Description

DISPOSITIF DE CONTROLE ET DE GESTION DE L'APPROVISIONNEMENTSUPPLY MONITORING AND MANAGEMENT DEVICE
ET DE LA DISTRIBUTION DE CARBURANTSAND THE DISTRIBUTION OF FUELS
DANS LES STATIONS-SERVICEIN SERVICE STATIONS
La présente invention a pour objet un dispositif de contrôle et de gestion de l'approvisionnement et de la distribution de carburants dans les stations-service.The present invention relates to a device for controlling and managing the supply and distribution of fuels in service stations.
Une station-service distribuant des carburants comprend un certain nombre de cuves de stockage, compartimentées ou non, dans chacune desquelles est destiné à être stocké un type de carburant. Ces cuves de stockage sont remplies à partir de citernes de livraison acheminées généralement par route, par l'intermédiaire de camions-citernes. La distribution des carburants est réalisée à l'aide de pompes de distribution qui sont équipées chacune d'un compteur fournissant à la fois le volume délivré et le prix à payer par le client en fonction d'un prix au litre prédéterminé. II existe aujourd'hui une grande incertitude sur les volumes réellement réceptionnés dans les stations-service et réellement vendus, ce qui implique également une grande incertitude quant à la rentabilité d'une station-service ainsi qu'à la possibilité de fixer de façon objective le prix du litre de chaque carburant pour que la station-service bénéficie d'une rentabilité contrôlée. II faut en effet considérer que les carburants sont des produits très sensibles à la variation de température, cette sensibilité se traduisant par un changement de volume en fonction des changements de température. Le volume augmente en même temps que la température et diminue en même temps que la température. Il existe une température légale ou température de référence qui est la valeur à laquelle les douanes valident les quantités à la sortie des raffineries et des dépôts pétroliers et appliquent les différentes taxes sur les volumes vendus aux stations-service. Cette température est de 15°C.A service station distributing fuels comprises a certain number of storage tanks, compartmentalized or not, in each of which is intended to be stored a type of fuel. These storage tanks are filled from delivery tanks generally transported by road, via tankers. The distribution of fuels is carried out using distribution pumps which are each equipped with a meter providing both the volume delivered and the price to be paid by the customer according to a predetermined price per liter. Today there is great uncertainty about the volumes actually received at service stations and actually sold, which also implies great uncertainty as to the profitability of a service station as well as the possibility of fixing in an objective manner the price of a liter of each fuel so that the service station benefits from controlled profitability. It must indeed be considered that fuels are products very sensitive to temperature variation, this sensitivity translating into a change in volume as a function of temperature changes. The volume increases with the temperature and decreases with the temperature. There is a legal temperature or reference temperature which is the value at which customs validate the quantities leaving refineries and petroleum depots and apply the various taxes on the volumes sold at service stations. This temperature is 15 ° C.
Aujourd'hui, lorsqu'un camion-citerne se présente à une station- service pour livrer du carburant, plusieurs cas se présentent. Suivant une possibilité très fréquente, le contenu du camion et son volume ne sont pas du tout contrôlés.Today, when a tanker truck arrives at a service station to deliver fuel, several cases arise. According to a very frequent possibility, the contents of the truck and its volume are not at all controlled.
Suivant une autre possibilité, le contenu est contrôlé par sabrage des cuves, c'est-à-dire une mesure approximative des volumes devant être livrés.According to another possibility, the content is controlled by saberage of the tanks, that is to say an approximate measurement of the volumes to be delivered.
Suivant une autre possibilité, le contenu du camion n'est pas directement contrôlé, aucune mesure n'étant effectuée sur le camion lui- même. La station est alors équipée de jauges électroniques de niveau dans les cuves. Toutefois, la distribution du carburant auprès des clients ne s'arrêtant pas, et compte tenu des remous à l'intérieur de la cuve dus à la livraison, il n'est pas possible de déterminer de façon précise quel est le volume transféré d'une citerne de livraison à une cuve de stockage.According to another possibility, the content of the truck is not directly controlled, no measurement being carried out on the truck itself. even. The station is then equipped with electronic level gauges in the tanks. However, since the distribution of fuel to customers does not stop, and given the backwash inside the tank due to delivery, it is not possible to determine precisely what volume is transferred from a delivery tank to a storage tank.
En outre, les températures de livraison ne sont pas prises en compte, et la reprise des gaz qui sont transférés de la cuve de stockage vers la citerne de livraison du camion, lors du transfert du carburant de la citerne vers la cuve de stockage, n'est également pas prise en compte. Dans le futur, pour des raisons de sécurité et de lutte contre la pollution, il ne sera bientôt plus possible de procéder à une mesure de la quantité de carburant contenu dans une citerne de livraison par ouverture de la citerne et jaugeage de celle-ci par sabrage, et il ne sera plus possible de jauger de la même façon les cuves de stockage de la station. Cela posera donc le problème d'un contrôle contradictoire entre le livreur et le réceptionnaire pour les volumes de carburant livrés, ainsi que pour le jaugeage des cuves de la station pour le contrôle des stocks et la passation des commandes.In addition, delivery temperatures are not taken into account, and the recovery of gases that are transferred from the storage tank to the delivery tank of the truck, during the transfer of fuel from the tank to the storage tank, n is also not taken into account. In the future, for safety and pollution control reasons, it will soon no longer be possible to measure the quantity of fuel contained in a delivery tank by opening the tank and gauging it by saberage, and it will no longer be possible to gauge the station's storage tanks in the same way. This will therefore pose the problem of a contradictory control between the delivery man and the receiver for the volumes of fuel delivered, as well as for the gauging of the tanks of the station for the control of stocks and the placing of orders.
Le but de l'invention est de fournir un dispositif de contrôle et de gestion de l'approvisionnement et de la distribution de carburant, qui soit de structure simple et d'utilisation simple pour le gérant ou l'employé de la station-service, et qui permette de parfaitement contrôler les quantités de carburant livrées ainsi que les quantités de carburant vendues en vue de réaliser une gestion rigoureuse de la station-service.The object of the invention is to provide a device for controlling and managing the supply and distribution of fuel, which is simple in structure and simple to use for the manager or employee of the service station, and which makes it possible to perfectly control the quantities of fuel delivered as well as the quantities of fuel sold with a view to achieving rigorous management of the service station.
A cet effet, le dispositif qu'elle concerne, comprenant au moins une cuve de stockage pour chaque carburant, dans laquelle débouchent, d'une part, un conduit de remplissage pouvant être relié à une citerne de livraison et, d'autre part, un conduit de prélèvement amenant le carburant à un poste de distribution équipé d'un dispositif de mesure volumétrique du carburant, lui-même relié à un pupitre de station, est caractérisé en ce qu'il comporte :To this end, the device it relates to, comprising at least one storage tank for each fuel, into which, on the one hand, a filling duct which can be connected to a delivery tank and, on the other hand, a sampling line bringing the fuel to a distribution station equipped with a volumetric fuel measurement device, itself connected to a station console, is characterized in that it comprises:
- un débitmètre monté sur chaque conduit de remplissage,- a flow meter mounted on each filling pipe,
- une sonde de température montée sur chaque conduit de remplissage,- a temperature probe mounted on each filling pipe,
- une sonde de température disposée dans chaque cuve de stockage, ces différents éléments de mesure, ainsi que chaque dispositif de mesure volumétrique du carburant distribué, étant reliés à un calculateur, dans lequel les informations reçues sont traitées par des programmes informatiques déterminant pour les carburants livrés, le volume de carburant ramené à la température légale en tenant compte du volume livré et mesuré et de la température des carburants livrés et, pour les carburants vendus, le volume ramené à la température légale en tenant compte du volume distribué et de la température à l'intérieur de chaque cuve de stockage. En outre, le logiciel, après calcul du volume livré de chaque carburant et ramené à la température légale, commande l'édition d'un bordereau comportant au moins l'indication du volume de carburant ramené à la température légale.- a temperature probe placed in each storage tank, these various measurement elements, as well as each volumetric measurement device for the fuel distributed, being connected to a computer, in which the information received is processed by computer programs determining for the fuels delivered, the volume of fuel brought back to the legal temperature in taking into account the volume delivered and measured and the temperature of the fuels delivered and, for the fuels sold, the volume brought back to the legal temperature taking into account the volume distributed and the temperature inside each storage tank. In addition, the software, after calculating the volume delivered of each fuel and brought back to the legal temperature, orders the edition of a slip comprising at least the indication of the volume of fuel brought back to the legal temperature.
Avantageusement, le logiciel tient compte dans ses calculs des incertitudes sur les valeurs mesurées, en fonction des performances des différents instruments de mesure.Advantageously, the software takes into account in its calculations the uncertainties on the measured values, as a function of the performance of the various measuring instruments.
Lors d'une livraison, le débitmètre monté sur le conduit de remplissage d'une cuve mesure le débit transféré de la citerne de la livraison vers la cuve de stockage considérée. La sonde de température mesure quelle est la température réelle du carburant livré. Ces informations sont transférées à l'ordinateur. L'ordinateur dispose d'une base de données fournissant les coefficients de dilatation et de rétraction des différents carburants.During a delivery, the flow meter mounted on the filling pipe of a tank measures the flow transferred from the delivery tank to the storage tank in question. The temperature sensor measures the actual temperature of the fuel delivered. This information is transferred to the computer. The computer has a database providing the coefficients of expansion and retraction of the different fuels.
Le logiciel compare la température de livraison à la température légale de 1 5°C. De cette valeur est retranchée l'incertitude absolue des sondes de température, par exemple 0,5°C.The software compares the delivery temperature with the legal temperature of 15 ° C. This value is subtracted from the absolute uncertainty of the temperature probes, for example 0.5 ° C.
Si la température du carburant livré est de 25,8°C, il est procédé à la soustraction à cette valeur de 1 5°C, ce qui donne une différence de 10,8°C. C'est de cette valeur qu'est retranchée l'incertitude sur la mesure des sondes de température, soit 0,5 °C, ce qui permet d'obtenir un écart de température de 1 0,3°C. A supposer que la base de données des coefficients de dilatation soit incrémentée de 0,25° en 0,25 °, la température retenue pour les calculs sera donc de 10,25 °C. Le logiciel cherche le coefficient correspondant dans la base de données et applique ce coefficient sur le volume mesuré pour obtenir le volume légal à 1 5°C. A la fin de la livraison, le logiciel édite un bordereau de réception, par exemple en triple exemplaire, qui est cosigné par le livreur et par le réceptionnaire, le livreur récupérant un des exemplaires du bordereau. Sur ce bordereau figure notamment le volume ramené à 1 5 °C. C'est sur cette base que sera effectué le paiement du carburant par la station-service à la raffinerie qui a effectué la livraison.If the temperature of the fuel delivered is 25.8 ° C, this value is subtracted from 15 ° C, which gives a difference of 10.8 ° C. It is from this value that the uncertainty on the measurement of the temperature probes is subtracted, ie 0.5 ° C, which allows a temperature difference of 1 0.3 ° C to be obtained. Assuming that the expansion coefficients database is incremented by 0.25 ° into 0.25 °, the temperature used for the calculations will therefore be 10.25 ° C. The software searches the corresponding coefficient in the database and applies this coefficient to the volume measured to obtain the legal volume at 1 5 ° C. At the end of the delivery, the software publishes a receipt slip, for example in triplicate, which is co-signed by the delivery man and by the receiver, the delivery man retrieving one of the copies of the slip. On this slip appears in particular the volume reduced to 1 5 ° C. It is on this basis that payment for fuel will be made by the service station at the refinery that made the delivery.
Le logiciel dispose d'un programme permettant de récapituler les livraisons :The software has a program for summarizing deliveries:
- sur une période de date à date sur l'ensemble des fournisseurs, et- over a period from date to date across all suppliers, and
- sur une période de date à date par fournisseur.- over a period from date to date by supplier.
Ce récapitulatif est effectué carburant par carburant. En outre, le logiciel calcule le volume de carburant renvoyé sous forme gazeuse à la citerne de livraison, et déduit ce volume du volume de carburant mesuré lors du passage dans un conduit de remplissage.This summary is done fuel by fuel. In addition, the software calculates the volume of fuel returned in gaseous form to the delivery tank, and deduces this volume from the volume of fuel measured when passing through a filling duct.
Lorsqu'une cuve de stockage se remplit en carburant, il faut évacuer de celle-ci le gaz qu'elle contient. Ce gaz est renvoyé dans la citerne de livraison. Or, ce gaz contient des particules de carburant qui, normalement, ne sont prises en compte ni par le livreur, ni par le réceptionnaire. Le dispositif selon l'invention permet de calculer, en fonction du volume de carburant livré, le volume de carburant renvoyé dans la citerne de livraison par la masse gazeuse, et déduit ce volume résultant de la masse gazeuse du volume livré réellement, pour refléter de façon exacte la valeur du volume livré. Suivant une autre caractéristique de l'invention, pour déterminer la température du carburant distribué, la sonde thermique disposée dans la cuve fournit, à intervalles réguliers, la température mesurée au logiciel qui calcule une température moyenne sur un intervalle de temps déterminé, cette température moyenne étant utilisée par le logiciel pour calculer le volume distribué ramené à la température légale.When a storage tank fills with fuel, the gas it contains must be removed from it. This gas is returned to the delivery tank. However, this gas contains fuel particles which, normally, are not taken into account either by the delivery person or by the receiver. The device according to the invention makes it possible to calculate, as a function of the volume of fuel delivered, the volume of fuel returned to the delivery tank by the gas mass, and deducts this volume resulting from the gas mass from the volume actually delivered, to reflect exactly the value of the volume delivered. According to another characteristic of the invention, to determine the temperature of the fuel dispensed, the thermal probe placed in the tank provides, at regular intervals, the temperature measured to the software which calculates an average temperature over a determined time interval, this average temperature being used by the software to calculate the volume distributed brought back to the legal temperature.
Chaque cuve de stockage dispose d'une sonde thermique pilotée par le logiciel. Cette sonde peut, par exemple, mesurer la température du carburant contenu dans la cuve considérée toutes les trente minutes. Le logiciel calcule sur un intervalle de temps déterminé, par exemple de 24 heures moins quelques minutes, la température moyenne de chaque cuve. Ce relevé peut être fait juste avant l'ouverture de la station.Each storage tank has a thermal probe controlled by software. This probe can, for example, measure the temperature of the fuel contained in the tank in question every thirty minutes. The software calculates over a determined time interval, for example 24 hours minus a few minutes, the average temperature of each tank. This reading can be done just before the station opens.
Sur cette période de temps, les volumes réels distribués par les différentes pompes ont été transmis à l'ordinateur. Le logiciel, considérant le volume de chaque carburant distribué au cours d'une période et la température moyenne du carburant au cours de cette période, calcule le volume distribué ramené à 15°C, qui est la température légale actuelle.Over this period of time, the actual volumes distributed by the various pumps were transmitted to the computer. The software, considering the volume of each fuel dispensed during a period and the average fuel temperature during this period, calculates the dispensed volume reduced to 15 ° C, which is the current legal temperature.
Si la température moyenne est supérieure à 15°C, le volume vendu sera inférieur au volume à 15°C et il y aura gain pour la station- service, si au contraire la température moyenne du carburant vendu est inférieure à 15°C, le volume vendu, ramené à 15°C, sera supérieur au volume réel et il y aura perte pour la station-service. Il est donc possible de calculer les gains et les pertes sur une journée et carburant par carburant, et d'éditer un rapport à la journée ou un rapport sur une période de date à date.If the average temperature is above 15 ° C, the volume sold will be less than the volume at 15 ° C and there will be a gain for the service station, if on the contrary the average temperature of the fuel sold is less than 15 ° C, the volume sold, brought to 15 ° C, will be greater than the actual volume and there will be loss for the service station. It is therefore possible to calculate gains and losses on a day and fuel by fuel, and to edit a day report or a report on a period from date to date.
Cela permet au commerçant d'ajuster le prix de vente du carburant pour tenir compte des différentes variations de volume dans un sens d'augmentation ou dans un sens de diminution par rapport au volume vendu rapporté à 15°C, pour tenir compte desdites variations. Suivant une forme d'exécution de ce dispositif, chaque cuve est équipée de jauges électroniques de mesure de niveau reliées à l'ordinateur et fournissant le volume stocké, à tout instant, le logiciel de traitement permettant :This allows the merchant to adjust the selling price of the fuel to take into account the different volume variations in an increasing direction or in a decreasing direction compared to the sold volume reported at 15 ° C, to take into account said variations. According to one embodiment of this device, each tank is equipped with electronic level measurement gauges connected to the computer and providing the volume stored, at all times, the processing software allowing:
- de calculer le stock théorique à la température de livraison, - de calculer le stock théorique à la température légale de 15°C, et de mesurer les écarts entre :- calculate the theoretical stock at the delivery temperature, - calculate the theoretical stock at the legal temperature of 15 ° C, and measure the differences between:
- le stock théorique à la température de livraison et le stock théorique à la température légale,- theoretical stock at delivery temperature and theoretical stock at legal temperature,
- le stock théorique à la température de livraison et le stock mesuré par les sondes,- the theoretical stock at delivery temperature and the stock measured by the probes,
- le stock théorique à la température légale et le stock mesuré par les sondes.- the theoretical stock at legal temperature and the stock measured by the probes.
Il doit être noté que le stock de départ dans chaque cuve est initialisé lors de l'installation du logiciel, les différentes livraisons étant renseignées lorsqu'elles ont lieu. Il peut être également noté que, dans cette dernière forme d'exécution, il est possible de disposer de renseignements complémentaires, par rapport à la solution précédente, ne mettant pas en oeuvre des jauges de mesure de niveau. Ces renseignements complémentaires permettent d'affiner encore la gestion de la station- service.It should be noted that the starting stock in each tank is initialized during the installation of the software, the various deliveries being indicated when they take place. It may also be noted that, in this latter embodiment, it is possible to have additional information, compared to the previous solution, not using level measurement gauges. This additional information further refines the management of the service station.
Il doit être noté que le pupitre de station peut être le pupitre d'encaissement, qui est associé à un ordinateur assurant localement les différents traitements définis précédemment, s'il s'agit d'une station service autonome.It should be noted that the station console can be the collection console, which is associated with a computer locally providing the various treatments defined above, if it is an autonomous service station.
Il est également possible d'envisager le cas d'une station en libre service, pour laquelle la gestion est effectuée de façon centralisée et délocalisée.It is also possible to consider the case of a self-service station, for which management is carried out in a centralized and delocalized manner.
Dans ce cas, le pupitre de station comprend des modules d'acquisition des données avec mémoires et des éléments de transmission par ligne téléphonique vers un centre de gestion équipé d'un ordinateur destiné au stockage, à l'analyse et/ou au traitement des informations reçues.In this case, the station console includes data acquisition modules with memories and elements for transmission by telephone line to a management center equipped with a computer intended for the storage, analysis and / or processing of information received.
Il est alors possible d'envisager le traitement de certaines informations sur place à l'aide d'un ordinateur local, avec transfert des informations traitées, ou de transférer les informations de base, c'est-à-dire les valeurs mesurées à l'ordinateur central qui en assure le traitement.It is then possible to envisage the processing of certain information on the spot using a local computer, with transfer of the processed information, or to transfer the basic information, that is to say the values measured at the central computer which handles it.
De préférence, les sondes et les jauges sont électroniques afin de disposer directement d'informations sous forme numérique dont le transport par voie télématique est aisé.Preferably, the probes and gauges are electronic in order to directly have information in digital form whose transport by telematic means is easy.
De toute façon, l'invention sera bien comprise à l'aide de la description qui suit, en référence au dessin schématique annexé dont la figure unique représente les principaux composants constitutifs de ce dispositif. La figure unique représente une cuve de stockage 2 d'un carburant, dans laquelle débouchent, d'une part, un conduit 3 de remplissage pouvant être relié, par des moyens non représentés, à une citerne de livraison 4 et, d'autre part, un conduit 5 de prélèvement amenant le carburant à un poste de distribution 6 équipé d'un dispositif de mesure volumétrique du carburant, lui-même relié à un pupitre d'encaissement 7. A ce pupitre d'encaissement 7 est associé un ordinateur 8. Suivant la caractéristique essentielle de l'invention, ce dispositif comporte un débitmètre 9 monté sur le conduit de remplissage 3 ainsi qu'une sonde de température 10 montée sur ce même conduit. Ces éléments de mesure 9 et 10 fournissent des informations à l'ordinateur 8. Il est prévu une sonde de température 12 à l'intérieur de la cuve de stockage 2, ainsi qu'une jauge électronique de mesure 13 destinée à déterminer le niveau de carburant à l'intérieur de cette même cuve. Ces informations sont également transmises à l'ordinateur 8, et traitées de la façon indiquée précédemment. Un conduit 14 ramène les gaz contenus dans la cuve de stockage 2 vers la citerne 4, au fur et à mesure de la livraison de carburant.In any case, the invention will be clearly understood with the aid of the description which follows, with reference to the appended schematic drawing, the single figure of which represents the main constituent components of this device. The single figure shows a fuel storage tank 2, into which open, on the one hand, a filling conduit 3 which can be connected, by means not shown, to a delivery tank 4 and, on the other hand , a sampling line 5 bringing the fuel to a distribution station 6 equipped with a volumetric fuel measurement device, itself connected to a collection desk 7. A computer 8 is associated with this collection desk 7. According to the essential characteristic of the invention, this device comprises a flow meter 9 mounted on the filling pipe 3 as well as a temperature probe 10 mounted on this same pipe. These measurement elements 9 and 10 provide information to the computer 8. There is a temperature probe 12 inside the storage tank 2, as well as an electronic measurement gauge 13 intended to determine the level of fuel inside this same tank. This information is also transmitted to the computer 8, and processed in the manner indicated above. A conduit 14 returns the gases contained in the storage tank 2 to the tank 4, as fuel is delivered.
Comme il ressort de ce qui précède, l'invention apporte une grande amélioration à la technique existante en fournissant un dispositif permettant à l'aide de quelques éléments de mesure, de volume, de température et de niveau, et d'un ordinateur associé à un logiciel adapté, de procéder à un contrôle rigoureux des quantités de carburant réceptionnées et des quantités distribuées, en tenant compte des variations de volume résultant de la température, pour effectuer une gestion économique et rigoureuse de la station-service.As is apparent from the above, the invention brings a great improvement to the existing technique by providing a device making it possible, using a few measurement elements, volume, temperature and level, and a computer associated with an adapted software, to carry out a rigorous control of the quantities of fuel received and the quantities distributed, taking into account the variations in volume resulting from the temperature, to carry out an economic and rigorous management of the service station.
Comme il va de soi, l'invention ne se limite pas à la seule forme d'exécution de ce dispositif, décrite ci-dessus à titre d'exemple, elle en embrasse au contraire toutes les variantes. C'est ainsi notamment que la cuve de stockage pourrait ne pas comporter de dispositif de mesure du volume du carburant, que le même ordinateur pourrait être relié à différentes cuves contenant différents carburants, ou encore que les informations pourraient être transmises à un ordinateur situé à distance, sans que l'on sorte pour autant du cadre de l'invention. As it goes without saying, the invention is not limited to the sole embodiment of this device, described above by way of example, on the contrary it embraces all variants. Thus, in particular, the storage tank could not include a device for measuring the volume of fuel, the same computer could be connected to different tanks containing different fuels, or that the information could be transmitted to a computer located at distance, without departing from the scope of the invention.
