Description

[Detailed description of the invention]

The present invention relates to a refueling method suitable for application to, for example, a self-service refueling device. In general, self-service refueling devices are not operated by full-time workers at a gas station, but are operated individually by a car driver or the like. As described above, since this type of refueling device is intended to be operated by an amateur, it is necessary to ensure that the refueling operation is guided reliably and to ensure that there are no errors in the operating procedure. Therefore, the self-service refueling device according to the prior art is equipped with a refueling guide device in which subtitles for refueling guidance are rotatably attached to the front panel of the weighing machine.
There is a known system in which subtitles for refueling guidance are sequentially rotated prior to the refueling operation to notify the operating procedure in advance. However, in reality, with such a display system, even if the operating procedure is notified in advance, it is not possible to perform a complicated refueling operation reliably without making any mistakes. There are also known systems in which a speaker is installed near the refueling device and operating procedures are announced using a cassette tape, or a supervisor in the refueling station office speaks out the operating procedures while looking at the refueling device. However, when using a cassette tape, it is very difficult to perform the refueling operation according to the instructions even if the operator listens to the instructions in advance, as in the case of subtitles for refueling guidance mentioned above. Although the method of giving instructions can ensure safety, it has the disadvantage that it is more time-consuming and goes against the trend of self-service. The present invention was made in view of the drawbacks of the conventional method described above, and it detects the refueling operation status of a weighing machine, and based on the detection result, the operating procedure is displayed on a graphic display, or the display and audio It is an object of the present invention to provide a refueling system in which an operator is notified of each situation sequentially by using a voice-producing device. In order to achieve the above object, the first invention of this application provides a measuring machine that performs oil supply from a refueling nozzle provided at the tip of a hose via a pump and a flow meter;
a detector for detecting the operating state of the weighing machine; an alarm for guiding the next operation according to each operating state of the weighing machine; a determining means for determining whether the operation of the weighing machine is a normal operation instructed in advance or an erroneous operation each time a detection result is input; If the operation is a pre-instructed normal operation, instruct the next predetermined normal operation for the operating state of the weighing machine, and if the operation of the weighing machine is a pre-instructed erroneous operation. an operation instruction means for instructing a predetermined return operation for an erroneous operation state of the weighing machine in order to return the weighing machine to a predetermined normal operating state before the operating state;
and drive control means for driving and controlling the annunciator so that the annunciator guides the next operation in response to an instruction input from the operation instructing means. With this configuration, the determining means determines whether the operation of the weighing machine is a normal operation instructed in advance or an erroneous operation, each time a detection result corresponding to the operating state of the weighing machine is input from the detector. Based on the determination result input from the determining means, the operation instruction means instructs the drive control means to carry out the next normal operation if the operation is a normal operation, and instructs the drive control means to carry out a predetermined normal operation if the operation is an error. Instructs the return operation to return to. Thereby, the drive control means causes the alarm to guide the next operation in response to the instruction inputted from the operation instruction means, so that the operation of the weighing machine always proceeds in a correct manner.

Under the control of 28, the guide display drive circuit 35 displays these figures and characters as each form shown in A to P in FIG.
0j is configured to flicker as necessary. The oil supply device used in the present invention is constructed as described above, and its basic operation will be explained based on the operation explanatory diagram of FIG. 5. First, a car enters the refueling area, the vehicle sensor 20 detects this and outputs a vehicle entry signal,
Alternatively, when a card is inserted into the card reader 22 of the reader printer 21 and a card reading signal is output, and a weighing machine designation signal is output from the weighing machine designation switch 23, each of these signals is input to the CPU 28 as an interlock release signal. , weighing machine 1
The interlock is released (step 1). If the current refueling operation is preset refueling, the preset switch 11 is operated (step 2), and in step 3 a desired preset value is set and stored in the RAM 29. If the refueling nozzle 15 is removed from the nozzle housing 18 immediately after setting the preset value in the case of preset refueling, or immediately after the interlock is canceled in step 1 in the case of normal refueling, the nozzle switch 19 will close. A refueling preparation state including resetting the counter 9 is entered (step 4), and then when the refueling nozzle 15 is inserted into the fuel tank of the vehicle, the insertion sensor 16 is closed (step 5).
As a result, the CPU 28 detects the closing of the nozzle switch 19 and the insertion sensor 16, outputs a motor drive signal from the output I/F 33 to the motor drive control circuit 38, and starts the motor 5 (step 6). As a result, when the oil supply nozzle 15 is opened and the nozzle is operated (step 7), the oil in the underground tank is supplied from the oil supply nozzle 15 via the pipe 4, pump 6, flow meter 7, and hose 14. The amount of oil supplied every moment at this time is measured by the flow meter 7, and the flow rate is stored in the RAM 29 as a pulse signal from the flow transmitter 8, and counted by the CPU 28. Next, the CPU 28 determines whether the tank is full or not based on the presence or absence of a full tank signal from the liquid level sensor 17 in step 8. If the full tank signal is output now, a motor stop signal is output to the motor drive control circuit 38 to stop the motor 5, regardless of preset lubrication or normal lubrication. As a result, even if the refueling nozzle 15 remains open, the outflow of oil is stopped, so when the refueling nozzle 15 is closed, removed from the fuel tank, and hung in the nozzle housing 18, the nozzle switch 19 is turned on. is opened (step 10), and weighing machine 1 is opened in step 11.
is interlocked again and the series of refueling processes is completed. On the other hand, if it is determined in step 8 that the full tank signal is not output, then in the next step 12 it is determined whether preset refueling or normal refueling is to be performed.
For normal refueling, the insertion sensor 16 is opened by closing the refueling nozzle 15 and removing it from the fuel tank (step 13), and the motor 5 is stopped by outputting a motor stop signal from the CPU 28. (Step 14). At this time, when the refueling nozzle 15 is reinserted into the fuel tank for additional refueling, the insertion sensor 16 is closed again, so the CPU 28 monitors the re-insertion of the insertion sensor 16 in step 15. When the insertion sensor 16 closes again, it is determined that additional oil supply is to be performed, and the process returns to step 6, where the motor 5 is restarted and the aforementioned processes are repeated. When it is determined in step 15 that the insertion sensor 16 remains open, the refueling nozzle 15 is hooked to the nozzle housing 18, and the nozzle switch 19 is opened (step 16), the weighing machine 1 is interlocked in step 11, and the series The refueling operation is completed. Furthermore, if preset lubrication is determined in step 12, the CPU 28 compares the preset amount stored in the RAM 29 with the actual lubrication amount, and outputs a quantitative signal to the motor drive control circuit 38 when the actual lubrication amount reaches the preset amount. Then, the motor 5 is stopped (step 17). Then, in step 18, the refueling nozzle 15
Insert sensor 1 by removing it from the fuel tank.
6 is opened, and if it is opened, the process goes to step 15, and the presence or absence of the above-mentioned additional oil supply is monitored. The above is the basic operation of the refueling device used in the present invention.Next, the guidance display operation and voice production operation according to the refueling system of the present invention will be described in addition to the basic operation shown in FIG. 5 described above. First, the case of normal refueling will be described according to the flowcharts shown in FIGS. 6A and 6B. In Figure 6 A and Figure 6 B, capital letters A, B, C,...
O, P represent each form A, B, C...O, P of the guide display 10 shown in FIG. 4, and lowercase letters a, b, c,...k, in FIGS. l represents the uttered audio phrase shown in Table 1 below.

【table】

[Table] However, in Figures 6A and 6B, step 1 is expressed as "S1", and in the same way, steps are expressed as "S2".
As shown in step S1, before the vehicle reaches the refueling area,
As shown by "A" on the guide display 10, the refueling nozzle 15 is at position 10c, and the characters "STANDBY" indicating standby are displayed, and the weighing machine 1 is in a standby state. Here, when the vehicle reaches the refueling area and stops near one of the plurality of weighing machines 1, the corresponding vehicle sensor 20 closes (step S2). As a result, CPU 28 uses RAM 2
9 and activates the guide display drive circuit 35 to display the form shown in "B", and displays the characters "START" on the guide display 10 like "B" to guide the start of the operation ( Step S3). At the same time, the CPU 28 accesses the voice phrases stored in the ROM 30, outputs the voice phrases corresponding to "a" in Table 1 to the voice synthesis circuit 36, and sends them to the speaker 12 via the amplifier 37. Sorry. We will inform you of the operation method by voice and guidance display. Please read your ping pong card into the card reader and specify the weighing machine number ○○."
utter a voice (step S4). Next, the CPU 28 reads the card reader 22 (or the card reader of the POS 26) in step S5.
It is determined whether a card is inserted into the card and a card reading signal is input. First, when the card reading signal is not input, the refueling nozzle 1
5 is removed and the nozzle switch 19 is closed (step S6). If the nozzle switch 19 remains open, the soft timer 31 determines whether or not the nozzle switch 19 is closed after the vehicle sensor 20 is closed. When 30 seconds have elapsed, it is determined that the vehicle has just passed through the refueling area, and the process returns to step S1, where it is placed in a standby state again (step S7). On the other hand, when the refueling nozzle 15 is removed and the nozzle switch 19 is closed in step S6, the CPU 28 detects the closing of the nozzle switch 19 and displays the shape of "C" on the guide display 10. Turn the arrow 10 until the refueling nozzle 15 is hung in the nozzle storage part 18.
g flickers to call attention (step
S8). At the same time, the CPU 28 outputs the voice phrase "b" in Table 1 to the voice synthesis circuit 36, and causes the speaker 12 to utter the voice "Please read the card before removing the nozzle." S9). Then, when the nozzle switch 19 is closed by applying the refueling nozzle 5 (step S10), the mode "B" is displayed on the guide display 10 again (step S11), and the process returns to step S5 before reading the card. . Next, in step S5, the card reader 2
If the card is read in step S12, the weighing machine designation switch 23 is operated to determine whether the weighing machine 1 at the location where the vehicle has stopped has been designated. At this time, if the weighing machine designation switch 23 is not operated in step S13 and the nozzle switch 19 remains open, if 30 seconds have elapsed since the vehicle sensor 20 was closed in step S14, Although the vehicle has passed through the refueling area, it is determined that the card has been inserted into the card reader 22 to sell other products such as oil change and air supply, and the process returns to step S1.
On the other hand, when the refueling nozzle 15 is removed and the nozzle switch 19 is closed in step S13, the CPU 2
8 detects the card reading signal and the input of the nozzle switch 19, displays the configuration "C" on the guide display 10, and guides the refueling nozzle 15 to be hung in the nozzle housing 18 (step S15). At this time, the arrow 10g is flickered until the refueling nozzle 15 is returned. Nozzle switch 19 by refueling nozzle 15
is opened (step S16), the CPU 28 displays form "B" again and returns to step S12. Next, in step S12, when the weighing machine designation switch 23 is closed and the weighing machine 1 is designated, the modes "B" and "D" are alternately flickered in step S18, and the refueling nozzle 15 is moved to the nozzle housing. 18 and guide it to be inserted into the fuel tank of the automobile 10b (step S18).
At the same time, a voice such as "c" in Table 1, "Please remove the ping pong nozzle and set the nozzle to the fuel filler port of the vehicle" is uttered (step S19). If the nozzle switch 19 does not close despite the display and audio guidance in steps S18 and S19 described above (step S20), turn off the weighing machine designation switch 23 30 seconds after reading the card. It is determined that the operation has been performed, and the process returns to step S1 (step S21). On the other hand, when the refueling nozzle 15 is removed and the nozzle switch 19 is closed in step S20, the CPU 28 causes the guide display 10 to alternately flicker the formats "D" and "E" (step S22), and connects the refueling nozzle 15 to the fuel tank. prompt you to insert it. As a result, in the next step S23, the CPU 28 determines whether or not the insertion sensor 16 has been closed due to the insertion of the refueling nozzle 15. First, step
Even though the configurations "D" and "E" are flickered in S22, if the insertion sensor 16 remains open and the nozzle switch 19 is opened (step S24), the refueling nozzle 15 is not inserted into the fuel tank. In step S25, it is determined that the refueling operation has been stopped, and in the next step S25, it is determined whether the displayed value of the counter 9 is zero or not.If the displayed value is zero, it is determined that the refueling operation has been stopped. Then step S1
Return to On the other hand, as will be described later, if the displayed value is not zero in step S25, it is determined in the next step S52 whether or not the tank is fully refueled. By the way, when the insertion sensor 16 is closed in step S23, it is determined that the refueling nozzle has been inserted into the fuel tank, and in the next step S26, the CPU
28 displays a form "F" including the characters "OPEN" on the guide display 10 to urge the fuel nozzle 15 to open. At the same time, the speaker 12 emits a voice saying, "Please hold the ping pong nozzle lever and refuel until the desired amount is reached."
S27). Next, based on the above-mentioned guidance, the CPU 28 determines whether a pulse signal has been transmitted from the flow rate transmitter 8 (step S28). However, the fact that there is no pulse signal input in step 28 means that
Since the valve opening operation of the refueling nozzle 15 has not been performed, if no pulse signal is input, it is determined in the next step S29 whether or not the insertion sensor 16 is opened. When the insertion sensor 16 is opened, in the next step S30, the guide display 10 flickers the formats "D" and "E" again to ensure that the fuel nozzle 15 is inserted into the fuel tank again. At the same time, in step S31, a voice saying ``The nozzle is not set in the refueling port'' is uttered, and the process returns to step S24 to continue monitoring whether or not the refueling nozzle 15 has been inserted. If the nozzle switch 19 is opened in step S24, since refueling is not being performed at this time, the process returns from step S25 to the initial state of step S1. On the other hand, when a pulse signal is transmitted from the flow rate transmitter 8 in the aforementioned step S28, it is determined that the refueling nozzle 15 has opened, and the process moves to the next step S32, where the CPU 28 stores the RAM 29 or ROM 30 in the arithmetic unit 28. Built-in melody IC (not shown)
A predetermined song is selected from among the songs and played (step S32). At the same time, the characters "OPEN" on the guide display 10 are flickered during the refueling operation (step S33). Then, the CPU 28 monitors whether or not the pulse signal from the flow rate transmitter 8 is being input, that is, whether or not the refueling operation is being continued (step S34). When the insertion sensor 16 is opened, it is determined that the refueling nozzle 15 has been removed from the fuel tank with its valve open (step S35), and the mode "H" is displayed on the guide display 10. (Step S36), the speaker 12 emits a voice saying "Please close the nozzle lever" (Step S37), and returns to step 24, where it is monitored whether or not the refueling nozzle 15 is hooked to the nozzle housing 18. Do this. In the present invention, as described as the basic operation in conjunction with FIG. 5, when the insertion sensor 16 is opened, the motor 5 can be stopped regardless of whether the nozzle switch 19 is opened or closed. After the insertion sensor 16 is opened, oil will not overflow even if the oil supply nozzle 15 remains open. Next, in step 34 described above, the CPU 2
When the input of the pulse signal to 8 stops, it is determined that the refueling nozzle 15 is closed, and the melody playing from the speaker 12 is stopped (step S38).
In the next step S39, it is determined whether or not the tank is to be refueled completely. In other words, whether or not refueling is full is determined based on whether a full tank signal is input from the liquid level sensor 17, and the full tank signal is input to the CPU.
28, the CPU 28 stops the motor 5 and makes a sound from the speaker 12 saying, "The tank is full. Please close the nozzle lever and return the nozzle to the weighing machine." S40). On the other hand, the information display 10 shows the form "I".
and "J" are alternately flickered and the characters "FILL" representing full tank are displayed, and the fuel supply nozzle 15 is pulled out from the fuel tank and guided to be hung on the nozzle storage part 18. This flicker display continues until the insertion sensor 16 is opened, and when the insertion sensor 16 is opened (step
S42), the configurations "J" and "K" are alternately flickered on the guide display 10 to prompt the user to hang the refueling nozzle 15 in the nozzle storage portion 18, and then the process returns to step S24. In the present invention, as described as the basic operation with reference to FIG. 5, when the liquid level sensor 17 outputs a full tank signal, the motor 5 is stopped and the weighing machine 1 is interlocked, and the process proceeds to step S48.
After returning to step S24, the refueling nozzle 15
Do not hang the insert sensor 1 on the nozzle storage part 18.
Even if 6 is closed again (see step S23),
The motor 5 will not restart unless the vehicle is moved from the refueling area and the interlock is released again. Next, if it is determined in step S39 that the tank is not fully refueled, the form "H" is displayed together with the letters "SHUT" on the guide display 10 to prompt the valve to close (step S39).
S44), while speaker 12 said, "Ping-pong refueling has finished. Please return the nozzle to the weighing machine."
is uttered (step S45), and in the next step S46 it is determined whether or not the insertion sensor 16 is opened. If the insertion sensor 16 is currently open, the refueling nozzle 15 has been removed from the fuel tank, so the CPU 28 will display the guide indicator 1.
0 is alternately flickered in the form "L" and "M" (step S47), and the process returns to step S23. At this time, if the insertion sensor 16 closes again in step S23, it means that additional oil supply has started, and steps S26 and subsequent steps are repeated. Also, as determined in step S46, the insertion sensor 16
remains closed, CPU2
8 determines whether or not a pulse signal has been input from the flow rate transmitter 8 in the next step S48, and when the pulse signal has been input, it is determined that additional refueling has started, and the process returns to step S32 described above. , each process including starting the melody performance is repeated.
At the same time, the CPU 28 is activated by the soft timer 31 when the insertion sensor 16 is opened (step
(see S46)) (step S49),
If the pulse signal does not arrive for 10 seconds, the guide display 10 will alternately flicker display the formats "P" and "L" (step S50), and at the same time, the speaker 12 will display the message "ping pong." When refueling is finished, return the nozzle to the metering machine. Please say "Please."
After that, the process returns to step S46 and continues until the insertion sensor 16 is opened or additional lubrication is started.
Repeat S46, S48 to S51. However, if the refueling nozzle 15 is removed from the fuel tank during refueling as described in steps S34 to S37, or if the refueling nozzle 15 is removed from the fuel tank after refueling is full, as described in steps S39 to S43. If so, the process returns to step S24, and it is determined in step S24 whether or not the refueling nozzle 15 has been hooked to the nozzle storage portion 18. On the other hand, step
As described in S39 and S44 to S47, when the refueling nozzle 15 is removed from the fuel tank during normal refueling, the process returns to step S23 and steps S23 and S24 are performed.
Then, it is determined whether or not the refueling nozzle 15 is hung in the nozzle storage portion 18 without additional refueling. In each of the three cases described above, the refueling nozzle 15 is opened once to perform substantial refueling, so the value displayed on the counter 9 is not zero. Therefore, after opening the nozzle switch 19 (step S24), the CPU 28 determines whether the displayed value of the counter 9 is zero. If this value is not zero, the CPU 28 moves to the next step S52 and determines whether or not the tank is refueled at full capacity. . In the case of normal refueling where the liquid level sensor 17 does not output a full tank signal, the guide indicator 10
At the same time, the form "N" including the letters "END" is displayed on the screen (step S53), and the speaker 12 outputs "This is Ping Pong XX Little. This is XX Little."
Thank you very much. Don't forget to close your car's fuel filler cap. ” is uttered (step S54). On the other hand, in the case of full tank refueling where a full tank signal is output from the liquid level sensor 17, the information display 10 displays the form "O" including the characters "END" and "FILL" (step S55),
Speaker 12 said, “This is Little Ping Pong.
○× Little. Thank you very much. Don't forget to close your car's fuel filler cap. ” is uttered. Furthermore, in the next step S57, the CPU 28 uses the soft timer 31 to determine whether 30 seconds have elapsed since the nozzle switch 19 was opened, and the nozzle switch 19 remains open even after 30 seconds. If it is determined that
S58), displays the form "C" on the guide display 10 and flickers the arrow 10g (step S59), and emits a voice saying "Please return the ping pong nozzle" from the speaker 12 (step S60). Then, in the next step S61, the refueling nozzle 15 is returned to the nozzle storage section 18, and when the nozzle switch 19 is opened, the process returns to step S1. Thus, the series of refueling operations has been completed, and the vehicle has left the refueling area and the vehicle sensor 2
If 0 is opened, the system will be in a standby state for refueling the next vehicle. Then, when the next car approaches, the vehicle sensor 20 is closed again, the card is inserted into the card reader 22, and the weighing machine designation switch 23 is operated, the interlock of the weighing machine 1 is canceled and the next refueling is started. Process. Next, regarding the case of preset lubrication,
The process will be described according to the flowcharts shown in FIGS. 7A and 7B.
In FIGS. 7A and 7B, the same step numbers as those described in FIGS. ...O, P are each form A, B, C...O, of the guide display 10 shown in FIG.
Represents P, and lowercase letters a, b, d,...c',
m and n represent uttered audio phrases shown in Table 2 below. Note that there are no changes between Tables 1 and 2 except that the symbol c in Table 1 has been replaced with the symbol c' in Table 2, and the symbols m and n have been newly added.

[Table] However, the processing up to step S18 in the flowcharts of FIGS. 7A and 7B is the same as in the case of normal refueling described above. By the way, in the case of this embodiment, in step S19, the speaker 12 is
As shown by the symbol "C'" in the middle, remove the ping pong nozzle and set it in the fuel filler port of your vehicle.If you wish to preset refueling, set the desired amount of refueling using the preset switch before removing the nozzle. Please set it.'' is uttered, and the preset in case of preset lubrication is guided by voice. Therefore, the operator must remove the refueling nozzle 15 from the nozzle housing 18 and close the nozzle switch 19 as in step S20, and within 30 seconds after the card is read by the card reader 22 (or POS 26) (step S21). ), operate the preset switch 11 to set the desired oil supply amount (see step S71). As a result, the CPU 28 operates the preset switch 11 without removing the refueling nozzle 15 within 30 seconds after the weighing machine designation signal is input from the weighing machine designation switch 23 and the card reading signal is input from the card reader 22. When the preset amount is stored in the RAM 29,
Then, the ROM 30 is accessed and the speaker 12 is made to utter the voice corresponding to "m" in Table 2, "This is the preset refueling of XX liters" (step S72). After the presetting in steps S71 and S72 is thus completed, the refueling nozzle 15 is removed from the nozzle housing 18 in the next step S20. Therefore, when the nozzle switch 19 is closed, the step
During S22 to S44, the same procedure as the normal refueling described above is performed. During this period, the input of pulse signals to the CPU 28 stops (step S34), and if the tank is not fully refueled (step S39), the CPU 28 displays the form "H" on the guide display 10 (step S34).
S44), it is determined whether or not preset lubrication is to be performed (step S73). If it is preset lubrication, the CPU 28 compares the preset amount with the actual lubrication amount, and when the two values match, outputs a quantitative signal to the motor drive control circuit 38, which causes the motor 5 to stop and outputs a pulse signal. is determined to be no longer input. Therefore, when the CPU 28 outputs the quantitative signal, it determines that preset oil is being supplied, and the speaker 12
``The preset refueling of the
S47). Thereafter, the same processing as described above is performed from step S46. On the other hand, if it is determined in step S73 that preset lubrication is not performed, the step S73 is repeated as described above.
Normal refueling processing is performed from step S46 via S45. In the case of preset lubrication, the processing operations other than those described above are the same as normal lubrication, and will therefore be omitted. In the embodiment of the present invention, an outdoor reader/printer 21, card reader 22, and weighing machine designation switch 2 are used.
3, and the card reading signal and weighing machine designation signal are used as interlock release signals, but if there is only one weighing machine 1, the weighing machine designation switch 23 is abolished, and the process,
That is, steps S12 to S17 can be omitted.
In addition, if the card reader 22 is not used,
Steps S5 to S11 and S21 can be omitted. Further, if only the vehicle approach signal from the vehicle sensor 20 is used as the interlock release signal, the process may proceed from step S2 to step S18. In addition, in the embodiment, the guide display 10 for providing guidance to the operator is shown in FIG. 4, which is made up of the nozzle positions, arrows, and letters. Therefore, the guidance display 10 can guide the operation procedure.
When the figures, characters, etc. of , are different, the forms A, B, . . . , O, P shown in FIG. 5 are also different. Furthermore, in the embodiment, the voice phrases shown in Table 1 or Table 2 are uttered by voice synthesis from the speaker 12 in combination with the guide display 10, but the voice phrases are not limited to these. Of course, any audio phrase suitable for guidance can be adopted as appropriate. The refueling method according to the present invention is as described in detail above, and the determining means determines whether the operating state of the weighing machine is normal operation or erroneous operation based on the detection result from the detector that detects the operating state of the weighing machine. Based on the determination result inputted from the determining means, the operation instruction means instructs the drive control means to perform the next normal operation if the operation is normal, and returns the drive control means to the predetermined normal operation if it is an incorrect operation. Instruct the return operation to
In addition, since the drive control means is configured to use an alarm to guide the next operation in response to an instruction input from the operation instruction means, accurate guidance can be provided as the refueling operation progresses, and the metering If an error occurs during operation of the machine, the system can instruct you to perform the next correct operation at that point.
This can prevent a situation in which the refueling operation continues due to an incorrect operation.
