Description

  The present invention relates to a maintenance management system and a maintenance management device for remotely monitoring and managing an abnormality or a sign of a failure occurring in each device provided in a fuel supply device. In particular, the present invention provides maintenance for remotely monitoring and managing abnormalities and signs of failure occurring in each device of a fuel supply device installed in a fuel supply station and replenishing vehicles such as gasoline, light oil, and natural gas. The present invention relates to a management system and a maintenance management device.

  There is a self-service fueling system in which a fueling customer himself operates a metering machine to perform a fueling operation as one method of a fueling system representative of a fuel supply station. In this self-service fueling system, the fueling customer stops the vehicle in the vicinity of the metering machine as the fuel supply device, removes the fueling nozzle stored in the nozzle hook of the metering machine, and uses the cylinder tip as the fueling port of the vehicle. Insert and perform the refueling work by operating the nozzle lever. Further, when the refueling work is finished, the refueling customer removes the refueling nozzle from the refueling port of the vehicle and puts it back on the nozzle hook of the measuring machine. Therefore, the weigher has a nozzle switch that detects the removal / retraction of the fuel nozzle relative to the nozzle hook, and in conjunction with the refueling permission by the gas station staff, this nozzle switch is linked to ON (removal) / OFF (retraction). Devices such as a pump that is driven / stopped, a flow meter that measures the flow rate of the oil discharged from the pump, a display that displays the amount of oil calculated based on the measurement output of the flow meter, and the like are provided.

  However, in such a self-service refueling system, the refueling customer directly operates the weighing machine directly to perform the refueling work, so even if signs of abnormality or failure appear in these equipment during refueling work, Without a special offer from the customer, the gas station staff cannot immediately feel this. For this reason, the staff at the gas station will know the abnormality or the sign of the failure as a failure of the weighing machine when these devices have actually failed and the refueling work cannot be performed with the weighing machine. We will ask for repair.

JP 2003-12100 A

  Conventionally, in such a case, a repairman of a maintenance company, etc., travels to a fuel supply station in response to a request for repair of the fuel supply apparatus from a fuel supply station that is a maintenance customer, and each of the fuel supply apparatuses that have failed at the site. Inspect the equipment, and if the fault is found, repair it by replacing parts.

  However, as described above, the failure point is found by a repairman inspecting each device of the fuel supply device at the fuel supply station. If you have not prepared it, you cannot repair the fault on the spot. In such a case, the repairman has to revisit the fuel supply station to repair the failed part, and the work efficiency is deteriorated. During this time, the fuel supply station could not use the failed fuel supply device, so the customer service had to be reduced.

  Therefore, the status of each device of the fuel supply system installed at each fuel supply station is remotely monitored by a maintenance company, etc., and the signs of abnormality or failure of each device are analyzed and detected by the maintenance company etc. based on the operating status. Thus, a maintenance management system that performs maintenance and repair work on the fuel supply device at an appropriate timing can be considered. When such a maintenance management system is implemented, a method for performing the maintenance / repair work becomes a problem.

  For example, there are various phenomena even if it is a sign of abnormality or failure of each device of the fuel supply device. For example, when the discharge amount is lower than usual, it is expected that the filter or strainer of the pump is clogged, the belt that transmits the rotation of the motor to the pump is loosened, and the like. Moreover, when the discharge amount is excessive with respect to the normal amount, oil leakage from piping, hoses, etc. must be assumed as the cause. Therefore, as a sign of abnormality or failure, if the discharge amount is excessive compared to the normal amount, oil leakage must also be assumed. The risk of the failure phenomenon itself is high, and immediate priority treatment is required for safety.

  Therefore, in the maintenance management system described above, the priority of the start of maintenance / repair work is set in accordance with the signs of abnormality or failure of each device of the fuel supply device provided at each fuel supply station, and the maintenance company It is preferable to perform maintenance / repair work of each device of the fuel supply device in accordance with this priority order.

  However, even if priority is set for the start of maintenance / repair work, conversely, in the case of abnormalities or signs of failure, such as pump filters or strainers being clogged, the pipes and hoses mentioned above In the case of a high-priority abnormality or a sign of failure that must also assume oil leaks, etc., maintenance and repair work will be postponed. Also, in general, such low-priority abnormalities and signs of failure do not greatly disturb the fuel supply operation, and there are abnormalities and failures in the fuel supply staff as refueling customers and maintenance customers. The signs are difficult to understand, and as a result, the inspection, maintenance and repair work may be left unattended until the regular inspection.

  The present invention aims to solve the above-described problems, and improves the efficiency of maintenance / repair work, that is, maintenance work for signs of abnormality or failure occurring in each device provided in the fuel supply device. It is another object of the present invention to provide a maintenance management system and a maintenance management device that prevent a maintenance / repair operation with a low priority from being delayed and left unattended, and improve service to maintenance customers.

In order to solve the above problems, a maintenance management system according to the present invention is acquired by a maintenance information acquisition unit that acquires operation information of equipment provided in a fuel supply device that supplies fuel, and the maintenance information acquisition unit. An abnormal state detection unit that detects an abnormal state from the operation information of the device, a maintenance operation based on the abnormal state detected and output from the abnormal state detection unit, a determination unit that determines the priority of the maintenance operation, and the determination unit A scheduled work recording means for accumulating the determined maintenance work and the priority of the maintenance work, a priority comparison means for comparing the priority determined by the determination means with a predetermined predetermined priority, According to the comparison result of the priority comparison means, the determined priority is higher than a predetermined priority. To, together with maintenance work of the fuel supply device for accumulating the work scheduled recording means, the work scheduled recording means is already accumulated, the same group as the group which are assigned in advance for the fuel supply system Further, it is characterized in that it comprises a notifying means for notifying the maintenance work of other fuel supply devices that are grouped in advance regardless of the priority of the maintenance work .

The maintenance management device according to the present invention is a maintenance management device that receives a maintenance request for a fuel supply device provided in the fuel supply station, which is transmitted from each fuel supply station, and stores and manages the request in the storage means. A comparison means for determining a priority of maintenance work based on the received maintenance request of the fuel supply device for each reception of the request, and comparing the determined priority with a predetermined predetermined priority; and the comparison means comparison result according to, wherein when the determined priority is higher than a predetermined priority which is determined in advance, together with the maintenance of the maintenance request of the fuel supply system is determined that the priority is high, In the same group as the group assigned in advance to the fuel supply devices stored in the storage means and determined to have a high priority. Characterized in that also the maintenance work based on maintenance request of another fuel supply device are grouped and a notifying means for informing regardless of the priority of the maintenance work.

In the maintenance management device of the present invention , each fuel supply device is grouped in advance for each fuel supply station or for each fuel supply station series .

In the maintenance management device of the present invention , each fuel supply device is grouped in advance for each predetermined area .

In the maintenance management device of the present invention , each fuel supply device is grouped in advance for each type of fuel supply device .

  According to the maintenance management system and the maintenance management device of the present invention, only when a maintenance operation with a high priority occurs with respect to a maintenance operation for an abnormality or a sign of a failure occurring in each device provided in the fuel supply device, Since the occurrence is automatically notified, the urgency can be reliably identified and grasped.

  Further, according to the maintenance management system and the maintenance management device of the present invention, when a maintenance work with a high priority has occurred regarding a maintenance work for an abnormality or a sign of a failure that has occurred in each device provided in the fuel supply device, In addition to the notification of the occurrence, the low-priority maintenance work that has already been accepted and not actually performed is automatically notified together, so the low-priority maintenance work is delayed and left behind. To prevent this and improve service to maintenance customers.

  And the notification of maintenance work with low priority that has not been actually performed is not simply notified together every time a new maintenance work is accepted, but the newly received maintenance work has high priority. Only in certain cases, it is automatically notified together with the notification of its occurrence, so it is highly urgent in the group such as the same fuel supply station, the same location area, the same management series, the same fuel supply device type, etc. In relation to maintenance work with high priority, it is possible to actively carry out maintenance work with low priority that has not been actually performed, and maintenance work with low priority is delayed and left behind. Can be improved.

  As an embodiment of the maintenance management system of the present invention, a maintenance management system that performs maintenance of each device provided in a weighing machine of a gas station that supplies fuel to a vehicle will be described with reference to the drawings.

The outflow side of the flow control valve 26 is connected to the base end side of the oil supply hose 27 having the oil supply nozzle 28 connected to the distal end side. The flow rate pulse output from the flow rate pulse transmitter 25 is supplied to the weighing machine control means 30 provided in the main body 21 to calculate the amount of oil supplied, and the calculated amount of oil supplied is displayed on the display 29. The Further, the main body 21 includes a nozzle hook 31 for storing the fuel nozzle 28, a nozzle switch 32 that is turned on / off in response to the removal / retraction of the fuel nozzle 28 with respect to the nozzle hook 31, a desired preset value (preset A preset device 33 is provided for setting and inputting preset oil supply (quantitative oil supply) by setting and inputting an oil supply amount or preset amount). Further, the motor 23 is provided with a temperature sensor 34 for detecting abnormal heating of the motor 23.

  In addition to the flow rate pulse transmitter 25 and the indicator 29 described above, a motor 23, a flow rate control valve 26, a nozzle switch 32, a preset device 33, and a temperature sensor 34 are connected to the weighing machine control means 30.

  Thereby, in the maintenance management system 1 of this Embodiment, the weighing machine control means 30 becomes a structure which functions also as each part described below besides functioning as an oil supply amount calculating / display part as mentioned above. .

  The weighing machine control means 30 drives / stops the motor 23 and opens / closes the flow rate control valve 26 according to the detection output of the nozzle switch 32 to control the supply of oil to the oil supply nozzle 28. As the liquid supply control unit, the flow rate control valve 26 is controlled to close based on the preset value set and input from the preset device 33, and the oil supply corresponding to the preset value is operated by the nozzle lever of the fuel supply nozzle 28 (valve closed). It also functions as a preset lubrication control unit that automatically ends regardless of the operation.

  Further, the weighing machine control means 30 calculates the integrated amount as the sum of the amount of oil supplied by the weighing machine 20 based on the flow rate pulse supplied from the flow rate pulse transmitter 25 or the oil supply using the weighing machine 20. It also functions as a maintenance information acquisition unit that measures the number of operations (approximately equivalent to the number of times the pump 22 of the weighing machine 20 is started / stopped) and acquires operation information of the weighing machine 20.

  The weighing machine control means 30 determines whether or not the motor temperature of the activated motor 23 is within a preset allowable temperature range (for example, 60 ° C. or less) based on the detection output of the temperature sensor 34. The amount of oil discharged from the pump 22 (in this case, corresponding to the flow rate per unit time) is measured based on the flow rate pulse that is monitored or supplied from the flow rate pulse transmitter 25. Whether or not the discharge amount deviates from a predetermined allowable discharge amount range (for example, 20.00 to 40.00 L / min) under a predetermined condition (for example, the lever fully opened operation state). An abnormality monitoring detection unit that monitors or monitors whether or not the actual refueling with respect to the preset value deviates from a predetermined allowable error range (for example, 0.05 L) in the case of preset refueling. Also functions.

  In order to function as each of the above-described units, the weighing machine control means 30 is provided with a memory 35. The memory 35 stores programs and data for causing the weighing machine control means 30 to function as an oil supply amount calculation / display unit, a liquid supply control unit, a preset oil supply control unit, a maintenance information acquisition unit, and an abnormality monitoring detection unit. ing.

  The weighing machine control means 30 is connected to the gas station management terminal device 40 installed in the office of the self gas station Ai via the above-described communication line 50 in the gas station.

  The gas station management terminal device 40 of the present embodiment is configured to supply, for example, the type of oil to be supplied to the vehicle, etc., from the measuring device control means 30 of each measuring device 20 in the self-service station Ai via the communication line 50 in the service station. In addition to the refueling information such as the amount, the refueling amount, etc., the operation information and abnormality detection information of the measuring machine 20 are received. Here, as the operation information of the weighing machine 20, the integrated amount and the number of refueling operations described above are applicable, and as the abnormality detection information, the motor temperature described above deviates from a preset allowable temperature range (60 ° C. or less). Information on motor overheating in the case of discharge, information on decrease in discharge amount or excessive discharge amount information when the discharge amount from the pump 22 deviates from the allowable discharge amount range (20 L / min to 40 L / min), preset value at the time of preset lubrication This corresponds to the quantitative over-information when the actual refueling deviates from the allowable error range (0.05L). In the case of preset lubrication, if the actual amount of lubrication is insufficient with respect to the preset value and deviates from the measurement allowable error range (0.05L), the above-described preset lubrication control unit automatically performs additional lubrication. For this reason, insufficient quantification with respect to the preset value cannot occur, and the insufficient quantification information is not transmitted as abnormality detection information from the weighing machine control means 30 of each weighing machine 20.

  The filling station management terminal device 40 receives the filling information and operation information transmitted from each measuring machine 20 via the in-filling station communication line 50, and performs the filling management and maintenance management as a whole of the self-filling station Ai. In addition, the gas station management terminal device 40 generates a maintenance request for the maintenance company B when it receives abnormality detection information from any of the measuring machines 20 provided in the self-gas station Ai.

It has a storage device 42 for storing refueling management information, maintenance management information, etc. as a whole self-service station Ai generated by the refueling station processing device 41. The gas station management terminal device 40 can also be connected to the maintenance management device 10 of the maintenance company B via the communication line 60.

  The maintenance management device 10 of the maintenance company B includes, for example, a maintenance processing device 11 constituted by a personal computer, maintenance requests from the gas stations A1 to An acquired by the maintenance processing device 11, and maintenance processing based on this. And a database 12 for storing maintenance information generated by the apparatus 11 such as a maintenance process plan / progress status performed by the maintenance company B.

  Next, the control configuration of each part of the maintenance management system 1 of the present embodiment configured as described above will be described.

<Weighing machine>
FIG. 3 is a flowchart showing the control configuration of the weighing machine.
After being activated, the weighing machine control means 30 of the weighing machine 20 is always on standby, the oil supply nozzle 28 is removed from the nozzle hook 31, the nozzle switch 32 is closed (on), and the oil supply operation is started. It is monitored whether or not (step S11). For example, the weighing machine control means 30 detects the closing of the nozzle switch 32 in a situation where the refueling permission is supplied from the refueling station management terminal device 40 via the communication line 50 in the refueling station. Start preparation processing. As a start preparation process for the current refueling operation, the weighing machine control means 30 resets the oil supply amount counter to zero in order to measure the refueling amount for the current refueling operation (step S12), starts the motor 23, and activates the pump 22. While starting to drive (step S13), the flow control valve 26 is opened (step S14), and the supply of the oil liquid to the oil supply nozzle 28 is started.

  In a state where the start of preparation is made, when the refueling customer opens the nozzle lever of the refueling nozzle 28 and actual refueling is started, the measuring machine control means 30 of the measuring machine 20 refuels the refueling work of this time Perform medium processing.

  The weighing machine control means 30 counts the flow rate pulse output from the flow rate pulse transmitter 25 with an oil supply amount counter and displays the amount of oil supply based on the counted value on the display unit 29 as an operation process during the current refueling operation. (Step S15).

  Further, the weighing machine control means 30 calculates the discharge amount during the current refueling operation based on the flow rate pulse supplied from the flow rate pulse transmitter 25 per unit time, and based on the detection output of the temperature sensor 34. The motor temperature of the motor 23 is calculated. For example, when the measured discharge amount and motor temperature are the maximum values during the current refueling operation, the weighing machine control means 30 uses the values as the discharge amount and motor temperature during the current refueling operation, for example. The discharge amount storage unit 36 or the motor temperature storage unit 37 (both refer to FIG. 4 described later) formed in the memory 35 is stored (step S16).

  Further, the meter control means 30 also terminates the actual refueling operation by the refueling nozzle 28 being returned to the nozzle hook 31 and the nozzle switch 32 being opened (off) during the measurement operation in the current refueling operation. Monitoring is performed (step S17).

  In this way, during actual refueling, the weighing machine control means 30 repeatedly performs the processing shown in steps S15 to S17 described above, calculation display of the refueling amount during the current refueling operation, discharge amount and motor temperature. Update memory.

  Thereafter, the customer performs a valve closing operation on the nozzle lever of the fueling nozzle 28 and returns it to the nozzle hook 31. When the current fueling operation is completed, the meter control means 30 of the metering machine 20 performs a fueling end process.

  The weighing machine control means 30 closes the flow rate control valve 26 (step S18), stops the motor 23 and stops driving the pump 22 (step S19) as a refueling end process of the current refueling operation. The supply of the oil liquid to 28 is stopped. Although omitted in the above description, when the preset refueling operation is set by operating the preset device 33 at the start of actual refueling in the current refueling operation, the refueling nozzle 28 is returned to the nozzle hook 31. Even before, when the fueling corresponding to the preset value is completed, for example, the flow control valve 26 is automatically closed by the preset fueling control unit of the meter control unit 30, so that the fueling nozzle 28 is closed. The supply of oil has already been stopped.

  Thereafter, the weighing machine control means 30 integrates the amount of oil supplied during the current refueling operation until the previous refueling operation held in an integrated amount storage unit 38 (see FIG. 4 described later) formed in the memory 35. Add to the amount Q, update and store as a new integrated amount Q, and refuel until the previous refueling operation held in a refueling operation number storage unit 39 (see FIG. 4 described later) that is also formed in the memory 35. The operation information is updated as the maintenance information acquisition unit, such as incrementing the number of operations and updating and storing the number of refueling operations (step S20).

FIG. 4 is a configuration explanatory diagram of the above-described integrated amount storage unit, refueling operation number storage unit, discharge amount holding unit, and motor temperature holding unit formed in the memory of the weighing machine.
FIG. 4 shows, for example, that the memory 35 has an integrated amount storage unit 38, a refueling operation number storage unit 39, a discharge amount storage unit 36, a motor for each data type such as integrated amount, number of refueling operations, discharge amount, motor temperature, and the like. It shows that a predetermined storage area such as the temperature storage unit 37 is provided. In FIG. 4, the actual refueling operation is finished, and each of the parts 36 to 39 has a discharge amount = 35.00 L / min, a motor temperature = 40.0 ° C., an integrated amount = 12,000 KL, a refueling operation count = 5, A state in which 000 times are stored is illustrated.

  Then, the weighing machine control means 30 is prestored and held in the memory 35 in the same manner as the abnormality monitoring detection unit for the refueling information during the current refueling operation and the operation information stored in the respective units 36 to 39 of the memory 35. Based on the determination reference data Dj (see FIG. 5) for each error information, abnormality monitoring detection processing for each device provided in the weighing machine 20 is performed.

FIG. 5 is an explanatory diagram showing a list of determination reference data for each error information stored and held in advance in the memory of the weighing machine.
In this embodiment, the memory 35 stores, for example, determination criterion data Dj for each error information as shown in FIG. 5 in association with each error code E in a predetermined error determination criterion storage area. Yes.

  For example, in FIG. 5, Dj01 (20.00 L / min) is determination reference data Dj for reducing the discharge amount, and error code E corresponds to E01, and Dj02 (40.00 L / min) is for excessive discharge amount. The error code E corresponds to E02 in the determination reference data, Dj03 (0.05L) corresponds to the determination reference data for over-quantity, ie, preset error, and the error code E corresponds to E03, and Dj04 (60.0 ° C.) corresponds to the motor. It is shown that the error code E corresponds to E04 in the criterion data for overheating, that is, the motor temperature rise.

  Returning to FIG. 3, when the current refueling operation is completed, the weighing machine control means 30 first performs abnormality detection of the discharge amount reduction in the abnormality monitoring detection processing thereafter, for example, in the case of the present embodiment (step S <b> 21). . The abnormality detection of the discharge amount reduction is performed by detecting that the discharge amount at the current refueling operation, that is, the discharge amount stored in the discharge amount storage unit 36 shown in FIG. The determination is made based on whether or not it is equal to or less than the determination reference data Dj01. When the weighing machine control means 30 determines that an abnormality in the discharge amount reduction has occurred, the abnormality recording area (not shown) formed in the memory 35 has abnormality information during the current refueling operation. The error code E01 is temporarily stored (step S22).

  Next, in the case of the present embodiment, the weighing machine control means 30 performs an abnormal discharge detection process for excessive discharge amount (step S23). In the same manner, the abnormality detection of the excessive discharge amount is performed so that the discharge amount stored in the discharge amount storage unit 36 shown in FIG. 4 during the current refueling operation is equal to or higher than the criterion data Dj02 for the excessive discharge amount shown in FIG. The determination is made based on whether or not. When the weighing machine control means 30 determines that an abnormality of excessive discharge amount has occurred, the error code E02 is temporarily stored in the above-described abnormality recording area of the memory 35 as abnormality information during the current refueling operation. (Step S24).

  Next, in the case of the present embodiment, the weighing machine control means 30 performs an abnormal monitoring detection process for abnormal overheating of the motor 23 (step S25). The abnormality detection of the motor abnormal overheating is that the motor temperature held in the motor temperature storage unit 37 shown in FIG. 4 during the current refueling operation is equal to or higher than the criterion data Dj04 for motor abnormal overheating shown in FIG. Whether or not the determination is made. When the weighing machine control means 30 determines that an abnormal overheating of the motor 23 has occurred, the error code E04 is temporarily stored in the above-described abnormality recording area of the memory 35 as abnormality information during the current refueling operation. (Step S26).

  Furthermore, in the case of the present embodiment, the weighing machine control means 30 performs an over-quantification, that is, a preset error abnormality monitoring detection process (step S27). In this over-quantitative abnormality detection, the weighing machine control means 30 first automatically terminates the actual refueling operation during the current refueling operation by automatically operating the flow control valve 26 by the preset refueling control unit corresponding to the preset value from the preset device 33. It is determined whether the valve is closed or normal oil supply is performed by operating the lever of the oil supply nozzle 28 (step S27). In addition, when the current refueling operation is normal refueling, the weighing machine control means 30 ends the over-monitoring abnormality monitoring detection process. On the other hand, when the current refueling operation is preset refueling, the weighing machine control means 30 has an error in the amount of refueling due to actual refueling with respect to the preset value because the quantitative amount shown in FIG. It is determined whether or not the determination reference data Dj03 is greater than (step S28). As a result, when the weighing machine control means 30 determines that an abnormality of over-quantity has occurred, the error code E03 is displayed as abnormality information during the current refueling operation in the abnormality recording area of the memory 35 described above. Store (step S29).

  As described above, the weighing machine control means 30 performs the reporting process for the current refueling operation when the abnormality monitoring detection process for the current refueling operation described in steps S21 to S29 is completed.

  In this reporting process, it is confirmed whether or not even one error code E (E01 to E04) regarding the abnormality during the current refueling operation is temporarily stored in the abnormality recording area of the memory 35 (step S30). If no error code E is stored in the abnormality recording area of the memory 35 as a result of this confirmation, the weighing machine control means 30 provides fueling information such as the fueling amount calculated based on the count value of the fueling amount counter, For example, operation information such as the accumulated amount up to the current refueling operation, the number of refueling operations, and the like is transmitted to the refueling station management terminal device 40 via the refueling station communication line 50 in a predetermined data transmission format. On the other hand, when at least one error code E is stored in an abnormal recording area (not shown) of the memory 35, the weighing machine control means 30 is stored in addition to the above-described refueling information and operation information. All error codes E are transmitted as error information (step S31).

  In addition, the weighing machine control means 30, if it is confirmed that the transmission information is received by the gas station management terminal device 40, the value stored in the discharge amount storage unit 36 and the motor temperature storage unit 37 in the memory 35. And the control process of the weighing machine 20 for the current refueling operation is terminated.

<Gas station management terminal device>
In the case of the maintenance management system 1 according to the present embodiment, the gas station management terminal device 40 receives the oil supply information transmitted from the measuring machine control means 30 of each of the measuring machines 20 in the self-service station Ai each time the fueling operation is performed. When the operation information and error information are received, the following processing is performed.

  The gas station processing device 41 of the gas station management terminal device 40 performs a slip issuing process for the fueling customer regarding the current fueling work based on the received fueling information such as the type of fueling oil, the amount of fueling, and the amount of fueling. Data is stored and stored in the storage device 42 as refueling management information.

In addition, the gas station processing device 41 performs maintenance management of all the metering devices 20 provided in the self-gas station Ai based on the received operation information such as the accumulated amount received, the number of oiling operations, and the like. For example, the gas station processing device 41 updates a measuring machine maintenance management table (not shown) stored in the storage device 42. The weighing machine maintenance tube retainer Buru, weighing machine 20 separately, the accumulated amount, in addition to the operating information such as the refueling operation number of times, also described below outgoing track record of maintenance request to the maintenance company B, etc. has become to be recorded .

  Further, when the gas station processing apparatus 41 receives error information based on the error code E from the weighing machine 20, it creates and sends a maintenance request to the maintenance company B. Therefore, in the maintenance management system 1 of this Embodiment, the gas station processing apparatus 41 functions as a maintenance request preparation transmission part.

Therefore, in the gas station processing device 41, transmission destination data such as a transmission telephone number and a transmission address for the maintenance company B are registered in advance in its memory or storage device 42 (not shown). When the gas station processing device 41 receives the error information from the measuring machine 20 by the error code E, the error code E includes, for example, the gas station identification data Gi, the weighing machine identification data Si, the integrated amount Q, and the number of refueling operations. A predetermined maintenance request configured by adding necessary information such as operation information data is created. On top of that, the gas station processor 41, the maintenance request, and transmits a predetermined communication scheme via the communication line 60 based on the destination data described above, the outgoing proven weighing machine maintenance tube retainer Buru Record.

<Maintenance management device>
In the case of the maintenance management system 1 according to the present embodiment, when the maintenance management device 10 of the maintenance company B receives a maintenance request including error information transmitted from the gas station processing device 41 of each gas station Ai, the priority level The following processing is performed as a determination unit, a registration unit, and a notification unit.

FIG. 6 is a flowchart showing a control configuration of the maintenance management apparatus.
In FIG. 6, the maintenance management device 10 of the maintenance company B always confirms whether or not a maintenance request from the gas station management terminal device 40, that is, whether or not error information is received (step S51). Then, when a maintenance request from the gas station management terminal device 40, that is, reception of error information is confirmed by the maintenance processing device 11 of the maintenance management device 10, an error code E (for example, error information included in the maintenance request) Maintenance process based on requested configuration data such as one of error codes E01 to E04 shown in FIG. 5), gas station identification data Gi, weighing machine identification data Si, accumulated quantity Q, and operation information data such as the number of refueling operations. The device 11 performs the following processing.

  First, the maintenance processing apparatus 11 is based on the maintenance record database 13 provided in the database 12 based on the weighing machine identification data Si (for example, 00 ≦ i ≦ 99) in which the abnormality included in the received maintenance request has occurred. A maintenance record Dm (Si) of the corresponding weighing machine identification data Si is extracted (step S52).

FIG. 7 is an explanatory diagram of a maintenance record database provided in the database.
The maintenance record database 13 adds the maintenance code M corresponding to a predetermined maintenance code M for each maintenance work content W for which the work has actually been completed. , Weighing machine identification data Si), operation information (for example, integrated amount Q at the time of maintenance), and the like are recorded.

  For example, in FIG. 7, seven maintenance work contents represented by maintenance codes M01, M01, M02, M06, M08, M01, and M03, respectively, for the weighing machine 20 of the weighing machine identification data S01, 90, 1900, 1900, 2500, 2500, 2500, 2500 KL are recorded. Therefore, if the maintenance record Dm (S01) of the weighing machine identification data S01 is extracted, seven maintenance records Dm (S01) 1 to Dm (S01) 7 for the weighing machine identification data S01 are extracted. It will be.

  The maintenance record Dm of the maintenance record database 13 is a scheduled work that has been completed from the scheduled work database 15 every time the maintenance company B inputs the completion of the maintenance work listed in the scheduled work database 15 described later. Data is transferred and additionally updated. For example, in the case of FIG. 7, when the integrated amount Q is 2500 KL, maintenance records Dm (S01) 4 to Dm (S01) 7 of four maintenance operations respectively represented by maintenance codes M06, M08, M01, and M03 are added. It is shown that it has been updated.

  Returning to FIG. 6, next, the maintenance processing apparatus 11 is based on the maintenance record Dm (Si) of the corresponding weighing machine identification data Si extracted from the maintenance record database 13 and the received error information (error code E). Then, the corresponding inspection contents are extracted (step S53). This inspection content extraction is performed with reference to, for example, the inspection content / priority determination table 14 set and recorded in advance in the memory of the maintenance processing apparatus 11.

FIG. 8 is an explanatory diagram of the inspection content / priority determination table set and recorded in advance in the memory of the maintenance processing apparatus.
The inspection content / priority determination table 14 includes, for each error code E (error information), a determination condition R and a determination code J for the maintenance work content (inspection content) W, and one or more maintenance codes M for the determination code J. The maintenance work W represented by, and the priority Y for carrying out the maintenance work W are set and stored with a corresponding relationship.

  In the inspection content / priority determination table 14 illustrated in FIG. 8, three determination conditions R are provided for the error information E of the discharge amount reduction represented by the error code E01 illustrated in FIG. 5. For each R, that is, for each determination code J, the maintenance work W represented by one or a plurality of maintenance codes M is selected.

  For example, when the error information E is a discharge amount decrease of the error code E01, three judgment conditions are used in relation to the maintenance work W at the time of the latest latest discharge amount decrease extracted using the integrated amount Q as a parameter. R is preset. In addition, according to the determination codes J011 to J013 as the determination results, the maintenance work W represented by the maintenance code M01, the maintenance work W represented by the maintenance codes M01 and M02, or the maintenance codes M01 and M03, respectively. One of the maintenance works W to be selected is selected, and the priority Y is also determined. If the error information E is a decrease in the discharge amount of the error code E01, the priority Y becomes the same priority Y3 (however, Y3 <Y2 <Y1) even if the content of the maintenance work W is different. Yes.

  On the other hand, when the error information E is an excessive discharge amount of the error code E02, the determination condition R is not relevant, and the maintenance work W (that is, the maintenance work W represented by the maintenance codes M04, M05, and M06, respectively). Is set, and the priority Y is the highest priority Y1.

  Further, when the error information E is the motor temperature rise of the error code E04, a filter (integrated in the pump 22) represented by the latest maintenance code M01 using the integrated amount Q as a parameter, Two determination conditions R are set in advance in relation to “strainer cleaning / replacement”. Then, according to the determination codes J041 and J042 as the determination results, one of the maintenance work W represented by the maintenance code M09 or the maintenance work W represented by the maintenance code M01 is selected, and the priority Y is also set. It has come to be decided. When the error information E is an increase in the motor temperature of the error code E04, the maintenance work W selected based on the determination condition R is different from the case where the error information E is a decrease in the discharge amount of the error code E01. The priority Y is different.

  More specifically, based on the maintenance record database 13 shown in FIG. 7, the error code indicating the discharge amount decrease as the weighing machine identification data S01, the integrated amount Q = 3500 KL (3,500,000 L), and the error information E The inspection content extraction process shown in step S53 of FIG. 6 described above will be described by taking as an example a case where a maintenance request having E01 is received.

In this case, the maintenance processing device 11 extracts the maintenance record Dm (S01) of the weighing machine identification data S01 from the maintenance record database 13 shown in FIG. 7, and the maintenance work W represented by the latest maintenance codes M02 and M03. The integrated amount Q (M02) = 1,900,000L and Q (M03) = 2,500,000L at the time of carrying out are read out. On that basis, the maintenance processing device 11 adds the accumulated amount Q (M02) = 1,900,000 L, Q (M03) = 2 from the accumulated amount Q = 3500 KL (3,500,000 L) at the time of the latest implementation. Each of 500,000L is subtracted to determine which of the three determination conditions R shown in FIG. As a result, under the conditions described in FIG.
Q-Q (M02) = 3,500,000-1,900,000 = 1,600,000
Q-Q (M03) = 3,500,000-2,500,000 = 1,000,000
Therefore, the determination result is a determination code J012, and the maintenance work W represented by the maintenance code M01 (filter and strainer cleaning / replacement) and the maintenance code M02 (belt inspection / adjustment) has the priority Y3. Extracted as

  In this way, in the inspection content extraction process shown in step S53 of FIG. 6 described above, the maintenance work W and its priority Y are determined based on the inspection content / priority determination table 14 of FIG. 8 described above. Therefore, the optimum inspection contents can be automatically extracted based on the past maintenance work W results and the progress of the previous maintenance work W using the integrated amount Q as a parameter.

  Returning to FIG. 6 again, after the maintenance processing apparatus 11 performs the inspection content extraction process shown in step S53, the registration unit adds the priority Y, error code E, weighing machine identification data to the extracted inspection content. Scheduled work data Dw to which data such as Si, filling station identification data Gi, maintenance request reception date / time d / t, etc. is added is generated, and the generated scheduled work data Dw is stored on the scheduled work database 15 provided in the database 12. sign up.

FIG. 9 is a configuration diagram of an embodiment of a scheduled work database provided in the database.
In the case of the present embodiment, the scheduled work database 15 accumulates the scheduled work data Dw for each priority Y, in order of maintenance request reception date and time, that is, in order of occurrence of abnormality.

  When the maintenance processing device 11 registers the scheduled work data Dw generated in the scheduled work database 15, this time as a notification unit, the determined priority Y of the registered scheduled work data Dw is a predetermined priority set in advance. Hereinafter, for example, it is determined whether or not the priority is Y3 (step S55).

  Then, when the registered scheduled work data Dw is the scheduled work data Dw (6) shown in FIG. 9 and the determined priority Y is Y3 or less, the maintenance processing apparatus 11 performs the current maintenance. The control process for request reception ends.

  On the other hand, when the registered scheduled work data Dw is higher than the priority Y3 as shown in the scheduled work data Dw (1) shown in FIG. Then, the maintenance processing apparatus 11 performs a notification process according to a notification mode preset by the maintenance company B.

  Therefore, when performing the notification process, the maintenance processing apparatus 11 first checks the notification mode (step S56).

  As a result of the confirmation of the notification mode, if the preset notification mode is the priority order mode, the maintenance processing device 11 sorts the scheduled work data Dw registered in the scheduled work database 15 in order of priority Y ( In step S571), an unchecked list in order of priority Y is created, and the list is displayed on the display device, printed out from the printing device, or the like, and notified from the output means (step S581).

  In this priority order mode, the maintenance management apparatus 10 receives the scheduled work database 15 together with the scheduled work data Dw corresponding to the maintenance request only when a maintenance request including abnormality information with a high priority Y is received. The scheduled work data Dw of an unworked maintenance request recorded in is reported. For this reason, every time a maintenance company B at a maintenance company B receives a maintenance request including abnormality information having a high priority Y, the priority Y of the abnormality information included in the maintenance request is set together with the scheduled work data Dw corresponding to the maintenance request. The status of the scheduled work data Dw that is low and remains unworked can be confirmed.

  Next, when the preset notification mode is the same place mode, the maintenance processing device 11 selects the scheduled work data Dw registered this time from the scheduled work data Dw registered in the scheduled work database 15. The corresponding scheduled work data Dw is extracted by searching the identification data Gi (step S572), an unchecked list for the same gas station as shown in FIG. 10 is created, and the list is notified from the output means (step S582). ).

FIG. 10 is a diagram showing an example of an unchecked list for the same gas station.
In this same location mode, when the maintenance management device 10 receives a maintenance request including abnormality information with a high priority Y, the maintenance management device 10 gives priority to the abnormality information included in the maintenance request at the source gas station. If there is scheduled work data Dw whose degree Y is low and not yet worked, it is notified together with the scheduled work data Dw of the maintenance request including the received abnormality information with high priority Y. Therefore, every time a maintenance company B staff member receives a maintenance request including abnormality information with a high priority Y, it can check the scheduled work data Dw that has a low priority Y for the same gas station and is not working. It is useful for making a work plan to rationalize multiple maintenance work in a batch, and can prevent maintenance work that is not working because the priority Y is low and can improve the efficiency of the maintenance work. .

  Further, when the preset notification mode is the same group mode, the maintenance processing apparatus 11 selects the scheduled work data Dw registered in the scheduled work database 15 from FIG. 11 separately registered in the database 12 in advance. Based on the group table 16 as shown, the scheduled work data Dw belonging to the same group as the scheduled work data Dw registered this time is extracted (step S573), and an unchecked list for the same group as shown in FIG. 12 is created. The list is notified from the output means (step S583).

  Here, the group table 16 is configured by grouping data such as weighing machine identification data Si and gas station identification data Gi for each group such as the same location area, the same management series, the same weighing machine type, and the like. It is a recording table.

FIG. 11 is a diagram illustrating a group table for a gas station in the same location area as an example of the group table.
Therefore, when the scheduled work data Dw (1) shown in FIG. 9 is registered at this time, the maintenance processing device 11 is based on the group table shown in FIG. 11, and is the source gas station of the scheduled work data Dw (1). A gas station (represented by gas station identification data G25, G26) in the same location as the gas station (represented by gas station identification data G01) is extracted, and in addition to the source gas station, the scheduled work database 15 for this gas station as well. And the scheduled work data Dw (1), Dw (6), Dw (8) in the same location area as the scheduled work data Dw (1) registered this time are extracted (step S573). And the maintenance processing apparatus 11 produces the unchecked list | wrist about the same location area as shown in FIG. 12, and alert | reports the list from an output means (step S583).

FIG. 12 is a diagram showing an example of an unchecked list for the same group.
In this same group mode, when the maintenance management device 10 receives a maintenance request including abnormality information having a high priority Y, it is included in the maintenance request within a predetermined group including the maintenance request. If there is other scheduled work data Dw whose priority Y is low and has not been worked due to the abnormal information, the information is notified together. Therefore, every time a maintenance company B employee receives a maintenance request including abnormality information with a high priority Y, the priority Y within the same group, such as the same location, the same management line, the same measuring machine type, etc. is low. Since the unscheduled scheduled work data Dw can be confirmed, it is useful for making a work plan for rationally performing a plurality of maintenance tasks at once, and maintenance tasks that have low priority Y and are not yet performed. Can be prevented and maintenance work can be made more efficient.

  According to the maintenance management system and the maintenance management apparatus 10 of the present invention, regarding the maintenance work W for signs of abnormality or failure occurring in each device provided in the weighing machines 20A1m to 20Anm installed in the respective gas stations A1 to An. Since the occurrence is automatically notified only when the maintenance work W having a high priority Y occurs, the urgency can be reliably identified and grasped.

  According to the maintenance management system and the maintenance management apparatus 10 of the present embodiment, maintenance work for abnormalities and signs of failure occurring in each device provided in the weighing machines 20A1m to 20Anm installed in the respective gas stations A1 to An. When a maintenance work W with a high priority Y is generated with respect to W, in addition to notifying the occurrence, a maintenance work W with a low priority Y that has already been received and has not yet been actually performed is also automatically performed. Therefore, it is possible to prevent the maintenance work W having a low priority Y from being delayed and left unattended, and to improve the service for maintenance customers.

  The notification of the maintenance work W having a low priority Y for which the actual work has not yet been performed is not simply notified every time a new maintenance work W is received. Only when the priority Y is high, it is automatically notified along with the notification of its occurrence, so in the group such as the same gas station, the same location area, the same management line, the same meter type, etc. In relation to maintenance work W with high urgency and high priority Y, it is possible to actively carry out maintenance work W with low priority Y that has not yet been actually performed. It is possible to improve that the maintenance work W with a low degree Y is delayed and left behind.

  As described above, the maintenance management system and the maintenance management apparatus 10 of the present embodiment are configured, but the maintenance management system and the maintenance management apparatus of the present invention are not limited to the above-described embodiments.

  For example, in the determination condition R of the priority Y, the progress amount from the time when the previous maintenance work W is performed is acquired using the integrated amount Q as a parameter, but the number of refueling operations may be used as a parameter. Is possible.

  In addition, the unchecked list is configured to be displayed or printed out from the maintenance processing apparatus 11 of the maintenance management apparatus 10 in the maintenance company B, and is informed, for example, for each gas station, for each group of the same location, etc. In the case where the repair person is determined, the maintenance processing device 11 may send and output the data via a communication line 60 to the maintenance terminal device of the corresponding repair person via the communication line 60. .

Further, in the above-described embodiment, a maintenance request including abnormality information is generated by the gas station management terminal device 40 and transmitted from the gas station management terminal device 40 to the maintenance management device 10 of the maintenance company B via the communication line 60. configured as, but it is also possible to transmit the maintenance management apparatus 10 of the maintenance company B via a direct communication line 60 from the weighing machine 20 which is provided in the gas station a.

In addition, in the above-described embodiment, the maintenance work W and the priority thereof are also determined on the maintenance management apparatus 10 side that is the reception side of the maintenance request. However, the abnormality formed in the memory 35 of the weighing machine 20 and storage area of the recording area and the operation information, based on the data of the weighing machine such as a maintenance tube retainer Buru in the storage device 42 is stored in the gas station management terminal 40, the weighing machine 20 side or the service station management terminal 40 It is also possible to perform determination processing on the side. In this case, the maintenance request transmitted to the maintenance management apparatus 10 includes the maintenance work W corresponding to the abnormality information and the data of the priority Y.

  In the above-described embodiment, the fuel supply station that supplies gasoline, light oil, or the like has been described as an example of the fuel supply station. However, the maintenance management system and the maintenance management device of the present invention are charged with natural gas, hydrogen, and the like. The same effect can be obtained even when used in a filling station.

  In this case, the configuration of the fuel supply apparatus also changes when the type of fuel handled at the fuel supply station changes. For example, a CNG supply device that supplies compressed natural gas (CNG) compressed at a natural gas filling station to a fuel tank (filled tank) of a vehicle or the like is a natural gas whose pressure is increased to a predetermined pressure or higher (for example, 25 MPa) by a compressor. The gas is temporarily stored in the gas supply tank, and after the filling coupler provided at the end of the filling hose is coupled to the coupler of the tank to be filled, the natural gas stored in the gas supply tank is supplied to the tank to be filled and covered. The filling tank is filled until a predetermined pressure (for example, 20 MPa) is reached. Therefore, in the maintenance management system and the maintenance management device of the present invention, the configuration of the fuel supply device changes if the type of fuel handled at the fuel supply station changes, so the target device of the fuel supply device that detects an abnormal state, its abnormality information, The contents of the maintenance work and the like are not limited to the abnormality information and the contents of the maintenance work described in the above-described embodiment, and needless to say, the contents may be appropriately changed according to the fuel supply station and the fuel supply apparatus.
