Description

L'invention concerne un procédé et un dispositif pour la signalisation optique des perturbations d'une installation de chauffe ou d'une partie d'une installation de chauffe.The invention relates to a method and a device for optical signaling. disturbances of a heating installation or part of a heating installation heated.

Les installations de chauffe utilisant du fuel, du gaz ou d'autres combustibles pour produire de la chaleur, sont mises en oeuvre tant dans les habitations que dans l'industrie. Les installations de chauffe au gaz et au fuel notamment comportent un brûleur servant à démarrer et entretenir le processus de combustion. Le régime de démarrage ainsi que le fonctionnement du brûleur sont normalement contrôlés de façon automatique.Heating installations using fuel oil, gas or other fuels to produce heat, are used both in homes and in industry. The gas and oil heating installations in particular include a burner used to start and maintain the combustion process. The diet of start-up and burner operation are normally checked from automatically.

On connaít un dispositif pour la signalisation optique des perturbations d'une installation de chauffe, notamment d'une panne fonctionnelle de l'installation de chauffe à la suite d'un arrêt fonctionnel du brûleur, où la perturbation est signalée grâce à l'allumage ininterrompu d'un moyen lumineux. Afin d'assurer une suppression rapide de la panne, le dispositif relève le type de la perturbation, attribue un nombre aux diverses perturbations possibles et affiche le nombre concerné dans un regard en faisant tourner une roue portant les nombres sur sa circonférence.We know a device for optical signaling of disturbances of a heating installation, in particular a functional breakdown of the installation of heats up following a functional burner shutdown, where the fault is signaled thanks to the uninterrupted lighting of a luminous medium. In order to ensure rapid elimination of the fault, the device detects the type of disturbance, assign a number to the various possible disturbances and display the number concerned in a look by spinning a wheel carrying the numbers on its circumference.

S'orientant sur l'évolution technique générale, l'invention a pour objectif de réaliser un système de surveillance électronique d'une installation de chauffe qui se passe de tout dispositif d'affichage mécanique et permet néanmoins un diagnostic aisé des perturbations.Oriented on general technical development, the invention aims to create an electronic monitoring system for a heating installation which goes from any mechanical display device and nevertheless allows a diagnosis easy disturbances.

La présente invention a donc pour tâche de proposer un procédé pour la signalisation optique des perturbations d'une installation de chauffe ou d'une partie d'une installation de chauffe, notamment d'un brûleur. Une seconde tâche de la présente invention est de proposer un dispositif adéquat sensiblement exempt d'usure et dont les éléments constitutifs sont aussi peu encombrants que possible.The present invention therefore has the task of proposing a method for the optical signaling of disturbances in a heating installation or part a heating installation, in particular a burner. A second task of the present invention is to provide a suitable device substantially free wear and the components of which are as compact as possible.

Conformément à l'invention, ces tâches sont réalisées par un procédé présentant les caractéristiques de la revendication 1 et par un dispositif présentant les caractéristiques de la revendication 7. Certaines variantes de l'invention font l'objet des sous-revendications respectives.According to the invention, these tasks are carried out by a method having the features of claim 1 and by a device having The features of claim 7. Certain variants of the invention make the subject of the respective subclaims.

Suivant le procédé selon l'invention, l'apparition et le type d'une perturbation fonctionnelle sont détectés par un microprocesseur, puis des données relatives à un signal attribué au type de perturbation sont enregistrées dans une mémoire, ledit signal étant visualisé périodiquement ou sur appel grâce à un afficheur optique. En alternative à l'affichage périodique ou l'affichage sur appel, le signal est affiché après un ou plusieurs intervalles de temps suivant l'apparition de la perturbation, par exemple après une minute, dix minutes ou trente minutes. Un appel d'affichage peut se faire une ou plusieurs fois au lieu ou en complément de cela.According to the method according to the invention, the appearance and the type of a disturbance functional are detected by a microprocessor, then data relating to a signal assigned to the type of disturbance are recorded in a memory, said signal being viewed periodically or on call through an optical display. In alternative to periodic display or call display, the signal is displayed after one or more time intervals following the appearance of the disturbance, by example after one minute, ten minutes or thirty minutes. A display call can be done one or more times instead of or in addition to this.

Selon une variante du procédé, le signal se présente sous la forme d'une série d'impulsions attribuée au type de la perturbation concernée, qui est transformée au niveau de l'afficheur optique en une série d'impulsions optiques, de préférence lumineuses. Les afficheurs optiques peuvent comporter, par exemple, des diodes électroluminescentes ou des lampes incandescentes. La préférence est données aux variantes du procédé selon lesquelles un certain nombre d'impulsions lumineuses, de préférence des impulsions lumineuses de durée égale, sont attribuées à chacune des perturbations.According to a variant of the method, the signal is in the form of a series of pulses attributed to the type of disturbance concerned, which is transformed at the level of the optical display into a series of optical pulses, preferably bright. Optical displays can include, for example, light emitting diodes or incandescent lamps. Preference is given to variants of the process whereby a number of pulses light, preferably light pulses of equal duration, are attributed to each of the disturbances.

Selon une seconde variante du procédé, l'afficheur optique signale l'apparition d'une perturbation d'abord par un signal continu et n'émet la série d'impulsions attribuée au type de la perturbation qu'après l'appel d'affichage entré par l'opérateur. Par signal continu on entend, par exemple, l'allumage ininterrompu d'une ou de plusieurs diodes électroluminescentes. Un avantage de cette variante du procédé réside dans le fait qu'un seul afficheur optique suffit pour signaler tant la présence d'une perturbation que le type de la perturbation. Un dispositif adapté peut donc être placé derrière une paroi de protection comportant une ouverture pour l'afficheur optique.According to a second variant of the process, the optical display signals the appearance of a disturbance first by a continuous signal and does not emit the series of pulses assigned to the type of disturbance only after the display call entered by the operator. Continuous signal means, for example, uninterrupted ignition one or more light emitting diodes. An advantage of this variant of the process lies in the fact that a single optical display is sufficient to indicate both the presence of a disturbance as the type of disturbance. A suitable device can therefore be placed behind a protective wall with an opening for the optical display.

Il s'avère favorable que l'appel d'affichage de la série d'impulsions attribuée au type de la perturbation soit déclenché au moyen d'un bouton. Selon une variante particulièrement préférée, le même bouton sert également à la remise en fonctionnement de l'installation de chauffe ou de la partie concernée de cette installation de chauffe. Lorsque l'actionnement continu du bouton durant un intervalle dépasse un intervalle prédéfini, il déclenche l'appel d'affichage de la série d'impulsions attribuée au type de la perturbation. Cet intervalle peut être défini, par exemple, par une durée de 3 à 5 secondes.It turns out that the call to display the series of pulses assigned the type of disturbance is triggered by a button. According to a variant particularly preferred, the same button is also used to reset operation of the heating installation or the relevant part of it heating installation. When the continuous pressing of the button during a interval exceeds a predefined interval, it triggers the call to display the series of pulses attributed to the type of disturbance. This interval can be defined, by example, by a duration of 3 to 5 seconds.

Un exemple de réalisation du procédé selon l'invention est donné ci-après : dès l'apparition d'une perturbation dans une installation de chauffe, l'alimentation du combustible est immédiatement coupée, ce qui est signalé par un signal continu se traduisant par l'allumage ininterrompu de deux diodes électroluminescentes. L'actionnement d'un bouton pendant une durée de 3 secondes au moins, efface le signal continu et déclenche l'émission d'une série d'impulsions lumineuses de durée égale attribuée au type de la perturbation. Dans la présente description, une série d'impulsions lumineuses peut être synonyme d'une impulsion lumineuse unique. Dans une installation de chauffe comportant un brûleur à soufflerie, c'est-à-dire une chambre de combustion fermée, une impulsion lumineuse unique signifie qu'un pressostat a signalé un défaut avant le démarrage de la soufflerie et qu'une perturbation est donc intervenue. Un autre exemple de la signification d'une série d'impulsions lumineuses est celle d'une série de six impulsions lumineuses. Dans ce cas, la flamme s'est éteinte durant le fonctionnement du brûleur. Dans certains cas moins fréquents, il existe plusieurs causes de défauts engendrant alors l'affichage de plusieurs séries d'impulsions lumineuses différentes. L'appel d'affichage de la (des) série(s) d'impulsions peut être répété à volonté en appuyant sur le bouton comme décrit ci-dessus. Cependant, un actionnement du bouton pendant une durée inférieure à 3 secondes, ne déclenche aucun affichage de défaut, mais un redémarrage de l'installation de chauffe.An exemplary embodiment of the method according to the invention is given below: as soon as a disturbance occurs in a heating installation, the supply to the fuel is immediately cut off, which is signaled by a continuous signal resulting in the uninterrupted lighting of two light-emitting diodes. Pressing a button for at least 3 seconds erases the continuous signal and triggers the emission of a series of light pulses of duration equal attributed to the type of disturbance. In the present description, a series of light pulses can be synonymous with a single light pulse. In a heating installation comprising a blower burner, i.e. a closed combustion chamber, a single light pulse means that a pressure switch signaled a fault before the blower started and that a disturbance therefore occurred. Another example of the meaning of a series of light pulses is that of a series of six light pulses. In this case, the flame went out during the burner operation. In some cases less frequent, there are several causes of faults thus generating the display of several different series of light pulses. The display call of the series of pulses can be repeated at will by pressing the button as described above. However, pressing the button for a period of time less than 3 seconds, does not trigger any fault display, but a restart of the heating system.

Selon l'une des variantes du procédé conforme à l'invention, les signaux optiques apparaissant sur l'afficheur optique sont remplacés ou complétés par des signaux sonores générés par une source de sons.According to one of the variants of the method according to the invention, the signals optics appearing on the optical display are replaced or supplemented by sound signals generated by a sound source.

Le dispositif selon l'invention comprend un microprocesseur pour détecter l'apparition d'une perturbation et le type de perturbation, et au moins une mémoire de données pour enregistrer les données relatives à un signal attribué au type de la perturbation, sachant que le microprocesseur peut activer un afficheur optique à l'aide du signal correspondant aux données. La préférence est donnée à une variante du dispositif selon laquelle le signal est constitué d'une série d'impulsions attribuée au type de la perturbation concernée qui peut être transformée en une série d'impulsions lumineuses au niveau de l'afficheur optique. La mémoire de données peut être un composant de mémoire utilisé couramment en microélectronique, ou il peut être également intégré dans le microprocesseur. La mémoire de données peut éventuellement être sujette à l'application d'une tension d'alimentation.The device according to the invention comprises a microprocessor for detecting the appearance of a disturbance and the type of disturbance, and at least one memory to record data relating to a signal assigned to the type of the disturbance, knowing that the microprocessor can activate an optical display at using the signal corresponding to the data. Preference is given to a variant of the device according to which the signal consists of a series of pulses attributed to the type of disturbance concerned which can be transformed into a series of light pulses at the optical display. The memory of data can be a memory component commonly used in microelectronics, or it can also be integrated into the microprocessor. Memory data may possibly be subject to the application of a voltage feed.

Selon une autre variante, le dispositif comporte un transistor permettant d'activer l'afficheur optique à partir du microprocesseur. Le microprocesseur et le transistor ou le transistor et l'afficheur optique peuvent être reliés entre eux, par exemple, au moyen de câbles électriques et autres composants électriques tels que des résistances électriques ou des circuits intégrés.According to another variant, the device comprises a transistor allowing activate the optical display from the microprocessor. The microprocessor and the transistor or the transistor and the optical display can be linked together, by example, using electrical cables and other electrical components such as electrical resistors or integrated circuits.

Suivant une variante favorable du dispositif selon l'invention, l'afficheur optique possède une ou plusieurs diodes électroluminescentes, rouges de préférence. une variante préférée comporte un bouton permettant l'appel d'affichage du signal attribué au type de la perturbation. Il est alors particulièrement préférable que le bouton et l'afficheur optique soient intégrés ensemble dans un composant électrique.According to a favorable variant of the device according to the invention, the display optic has one or more light-emitting diodes, red of preference. a preferred variant includes a button allowing the display call of the signal assigned to the type of disturbance. It is therefore particularly preferable that the button and the optical display are integrated together in a component electric.

L'un des avantages de l'invention réside dans l'utilisation d'un microprocesseur permettant de détecter l'apparition et le type d'une perturbation. Un microprocesseur est peu encombrant et, à condition de prévoir un refroidissement suffisant, fonctionne de manière fiable et notamment en régime continu.One of the advantages of the invention lies in the use of a microprocessor for detecting the appearance and type of a disturbance. A microprocessor is space-saving and, provided that cooling is provided sufficient, works reliably and especially in continuous operation.

Il est possible d'utiliser plusieurs afficheurs optiques pour la signalisation optique. Ainsi, les diverses causes de perturbation peuvent être signalées, par exemple, au moyen de signaux lumineux de couleurs ou combinaisons de couleurs différentes. Il est en outre possible de signaler la présence d'une perturbation par un signal lumineux d'un moyen lumineux et la cause de la perturbation par un signal lumineux d'un second moyen lumineux. Dans l'intérêt d'un encombrement réduit, on utilise à cet effet des diodes électroluminescentes, éventuellement de couleur différente.It is possible to use several optical displays for signaling optical. Thus, the various causes of disturbance can be signaled, by example, by means of color light signals or color combinations different. It is also possible to signal the presence of a disturbance by a light signal of a light means and the cause of the disturbance by a signal light of a second light means. In the interest of reduced dimensions, we uses light-emitting diodes for this purpose, possibly colored different.

Pour une meilleure compréhension, une variante de réalisation du dispositif selon l'invention est décrite ci-dessous à l'aide du dessin, sachant que l'exemple de réalisation représenté ne se limite pas à l'invention. Les diverses figures du dessin montrent :

Fig. 1:

Fig. 2:
une variante de réalisation du dispositif selon l'invention.
For a better understanding, an alternative embodiment of the device according to the invention is described below with the help of the drawing, knowing that the embodiment shown is not limited to the invention. The various figures in the drawing show:
Fig. 1:
a heating installation, and
Fig. 2:
an alternative embodiment of the device according to the invention.

La figure 1 montre une installation de chauffe 2 comportant un brûleur 3 et un dispositif pour la signalisation optique des perturbations d'une installation de chauffe 2. Ces perturbations s'expriment notamment par un arrêt indésirable de l'installation de chauffe2. Le dispositif 1 possède une ou plusieurs diodes électroluminescentes 5 connectées en parallèle. La figure 2 représente une vue en perspective agrandie du dispositif 1. Pour une meilleure compréhension, la vue est schématisée et largement simplifiée. Dans le boítier 10 est disposé un microprocesseur 4 qui contrôle le fonctionnement du brûleur 3 et déclenche, dès l'apparition d'une perturbation, l'allumage ininterrompu d'une diode électroluminescente 5 intégrée dans le bouton 7. A cet effet, le microprocesseur 4 active la diode électroluminescente 5 par l'intermédiaire du transistor 6. La fermeture du contact électrique ouvert 11 représenté dans le bouton 7, déclenche un signal de commande faisant que le microprocesseur 4 coupe l'éclairage ininterrompu de la diode électroluminescente 5 et l'active de telle façon que ladite diode électroluminescente 5 émette un nombre d'impulsions lumineuses caractérisant le type de la perturbation. Pendant que l'électrode électroluminescente 5 est allumée de façon ininterrompue, l'information concernant le type de la perturbation est stockée dans la mémoire de données 8. En fonction de cette information, le microprocesseur 4 ayant reçu le signal de commande, définit le nombre d'impulsions à émettre. Le microprocesseur 4 est relié au transistor par l'intermédiaire d'une ligne électrique 9, ledit transistor étant relié à la diode électroluminescente 5 par l'intermédiaire d'une autre ligne électrique 9. La figure 2 montre en outre des lignes électriques 9 entre le microprocesseur 4 et le contact électrique de fermeture incorporé dans le composant du bouton 7, ainsi qu'entre le microprocesseur 4 et la mémoire de données 8. Le terme de ligne électrique employé ici sous-entend également une chaíne de liaisons électriques partielles comportant d'autres composants électriques interconnectés.Figure 1 shows a heating installation 2 comprising a burner 3 and a device for the optical signaling of disturbances of a heats 2. These disturbances are expressed in particular by an undesirable stopping of the heating system 2. Device 1 has one or more diodes 5 LEDs connected in parallel. Figure 2 shows a view in enlarged perspective of the device 1. For a better understanding, the view is schematized and largely simplified. In the housing 10 is disposed a microprocessor 4 which controls the operation of the burner 3 and triggers, as soon as the appearance of a disturbance, the uninterrupted lighting of a diode light-emitting 5 integrated in the button 7. For this purpose, the microprocessor 4 activates the light-emitting diode 5 via the transistor 6. The closure of the open electrical contact 11 shown in button 7, triggers a signal control causing the microprocessor 4 to cut off the uninterrupted lighting of the light-emitting diode 5 and activates it in such a way that said diode 5 emits a number of light pulses characterizing the type of disturbance. While the electroluminescent electrode 5 is on information about the type of disturbance is continuously stored in the data memory 8. Based on this information, the microprocessor 4 having received the control signal, defines the number of pulses to emit. The microprocessor 4 is connected to the transistor via a line electric 9, said transistor being connected to the light-emitting diode 5 by through another power line 9. Figure 2 further shows lines 9 between the microprocessor 4 and the electric closing contact incorporated in the component of the button 7, as well as between the microprocessor 4 and the data memory 8. The term power line used here means also a chain of partial electrical connections comprising other interconnected electrical components.

Grâce à l'utilisation de composants électroniques peu sujets à l'usure que l'on fabrique aujourd'hui en grande série et à un prix unitaire réduit, le dispositif selon l'invention permet, dès l'intervention d'une perturbation fonctionnelle, l'affichage fiable de l'apparition et du type de perturbation d'une installation de chauffe ou d'une partie de cette installation.Thanks to the use of electronic components which are not subject to much wear today we manufacture in large series and at a reduced unit price, the device according to the invention allows, upon the intervention of a functional disturbance, reliable display of the appearance and type of disturbance of a heating or part of this installation.
