Description
Es ist in Fachkreisen der Hersteller von Benzinzapfsäulen, den Mineralölgesellschaften sowie dem Umweltbundesamt hinreichend bekannt, daß bei den Gasrückfuhrungsanlagen an Benzinzapfsäulen zu Ausfällen kommt.It is well known among experts at petrol pump manufacturers, oil companies and the Federal Environment Agency that the gas recovery systems at petrol pumps can fail.
Dem Tankstellenpersonal sowie dem tankenden Kunden ist dieser Ausfall der Gasrückführung nicht erkennbar. Eine Funktionsüberprüfung der Gasrückführunganlage an der Benzinzapfsäule mit dem jetzigem Stand der Technik ist nur mit großem Aufwand durch zu fuhren.The gas station staff and the customer filling up cannot detect this failure of the gas recovery system. A functional test of the gas recovery system at the gas pump is very difficult to carry out with the current state of the art technology.
LÖSUNG:SOLUTION:
Aufgrund der o. g. Problemstellung ist von mir eine Überwachungsvorrichtung der Gasrückruhrungsanlage an Benzinzapfsäulen entwickelt und als Prototyp gebaut worden. Diese Überwachungsvorrichtung ermöglicht, daß die sofortige Erkennbarkeit einer Funktionsstörung der Gasrückruhrungsanlage an jeweilig benutzten Benzinzapfsäule angezeigt wird und je nach Einstellung der Elektronik kann eine Abschaltung des Zaprpunktes erfolgen.Due to the above-mentioned problem, I developed a monitoring device for the gas recirculation system on petrol pumps and built a prototype of it. This monitoring device makes it possible to immediately detect a malfunction of the gas recirculation system on the petrol pump in use and, depending on the setting of the electronics, the pump point can be switched off.
Weitere Informationen sind der Funktionsbeschreibung der Überwachungsvorrichtung zu entnehmen.For further information, please refer to the functional description of the monitoring device.
1. Aufgabe der Ein- und Ausgänge: 1. Task of the inputs and outputs:
Eingang 1 : Überwacht die Steuerelektronik der GasräckfuhrungInput 1 : Monitors the control electronics of the gas return
Eingang 2 : Überwacht das Netzteil (Netzeingang DC 24 V)Input 2 : Monitors the power supply (power input DC 24 V)
Eingang 3 : Überwacht die Vakuumpumpe der GasrückführungInput 3 : Monitors the vacuum pump of the gas return
Eingang 4 : Überwacht das Magnetventil der GasrückführungInput 4 : Monitors the gas return solenoid valve
Eingang 5 : wird durch den ZapfVentilschalter gesteuertInput 5 : is controlled by the tap valve switch
Ausgang 1 : Steuert die Kontrollampe Ll (Grün)Output 1 : Controls the indicator lamp Ll (green)
Ausgang 2 : Steuert die Kontrollampe L2 (Rot)Output 2 : Controls the indicator lamp L2 (red)
Ausgang 3 : Steuert die Kontrollampe L3 (Rot)Output 3 : Controls the indicator lamp L3 (red)
Ausgang 4 : Steuert die Kontrollampe L4 (Rot)Output 4 : Controls the indicator lamp L4 (red)
Ausgang 5 : Steuert den Schalter S1 (Öffner)Output 5 : Controls switch S1 (normally closed)
2. Funktionsbeschreibung der Uberwachungselektronik; 2. Functional description of the monitoring electronics;
Die Überwachungselektronik hat die Aufgabe, alle Teile der Gasrückführungsanlage über die Eingänge 1 bis 4 zu überwachen, die Fehler durch die Kontrollampen anzuzeigen und notfalls <äe Zapfsäule durch den Öffner Sl abzuschalten.The monitoring electronics have the task of monitoring all parts of the vapour recovery system via inputs 1 to 4, indicating errors via the control lamps and, if necessary , switching off the fuel pump via the opener Sl.
Durch den Explosionsgeschutzten Unterdruck- Wächter wird der Durchfluß des Gases vor der Pumpen kontrolliert.The explosion-proof vacuum monitor controls the flow of gas upstream of the pump.
Das Magnetventil, das Netzteil und das Steuerelektronik- Module werden kontrolliert, in dem sie direkt an die Überwachungselektronik angeschlossen sind.The solenoid valve, the power supply and the control electronics modules are controlled by being connected directly to the monitoring electronics.
Siehe Blockschaltung.See block circuit.
Die Kontrollampen sind an einem sichtbaren Feld z.B. Anzeigebereich der Zapfsäule montiert, um die Überwachung der Anlage durch Personal und Kunden ohne großen Aufwand zu ermöglichen.The control lamps are mounted in a visible area, e.g. the display area of the fuel pump, to enable the system to be monitored by staff and customers without great effort.
3. Funktiopsbeschreibung der Kontroilampen: 3. Functional description of the control lamps:
1-Ll EIN: Die Anlage ist Bereit. 1-Ll ON: The system is ready.
Solange kein Fehler auftritt bleibt Ll (Grün) an.As long as no error occurs, Ll (green) remains on.
Ll AUS: Die Anlage ist nicht bereit, eine oder mehrere der Kontrollampen L2 bis L4 (Rot) ist an. Ll OFF: The system is not ready, one or more of the indicator lamps L2 to L4 (red) is on.
Sl öffnet nach der laufenden Tankung. Die Zapfsäule (ZS) schaltet ab und geht in den Stoppzustand.Sl opens after the ongoing refueling. The fuel pump (ZS) switches off and goes into the stop state.
2-L2 EIN: Die Steuerelektronik ist außer Betrieb.2-L2 ON: The control electronics are out of order.
Ll ist aus, Sl öffnet nach der laufenden Tankung. Die ZS schaltet ab und geht in den Stoppzustand.Ll is off, Sl opens after refueling is complete. The ZS switches off and goes into the stop state.
L2 AUS: Die Steuerelektronik ist betriebsbereit.L2 OFF: The control electronics are ready for operation.
3-L3 EIN: Die Vakuumpumpe ist außer Betrieb.3-L3 ON: The vacuum pump is out of operation.
Ll ist aus, Sl öffnet nach der laufenden Tankung. Die ZS. Schaltet ab und geht in den Stoppzustand.Ll is off, Sl opens after refueling is complete. The ZS switches off and goes into the stop state.
L3 AUS: Die Vakuumpumpe ist betriebsbereit.L3 OFF: The vacuum pump is ready for operation.
4-L4 EEV: Das Magnetventil ist außer Betrieb. 4-L4 EEV: The solenoid valve is out of order.
Ll ist aus, Sl öffnet nach der laufenden Tankung. Die ZS Schaltet ab und geht in den Stoppzustand.Ll is off, Sl opens after refueling is complete. The ZS switches off and goes into the stop state.
L4 AUS: Das Magnetventil ist betriebsbereit. L4 OFF: The solenoid valve is ready for operation.
5- Alle Kontrollampen sind AUS: Das Netzteil ist außer Betrieb.5- All indicator lights are OFF: The power supply is out of order.
