Abstract
Description
Die Erfindung betrifft ein Verfahren zur Ermittlung der durch den Zapfschlauch einer Zapfstelle abgegebenen Menge eines Kraftstoffes, insbesondere eines bleifreien flüssigen Kraftstoffes zum Betrieb von Verbrennungsmotoren, wobei der Kraftstoff mittels einer Pumpe aus einem Vorratsbehälter gefördert und über ein der Pumpe im Kraftstofffluß nachgeschaltetes Meßwerk dem mit einem Zapfventil versehenen Zapfschlauch zugeführt wird und nach Start des Zapfvorganges durch das Meßwerk Meßwerte zur Messung der abgegebenen Kraftstoffmenge erzeugt werden, die mittels eines Rechners zur Ermittlung und Anzeige sowohl der abgegebenen Menge als auch des sich hieraus ergebenden Preises herangezogen werden (siehe etwa EP 0 431 208 A).The invention relates to a method for determining the through the dispensing hose a fuel dispensed amount, in particular one unleaded liquid fuel for the operation of internal combustion engines, wherein the fuel is pumped out of a reservoir by means of a pump and via a measuring unit connected downstream of the pump in the fuel flow a nozzle is provided and after the start of the Tapping process by the measuring mechanism measured values for measuring the output Amount of fuel generated using a calculator to determine and display both the quantity delivered and the resulting quantity resulting price can be used (see for example EP 0 431 208 A).
Bei den derzeit auf dem Markt befindlichen Zapfstellen ist das komplette Flüssigkeitssystem einschließlich des Zapfschlauches bis zum Zapfventil gefüllt. Beim Herausnehmen des Zapfventils aus seiner Halterung wird der Pumpenmotor eingeschaltet. Unmittelbar nach dem Öffnen des Zapfventils tritt demzufolge der im Zapfschlauch befindliche Kraftstoff aus, wobei die durch das Meßwerk fließende Kraftstoffmenge mit Hilfe eines Impulsgebers ermittelt wird, der vom Meßwerk, vorzugsweise einem Kolbenmesser, angetrieben wird. Diese Impulse werden mittels eines Rechners zur Ermittlung und Anzeige der abgegebenen Menge und des sich hieraus ergebenden Preises verarbeitet.This is complete with the taps currently on the market Liquid system including the nozzle up to the nozzle filled. When the nozzle is removed from its holder, the Pump motor switched on. Immediately after opening the nozzle valve occurs consequently the fuel in the dispensing hose, the through the metering quantity of fuel flowing is determined with the help of a pulse generator is driven by the measuring mechanism, preferably a piston knife becomes. These impulses are calculated and displayed using a computer the quantity delivered and the resulting price processed.
Die Zapfschläuche der derzeit auf dem Markt befindlichen Zapfstellen werden an der Zapfstelle aufgerollt oder zumindest beim Zurückhängen verlagert oder eingelegt. Dabei wird der Schlauch geringfügig gewalkt und es kommt zu geringen Volumenänderungen, welche vom Meßwerk registriert werden. Insbesondere je näher der Impulsgeber vor der nächstfolgenden Impulsflanke steht, kommt es zu einer Veränderung der gemessenen und angezeigten Menge und des sich hieraus ergebenden Preises. Im hydraulischen Bereich des Meßwerkes ist diese Erscheinung kaum abzustellen, da das bewegte Volumen, das diesen letzten Impuls auslöst, extrem gering ist. Für die Bedienpersonen zeigt sich dieser Vorgang durch eine Veränderung des ermittelten Preises nach dem Abschluß des eigentlichen Betankungsvorganges. Die Bedienpersonen empfinden diesen Vorgang immer dann besonders störend, wenn die Tankung möglichst genau auf einem vorbestimmten Betrag beendet werden sollte, und dieser sich dann geringfügig verändert.The dispensing hoses of the dispensing points currently on the market will be rolled up at the tap or at least shifted when hanging back or inserted. The hose is slightly tumbled and it comes to small volume changes, which are registered by the measuring mechanism. In particular, the closer the pulse generator is to the next pulse edge stands, there is a change in the measured and displayed Quantity and the resulting price. In the hydraulic area of the This phenomenon can hardly be stopped by the measuring unit, since the moving volume, that triggers this last impulse is extremely low. For the operators this process is shown by a change in the determined price the completion of the actual refueling process. The operators find this process particularly annoying when refueling should be terminated as precisely as possible to a predetermined amount, and this then changes slightly.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren der eingangs beschriebenen Art zum Messen der durch den Zapfschlauch einer Zapfstelle abgegebenen Menge eines Kraftstoffes zu schaffen, das eine Kompensation derartiger Differenzen ohne konstruktive Änderungen der vorhandenen Zapfstellenkonstruktion auf einfache Weise ermöglicht.The invention has for its object a method of the beginning described type for measuring the through the nozzle of a tap dispensed amount of a fuel to create a compensation such differences without constructive changes to the existing ones Tap construction made possible in a simple manner.
Die Lösung dieser Aufgabenstellung durch die Erfindung ist dadurch gekennzeichnet, daß nach einer Unterbrechung des Meßvorgangs innerhalb eines Zapfvorganges die ersten vom Meßwerk erzeugten Meßwerte erfaßt und mit einer vorgegebenen, programmierbaren Anzahl von Meßwerten verglichen werden, und die erfaßten Meßwerte nicht bei der Ermittlung und Anzeige von Menge und Preis berücksichtigt werden, wenn die vorgegebene Anzahl von Meßwerten nicht überschritten wird, jedoch die erfaßten Meßwerte in die Ermittlung und Anzeige von Menge und Preis unmittelbar einbezogen werden, wenn die vorgegebene Anzahl von Meßwerten überschritten wird.The solution to this problem by the invention is thereby characterized in that after an interruption of the measurement process within of a tapping process detects the first measured values generated by the measuring mechanism and compared with a predetermined, programmable number of measured values and the recorded measured values are not used when determining and displaying Quantity and price will be taken into account if the given number of Measured values are not exceeded, however, the measured values recorded in the Determination and display of quantity and price are directly involved, if the specified number of measured values is exceeded.
Bei dem erfindungsgemäßen Verfahren wird nach einer Unterbrechung des Meßvorganges, also wenn das Ventil während eines Zapfvorganges geschlossen wird, ein Überprüfungsmodus gestartet, welcher überprüft, wieviel Meßwerte nach der Unterbrechung erfaßt werden. Die Anzahl der erfaßten Meßwerte wird mit einer vorgegebenen, programmierbaren Anzahl von Meßwerten verglichen. Wird die vorgegebene Anzahl von Meßwerten nicht überschritten, werden die erfaßten Meßwerte nicht bei der Ermittlung und Anzeige von Menge und Preis berücksichtigt. Dies ist üblicherweise dann der Fall, wenn der Meßvorgang endgültig beendet wird, typischerweise durch Einhängen des Zapfventils, so daß die nach der Unterbrechung erfaßten Meßwerte praktisch gelöscht oder zumindest weder für die aktuelle Anzeige, noch für die Datenübertragung zu einer Fernanzeige und die Summierzähler berücksichtigt werden. Wird jedoch der Meßvorgang fortgesetzt, d. h., folgen den ersten erfaßten Meßwerten weitere Meßwerte, so daß die vorgegebene Anzahl der Meßwerte überschritten wird, so werden diese ersten Meßwerte unmittelbar mitgezählt und für die Ermittlung von Menge und Preis berücksichtigt.In the method according to the invention, after an interruption of the Measuring process, so if the valve during a dispensing process is closed, a review mode is started, which checks, how many measured values are recorded after the interruption. The number of Measured values are recorded with a predetermined, programmable number of measured values compared. Is the specified number of measured values If the measured values are not exceeded, they are not included in the determination and display of quantity and price are taken into account. This is usually then the case when the measuring process is finally ended, typically by Attach the nozzle so that those caught after the interruption Measured values practically deleted or at least neither for the current display, still for the data transmission to a remote display and the totalizer be taken into account. However, if the measuring process is continued, i. i.e., follow the first recorded measured values further measured values, so that the predetermined If the number of measured values is exceeded, these first measured values become counted immediately and for the determination of quantity and price considered.
Je nach Sensibilität des Meßwerkes ist es ausreichend, die Anzahl der vorgegebenen Meßwerte auf ein bis zwei Meßwerte zu beschränken. Grundsätzlich jedoch kann das Kompensationsverfahren, mit dem eine sogenannte Nachlaufunterdrückung realisiert wird, auch auf eine größere Anzahl von vorgegebenen Meßwerten angewendet werden.Depending on the sensitivity of the measuring mechanism, it is sufficient to determine the number of limit the specified measured values to one or two measured values. In principle, however, the compensation method with which one so-called overrun suppression is realized, even on a larger one Number of specified measured values can be used.
Gemäß einem vorteilhaften Vorschlag der Erfindung wird das Kompensationsverfahren zur Nachlaufunterdrückung in der oben beschriebenen Weise nur durchgeführt, wenn der Meßvorgang für eine Mindestzeitspanne unterbrochen wird. Es wird also eine programmierbare Zeitspanne vorgegeben, beispielsweise 1,5 bis 2 Sekunden, und nach der Unterbrechung des Meßvorganges wird die Zeit gemessen. Erst wenn die vorgegebene Zeitspanne überschritten wird, wird das Verfahren zur Erfassung und zum Vergleich von Meßwerten eingeleitet.According to an advantageous proposal of the invention Compensation method for overrun suppression in the above described manner only if the measuring process for a Minimum period of time is interrupted. So it becomes a programmable one Time period specified, for example 1.5 to 2 seconds, and after the Interrupting the measuring process, the time is measured. Only when that predetermined period of time is exceeded, the procedure for detection and initiated for the comparison of measured values.
Wird der Zapfvorgang endgültig beendet, beispielsweise durch Einhängen der Zapfpistole, wird das Programm wieder zurückgesetzt, so daß bei jedem Beginn eines Zapfvorganges das erfindungsgemäße Verfahren neu gestartet wird.If the tapping process is finally ended, for example by hanging the Nozzle, the program is reset, so that at each The method according to the invention was restarted at the start of a dispensing process becomes.
Das erfindungsgemäße Verfahren erfordert keine konstruktive oder apparative Änderung der bestehenden Zapfstellen, sondern kann durch Programmierung der vorhandenen Elektronik durchgeführt werden. Es ist demzufolge ohne größere Schwierigkeiten an vorhandenen Zapfstellen nachrüstbar. The method according to the invention does not require any design or equipment Modification of existing taps, but can be done through programming of the existing electronics. It is therefore without major difficulties can be retrofitted to existing taps.

Die in Fig. 1 schematisch dargestellte Zapfstelle zeigt einen Zapfmast 1, in
dem eine Rohrleitung 2 verlegt ist, an deren oberes Ende ein Zapfschlauch 3
angeschlossen ist. Dieser Zapfschlauch 3 ist über zwei Umlenkrollen 4
geführt, die ein Ausziehen des Zapfschlauches 3 aus dem Zapfmast 1
ermöglichen. Am Ende des Zapfschlauches 3 ist ein Zapfventil 5 angeordnet,
das bei Nichtgebrauch in eine Halterung 6 des Zapfmastes 1 eingesetzt wird.The tap shown schematically in FIG. 1 shows a tap 1, in
to which a
Der durch das Zapfventil 5 auszugebende Kraftstoff, vorzugsweise ein
bleifreier flüssiger Kraftstoff für Verbrennungsmotoren, wird aus einem nicht
dargestellten Vorratsbehälter über einen Filter 7 von einer Pumpe 8
angesaugt, die von einem nicht dargestellten Elektromotor angetrieben wird.
Dieser Elektromotor und damit die Pumpe 8 werden eingeschaltet, sobald das
Zapfventil 5 aus seiner Halterung 6 herausgenommen wird. Zu diesem Zweck
ist die Halterung 6 mit einem Schalter versehen, der unmittelbar den
Pumpenmotor einschaltet, sobald das Zapfventil 5 aus der Halterung 6
entnommen wird.The fuel to be dispensed through the nozzle 5, preferably a
unleaded liquid fuel for internal combustion engines, is not one
reservoir shown via a
Der von der Pumpe 8 geförderte Kraftstoff wird über einen Gasabscheider 9
und ein Rückschlagventil 10 einem Meßwerk 11 zugeführt, das vorzugsweise
als Kolbenzähler ausgebildet ist, Dieses Meßwerk 11 ist mit einem
Impulsgeber 12 ausgestattet, der entsprechend der Drehbewegung des
Meßwerkes 11 und damit der durchfließenden Kraftstoffmenge Einzelimpulse
abgibt, die in einer auf der Zeichnung nicht dargestellten Auswerteeinrichtung
zur Ermittlung sowohl der abgegebenen Menge als auch des sich hieraus
ergebenden Preises herangezogen werden. Menge und Preis der jeweils
ausgegebenen Kraftstoffmenge werden darüber hinaus auf einer nicht

Das Flüssigkeitssystem zwischen dem Rückschlagventil 10 und dem Zapfventil
5 ist normalerweise mit Kraftstoff gefüllt. Im Ruhezustand befindet sich
demzufolge Kraftstoff sowohl in der Rohrleitung 2 als auch im Zapfschlauch 3.
Da der Zapfschlauch 3 über Umlenkrollen 4 aufgerollt ist, ergibt sich beim
Einhängen des Zapfschlauches eine Volumenänderung, die von dem Meßwerk
wahrgenommen wird, so daß der Impulsgeber 12 einen Impuls abgibt. Die
Menge und der Preis werden daraufhin verändert und in der Anzeige
dargestellt. Selbst wenn diese Veränderung nur im Pfennigbereich liegt, ist
diese ungenau und für die Bedienperson störend.The fluid system between the
In Fig. 2 ist ein Impulsdiagramm dargestellt, welches im oberen Teil das
Einschalten der Pumpe 8 zum Zeitpunkt a zeigt. Nach dem Einschalten der
Pumpe und dem Öffnen des Ventils werden entsprechende Kraftstoffmengen
ausgegeben und die mit J1 bis J9 gezeigten Impulse über die Zeit festgestellt.
Die Numerierung erfolgt nur der Erläuterung, es werden insgesamt eine
beliebige Anzahl von Impulsen festgestellt, die zur Berechnung von Menge und
Preis und deren Anzeige verwendet werden. Zu irgendeinem Zeitpunkt, im
Anschluß an Impuls J9, wird das Ventil geschlossen. Es wird dann innerhalb
einer vorgegebenen Zeitspanne tX kein neuer Start des Meßvorganges
festgestellt. Dies wäre beispielsweise der Fall, wenn eine Bedienperson nach
Befüllung eines Haupttanks noch einen Kanister zusätzlich füllt oder eine
durch sonstige äußere Einflüsse beendete Kraftstoffeinfüllung wieder
aufnimmt. Außerhalb der Zeitspanne tX wird ein weiterer Impuls J10 erfaßt.
Auf diesen folgen aber keine weiteren Impulse, sondern der Meßvorgang wird
durch Abschalten der Pumpe im Punkt b, beispielsweise durch Einhängen der
Zapfpistole, beendet. Der Nachlaufimpuls J10 wird erfindungsgemäß nicht für
die Ermittlung von Menge und Preis verwendet sondern gelöscht.2 shows a pulse diagram which shows the switching on of the
Wird davon ausgegangen, daß als vorgegebene Anzahl von Impulsen ein Impuls festgelegt wurde, so würde der Impuls J10 dann bei der Ermittlung von Menge und Preis berücksichtigt werden, wenn nach seiner Erfassung weitere Impulse festgestellt würden, beispielsweise weil ein weiteres Reservoir befüllt wird, ein Kanister oder dergleichen, oder ein Betankungsvorgang weitergeführt wird. If it is assumed that a pulse has been defined as the predetermined number of pulses, the pulse J 10 would then be taken into account in the determination of the quantity and price if further pulses were determined after its detection, for example because another reservoir is being filled Canister or the like, or a refueling process is continued.
Diese Beschreibung ist nur ein Ausführungsbeispiel. Die Meßwerte müssen keine Impulse sein, sondern können jede Art von digitalen oder analogen Meßwerten sein. This description is only one embodiment. The measured values must not be impulses, but can be any type of digital or analog Be measured values.
