.
Le dispositif selon l'invention permet de prévenir sans délais le service d'entretien agréé de toute anomalie relative au bon fonctionnement des installations, lesquelles sont susceptibles d'occasionner des dégâts matériels et immatériels. The device according to the invention makes it possible to immediately notify the approved maintenance service of any anomaly relating to the proper functioning of the installations, which are liable to cause material and immaterial damage.
I1 permet aussi d'intervenir, par télécommande, depuis le poste de surveillance, sur un appareil electrique quelconque placé à proximité des installations surveillées ou appartenant à celles-ci. It also makes it possible to intervene, by remote control, from the monitoring station, on any electrical device placed near the monitored installations or belonging to them.
Le dispositif comprend essentiellement (fig; 1) - des capteurs A dits "tout ou rien", comparant des grandeurs physique avec un point de consigne - des cartes logiques B recevant et mémorisant les informations en provenance des capteurs A - des capteurs C dits "proportionnels" mesurant des grandeurs physiques - des cartes de mesures analogiques D recevant les informations en provenance des capteurs C - des carters de télécommande E pouvant mettre sous/hors tension un ou plusieurs quelconque appareils électriques J - un transmetteur téléphonique composant automatiquement ; lors du franchissement du point de consigne par l'un des capteurs A ; le numéro d'appel du poste de surveillance PS auquel il est raccordé par une ligne téléphonique "rouge", s'identifiant par l'envoi d'un nombre à 4 chiffres et envoyant un message codé caractérisant le capteur ayant reagi à la variation d'une grandeur physique, ainsi qu'un message codé caractérisant la valeur des grandeurs physiques mesurées par les capteurs C - un poste de surveillance PS , recevant les appels et pouvant être connecte à (10.000 - 1) transmetteurs, le poste de surveillance décode les messages des transmetteurs et les transcrits sur une iUpriIarte I explicitant la nature du ou des défauts contatës, selon la liste - défaut thermique compresseur basse pression n" n* défaut haute pression compresseur basse pression n" n - défaut d'huile compresseur basse pression n" n - défaut thermique refroidisseurs de culasses compresseurs basse pression n - défaut thermique ventilateur condenseur basse pression n" x* - défaut température chambre froide surgelés - défaut ventilation chambre froide surgelés - defaut température bac surgelés - défaut température armoire surgelés - défaut thermique compresseur haute pression n" y* - défaut haute pression compresseur haute pression n) y - défaut d'huile compresseur haute-pression n" y - défaut thermique ventilateur condenseur haute pression n" z* - défaut température chambre froide boucherie - défaut ventilation chambre froide boucherie - défaut température chambre froide charcuterie - défaut ventilation chambre froide charcuterie - défaut température chambre froide cremerie - défaut ventilation chambre froide crémerie - défaut température linéaire boucherie - défaut température linéaire charcuterie - défaut température linéaire crémerie - défaut température linéaire ultra-frais - prise en glace bac surgeles- - prisé en glace armoire surgelés

Les grandeurs physique dont il est précédemment question ne font pas l'objet d'une liste limitative et sont principalement
- la température
- la pression
- la tension électrique
- l'intensité électrique
- le degré hygrometrique de l'air
- le débit de gaz ou de liquide
- le niveau de liquide dans une capacité
- le changement d'état d'un corps (eau en glace par exemple)
- formation de glace dans les ailettes d'un échangeur - un dispositif caractérisé en ce qu'il met hors-service le transmetteur téléphonique lors de l'intervention du service agréé sur l'armoire électrique principale de commande ae l'installation, ce, par détection optique de l'ouverture des portes de la dite armoire, à l'aide d'un emetteur-recepteur à rayon infra-rouge modulé, d'un réflecteur et d'un circuit de relayage temporisé. Ce dispositif ayant pour objet d'interdire tout appel intempestif consecutif à l'intervention du service agréé. The physical quantities of which it is previously question are not the object of an exhaustive list and are mainly
- temperature
- pressure
- electrical voltage
- electric intensity
- the humidity of the air
- the gas or liquid flow
- the liquid level in a capacity
- the change of state of a body (water to ice for example)
- formation of ice in the fins of an exchanger - a device characterized in that it deactivates the telephone transmitter during the intervention of the authorized service on the main electrical control cabinet of the installation, this, by optical detection of the opening of the doors of said cabinet, using a modulated infrared ray transceiver, a reflector and a timed relay circuit. The purpose of this device is to prohibit any untimely call following the intervention of the approved service.
