Next, the operation of the present embodiment having the above configuration will be described with reference to FIGS.
This will be described with reference to the flowchart of FIG.

◎ Refueling display processing Step SA1: It is assumed that the vehicle that has entered the gas station stops, for example, near the hose 15A (corresponding to the weighing machine No. 9) suspended from the delivery unit 15. Refueling man,
When the hose lowering switch operation cord 19D of the hand controller 18 of the hose 15A is pulled down, the control panel 28
6 is driven to lower the hose 15A at the standby position to the refueling position. At this time, a refueling work start signal (a hose descent signal from the hand controller 18, a hose standby position separation signal from the elevating position detecting means 17, a hose refueling position detection signal, etc.) is supplied to the control panel 28.

Step SA2: The control panel 28 refers to the designated indicator storage table (see FIG. 4 (g)) based on the refueling work start signal, and refers to the automatic designated indicator use data indicating that the indicator 21 is to display the refueling amount. Is transmitted to the indicator control unit 29.

As a result, the refueling display process is temporarily interrupted, and the process proceeds to the display selection process.

◎ Display selection process Step SB1: The indicator control unit 29 receives the designated indicator use desired data (or the special designated indicator use desired data) from the control panel 28 of the weighing machine No. 1.

Step SB2: The indicator control unit 29 confirms whether or not the designation indicator 21 (or the special designation indicator) is in use with reference to the indicator use storage table.

Step SB3: If the designation indicator 21 (special designation indicator) is not in use, the process proceeds to step SB4, whereas if it is in use, the process proceeds to step SB6. The SB3 and the indicator control unit 29 constitute a use state confirmation unit.

Step SB4: Since the designated indicator 21 (or the special designated indicator) is not in use, the indicator control unit 29 sets the area corresponding to the designated indicator 21 (or the special designated indicator) of the indicator use storage table along with the current refueling operation. The fact that the designated indicator 21 (or the special designated indicator) is used by the weighing machine No. 9 (hose 15A) is stored.

Then, after the display of the oil type / hose number display section 26 of the designation indicator 21 (or the special designation indicator) is reset to zero, the oil type and the hose number are displayed on the display section 26.

Step SB5: When the indicator corresponding to the other indicator in the indicator use storage table stores information indicating that the weighing machine is in use by the weighing machine No. 9, the indicator control unit 29 sets a plurality of indicators by one weighing machine. The memory is cleared in order to eliminate the exclusive use. After this, step SB
Move to 6.

Step SB6: The indicator control unit 29 determines the result (indicator No.) that the designated indicator 21 (or the special designated indicator) can be secured as an indicator to be used by the weighing machine No. 9 or the result that the secured indicator cannot be secured. .9 to the control panel 28.

 This returns to the refueling display processing again.

Step SA3: The control panel 28 of the weighing machine No. 9 transmits the transmission result (the secured designated indicator N
o or that the indicator cannot be secured) is displayed on the display unit 19B of the controller 18 at hand.

Step SA4: If the transmission result in step SA3 is “secure designated indicator”, the process proceeds to step SA5, while if the transmission result is “secure impossible”, step SA5
Move to 14.

Step SA5: The control panel 28 permits driving of the pump 31A by the pump driving section 34 in accordance with “securing the designated indicator” in step SA4, and makes the actual refueling operation possible.

Then, the refueling man starts the actual refueling operation by opening the refueling nozzle of the hose 15A of the weighing machine No. 9 when the secured indicator is not bad in visibility by the refueling man or the driver.

On the other hand, when the visibility of the designated indicator is poor for the refueling man or the driver due to the stopping direction of the vehicle, the refueling man operates the indicator selection switch of the hand controller 18.
Operate 19A and select the desired indicator.
In this case, while the refueling man is pressing the indicator selection switch 19A, the indicator No. is displayed on the display section 19B as “1 →
2 → 3 → 4 → 1... ”Is cyclically displayed at predetermined time intervals, and when the finger is released from the switch 19B, the No indicator being displayed is selected and set as the special designation indicator.

Step SA6: The control panel 28 proceeds to step SA7 when the refueling man operates and inputs the special designation indicator No. by the indicator selection switch 19A, and moves to step SA9 when the operation is not performed.

Step SA7: The control panel 28 transmits to the indicator control unit 29 the special designation indicator use request data indicating that the refueling man wants to display the refueling amount by the indicator of No selected and set by the hand controller 18.

As a result, the refueling display process is temporarily interrupted, and the process proceeds to the display selection process. Then, after performing the processing of steps SB1 to SB6 in the display selection processing as described above, the flow returns to the refueling display processing again.

Step SA8: The control panel 28 receives the transmission result (the secured special designation indicator No or the fact that it cannot be secured) from the indicator control section 29 and displays it on the display section of the local controller 18.
Display on 19B. Thereafter, the flow returns to step SA6.

If the designated indicator can be secured but the special designated indicator cannot be secured, the designated indicator or the special designated indicator secured by the previous special designation remains secured.

Step SA9: The control panel 28 detects that the refueling man has started the actual refueling operation by opening the refueling nozzle of the hose 15A based on the flow rate pulse supplied from the flow meter 31B via the flow rate pulse input unit 35. If so, the process proceeds to step SA11. If not detected, the process proceeds to step SA10.

Step SA10: The control panel 28 detects whether or not the current refueling operation has been completed, based on the fact that the actual refueling operation has not been started. If the end of the refueling operation is not detected, it is determined that the refueling operation has been interrupted, and the process returns to step SA6. If the end of the refueling operation is detected, the process proceeds to step SA13.

In this case, the selected indicator can be changed to another indicator until the actual refueling operation is started.

Step SA11: The control panel 28 transmits refueling data such as refueling amount data, oil type data, and hose No data to the indicator control unit 29 based on the detection of the actual refueling work start.

As a result, the refueling display process is temporarily interrupted, and the process proceeds to the display process.

◎ Display process Step SC1: The indicator control unit 29 receives the refueling data from the control panel 28 of the weighing machine No. 9.

Step SC2: The indicator control unit 29 transmits the refueling data to the display drive unit 40 of the indicator, and displays the refueling amount on the refueling amount display unit 25.

The processing in steps SC1 and SC2 is performed until the end of refueling work on the vehicle is detected.

In the refueling display process again, Step SA12: The control panel 28 of the weighing machine No. 9 outputs the refueling work end signal (hose raising signal from the hand controller 18, the hose refueling position separation signal from the lifting / lowering position detecting means 17, the hose standby Based on whether or not a position detection signal or the like is supplied, it is detected whether or not the refueling work for the vehicle has been completed. When the refueling work end is detected, the process proceeds to step SA13, and when the refueling work end is not detected, the process returns to step SA11.

Step SA13: After a predetermined period of time, the control panel 28 transmits to the indicator control section 29 that the use of the reserved designated indicator has been completed. As a result, the refueling display process is temporarily interrupted, and the process proceeds to the display end process.

Note that the predetermined time is set to prevent a problem that the refueling amount display unit 25 of the securing indicator is immediately reset to zero after the refueling of the vehicle is completed, and the refueling amount to the next vehicle is displayed. .

◎ Display end processing Step SD1: The indicator control unit 29 receives a notification from the control panel 28 of the weighing machine No. 9 that the use of the designated indicator (or the special designated indicator) has been completed.

Step SD2: The indicator control unit 29 determines the hose number of the area corresponding to the designated indicator (or the special designated indicator) in the indicator use storage table.
Is cleared, and an empty state is stored in the area.

Again, in the refueling display processing, Step SA14: The control panel 28 of the weighing machine No. 9
Refer to the designated indicator storage table and
It is determined whether or not there is a spare indicator corresponding to A. In this case, since there is no spare indicator, step SA
The process proceeds to 15, but if there is a spare indicator when refueling with another hose, the process returns to step SA2.

Step SA15: The control panel 28 proceeds to step SA17 when the refueling man operates the indicator selection switch 19A of the hand controller 18 to input the No. of the special designation indicator for displaying the refueling amount by the hose 15A. If not, the process proceeds to Step SA16.

Step SA16: The control panel 28 has the special designated indicator No.
Based on the presence or absence of supply of a refueling work end signal (hose raising signal from hand controller 18, hose refueling position separation signal from lifting / lowering position detecting means 17, hose standby position detection signal, etc.) Then, it is determined whether or not the refueling work for the vehicle has been completed. If the refueling operation has been completed, the refueling display process is ended. If the refueling operation has not been completed, the process returns to step SA15.

Step SA17: The control panel 28 transmits, to the indicator control unit 29, use request data indicating that the refueling man wants to display the refueling amount by the special designation indicator of No selected and set by the hand controller 18.

As a result, the refueling display process is temporarily interrupted, and the process proceeds to the display selection process. Then, after performing the processing of steps SB1 to SB6 in the display selection processing as described above, the flow returns to the refueling display processing again.

Step SA18: The control panel 28 receives the transmission result (the secured special designation indicator No or the fact that securing is impossible) from the indicator control section 29 and displays it on the display section 19B of the local controller 18.

Step SA19: The control panel 28 proceeds to step SA5 if the transmission result in step SA18 is "secure the special designation indicator" and permits the drive of the pump 31A, while if the transmission result is "secure impossible", it proceeds to step SA15. Return to
