EMBODIMENT OF THE INVENTION Next, the form for implementing this invention is demonstrated in detail, referring drawings.

FIG. 1 shows first and second embodiments of a gas station system according to the present invention. This gas station system 1 includes a human body/vehicle sensor 2a and a BLE (Bluetooth Low Energy) beacon (radio wave transmitting means, hereinafter 2b, an identification code reader 2c, and a server 3 forming a cloud. The fueling device 2 and the server 3 can communicate with each other. Further, the fueling device 2 and the server 3 can communicate with the mobile terminals 4 (4A, 4B) used by customers in the fueling area. The gas station system 1 also includes a settlement device (not shown) for the customer to settle after refueling.

The human body/vehicle sensor 2a is provided as a power saving measure so that the beacon 2b emits radio waves only when a visitor arrives.

The directivity and communication distance of the beacon 2b of the fueling device 2 (2A, 2B) are limited to the fueling area near the fueling device 2, but the mobile terminals 4 (4A, 4B) of the customers in this fueling area have both radio waves from the beacons 2b of the fueling devices 2A and 2B. It should be noted that any transmitting means (wifi, etc.) that can communicate with the mobile terminal 4 can be used instead of the beacon.

As shown in Table 1, the server 3 stores customer ID, oil type, oil supply method, and oil supply setting data related to the payment method, and oil supply data (such as the amount of oil supplied when the vehicle is filled with oil). While accumulating, management of gas station sales data is performed based on refueling data.

The mobile terminal 4 is a smartphone, tablet, or the like owned by the customer, and has a function of communicating with the fueling device 2 and the server 3, a function of displaying fueling data, a fueling slip, and the like. If the mobile terminal 4 can display the fueling slip, it is preferable because the equipment investment for printing the fueling slip can be reduced at the gas station.

Next, the operation of the first embodiment of the gas station system 1 having the above configuration will be described with reference to FIGS. 1 and 2. FIG. In addition, the customer registers in advance the customer ID, oil type, refueling method, and refueling setting data regarding the settlement method in the server 3 via an application or the like of the mobile terminal 4 . It is also assumed that the beacon ID from the beacon 2b of the fueling device 2 and the number of the fueling device 2 are associated and recorded in the server 3 . In the step in which the route branches in FIG. 2, the downward direction corresponds to Yes, and the horizontal direction corresponds to No.

In step S1 of the fueling device 2A and step S81 of the fueling device 2B, when each human body/vehicle sensor 2a detects a customer (step S1; Yes, S81; Yes), the beacon ID is output from the beacon 2b (step S2, S82). When the beacon ID is input from the fueling devices 2A, 2B to the mobile terminals 4A, 4B (step S21; Yes, step S61; Yes), a push notification as shown in FIG. 3A is sent to the mobile terminals 4A, 4B. displayed (steps S22, S62). Here, it is assumed that the beacon ID is input to the mobile terminal 4A from the fueling device 2B, and the beacon ID is input to the mobile terminal 4B from the fueling device 2A.

After the display of FIG. 3A, when the customer using the mobile terminal 4A touches the display screen (step S23; Yes), the beacon ID and the customer ID of the refueling device 2B are output from the mobile terminal 4A to the server 3. (Step S25). If the customer does not touch the display screen of the mobile terminal 4A and inputs cancellation (step S24; Yes), the display screen of the mobile terminal 4A shows that the process has been canceled (step S34). The operation of the mobile terminal 4A ends.

When the beacon ID and customer ID of the fueling device 2B are input from the mobile terminal 4A to the server 3 (step S41; Yes), the server 3 outputs a fueling setting data display signal to the mobile terminal 4A (step S42). When 4A receives this signal (step S26; Yes), the fueling device number (fueling device: 2B) and customer's fueling setting data as shown in FIG. 3(b) are displayed on the display screen of portable terminal 4A. .

Confirm that the fueling device planned to be used by the customer is 2B and that it matches the fueling device number (fueling device: 2B) displayed on the mobile terminal 4A, and that the fueling setting data, etc. are correct. When "YES" on the display screen of the mobile terminal 4A is touched (step S28; Yes), a fueling request signal is output from the mobile terminal 4A to the server 3 (step S29), and when the server 3 receives this (step S43; Yes), the server 3 transmits a cancel signal to the mobile terminal 4B (step S44), and when the mobile terminal 4B receives this (step S64), the display screen of the mobile terminal 4B shows the message shown in FIG. , a message indicating that the processing has been canceled is displayed (step S74), and the operation of the portable terminal 4B is terminated.

Next, when the server 3 outputs a fueling permission signal to the fueling device 2B (step S45), and the server 3 inputs the fueling permission signal to the fueling device 2B (step S83; Yes), the fueling setting is performed in the fueling device 2B. done. Further, as shown in FIG. 3(c), the display screen of the portable terminal 4A displays a message indicating that refueling is to be started.

At step S84, when the customer removes the fuel nozzle from the nozzle hook and the nozzle SW (switch) of the fueling device 2B is turned ON (step S84; Yes), at step S85 , the oil type input at step S83 is handled. If the correct fuel nozzle has been removed (step S85; Yes), a reset signal is sent to the display of the fueling device 2B, indicating that the previous fueling has been performed. The information is reset to zero and the fuel pump is turned on (step S87).

On the other hand, if the customer has removed the wrong fuel nozzle in step S85 (step S85; No), the customer is notified to check the fuel nozzle through a display or the like (step S86).

In step S87, when the fuel pump is turned on, the fuel oil is discharged from the fuel nozzle, whereby a flow rate pulse signal is output to the display (step S88; Yes), and the display shows the amount of fuel supplied (count display). is performed (step S89). If the flow rate pulse signal is not output (step S88; No), output of the flow rate pulse signal is waited unless the nozzle SW is turned off (step S90; NO), that is, until the refueling is stopped or completed.

When refueling based on the refueling setting input in step S83 is completed, the refueling pump is turned off (step S91), and refueling data is output to the server 3 (step S92).

In step S46 of the server 3, when the refueling data is input from the refueling device 2B (step S46; Yes), after generating the refueling data from the refueling data, refueling and reimbursement data is output to the portable terminal 4A (step S47).

In the mobile terminal 4A, when the refueling/accounting data is input from the server 3 (step S30; Yes), both data are displayed on the display section so that the customer can confirm both data (step S35). After that, when the display time T of both data reaches the predetermined time t1 (step S36; Yes), it is determined that the confirmation of the customer is completed, and the refueling/accounting data is output to the server 3 (step S37).

In the server 3, when the refueling/settlement data is input from the mobile terminal 4A (step S48; Yes), a settlement processing completion signal is output to the mobile terminal 4A (step S49). This completes the operation of the server 3. When the settlement processing completion signal is input from the server 3 in the mobile terminal 4A (step S38; Yes), the fueling slip is displayed (step S39). This completes the operation of the portable terminal 4A and the fuel supply operation.

When the human body/vehicle sensor 2a stops detecting the customer (step S13; Yes, step S93; Yes), the fuel supply devices 2A and 2B stop outputting the beacon ID from the beacon 2b (steps S14 and S94). This completes the operation of the lubricating devices 2A and 2B.

On the other hand, in step S27 of the mobile terminal 4A, if the fueling device number displayed on the display screen of the mobile terminal 4A is different from the number of the fueling device to be used (for example, the display screen of the mobile terminal 4A is shown in FIG. 3 ( b), "fueling device number: 2B" is displayed, but the customer plans to use the fueling device 2A), when the customer presses the reacquisition button (S31; , the beacon ID is input from the beacon 2b of each of the fueling devices 2A and 2B, the process returns to step S25, and the above operations are repeated. As a result, the desired fuel supply can be reliably performed without erroneously specifying the fuel supply device 2A, 2B used by the customer.

The mobile terminal 4B performs the same operation as the mobile terminal 4A, but a push notification as shown in FIG. 3A is displayed (step S62), and then the customer of the mobile terminal 4B touches the display screen. (Step S63; Yes), even if the fueling device number and the customer's fueling setting data as shown in FIG. YES" is not touched (step S68; No) and "re-acquire" is not touched (step S71; No), as shown in FIG. After that, the process ends.
