FIG. 2 is a block circuit diagram used in the present invention, in which the nozzle removal signal A from the nozzle switch 10 is introduced into the motor control circuit 18 as an on signal A-1, and into the counting circuit 19 as a reset signal '4A-2. The flow rate signal B from the pulse transmitter 7 provided in the flow meter 4 is introduced into the counting circuit 19, the count signal C from the counting circuit 19 is introduced into the display meter drive circuit 20, and the drive signal from the display meter drive circuit 20 is inputted. Display total 11
to be introduced.

The count signal E from the counting circuit 19 is introduced into the comparison circuit 21, while the oil supply amount setting device 14 performs preset oil supply.
A setting signal F is introduced into the comparator circuit 21 via a setting circuit 23 that stores a set numerical value.

The comparison circuit 21 is a circuit that compares the flow rate value of the set value based on the setting signal F and the count signal E from the counting circuit 19, and issues an output signal G when the two match.

Of the output signals G from the comparison circuit 21, the off signal G-
1 to the motor control circuit 18, the ON signal G-2 to the alarm 13, and the drive signal H from the motor control circuit 18.
is introduced into motor 8.

Introduce the signal engineer into the timer 24 and set the timer 24's time. The signal J is sent to the clock 12, and the output signal K, which is generated in the fourth year and 11th month after receiving the above setting signal ■, is sent to the AND circuit 25.
Then, the output signal generated during the 5-year certification period is connected to AND circuit 2.
6, a control signal M for dynamic drive is introduced into the display meter drive circuit 20.

Further, the power-on signal N that is generated when the main switch 15 is powered on is introduced into the AND circuits 25 and 26, and the ON signal 0 from the AND circuit 25 is input to the alarm 13, and the output signal P of the AND circuit 26 is input to the ON signal. Alarm 13 as P-1
Then, it is introduced into the display meter drive circuit 20 as a blinking signal P-2 and into the motor control circuit 18 as a lock signal P-3.

Next, to explain the usage and operation, at the time of certification, operate the certification deadline setter 16 to introduce the setting signal ■ to the timer 24, and after 4 years and 11 months, signal K to the AND circuit 25.
AND circuit 26 so that it will emit for 0 seconds, after 5 years
Set the signal so that it continues to emit a signal.

In normal operation of the oil supply system, when the nozzle valve 6 is removed from the nozzle hook 9, the nozzle switch 10 outputs an on signal A.
-1 is introduced into the motor control circuit 18, the motor 8 is started via the drive signal H of the motor control circuit 18, and the chimp 3 is assisted.

On the other hand, the reset signal A-2 is sent from the nozzle switch 10.
is introduced into the counting circuit 19, the previous count memory is reset to zero, and the display counter 11 is reset by the signal C from the counting circuit 19.
is returned to zero.

Further, when the oil supply amount setter 14 is operated to set a planned oil supply amount (for example, 20 tons), this set amount is introduced as a setting signal F to the comparison circuit 21 via the setting circuit 23.

When the nozzle valve 6 is inserted into the fuel filler port of a car and is opened to refuel, the flow rate signal B from the pulse transmitter 7 is introduced into the counting circuit 19 and counted there, and the counting signal C from the counting circuit 19 is displayed. The display meter drive circuit 20 issues a drive signal to the display meter 11, and the display meter 11 displays the amount of oil supplied on each side.

At this time, a control signal M for dynamic drive is introduced from the timer 24 to the display meter drive circuit 20, and the display meter drive circuit 20 dynamically drives the display meter 11.

Further, the count signal E is sent from the count circuit 19 to the comparison circuit 21 every moment.
will be introduced in

The comparison circuit 21 compares the setting value of the setting signal F and the oil supply value of this count signal E, and when the setting value is larger, no signal is output, but when the two match, the motor control circuit 18 An off signal G-1 is generated as an output signal G, and the motor control circuit 18 receives this off signal G-1 and stops the shimo motor 8 with the drive signal H. As a result, the pump 3 is also stopped and the refueling is stopped. finish.

At the same time, the output signal G of the comparison circuit 21 is introduced to the alarm 13 as an on signal G-2, and the alarm 13 continues to sound for a certain period of time to notify the end of refueling.

Note that a constant time signal J is introduced from the timer 24 to the clock 12, and the clock 12 displays the time.

When the period of use of the refueling device reaches 4 years and 11 months, the output signal K from the timer 24 is introduced to the AND circuit 25, and the main switch 15 is closed to turn on the power at the beginning of the usage of the refueling device, such as in the early morning. When the generated power-on signal N is also introduced into the AND circuit 25, the AND circuit 25 introduces the ON signal 0 to the alarm 13, and the alarm 13 continues to sound for about 10 seconds. You can know something.

After that, if the user continues to use the product without completing the certification procedure and reaches the 5-year certification period, the timer 24 outputs an output signal to the AND circuit 26, and the same power is generated when the main switch 15 is closed to turn on the power. When input signal N is also introduced into AND circuit 26, AND circuit 26 issues output signal P.

This output signal P is introduced to the alarm 13 as an on signal P-1, which sounds, and is also introduced to the display meter drive circuit 20 as a blinking signal P-2, and is transmitted via the drive signal from the display meter drive circuit 20. The display meter 11 indicates the verification period (for example, 56-
10) is displayed and blinks.

The ringing of the alarm 13 and the flashing of the indicator 11 let the worker know that the verification deadline has arrived.

Further, the output signal P is introduced to the motor control circuit 18 as a lock signal P-3, and the motor 18 becomes undriveable, and the entire oil supply system becomes unusable from then on. After completing the verification procedure, the setting device 16 is set again to a new verification deadline, and the refueling machine becomes operational.

As described above, in the oil supply device of the present invention, the device becomes unusable after the verification period has elapsed, so it is possible to prevent unauthorized use of the device by continuing to use it without undergoing verification after the verification period has elapsed.

In addition, the timer used can be manufactured at low cost since it is a shared timer used for other purposes.
