Description

The present disclosure relates to a fuel supply system applied to a self-service fuel supply facility in which the customer himself / herself performs the fuel supply work.

At self-service fuel supply facilities, such as self-service gas stations, customers themselves monitor the refueling work for vehicles and other refueling targets by the staff of the refueling station (gas station manager, etc.). To do this.

In a fuel supply system applied to such a self-service fuel supply facility, the customer measures the actual fuel supply (refueling) to the supply target (refueling target) as in the refueling system described in Patent Document 1. Before starting by operating the nozzle (refueling nozzle) of the machine (refueling device), operate the setting device in advance to supply work information (refueling work conditions) to the weighing machine used in the fuel supply work (refueling work). Is set, and the person in charge obtains permission to carry out the fuel supply work determined based on the supply work information.

As for supply work information, in the refueling system described in Patent Document 1, oil types such as regular / high-octane / light oil (supply liquid type), oil amount such as fixed amount / fixed amount / full tank (supply liquid amount), ordinary vehicles / light vehicles Refueling target vehicle type (supply target type) such as / bike / truck etc. is applicable.

On the other hand, the staff member supplies the measuring machine set by the customer to the weighing machine used in the fuel supply work on the monitoring screen of the management machine (refueling management machine) provided in the office (stand office) in the fuel supply facility. Check work information remotely and centrally for each weighing machine. Then, if no error or abnormality is confirmed in the setting contents of the supply work information set by the customer, the staff member permits the execution of the fuel supply work by the corresponding measuring machine on the monitoring screen.

As a result, the operation permission (drive permission command) based on the permission operation of the staff is supplied to the relevant weighing machine from the management machine. In the corresponding weighing machine that has received this operation permission, the liquid feeding means is driven by operating the nozzle, and fuel can be supplied to the supply target. Then, when the nozzle of the measuring machine is opened, fuel is discharged from the nozzle, and the actual fuel supply to the supply target using the measuring machine is started.

Japanese Unexamined Patent Publication No. 2010-58793

In the conventional self-service fuel supply system, when the management machine side operates the permission to carry out the fuel supply work by the corresponding measuring machine and the operation permission from the management machine is input to the corresponding measuring machine, the customer receives the message. Even if the staff is not present at the site, that is, the fuel supply work area of the weighing machine, by operating the nozzle of the weighing machine by itself, the weighing machine can operate the fuel supply and start the actual fuel supply to the supply target. ..

However, even in a self-service fuel supply facility, depending on the type of fuel supply work using the weighing machine, a staff member may operate the nozzle of the weighing machine on behalf of the customer for reasons such as work safety. It may be necessary to carry out fuel supply work.

Here, in the self-service fuel supply system described above, for example, although the fuel supply work to be performed is the type of vehicle to be refueled (type to be supplied) corresponding to the fuel supply work to be performed by the staff. , If the staff does not notice at the time of setting, setting operation of useless supply work information such as oil type (supply liquid type) such as regular / high octane / light oil and refueling amount (supply liquid amount) such as fixed amount / fixed amount / full tank Will be done by the customer with the setting device.

Also, for the staff, when performing the fuel supply work on behalf of the customer, it is necessary to cancel the extra supply work information that has been set by the customer so far, and for that reason, the staff in charge of the fuel supply work There is a problem that efficiency is also deteriorated.

Specific cases such as this include cases where the customer himself / herself is prohibited from supplying fuel in advance, and when fuel is supplied to a tank other than a vehicle such as a fuel carrying can (fuel carrying tank). Applicable.

In addition, when deciding whether or not to permit the implementation of self-service fuel supply work, the staff will operate the fuel supply of the relevant weighing machine only from the setting contents of the supply work information on the monitoring screen of the management machine. If it is not possible to determine the pros and cons, it is necessary to go to the site, that is, the fuel supply work area of the relevant weighing machine to make additional confirmation. At that time, when going to the site, if the management machine first permits the fuel supply operation of the relevant weighing machine, the customer himself operates the nozzle to supply the target before the additional confirmation is made. In some cases, the actual fuel supply may be started. As a result, an inappropriate situation such as supplying fuel of the wrong liquid type to the supply target may occur.

In view of the above-mentioned problems, the present disclosure is applied to a self-service fuel supply facility, and is related to a self-service fuel supply work performed by the customer himself / herself by operating the nozzle of the weighing machine, and the work of each customer and staff. The purpose is to provide a fuel supply system with improved efficiency.

The fuel supply system of the present disclosure is applied to a self-service fuel supply facility, and the fuel supply work based on the set supply work information does not require the fuel supply work by the staff, and the self-service fuel supply work by the customer. It is determined whether the fuel supply work is a non-self-service type fuel supply work that requires fuel supply work by a staff member, and if it is determined that the fuel supply work is a non-self-service type fuel supply work, the weighing machine is notified. , It is configured to prohibit fuel supply to the nozzle.

Specifically, the fuel supply system of the present disclosure is set by operating a setting device for setting supply work information related to the fuel supply work in advance and a nozzle provided at the tip of the hose when performing the fuel supply work. There is no need for a staff member to supply fuel based on the metering machine that supplies fuel to the supply target based on the supply work information set by the device and the supply work information related to the fuel supply work set by the set device. A work discriminating unit that determines whether the fuel supply work is a self-service type by the customer or a non-self-service type fuel supply work that requires a fuel supply work by a staff member, and a non-self-service by the work discriminating unit. When it is determined that the fuel supply work is of the type, it is provided with a supply control unit that prohibits the weighing machine from sending fuel to the nozzle.

According to the fuel supply system of the present disclosure, if it is determined that the fuel supply work based on the set supply work information is a non-self-service fuel supply work that requires the fuel supply work by the staff, the weighing machine On the other hand, since the fuel supply to the nozzle is prohibited, it is possible to improve the work efficiency of each customer and the staff in the self-service fuel supply system.

Further, if unset supply work information related to the fuel supply work remains, the setting device is prevented from setting the unset supply work information, and the weighing machine is directed to the nozzle. By prohibiting fuel supply, it is possible to further improve the work efficiency of each customer and staff.

In addition, issues, configurations, and effects other than those described above in the present disclosure will be clarified by the following description of the embodiments.

An embodiment of the fuel supply system according to the present disclosure will be described with reference to the drawings, exemplifying a case where it is applied to a refueling system of a self-service gas station.

FIG. 1 is a schematic overall configuration diagram of a refueling system to which the fuel supply system according to the present disclosure is applied.

The specific configuration of the refueling system of the self-service gas station shown in FIG. 1 is only one embodiment, and is not limited to the configuration shown in the figure.

In FIG. 1, the refueling system (fuel supply system) 1 is roughly composed of a weighing machine 10, a refueling terminal (setting device) 20, and a refueling management machine (management machine) 40. The weighing machine 10, the refueling terminal 20, and the refueling management machine 40 are connected to a LAN (Local Area Network) in the self-gas station, and control signals and information data can be transmitted and received between these devices.

In the illustrated example, the number of the weighing machine 10, the refueling terminal 20, and the refueling management machine 40 is one (one) for facilitating the technical understanding of the refueling system 1 according to the present embodiment. Although shown by each, it is not limited to this. For example, since the weighing machine 10 is usually installed corresponding to the refueling work area (fuel supply work area) 2, the number of the weighing machine 10 is the number of the refueling work area (fuel supply work area) 2 in the self-gas station. It changes accordingly. Similarly, the number of refueling terminals 20 also changes according to the number of refueling work areas 2 and the number of weighing machines 10.

The weighing machine 10 refuels the refueling target (supply target) 3 of the vehicle or the like in the corresponding refueling work area 2 on condition that the refueling management machine 40 supplies the permission to carry out the refueling work (fuel supply work). I do.

In the illustrated example, the weighing machine 10 includes a plurality of refueling systems (fuel supply systems) 11 having different oil types, such as gasoline, high-octane gasoline, and light oil, and the desired oil for the refueling target 3 in the refueling work area 2. The structure is such that the seed (supply liquid type) can be refueled. Therefore, each refueling system 11 of the weighing machine 10 is communicatively connected to the oil storage tank 19 of the corresponding oil type (gasoline, high-octane gasoline, or light oil in the illustrated example).

Each refueling system 11 is provided with a nozzle 12 at the tip, and has a hose 13 led out from the measuring machine main body and a liquid feeding device such as a pump and a flow rate housed in the measuring machine main body and communicated with the base end of the hose 13. It has a measuring device such as a meter (not shown).

Each nozzle 12 has a built-in nozzle valve that opens and closes in response to a lever operation, and is housed in each nozzle storage portion 14 of the main body of the weighing machine during standby when it is not used in refueling work. During the refueling operation, the nozzle 12 is taken out from the nozzle storage unit 14 by a customer or a staff member who is an operator and used. Each nozzle storage unit 14 is provided with a nozzle detector (not shown) that detects the start / end of execution of the actual refueling work by hooking / removing the nozzle 12.

The pump of the liquid feeding device (not shown) pumps the oil liquid from the oil storage tank 19 of the corresponding oil type and sends it to the nozzle 12 of the corresponding refueling system 11 via the flow meter (not shown) of the measuring device. Liquid. The flow meter measures the amount of oil liquid supplied to the nozzle 12, that is, the amount of oil supplied from the nozzle 12 to the object 3 to be refueled (the amount of liquid supplied). The flow meter is equipped with a flow pulse transmitter (not shown) that outputs a flow pulse according to the flow of each unit flow rate.

Further, in the main body of the measuring machine, in addition to the liquid feeding device and the measuring device of each of the refueling system 11, a measuring machine control device 16 for operating and controlling each part of the measuring machine is provided. The weighing machine control device 16 is composed of a computer device having a communication function, including a CPU, RAM, ROM, and an interface.

In the case of the illustrated weighing machine 10, the measuring machine control device 16 executes and controls the refueling operation by the corresponding refueling system 11 selectively selected from the plurality of refueling systems 11 having different oil types.

The weighing machine control device 16 has a refueling work permit (fuel supply permit) from the refueling management machine 40 for the refueling system 11 corresponding to the oil type specified in the refueling work information (fuel supply work conditions) set in advance at the time of refueling work. , The operation of the liquid feeding device is controlled under the conditions of nozzle hooking / removing detection from the nozzle detector, staff location detection from the staff detector 60 described later, and the like, and liquid feeding control to the nozzle 12 is performed. Then, when the actual refueling using the nozzle 12 of the corresponding refueling system 11 is started, the refueling control corresponding to the amount of oil specified in the refueling work information is performed by operating and controlling the liquid feeding device, and the corresponding refueling is performed. Based on the flow rate pulse output from the flow rate pulse transmitter of the system 11, the refueling data such as the amount of refueling for the refueling target is calculated, and the display is controlled on the display 18 provided in the main body of the measuring machine. Further, the weighing machine control device 16 refuels the weighing machine status information based on the execution start / execution end of the refueling work by the corresponding refueling system 11, and the refueling data such as the refueling amount in the refueling work of the corresponding refueling system 11. It is appropriately output to the terminal 20, the refueling management machine 40, the point-of-sale information management machine (POS) (not shown), and the like.

The refueling terminal 20 will be performed by the customer in a self-service refueling operation in which the customer himself operates the nozzle 12 of the weighing machine 10 to refuel a desired amount of oil of a desired oil type to the refueling target 3. Set and enter the refueling work information related to the self-service refueling work.

Like the weighing machine 10, the refueling terminal 20 is provided corresponding to the refueling work area 2 in the self-gas station. In the illustrated example, it is provided integrally with the main body of the weighing machine, but it may be provided separately from the weighing machine 10, or it may be provided corresponding to a plurality of measuring machines 10 and a plurality of measuring machines. It is also possible to share the refueling terminal 20 with 10.

FIG. 2 is an enlarged view of a refueling terminal integrally provided on the main body of the weighing machine in the refueling system shown in FIG.

In the illustrated example, the refueling terminal 20 includes a setting device unit 21, a refueling guide unit 26, and a slip issuing unit 29, and further, a staff detector 60 and a cap placing unit 35 are integrally provided. It has become.

The setting device unit 21 is an operation input unit for setting and inputting refueling work information of the refueling work that the customer is about to start executing when performing the refueling work using the measuring machine 10. In the illustrated example, the setting device unit 21 is provided with a refueling target selection unit 22 and a refueling work setting unit 23.

The refueling target selection unit 22 is an operation input unit for selecting and setting the type of refueling target in the self-service refueling work to be performed.

In the illustrated example, the refueling target selection unit 22 has a configuration in which a "carrying can / plastic tank" can be newly selected in addition to the "light vehicle", "ordinary vehicle", and "motorcycle". As a result, any one of "light vehicle", "ordinary vehicle", "motorcycle", or "carrying can / plastic tank" can be selected and set as a refueling target in the refueling work to be performed. The refueling target selection unit 22 is designed to identify and display the refueling target that has been selected.

The refueling work setting unit 23 is an operation input unit for selecting and setting refueling conditions in the self-service refueling work to be performed. In the illustrated example, the refueling work setting unit 23 is further divided into an oil type setting unit 24 and a refueling amount setting unit 25.

The oil type setting unit 24 can select and set any one of "high octane", "regular", and "light oil" as the refueling oil type in the refueling work to be performed. The oil type setting unit 24 is designed to identify and display the refueling oil type that has been selected and operated.

The refueling amount setting unit 25 has a fixed amount such as 10 [L], 20 [L], 30 [L], 40 [L], a fixed amount such as 1000 [yen], 2000 [yen], 3000 [yen], and 4000 [yen]. , Or one of "full tank" can be selected and set as the amount of refueling oil in the refueling work to be performed. The refueling amount setting unit 25 is designed to identify and display the refueling amount that has been selected and operated.

The refueling target selected and set by the refueling target selection unit 22, the refueling oil type set by the oil type setting unit 24 of the refueling work setting unit 23, and the refueling amount set by the refueling amount setting unit 25 are all. Refueling work information indicating the refueling work conditions of the refueling work that the customer is about to perform using the measuring machine 10 is supplied from the refueling terminal 20 to the measuring machine control device 16 of the measuring machine 10 and the refueling management machine 40. To.

The refueling guide unit 26 outputs a guidance voice and a notification voice as voice operation guides for the refueling terminal 20 and the weighing machine 10 in accordance with the progress of the self-service refueling work by the customer.

Further, in the illustrated example, the refueling guide unit 26 is provided with an intercom slave unit function so that it can also function as a staff calling unit 27. The customer operates the call operation unit 28 of the staff call unit 27, and the staff of the gas station (for example, the gas station manager) waiting in the office via the intercom master unit provided in the stand office. Etc.), and can receive instruction and instructions on refueling work.

After the execution of the refueling work is completed, the slip issuing unit 29 prints out a settlement slip in which the slip number, the amount of refueling, the refueling price, etc. are described based on the refueling data calculated by the weighing machine control device 16.

In the illustrated example, the customer reads the settlement slip issued by the slip issuing unit 29 by a settlement machine (not shown) separately provided in the self-service gas station by being connected to the point-of-sale information management machine for communication and settlement. The refueling fee is settled after payment depending on the machine.

In the case of the refueling terminal 20 which is further provided with the payment / change device unit together with the slip issuing unit 29, the slip issuing unit 29 issues a settlement slip instead of a receipt after the refueling work using the weighing machine 10 is completed. Print out. In this case, it is not necessary to settle the refueling fee after payment by the settlement machine, and the refueling fee can be paid and the change can be settled in the refueling work area 2.

The staff detector 60 detects whether or not a staff at a gas station is located in the refueling work area 2 corresponding to the measuring machine 10. In the illustrated example, the clerk detector 60 includes a lock mechanism 61, a lock state detector 62, and a portable key 63.

The lock mechanism 61 is unlocked when a mobile key 63 carried by a staff member is attached, and is automatically locked when the lock mechanism 61 is taken out. The lock state detector 62 is attached to the lock mechanism 61, detects the attached / unattached state of the portable key 63 to the lock mechanism 61, that is, the unlocked / locked state of the lock mechanism 61, and outputs a staff location detection signal. The output is output to the weighing machine control device 16 of the weighing machine 10.

In the illustrated example, the clerk detector 60 is refueled because the refueling terminal 20 is integrally provided in the weighing machine main body corresponding to 1: 1 with the weighing machine 10 and the refueling work area 2. The terminal 20, that is, the weighing machine 10, is integrally provided. The clerk detector 60 may be provided so as to correspond to the refueling work area 2 or the weighing machine 10 in a ratio of 1: 1 and may be provided separately from the refueling terminal 20 and the measuring machine 10. Good.

The refueling port cap removed from the refueling target is temporarily held and stored in the cap holder 35 during the refueling operation. Even if the cap holder 35 is not integrally provided in the refueling terminal 20, it corresponds to the refueling work area 2 or corresponds to each refueling system 11 (every nozzle 12) of the weighing machine 10 in the refueling work area 2. It is also possible to provide a configuration.

Returning to FIG. 1 again, the refueling management machine 40 is installed in the stand office where the staff is waiting.

The refueling management machine 40 is composed of a computer device having a communication function. In the illustrated example, the refueling management machine 40 is communicatively connected to the weighing machine control device 16 and the refueling terminal 20 of the measuring machine 10 for each refueling area 2, and a control signal is transmitted between the measuring machine 10 and the refueling terminal 20. And information data can be sent and received.

The refueling management machine 40 is based on the transmission and reception of control signals and information data between the refueling area 2 and the weighing machine 10 on the user interface screen, and the operating status and weighing of each measuring machine 10 in the self-gas station. The refueling work status of each machine 10 is displayed graphically.

On the user interface screen of the refueling management machine 40 configured in this way, the staff can remotely and centrally monitor and check the operating status and refueling work status of each weighing machine. There is.

Among the operating status and refueling work status of each measuring machine, the operating / stopped (power ON / OFF) state of the measuring machine 10, the refueling work in progress / standby state of the measuring machine 10 in the operating (power ON) state, The refueling work information set by the refueling terminal 20 for the measuring machine 10 in the operating (power ON) state, the actual refueling amount for the refueling target 3, and the like are included.

Then, the refueling management machine 40 is in a state of waiting for refueling work permission from the user interface screen, in which the operation / stop (power ON / OFF) of each weighing machine 10 and the refueling work information are set by the refueling terminal 20. Various weighing machine operations such as permission for refueling work for the machine 10 and emergency stop for refueling work for the measuring machine 10 in the state of being refueled can be performed.

In addition, in the illustrated example, the refueling management machine 40 is provided with a portable portable management machine terminal 41 that is wirelessly connected to the refueling management machine 40. The mobile management device terminal 41 is provided with a user interface screen similar to that of the refueling management machine 40.

With this mobile management machine terminal 41, if the person in charge carries the mobile management machine terminal 41 and stays in the self-service gas station even if he / she is not in the stand office, each measurement is performed on the user interface of the mobile management machine terminal 41. The status of the machine 10 and various weighing machine operations can be performed via the refueling management machine 40 connected by wireless communication.

On top of that, in the refueling system 1 of the present embodiment configured as described above, the compulsory setting table 50 for the non-self-service refueling work is stored in the weighing machine control device 16 of the weighing machine 10. In this case, the non-self-service refueling work (fuel supply work) is the opposite of the self-service refueling work, and is a refueling work that needs to be performed by a staff member.

In the self-service refueling work, even if the staff is not in the refueling work area 2, the staff confirms the status of the weighing machine 10 and the set refueling work information with the refueling management machine 40 and refuels the measuring machine 1. By permitting, the customer himself / herself can operate the nozzle of the weighing machine 10 to perform the refueling work to the refueling target 3.

In this embodiment, if the fuel supply operation of the corresponding measuring machine 10 for which the customer has set the refueling work information by the refueling terminal 20 is permitted on the side of the refueling management machine 40 by the staff, the customer will be asked by the staff. Even if you are not present in the refueling work area 2, the corresponding measuring machine 10 operates to supply fuel by operating the nozzle 12 of the corresponding measuring machine 10 by itself, and the actual refueling (fuel) to the refueling target is performed. Supply) can be started.

On the other hand, in the non-self-service refueling work, even if the staff permits the fuel supply operation of the corresponding weighing machine 10 for which the customer has set the refueling work information by the refueling terminal 20 on the refueling management machine 40 side. If the person in charge is not in the fuel supply work area 2 of the measuring machine 10, the measuring machine 10 does not operate the fuel supply, and even if the customer operates the fuel supply of the nozzle 12 of the measuring machine 10, the actual fuel supply target is actually supplied. It refers to the refueling work that cannot start refueling.

In the non-full service type refueling work, the staff operates the nozzle 12 of the weighing machine 10 on behalf of the customer to perform the refueling work to the refueling target, thereby performing the refueling work to the refueling target 3.

Such non-self-service refueling work also includes a full-service refueling work in which a staff member performs refueling work on the refueling target on behalf of the customer.

FIG. 3 is a schematic diagram showing an embodiment of a compulsory setting table for non-self-service (full-service) refueling work.

In the illustrated example, the non-self-service refueling work compulsory setting table 50 stores three compulsory setting patterns Nos. 1 to 3 as compulsory setting patterns.

In the No. 1 compulsory setting pattern, when the "carrying can / plastic tank" of the transport container is selected and set as the refueling target by the refueling target selection unit 22 of the refueling terminal 20, the refueling work is a self-service refueling work. Instead, non-self-service refueling work is compulsorily set.

In the No. 2 compulsory setting pattern, the refueling target selection unit 22 of the refueling terminal 20 selects and sets "light vehicle" as the set refueling target, and the refueling work setting unit 23 selects and sets "light oil" as the set oil type. Then, the refueling work is forced to be a non-self-service refueling work.

In the forced setting pattern of No. 3, "motorcycle" is selected and set as the set refueling target in the refueling target selection unit 22 of the refueling terminal 20, and "40L" is selected and set as the set refueling amount in the refueling work setting unit 23. Then, the refueling work is forced to be a non-self-service refueling work.

In the illustrated example, the No. 1 compulsory setting pattern prohibits the refueling work by the customer who targets the carrying can / plastic tank, and only the staff members perform the refueling work to the transport container including the carrying can / plastic tank. It is for letting you.

Further, the compulsory setting patterns of No. 2 and No. 3 correspond to a predetermined combination of the refueling work information set by the customer, in which the refueling target, the set oil type, and the set refueling amount are preset. In this case, the customer's self-service refueling work for the refueling target is temporarily prohibited.

Then, for the customer who sets such refueling work information, even if the person in charge grants the refueling work permission by the corresponding measuring machine 10 after the setting error is corrected, the fuel supply work of the corresponding measuring machine 10 is performed. Even if the customer operates the nozzle 12, the actual refueling (fuel supply) to the refueling target is not started until the staff actually visits the area 2 and confirms that there is no error. In this way, for refueling work in which the setting error of the refueling work information is suspected, it is preferable to temporarily set it to non-self-service refueling work by the staff from the viewpoint of safety in the refueling work, and the customer can refuel by self-service method. Even if you try to do the work, non-self-service refueling work is forcibly set.

The stored contents of the compulsory setting table 50 are self-service together with the refueling target selection item by the refueling target selection unit 22 in the setting device unit 21, the oil type selection item by the refueling work setting unit 23, and the refueling amount / refueling amount selection item. It is possible to change it according to the refueling work situation of each stand.

For example, the change may be made by the manufacturer at the time of system manufacturing, system maintenance, etc., or transmission / reception of control signals and information data to / from the weighing machine control device 16 of the weighing machine 10. The refueling management machine 40, which is capable of the above, can be used by a staff member of a gas station, which is a user, at will, and may be downloaded from the refueling management machine 40.

Next, the flow of the self-service refueling work by the refueling system 1 of this embodiment will be described with reference to the flowcharts shown in FIGS. 4 to 7.

FIGS. 4 to 7 are flowcharts showing an embodiment of the control process in the self-service refueling operation by the refueling system of the present embodiment.

First, the customer who visits the store parks the vehicle in the refueling work area 2, operates the nozzle 12, and before starting the actual refueling to the refueling target 3, the refueling work information is previously provided by the setting device 21 of the refueling terminal 20. By setting, self-service refueling work is started.

In the case of the refueling terminal 20 shown in FIGS. 1 and 2, the customer sets the refueling work information of the self-service refueling work to be performed, and (1) selects the refueling target 3 by the refueling target selection unit 22. Setting, (2) Oil type selection setting by the oil type setting unit 24 of the refueling work setting unit 23, (3) Selection setting of the refueling amount by the refueling amount setting unit 25, in that order, the setting device unit of the refueling terminal 20 21 is operated and set. The set refueling target, the set oil type, and the set refueling amount set by the customer in this way are the refueling work information of the self-service refueling work, respectively, from the refueling terminal 20 to the weighing machine control device 16 of the weighing machine 10. And is supplied to the refueling management machine 40.

In this embodiment, as shown in FIG. 4, the weighing machine control device 16 of the measuring machine 10 in the operating state (device power is on) inputs the refueling work information from the setting device unit 21 of the refueling terminal 20. By monitoring the presence or absence of the above, it is monitored whether or not the self-service refueling work using the weighing machine 10 has been started by the customer (step S010).

Then, when the weighing machine control device 16 detects the input of the set refueling target based on the operation of the refueling target selection unit 22 in the setting device unit 21 from the refueling terminal 20 (S010), the customer applies the set refueling target. It is temporarily stored as refueling work information to be performed by using the measuring machine 10 and is also supplied to the refueling management machine 40.

On that basis, the weighing machine control device 16 serves as a work discriminating unit, and the refueling work for the set refueling target that the customer intends to perform using the measuring machine 10 is either a self-service refueling work or a non-self. It is confirmed by referring to the compulsory setting table 50 whether or not the service type refueling work is performed (S020).

As a result, in the weighing machine control device 16, for example, when the customer selects and sets the "carrying can / plastic tank" as the refueling target 3, the customer is about to perform the compulsory setting table 50 shown in FIG. Since the refueling work corresponds to the compulsory setting pattern No. 1 of the non-self-service refueling work (S030), the refueling work that the customer is about to perform is set to the non-self-service refueling work (S040). ..

Further, the weighing machine control device 16 sends a refueling work request (calling request of the staff) to the refueling work area 2 to the refueling management machine 40 (S050), and also sends a refueling work request (calling request of the staff) to the refueling terminal 20. , The operation lock of the setting device unit 21 is transmitted, and the setting device unit 21 of the refueling terminal 20 is put into the operation lock state in which the customer's operation cannot be accepted (S060). As a result, the customer can use the refueling terminal 20 to perform "(2) oil type selection setting by the oil type setting unit 24 of the refueling work setting unit 23" and "(3) oil type selection setting by the refueling amount setting unit 25". Is no longer possible, and the setting of refueling work information related to the refueling work that the customer is about to perform will be interrupted at the stage when "(1) Selection setting of refueling target 3 by the refueling target selection unit 22" is performed. become.

Further, along with the interruption of the setting of the refueling work information, the weighing machine control device 16 independently prohibits the fuel supply to the nozzle 12 regardless of whether or not the refueling work permission is supplied from the refueling management machine 40.

Accordingly, even if the operation of the embodiment permits refueling operations by the clerk is made in the oil supply management device 40 side, the clerk does not need the revocation process performed authorization of the refueling operations performed by the fueling tiller 40 side , It is possible to improve the workability of the staff in the self-service fuel supply system.

Further, even if the customer operates the nozzle 12, the customer may operate the nozzle 12 until the staff member goes to the fuel supply work area 2 of the measuring machine 10 and additionally confirms whether or not the set refueling work information is incorrect. Since the actual fuel supply to the supply target is not started, it is possible to surely prevent the customer from starting the actual refueling before the additional confirmation by the staff, and the safety of the fuel supply work is further improved.

Along with the setting for such non-self-service refueling work, the weighing machine control device 16 states that "the progress of the refueling work by the weighing machine 10 is interrupted until the staff arrives at the refueling work area 2." The refueling guide unit 26 is operated to notify the customer of the guidance (S062).

Then, the weighing machine control device 16 monitors whether or not the staff member has arrived at the refueling work area 2 by monitoring the presence or absence of the input of the staff member location detection signal from the staff member detector 60 (S064).

On the other hand, in the refueling management machine 40 that has received the refueling work request (calling request of the staff) by the staff, that is, the setting of the non-self-service refueling work by the staff, which is transmitted from the weighing machine control device 16, the weighing source is measured. At the machine 10, the refueling management machine 40 itself and the portable management machine terminal 41 visually and / or audibly notify the staff that a request for non-self-service refueling work has occurred, and alert the staff. To do.

As a result, the clerk can grasp the occurrence of a non-self-service refueling work request by the clerk even if he / she is away from the stand office or the measuring machine 10 of the originator in the stand premises. You can head to the refueling work area 2 of the source weighing machine 10.

After that, when the clerk arrives at the measuring machine 10 of the transmission source and the refueling work area 2 thereof, the clerk puts the portable key 63 carried by the clerk in the lock mechanism 61 of the clerk detector 60 provided in the measuring machine main body. It is attached to unlock the lock mechanism 61. The lock state detector 62 of the clerk detector 60 detects the unlocked state of the lock mechanism 61 and sends a clerk location detection signal to the measuring machine control device 16 of the measuring machine 10. In this embodiment, while the lock mechanism 61 is unlocked by attaching the mobile key 63, the lock state detector 62 supplies the staff location detection signal to the weighing machine control device 16 of the measuring machine 10. It has become.

When the clerk arrives at the refueling work area 2 and is located in the refueling work area 2, the measuring machine control device 16 determines it based on the input of the clerk location detection signal from the clerk detector 60. (S064).

As a result, when the weighing machine control device 16 determines that the staff member is located in the refueling work area 2, it transmits the refueling terminal 20 to release the operation lock of the setting device unit 21. As a result, "(2) Oil type selection setting by the oil type setting unit 24 of the refueling work setting unit 23" and "(3) Refueling amount by the refueling amount setting unit 25" in the refueling terminal 20 that have been interrupted The "selection setting" can be performed (S066).

That is, in this case, in the compulsory setting table 50 shown in FIG. 3, when the customer selects and sets the “carrying can / plastic tank” as the refueling target 3, the refueling work that the customer is about to perform is non-self-service. Since it corresponds to the compulsory setting pattern No. 1 of the refueling work of the method, the staff can proceed with the subsequent refueling work for the refueling target 3 by the non-self-service refueling work by the staff.

On the other hand, in step S010 described above, when the customer inputs any of "light vehicle", "ordinary vehicle", or "motorcycle" other than "carrying can / plastic tank" from the refueling terminal 20 as the set refueling target. The weighing machine control device 16 temporarily stores the set refueling target as refueling work information that the customer is about to perform using the weighing machine 10, and also supplies the refueling management machine 40.

Then, the weighing machine control device 16 confirms, as a work discriminating unit, whether or not the refueling work for the set refueling target is a non-self-service refueling work by referring to the compulsory setting table 50 (see the compulsory setting table 50). S020).

However, in this case, even if the weighing machine control device 16 refers to the compulsory setting table 50, the customer can simply set either the "light vehicle", the "ordinary vehicle", or the "motorcycle" as the refueling target. At present, it is confidently determined whether or not the refueling work to be performed using the measuring machine 10 corresponds to the No. 2 or No. 3 compulsory setting pattern related to the non-self-service refueling work. Cannot be done (S030).

Therefore, in this embodiment, in such a case, the weighing machine control device 16 temporarily sets the refueling work that the customer is about to perform to the self-service refueling work (S070). After that, the weighing machine control device 16 continues to perform the refueling terminal 20 without performing the process shown in steps S050 to 066, and continues to "(2) Select the oil type by the oil type setting unit 24 of the refueling work setting unit 23". Make it ready for "setting".

FIG. 5 shows the oil type of the refueling terminal 20 by the oil type setting unit 24 of the refueling work setting unit 23, which is performed following "(1) Selection setting of the refueling target 3 by the refueling target selection unit 22". The control process of the weighing machine control device 16 as the work discriminating unit at the time of "selection setting of" is shown.

Further, FIG. 6 shows, in the refueling terminal 20, "(1) selection setting of refueling target 3 by refueling target selection unit 22" and "(2) selection of oil type by oil type setting unit 24 of refueling work setting unit 23". It shows the control process of the measuring machine control device 16 as a work discriminating unit at the time of "(3) selection setting of the refueling amount by the refueling amount setting unit 25" performed after "setting".

In addition, in FIGS. 5 and 6, the description of the processing content similar to the processing content at the time of "(1) Selection setting of the refueling target 3 by the refueling target selection unit 22" in the refueling terminal 20 shown in FIG. Is the last two-digit number ●● of the number indicated by step S ○ ●● in FIGS. 5 and 6, and the last two-digit number ▲▲ of the number indicated by step S △▲▲ in FIG. The numbers will be the same, and the explanation will be simplified or omitted.

At the time of "(2) oil type selection setting by the oil type setting unit 24 of the oil supply work setting unit 23" performed following "(1) selection setting of the oil type 3 by the oil supply target selection unit 22", the weighing machine control device. 16 performs a process as shown in FIG. 5 as a work determination unit.

That is, in steps S120 and 130, the weighing machine control device 16 determines whether or not the refueling work of the set oil type for the set refueling target to be performed is a non-self-service refueling work, the compulsory setting table 50. Check by referring to.

Therefore, in steps S120 and 130, for example, in the table contents of the compulsory setting table 50 shown in FIG. 3, the refueling work that the customer is about to perform is the compulsory setting pattern No. 1 of the above-mentioned non-self-service refueling work. In addition, the weighing machine control device 16 determines whether or not the compulsory setting pattern No. 2 for the non-self-service refueling work is applicable.

In the example of the compulsory setting table 50 shown in FIG. 3, the compulsory setting pattern No. 2 of the non-self-service refueling work is composed of an AND condition between a predetermined set refueling target and a predetermined set oil type. If a compulsory setting pattern for non-self-service refueling work consisting of only a predetermined set oil type is set in the compulsory setting table 50, such a compulsory setting pattern can also be determined in steps S120 and 130.

Therefore, by the process shown in FIG. 5, it was determined in steps S120 and 130 that the refueling work that the customer is about to perform corresponds to the compulsory setting pattern No. 1 or No. 2 of the non-self-service refueling work. In this case, non-self-service refueling work is set, and if the staff is not in the refueling work area 2, "(3) Refueling amount selection setting by the refueling amount setting unit 25" cannot be performed (S140 to 166). ..

On the other hand, in steps S120 and 130, when it is determined that the refueling work that the customer is about to perform does not correspond to the compulsory setting patterns No. 1 and No. 2 of the non-self-service refueling work. The self-service refueling operation set in step S070 of FIG. 4 is maintained, and the weighing machine control device 16 continues to "refuel the refueling terminal 20" without performing the processing shown in steps S150 to 166. (3) Make the state in which the "selection setting of the refueling amount by the refueling amount setting unit 25" can be performed.

Following "(1) Selection setting of refueling target 3 by refueling target selection unit 22" and "(2) Selection setting of oil type by oil type setting unit 24 of refueling work setting unit 23", "(3) Refueling" At the time of "selection setting of the amount of refueling by the amount setting unit 25", the measuring machine control device 16 performs the process as shown in FIG. 6 as the work determination unit.

That is, in steps S220 and 230, the weighing machine control device 16 determines whether or not the refueling work of the set oil type and the set refueling amount for the set refueling target to be performed is a non-self-service refueling work. Check by referring to the compulsory setting table 50.

Therefore, in steps S220 and 230, for example, in the table contents of the compulsory setting table 50 shown in FIG. 3, the refueling work that the customer is about to perform is the compulsory setting pattern No. 1 of the above-mentioned non-self-service refueling work. In addition to No. 2, the weighing machine control device 16 also determines whether or not the compulsory setting pattern No. 3 for non-self-service refueling work is applicable.

In the example of the compulsory setting table 50 shown in FIG. 3, the compulsory setting pattern No. 3 of the non-self-service refueling work is composed of an AND condition between a predetermined set refueling target and a predetermined set refueling amount. If a non-self-service refueling work compulsory setting pattern consisting of only a predetermined set refueling amount is set in the compulsory setting table 50, such a compulsory setting pattern can also be determined in steps S220 and 230.

Therefore, according to the process shown in FIG. 6, the refueling work that the customer is about to perform in steps S220 and 230 is among the compulsory setting patterns No. 1, No. 2, and No. 3 of the non-self-service refueling work. If it is determined that any of the above is applicable, a non-self-service refueling operation is set, and as shown in FIG. 7, if the person in charge is not in the refueling work area 2, the weighing machine control device 16 is set. It becomes impossible to start the actual refueling to the refueling target 3 by operating the nozzle 12.

On the other hand, in steps S220 and 230, the refueling work that the customer is about to perform is in any of the compulsory setting patterns No. 1, No. 2, and No. 3 of the non-self-service refueling work. If it is determined that this is not the case, the self-service refueling operation set in step S070 of FIG. 4 is maintained, and the weighing machine control device 16 does not perform the process shown in steps S250 to 266. As shown in FIG. 7, even if the staff is not in the refueling work area 2, the customer can operate the nozzle 12 to start the actual refueling to the refueling target 3.

FIG. 7 shows the refueling work information including "(1) set refueling target", "(2) set oil type" and "(3) set refueling amount" selected and set by the refueling terminal 20 as described above. Based on this, the execution control of the refueling operation using the corresponding refueling system 11 of the weighing machine 10 by the measuring machine control device 16 is shown.

The weighing machine control device 16 is set with refueling work information including "(1) set refueling target", "(2) set oil type", and "(3) set refueling amount", and about the refueling work to be performed from now on. When the setting of the refueling work information is completed, whether or not the refueling work permission has been supplied from the refueling management machine 40 to the measuring machine 10 waiting for the refueling work permission or the corresponding refueling system 11 of the measuring machine 10. Is being monitored (S310).

Further, the weighing machine control device 16 monitors the supply of the refueling work permit from the refueling management machine 40, and whether or not the nozzle 12 of the corresponding refueling system 11 is operated and the actual refueling work for the refueling target 3 is started. Is monitored according to whether or not the nozzle removal detection is input from the nozzle detector provided in the nozzle storage unit 14 of the corresponding refueling system 11 (S320).

When the weighing machine control device 16 confirms in step S310 that the refueling work permit is supplied from the refueling management machine 40, and confirms in step S320 that the actual refueling work for the refueling target 3 has started, it is confirmed. Based on the setting memory contents, whether the refueling work for the refueling target by the corresponding refueling system 11 to be performed is set to the non-self-service refueling work or the self-service refueling work. Confirm (S330).

In addition, when the weighing machine control device 16 determines in step S330 that the refueling work for the refueling target by the corresponding refueling system 11 is set to the non-self-service refueling work, the staff member further Whether or not the measuring machine 10 is located in the refueling work area 2 is determined based on the input of the staff location detection signal from the staff detector 60 (S340).

Then, in step S330, the weighing machine control device 16 sets the refueling work for the refueling target by the corresponding refueling system 11 to be performed to the self-service refueling work instead of the non-self-service refueling work. When, or even if the non-self-service refueling work is set, when it is determined in step S340 that the staff member is located in the refueling work area 2 of the weighing machine 10, the corresponding refueling is performed. "(1) Set refueling target" and "(2) Set oil set" set by the operation of the setting device 21 of the refueling terminal 20 by activating the liquid feeding device in the system 11 to start the fuel feeding to the nozzle. Actual refueling for the refueling target 3 based on the refueling work information including "seed" and "(3) set refueling amount" is started (S350).

After that, the weighing machine control device 16 detects that the actual refueling work for the refueling target has been completed in step S360 from the nozzle detector provided in the nozzle storage portion 14 of the corresponding refueling system 11. When it is determined by inputting, the liquid feeding equipment in the corresponding refueling system 11 is stopped, and the refueling data such as the refueling amount in the refueling work of the corresponding refueling system 11 is not shown in the refueling terminal 20, the refueling management machine 40, The refueling work end processing of the corresponding refueling system 11 is performed by appropriately outputting the data to a point-of-sale information management machine (POS) or the like (S370).

If "(3) Set refueling amount" in the refueling work information is a fixed amount or a fixed amount other than "full tank", when the refueling corresponding to the fixed amount or the fixed amount has already been completed, it is sent in the corresponding refueling system 11. Since the liquid device has already been driven and stopped by the weighing machine control device 16, it is possible to omit the drive stop of the liquid feeding device in step S360.

As a result, the slip issuing unit 29 of the refueling terminal 20 issues a settlement slip in which the slip number, the amount of refueling, the refueling price, etc. are described (S380), and the measuring machine control device 16 stores the slip. The refueling work information about the refueling work is reset (S390).

As described above, when the self-service refueling work is set by performing the execution control of the refueling work shown in FIG. 7, the weighing machine control device 16 has the presence or absence of the staff by the staff detector 60. Regardless of the detection result of, while allowing the corresponding refueling system 11 of the corresponding measuring machine 10 to send liquid to the nozzle 12, if the non-self-service refueling work is set, the staff detector 60 is used. When the location of the person in charge is not detected, it functions as a supply control unit that does not send the remaining unset refueling work information to the nozzle 12 to the refueling system 11 of the measuring machine 10.

Therefore, according to the refueling system 1 of the present embodiment, even if the staff at the refueling management machine 40 permits the fuel supply operation of the measuring machine 10 at the self-service gas station, the nozzle 12 is operated to refuel. When a non-self-service refueling work by a staff member is required to start the actual refueling for No. 3, the non-self-service refueling work is set by the weighing machine control device 16 of the corresponding measuring machine 10. ..

As a result, when the non-self-service refueling work is set, the corresponding measuring machine 10 sets the refueling work information by the refueling terminal 20 if the staff is not located in the refueling work area 2 of the corresponding measuring machine 10. Is not possible even during the setting, and even if the nozzle 12 of the measuring machine 10 is operated to start the actual refueling to the refueling target 3, the fuel supply operation of the measuring machine 10 is prohibited. Refueling work cannot be performed.

As a result, according to the refueling system 1 of the present embodiment, when refueling a small-capacity shallow tank such as a "carrying can / plastic tank", a staff member in the refueling work area 2 of the corresponding measuring machine 10 Refueling can only be performed by setting the remaining unset refueling work information (that is, oil type and refueling amount) and operating the nozzle 12 of the measuring machine 10 to perform the refueling work. Therefore, the customer himself normally operates the nozzle to start the actual fuel supply without reducing the discharge flow rate from the nozzle, and the fuel bubbles generated in the tank due to the fuel supply suddenly become the tank. It is possible to prevent the fuel from overflowing from the fuel supply port.

In addition, when there is a high possibility that there is an error or abnormality in the setting contents of the supply work information set by the customer (for example, in the illustrated example, "light vehicle" and "light oil" are selected as the set refueling target and the set oil type. In this case, or when "motorcycle" and "40 [L]" are selected for the set refueling target and the set refueling amount ) , the staff will go to the work area 2 of the corresponding weighing machine 10 and make additional confirmation at the site. Otherwise, the customer cannot operate the nozzle 12 of the measuring machine 10 to actually start refueling the refueling target 3. As a result, it is possible to prevent the occurrence of inappropriate situations such as the customer supplying the oil liquid of the wrong oil type to the refueling target.

The embodiment of the fuel supply system according to the present disclosure is not limited to the configuration of the refueling system 1 of the above-described embodiment, and various changes and substitutions are possible.

For example, in the fuel supply system 1 of the above-described embodiment, the refueling work for which the measuring machine control device 16 of the measuring machine 10 is to be operated by operating the nozzle is either a self-service refueling work or a non-self-service. Refueling target 3 depending on whether self-service refueling work is set or non-self-service refueling work is set by functioning as a work discriminating unit that determines whether the refueling work is a method Although the configuration is such that it also functions as a supply control unit that permits / prohibits actual refueling by the corresponding weighing machine 10 for the above, the refueling management machine 40 capable of transmitting and receiving control signals and information data is identified from these work. It is also possible to have a configuration that functions as a unit and a supply control unit.

Further, the clerk detector 60 is not limited to the configuration having the lock mechanism 61, the lock state detector 62, and the portable key 63, and the clerk carries a transponder in the weighing machine 10 or its refueling work area 2. , The configuration may be provided with a detector for detecting the transponder located in the refueling work area 2. Further, in this case, a transponder may be provided in the portable management machine terminal 41 of the refueling management machine 40.

Further, the fuel supply facility to which the fuel supply system 1 is applied is not limited to the self-service gas station as shown in FIG. 1, but is a facility that replenishes fuel (including driving power) to vehicles by self-service. In this case, the weighing machine 10 includes a fuel cell hydrogen filling device provided with a filling nozzle and a vehicle charging device provided with a charging nozzle.

As described above, the fuel supply system according to the present disclosure is set by operating a setting device for setting supply work information related to the fuel supply work in advance and a nozzle provided at the tip of the hose when the fuel supply work is performed. There is no need for a staff member to supply fuel based on the metering machine that supplies fuel to the supply target based on the supply work information set by the device and the supply work information related to the fuel supply work set by the set device. A work discriminating unit that determines whether the fuel supply work is a self-service type by the customer or a non-self-service type fuel supply work that requires a fuel supply work by a staff member, and a non-self-service by the work discriminating unit. If it is determined that the fuel supply work is of the type, if it is equipped with a supply control unit that prohibits the weighing machine from sending fuel to the nozzle, there are various specific configurations. It can be replaced or changed.

Then, according to the fuel supply system according to the present disclosure, it is determined that the fuel supply work to be performed is a non-self-service fuel supply work based on the supply work information set by the setter. At that point, the fuel supply work will continue if the staff operates the weighing machine in the refueling work area or if the staff in the refueling work area does not confirm, the subsequent fuel supply work will proceed. Since this is not possible, the customer does not have to perform unnecessary supply work information setting operations, and the staff does not need to cancel the extra supply work information set by the customer in the fuel supply work. It is possible to improve the efficiency of each customer and staff.
