Abstract

PROBLEM TO BE SOLVED: To perform setting operation of each oil supply apparatus by means of a remote controller. SOLUTION: A control circuit for metering devices 17 (171-17n) registers an individual setting changing value for an oil supplying nozzle transmitted from a remote controller when nozzle removal detecting switches are off. In addition, when all the nozzle removal detecting switches are on, the individual setting changing value for the oil supplying nozzle transmitted from the remote controller is made out of object. Therefore, even if a plurality of metering devices 171-174 are installed at adjacent positions, the initial setting processing is performed only in the metering device 171 where the oil supplying nozzle is taken off from a nozzle hanger. Therefore, the initial setting signal by the remote controller 32 is prevented from being set in the adjacent metering device by mistake.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fueling device, and more particularly to a fueling device in which individual information is set for each of a plurality of fueling devices.

[0002]

2. Description of the Related Art For example, a gas station or the like is provided with a plurality of weighing machines (oiling devices). Each weighing machine is provided with a refueling nozzle for regular gasoline, high-octane gasoline, and light oil. In such a gas station,
When the customer's car arrives to refuel, the driver himself inserts a fuel nozzle of an oil type according to the engine specifications into the fuel tank filler port and fills the fuel tank with the oil liquid stored in the underground tank. Refueling, so-called self-service refueling, is being considered.

[0003] When self-service refueling is performed at a gas station, a driver who enters the gas station moves to the fueling area of the weighing machine without the guidance of an operator, stops the vehicle in front of the weighing machine, and drives the vehicle. Perform the refueling work by himself. Each weighing machine is managed by a POS system. When refueling data such as an oil type to be refueled, a refueling amount, and a payment method is input by a setting device, a refueling permission signal is output from the POS terminal and the refueling is performed. Refueling at points becomes possible. Thereafter, when the refueling nozzle of the oil type to be refueled is removed from the nozzle hook, the pump of the oil type is started, and when the refueling is completed and the refueling nozzle is returned to the nozzle hook, the pump stops.

In the POS system, when refueling data is transmitted from the weighing machine to the POS terminal after refueling is completed,
P set up at the gas station office etc. for refueling fee settlement
The OS terminal issues a slip describing refueling data such as refueling amount, refueling oil type, refueling fee, and the like. Then, the customer who has completed the self-service refueling pays the refueling fee described on the slip at the checkout office of the office and leaves the refueling station.

As described above, a weighing machine in which self-service refueling is performed is provided with a receiving unit that receives a signal transmitted from a wireless remote controller. Development is underway so that operations such as setting can be performed.

[0006]

However, when a signal is sent to a weighing machine using a remote controller to perform an operation or setting as described above, the signal transmitted from the remote controller is installed before and after the weighing machine. However, there is a problem that other weighing machines that have been received are also received at the same time.

[0007] Therefore, when a signal transmitted from the remote controller is received by a plurality of weighing machines, for example, not only weighing machines not ready for refueling can be refueled, but also one weighing machine and the next weighing machine can be refueled. There is a problem that the initial settings are the same even though the nozzle numbers and refueling oil types are different between the machines. Therefore, an object of the present invention is to provide a refueling device that solves the above problems.

[0008]

The present invention has the following features to solve the above-mentioned problems. The invention according to claim 1 includes a control unit that controls refueling, a receiving unit that receives information transmitted from an external transmitter, and a setting unit that sets information received by the receiving unit in the control unit. In a plurality of refueling devices provided at a gas station, the setting unit sets information received by the receiving unit to the control unit when detecting that a refueling nozzle has been removed from a nozzle hook. It is characterized by the following.

Therefore, according to the first aspect of the present invention, the information received by the receiving unit is set in the control unit when it is detected that the refueling nozzle has been removed from the nozzle hook. The information received by the receiving unit can be set only for the fueling device from which the nozzle is removed, and is not set even if the same information is received by another fueling device adjacent to the surroundings. Therefore, even if the information transmitted from the external transmitter is received simultaneously by a plurality of refueling devices, the information can be set only by the refueling device.

The invention according to claim 2 is a control unit for controlling refueling, a receiving unit for receiving information transmitted from an external transmitter, and transmitting the information received by the receiving unit to the control unit. In a refueling device provided in a plurality of gas stations having setting means for setting, a display means for displaying a unique identification symbol is provided, and the setting means is configured such that the identification symbol displayed on the display means is transmitted to the receiving unit. The information received by the receiving unit when input is set in the control unit.

Therefore, according to the second aspect of the present invention, the fueling device is provided with a display means for displaying a unique identification symbol, and when the identification symbol displayed on the display means is inputted to the receiving section, the receiving section is provided. Is set in the control unit. Therefore, even if the same information is received by another fueling device adjacent to the surroundings, the identification code is different, so that the information is not set.
Therefore, even if the information transmitted from the external transmitter is received simultaneously by a plurality of refueling devices, the information can be set only by the refueling device.

As shown in FIG. 6, the customer arriving at the gas station moves to an empty fueling point among fueling points No. 1 to No. 8 in (operation 10). Then, the vehicle is stopped at an empty refueling point. Next (Action 1)
In 1), the refueling conditions such as the type of oil to be refueled, the amount of refueling, and the payment method are set using the setting unit 25 of the self-service unit 18 installed at the refueling point.

In the next (operation 12), after the setting is completed, the customer himself removes the fueling nozzle 27 from the weighing machine 17 and inserts the discharge pipe of the fueling nozzle 27 into the fueling port of the vehicle. Then, in (operation 13), refueling is terminated, and the refueling nozzle 27 is returned to the weighing machine 17. Further, the customer carries the temporary slip issued from the printer 26 in (operation 14) and goes to a checkout station to settle the refueling fee. Then, in (operation 15), the customer leaves the gas station.

The self-service unit 18 executes the following processing in conjunction with the customer (operations 10 to 15). That is, when the customer enters the refueling point, the self-service unit 18 enters a standby mode of waiting for a setting start in step S11 (hereinafter, “step” is omitted). In this case, the weighing machine 17 may be provided with some vehicle detection device, and the signal may be received by the self-service unit 18. However, the setting may be awaited when the previously refueled vehicle leaves the refueling point.

When the customer finishes the setting operation, S1
At 2, the set value is transmitted to the gas station control device 13. The printer 26 receives a print command from the gas station control device 13 in S13, and issues a temporary slip on which the slip number and the like are printed in accordance with the set format. In addition, (operation 1)
The gas station control device 13 executes the following processing in conjunction with 0-15). That is, the gas station control device 13
Is the setting unit 2 of the self-service unit 18 in S14.
When various settings are transmitted from 5 and the permission button 59 is turned on, the fueling permission is given to the weighing machine 17.

In the next step S15, when the refueling end and the refueling amount are transmitted from the weighing machine 17, the total amount is calculated. Then, in S16, the amount, the slip number, and the like are transmitted to the printer, and printing is instructed. On the other hand, in the weighing machine, when the refueling permission is obtained from the refueling station control device 13 in S17, the waiting time starts from the refueling start. In S18, when the customer starts refueling, the pump is operated, and fuel is supplied from the refueling nozzle 27 to the fuel tank of the vehicle. In the next S19, when the customer finishes refueling, the pump is stopped, and the refueling end and the refueling amount are transmitted to the gas station control device 13.

When refueling is completed, the customer uses the printer 26 of the self-service unit 18 to supply refueling data such as a refueling point number or a weighing machine number, an additional number (a slip number), a date and time, an oil type, a refueling amount, and a refueling amount. Take the temporary slip with displayed and move to the checkout office in the office. The operation procedure for performing self-service refueling is now completed. The setting contents input by the setting unit 25 of the self-service unit 18 are simultaneously displayed on the display device 4 of the gas station control device 13.

Thereby, the presence or absence of the setting of each of the weighing machines 17 _{1 to} 17 _n and the setting contents can be confirmed.

Further, the staff at the gas station receives the temporary slip from the fueling customer and selects data corresponding to the contents from the screen displayed on the display device 46 of the gas station control device 13,
The payment operation is performed by the input device 47. Thus, the refueling data is transmitted from the gas station control device 13 to the POS terminal 15. As a result, a slip is issued from the printer (not shown) of the POS terminal 15, and the slip is handed to the customer in exchange for the refueling fee.

[0043] Here, a description will be given of an operation procedure for initializing the individual information of each of the weighing machine 17 _1-17 every _four. As each weighing machine 17 _{1-17 4} is installed in gas stations, maintenance worker, the initial individual information of the type of oil and the nozzle number of each filling nozzle 27a~27d each weighing machine 17 _{1-17 4} Must be set.

When the installation of the weighing machines 17 _{1 to} 17 ₄ is completed, the maintenance worker completes the operation of each of the weighing machines 17 _{1 to} 174.
To perform an initial setting for each _{1-17 4,} by pressing the "setting key" on the remote controller 32 transmits an individual setting request signal to the weigher 17. FIG. 9 shows each weighing machine 17.
It is a flowchart of an initial setting processing control circuit 37 of _{1-17 4} performs.

As shown in FIG. 9, the control circuit 37
In S21, it is checked whether or not the individual setting request signal transmitted from the remote controller 32 has been received.
In S21, when the individual setting request signal transmitted from the remote controller 32 is received, the process proceeds to S22.
Then, the state of the nozzle attachment / detachment detection switches 30a to 30d provided on the nozzle hooks 29a to 29d is checked. Then, in the next S23, the nozzle attachment / detachment detection switch 3
Check whether 0a-30d is off.

In S23, when one of the nozzle attachment / detachment detection switches 30a to 30d is off, one of the refueling nozzles 27a to 27d is
Since it has been removed from d, the process proceeds to S24, and the individual setting change value (information such as the nozzle number and the oil type) of the refueling nozzle 27 transmitted from the remote controller 32 is registered. For example, the first refueling nozzle 27a is a regular gasoline,
The third refueling nozzle 27b registers high-octane gasoline, the third refueling nozzle 27c registers light oil, the fourth refueling nozzle 27d registers kerosene, and the like.

In S23, when all the nozzle attachment / detachment detection switches 30a to 30d are on,
Proceeding to S25, the individual setting change values (information such as the nozzle number and the oil type) of the refueling nozzle 27 set by the remote controller 32 are excluded. Thereby, when the refueling nozzle 27 is not removed from the nozzle hook 29,
Since the weighing machine 17 is not in the initial setting mode,
Do not perform the initial setting process.

[0048] Thus, only the initial setting of a plurality of weighing devices 17 ₁ to 17 ₄ the weighing machine 17 ₁ be installed fueling nozzle 27 is detached from the nozzle seat 29 to a position where the close is performed, otherwise weigher 17 _{2-17 4} setting be received set signal from the remote controller 32 processing is not performed. Therefore, a plurality of weighing machines 17 ₁ to 1
In 7 _4, the initial setting signal by the remote controller 32 is received as an individual setting change value to the adjacent weighing machine incorrectly is prevented.

Next, a description will be lubrication control process by the control circuit 37 of each weighing machine 17 _{1-17 4} performs. FIG.
Is a flowchart of a process for controlling the setting operation by the control circuit 37 of each weighing machine 17 _{1-17 4} performs. FIG.
As shown, the control circuit 37 of each weighing machine 17 _{1-17 4} is a S31, it is checked whether the remote signal transmitted from the remote controller 32 is received, is provided on the weighing machine 17 ₁ When the receiver 33 receives the remote signal, the process proceeds to S32. In S32, it is checked whether or not the nozzle attachment / detachment detection switches 30a to 30d are turned off.

In S32, if one of the nozzle attachment / detachment detection switches 30a to 30d is off, the process goes to S3.
Proceeding to 3, it is confirmed whether or not the content of the signal received by the receiver 33 is a refueling permission. Here, when the "Allow key" on the remote controller 32 is pressed, sets the fuel supply permission of the weighing machine 17 ₁ in S34. Now, it is possible to fueling in the weighing machine 17 _1.

Next, in S35, a normal refueling process is performed. Then, in S36, it is checked whether the nozzle attachment / detachment detection switch 30 is turned off. In S36, when the refueling nozzle 27 is returned to the nozzle hook 29 and the nozzle attachment / detachment detection switch 30 is turned off, it is determined that refueling has been completed, and the current process is terminated. In addition, S3
In 3, if the signal transmitted from the remote controller 32 is not the permission signal, the flow shifts to S37 to check whether the content of the remote signal indicates that refueling is stopped. In S37, when the content of the remote signal is not the refueling stop,
It returns to said S31.

However, in S37, when the content of the remote signal received by the receiver 33 indicates that refueling is stopped,
The procedure proceeds to S38, to set the refueling stop of the weighing machine 17 _1, and the current processing is terminated. In S32, when all the nozzle attachment / detachment detection switches 30a to 30d are on, the refueling nozzles 27a to 27d
29d, and the process proceeds to S39. And S3
In step 9, if the “all stop key” of the remote controller 32 is pressed, the refueling stop is set in S40, and the process returns to S31.

In the above description, the processing executed when the control circuit 37 provided in the weighing machine 17 ₁ receives a remote signal from the remote controller 32 by the receiver 33 has been described. running the same processing even control circuit 37 of _{2-17 4.} FIG. 11 is a flowchart of a first modification of the setting process executed by the control circuit 37 of each of the weighing machines 17 _{1 to} 17 ₄ .

As shown in FIG. 11, each weighing machine 17 ₁
To 17 ₄ of control circuit 37, in S41, the setting mode signal from the remote controller 32 checks whether the inputted. In S41, when the setting mode signal is input from the remote controller 32, the process proceeds to S42, in which a three-digit random number Z (Z = 951) is generated and stored, for example. In the present embodiment, four weighing machines 17 ₁ to 17 ₁
7 ₄ to order to generate a 3-digit random numbers, each weighing machine 17 ₁
Possibility probability of displaying the same random number to 17 ₄ to display the same number as low Ku other of the weighing machine 17 is small.

In the next step S43, the random number Z (Z = 951) is displayed on the display device 40 of the weighing machine 17 as an identification symbol. Subsequently, in S44, the remote controller 32
Check whether a numerical signal has been input from. That is, the staff at the gas station inputs the numerical value (951) displayed on the display device (display means) 40 of the weighing machine 17 with the remote controller 32 and transmits it.

At S45, it is checked whether or not the numerical value transmitted from the remote controller 32 is the same as the random number Z displayed on the display device 40. In S45, when the numerical value transmitted from the remote controller 32 is the same as the random number Z displayed on the display device 40,
Proceeding to 46, the mode shifts to the setting mode (setting means) to notify this.

If the value transmitted from the remote controller 32 is not the same as the random number Z displayed on the display device 40 in S45, the process proceeds to S47, where the storage of the random number Z is deleted, and the process returns to S41. After the setting mode transition is notified in S46, various setting processes are performed in S48.
The setting process performed in S48 includes, for example, nozzle number and oil type, or refueling permission and refueling stop.

In S49, it is checked whether the setting process has been completed. Until the setting process is completed, S
48 and S49 are repeated. In S49,
When the setting process ends, the current process ends. Thus, in order to transmit the random number Z which is displayed on the display device 40 of the weighing machine 17 from a remote controller 32, it is placed in a position in which a plurality of weighing devices 17 ₁ to 17 ₄ are close to each fueling nozzle 27 nozzle setting process only in the weighing machine 17 ₁ is removed from over 29 is performed, it is not performed setting processing even signal is received from the other of the weighing machine 17 _{2-17 4} remote controller 32. Therefore, in the plurality of weighing machines 17 _{1 to} 17 ₄ , the setting signal by the remote controller 32 is incorrectly set to the adjacent weighing machine 1.
7 can be prevented from being received as an individual setting change value.

It is needless to say that, instead of displaying the random number Z on the display device 40, a numerical value other than the random number Z, a symbol, an alphabet or the like can be displayed. Further, in the above description, the case where the refueling permission or the refueling stop is set by the remote controller 32 has been described.
2 can of course be set.

Further, in the above-described embodiment, the above-mentioned ground-type oil supply device has been described as an example. However, the present invention is not limited to this, and it is needless to say that the present invention can also be applied to a suspension-type oil supply device that raises and lowers an oil supply nozzle.

[0063]

As described above, according to the first aspect of the present invention, the information received by the receiving unit when the removal of the refueling nozzle from the nozzle hook is detected is set in the control unit. The information received by the receiver can be set only for the refueling device whose refueling nozzle has been removed from the nozzle hook,
It is not set even if the same information is received by another fueling device adjacent to the surroundings. Therefore, even if the information transmitted from the external transmitter is received simultaneously by a plurality of refueling devices, the information can be set only by the refueling device.

According to the second aspect of the present invention,
The weighing machine is provided with a display means for displaying an identification symbol unique to the weighing machine, and the information received by the reception unit when the identification symbol displayed on the display unit is input to the reception unit is transmitted to the control unit of the fueling device. For setting, even if the same information is received by another refueling device adjacent to the surroundings, the setting is not performed because the identification symbol is different. Therefore, even if the information transmitted from the external transmitter is received simultaneously by a plurality of refueling devices, the information can be set only by the refueling device.
