Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a liquid supply device having a training function for an operator.

(Prior Art) With the development of electronic technology such as microcomputers, computerized liquid supply devices that automatically perform everything from liquid supply operation control to data processing have become widespread, contributing to the simplification of normal work.

However, the operation of devices with such diverse functions is complicated, making it difficult for first-time users to operate them.
It doesn't make sense to me at all and gives me a great feeling of anxiety.

For this reason, simulators configured for training are used, and training for experienced personnel is conducted using actual machines, but in the former case, it is necessary to have a simulator at each refueling station, so the equipment There is the problem of increased costs, and since the latter involves actual liquid supply operations, it not only poses a safety problem, but also an error between the cumulative value of the daily counter or total counter and the sales volume. There is an inconvenience that this occurs.

(Objective) In view of the above circumstances, it is an object of the present invention to provide a liquid supply device that allows training using an actual machine to be safely performed without causing changes in sales data.

(Structure) Therefore, details of the present invention will be described below based on illustrated embodiments.

FIG. 1 shows an embodiment of the present invention, and reference numeral 1 in the figure denotes a control device that uses command signals from a keypad 3 and a card reader 4 provided outside the main body 2 of the device.
The pump drive motor 6 is operated based on the signal from the nozzle switch 5, and the flow pulse from the flow pulse transmitter 8 generated by the opening of the valve provided in the nozzle 7 is integrated and displayed on the display 9, and at the same time p via the transmission line lO,
o, a refueling mode that outputs sales data to the s device 11;
It is configured such that a training mode can be set in which a pseudo flow rate pulse is generated while the pump drive motor 6 is kept inactive by a signal from the nozzle switch 5, and its integrated value is displayed on the display 9. In addition, in the figure, reference numeral 25 indicates a liquid pump, and 26 indicates a flow meter.

FIG. 2 shows an embodiment of the above-mentioned control device, in which reference numeral 1 is the main body of the above-mentioned control device, and card type determining means 12 for determining the type of card inserted into the card reader 4. , a display content storage means 14 storing display data for displaying the type of card and the type of set mode on the display 13; while holding the designated operation mode; Processing mode storage means 1 that cuts off power to the pump drive motor and deactivates liquid supply data storage means 18, which will be described later.
5. When the training mode is set, the pulse oscillation means 16 outputs a simulated flow rate pulse, the calculation means 17 receives the input of the flow rate pulse or the simulated flow rate pulse and calculates the liquid supply amount, and the actual liquid supply is performed. a nozzle switch 4. Flow rate pulse transmitter 8, keypad 3. It is configured to input signals from the card reader 4 and to output signal processing contents to the display 9 and control signals to the pump drive motor 6.

11 is the aforementioned p, o, and s device, which includes a transmitting/receiving means 20 connected to the transmitting/receiving means 19 on the control device side via the transmission line 10 to receive and receive flow rate data, and a receiving/receiving means 20 for processing the received data. It is composed of a liquid data processing means 21, a liquid supply data storage means 22 for sequentially integrating processed data, and a display 23 and a printer 24 for displaying and printing processed data.

Next, the operation of the apparatus configured as described above will be explained based on the flowchart shown in FIG.

[Liquid supply mode] In this state, insert the liquid supply card into the card reader 4.
When the card is read by the card type discriminating means 12, the card data is read and the liquid supply mode is set, and at the same time, the display 13 displays the data from the display content storage means 14 to indicate that it is the liquid supply mode. It will be done.

After completing these preparations, when the nozzle 7 is removed from the nozzle hook, the nozzle switch 5 is turned on and the display 9 is turned on.
returns to zero, and at the same time the pump drive motor 6 operates. In this state, when the valve of the nozzle 7 is opened to start liquid supply, the calculation means 17 integrates the signal from the flow rate pulse generator 8 and outputs it to the display 9. When a predetermined amount of liquid has been supplied in this way and the nozzle 7 is set to the nozzle hook, the nozzle switch 5 is turned OFF, the pump drive motor 6 is turned OFF, and at the same time a liquid supply end signal is output.

On the other hand, the P, O, S device 11 receives the liquid supply data input during this liquid supply period, calculates the liquid amount for each liquid type, and prints out the liquid supply amount by the printer 24 based on the liquid supply signal. (Figure 3 ■).

[Training Mode] After reading the responsible person's card on the card reader 4, when the training mode is set using the keypad 3, display data is output from the display content storage means 14 and a message indicating that the training mode is in effect is output on the display 13. to indicate to the operator that training mode is set.

After completing these preparations, remove the nozzle 7 from the nozzle hook and the nozzle switch 5 will turn on.

This causes the contents displayed on the display 9 to return to zero. However, in this case, since the training mode is set, the pump drive motor 6 is de-energized by the signal from the processing mode storage means 15 and maintained in an inactive state. In such a state, when a certain period of time required for inserting the nozzle into the fuel tank of the automobile has elapsed, the simulated flow rate pulse oscillation means 16 starts operating and outputs a simulated flow rate pulse to the calculation means 17. The calculation means 17 integrates the inputted simulated flow rate pulses in the same way as the pulses from the flow rate pulse transmitter and outputs them to the display 9 to display numerical values in the same format as in normal work. On the other hand, the liquid supply data storage means 18 retains past sales liquid supply data without taking in the data output from the calculation means 17.

In this way, once the hydration training is completed,
When the valve of the nozzle 7 is closed, the operation of the simulated flow rate pulse generating means 16 is stopped and the integrated value is displayed on the display 9. When the training is completed, the nozzle 7 is set on the nozzle hook.

If the nozzle 7 is removed from the nozzle hook in such a state, the above-mentioned process is repeated again, and operations such as valve operation and the accompanying operating state of the indicator 9 are simulated without liquid supply operation. do.

[Registration mode] Insert the unit price setting card and liquid type setting card into the card reader 4.
When the card is read, the card type determining means 12 reads the contents of the card and displays on the display 13 that the card is in registration mode, while setting the storage means (not shown) that stores the basic data to a rewritable state. do. If unit price data and liquid type data to be changed are input from the keyboard 3 at this point, the data will be displayed on the display 13, and then the contents of the storage means will be updated.

(Effects) As described above, according to the present invention, a pulse signal resembling a flow rate pulse is generated without discharging liquid by external operation, and this is counted and displayed.
Since the total counter can be maintained in an inactive state depending on this pulse signal, it is possible not only to safely practice operating procedures using an actual machine without discharging fluid, but also to prevent fluctuations in sales volume. It cannot be caused.
