Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a refueling device in which display items regarding refueling from a plurality of refueling nozzles are divided and displayed on the - display surface of a display.

In conventional refueling devices, one indicator is installed for each refueling device, and each indicator displays the amount of fuel supplied by each refueling device.

For this reason, when a large number of oil supply devices are installed, the number of indicators increases accordingly, which not only increases equipment costs but also makes wiring work difficult.

Furthermore, since a plurality of display devices each require a display element, maintenance is required for each display device, which poses problems in terms of maintenance costs and maintenance.

In order to solve the conventional problems, this invention is a refueling system that has multiple refueling systems in which a refueling hose equipped with a refueling nozzle is connected to a pipe connected to a tank and a flow meter interposed. A cathode tube type display is provided at a location easily visible to workers and customers, and the display items for each of the above-mentioned lubrication systems are displayed at once, and the cathode tube type display is attached to the flow meter of each of the above-mentioned lubrication systems. The pulse transmitter is connected via a drive circuit that displays display items related to one or more of the refueling systems in use on the display screen of the cathode tube display, and is further connected to the drive circuit. The present invention provides a refueling device equipped with a video circuit that switches only display items related to the refueling system in use to an enlarged display mode by operating a changeover switch.

With this configuration, display items regarding each fuel supply system can be displayed in sections on the negative display, and the display items can be enlarged and displayed as necessary.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows the present invention applied to a ceiling-suspended oil supply device.

1 is a pump driven by a motor (not shown), the inflow side of the pump 1 is connected to an underground pipe 3 communicating with an underground tank 2, and the outflow side of the pump 1 is connected to the inflow side of a flow meter 4. There is.

A pipe 5 is connected to the outflow side of the flow meter 4, and the pipe extends to a high place 6 at a refueling station.

8 is a refueling nozzle attached to the tip of the refueling hose 7.

Here, a plurality of oil supply systems are constituted by the pump 1, flow meter 4 piping 5, oil supply hose 7, oil supply nozzle 8, and the like.

A negative cathode tube type display 9 is provided at a position easily visible to refueling workers and customers, and the display 9 is connected to a drive circuit 10.

Reference numeral 11 denotes a pulse transmitter that converts the rotational speed of the flow meter 4 according to the amount of oil supplied into an electrical pulse signal.

FIG. 2 shows the detailed configuration of the drive circuit 10.

The pulse transmitter 11 of each refueling device is connected to the input side of a multi-counter 12 that sequentially converts pulse signals into count signals, and the video switching circuit 13 is connected to the output side of the multi-counter 12.

The video switching circuit 13 is operated each time the video is switched by a changeover switch 14 installed in an office or the like.

The video switching circuit 13 includes a frequency converter 15 and a video converter 1.
6 are connected, and a signal is output from the video converter 16 to the display 9.

A periodic signal separator 17 is connected to the video converter 16, and a vertical synchronization circuit 18 and a horizontal synchronization circuit 19 are connected to the synchronization signal separator 17.

In this case, oil is supplied from the oil supply nozzle 8.

When a pulse signal is output from a pulse transmitter 11 provided in each flow meter 4 in accordance with the amount of oil supplied, the pulse signal is input to a multi-counter 12, where it is converted into a count signal and output.

This count signal is converted into an image by the video converter 16 via the frequency converter 15, the periodic signal separator 17, the vertical synchronizing circuit 18, and the horizontal synchronizing circuit 19, and is displayed on the - display surface 9a of the cathode type display 9. Refueling amount 2 supplied from each refueling nozzle 8
0 is divided and digitally displayed for each refueling system (3rd
(see figure).

In this case, the refueling, device number 21, liquid type 22, unit price 23, and amount 24 may be displayed on the display surface 9a (see FIGS. 3 to 5), and the pulse transmitter 11
If no pulse signal is input from the
As shown in the figure, nothing is displayed on the portion 26 corresponding to the unused oil supply system.

If refueling is performed only from the refueling system, operate the image switching circuit 13 using the changeover switch 14, and as shown in FIG.
The liquid type 22, oil supply amount 20, unit price 23, and amount 24 are enlarged and displayed.

Furthermore, when all of the refueling systems are in an unused state, the changeover switch 14 transmits the image from the applicable television set to the display 9 for advertising or the like.

In this embodiment, the refueling nozzle 8 is applied to a ceiling-suspended refueling device in which the refueling nozzle 8 is vertically suspended from a height 6, but the present invention is not limited to this, and the refueling nozzle 8 can be attached to and detached from a main body installed on an island. It may also be applied to ground-mounted refueling equipment hung on the ground.

As described above, in the present invention, display items related to refueling from a plurality of refueling systems are displayed in a concentrated manner on a single display, which not only reduces the cost but also facilitates wiring work, etc.

Furthermore, even if the number of oil supply systems increases, only one display is required, making maintenance easier.

Furthermore, the display surface of the display unit displays display items related to the refueling system in appropriate sections, making it easy for both customers and workers to see, and desired display items can be enlarged and displayed as necessary. Since it is possible to accurately indicate the refueling details to the customer, it is possible to gain the customer's trust and provide prompt service.
