In addition, this refueling permission alarm] 1 and refueling end alarm 12
This may be configured with a buzzer, and the installation location is not limited to the above example.

Reference numeral 13 in the figure is a preset amount indicator that displays the scheduled refueling daytime 4C that has been set in advance.

Each of the refueling machines 1a to 1d having such a configuration is controlled by a control device 15 using a computer terminal installed in an office 14 within the refueling station.

By the way, although the embodiment illustrated above is an example of a fixed refueling machine installed on the ground, it is also possible to use the device of the present invention in a hanging hose type refueling equipment where the refueling hose is suspended from a canopy. In this case, the refueling permission indicator 11 and the refueling end indicator 12 may be installed in a hose storage case or the like.

FIG. 2 is an external view of the operation panel of the control device 15.
(L~16d are refueling machine selection push button switches for selecting the refueling machine to be used from among refueling machines 1α~1d, 17 is a pre-cent press button switch for setting the preset refueling amount, 18α~18
d is a preset amount display meter that displays this precent amount;
19 is a slip issuing machine.

Next, the relationship between the control device 15 and the refueling machines 1α to 1d is determined in a third manner.
The block diagram in the figure will be explained. In addition, in this Fig. 3, the details of the refueling machines 1b to 1d, and m+c are the refueling machines 1a.
Since it is the same as , the description is omitted.

Instead, the preset amount signals A of the preset device 20 consisting of the refueling machine selection push button switches 16α to 16d and the preset push button 17 are respectively introduced into the memory circuit 21 for each refueling machine, and these signals A are inputted from the memory circuit 21. In response, a preset amount signal C is sent to the arithmetic circuit 22, a slip issuing signal is sent to the slip issuing machine 19, and a preset amount is displayed on the preset amount display meter 18α of the control device 15 and the preset amount display meter 13 of the refueling machine 1a. The signal E and the lamp lighting signal F are introduced to the refueling permission alarm 11, respectively.

On the other hand, when the nozzle pulp 7 is removed from the nozzle hook,
The pump start signal G is sent from the nozzle switch 10 to the pump motor 3 via the AND circuit 23, and the return signal H is sent to the pump motor 3 via the AND circuit 23.
to the refueling amount indicator 9, and the Kiyosumi signalman to the refueling permission indicator] 1
Each will be introduced.

When the nozzle pulp 7 is applied to the nozzle, a clarification signal J is introduced from the nozzle switch 10 to a refueling end indicator 12 and a memory value cancellation signal B is introduced to the memory circuit 21.

Furthermore, the flow rate pulse signal K from the flow rate pulse transmitter 8 provided in the flow meter 4 is introduced into the arithmetic circuit 22, and 1 is subtracted from the precent amount from the memory circuit 21, and if the value is greater than zero, the arithmetic circuit 22, a pump start signal M is introduced into the AND circuit 23 and a valve open signal N is introduced into the valve 5. When the numerical value becomes zero, the above signals disappear and a lamp lighting signal O is introduced into the refueling end alarm 12.

Next, to explain the operation and usage, a customer who has stopped near the refueling machine 1α goes to the office 14 and tells the clerk that he would like to refuel, for example, 30 at the refueling machine 1α.

The clerk presses the 1α switch 16α among the refueling machine selection pushbutton switches 16a to 16tt, and then presses the 50t button of the preset push buttons 17. The pre-sent amount is stored in the storage circuit 21 of the refueling machine 1α, and Memory circuit 21
In response to a slip issuing signal from , the slip issuing machine 19 issues a refueling slip 24 on which the refueling machine number, amount of refueling, unit price, amount of refueling, etc. are printed as shown in FIG.

In addition, the memory value display signal E from the memory circuit 21 causes
The display meters 13 and 18a display the preset amount, the lighting signal F from the same circuit 21 causes the refueling permission alarm 11 to light up, and the stored value of the preset amount in the memory circuit 21 is preset. The amount signal C is introduced into the calculation circuit 22.

At this time, if the numerical value of the calculation circuit 22 is other than zero, the valve opening signal N is introduced to the valve 5 from the calculation circuit 22, and the valve 5 opens.
Also, the pump start signal M is sent from the arithmetic circuit 22 to the AND circuit 2.
Introduced in 3.

When the worker sees that the refueling permission indicator 11 of the refueling machine 1a is lit, he removes the nozzle pulp 7 of the refueling machine 1α from the nozzle, and the nozzle switch 1o sends the pump start signal G to the AND circuit 23. The AND circuit 23 receives the signal G together with the pump start signal M and starts the pump motor 3.
In response to this, the pump motor 3 starts.

At the same time, the refueling permission indicator 11 is cleared by the clearing signal from the nozzle switch 1o, and the previous refueling amount on the refueling amount indicator 9 is returned to zero by the return signal H from the same switch 10. .

What happens when you open nozzle valve 7 and refuel? ]C amount #l'
4 is activated, the refueling amount is displayed on the display meter 9, and the pulse pickling K from the pulse transmitter 8 provided in the flow meter 4 is transmitted to the arithmetic circuit 22.
When the preset amount signal from it decreases and its numerical value becomes zero, the valve opening signal N to the valve 5 and the pump start signal M to the pump motor 3 disappear, and the valve 5 closes and the pump motor 3 stops.

In addition, the lighting signal O from the arithmetic circuit 22 is sent to the refueling permission alarm 1.
At 2, this lights up.

When the worker sees that the refueling end indicator 12 of the refueling machine 1a lights up, he hooks the nozzle pulp 7 of the refueling machine 1a to the nozzle hook, and a pump start signal G is sent from the nozzle switch 10 to the pump motor 3. disappears, and the memory value erasing signal B is introduced from the same switch 10 to the memory circuit 21 to erase the memory of the memory circuit 21. In response to this, the memory circuit 21 erases the memory value display signal +3E and presets. Quantity display meter 1
3. The display of 18α also disappears.

Note that when any of the other refueling machines lb to 1d is used, the same operation as described for -J: refueling machine 1a is performed. J As described above, in the refueling system of the present invention, each of the plurality of refueling machines is provided with a refueling permission alarm and a refueling completion alarm, so that an operator can remotely monitor the operating status of each refueling machine using these displays. It is something that can be known at a glance.

Therefore, there is no need for a worker to be near the refueling machine at all times during refueling, as is the case in the past, and management can be done by a small number of people.

Furthermore, since the refueling permission alarm and the refueling end alarm are constructed of lamps or buzzers, even workers who are doing other work at a remote location can be sure of their display.
