Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fueling device for a fueling station for fueling a vehicle such as gasoline.

[0002]

2. Description of the Related Art As is well known, such a refueling device of the type fixed above the ground is provided with a housing installed on the ground, a fuel supply pipe communicating with an underground oil storage tank is set up, and the fuel supply motor is connected to the fuel supply pipe. An oil supply mechanism such as an oil supply pump and a flow meter is provided, the tip of the oil supply pipe is connected to the oil supply hose outside the housing, and an oil supply nozzle is provided at the end of the oil supply hose. A display that displays oil supply data such as the amount of oil supply. The container is provided on the front surface or both front and rear surfaces of the housing.

In this display, a dot type display as shown in, for example, Japanese Patent Laid-Open No. 61-217396, and
There are 7-segment type as shown in JP-A-58-171397 and JP-A-59-3696. Among these, the dot type has a display portion formed in a horizontally elongated rectangular shape. A large number of dots are arranged in rows and columns, and a dot to be energized is appropriately selected to display a number indicating the amount of oil supply or a character indicating the oil type.

In the 7-segment type, seven display elements are combined in a Japanese letter shape, and these seven display elements are appropriately arranged.
Numbers or alphabetic characters are displayed in this combination with the display state or non-display state. Normally, the refueling amount does not exceed 1000th place digit, so 100th place up to 2 digits below the decimal point are displayed. For this purpose, five numbers that are combined in the shape of a letter are arranged in a row, and a number indicating the amount of refueling is displayed.

[0005]

By the way, the size of the indicator of such a refueling device is limited because it needs to have a pressure-proof and explosion-proof structure. On the other hand, it is desired that the display simultaneously displays the oil type and other information in addition to the oil supply data such as the oil supply amount.
In the case of the dot type shown in Publication No. 6, in order to display other indications at the same time as the refueling amount, the display part of the refueling amount should be reduced or replaced with the part formed as the unit price or amount display part. Since other information is displayed, the number indicating the amount of refueling becomes small and difficult to see, and the unit price and the amount of money are not displayed. Instead, this information cannot be obtained.

On the other hand, JP-A-58-171397 and JP-A-59
In the case of the 7-segment type shown in Japanese Patent No. 3696, in order to display other information at the same time as the refueling amount, there is usually almost no refueling of 99l or more. The portion of the 100th digit that is never used is used as a display portion for other information.
-171397, "P" for preset lubrication and "F" for free lubrication are displayed in the 100th digit.
In No. 3696 bulletin, a symbol such as "small" for cash customers, "ko" for credit customers, "E" when there is information for cash customers, and "yo" when there is information for cash customers. Is displayed at the 100th digit.

However, in this method, when the amount of refueling reaches 99.99 liters or more, information other than the amount of refueling cannot be displayed, and the amount of refueling is 99.99 liters or less.
Even if the 100th digit can be used as another information display part, it may be mistaken as a number because it is displayed in symbols or alphabets, which may lead to misidentification of the amount of refueling.

An object of the present invention is to eliminate the disadvantages of the conventional example and to display other information at the same time as the amount of refueling on the display, so that the number indicating the amount of refueling is not reduced and becomes difficult to see. It is an object of the present invention to provide a refueling device capable of simultaneously displaying other information even when the refueling amount is 99.99 liters or more without misidentifying the information display of as a number indicating the refueling amount.

[0009]

In order to achieve the above object, the present invention provides that the color of the refueling data display portion and the color around the display portion are preset depending on the type of oil and the refueling state such as refueling or non-refueling. The gist is to provide a color display device that automatically changes to the set color.

[0010]

According to the present invention, for example, the color of the number indicating the amount of refueling and the color around the number displayed on the refueling data display unit are preset depending on the type of oil and whether it is refueled or not. Since it is represented by a color, the color itself displays information, and by identifying these colors, information other than the amount of refueling such as the type of oil currently being refueled and whether or not refueling is in progress is obtained. be able to.

A nozzle switch 10 is provided on a nozzle hook 9 formed on the side surface of the housing 1 or the like so as to be turned on and off in association with the hooking and unplugging of the oil supply nozzle 7, and the unit price and oil type of the oil to be supplied are input at appropriate places. An input switch 11 is provided for In the figure, reference numeral 12 is a display for displaying refueling data such as refueling amount and information such as oil type. In the present invention, the display 12 is composed of a color display such as a color liquid crystal color LED or a color CRT.

Further, a control device 13 using a conventionally known microcomputer or the like is provided. FIG. 2 shows this controller 13
In the block diagram of the display control and refueling control by the, the oil type setting signal from the input switch 11 is introduced into the oil type storage means 14 for storing the oil type such as regular, high octane, and light oil, and the oil type signal from this is color-coded. Introduced in the storage means 15. In this color arrangement storage means 15, the color of the refueling data display portion such as the refueling amount displayed on the display 12 and the color of the back thereof are different depending on the oil type.
Further, different colors and colors are preset and stored depending on whether the fuel is being supplied or not.

As an example of the color arrangement, during non-refueling, the number of refueling amount shown in the refueling data display section for regular, high-octane oil, and light oil is the die-dye color, the background color is blue for regular, and high-octane is sky blue. , Light oil is yellow. And, during refueling, the number of refueling amount displayed on the refueling data display area is blue for regular, high-octane, and light oil,
The color of the back is regular, it is yellow, high-octane is yellow, and light oil is sky blue.

Further, the unit price setting signal from the input switch 11 is introduced into the unit price storing means 16, and the unit price signal from the unit price storing means 16 is introduced into the calculating means 17 for calculating the refueling amount.

Using the ON signal of the nozzle switch 10 as a reset signal, it is introduced into the counting means 18 into which the pulse signal from the flow rate pulse transmitter 5 is introduced, and the counting signal from the counting means 18 is introduced into the computing means 17. The refueling data signal from here is introduced to the drive means 19 of the display 12. Further, the ON signal of the nozzle switch 10 is introduced as a drive signal into the drive means 20 of the refueling motor 3 and at the same time introduced into the color arrangement storage means 15 as a color change instruction signal, and the color arrangement signal from this is introduced into the drive means 19 of the display 12. To do.

The OFF signal of the nozzle switch 10 is used as the drive means 20 for the refueling motor 3 and the color arrangement storage means 15 is used as a color change instruction signal.
