Description

  The present invention relates to a fuel supply apparatus, and in particular, is configured to set information for identifying the nozzle in a nozzle having a display that displays a supply result (amount of supply) included in fuel supply information wirelessly transmitted to the nozzle. It is related with the made fuel supply apparatus.

  For example, in a liquid supply device (fuel supply device) installed at a liquid supply station or the like, remove the liquid supply nozzle provided at the tip of the liquid supply hose from the nozzle hook of the fuel supply machine and insert it into the liquid supply port of the vehicle. Supply liquid to the fuel tank (supplier). The nozzle switch of the fuel supply machine is equipped with a nozzle switch that detects that the liquid supply nozzle is locked, and the fuel supply control device activates the liquid supply pump by turning the nozzle switch on and off. Or stop control is performed.

  Then, the operator who performs the liquid supply operation operates the lever of the liquid supply nozzle in the valve opening direction to start supplying fuel to the fuel tank of the vehicle. When full liquid supply is performed, the liquid level detection mechanism of the liquid supply nozzle detects the liquid level, and the numerical display on the display has stopped indicating that the liquid supply has stopped due to the valve closing operation of the automatic valve closing mechanism. In addition, operate the lever of the liquid supply nozzle while observing the supply amount displayed on the indicator provided on the fuel supply machine so that the end of the supply amount displayed on the indicator becomes zero. In many cases, the adjustment operation is performed to match the numerical values.

  In recent years, with the spread of self-service liquid supply devices, there are an increasing number of cases where people who are not used to liquid supply operations perform liquid supply operations. Among them, the numerical value displayed on the display of the fuel supply machine In some cases, the liquid supply nozzle is automatically closed by the liquid level detection of the liquid level detection mechanism by operating the lever of the liquid supply nozzle while looking at the screen, and the adjustment operation is performed little by little.

  When performing such a fitting operation, the operator intermittently operates the nozzle lever so that the decimal point of the displayed numerical value becomes zero while looking at the indicator of the fuel supply machine. For this reason, the operator who performs the adjustment operation pays attention to the change in the value displayed on the indicator of the fuel supply machine, and does not look at the liquid supply port where the liquid supply nozzle is inserted. There was a risk of operating the nozzle lever without noticing that the fuel would overflow.

  As a means to prevent the fuel from overflowing from the liquid supply port when performing such nozzle operation, a display that displays the flow rate is provided on the liquid supply nozzle, so that the supply amount displayed on the display can be monitored. A liquid supply nozzle that can confirm the rise in the liquid level of the liquid mouth has been developed (see, for example, Patent Document 1).

Furthermore, it has been studied to adopt a configuration in which a cable is not provided in the fuel supply hose so that the flow rate measured by the flow meter housed in the fuel supply machine can be transmitted and received wirelessly to the indicator of the liquid supply nozzle. Thus, when the flow rate value measured by the flow meter of the fuel supply machine is wirelessly transmitted to the indicator of the liquid supply nozzle, for example, a plurality of liquid supply nozzles are provided in the same fuel supply machine. ID information (specific information) for nozzle identification is set in advance for each liquid supply nozzle, and ID information included in a wireless signal transmitted from the antenna of the fuel supply machine is set in the display of the liquid supply nozzle. When it matches, the liquid supply information transmitted together with the ID information can be read and the flow rate can be displayed on the display of the liquid supply nozzle.
Japanese Patent Laid-Open No. 10-167397

  Since different ID information is set in advance for each of the plurality of liquid supply nozzle indicators as described above, for example, the liquid supply nozzle display used at the liquid supply station has failed and is new. When exchanging, ID information registered in the control unit of the fuel supply machine is set as ID information corresponding to the indicator of the liquid supply nozzle at the site.

  For this reason, when the display or liquid supply nozzle is replaced with a new one, a maintenance terminal device is connected to the control unit of the fuel supply machine via a connection cable, and the keys of the terminal device are operated to manually supply the fuel. The liquid nozzle ID information is set and operated.

  In this case, since the number of keys to be operated increases, it is not possible to input ID information correctly due to an operation error, or it takes time to set ID information as a result by performing the input operation again. The problem arises.

  Although a method of inputting ID information of an arbitrary liquid supply nozzle to a plurality of liquid supply nozzles using a wireless remote controller is conceivable, the liquid supply nozzle for which no ID information is set is specified in the first place. Therefore, the ID information cannot be directly input to the display unit of the liquid supply nozzle by radio.

  As another method, a method of preparing a plurality of liquid supply nozzles set with the same ID information as a plurality of liquid supply nozzles of the fuel supply machine is also conceivable, but the same number of liquid supply nozzles as the ID information is prepared. It will be so unrealistic.

  In view of the above circumstances, an object of the present invention is to provide a fuel supply device that solves the above-described problems.

  In order to solve the above problems, the present invention has the following means.

The setting instruction transmitting means is a display corresponding to the nozzle when the nozzle placement detecting means has not detected the nozzle when the power switch of the fuel supply machine is operated from OFF to ON. The above problem is solved by instructing the display to set the specific information of the display.

  According to the present invention, when specific information setting instructions are given by the setting instruction means, the specific information setting means uses the specific information received by the receiving means as the specific information of the display, so that the nozzle display Even when the device or the nozzle is replaced, the specific information corresponding to the nozzle can be easily set in the display device, and the supply result can be accurately displayed on the display device that should display the supply result. .

  Further, according to the present invention, since the setting instruction means of the indicator operates based on the setting instruction of the specific information transmitted from the setting instruction transmission means of the fuel supply machine, the identification corresponding to the nozzle transmitted from the fuel supply machine Information can be easily set as specific information of the display of the nozzle.

Here, data transmitted from the wireless transmitter 92 of the fuel supply unit 24 when the liquid supply is started will be described. FIG. 8 is a diagram showing a message format of liquid supply data transmitted from the wireless transmitter 92 to the nozzle display units 90A to 90F. As shown in FIG. 8, the liquid supply data (fuel supply information) 200 transmitted from the wireless transmitter 92 includes a code “STX” indicating the start of a message, a code “1” indicating an ID (specific information), Numerical data representing the supply amount (supply record), “ETX” representing the end of the message, and code “0x06” representing BCC (block check character) for performing bit error detection by parity check for confirming an electronic error And have.
The code “00” representing the display method represents, for example, a display method for displaying characters and numerical values in a normal size, and “01” represents, for example, a display method for displaying characters and numerical values about twice as large as usual. To express. The control unit 130 of the liquid supply nozzle 30 that has received this message displays the current supply amount with a numerical value instructed by the nozzle display 96.

  Therefore, the control circuit 36 of the fuel supply unit 24 that supplies liquid transmits the supply amount together with the ID code from the wireless transmitter 92 to the nozzle display units 90A to 90F. In the nozzle display units 90A to 90F, an ID code for each nozzle is set in advance, and the set supply amount of the ID code is received and displayed. In addition, although the liquid supply data 200 has been exemplified for the case where numerical data representing the supply amount is included, the amount of supply according to the supply amount may be included as the supply result together with the supply amount.

  FIG. 9 is a diagram showing an example of an ID code corresponding to the type of nozzle. As shown in FIG. 9, for example, the ID of the nozzle that supplies regular gasoline on the front side (A side) of the fuel supply machine 24 is “1”, and the ID of the nozzle that supplies high-octane gasoline is “2”. The ID of the nozzle that supplies light oil is set to “3”. In addition, the ID of the nozzle that supplies regular gasoline on the back side (B side) of the fuel supply unit 24 is “4”, the ID of the nozzle that supplies high-octane gasoline is “5”, and the ID of the nozzle that supplies light oil. Is set to “6”. Further, the ID when the ID is not set in the shipping state is “0”. The ID code may be a number as described above, or a combination of a number and an alphabet.

  As shown in FIG. 10 (A), the control circuit 36 of the fuel supply machine 24 uses the supply amount (and / or the amount corresponding to the supply amount) obtained by integrating the flow rate measurement values by the supply liquid as the supply result and the ID code ( A telegram 210 having the following information is transmitted wirelessly. The electronic message 210 is data in which the plurality of liquid supply data 200 described above are arranged in time series. When the ID codes of the nozzle display units 90A to 90F are “0”, the control circuit 36 of the fuel supply unit 24 changes the ID code from “0” to the setting ID corresponding to the liquid supply nozzle from “1 to 6”. In order to set to any of these, the message | telegram 220 which has setting ID (refer FIG. 9) is transmitted by radio | wireless. 10A and 10B are shown in a simplified manner for convenience of explanation, but actually have a data structure as shown in FIG.

  FIG. 11 is a flowchart for explaining a liquid supply control process executed by the control circuit 36 of the fuel supplier 24. In FIG. 11, the control circuit 36 checks whether or not the nozzle hooking switch 50 is OFF in S11. When the operator performs the liquid supply operation, when the liquid supply nozzle 30A corresponding to the oil type (for example, regular gasoline) to be supplied is lifted from the nozzle hook 23A, the nozzle hook switch 50A is turned off. Accordingly, when the nozzle hooking switch 50A is turned off in S11, the process proceeds to S12 and the liquid supply pump 40A is activated. At the same time, in S13, the display of the flow rate display 27A and the display 94 of the liquid supply nozzle 30A is reset to zero.

  In the next S14, it is checked whether or not a flow rate pulse is output from the flow meter 42. When the operator operates the nozzle lever 30d of the liquid supply nozzle 30A in the valve opening direction to start liquid supply, the flow meter 42A outputs a flow rate pulse having a period proportional to the flow rate of the liquid supply. Therefore, if a flow rate pulse is output in S14 (in the case of YES), the integrated flow rate is calculated by integrating the flow rate pulse in S15.

  Then, it progresses to S16 and displays the present integrated flow on the flow indicator 27 of the weighing machine 24. At the same time, in S <b> 17, the liquid supply data 200 with the display code “00 (normal size)” is transmitted from the wireless transmitter 92 to the control unit 130 of the liquid supply nozzle 30. Thereby, as shown in FIG. 4A, the control unit 130 of the liquid supply nozzle 30 supplies the nozzle indicator 96 with a normal size number (the supply amount and / or the amount corresponding to the supply amount). ) Is displayed. Therefore, the operator can simultaneously see the nozzle display unit 90A of the liquid supply nozzle 30A and the liquid supply port into which the discharge pipe 30a is inserted while performing the liquid supply operation. It becomes possible to be careful.

  In next S18, it is checked whether or not the fuel flow velocity is zero based on the presence or absence of a flow rate pulse. When it is determined in S18 that the flow velocity has become zero (in the case of YES), the process proceeds to S19 and it is determined that the automatic valve closing mechanism of the liquid supply nozzle 30 has been closed by detecting the liquid level.

  Therefore, in S20, the ID code “1” and the supply amount data are transmitted from the wireless transmitter 92 to the control unit 130 of the liquid supply nozzle 30A as shown in FIG. Thereby, the control unit 130 of the liquid supply nozzle 30 </ b> A corresponding to the ID code “1” displays the integrated flow rate (supply amount) on the nozzle display 96.

  In the next S21, it is checked whether or not the nozzle hooking switch 50A of the nozzle hooking A32 has been turned on. In S21, when the nozzle hooking switch 50A of the nozzle hooking 32A is OFF, since the liquid is being supplied, the process returns to S20. Further, when the operator finishes the liquid supply and returns the liquid supply nozzle 30A to the nozzle hook 32A, the nozzle hook switch 50A is turned on. Therefore, when the nozzle hooking switch 50A of the nozzle hooking 32A is turned on in S21, the process proceeds to S22 and the liquid supply pump 40A is stopped. This completes a series of control processes.

  FIG. 12 is a flowchart for explaining a control process executed by the control unit 130 of the nozzle display units 90A to 90F. In FIG. 12, the control unit 130 of the nozzle display unit 90 checks whether or not the liquid supply data 200 (see FIG. 8) transmitted from the weighing machine 24 side in S31 is received via the wireless receiver 140. When the liquid supply data 200 is received in S31 (in the case of YES), the process proceeds to S32 and the liquid supply data 200 is read.

  In next step S33, it is checked whether or not the ID code included in the liquid supply data 200 matches a preset ID code. In S33, when the ID codes do not match (in the case of NO), since it is not the liquid supply data for the liquid supply nozzle, the process returns to S31 and the processes after S31 are performed. In S33, when the ID codes match (in the case of YES), the process proceeds to S34 to check whether the supply amount (supply result) included in the liquid supply data (fuel supply information) 200 is greater than zero. To do.

  If the supply amount included in the liquid supply data 200 is greater than zero (YES) in S34, the process proceeds to S35, and the received supply amount is displayed on the nozzle display 96. In S34, when the supply amount included in the liquid supply data 200 is zero (in the case of NO), the process of S35 is omitted.

  In S36, it is checked whether or not the current liquid supply operation is completed. If the liquid supply end data is not transmitted from the fuel supply unit 24 in S36, the process returns to S34, and the processes after S34 are performed. In S36, when the nozzle switch 50 of the nozzle hook 32A corresponding to the liquid supply nozzle 30A is turned on and the liquid supply end data is transmitted from the fuel supply machine 24 side, the process proceeds to S37, and the nozzle indicator The display of 96 is turned off.

  Next, when setting the ID code (see FIG. 9) in the control unit 130 of the nozzle display units 90A to 90F provided in the liquid supply nozzles 30A to 30F using the liquid supply data transmitted from the fuel supply unit 24. Next, the control process 1 executed by the control circuit 36 will be described with reference to FIG.

  The control circuit 36 checks whether or not the power switch 80 of the fuel supply machine 24 is turned on in S41 of FIG. When the power switch 80 of the fuel supply device 24 is turned on, the process proceeds to S42, and it is checked whether or not one of the liquid supply nozzles 30A to 30F is removed from the nozzle hooks 23A to 32F. That is, when any one of the nozzle hooking switches 50A to 50F is off (in the case of YES), the process proceeds to S43, and the control process of the display ID setting mode is started.

  Subsequently, in S44, for example, a setting message (for example, see FIG. 10A or FIG. 10B) in which the ID code “1” of the liquid supply nozzle 30A corresponding to the nozzle switch 50A that has been turned off is set is transmitted wirelessly (see, for example, FIG. Setting instruction means). Thereby, the nozzle display unit 90 of one liquid supply nozzle which received the setting message among the liquid supply nozzles 30A to 30F registers the ID code included in the received setting message as the setting ID of the liquid supply nozzle. Subsequently, in S45, it is checked whether or not the power switch 80 is turned off. In S45, when the power switch 80 is turned on (in the case of YES), the process in S44 is repeated, and when the power switch 80 is turned off (in the case of NO), the current ID setting process is terminated.

  In S42, when the liquid supply nozzles 30A to 30F are not removed from the nozzle hooks 23A to 32F (in the case of NO), the process proceeds to S46, and the normal liquid supply mode (control process in FIG. 11) is performed. Do.

  Accordingly, when the nozzle display unit 90A of one liquid supply nozzle 30A out of the liquid supply nozzles 30A to 30F fails and is replaced with a new one, the liquid supply nozzle 30A with the replaced nozzle display unit 90A is removed from the nozzle hook 23A. By turning on the power switch 80 of the fuel supplier 24 in this state, the ID code corresponding to the liquid supply nozzle 30A can be easily set in the nozzle display unit 90A. In addition, the other liquid supply nozzles 30B to 30F that are hung on the nozzle hooks 23B to 32F include the ID codes corresponding to the other liquid supply nozzles 30B to 30F because the nozzle hooking switches 50B to 50F are on. Data is not sent. For this reason, according to the setting method of the present embodiment, the ID code is accurately set, and other ID codes are prevented from being set by mistake.

  For example, in response to a sudden failure of the liquid supply nozzle 30, for example, the liquid supply nozzle 30 used in another fuel supply machine is temporarily moved to cause a failure in the fuel supply machine 24. May be used in exchange for. Therefore, a new ID code (see FIG. 9) is set in the control unit 130 of the nozzle display units 90A to 90F provided in the liquid supply nozzles 30A to 30F, and the liquid supply nozzle 30 removed from other fuel supply machines is set. The control process 2 executed by the control circuit 36 when used temporarily will be described with reference to FIG.

  When the power switch 80 of the fuel supply machine 24 is turned on in S51 of FIG. 14, the control circuit 36 proceeds to S52 and checks whether any one of the nozzle hooking switches 50A to 50F is off. In S52, when any one of the nozzle hooking switches 50A to 50F is off (in the case of YES), the process proceeds to S53, and the control process of the new ID setting mode is started. Accordingly, as in the case of the first embodiment, for example, by turning on the power switch 80 of the fuel supplier 24 with the liquid supply nozzle 30A removed from the nozzle hook 23A, the liquid supply nozzle 30A can be easily handled. The ID code to be set can be set in the nozzle display unit 90A.

  Subsequently, in S54, for example, a setting message (for example, refer to FIG. 10A or FIG. 10B) in which the ID code “1” of the liquid supply nozzle 30A corresponding to the nozzle switch 50A turned off is set is transmitted wirelessly. Accordingly, the nozzle display unit 90 of the liquid supply nozzle 30A that has received the setting message registers the ID code included in the received setting message as the setting ID of the liquid supply nozzle. In S55, it is checked whether the power switch 80 is turned off. In S55, when the power switch 80 is off (in the case of YES), the current setting mode is terminated.

  In S55, when the power switch 80 is on (in the case of NO), it is a case where the set ID is to be changed, and the process proceeds to S56, where any one of the other nozzle hooking switches 50B to 50F is off. Check whether or not.

  In S56, when any one of the nozzle hooking switches 50B to 50F is off (in the case of YES), the process proceeds to S57 and shifts to the ID change mode. Subsequently, in S58, the ID change message 230 shown in FIG. 15 is wirelessly transmitted. The ID change message 230 includes the IDs of the liquid supply nozzles 30A to 30F, such as the ID of the liquid supply nozzle removed first, the ID of the liquid supply nozzle removed next, and so on. As a result, the nozzle display unit 90A of the liquid supply nozzle 30A removed first sets the new ID code included in the received ID change message 230 as the setting ID of the liquid supply nozzle 30A. Note that the electronic message 230 of FIG. 15 is shown in a simplified manner for convenience of explanation, but actually has a data configuration as shown in FIG.

  In S56, when all of the nozzle hooking switches 50B to 50F are on, the liquid supply nozzles 30B to 30F are not removed, so the process returns to S54 and repeats S54 to S56.

  In S59, when the power switch 80 is turned off (in the case of NO), the current ID changing process is terminated.

  In S52, when the liquid supply nozzles 30A to 30F are not removed from the nozzle hooks 23A to 32F (in the case of NO), the process proceeds to S60 and the normal liquid supply mode (control process in FIG. 11) is performed. Do.

  Accordingly, when the nozzle display unit 90A of one of the liquid supply nozzles 30A to 30F breaks down and the liquid supply nozzle 30 being used in another fuel supply unit 24 is temporarily used, the liquid supply nozzle Since the 30 nozzle display units 90 have already been set with an ID code, the ID code can be changed to an ID code corresponding to the fuel supply unit 24. As a result, when the new liquid supply nozzle 30 is not in time, the liquid supply nozzle 30 removed from the other fuel supply machine 24 can be used temporarily instead of the failed liquid supply nozzle.

  FIG. 16 is a flowchart for explaining the control process 2 executed by the control unit 130 of the nozzle display unit 90 when the ID of the liquid supply nozzle 30 is zero. As shown in FIG. 16, the control unit 130 of the nozzle display unit 90 checks in S <b> 71 whether or not a message 220 (see FIG. 10B) addressed to ID = 0 is received. In S71, when the message 220 addressed to ID = 0 is transmitted from the fuel supply unit 24 and this message 220 is received (in the case of YES), the process proceeds to S72, and the ID of the nozzle is changed (set) to the ID of the message 220. (Specific information setting means) Thus, the ID = 0 of the nozzle is changed to ID = 1, for example.

  In S71, when a message other than ID = 0 is received (in the case of NO), the process proceeds to S73, where it is checked whether the message is addressed to the ID of the nozzle. When the electronic message 210 (see FIG. 10A) addressed to the ID of the nozzle is received in S73 (in the case of YES), the process proceeds to S74, and the supply amount (supply result) included in the electronic message 210 is displayed on the nozzle display 96. To do. If the electronic message 210 addressed to an ID other than the nozzle ID is received in S73 (in the case of NO), the process of S74 is not performed.

  In S75, it is checked whether or not the power switch 80 of the fuel supply unit 24 is off. When the power switch 80 is on, the telegrams 210 and 220 are transmitted, so the process returns to S71, and after S71. Execute the process again. However, when the power switch 80 of the fuel supply machine 24 is turned off in S75, the electronic message is not transmitted, so the current process is terminated.

  As described above, in the case of ID = 0, the nozzle display unit 90 receives the message 220 and changes (sets) the ID to the ID of the nozzle, and then receives and supplies the message 210 addressed to the set ID. The amount can be displayed on the nozzle display 96.

  FIG. 17 is a flowchart for explaining the control process 3 executed by the control unit 130 of the nozzle display unit 90 when the ID of the liquid supply nozzle 30 is zero. As shown in FIG. 17, the control unit 130 of the nozzle display unit 90 checks in S <b> 81 whether or not a message 220 (see FIG. 10B) addressed to ID = 0 is received. In S81, when a message 220 addressed to ID = 0 is transmitted from the fuel supply unit 24 and this message 220 is received (in the case of YES), the process proceeds to S82, and the ID of the nozzle is changed (set) to the ID of the message 220. (Specific information setting means) Thus, the ID = 0 of the nozzle is changed to ID = 1, for example.

  In S81, when a message other than ID = 0 is received (in the case of NO), the process proceeds to S83 to check whether the message is addressed to the ID of the nozzle. When the electronic message 210 (see FIG. 10A) addressed to the nozzle ID is received in S83 (in the case of YES), the process proceeds to S84, and whether or not the received electronic message contains liquid supply information (supply results). Check. In S84, when liquid supply information is included in the received electronic message (in the case of YES), the process proceeds to S85, and the supply amount included in the liquid supply information of the electronic message 210 is displayed on the nozzle display 96. If the message received in S84 is the message 230 that does not include the liquid supply information (NO), the process proceeds to S86, and the ID of the nozzle is changed (set) to the ID of the message 230. Thus, the ID of the nozzle is changed (set) to ID = 1, for example.

  In S87, it is checked whether or not the power switch 80 of the fuel supply unit 24 is off. When the power switch 80 is on, the telegrams 210 and 220 are transmitted, so the process returns to S81, and after S81. Execute the process again. However, when the power switch 80 of the fuel supply machine 24 is turned off in S87, a message is not transmitted, and the current process is terminated.

  As described above, in the case of ID = 0, the nozzle display unit 90 receives the message 220 and changes (sets) the ID to the ID of the nozzle, and then receives and supplies the message 210 addressed to the set ID. The amount can be displayed on the nozzle display 96. Further, when the nozzle display unit 90A of the liquid supply nozzle 30A breaks down due to S86 and the liquid supply nozzle 30 being used in another fuel supply unit 24 is temporarily used, the nozzle display unit 90 of the liquid supply nozzle 30 is displayed. Since an ID code has already been set, the ID code can be changed to an ID code corresponding to the fuel supply unit 24.

  FIG. 18 is a flowchart for explaining the control process 4 executed by the control unit 130 of the nozzle display unit 90 in accordance with the on / off of the mode changeover switch 95 of the liquid supply nozzle 30. As shown in FIG. 18, the control unit 130 of the nozzle display unit 90 checks whether or not the mode switch 95 is on in S91. In S91, when the mode switch 95 is ON (in the case of YES), the process proceeds to S92, and the ID of the nozzle is set to the ID of the received message 210 (see FIG. 10A) (specific information setting means). Thus, the ID of the nozzle is set to ID = 1, for example.

  In S91, if the mode switch 95 is OFF (NO), the process proceeds to S93, where it is checked whether a message addressed to the ID of the nozzle has been received. When the electronic message 210 addressed to the nozzle ID is received in S93 (in the case of YES), the process proceeds to S94, and the liquid supply information (supply record) included in the electronic message 210 is displayed on the nozzle display 96. If the message received in S93 is not addressed to the ID of the nozzle (in the case of NO), the process of S94 is performed.

  In S95, it is checked whether or not the power switch 80 of the fuel supply unit 24 is off. When the power switch 80 is on, there is a transmission of a telegram 210, so the process returns to S91, and the processes after S91 are performed. Run again. However, when the power switch 80 of the fuel supply machine 24 is turned off in S95, the electronic message is not transmitted, and thus the current process is terminated.

  Thus, in the nozzle display unit 90, when the mode changeover switch 95 is on, the ID of the received electronic message 210 is set to the ID of the nozzle, and then the liquid supply information (supply) of the electronic message 210 addressed to the set ID is supplied. Result) can be displayed on the nozzle display 96.

  FIG. 19 is a flowchart for explaining the control process 5 executed by the control unit 130 of the nozzle display unit 90 in accordance with ON / OFF of the mode changeover switch 95 of the liquid supply nozzle 30. As shown in FIG. 19, the control unit 130 of the nozzle display unit 90 checks whether or not the mode switch 95 is on in S101. In S101, if the mode switch 95 is ON (YES), the process proceeds to S102, and the ID of the nozzle is set to the ID of the received message 210 (see FIG. 10A) (specific information setting means). Thus, the ID of the nozzle is set to ID = 1, for example.

  In S101, if the mode switch 95 is OFF (NO), the process proceeds to S103, and it is checked whether or not a message addressed to the ID of the nozzle has been received. When the electronic message 210 addressed to the nozzle ID is received in S103 (YES), the process proceeds to S104, and the liquid supply information (supply record) included in the electronic message 210 is displayed on the nozzle display 96. If the message received in S103 is not addressed to the ID of the nozzle (in the case of NO), the process proceeds to S105, and if the received message is ID = 99 (in addition to ID = 99, any other number is not used) Check whether it is addressed.

  In S105, when the received electronic message is addressed to ID = 99 (in the case of YES), the process proceeds to S106, and the nozzle ID is displayed on the nozzle display 96. In S105, if the received message is not addressed to ID = 99 (in the case of NO), the process of S106 is not performed.

  Then, in S107, it is checked whether or not the power switch 80 of the fuel supply machine 24 is off. When the power switch 80 is on, there is transmission of the telegram 210, so the process returns to S101, and the processing after S101 Run again. However, when the power switch 80 of the fuel supply machine 24 is turned off in S107, the electronic message is not transmitted, and thus the current process is terminated.

  Thus, in the nozzle display unit 90, when the mode changeover switch 95 is on, the ID of the received electronic message 210 is set to the ID of the nozzle, and then the liquid supply information (supply) of the electronic message 210 addressed to the set ID is supplied. Result) can be displayed on the nozzle display 96. Further, when the received message is addressed to ID = 99, the ID set by the nozzle display units 90A to 90F of the liquid supply nozzles 30A to 30F is displayed, so that the maintenance worker can identify the ID of the liquid supply nozzles 30A to 30F. Can be easily confirmed, and it can be determined whether there is a setting error in the ID setting.
