It has a refueling table in which refueling data representing the refueling amount and refueling state of the weighing machine itself and the other party is written, and further,
The unit price of the oil type used to calculate the billing amount is memorized.

FIG. 2 shows an example of the refueling table TBL provided in the memory of the weighing machine 3-1. In this figure, column (a) is the partner weighing machine refueling complete flag, and when this flag is "0", it indicates that the partner is not refueling or is refueling, and "l"
In case of j, refueling is completed. Column (b) is the self-measuring machine refueling complete flag, and its contents are the same as column (a).

Column (C) is the double refueling flag, and the flag is "0".
In the case of "1", it represents normal refueling, and in the case of "1", it represents double refueling.

It consists of a storage device. A vehicle 6 is shown entering the stand and parked next to the island 7. This vehicle 6 has one side (two fuel tanks 6a,
6b is loaded, and fuel is supplied double (simultaneously) from weighing machines 3-1 and 3-2.

Next, the operation of the refueling metering device I having the above configuration during double refueling will be explained with reference to the flowcharts shown in FIGS. 3 and 4. Now, when the vehicle 6 enters the stand and stops next to the island 7 (see Figure 1), the worker fills the fuel tanks 6a, 6 of the vehicle 6 that entered the stand.
Go to the POS outdoor device 2 to perform double refueling work. Here, the worker confirms that it is possible to input the customer card on the display section of the outdoor POS device 2 (
In step SO in FIG. 3, the card received from the customer is inserted into the card league of the device 2 and read (step S1,). Next, when the worker presses the double refueling key provided on the device 2 (step S
2) The device 2 prompts for the input of the identification number of the weighing machine that starts the double refueling operation first (step S3), and the worker follows this and enters the identification number rlJ of the weighing machine 3-1 into the device 2. Input is made from the numeric keypad (step S4), and the device 2 displays "l" on the display section. After confirming the number, the worker presses the "setting key" (step S

After the above input operations have been performed, the POS outdoor device 2 transmits refueling start data consisting of the identification number and customer number of each weighing machine 3-1, 3-2 that performs double refueling to the POS device via the data transmission line 5. Send to 4.

Here, each of the weighing machines 3-1, 3-2 intercepts the refueling start data sent from the POS outdoor device 2 to the POS device 4, and learns that double refueling will be performed. Next, the POS device 4 that has received this refueling start data determines whether the data is appropriate (step S9), and sends the determination result back to the outdoor POS device 2 via the data transmission line 5. And P
If the returned judgment result is rNGJ, the outdoor OS device 2 displays to the worker that the input is incorrect (step SIO), and also sounds a buzzer to notify the worker of the incorrect input (step SIO). 611), the process returns to the initial state (step SO), and if the determination result is rOKJ, the process proceeds to step S12. In step St2, PO
The outdoor device 2 for S uses a weighing machine 3-1.3-2 for the worker.
A lamp lights up to let you know when refueling is possible. Here, the weighing machine 3-1, which has been set to perform the double refueling operation first (see step S4), sends a double refueling instruction command to the other weighing machine 3-2 to instruct the start of double refueling.

Next, after confirming that the refueling ready lamp on the outdoor POS device 2 is lit, the worker moves to the weighing machine 3-1 to perform double refueling work.
Go to the fuel tank 6a of the vehicle 6 from the weighing machine 3-1.
The refueling nozzle is set to the refueling port of the metering machine 3-1.
-2 double refueling operation is performed.

Next, the operation of each weighing machine 1-1, 3-2 during double refueling will be explained with reference to the flowchart shown in FIG. First, each weighing machine 3-1.1-2 at the time when the power is turned on by the worker initializes the program loaded by each weighing machine at the same time as the power is turned on, and then performs a step S.
Proceed to 40.

In step S40, it is determined whether there is a command from another weighing machine, but at this point, the determination result is rNOJ, and the process advances to step S41. Step S
In step 41, it is determined whether the timer value (2 seconds) for timing management to periodically send refueling data to the other party's weighing machine has timed out, but the determination result at this point is rNO Go, and step Proceed to S42. In step S42, it is determined whether or not its own refueling has been completed, but the determination result at this point is rNOJ, and the process advances to step S43. In step S43, it is determined whether both the own and the other party's weighing machines have completed refueling, but the determination result at this point is rNOJ, and the process returns to step S40. In this way, each weighing machine 3-1.3-2
The above-described series of judgments is repeated from the time the power is turned on until the refueling operation starts.

Now, if double refueling is performed, that is,
Each weighing machine 3-1.3-2 is connected to P
The weighing machine 3-! intercepts the refueling start data sent to the OS device 4, recognizes that double refueling is to be performed, and is set to perform the double refueling operation first (see step S4 in FIG. 3)! When the double refueling instruction command is sent to the other party's weighing machine 3-2 to instruct the start of double refueling,
The determination result in the above step S40 of total 1i1113-2 is rYEsJζ, and the process advances to step S44.

In step S44, it is determined whether the command sent from the other party's weighing machine 3-1 is a double refueling instruction command. In this case, the judgment result is rYES.
J, and the process advances to the next step S45. Here, also in the weighing machine 3-1 that sent the double refueling instruction command,
After sending the command, the process advances to step S45. Step S
At 45, the measurement # that received the double refueling instruction command! 1
3-2 and the weighing machine 3- that sent the double refueling instruction command
1 writes the data (weighing machine number and double refueling flag of the other party) received or sent along with the command to (c) and (d) Mfl of their respective refueling tables TBL, and proceeds to the next step S46. Step S46
Now, we will set the timer value (
2 seconds) and proceeds to step S47.

Next, each weighing machine 3-1.3-2 during double refueling receives a command from the other weighing machine, such as a refueling amount report command or a refueling completion command, so the judgment in step S40 described above is made. The result is rY E S J, and the process advances to the next step S44.

In step S44, since double refueling has already been performed, the judgment result is "NO" and the process proceeds to step S47.In step S47, it is determined whether or not the received command is a refueling! report command. Judgment result is rY
If the result is EsJ, the process advances to the next step 548, and if the result is rNOJ, the process advances to step S51. In step S48, the data representing the amount of refueling received along with the refueling amount report command is written into (e)I of its own refueling table TBL, and the process proceeds to the next step S49. Step S49
Now, column (f) and (e) 11 of the refueling table TBL.
11, that is, read out the refueling amounts of the self and the other party, calculate the total value of double refueling (total refueling amount), write it in (g)lf11 of the table TBL, and proceed to the next step S5
Go to 0. In step S50, the respective refueling amounts and total refueling amounts are read from the (f) column and (g) column of the refueling table TBL, and the billing amount based on the unit price is calculated,
The amount of refueling and the billed amount are displayed on its own display device in the display format shown in FIG. Here, (a) in the figure shows the display format of the own fuel supply amount and the billed amount, and (b) shows the display format of the total fuel supply amount and the billed amount. Note that the calculation of the own refueling amount and the billed amount is performed by a counter installed in the own control device that can operate independently of this operation (for example,
(hard counter, etc.). Further, each display value of this display device is reset to zero during refueling work by removing the refueling nozzle from a predetermined storage position and closing the nozzle switch.

On the other hand, if the determination result in step S47 is rNOJ, the process proceeds to step S51, where it is determined whether the command from the other party's weighing machine is a command indicating completion of refueling,
If this judgment result is rYESJ, the next step S
If the result is "NO", proceed to step S
Proceed to 41. In step S52, a flag rN indicating that the other party's weighing machine has completed refueling is written in column (a) of its own refueling table TBL, and the process advances to step S41.

In step S41, t is set in step S46 above.
Each timer value (can be set arbitrarily in advance, for example 2
If the judgment result is rYESJ, that is, the timer value (2 seconds)
If the determination result is rNOJ, the process proceeds to the next step S53, and if the determination result is rNOJ, the process proceeds to step S42. In step S53, (c)I of its own refueling table TBL
It is determined whether or not the state is in the double supply state, and if the result of this determination is rYESJ, the process proceeds to the next step S54, and if the result is rNOJ, the process proceeds to step S42. .In step S54, a control device provided in the control device that can operate independently of its own above-mentioned main operation,
The current amount of refueling stored in the counter that calculates the amount of refueling each time a flow rate pulse is output from the flow rate transmitter is written in the column (O) of the refueling table TBL, and the process advances to the next step S55. In step S55, the table TBL
The refueling amount written in column (r) is read out and sent to the other party's weighing machine, and the process advances to step S42.

Next, for example, weighing machine 3-! When the operator completes refueling the fuel tank 6a, the worker removes the refueling nozzle from the refueling port of the tank 6a and returns it to a predetermined position. Here, total 1
In step S42, #3-1 determines whether or not its own refueling has been completed, that is, whether or not it has detected a nozzle return signal issued from its own nozzle switch. In this case, the determination result is rY E If the result is rNOJ, the process advances to step S43. In step S56, a flag rlJ indicating that refueling has been completed is written in column (b) of its own refueling table TBL, and the process proceeds to the next step S57. In step S57, a refueling completion command is sent to the other party's weighing machine, and the process proceeds to the next step S58. In step S58, the own refueling amount and refueling completion flag, that is, the data in the (ram and (b) column) of the refueling table TBL are read and sent to the POS device 4, and the next step S43
Proceed to.

Next, when the weighing machine 3-2 also completes refueling into the fuel tank 6b, the processes from step S42 to step S5g described above are performed in the same manner, and the process proceeds to step S43. Then, in step S43, it is determined whether or not both the weighing machine itself and the other party have completed refueling, that is, the refueling table TB
The flags in column (a) and (b) fill of L I are both rl

By the way, the data sent to the POS device 4 in the above-mentioned step 558 (its own refueling complete flag and its own refueling amount) is stored in the Uiro storage device (not shown) of the device 4 at the time when the above-mentioned series of double refueling processes are completed. (omitted),
The data is stored as data for sales management.
