Abstract

PURPOSE:To inform an oil feeding operator of an inappropriate oil feeding car for full charge, by an alarm when identifying data on customers or oil feeding cars read by an identifying data reading means coincide with data on an oiling car which is prohibited from fully charging stored in a storage means for prohibiting feeding the tank with oil to the full. CONSTITUTION:Identifying data of customer codes, etc. of oil feeding card unsuitable for automatically full charge are stored in the memory of a POS terminal controller 12 as the identification data of prohibited full charge of oil. The POS terminal controller 12 compares the data read from a card reader 13 with the data stored in the memory on prohibited full charge of oil and when both data are not equal, the oil feeding data are fed to a measurer controller 8 via an interface 19, a data bus D and an interface of a measurer 1. An alarming lamp 7 lights or flickers when disagreed data are input from the POS terminal controller 12 via the measurer controller 8 to indicate an unsuitable oil feeding car.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a refueling system, and particularly to a refueling system suitable for use in a refueling station equipped with a weighing machine having an automatic refueling function.

[Prior Art] Conventionally, there is a metering machine that has a refueling nozzle equipped with an automatic valve-closing mechanism that closes the valve based on the negative and positive values that occur as refueling progresses. There is a problem in that the bubbles generated from the liquid level of the fuel tank cause the valve of the refueling nozzle to close before accurate refueling is completed, ending full refueling.

Therefore, in order to solve this problem, a liquid sensor that detects the liquid level of oil in the vehicle fuel tank or a liquid foam sensor that detects bubbles generated from the liquid level is installed at the tip of the refueling nozzle. When the liquid level of the vehicle fuel tank in which the nozzle is set rises as the refueling process progresses, based on the detection signal from the sensor, a pump or electromagnetic device installed on the upstream side of the refueling nozzle, that is, inside the metering machine, is activated. A weighing machine has been developed that is configured to automatically fill up the tank by driving and controlling a valve.

In this metering machine, the pump motor is stopped when the sensor turns on after a predetermined time after starting refueling, and it is determined whether the sensor is turned on after a predetermined foam disappearance waiting time.

When it turns OFF, it is assumed that the bubbles have disappeared, and the pump motor is driven for a predetermined period of time, and after a predetermined waiting time for bubbles to disappear, it is again determined whether the sensor 7 is ON or not. When it turns OFF, the bubbles have disappeared. In addition, the pump motor is driven for a predetermined period of time, and after a predetermined foam disappearance waiting time, it is determined whether the sensor is ON or not, and if it is ON, it is determined that full refueling has finally been performed. It has become.

[Problems to be Solved by the Invention] By the way, in the above-mentioned conventional weighing machine equipped with an automatic refueling function, although accurate refueling can be performed,
There were still problems as follows.

■Depending on the vehicle model, the arrangement shape of the fuel tank, the fuel filler port of the fuel tank, or the fuel filler pipe leading from the fuel filler port to the fuel tank varies.In particular, if the fuel filler pipe is bent, the above-mentioned metering machine will automatically fill the fuel tank. If tank refueling is performed, problems such as oil leaking from the refueling port may occur.

■When a refueling vehicle of a non-conforming model with a bent fuel pipe, etc. as described above approaches a refueling station, the refueling man does not check whether the refueling vehicle is of a non-conforming model or not. However, there is a risk that the automatic refueling operation will continue, causing oil to spray out from the refueling port, or determining that the fuel tank is full even though it is not, and ending refueling. Problems such as time consuming refueling may occur.

The present invention solves the above-mentioned problem, and by preventing leakage of oil from the fuel filler port of a vehicle and incomplete refueling during automatic refueling, it improves safety, improves the efficiency of refueling work, and improves customer satisfaction. The aim is to provide a refueling system that improves service.
