[0008]
Next, an embodiment in which all optional devices are added to the standard specification oil supply device 1 will be described with reference to FIG. The self-console 20 that is the first optional device is connected to the first connection terminal 4a. The self-console 20 is necessary for a gas station where self-service is used, and is installed in the office of the gas station. Then, a refueling request signal is output from the refueling control device 4 to the self-console 20, and the refueling control device 4 receives the refueling permission signal from the self-console 20 so that the refueling device 4 can be refueled.
[0009]
The oil type correctness determination device 21 as the second optional device is connected to the second connection terminal 4b. The oil type correctness determination device 21 is provided in the fuel supply nozzle 10 and determines whether the oil type supplied from the oil supply device 1 is correct and the oil type in the fuel tank of the automobile. Accordingly, the oil supply control device 4 can receive the correct oil type signal from the oil type correct / incorrect determination device 21 so that the oil supply device 1 can be in an oilable state.
[0010]
The engine stop determination device 22 of the automobile, which is the third optional device, is connected to the third connection terminal 4c. The engine stop determination unit 22 ensures the engine stop of the automobile to ensure safety during refueling. For example, when the engine key is put, an engine stop signal is output, and the fuel supply control device 4 receives the engine stop signal and supplies the fuel supply device. 1 can be in a refuelable state. The engine stop determination unit 22 may detect an engine sound or vibration of the automobile and output an engine stop signal.
[0011]
The vibration detector 23, which is a fourth optional device, is connected to the fourth connection terminal 4d. The vibration detector 23 is for ensuring safety in the event of a car crash or earthquake, and outputs a vibration sensing signal when a certain level of vibration is applied.

[0014]
The alarm 30 that is the seventh optional device is connected to the seventh connection terminal 4g. The notification device 30 notifies an erroneous operation of the oiler, and operates upon receiving an operation signal from the fuel supply control device 4.
[0015]
Next, the operation of the fueling apparatus 1 to which all optional devices are added will be described based on the flowcharts of FIGS. The car is stopped in front of the refueling device 1, the engine key is placed on the engine stop determining device 22, the customer's refueling card is read by the card reader 27 of the refueling data input / output device 26, and the refueling nozzle 10 is placed on the nozzle 12 If it is removed, an ON signal is input from the nozzle switch 13 to the fuel supply control device 4 (FIG. 3 ST1), an engine stop determination device 22 is added (FIG. 3 ST2), an engine key is placed, and the engine stop determination device 22 Since the engine stop signal is input (FIG. 3, ST3), the process proceeds to the next step ST4. Since the self-console 20 is added (FIG. 3, ST4), a fuel supply request signal is output to the self-console 20 (FIG. 3, ST5). When the refueling manager confirms safety and operates the self-console 20 to input a refueling permission signal from the self-console 20 to the refueling control device 4 (ST6 in FIG. 3), the oil type correctness determination device 21 is added ( 3 ST7), the process proceeds to the next step ST8. When the oil supply nozzle 10 is inserted into the oil supply port of the automobile, the correctness of the oil type in the oil supply port and the oil type to be supplied is determined, and the correct oil type signal is input from the oil type correct / incorrect determination device 21 (ST8 in FIG. 3). The display of the previous oil supply amount displayed on the amount indicator 14 is returned to zero, the motor 6 of the pump 7 is started (ST9 in FIG. 3), and the oil supply device 1 is ready for oil supply.
[0016]
If the engine key is not placed on the engine stop determination device 22 and an attempt is made to supply fuel, the engine stop signal is not input to the fuel supply control device 4 when the oil supply nozzle 10 is removed from the nozzle hook 12 ( FIG. 3 ST3), the alarm 30 operates (FIG. 3 ST10). When refueling is dangerous, a refueling disable signal is input from the self-console 20 (FIG. 3, ST6), and the alarm 30 is activated (FIG. 3, ST10). Further, if the oil type in the oil supply port is different from the oil type to be supplied, an incorrect oil type signal is input from the oil type correct / incorrect determination device 21 (FIG. 3 ST8), and the alarm 30 is activated (FIG. 3 ST10). ). Then, when these erroneous operations are noticed by the operation of the alarm device 30 and the fuel supply nozzle 10 is put on the nozzle hook 12 and an off signal is input from the nozzle switch 13 (ST11 in FIG. 3), the fuel supply control device 4 stops the alarm device 30 ( FIG. 3 ST12).
[0017]
When refueling is started and a flow rate pulse is input from the flow rate pulse transmitter 8 of the flow meter 9 to the refueling control device 4 (FIG. 4 ST1), this flow rate pulse is counted and displayed on the refueling amount display 14 (FIG. 4). ST2). And since the refueling limit amount (for example, 90 liters) is stored (FIG. 4 ST3), if the current refueling amount is equal to or less than the refueling limit amount (FIG. 4 ST4), the refueling limit time (for example, 5 minutes) Is stored (FIG. 4 ST5), and if the refueling time up to the present is within the refueling limit time (FIG. 4 ST6), the refueling is finished and an OFF signal is input from the nozzle switch 13 (FIG. 4 ST7). These steps ST1 to ST7 are repeatedly executed.
[0018]
When the desired amount of refueling is completed, the refueling nozzle 10 is hung on the nozzle hook 12 and an off signal is input from the nozzle switch 13 to the refueling control device 4 (FIG. 4 ST7), the motor 6 of the pump 7 is stopped and the refueling data is stored. It is output to the self-console 20 (FIG. 4, ST8).
[0019]
In addition, when the fuel tank of the car is full and the refueling is continued up to the refueling limit without noticing that the oil is overflowing (ST4 in FIG. 4), the motor 6 of the pump 7 stops and the alarm 30 operates (FIG. 4, ST9). In addition, when the refueling has been extended for a long time (FIG. 4 ST6), the motor 6 of the pump 7 is stopped and the alarm 30 is activated (ST9 in FIG. 4). Then, when these erroneous operations are noticed by the operation of the alarm 30 and the oil supply nozzle 10 is put on the nozzle hook 12 and an off signal is input from the nozzle switch 13 (FIG. 4, ST10), the fuel supply control device 4 stops the alarm 30 ( FIG. 4 ST11).
[0020]
In addition, when the engine stop determination device 22 is not added (FIG. 3 ST2), when the self-console 20 is not added (FIG. 3 ST4), when the oil type correctness determination device 21 is not added (FIG. 3 ST7). ) When the refueling limit amount is not stored (FIG. 4 ST3), when the refueling limit time is not stored (FIG. 4 ST5), steps ST3, ST5, ST6, ST8 of FIG. 3 and step of FIG. The next step is executed without executing ST4 and ST6.
[0021]
Further, as shown in the flow chart of FIG. 5, when the vibration detector 23 is added (FIG. 5 ST1) and a vibration detection signal is input from the vibration detector 23 due to an earthquake or the like (FIG. 5 ST2), the oil supply control device 4 locks the motor 6 of the pump 7 to make the oil supply device 1 incapable of oil supply, and operates the alarm 30 (ST3 in FIG. 5). Thereby, in the case of refueling, refueling stops and dangers, such as a fire outbreak, can be prevented beforehand.
[0022]
