Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a refueling station having a plurality of refueling areas for one refueling device.

If the engine of the vehicle being refueled is running during refueling, there is a risk of ignition, so the engine must be stopped. Conventionally, this involved turning off the engine key, pulling out the engine key, inserting the engine key into a lid provided at the opening of the fuel tank, and opening the lid. However, depending on the car model, the fuel tank lid can be opened by operating the driver's cab, and some lids do not have locks, and there is also a risk that the driver may forget to stop the engine due to a mistake. .

To this end, the present applicant has proposed a gas station in which an engine stop detector is installed in the refueling area, and refueling is possible in response to a stop signal from the engine stop detector.
No. 66955) Q This engine stop detector detects electromagnetic waves from the engine's spark plug.

Now, normally at a gas station, a fueling device is provided with a plurality of refueling areas, and vehicles entering any of the refueling areas can be refueled.

For this reason, when there are multiple refueling areas, an engine stop detector must be provided in each of the refueling areas. Then, even if a vehicle that has entered one refueling area stops its engine, if another vehicle enters the other refueling area, the rotation of the second engine of that other vehicle is detected as the engine stop in the other refueling area. Vehicles refueling in one refueling area will stop refueling.

Therefore, an object of the present invention is to detect engine stoppage of a vehicle in a refueling area where refueling is to be performed at a refueling station that has a plurality of refueling units for one refueling device, and to detect engine stoppage in other refueling areas. We provide a fueling station where you can refuel your vehicle regardless of whether its engine is running or stopping.

According to the present invention, the engine stop detector provided in each refueling area, the refueling request detector and the refueling area discriminator provided in the refueling device are provided, and the stop detection signal from the engine stop detector and the refueling request are provided. Refueling request detection signal from the detector and refueling from the refueling area discriminator] A control I device is provided which determines the refueling capability state of the refueling area determined based on the input of the refueling request detection signal and the refueling area discriminator.

Therefore, when a vehicle enters a gas station and stops at the refueling area and starts refueling, the refueling area discriminator determines which refueling area should be refueled, and the engine stop detector detects the vehicle. of a vehicle stopped in the determined refueling area]-
Only when the engine is stopped, the refueling device is driven by a signal from the refueling request detector and can begin refueling.

Therefore, by implementing the present invention, refueling work cannot be performed unless the engine of the vehicle to be refueled is stopped, and it is completely free from the influence of other vehicles entering the refueling area. Therefore, it is extremely suitable.

In implementing the present invention, it is preferable to use a switch that detects the direction in which the refueling hose is pulled as the refueling area discriminator. When such a discriminator is used, it can be seen that the vehicle to be refueled is leaning toward the refueling-L rear in the direction of the switch that is pulled and turned on.

Further, as the engine stop l-detector, it is preferable to use an antenna or a coil that detects electromagnetic waves generated from a spark plug of the engine. By using such a detector, it is possible to detect the rotational state of an automobile engine and display whether the engine is normal or abnormal. J
The vehicle entering the normal refueling area is idling for several seconds, and the 40'J engine stops. Therefore, this idling state can be detected.

Hereinafter, an example of a stationary fueling station in which the present invention is implemented in a fixed fueling system will be described with reference to the drawings.

In Figs. 1 and 2, a fixed stand S is installed at an island L sandwiched between rear A and B of a gas station. A pump 2 driven by a motor 1 is installed in the stand S. The pump 2 sucks oil from a tank (not shown), sends it to the hose 1 via the flow rate ff+3, and then flows out from the oil supply nozzle 5. FUt] flow rate pulse transmitter 6
sends the pulse signal to the refueling display 7, and displays refueling on the display. On the island L near the stand S, there is a built-in control device 15, and a table 5 on the refueling area A side for displaying the idling state of the engine.
= A display device 25 is provided in which the temperature indicators 8a and 8b and the display device 8b on the fueling area 13 side are placed back to back.

The indicators 8a and 8b are equipped with a rotational speed display it 10 for displaying the engine rotational speed and a display lamp 11 for indicating whether the engine is idling. On the floor of the rear refueling balls A and B, there are vehicle detectors 12a and 12b consisting of coils that detect iron, etc., and engine stop detector 13a consisting of an antenna or coil that detects electromagnetic waves generated from the engine's spark plug.
and 13 b h< provided.

On the other hand, the stand S is provided with a refueling area discriminator 26 that determines whether refueling area Δ or B is to be refueled.

FIG. 3 shows a preferred embodiment of the refueling area discriminator 26 implemented in the present invention.

Refueling hose 4 is attached to swivel joint 2 at stand S.
This swivel joint 1-27 has an elbow 27a. This elbow 27a is provided with a cam 28 6-611'C. During refueling work, when refueling ψ cars parked at Refueling 1 Rear A, the bow 4 is pulled in the IJ direction to the arrow in Figure 3, so the elbow 27aLl
, the microphone switch 20a is turned on by the cam 28. Also, when refueling Φ cars parked at Refueling Eritsuno B, go in the opposite direction -[
Rubo 29E1 rotates +>J, so micro switch 29
1) is on.4I:.

However, if the microphone [1 switch 29a is turned on, refueling] Rear Δ-C is detected to be refueling, and the microphone [1 switch 29a is turned on, the refueling area B is refueled. It is detected that the vehicle is being refueled. Therefore, Ni il+ T-rito's l'll separation can be (-1).

In FIG. 1, a nozzle switch SW for determining whether the refueling nozzle 5 is attached to the nozzle J of the stand S or old is provided on the nozzle 1 well. This nozzle switch S
W constitutes a refueling request detector.

Various equipment such as the pump motor 1 mounted on the stand S and the various detectors 12a, 12b, 13a and 13 installed on the floor of the supply area A
b is connected to the control device 15 installed in the display device 25 via a line not shown. In addition, the control device 15 can also utilize the functions of a conventionally used refueling data and turnout device.

At j3 in FIG. 4, the control device 15 is provided with a central processing section 16, which controls the pump motor 1 via an input/output device @17.
etc. are connected to each device. Therefore, signals from each device are input to the central processing unit 16 via the input/output device 17, and signals from the central processing unit 16 are input to the input/output device 1.
The control device 15 also has a ROM (R
OM) 20 and a RAM having a temporary storage section 22
23 and a timer 24.

The present invention will now be described in detail with reference primarily to the flowchart of FIG.

When a car (not shown) enters, for example, the fueling area A of a gas station, the engine of the car is rotating, and the engine stop detector 13 a I;1 generates electromagnetic waves due to the rotation of the engine. Detected.

A pulse signal of electromagnetic waves from the detector 13, 1 is sent to the central processing unit 11 via the input/output device 17.
1! The central processing unit 16 (timer 2/l IJ day) is manually operated by the central processing unit 16. 9, determines whether the condition of the engine is good or not, stores the binding in the memory section 22, and when a pulse signal is input, stores a signal indicating that the engine is running in the temporary memory section 22. Then, if the pulse signal is not input for a time of, for example, 200 m5ec or more, one engine will not be able to drive the engine as described in Case 11:, 1., and b.
The + medium signal was turned off. When the operator removes the refueling nozzle 5 from the nozzles $1) f and l and pulls it toward the refueling area A, the nozzle switch turns on, and when the slave signal is transmitted to the central processing section 16, the central processing section 16 is determined to be a refueling request (step S1). Next, when the hose is pulled toward the refueling area A, the microswitch 29-9a is turned on, and upon receiving this signal, the central processing unit 16 determines that refueling is to be performed in the refueling area A (
Step 82).

Next, the central control unit 16 determines whether the engine driving signal is stored in the temporary storage unit 22 or not, and if it is not stored, it is determined that the engine is stopped (step S3).
Based on these judgments, it is finally determined that refueling is possible, the previous refueling amount shown in display ^17 is returned to zero, and the pump drive motor 1 is
(step S4).

Then, normal refueling work is performed. During this refueling operation,
The flow rate pulse signal from the pulse transmitter 6 of the flow cutting 3 is transmitted to the display meter 7, and the oil supply amount is displayed on the oil supply amount display meter 7. During refueling work, it is always determined whether the engine is stopped or not. That is, during refueling work, the nozzle switch SW is always on, so the answer in step S5 is always YES, and then the pulse signal from the engine stop detector 13a is input, and that signal is stored in the temporary storage section 22. (Step 10-Tub 86).If the J-engine is malfunctioned due to an erroneous operation, the GEL sub-tube S6 determines that the engine is being driven and turns the pump motor 1 to (Sj"□7JS7). Also, when the refueling operation is completed and the nozzle lever is operated - (close the valve of refueling nozzle 5 and hang the refueling nozzle h on the nozzle hook, the nozzle switch SWl,
LA), it is determined that the refueling is finished, step S5), and the pump motor 1 is stopped (step S7).

When the driver leaves the vehicle, the detection signal from the vehicle detector 12a disappears, it is determined that the vehicle has left the vehicle, and the display on the display device 8a disappears. Note that when refueling is performed in the refueling area [3 side, when the hose 4 is pulled toward the B side, the microphone ITI switch 29b is turned on, and if step 82 is No, it is determined that refueling is to be performed in refueling area B in step S8. (Explained in refueling at A), step S in the same way as:
9. Proceed to Sumitsubu S7 using the shuttle S IQ N S II 1SI2. In this way, refueling work (1 nozzle switch SW and micro switch 29a or 1 or 29b)
is turned on and there is no pulse signal from the engine stop L detector 13a or 1311, so refueling is not performed during engine startup, and the risk of ignition can be completely prevented.

FIG. 6 shows an example in which the present invention is applied to a hanging fuel station. Therefore, parts corresponding to those in FIG. 1 are designated by the same reference numerals. At 43 in FIG. 6, for example, a display 817 indicating the amount of refueling is provided on the outer wall of the office O, and a display 8 is also provided for displaying the number of rotations of the engine and the quality of the idling state of the engine. On the other hand, a hanging type refueling machine 3a is fixed to the canopy K, and a hose 4 having a refueling nozzle 5 at its tip is suspended from the refueling machine Sa. In this embodiment as well, the area below the refueling tfisa is divided into refueling areas A and B, and each refueling area A and B has vehicle detectors 12a and 12b, respectively.
and an engine stop detector 13a113b. The refueling machine Sa includes a switch 29a that determines whether refueling area A or B is to be refueled;
29b is provided. The operation and effect of this embodiment are substantially the same as those of the previous embodiment.

According to the present invention, the above-described 1J6) is provided with a 1-engine stop detector installed in the refueling area, a refueling request detector and a refueling area discriminator installed in the refueling device, and the A stop detection signal from the engine stop detector; a refueling request detection signal from the refueling request detector; and a refueling area determination signal from the refueling J7 discriminator. Since the refueling area is equipped with a control t41ff, it is possible to start the refueling operation in response to a signal from the refueling request detector only when the engine of the vehicle on the refueling area side is stopped.
By efficiently refueling vehicles in multiple refueling areas without being affected by vehicles entering other refueling areas, it is possible to reduce the risk of fire caused by the rotation of the engine of the vehicle being refueled. .
