〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing the overall structure of a refueling guide device according to an embodiment of the present invention, FIG. 2 is a front view showing the external structure of a vehicle guiding device according to the same embodiment, and FIG. 3 is a perspective view of the vehicle guiding device according to the embodiment. FIG. 2 is a block diagram showing an electrical configuration.

In these figures, a fueling station 1 has a plurality of fueling machines 2-i.
(+=1.2...K) is installed.

Further, a vehicle guidance system @5 is installed near the entrance 4 of the vehicle 3, and is connected to each refueling machine 2-i by a communication cable 6-1.

The vehicle guidance device 5 monitors the refueling state and refueling state of each refueling machine 2-i, and selects the refueling machine 2-1@ that has the minimum refueling capacity.
It is selected and displayed. That is, the selected refueling If! (2-2 in Figures 1 and 2) is the vehicle guidance system!
In addition to displaying on the vehicle guidance display 11 within ¥5,
The vehicle guidance lamp 7 provided on the upper part of ll12-i is turned on.

In addition to the vehicle guidance indicator 11, the vehicle guidance device 5 includes an inter-preset indicator 1 that displays the amount of refueling during preset refueling.
2, a preset amount display 13 that displays the refueling amount at the time of preset refueling, a unit price display 14 that displays the unit price per oil, and a driver of the vehicle 3, that is, a customer, to display the oil type and preset value. An oil type selection key 15 and a preset key 16 for setting a value (preset value or preset amount), and a vehicle sensor 17 for detecting the vehicle 3
and is provided.

The components 11 to 14 are connected to the CPLJ 21 via the output 1/F (interface) 20 in FIG. 3, while the components 15 to 17 are connected to the CPLJ 21 via the input I/F 22.
Connected to PLJ21. The CPU 21 is the communication 1/F2
3 and the refueling machine 2 via communication cables 6-1 to 6-K.
-1 to 2-K, accesses each refueling machine 2-i at predetermined time intervals to read the status data 25, and reads the status data 25 from the memory 24.
stored in a predetermined area. As shown in FIG. 3, the status data 25 includes a nozzle switch bit that does not indicate on/off of the nozzle switch of each refueling em2-i, and an area that indicates the preset amount and the refueling amount. In the case of full tank refueling, the full tank data rFLILLJ is entered in the preset amount area. Furthermore, it goes without saying that the amount of oil supplied increases gradually during refueling.

Next, FIG. 4 is a conceptual diagram showing the configuration of the manufacturing section of the memory 24. In this figure, reference numeral 31 is an oil type-specific refueling machine number table that associates oil types that can be refueled with refueling machine numbers that can refuel the oil types. In this embodiment, it is assumed that there are five refueling machines (i.e. = 5), regular refueling machines 2-1 to 2-3, high octane refueling machines 112-4,
It is assumed that gas oil is supplied by fueling machines 2-5, respectively.

32 is a data area, and a preset key 16
The value obtained by dividing the preset value or the preset amount by the unit price is temporarily stored as preset data. Note that the oil tank data area 32 normally stores full tank data rFULmJ, the details of which will be described later.

33 is the unit price data area and is regular.

It consists of areas 33a, 33b, and 33c for storing the price per 1J for each type of oil, such as high-octane oil and light oil.

Next, 35 (35-1 to 35-5> is a selective refueling machine refueling area, which is provided corresponding to each refueling +12-1 to 2-5 and functions as a refueling queue. For example, in the refueling area 35-1 of the i-select refueling machine, there is a
000'' and rFULL'' are stored, indicating that 10J preset refueling and full tank refueling form a holding queue for refueling R2-1.

36 (36-1 to 36-5) is the refueling end area, and when refueling is completed, ll i II, refueling machine 2-
0'' when refueling data is sent to i and a refueling request is issued.
is set to This operation will be explained in detail in Shun.

37 (37-1 to 37-5> is the current status area,
This is an area for storing the latest condition data 25 (FIG. 3) read from the refueling machine 2-i.

Further, 38 (38-1 to 38-5) is a previous state area in which the previous state data 25 is stored.

That is, each time the latest status data 25 is read, the data in the current status area 37 is transferred to the previous status area 38, and the latest status data 25 is set in the current status area 37.

This time, the status data 37 includes on/off of the nozzle switch,
It shows the preset m ([FULLJ in the case of full tank refueling) and the refueling amount. For example, refueling 112-1
(For No. 1 m>, full refueling is currently requested (rFIJLLJ in area 37-1), but the nozzle has not been removed yet (IN Q 1 in area 37-1).
1), therefore the amount of oil supplied is also zero (IJ737-1 (Dr.
OOOOOOJ )r indicates that there is. Also, since the refueling end area 36-1 is II OII,
It can be seen that the above-mentioned full tank refueling has not been completed yet. As already mentioned, in this No. 1 unit 2-1, following the above-mentioned full tank refueling, preset refueling of 1(l) and other full tank refuelings are queued (area 35-1). )
.

On the other hand, for example, in refueling ta2-4 (unit 4),
Since the refueling end area 36-4 is 1'', it can be seen that the refueling has already ended.The contents of the refueling that has ended are shown in the current status area 37-4.In other words, it has been completely completed. Refueling is a full tank (area 37)
-4 rFULLJ), 334 was refueled (same area 3
It can be seen that ``3300J'' in 7-4 has already been fitted with a nozzle ('O'' in the same area 37-4).

Note that in the previous state area 38-4, the nozzle switch bit is "1", which indicates that the nozzle was removed last time. Regarding this No. 4 machine 2-4, next, the full tank data rFULLJ in the leading area of the refueling area 35-4 is sent to the refueling machine 2-4 as refueling data, and the refueling end area 36-4 becomes 0''. Set and latest status data 25 from refueling 1112-4
At the moment when is read, the refueling in area 37-4 is ``0''.
O000J f,:l? The rat is gone.

In such a configuration, when the vehicle 3 shown in FIG. 1 is detected by the vehicle sensor 17, the oil type selection key 15. The preset key 16 becomes settable, and the oil type and preset value are set by the driver's operation. Then, based on this setting, selection of a refueling machine, guidance display, transmission of refueling data to the selected refueling machine, and each refueling 82
-i state data 25 is read.

Each of these operations will be explained below with reference to flowcharts 1 to 7 in FIGS. 5 to 7.

(1) Refuel! 1 selection and guidance display (Figure 5).

When the vehicle sensor 17 (FIG. 2) detects the vehicle 3, setting operations using the oil type selection key 15 and Bricera milk key 16 become possible. Then, the selected oil type (regular,
The refueling 12-i that can refuel (high-octane, light oil) is selected and displayed, and the pre-ret value is read and displayed.

(a) Fuel supply machine selection and display When the oil type selection key 15 is operated, an interrupt occurs to the CPU 21 and is detected in step S2. and,
The set oil type data is read (Step 5P1)
, a refueling machine is selected in the empty refueling Ia selection routine (step 5P2). That is, in step S81 of the empty refueling m selection routine, the refueling machine corresponding to the set oil type data is read from the oil type-specific refueling machine number table 31 in FIG. For example, when regular is selected, refueling machine 2-
1 to 2-3, refueling machine 2 when high octane is selected
-4 are selected respectively.

Next, in step S82, a fueling machine with the minimum number of waiting times is selected from among the fueling machines selected above.

For example, when regular is set as the oil type data, fueling machines 2-1 to 2-3 are selected in step S81,
In step SS2, the selected refueling machine refueling area 3 in FIG.
Referring to the number of queues stored in No. 5, the refueling aircraft 2-2 or 2-3 with the least queue is selected.

In this way, the refueling machine with the least number of waiting times (2-2 in the above example)
and 2-3) are selected, then the refueling machine with the least amount of refueling machines is selected.

t1. In other words, in step S83, the current status area 37-1 of the refueling machine selected above is read out, and in step S84, the remaining amount of refueling is calculated and the refueling machine is selected. In the above example, the preset amount of No. 2 8!2-2 is 301 and the refueling amount is 20, so the remaining refueling amount is 10j, and the selected refueling d refueling area 35-2
Since the next preset amount stored in is 204, the total remaining amount of refueling in the No. 2 machine 2-2 is 30J. On the other hand, the total remaining refueling amount of Unit 3 2-3 is calculated as above,
(50J-10))+20J=601. In this way, in this step S84, 29 Akebono 2
-2 is selected.

In this way, when the refueling machine that is predicted to have the least waiting time (No. 2 1fi2-2 in the example of the pilot) is selected, step S
In S3, the selected refueling machine is displayed. That is,
The lamp for vehicle No. 2 of the vehicle guidance display 11 of the vehicle guidance device 50 is turned on (FIG. 2), and the vehicle guidance lamp 7 of the 29-type vehicle 2-2 is turned on (FIG. 1).

(b) Step S for reading preset data and display number
Returning to step 3, when the setting of the Brichts value is detected (this is done by an interrupt caused by the operation of the 1 key or the ¥ key of the preset key 16), the preset value is read in step SR1, and this is shown as preset data in FIG. is stored in the oil amount data area 32 (step 5R2). For example, 40 as a preset value.
If 1 is set, the oil amount data area 32 will have:
4000 is set as preset data. Note that when a fixed price is set as a preset value, this is divided by the oil type unit price preset in the unit price data area 33 and converted into oil data, which is used as preset data.

In this way, the preset data stored in the oil m data area 32 is stored in the preset amount display 12 of the vehicle guidance device 5.
(Step 5R3).

For example, in the above example, the preset amount display 12 shows 40.0.
0 is displayed.

J3, the above setting operation can be changed until the vehicle sensor 917 is turned off in step S4, and the changed oil type and preset value are processed in the same way as above, and the oil type and preset value are
The latest preset data is stored in the data area 32.

The Bricht data set in the oil amount data area 32 is added to the holding matrix of the selected tanker refueling area 35-1 of the refueler 2-+ selected in (a) above (step S5). In the above example, 4000 is written at position A of the selected refueling machine refueling area 35-2 of the second car 2-2. Then, in step S6, rFLILI is written in the oil amount data area 32 to initialize it.

Finishes the refueling machine selection and guidance display processing.

In addition, if the preset value is not set, the full tank data rFULLJ corrupted and stored in the oil amount data area 32 by the above initialization is transferred to the selected tank refueling machine refueling area 35, and the full tank data is transferred to the selected refueling machine refueling area 35. It will be displayed that the tank is being refueled.

(2) Sending refueling data to each refueling machine (Figure 6).

In parallel with the process (1) above, the CPU 21 performs each refueling m2
-i's refueling status is constantly monitored (this process will be explained in detail in the next section (3)), and whether or not there is a queue in the selected refueling machine refueling area 35-1 of the refueling machine 2-i that has finished refueling. Please check the following step S14. ), when there is a queue, the refueling data of the head of the queue is transmitted to the refueling machine 2-i.

First, in step S11, i is increased by 1 to specify the next refueling 12-i. In the initial state, i = O.
), read out the refueling end area 36-i data of No. 1 R2-1 (step 812), and check whether refueling has ended (step 513). That is, when the data in the refueling end area 36 is "1", refueling is completed, rr.
When it is O++, it is determined that refueling is in progress.

Then, if refueling has been completed, step 814
In step 51, it is checked whether there is a queue in the selected refueling machine refueling area 35-1, and if there is a queue, the refueling data at the head of the queue is sent to the refueling machine 2-1 (step 51).
5). When the transmission is finished, select refueling area 3.
It is impossible to remove the leading refueling data 5-1, and the remaining refueling data are increased in rank one by one to update the holding matrix (step 816). In addition, refueling end area 3 of refueling machine 2-1
6-1 is set to °'0' and the refueling display is displayed (step 517).

In this way, the empty state of the refueling machine 2-1 is checked until 1=K (=5) (step 818), and the empty state of the refueling machine Ia is checked.
The refueling data is transmitted to each refueling f12-i, and after all the refueling data are sent to i=O, step 819) is completed, and the refueling data transmission process to each refueling f12-i is completed.

(3) Reading the status data of each refueling machine (Figure 7).

In parallel with the above processes (1) and (2), the CPU 21
The status data 25 shown in FIG. 3 is sequentially read from each refueling machine 2-1 to check whether refueling has been completed.

First, in step S21 of FIG. 7, i is incremented by 1 to designate the C next fueling machine 2-i.
=Q), No. i n2- The state fQ3 data 25 of i is sent to the current state area 37-1 (step $22). Then, the current state area 37-1 and the previous state area 38-1
(Step 523), it is determined whether refueling has been completed (Step 524). Of course, the nozzle switch bit in the previous status area 38-1 was '1' (the nozzle was disconnected), and the nozzle switch bit in the current status area 37-1 was 'O' (the nozzle was engaged). When , γ11 is determined to be the end of refueling.

For example, in the example shown in Figure 4, the nozzle switch bit in the previous status area 38-4 of No. 4 machine 2-4 is °1'' and that in the current status area 37-4 is "O", so refueling is not possible. It is determined that the process has ended.

When it is determined in step 824 that refueling has ended, "1" is set in the refueling end area 36-1 in step S25, indicating that the refueling person 2-i is in a standby state and waiting for the process in (2) above. to go into. Then, in step 826, the status data 25 in the current status area 37-1 is transferred to the previous status area 38-1. Therefore, at the end of step S26, the current state area 3
The contents of 7-1 and the bamboo garden status area 38-1 are the same, and the next process will be performed.

In this way, the above process is continued until the machine number i becomes K(-5>) (step 527), and all fueling machines 2-1 to 2-5
When the reading of the state data 25 is completed, i=O
(Step 828), and the process of reading the state data of each refueling machine is ended.

Note that the processes (2) and (3) above are repeated at a predetermined cycle by an interrupt from a timer.

As mentioned above, the oil type and oil supply f are determined by the process described in (1).
il (rFULLJ in the case of i+2 tank supply) is set, the refueling data is connected to the queue of the selected refueling machine refueling area 35, and the refueling machine 2-1 whose C refueling has been completed through the process of (3) is detected, and refueling data is sent to the refueling machine 2-1 that has finished refueling through the process (2), and refueling is performed.

Note that as a method for Samurai to find the smallest refueling machine, in the above embodiment, the number of times of waiting (step 582) and the refueling time (step 5S4) are used together, but the full refueling (r
, FULLJ display), the remaining amount of refueling may be calculated using the refueling amount at full refueling as a preset value (for example, 50).

Furthermore, the following modifications are possible without being limited to the above embodiments.

(1) Instead of the oil type-specific refueling machine number table 31, an area storing oil type data may be provided for each refueling machine 2-i. Further, the oil type data can be changed using a setting switch cap (not shown).

(2) In the above embodiment, the oil type and preset value are set using a manual switch such as a key switch, and the refueling guidance is performed using visual means such as a lamp, but it is also possible to use a voice interactive type. In other words, the oil type and preset value may be set by recognizing the voice uttered by the driver, and the refueling guidance may be performed by voice output from the vehicle guidance device.

(3) In addition, in the above embodiment, the vehicle sensor does not automatically create the setting possible state, but the setting switch,
A setting end switch may be provided to allow manual setting.
